44 Emergency Childbirth

45 Developing Fetus Placenta Amniotic Sac Bag of waters Umbilical cord Fetus

46 Labor z1st stage: Onset of contractions to dilation of cervix z2nd stage: Complete dilation of cervix to delivery of baby z3rd stage: Delivery of baby to delivery of placenta

47 Signs of Imminent Delivery zCrowning zRupture of Amniotic Sac zNeed to bear down zSensation of needing to move bowels zContractions y1 to 2 minutes apart yRegular yLasting 45 to 60 seconds

48 Delivery zPlace gloved hand on presenting part to prevent explosive delivery zOn delivery of head, suction mouth then nose

49 Delivery zGently guide babys head down to deliver upper shoulder zGently guide babys head up to deliver lower shoulder zGently assist with delivery of rest of baby; Do NOT pull zNote time of delivery of baby

50 Delivery zControl slippery baby during delivery ySupport head, shoulders, feet yKeep head lower then feet to facilitate drainage of secretions from mouth zDry baby zKeep baby warm
