Abstract
Background Delayed sternal closure (DSC) is being increasingly used as an interim support to help the dysfunctional heart in the road to recovery after complex pediatric cardiac surgeries. The purpose of this study was to assess the conduct of DSC at a tertiary care center.
Methods Between 2018 and 2019, 185 consecutive pediatric patients (below 12 years of age) underwent cardiac surgery at a tertiary care center. The incidence and causes of DSC were noted. The various pre, intra and postoperative factors till discharge or demise were noted and analyzed.
Results In this study, DSC was done in 63 patients (34.05%) with a median age and weight of 29 days (18–100 days) and 4 kg (2–12.3 kg), respectively. Transposition of great arteries (TGA) (41.27%) constituted the majority, followed by total anomalous pulmonary venous connection (TAPVC) (26.98%). Myocardial edema (49.21%) was the most common indication for DSC. Mean duration of open chest was 40.75 ± 18.58 hours. All-cause mortality was 19.05% (12/63). On multivariate analysis by logistic regression, the independent predictors of mortality were needed for preoperative mechanical ventilation (OR 42.82, 95% CI = 4.52–406.03, p < 0.001) and development of postoperative sepsis (OR 20.07, 95% CI = 2.12–189.80, p = 0.002).
Conclusions DSC is a safe and effective technique in the management of complex pediatric cardiac surgeries. It provides assistance to the severely dysfunctional myocardium soon after the surgery and helps in stabilization of hemodynamics with avoidance of postoperative mediastinal compression. Early sternal closure should be considered on the basis of cardiovascular function and/or resolution of primary indication for DSC.

The concept of delayed sternal enclosure (DSC) and open chest management for cardiomediastinal mismatch in adults was first described by Riahi et al in 1975.[1] Subsequently, many studies have established the usefulness of DSC in postcardiac surgery both in adults and children.[2] [3] [4] A rise has been observed in edema in myocardium postcardiac surgery for the first 24 hours, which causes a decline in coronary reserve.[5] These effects are more pronounced in the pediatric population, owing to the relatively greater cardiac size with respect to other mediastinal structures and proportionately severe inflammation of cardiopulmonary bypass (CPB) effects on immature pediatric capillaries.[5] Therefore, early attempted sternal closure often fails due to development of myocardial edema, ventricular dysfunction, and hemodynamically significant arrhythmias, all resulting from cardiac compression which, in turn, causes tamponade effect on cardiopulmonary functioning. Leaving the sternum open immediately after surgery thus improves diastolic filling, coronary perfusion, and myocardial oxygen supply, thereby improving myocardial function.[2] [5] [6] DSC can minimize the rise in intrathoracic, intrapleural, and pericardial pressures.[7] It can improve ventricular compliance, thereby improving the cardiac filling. Further benefits include rapid mediastinal access for clot evacuation, requirement of electrical cardioversion, and emergency access for establishing extracorporeal membrane oxygenator (ECMO).[8] The purpose of this study was to evaluate the incidence of DSC in our setup among pediatric cardiac surgery cases, reasons for DSC, and physiologic effects; determine appropriate time for closure; and evaluate the reasons for morbidity and mortality among these patients.
#
Materials and Methods
This prospective observational study was conducted on consecutive pediatric patients below 12 years of age undergoing open heart surgery for complex congenital cardiac lesions in 2 of 8 designated cardiac surgical ORs managed with DSC. This study was conducted from May 2018 and April 2019. Informed written consent was taken from parents/guardian before enrolment. The study was approved by the Institute Ethics Committee and performed in the cardiothoracic surgery center at a tertiary care teaching hospital.
Conduct of Delayed Sternal Enclosure (DSC)
The decision to leave the sternum open was made intraoperatively. The following details concerning DSC were recorded: indication and the time to successful sternal closure.
Chest closure was accomplished by suturing the skin edges with sterile polyurethane transparent membrane (e.g., blood collection bag) and Prolene suture. Povidone iodine ointment was applied and covered with sterile gauze all around over which an occlusive iodine impregnated adhesive dressing was placed.
#
Sternal Closure Procedure
This was performed in cardiothoracic ICU under strict aseptic precautions. First, careful detachment of sterile sheet was undertaken from skin and mediastinal devices. The polyurethane bag was detached. Two culture swabs were taken from the inner sternal surfaces for microbial assessment. Excessive adhesiolysis was avoided. The sternal closure was achieved with Ethibond sutures after gentamycin saline irrigation. The skin was closed with interrupted nonabsorbable Prolene sutures. Occlusive dressing was put over povidone iodine ointment with a sterile gauze.
#
ICU Management
Patients were kept on mechanical ventilation with invasive monitoring under sedation and paralysis, which was achieved with fentanyl infusion (1–2 mcg/kg/hour) and cisatracurium infusion at 0.2 mg/kg/hour respectively till sternum closure.
Enteral feeding was started approximately 6 hours postsurgery with nasogastric tube, in accordance with our ICU protocol. Loop diuretics were used to achieve cumulative negative fluid balance. The transthoracic echocardiography was done to assess the ventricular contractility, pulmonary pressures, and any residual defects.
#
Antibiotic Protocol
Our ICU protocol delineates broad-spectrum antibiotic coverage with piperacillin-tazobactum and vancomycin given as 100 mg/kg/q8hrly and 15 mg/kg/q8hrly, respectively. These were escalated in case of clinical suspicion of sepsis or culture growth of a particular organism, with clinical picture suggestive of worsening status.
#
#
Statistical Analysis
Continuous variables were expressed as mean ± standard deviation (SD), median with interquartile range, and analyzed using Mann–Whitney test or independent t-test as appropriate. Categorical variables were analyzed using Pearson’s Chi-square test or Fischer exact t-test. Changes within continuous variable were assessed by repeated measure ANOVA (analysis of variance), followed by multiple comparisons using Bonferroni test. A p value of less than 0.05 was considered statistically significant. Univariable and stepwise multiple logistic regression with probability of entry “0.05” and probability of removal “0.1” were performed to assess the independent risk factors for mortality. All statistical analyses were performed using Stata-14 (StataCorp, 4905, Lake way Drive, College Station, Texas, 77845, USA).

Results
During the study period, 63 out of 185 pediatric patients who underwent DSC after congenital cardiac operations were included in this study. Incidence of DSC in our study population was found to be 34% (63/185), with male children constituting the majority (49/63, 77.8%) and the remaining 14 were females (22.2%). Majority of patients were under 1 month of age with a median age of 29 days (18–100 days). Sternum was left open in the OR in all 63 patients with or without a sternal closure trial. Majority of patients were under 6 months of age (82.54%, 52/63), with more than half under 1 month of age (57.14%, 36/63).
The preoperative comprehensive cardiac diagnoses for all these children are delineated in [Table 1]. Arterial switch operation (ASO) constituted the majority (25/63, 39.68%), followed by total anomalous pulmonary venous connection (TAPVC) repair (17/63, 26.98%). One patient of dextro-transposition of great arteries (D-TGA) with ventricular septal defect and left ventricular outflow tract obstruction was managed with Rastelli surgery.
The reasons for leaving the sternum open are summarized in [Table 2], with myocardial edema (49.21%) and nonsurgical hemorrhage (15.87%) constituting the majority.
Mean duration of aortic cross-clamp (ACC) was 48.95 ± 18.41 minutes while that of CPB was 104.40 ± 42.50 minutes. In five patients, DHCA at 20°C was done with a mean duration of 25.2 ± 7.78 minutes. Deep hypothermic circulatory arrest (DHCA) was used in three patients of interrupted aortic arch, one in infracardiac TAPVC, and in one patient with intracardiac mass, extending from superior vena cava to tricuspid valve, with tricuspid valve vegetation having infective thrombus in left pulmonary artery.
Mean duration of open chest was 40.75 ± 18.58 hours. Two patients died before sternal closure due to malignant ventricular arrhythmia in one and severe intracerebral bleed in the other. Daily assessment with bedside echocardiography for ventricular contractility, pulmonary pressures, residual lesions, and pericardial collections was done followed by povidone iodine impregnated dressing under aseptic precautions.
Mean duration of mechanical ventilation (MV) was 142.09 ± 40.73 hours with tracheostomy being performed in 11 patients (17.46%). In cases with prolonged MV or multiple (> 3) failed extubation attempts, tracheostomy was performed. Peritoneal dialysis (PD) was performed in eight patients (12.70%). The reasons for PD catheter insertion are described in [Table 3].
The mean values of TT3 of 0.81 ± 0.40 and TT4 of 39.32 ± 7.63 in the immediate postoperative period, although normal, were significantly lower than predischarge (TT3 = 2.06 ± 0.62, p < 0.001 and TT4 = 73.02 ± 7.33, p < 0.001) values. The mean values of thyroid stimulating hormone (TSH) in the immediate postoperative period = 2.51 ± 1.19 and predischarge time = 2.66 ± 1.15 (p = 0.13) were normal, but higher values were observed at discharge, although it could not approach statistical significance. This could have been due to varied discharge times of the patients. Hypothyroidism was detected in two patients for which thyroxine replacement was done with Ryle’s tube at a dose of 5 micrograms per kilogram. All pediatric cases received the micronutrient and calcium, vitamin D and K supplementation as a part of our ICU protocol.
Hemodynamic and metabolic data (blood gas analysis) are reported in [Table 4]. The next table signifies statistical significance of the variations in these parameters in different time intervals ([Table 5]).
Superficial surgical site infections (SSI) occurred in six (9.5%) patients. Deep space infection (mediastinitis) was observed in three patients (4.76%) poststernal closure. Two of them succumbed. One child could be treated with irrigation of mediastinal cavity with povidone iodine solution and escalation of antibiotics. The sternum was kept open for daily irrigation with warm povidone saline. After the clinical and biochemical parameters settled, the sternal re-fixation was done on the 4th day and skin was closed with interrupted sutures.
Overall, postoperative sepsis developed in 15 patients (23.81%) out of which 7 patients succumbed. Four developed multiorgan failure, two had mediastinitis, and one manifested disseminated intravascular coagulopathy (DIC). The cultures were positive for growth of pathogens in nine patients of which three yielded Pseudomonas aeruginosa and two had Acinetobacter baumanni from endotracheal secretions, one had E. coli in bloodstream, one had Staphyloccus aureus from central line tip, one had Burkholderia cepacia in blood culture, and one had Klebsiella pneumonia with Enterobacter in urine and bloodstream. The rest of the six patients did not show any culture growth. Antibiotics were given according to institutional protocol.
Mean duration of ICU stay was 21.49 ± 18.14 days and that of hospital stay was 29.87 ± 19.91 days.
The overall mortality among the patients with DSC was 19% (12/63). The cause for mortality is expressed in [Table 6]. Independent t-test found factors associated with mortality. These factors have been mentioned in [Table 7] for reference. However, multivariate logistic regression revealed the need for preoperative MV (OR 42.82, 95% CI = 4.52- 406.03, p < 0.001) and development of postoperative sepsis (OR 20.07, 95% CI = 2.12–189.80, p = 0.002) as independent predictors of mortality.

Discussion
The first description of disproportionate cardiac and mediastinal cavity was made by Riahi et al in 1975.[1] Use in pediatric population was popularized by Ott et al[2] and in other studies.[4] The shift in the paradigm from palliative to total correction has led to rise in use of DSC. Jogi and Werner studied the detrimental effects of raised intrapericardial pressures while attempting premature sternal closure on transmural end-diastolic pressures of both the ventricles.[9] They seem to increase, leading to compensatory rise in atrial pressures, affecting atrial filling and, thus, falling end-diastolic volumes of the ventricles, translating into poor systemic perfusion. This has been demonstrated in echo-based[10] and catheter-based studies.[5] The reduced contractile force of myocardium in isovolumetric phase and inadequate coronary reserve due to poorly compliant ventricles has also been proposed.[11] However, keeping sternum open witnessed rise in cardiac index by 59% and in systolic blood pressures up to 18%.[12] [13] All this have led to increased applicability of DSC in various centers.
In our study the incidence of DSC was 34% which is comparable to the studies by Samir et al[14] (45%) and McElhinney et al[15](22%). TGA and hypoplastic left heart syndrome were the most common pathologies which led to DSC in previous studies.[8] [16] [17] [18] [19] ASO (41.27%) and TAPVC repair (26.98%) constituted the majority in our study.
The indications for DSC were multifactorial, with majority being myocardial edema, nonsurgical hemorrhage, and ECMO, which correlated well with other studies.[18] [19] [20] Lower incidences of sepsis and mortality were observed in patients managed by DSC, where decision was taken electively in the OR compared with those opened on emergency basis in the ICU.[14] [21] Therefore, the factors predicting DSC are essential to be kept in mind while management of DSC in the OR. In this study also, the decision for DSC was taken in the OR itself with no events of emergency sternal opening in the ICU.
The wide variation in weight and duration of DSC preclude a standard calculation, however, as an institutional policy for complex cardiac surgeries, we follow a total cumulative fluid balance of 75 to 100 mL/kg before attempted sternal closure. The importance of negative fluid balance has been highlighted in studies by Mills et al.[22]
The success of DSC could be demonstrated by significant improvement seen in hemodynamic and blood gas parameters as seen in [Tables 4] [5]. Also, the transient hemodynamic alterations around the sternal closure time, which improved after 12 hours of sternal closure ([Table 5]), correlated well with other studies.[22] [23] [24] However, the inotropic requirement and urine output remain unchanged. Horvath et al also demonstrated the decline in oxygen saturations; however, there was immediate discontinuation of neuromuscular blockade, which could have contributed to this effect.[24] In this study, the muscle relaxants were continued till 12 hours after the sternal closure; therefore, no sudden unexpected metabolic surges interfered with assessment.
There has also been postulated effects of complex pediatric cardiac surgeries on hypothalamic–pituitary–thyroid axis. The correction of complex lesions, institution of profound hypothermia for arrest of circulation, higher dose of vasopressor agents, and excess use of blood components in perioperative period have been proposed factors affecting this axis.[25] This effect is pronounced in pediatric age group, owing to immature central nervous system. The use of iodine containing ointment and adhesive drapes with iodine containing mediastinal irrigation may contribute further to iodine absorption from skin or pericardial cavity causing hypothyroidism. The trend in values of TT3, TT4 and TSH as summarized in results correlates well with the study by Kovacikova et al[25] and demonstrated the safety of using iodine-containing ointments and impregnated dressing materials without any effects of hypothyroidism in pediatric patients.
Sternal closure has been attempted by many techniques including skin approximation, application of sternal retractor, silicone sheet, mediastinal packs, sternal stent,[8] and bootlace technique.[26] Staged closure using a binder clip was described by Fuchigami et al.[27] Tanaka et al revealed a semisternal closure with bioresorbable osteosynthesis device.[28] This is not available at our center. We used the blood collection bag, which can be used as a polyurethane sheet for covering the open sternum in the management of DSC. It is readily available, sterile, transparent, cost-effective, and allows for prompt mediastinal inspection.
The assessment for timing of sternal closure was guided by hemodynamic stability, absence of significant arrhythmia, desirable diuresis achievement, optimal blood gas readings, acceptable ionotropic support, and adequate/improved ventricular contractility on echocardiographic assessment.
Sternal closure time did not significantly influence our rate of deep sternal wound infection. In this study, three patients (4.76%) developed mediastinitis. The incidence of mediastinitis due to delayed sternal closure ranges from 1.8% to 5.6% in various studies.[8] [14] [15] [19] Ozker et al revealed 10.5% incidence of mediastinitis with sternal closure times of 2.9 ± 2.3 days.[19] The lower incidence of mediastinitis in our study could be due to earlier closure of sternum in our patients with a mean of less than 2 days. Two of these three patients succumbed to septic shock with multiorgan failure. However, superficial SSI was seen in six cases (9.5%), which responded to conservative measures of topical saline irrigation, daily dressing under aseptic precautions, debridement, and secondary skin suturing, with none of them developing deep space infection. This SSI rate is almost 50% less than that reported in a retrospective study of STS database by Nelson-McMillan et al with 18.7% incidence.[29] Many authors have reported higher incidence of infection with a longer period of open chest.[7] [13] However, we believe that repeated episodes of sternal closure attempt after premature primary closure would influence the infection rate as was proposed by Harder et al.[30] There was also no case of delayed sternal wound dehiscence requiring re-fixation in our study.
There has been observed a four-fold rise in blood stream sepsis post DSC.[31] [32] Ozker[19] and colleagues reported 52.6% and Elassal et al[20] in their study described a sepsis rate of 54.1%. We, however, observed an incidence of 23.81% in this study which is less than the reported literature. The shorter duration of open sternum could have contributed to lower incidence. Also, there is an observed higher incidence of PD at 12.70% and tracheostomy at 17.46%, which helped us achieve better fluid balance and earlier weaning from mechanical ventilation, respectively. This contributed to earlier removal of invasive lines and a reduced incidence of sepsis in our study. We did not use modified ultrafiltration routinely in the operating room at our center, hence, we had a low threshold for utilizing PD postoperatively without any observed morbidity. On culture growth, the microbial flora consisted most commonly of Gram negative group of bacteria which correlates well with the published literature.[19] [21] [33]
We observed a mortality of 19%, which is similar to what has been reported in previous studies by many authors.[8] [17] [19] [20] The presence of preoperative MV was found to be contributory to mortality (p < 0.001) as was found in other studies.[14] [20] Preoperative sepsis (p = 0.066) and inotropic support (p = 0.75) did not reach statistical significance as contributor for mortality. Samir et al[14] in their study of 312 neonates found that preoperative inotropic support was not related with mortality as was seen in this study. Sierra et al[34] found that risk adjustment for congenital heart surgery (RACHS-1) score > 3 predicts mortality which corroborated well with our study (p < 0.001). Longer ACC time translates into a complex cardiac surgery, which has been found to be associated with mortality.[17] [20] [34] [35] Similar finding was observed in our study (p < 0.001), however, duration of CPB was not found to be related to mortality (p = 0.94). In addition, the postoperative factors such as requirement of re-explorations (p < 0.001), duration of DSC (p < 0.001), duration of postoperative MV (p < 0.001), and development of culture-proven sepsis (p = 0.002) and mediastinitis (p = 0.03) contributed significantly to mortality, as has been corroborated by other studies.[8] [14] [17] [34] However, on multivariate analysis, the factors independently contributing to mortality were found to be the need for preoperative MV and development of postoperative sepsis.
#
Study Limitations
This is a single center study with a limited study population. It involved three different cardiac surgeons with comparable surgical experience, however, there could be possible variations among intraoperative decision-making for DSC. The overall results and mortality may differ accordingly.
#
Conclusion
DSC is being increasingly utilized in adjunct to complex pediatric cardiac surgeries. The decision to manage with DSC should be taken in the OR primarily to avoid complications of emergency sternal opening in the ICU. The improved hemodynamic and metabolic profile with avoidance of mediastinal compression forms the background of DSC. Early sternal closure should be considered on the basis of cardiovascular function and/or resolution of primary indication for DSC.
