11. MANAGEMENT TYPE OF DELIVERY Vaginal delivery:Vaginal delivery: SpontaneousSpontaneous Partial breech extractionPartial breech extraction Total breech extractionTotal breech extraction Cesarean deliveryCesarean delivery

12. TYPES OF VAGINAL BREECH DELIVERY Spontaneous breech (rare): No manipulation of the infant is necessary, other than supporting the infantSpontaneous breech (rare): No manipulation of the infant is necessary, other than supporting the infant Partial breech extraction: Fetus descend spontaneously to where umbilicus is at the vaginal introitus; then, the fetus is extracted completelyPartial breech extraction: Fetus descend spontaneously to where umbilicus is at the vaginal introitus; then, the fetus is extracted completely Total breech extraction: The entire body is extracted. This is indicated only if there is evidence of fetal distress unresponsive to routine maneuvers and a cesarean delivery is not possible.Total breech extraction: The entire body is extracted. This is indicated only if there is evidence of fetal distress unresponsive to routine maneuvers and a cesarean delivery is not possible.

13. CONDITIONS ARE UNFAVORABLE FOR BREECH DELIVERY Fetus weight > 3500 gFetus weight > 3500 g Unfavorable pelvis – Breech delivery does not allow sufficient time for molding of the fetal head; thus, a platypelloid or android pelvis decreases ability fetal head to navigate maternal pelvisUnfavorable pelvis – Breech delivery does not allow sufficient time for molding of the fetal head; thus, a platypelloid or android pelvis decreases ability fetal head to navigate maternal pelvis Hyperextension of the head – increases risk of cervical spine injuryHyperextension of the head – increases risk of cervical spine injury Footlings- incidence of umbilical cord prolapse increases with coiling of the umbilical cord around the legs of the fetusFootlings- incidence of umbilical cord prolapse increases with coiling of the umbilical cord around the legs of the fetus

14. MORTALITY/MORBIDITY Increased birth trauma: As duration of umbilical cord compression increases → deliver the infant more rapidly → increasing birth traumaIncreased birth trauma: As duration of umbilical cord compression increases → deliver the infant more rapidly → increasing birth trauma Decreased birth weight may result from preterm delivery/growth restrictionDecreased birth weight may result from preterm delivery/growth restriction Incidence of prolapsed umbilical cord depends on type of breech presentation : Footling 17%, Complete 5%, Frank 0,5%Incidence of prolapsed umbilical cord depends on type of breech presentation : Footling 17%, Complete 5%, Frank 0,5%
