入选标准
- •English-speaking
- •>= 36 weeks gestation
- •Singleton pregnancy
- •Vertex presentation
- •No contraindication to a vaginal delivery
- •Meets at least one study criteria for prolonged labor:
- •cervical dilation <6 cm after ≥8 hours with ruptured membranes and receiving oxytocin OR
- •cervical dilation >=6 cm and <1 cm dilation change over ≥2 hours with ruptured membranes and receiving oxytocin
排除标准
- •Severe preeclampsia: as patients will be receiving magnesium and possibly labetalol for hypertension control
- •Receiving other beta blocker
- •Maternal heart rate < 70 beats per minute, systolic blood pressure <90 mmHg, or diastolic blood pressure <50 mmHg on two sets of vital signs in the 1 hour prior to study drug administration: given that bradycardia and hypotension are possible side effects of propranolol
- •History of any form of asthma: as this is a contraindication to beta blocker use
- •Diabetes requiring insulin in labor: given the potential risk of neonatal hypoglycemia in the neonate
- •Any cardiac condition for which β blockade is contraindicated (cardiogenic shock, sinus bradycardia, and greater than first degree heart block)
- •Known hypersensitivity to propranolol
- •Intrauterine fetal demise since different labor protocols are used in these women
- •Major fetal congenital anomaly since rate of cesarean may be inherently different in these women, unrelated to labor
