The results of a retrospective study involving 622 twin-pairs born over an 18-month period among 17,726 births at the University of Ilorin Teaching Hospital, Ilorin, Nigeria, are presented with particular reference to four variables: birthweight, presentation, parity, and intertwin delivery time interval. The twinning incidence was 35.1 per 1000. Monozygous and dizygous rates are 7 and 28 per 1000, respectively. Overall perinatal mortality (PNM) was 15.5%. Mortality was higher in second than in first twin (19.5% vs. 11.6%), and consistently higher when divided into birthweight groups. Corrected PNM increased with breech presentations: 16.3% in breech:breech compared with 3.9% in vertex:vertex presentations. The twinning rate increased with parity; PNM is low in parity 1, of little variation in birth-ranks 2-5, and high in para 6 and above. Delivery of the second twin within 15 min seems optimal, giving a corrected PNM 3.6% in contrast to rates of 10.1%, 14.0% and 19.1%, respectively when delivery occurred between 16 and 30, 31 and 60 and greater than 60 min, respectively. Prevention of preterm delivery, increased use of cesarean section delivery for malpresentation, active management of delivery of second twin within an optimal time of 15 min, and family planning are suggested in order to decrease twin PNM. :Results of a retrospective study involving 622 pairs of twins born over an 18-month period among 17,726 births at the University of Ilorin Teaching Hospital in Ilorin, Nigeria, are presented with particular reference to 4 variables: birthweight, presentation, parity, and intertwin delivery time interval.

Prevention of pre-term delivery, increased use of cesarian section delivery for malpresentation, active management of delivery of 2nd twin within an optimal time of 15 minutes and family planning are suggested in order to decrease twin PNM.

:一项回顾性研究的结果涉及到18个月内在尼日利亚伊洛林市伊洛林大学教学医院的17726例出生中的622对双胞胎,其中特别提到了四个变量:出生体重,出诊率,胎次和相互交织的时间间隔。孪生发生率为35.1 / 1000。单合子和二合子率分别为7和28/1000。围产期总死亡率(PNM)为15.5%。第二胎的死亡率高于第一胎的死亡率(19.5%比11.6%),分成出生体重组时,死亡率始终较高。校正后的PNM随臀位的显示而增加:臀位:臀位的显示为16.3%,而顶点:顶点表达的为3.9%。孪生率随同位率的增加而增加。 PNM在等位1处较低,在出生等级2-5中几乎没有变化,而在第6段及以上位置较高。在15分钟内分娩第二胎似乎是最佳的,经校正的PNM为3.6%,而分别在16和30、31和60之间以及大于60分钟时分娩的比率分别为10.1%,14.0%和19.1%。 。建议减少早产,增加剖宫产用于不当行为的使用,在15分钟的最佳时间内积极管理第二胎的分娩以及计划生育,以减少双胎PNM。
