Delivery of the impacted head of the fetus at caesarean section after prolonged obstructed labour: a randomised comparative study of two methods.

Obstructed labour is a common obstetric complication in Nigeria associated with poor fetal and maternal outcome. Delivery of the fetus at caesarean section is always difficult, especially if the fetal head is impacted in the pelvis. The mode of delivery at caesarean section may occasionally compound the morbidity associated with obstructed labour. The purpose of this study was to examine and compare the morbidity and mortality associated with two methods of delivery of the impacted fetal head at caesarean section for obstructed labour (the push method and the pull (reverse breech) method). This study is a prospective study of cases of obstructed labour admitted into the labour ward of Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife between 1 June 1998 and May 31 2000. One hundred and eight women with obstructed labour at term with live fetus undergoing caesarean section were assigned randomly to either of the methods of admission. The maternal and fetal outcomes were analysed and compared between groups. Patients in the push group had statistically significant higher rates of maternal morbidity (longer operation time, more blood loss, extension of uterine incision, endometritis, longer hospital stay and higher hospital bills) than the pull method (P < 0.05). Also the fetal morbidity was worse in the push group. The 'pull' method of delivery of impacted fetal head at caesarean section for obstruction is safer and faster than the 'push' method.
