While I wouldn't consider them all "emergencies", I have seen and dealt with a number of unusual situations ie: cord around the neck, quintuple nuchal cord, broken/torn umbilical cord, cord knots, velamentous cord insertion, abrupted placenta, cervical lacerations, retained placenta, placenta previa, placenta accreta, Chronic Hystiocytic Intervillositis, IUGR, surprise twins, unexpected breech delivery, shoulder dystocia, compound presentation, transverse lie at term, preterm labor, chorio-amnionitis, oligohydramnios, polyhydramnios, Thrombophlebitis, pre-ecclampsia, HELLP syndrome, PUPPPS, gestational diabetes, ICP (Intrahepatic Cholestasis of Pregnancy), Rh sensitization, hematomas, Preganancy Induced Hypertension, fetal distress, newborn needing resuscitation, respiratory distress, birth asphyxia, MAS (Meconium Aspiration Syndrome), SGA (small for gestation age) infant, GBS sepsis, hypoglycemic infant, gastroschisis, Hypoplastic Left Heart Syndrome, various birth defects/malformations, postpartum psychosis, 3rd and 4th degree lacerations, maternal hemmorhage and shock. Some of these were handled at home, others were transported to the hospital appropriately, all with healthy results for both mom and baby.
