II Guideline Application
Purpose and objectives
The purpose of this guideline is to provide a summary of the current knowledge about fetal growth restriction (FGR), focusing on the definition, diagnosis and management of care to determine the best time to deliver the fetus.
Targeted areas of care
-
Inpatient care
-
Day-patient care
-
Outpatient care
Target user groups/target audience
This guideline is aimed at the following groups of people:
-
Gynecologists and obstetricians
-
Neonatologists
-
Pediatricians
Adoption and period of validity
The validity of this guideline was confirmed by the executive boards/representatives of the participating professional medical societies, working groups, organizations, and associations as well as the boards of the DGGG, the DGGG Guidelines Commission, the OEGGG and the SGGG in September 2024 and was thereby approved in its entirety. This guideline is valid from 1 October 2024 through to 30 September 2029. Because of the contents of this guideline, this period of validity is only an estimate. The guideline can be reviewed and updated earlier if urgently necessary. Similarly, if the guideline still reflects the current state of knowledge, its period of validity can be extended.
III Method
Basic principles
The method used to prepare this guideline was determined by the class to which this guideline was assigned. The AWMF Guidance Manual (version 1.0) has set out the respective rules and requirements for different classes of guidelines. Guidelines are differentiated into lowest (S1), intermediate (S2), and highest (S3) class. The lowest class is defined as consisting of a set of recommendations for action compiled by a non-representative group of experts. In 2004, the S2 class was divided into two subclasses: a systematic evidence-based subclass (S2e) and a structural consensus-based subclass (S2k). The highest S3 class combines both approaches.
This guideline was classified as: S2k
Grading of recommendations
The grading of evidence based on the systematic search, selection, evaluation, and synthesis of an evidence base which is then used to grade the recommendations of the guideline is not envisaged for S2k guidelines. The individual statements and recommendations are only differentiated by syntax, not by symbols ([Table 3]).

Statements
Expositions or explanations of specific facts and circumstances, or problems without any direct recommendations for action included in this guideline are referred to as “statements.” It is not possible to provide any information about the level of evidence for these statements.
Achieving consensus and level of consensus
At structured NIH-type consensus conferences (S2k/S3 level), authorized participants attending the session vote on draft statements and recommendations. The process is as follows. A recommendation is presented, its contents are discussed, proposed changes are put forward, and all proposed changes are voted on. If a consensus (> 75% of votes) is not achieved, there is another round of discussions, followed by a repeat vote. Finally, the level of consensus is determined, based on the number of participants ([Table 4]).

Expert consensus
As the term already indicates, this refers to consensus decisions relating specifically to recommendations/statements issued without a prior systematic search of the literature (S2k) or where evidence is lacking (S2e/S3). The term “expert consensus” (EC) used here is synonymous with terms used in other guidelines such as “good clinical practice” (GCP) or “clinical consensus point” (CCP). The strength of the recommendation is graded as previously described in the chapter Grading of recommendations but without the use of symbols; it is only expressed semantically (“must”/“must not” or “should”/“should not” or “may”/“may not”).

|
|
Statement: new |
The definitions of constitutionally small and growth-restricted fetuses are very heterogeneous and definitions in international guidelines differ [1], [2], [3], [4].
A fetus or neonate is considered small for gestational age (SGA) if the estimated fetal weight or the birth weight is less than the 10th percentile. A diagnosis of SGA only describes a fetal weight which is at the lower end of the normal growth distribution, but this is not directly associated with pathological growth. It also includes constitutionally small children who will not necessarily be affected with higher perinatal morbidity. However, the lower the percentile, the greater the likelihood of a real FGR situation.
Depending on the gestational age at diagnosis, clinicians differentiate between early FGR (< 32 + 0 GW) and late FGR (≥ 32 + 0 GW) [2], [5]. There are relevant differences in the clinical course of early and late FGR and these must be taken into account (see chapter 6: Management of FGR).
2 Epidemiology and etiology
Consensus-based recommendation 2.E1 |
|
---|---|
Expert consensus |
Level of consensus +++ |
All pregnant women must be evaluated for potential risk factors for FGR by taking their detailed medical history. If risk factors are found to be present, further diagnostic examinations must be considered or offered. |
|
Recommendation: new |
FGR is a condition which affects about 5 – 10% of all pregnancies [6], [7]. The etiology of FGR is roughly divided into maternal, placental and fetal causes ([Table 5]) [8]. Although the underlying pathophysiological mechanisms may differ, they often result in the same endpoint: suboptimal uteroplacental perfusion with suboptimal provision of nutrients to the fetus.
Maternal causes |
Alcohol abuse [10] Maternal hypertensive disease in pregnancy (preeclampsia, gestational hypertension) [11] Drug/nicotine abuse [12], [13] Embryotoxic or fetotoxic medications [14] Maternal age (≥ 35/>40 years) [15] Maternal weight (high or very low BMI) [16] Low socioeconomic status [17], [18] Nulliparity [19] Subclinical cardiovascular dysfunction [20] s./p. hypertensive disease in a previous pregnancy s./p. IUFD [11] s./p. SGA/FGR [11] Preexisting maternal disease which could result in reduced uteroplacental perfusion or reduced oxygenation of maternal blood, e.g., chronic respiratory disease chronic hypertension [21] chronic renal disease [22] diabetes mellitus with vascular disease [23] cyanotic heart disease [24] severe anemia systemic lupus erythematosus and antiphospholipid syndrome [25] |
Uteroplacental causes |
Placental abruption [26] Velamentous cord insertion Placental infarction [27] Disorders of placentation with insufficient invasion of the trophoblast and high maternal risk of preeclampsia [28] Placental tumors Singular umbilical artery [29] |
Fetal causes |
Chromosomal disorders and syndromal diseases [30], [31] Fetal infections (esp. cytomegalovirus, toxoplasmosis, rubella, varicella-zoster virus) Multiple pregnancy [32] |
It is essential that the mother is asked in detail about her medical history. This helps to identify pregnancies with a higher risk of FGR which will require close monitoring [9].
3 Diagnostic workup to evaluate for possible FGR
In addition to the information obtained from the motherʼs medical history, a clinical examination with instrument-based diagnostic procedures must be carried out to exclude or confirm FGR. This is an important aspect of antenatal care as the majority of FGR cases are not detected prenatally [33] and undetected FGR has an 8 times higher risk of intrauterine fetal death [34].
3.1 Clinical examination
Consensus-based recommendation 3.E2 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Clinical examinations to screen for FGR are of limited use. If abnormalities are suspected, an examination must be carried out based on ultrasound biometry. |
|
Recommendation: confirmed |
3.2 Sonography
3.2.1 Crown-rump length
Consensus-based recommendation 3.E3 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The maternal history-based gestational age must be verified by measuring the crown-rump length in early pregnancy and must be corrected if there is a discrepancy of more than 7 days. In Switzerland, the due date is corrected if there is a discrepancy of more than 5 days, in accordance with the requirements of the SGUM guidelines. |
|
Recommendation: new |
When carrying out a diagnostic workup to exclude or confirm possible FGR, it is essential to review the maternal history-based gestational age. Estimating the gestational age by measuring the crown-rump length (or the biparietal diameter) in early pregnancy in accordance with maternity guidelines provides the most reliable data compared to all other methods [9], [10], [11]. Unless the date of conception was fixed (e.g., ICSI), the gestational age must always be corrected if the maternal history-based gestational age deviates from the sonographically determined age by at least 7 days [35], [36], [37].
However, if screening is carried out in the first trimester of pregnancy, the guideline “First Trimester Diagnosis and Therapy in Weeks 11 – 13+6 of Gestation” (AWMF Registry No. 085/002, Level: S2e) and its recommendation 4.1 should be consulted [38]:


When carrying out first trimester screening in accordance with the guideline, specific reference curves based on crown-rump length must be used to determine the gestational age. In this setting, if the exact date of conception (e.g., ICSI) is not known, the crown-rump length must always be used to determine gestational age.
3.2.2 Measurement of the fetus
Consensus-based recommendation 3.E4 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Further diagnostic evaluations must be carried out if the estimated fetal weight/abdominal circumference is less than the 10th percentile. |
|
Recommendation: confirmed |
Fetal abdominal circumference is the most important indicator of FGR in addition to estimated weight. A discrepancy between fetal abdominal and fetal head circumference may also be an indication of FGR.
Evaluating the estimated fetal weight should also take maternal and paternal characteristics into consideration. Parental height, weight, and ethnicity affect fetal weight, which is why growth curves which were adapted to take account of these factors may be useful [39], [40], [41], [42].
As FGR is not limited to a weight below the 10th percentile, repeat measurement of the fetus may be useful, especially if risk factors are present; however, repeat measurements should be carried out two weeks later at the earliest to minimize the methodological bias of weight formulas as much as possible.
3.2.3 Amniotic fluid
Consensus-based recommendation 3.E5 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The amniotic fluid volume should be evaluated when investigating for possible FGR. |
|
Recommendation: new |
3.2.4 Detailed sonographic investigation (further, more differentiated, diagnostic examination of organs)
Consensus-based recommendation 3.E6 |
|
---|---|
Expert consensus |
Level of consensus +++ |
When investigating for possible SGA/FGR, the detailed diagnostic examination should include sonography. |
|
Recommendation: confirmed |
3.3 Doppler sonography
Consensus-based recommendation 3.E7 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Doppler sonography must be done to investigate for possible FGR. |
|
Recommendation: confirmed |
3.4 Cardiotocography (CTG)
Cardiotocography (CTG) is known to have a high false-positive rate for the prediction of poor outcomes and is better at detecting acute hypoxic conditions than identifying a chronic course [43]. The usefulness of CTG to investigate for possible FGR is therefore somewhat limited but it should be carried out as recommended in maternity guidelines in the context of standard antenatal screening if there is a suspicion of placental insufficiency [44].
4 Differential diagnostics for a SGA/FGR fetus
4.1 Genetic investigation
Consensus-based recommendation 4.E8 |
|
---|---|
Expert consensus |
Level of consensus ++ |
A genetic investigation should be recommended in cases with severe FGR (estimated fetal weight < 3rd percentile, early FGR) when sonography findings indicate a genetic cause and these findings are expected to affect management of the condition. |
|
Recommendation: new |
4.2 Investigation for infection
Consensus-based recommendation 4.E9 |
|
---|---|
Expert consensus |
Level of consensus ++ |
An investigation for infection should considered if the fetus is SGA or has FGR. |
|
Recommendation: confirmed |
5 Summary: diagnosis of FGR
The differential diagnostic procedures used to arrive at a diagnosis of FGR are shown in [Fig. 1].


6 Management of FGR
There is very little evidence on the most suitable method for prenatal monitoring of FGR [45]. A single monitoring method is not able to effectively predict the outcome of FGR, which is why a combination of different methods to monitor growth-restricted fetuses is recommended. Sonography, especially Doppler sonography, is essential to monitor FGR and improve perinatal outcomes.
6.1 Diagnostic monitoring of changes over time
Diagnostic monitoring of changes over time facilitates the differential diagnosis of any placental function disorders and provides a more exact prognostic assessment of the perinatal risk. Most importantly, a combination of biometry and Doppler sonography may reduce perinatal mortality.
6.1.1 Clinical examination
Consensus-based recommendation 5.E10 |
|
---|---|
Expert consensus |
Level of consensus +++ |
It is important to watch out for preeclampsia, especially in cases with FGR from uteroplacental causes. |
|
Recommendation: new |
6.1.2 Sonography (measurement of the fetus)
Consensus-based recommendation 5.E11 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Serial sonographic assessments of fetal growth must be carried out if FGR is present or suspected. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E12 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The interval between individual sonographic assessments of fetal growth should be at least two weeks. |
|
Recommendation: confirmed |
6.1.3 Sonography (amniotic fluid)
Consensus-based recommendation 5.E13 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Sonographic assessment of the amniotic fluid volume must only be interpreted in the context of other monitoring methods. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E14 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The SDP (single-deepest-pocket) method should be used to assess amniotic fluid volumes. |
|
Recommendation: confirmed |
6.1.4 Doppler sonography (umbilical artery)
Consensus-based recommendation 5.E15 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Doppler sonography of the umbilical artery must be carried out as part of the management of FGR, as the use of Doppler sonography may reduce perinatal mortality in high-risk pregnancies. |
|
Recommendation: confirmed |
Consensus-based statement 5.S3 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Unremarkable Doppler sonography findings of the umbilical artery are associated with a lower risk of a poor perinatal outcome in cases with early FGR. |
|
Statement: confirmed |
Consensus-based statement 5.S4 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Diastolic absent-end flow (AED flow), especially reverse diastolic blood flow (RED flow) in the umbilical artery is often associated with a poor perinatal outcome in cases with FGR. |
|
Statement: confirmed |
Consensus-based recommendation 5.E16 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The intervals between Doppler sonography assessments must always be adapted to the severity of FGR and the Doppler sonography findings. |
|
Recommendation: new |
Consensus-based statement 5.S5 |
|
---|---|
Expert consensus |
Level of consensus +++ |
If Doppler sonography findings of the umbilical artery are unremarkable, repeat assessments appear to be sufficient in cases with early FGR. It may be useful to carry out assessments more often in cases with severe FGR. |
|
Statement: confirmed |
Consensus-based recommendation 5.E17 |
|
---|---|
Expert consensus |
Level of consensus +++ |
It is not clear what the intervals between Doppler sonography assessments should be if Doppler sonography findings of the umbilical artery are pathological. Assessments should be carried out at least once a week in cases with a high pulsatility index (PI > 95th percentile) and assessments should be carried out even more often in cases with ARED flow. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E18 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Doppler sonography assessment of additional vessels (middle cerebral artery, ductus venosus) should be carried out, especially if Doppler sonography findings of the umbilical artery are abnormal. |
|
Recommendation: confirmed |
6.1.5 Doppler sonography (middle cerebral artery)
Consensus-based recommendation 5.E19 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Doppler sonography of the middle cerebral artery should be carried out in addition to Doppler sonography of the umbilical artery in cases with FGR. |
|
Recommendation: confirmed |
Consensus-based statement 5.S6 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Pathological Doppler sonography findings of the middle cerebral artery (PI < 5th percentile) in cases with late FGR at the due date increase the risk of delivery by caesarean section and a poor perinatal outcome. |
|
Statement: confirmed |
6.1.6 Doppler sonography (cerebroplacental ratio, CPR)
Consensus-based statement 5.S7 |
|
---|---|
Expert consensus |
Level of consensus +++ |
It is currently not possible to conclusively establish the value of the cerebroplacental ratio (CPR), i.e., the ratio of the PI of the middle cerebral artery and the PI of the umbilical artery, for monitoring FGR. We will have to await the results of current ongoing studies. |
|
Statement: new |
6.1.7 Doppler sonography (ductus venosus)
Consensus-based statement 5.S8 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Lack of an a-wave or reverse flow of the a-wave on Doppler sonography of the ductus venosus are indications of imminent or already existing acidosis and the risk of fetal death. |
|
Statement: confirmed |
Consensus-based recommendation 5.E20 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Doppler sonography of the ductus venosus must be part of monitoring early FGR. |
|
Recommendation: confirmed |
6.1.8 Doppler sonography (other vessels)
The predictive value of Doppler sonography of the uterine arteries in the last third of pregnancy is not clear as there are no evidence-based data. Doppler sonography of other arteries (e.g., fetal aorta) and veins (e.g., umbilical vein, inferior vena cava) is currently only recommended in the context of medical research because evidence for this is still lacking.
6.1.9 Cardiotocography (CTG)
Consensus-based recommendation 5.E21 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Cardiotocography (CTG) must not be the only method used to monitor FGR. |
|
Recommendation: confirmed |
6.1.10 Computerized CTG (Oxford CTG)
Consensus-based recommendation 5.E22 |
|
---|---|
Expert consensus |
Level of consensus +++ |
In cases with FGR, analysis of short-term variation must be done using computerized CTG (Oxford CTG). |
|
Recommendation: new |
6.1.11 Biophysical profile
Carrying out a BPP is time-consuming and the results are unclear in 15 – 20% of cases, especially for severe SGA fetuses [46]. Moreover, the use of BPP in high-risk pregnancies does not provide a more precise prediction of fetal acidosis [47], [48] nor is it associated with reduced perinatal mortality [49]. BPP has a high false-negative rate in these cases [48].
Other studies have even reported that the caesarean section rate increased when BPP was done but did not improve the perinatal outcomes [49], which is why the BPP score is not generally used in German-speaking countries.
6.2 Antenatal corticosteroids
Consensus-based recommendation 5.E23 |
|
---|---|
Expert consensus |
Level of consensus +++ |
A single administration of antenatal corticosteroids should be done in a case with FGR between 24 + 0 GW and 34 + 0 GW if delivery of the infant is expected within the next 7 days. |
|
Recommendation: confirmed |
6.3 Magnesium sulfate for neuroprotection
Consensus-based recommendation 5.E24 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Magnesium sulfate may be administered for neuroprotection when a preterm birth is expected < 32 + 0 GW as there is some evidence that it has a neuroprotective effect. |
|
Recommendation: confirmed |
6.4 Delivery
6.4.1 Place of birth
Consensus-based recommendation 5.E25 |
|
---|---|
Expert consensus |
Level of consensus +++ |
If FGR is present, the infant must be born in a perinatal center with a neonatal intensive care unit with an experienced team present to ensure immediate continuous care. |
|
Recommendation: confirmed |
6.4.2 Time of birth
Consensus-based recommendation 5.E26 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Early FGR and late FGR must be assessed differently. Increasing deterioration in a case of early FGR is reflected in abnormalities of venous Doppler sonography parameters and, in cases with late FGR, mainly in the cerebral Doppler sonography findings. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E27 |
|
---|---|
Expert consensus |
Level of consensus +++ |
When planning the time of birth, the risks of preterm birth must be weighed up against the risks of remaining in utero. |
|
Recommendation: confirmed |
Consensus-based statement 5.S9 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Gestational age is a significant factor affecting survival without morbidities. |
|
Statement: confirmed |
Consensus-based recommendation 5.E28 |
|
---|---|
Expert consensus |
Level of consensus +++ |
If there are recurrent treatment-resistant decelerations of the CTG, active management must include delivery of the infant. |
|
Recommendation: new |
Given that there is a high false-positive rate, the general rule for active management (= maximum therapy) is that the infant must be delivered in cases with recurrent, treatment-resistant decelerations in the CTG [50]. According to the classification of the FIGO, the definition of repeated decelerations is when they occur in more than 50% of contractions [51]. More than two decelerations per hour were classified as recurrent decelerations in a cohort of early FGR [52].
Consensus-based recommendation 5.E29 |
|
---|---|
Expert consensus |
Level of consensus +++ |
If there is a short-term variation (STV) < 2.6 ms between week 26 + 0 and week 28 + 6 of gestation or a STV < 3 ms between 29 + 0 and 31 + 6 GW, delivery of the infant must be considered. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E30 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The infant must be delivered if the a-wave (AEDF) is repeatedly absent or there is reversed a-wave flow (REDF) on Doppler sonography of the ductus venosus. |
|
Recommendation: new |
Consensus-based recommendation 5.E31 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The infant should be delivered by 32 + 0 GW at the latest if reversed end-diastolic flow (REDF) is detected on Doppler sonography of the umbilical artery. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E32 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The infant should be delivered by 34 + 0 GW at the latest if absent end-diastolic flow (AEDF) is detected on Doppler sonography of the umbilical artery. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E33 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Delivery of the infant from week 37 + 0 of gestation should be aimed for if increased pulsatility (PI > 95th percentile) is found on Doppler sonography of the umbilical artery. |
|
Recommendation: confirmed |
Consensus-based recommendation 5.E34 |
|
---|---|
Expert consensus |
Level of consensus ++ |
Delivery of the infant from week 37 + 0 of gestation may be offered in cases with repeated, isolated, decreased pulsatility on Doppler sonography of the middle cerebral artery (PI < 5th percentile). |
|
Recommendation: new |
Consensus-based recommendation 5.E35 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Delivery of the infant from week 37 + 0 of gestation may be aimed for if the CPR (cerebroplacental ratio) is low. |
|
Recommendation: confirmed |
Calculation of the CPR (cerebroplacental ratio), the ratio of the PI (or RI) of the middle cerebral artery, and the PI (or RI) of the umbilical artery is useful when deciding when to terminate a FGR pregnancy. However, there is no evidence of a precise CPR threshold value which reliably predicts a poor perinatal outcome. Values of < 1 or < 5th percentile are often considered pathological [53]. In a Delphi process, the final consensus was that a CPR < 5th percentile was an important diagnostic criterion for FGR (see chapter 1: Definition) [5]. This threshold value has also been included in international recommendations [2].
Because of concerns about interobserver reliability during Doppler measurement (PI of the middle cerebral artery, CPR, UCR, and ductus venosus), measurements should be repeated within 24 hours for confirmation if the initial findings were pathological to avoid false-positive results, especially if the time of delivery depends on these findings.
Consensus-based recommendation 5.E36 |
|
---|---|
Expert consensus |
Level of consensus +++ |
In the case of an isolated SGA fetus (unremarkable Doppler sonography findings, no additional risks), delivery may be considered from week 39 + 0 of gestation. |
|
Recommendation: new |
Consensus-based recommendation 5.E37 |
|
---|---|
Expert consensus |
Level of consensus +++ |
An isolated SGA fetus (unremarkable Doppler sonography findings, no additional risks) must not be delivered later than the due date. |
|
Recommendation: confirmed |
The parents must be involved in all decisions and the consequences of the different options must be explained. The higher risk of intrauterine fetal death when an observant approach is taken must be set against the higher mortality and morbidity risks of preterm delivery. Close collaboration with the neonatologist is required to provide the parents with sufficient information.
6.4.3 Mode of delivery

Expert consensus |
Level of consensus +++ |
Not every pregnant woman with FGR will require caesarean section. |
|
Statement: new |
Consensus-based recommendation 5.E38 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Delivery may be induced in cases with FGR and unremarkable Doppler sonography findings or a higher pulsatility of the umbilical artery (> 95th percentile), but not for cases with ARED flow, with the aim of achieving a vaginal birth. However, the high risk of complications must be considered and continuous intrapartum monitoring is required. |
|
Recommendation: confirmed |
6.4.4 Other recommendations
Outpatient or inpatient care
Consensus-based recommendation 5.E39 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The decision whether a pregnant woman with FGR should receive inpatient or outpatient care should be made on a case-by-case basis. |
|
Recommendation: confirmed |
Bed rest
Consensus-based recommendation 7.E40 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Limiting physical activity and bed rest should not be recommended as part of the management of FGR. |
|
Recommendation: new |
Nutrition
Dietary changes, dietary measures or the intake of additional food supplements (e.g., calcium [54]) showed no benefit [55] and are therefore not recommended.
Abstaining from smoking
Consensus-based recommendation 5.E41 |
|
---|---|
Expert consensus |
Level of consensus +++ |
All pregnant women must be given the recommendation to stop smoking. |
|
Recommendation: new |
Progesterone
There is insufficient evidence that progesterone reduces FGR [56] and it should therefore not be used for this purpose.
Maternal oxygen administration
The studies on the benefits of maternal oxygen administration are inadequate and some of them are not methodologically strong. The studies were evaluated in an older Cochrane analysis which found that the evidence to assess the benefits and risks of maternal oxygen administration is insufficient [57]; maternal oxygen administration should therefore not be carried out.
Other therapies
Many interventions in pregnancy which aim to improve blood flow to the placenta have been investigated [58]. However, neither an increase in plasma volume nor the administration of low-dose ASA [59] or sildenafil [60], [61] were found to be beneficial to prevent FGR and they are therefore not recommended.
Antihypertensive therapy to treat pregnant women with hypertensive disease does not affect fetal growth [62], [63] and should therefore not be used, and nitric oxide donors or vasodilatative substances, both of which have still not been investigated sufficiently, are also not recommended [64]. Irrespective of the above, medication to control maternal blood pressure when the mother has hypertension is useful to prevent maternal morbidity (see guideline “Hypertensive Disorders in Pregnancy: Diagnostics and Therapy”, AWMF Registry No. 015 – 018, Level: S2k).
7 Summary: management of FGR
The management of FGR is shown in [Fig. 2].


8 Information and counseling
A detailed explanatory and advisory consultation on FGR as a complication of pregnancy should be held with the pregnant woman or the expectant parents and must cover the individual course and further implications. It also needs to be explained that in the current case the infant might only be constitutionally small, which is not inevitably associated with higher perinatal morbidity. The discussion should involve an interdisciplinary group and include specialists for antenatal medicine/obstetricians and neonatologists. Depending on the fetal pathology, pediatricians or human geneticists may be additionally called in. In addition to information about possible causes, the information provided should also include short and long-term consequences, the risk of recurrence in a subsequent pregnancy and, where necessary, possible diagnostic examinations.
The pregnant woman must be advised about the increased maternal and infant risk of cardiovascular disease [65]. Intrauterine fetal death, preterm death, neonatal mortality and morbidity and reduced neurological development are more common in FGR fetuses, both in a current pregnancy and in any subsequent pregnancies [66], [67].
The risk of FGR occurring in any subsequent pregnancy is higher [11], [68], [69], especially if there are additional hypertensive complications [6]. A prospective study found that women with FGR in a previous pregnancy had a significantly higher risk of FGR in a second pregnancy compared to women with no previous pregnancy with FGR (23% versus 3%) [70].
9 Prophylaxis
A number of different medical constellations and insufficient placental perfusion over the course of pregnancy are associated with an increased risk of developing FGR. The risk of recurrence of FGR after a previous pregnancy with FGR is between 20 and 30% [71]. A number of different prophylactic approaches have been previously evaluated, only a few of which were found to have any evidence-based benefit.
9.1 Acetylsalicylic acid (ASA)
Consensus-based recommendation 7.E42 |
|
---|---|
Expert consensus |
Level of consensus +++ |
In cases with an increased risk of uteroplacental dysfunction and a risk of FGR, the mother should take low-dose ASA (150 mg) prophylactically from ≤ 16 GW. |
|
Recommendation: new |
9.2 Nutrition
Consensus-based recommendation 7.E43 |
|
---|---|
Expert consensus |
Level of consensus +++ |
There is no evidence that special diets or nutritional supplements provide any benefit and they should therefore not be recommended as preventive measures against FGR. |
|
Recommendation: confirmed |
9.3 Heparin
Consensus-based statement 7.S11 |
|
---|---|
Expert consensus |
Level of consensus +++ |
The evidence for the administration of low-weight molecular heparin is insufficient and it should therefore not be recommended, especially in view of possible severe side effects. |
|
Statement: new |
9.4 Nicotine
Consensus-based recommendation 5.E44 |
|
---|---|
Expert consensus |
Level of consensus +++ |
All pregnant woment must be given the recommendation to stop smoking. |
|
Recommendation: confirmed |
9.5 Nitric oxide (NO donors)
The first study on the efficacy of NO donors in pregnancies at risk for FGR was published by Lees in 1998 [72]. A pilot study of 111 women with a higher risk of FGR and preeclampsia showed that the NO donor pentaerythritol tetranitrate (PETN) was able to reduce the risk of severe FGR and perinatal death by 39% and of preterm birth before the 32nd week by 70% [64]. A subsequent prospective, randomized, double-blind multicenter study based on the initial study was unable to confirm these findings but nevertheless showed that PETN intake was associated with a less severe course in high-risk pregnancies [73]. Follow-up examinations of the children at the age of 12 months additionally showed better outcomes for the children born to mothers who had taken PETN [74]. But the preventive effect of PETN on FGR has not yet been definitively established and the long-term results of the children born in this German study who are now six years old are not yet available.
10 Screening
Early detection of FGR is essential as FGR not only significantly affects the course of pregnancy but also affects the neonatal outcome [33], [75].
10.1 Medical history
Taking a detailed medical history which particularly focuses on potential risk factors for FGR (see chapter 2: Epidemiology and etiology) is very important. By identifying cases with a higher risk of FGR it is possible to initiate suitable measures to closely monitor at-risk mothers and infants [9].
10.2 Clinical examination
(see chapter 3.1: Clinical examination)
10.3 Sonography
Precise determination of the due date using crown-rump length (chapter 3.2.1) is a prerequisite for effective screening. In addition, similar to screening for preeclampsia in the 1st trimester of pregnancy, a combination of different markers (maternal medical history, Doppler sonography of the uterine arteries, mean arterial pressure, PAPP-A, free β-hCG, PlGF, PP13, ADAM 12, and NT) may be used to screen for SGA/FGR [38]. Detection rates of 73% have been reported for FGR with delivery before 37 GW and 46% for FGR in infants delivered after 37 GW have been reported [7], [76].
The last sonography screening in week 29 to 32 of gestation as required by maternity guidelines can detect early FGR but not late FGR. If there is a high risk of FGR, regular growth monitoring and Doppler sonography should be carried out as the pregnancy progresses.
10.4 Doppler sonography
Consensus-based recommendation 8.E45 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Abnormal Doppler sonography findings of the uterine artery such as high pulsatility (PI > 95th percentile) should be followed by regular growth monitoring with sonography and Doppler sonography of the umbilical artery. |
|
Recommendation: confirmed |
