Grandmultiparity--trends and complications: a study in two hospital settings.
Pregnancy after the fifth delivery is viewed with anxiety, especially by obstetricians in developing countries working with inadequate facilities. High parity is still common with serious consequences to the fetus, the mother, the family and society. In the last 40 years, non-governmental, national and international efforts have been made to reduce fertility rates. We therefore intended to determine the trend in the grandmultiparity rates from 1 January 1987 to 31 December 1994 in the South Western part of Nigeria. The obstetric performance of these grandmultiparae in two different settings were to be compared. This was a retrospective, case-note analysis of all the grandmultiparae delivered at the University College Hospital (UCH) (Group A) and the Oluyoro Catholic Hospital (OCH) (Group B), both in Ibadan city. The former is a tertiary health care centre while the latter is a secondary centre. The socio-clinico-demographic characteristics of these patients were collated and analysis and comparison performed using EPI-INFO software. In Group A, 828 grandmultiparae were seen among 9215 deliveries, a rate of 8.99% (10.90% in 1987 to 3.36% in 1994). In Group B, there were 1940 cases among 22 587 deliveries, i.e. 8.59% (12.75% to 6.07%), respectively. The modal age group was 31-35 years, and women above 35 years formed one-third of cases. The parity group 5-7 was the most frequent in both groups (91.6% vs. 94.9%). Only two mothers (both in group B) had parity above 10. Booked patients formed a larger percentage in Group B than in Group A (85.8% vs. 69.7%, respectively). In Group B 85.9% had spontaneous vertex delivery as opposed to 66.3% in Group A. Caesarean section was the mode of delivery in 9.0% and 24.2% in Groups B and A, respectively. Equal percentages had breech delivery. The modal birth weight was 2.51-3.00 kg in both groups. Macrosomic babies formed 3.7% in Group A and 2.4% in Group B, while low birth weight babies formed 17.7% and 11.7% in Groups A and B, respectively. The crude perinatal death ratio was 123/1000 in Group A and 68/1000 in Group B. Antepartum haemorrhage, anaemia and premature rupture of membranes in Group A and anaemia, hypertension and antepartum haemorrhage in Group B were the most common pregnancy complications noted. In labour, abnormal lie/presentation, prolonged labour and premature labour in Group A and abnormal lie/presentation, antepartum haemorrhage and birth asphyxia in Group B formed the majority of the complications. The most common puerperal complications were primary postpartum haemorrhage, wound/genital sepsis in Group A and anaemia and primary postpartum haemorrhage in Group B, respectively. Maternal death ratio was 10.85/100 000 total deliveries in Group A and 35.42/100 000 in Group B. High parity is still common in developing countries, although the incidence is declining, with rates of 3.4% and 6.1% of total deliveries in Groups A and B, respectively. More patients are delivered per abdomen at UCH compared to OCH. The perinatal mortality rate is higher at UCH than OCH but the maternal mortality rates follow the reverse. Recommendations are made concerning the reduction in high parity rates and its associated complications.
