Breech Presentation
Considerations
-
↑ risk of maternal mortality, morbidity, & complications (infection, perineal trauma, hemorrhage)
-
↑ risk of fetal complications:
-
Preterm delivery
-
Birth trauma
-
Major congenital anomalies
-
Umbilical cord prolapse
-
Hyperextension of the head
-
Spinal cord injuries with deflexion
-
Arrest of after-coming head
-
Intrapartum asphyxia
-
Intrapartum fetal death
-
-
Considerations of external cephalic version if performed
-
Recommended mode of delivery is cesarean section but vaginal delivery can be attempted with term singleton with adequate pre-planning (Canadian guidelines 2009)
-
Pregnancy considerations (difficult intubation, aspiration, ↓ time to desaturation, aortocaval compression, 2 patients)
Management
-
Analgesia for labor:
-
Early epidural if possible
-
The patient MUST NOT PUSH IN 1st stage of labor → might push a lower extremity through her partially dilated cervix, which may result in fetal head entrapment
-
-
Anesthesia for vaginal breech delivery:
-
Delivery preferred in the OR should emergency cesarean be required → always be ready to convert to GA!
-
Epidural strongly recommended
-
Very high risk including:
-
Umbilical cord compression
-
Fetal head entrapment
-
-
-
Anesthesia for cesarean delivery:
-
Neuraxial or GA
-
Possible need for uterine relaxation, have nitroglycerin available
-
May require larger incision or a vertical incision
-
-
Fetal head entrapment:
-
Nitroglycerin IV 100-400mcg OR nitroglycerin SL 400-800mcg
-
Likely need STAT GA: RSI (propofol/succinylcholine) & start 2-3 MAC of volatile to relax uterus
-
Be ready to support hemodynamics, control hemorrhage
