-anti-diuretic
-water intoxication= convulsions, coma, death
Uterine rupture (rare)
Dose an oxytocin infusion
Oxytocin infusion start at 1mUnit/minute and increase by 1mUnite/min every 30min until target contraction rate attained

25% women
affects 1/2000 births

When should mother be tested for GBS?
within 5 weeks of delivery
Tx of mothers GBS is when
IV abx during delivery
