Figure 1.Mode of delivery of women.
As shown in Figure 1, half of the women (11, 50.0%) delivered through elective cesarean section, 7 (31.8%) had emergency cesarean section, while 4 women (18.2%) delivered through spontaneous vaginal delivery. In total, 32 neonates (47.8%) were female, while 35 (52.2%) were male.

As shown in Table 1, the majority of the women (12, 54.6%) were in the 30–34 years age group and the mean maternal age was 31.23 ± 4.48 years with a range of 20–40 years. The majority of the women (16, 72.7%) were multiparas, while 4 (18.2%) were primiparas. More than half (13, 59.1%) of the women delivered preterm with a mean gestational age of 35.82 ± 2.24 weeks. The minimum gestational age was 31.5 weeks, while the maximum was 40 weeks. Secondary education is the commonest (10, 45.5%) form of education attained by women with the majority (20, 90.9%) being Christian.
Most of the women (16, 72.7%) booked for antenatal care in the facility and 40.9% (9) of those who carried their pregnancy beyond 36 weeks belonged to this group.
Total deliveries and incidence of HOM pregnancies during the period of review.
| Year | Total delivery | HOM | Incidence of HOM (%) |
|---|---|---|---|
| 2012 | 2396 | 2 | 0.1 |
| 2013 | 2760 | 4 | 0.1 |
| 2014 | 2174 | 6 | 0.3 |
| 2015 | 2295 | 4 | 0.2 |
| 2016 | 2377 | 6 | 0.3 |
| Total | 12,002 | 22 | 0.2 |
HOM: higher-order multiple.
As seen in Table 2, the year 2012 had the lowest point prevalence of HOM pregnancies, while the years 2014 and 2016 recorded the highest incidence number of HOM pregnancy deliveries.
Booking status and perinatal outcome.
| Booking status | Perinatal outcome | |
|---|---|---|
| Survived (%) | Mortality (%) | |
| Unbooked (HOM) | ||
| 3 (triplet) | 15 (22.4) | 3 (4.5) |
| 4 (quadruplet) | 0 (0.0) | 0 (0.0) |
| Total | 15 (22.4) | 3 (4.5) |
| Booked (HOM) | ||
| 3 (triplet) | 42 (62.7) | 3 (4.5) |
| 4 (quadruplet) | 4 (6.0) | 0 (0.0) |
| Total | 46 (68.7) | 3 (4.5) |
HOM: higher-order multiple; OR: odds ratio; CI: confidence interval.
As shown in Table 3, the total number of live births was 67 with a perinatal survival rate of 85.1%. Being booked is associated with better neonatal outcomes although not significant (OR = 3.06, 95% CI: 0.55–16.83, p = 0.197). The perinatal mortality rate was 89.6 per 1000 total births with an equal frequency of neonatal death on both booked and unbooked women. Table 3 also shows the number of fetuses among the HOM pregnant women, and 63 (94.0%) were triplets from 21 women (95.5%), while 4 (6.0%) quadruplet fetuses were from one woman representing 4.6%.

HOM: higher-order multiple
As seen in Table 4, preterm labor occurred in 5 (31.3%) women. Anemia was the commonest postpartum complication (6, 46.2%). Preeclampsia and premature rupture of membranes each occurred in 18.8% of women. A perineal tear was the complication during delivery. Other noted postpartum complications include postpartum hemorrhage (4, 30.8%), spinal headache (2, 15.4%), and puerperal sepsis (1, 7.7%). Uterine atony accounted for 75% of postpartum hemorrhage, while a case (25%) was due to perineal tear. No maternal mortality was recorded.

As shown in Table 5, the total number of neonates delivered was 67; 94% (63) of these were from triplet gestation, while 6% (4) were from quadruplet conception. Most of the fetuses (35, 52.2%) delivered weighed between 2.0 and 2.49 kg. The mean birth weight of the babies was 2.14 ± 0.35 kg with a minimum weight of 1.3 kg and a maximum weight of 3.0 kg. In total, 48 babies (71.6%) had an Apgar score of ⩾7 in 1 min, with only 9 (13.4%) having an Apgar score of ⩽ 3 in 1 min. The Apgar score of the fetuses at 5 min showed that the majority of the fetuses (55, 82.1%) had an Apgar score of ⩾7. Only 6 (9.0%) had Apgar scores of ⩽3 at 5 min. Out of the 67 births recorded, 61 (91.0%) were live births, while 6 (9.0%) were perinatal deaths. The perinatal mortality of HOM pregnancies was 89.8 per 1000 live births (not in table). Three (50%) of the perinatal mortality in this study occurred in triplets weighing between 1.3 and1.5 kg who suffered early neonatal death. The remaining three perinatal deaths resulted from stillbirths recorded in unbooked patients who presented in advanced labor who had a spontaneous vaginal delivery.
