Decision-caesarean delivery interval in a Nigerian university hospital: implications for maternal morbidity and...

This is a 5-month prospective study to determine the decision emergency caesarean delivery interval in a Nigerian tertiary hospital, the factors responsible for the delays and the consequent maternal and perinatal complications. One hundred and thirty-four emergency caesarean deliveries were analysed and the main indications were failure to progress/ prolonged labour (35.4%), previous caesarean-section/failed trial of scar (27.9%), cephalopelvic disproportion (26.8%), fetal distress (19.5%), pre-eclampsia/eclampsia (15.3%) and obstructed labour/ruptured uterus (14.7%). The mean decision-caesarean delivery interval was 4.4 +/- 4.2 (SD) hours (range 0.5-26 hours), median 3.2 hours and mode 2 hours. Bottlenecks within the maternity unit were responsible for delays in 31.7% of cases. Unavailability of paediatrician (19.6%), non-availability of anaesthetic coverage (13.6%), unreadiness of the operation theatre (11.9%) and seeking second opinion (6.4%) were other major causes of delay. There were 15 perinatal deaths, five of whom were directly linked to the delays i.e. a perinatal mortality rate of 3.7%. Four maternal deaths were directly attributable to delay, a maternal mortality rate of 3%. Other direct consequences of the delays were severe haemorrhage (10.3%), uterine rupture (2.3%) and disseminated intravascular coagulopathy (1.5%). Suggestions on how to minimise delays in emergency services and overall improvement in quality assurance control are discussed.
