SARS-CoV-2 in Pregnancy: A Comprehensive Summary of Current Guidelines
2. Experimental Section
- Prenatal and antepartum care (See Table 2): Reviewed guidelines support some form of screening of pregnant patients depending on symptoms and exposure, use of telehealth is encouraged for prenatal visits, while limiting face to face visits and ultrasounds only to those that are medically necessary. Prenatal appointments, lab work, and ultrasounds should be scheduled on the same day if possible. All ultrasound equipment and patient rooms should be appropriately cleaned after each use. The use of antenatal corticosteroids for fetal lung maturation can be continued till 34 weeks gestation, but the use of steroids in the late preterm period, >34 0/7 weeks gestation remains controversial.
- Intrapartum care (See Table 3): Reviewed guidelines recommend a designated area within the unit to care for SARS-CoV-2 positive pregnant patients or Person under investigation (PUI). Timing and mode of delivery should follow routine obstetric indications. Cesarean section (CS) should be reserved for obstetric indications only; infection with SARS-CoV-2 is not an indication for cesarean delivery unless there is acute decompensation of mother or fetus. Only one consistent asymptomatic support person is allowed to be present at time of delivery. Patients and healthcare workers should be appropriately gowned, gloved, and have protective face masks; specifically, N95 should be used for aerosol generating procedures such as forceful expiration during pushing, use of oxygen for intrauterine resuscitation, or intubation. Use of operative delivery to shorten the second stage of labor can be considered for routine obstetric indications. There is no contraindication to regional or general anesthesia if indicated, but appropriate personal protective equipment (PPE) use is encouraged.
- Postpartum care (See Table 4): Reviewed guidelines encourage early discharge from the hospital, one day for vaginal delivery and two days for cesarean delivery. This limits face to face exposure and increases bed availability. Separation of mother and baby or discouraging breastfeeding are not advised, unless the mother is acutely ill. However, mothers are encouraged to (1) practice respiratory hygiene during feeding, (2) wear a mask, (3) wash hands before and after touching the baby, and (4) routinely clean and disinfect surfaces they have touched. If breastpumping is used, all equipment should be cleaned thoroughly before and after each use. Postpartum visits should be performed over telehealth, unless face to face visit is essential to management.
