Abstract
The novel coronavirus disease 2019 (COVID-19) is spreading fast and is affecting the
clinical workers at much higher risk than the general population. Little is known
about COVID-19 effect on pregnant women; however, the emerging evidence suggests they
may be at high risk of asymptomatic disease. In light of projected shortage of personal
protective equipment (PPE), there is an aggressive attempt at conservation. In obstetrics,
the guidelines on PPE use are controversial and differ among hospitals, globally,
as well as nationally. The centers for disease control and prevention (CDC) recommend
using N95 respirators, which are respirators that offer a higher level of protection
instead of a facemask for when performing or present for an aerosol-generating procedures
(AGP). However, the second stage of labor is not considered an AGP. The second stage
of labor can last up to 4 hours. During that time, labor and delivery personnel is
in close contact to patients, who are exerting extreme effort during and frequently
blow out their breath, cough, shout, and vomit, all of which put the health care team
at risk, considering that COVID-19 transmission occurs through aerosol generated by
coughing and sneezing. The CDC and the American College of Obstetricians and Gynecologists
(ACOG) do not provide clarification on the use of N95 during the second stage. We
recommend that labor and delivery personnel have the utmost caution and be granted
the protection they need to protect themselves and other patients. This includes providing
labor and delivery personnel full PPE including N95 for the second stage of labor.
This is critical to ensure the adequate protection for health care workers and to
prevent spread to other health care workers and patients.
Key Points
-
Second stage of labor exposes providers to aerosol.
-
COVID-19 risk during second stage of labor is high.
-
N95 should be used during second stage of labor.
