Ans. is a, b and c i.e. Intracranial hemorrhage; Atlanto axial dislocation; and Asphyxia The risk of fetal moality and morbidity are greatly increased in the vaginal breech delivery Fetal moality is least in frank breech and maximum in footling presentation (as the chances of cord prolapse are more). Gynaecoid and anthropoid pelves are ourable for the after coming head. The fetal risk in multipara is no less than that of primigravida because of increased chances of cord prolapse associated with flexed breech which occurs in multipara. The main causes of increased perinatal moality and morbidity in breech are : Prematurity Increased incidence of Congenital anomalies. Bih asphyxia : -- Due to cord prolapse or cord compression. -- Due to prolonged delivery and delay in the after coming head. Bih trauma due to rough handling during delivery and failure to use the femoropelvic grip : Intracranial hemorrhage due to uncontrolled delivery of the head and rupture of the veins of Galen or tentorial or falx tears. Skull fractures can also occur. -- Fracture dislocation of cervical veebra, atlantoaxial dislocation and occipital diastasis. Cervical and brachial plexuses injuries, including Erb's palsy. Complete transection of spinal cord. -- Sternocleidomastoid hematoma and later toicollis. Rupture liver and spleen. Fracture of femur, clavicle or humerus. Damage to the fetal adrenals. Traumatised pharynx due to the obstetrician's finger. Ans. is a, c and d i.e. Intracranial hemorrhage; Atlanto axial dislocation; and Asphyxia
