The purpose of this study was to determine the incidence of mortality and morbidity of the very-low-birthweight infant (< 1,500 g) in breech presentation based on mode of delivery and birthweight. A retrospective chart review of 1,009 infants who were in breech presentation at the time of delivery between January 1, 1990 and December 31, 1995 at the First Department of Obstetrics and Gynecology of Semmelweis Medical School in Budapest, Hungary. Data collected included birthweight, mode of delivery, pregnancy complications and neonatal mortality and morbidity. Comparison of groups was made based on mode of delivery, and data were analyzed using Fisher's exact test and chi-square analysis. For those infants weighing less than 1,500 g at birth, vaginal delivery was associated with higher mortality than for those delivered abdominally (73.8% vs. 37.7%, P < 0.001). There was no significant difference in survival for those infants weighing 1,500 g or more. Regarding morbidity, in those infants weighing less than 1,500 g, vaginal delivery was associated with a higher incidence of 1 min Apgar below 4 (21.7% vs. 5.2%, P < 0.001), a higher incidence of 5-min Apgar scores below 4 (11.6% vs. 1.2%, P < 0.001), a higher incidence of grade III or grade IV IVH (18.8% vs. 3.5%, P < 0.001) and a higher incidence of necrotizing enterocolitis (5.8% vs. 0.6%, P < 0.05). There is an increased incidence of mortality and morbidity for the VLBW breech infant delivered vaginally. Cesarean delivery may improve outcome for these infants.
本研究的目的是根据分娩方式和出生体重确定臀位极低出生体重儿(<1500g)的死亡率和发病率。对1990年1月1日至1995年12月31日在匈牙利布达佩斯塞梅尔维斯医学院第一妇产科分娩时为臀位的1009例婴儿进行回顾性病历审查。收集的数据包括出生体重、分娩方式、妊娠并发症以及新生儿死亡率和发病率。根据分娩方式对各组进行比较,并使用Fisher精确检验和卡方分析对数据进行分析。对于出生时体重小于1500g的婴儿,阴道分娩的死亡率高于剖宫产分娩(73.8%对37.7%,P<0.001)。体重1500g或以上的婴儿在生存率方面无显著差异。关于发病率,在体重小于1500g的婴儿中,阴道分娩与1分钟阿氏评分低于4分的发生率较高(21.7%对5.2%,P<0.001)、5分钟阿氏评分低于4分的发生率较高(11.6%对1.2%,P<0.001)、III级或IV级脑室内出血的发生率较高(18.8%对3.5%,P<0.001)以及坏死性小肠结肠炎的发生率较高(5.8%对0.6%,P<0.05)相关。阴道分娩的极低出生体重臀位婴儿的死亡率和发病率增加。剖宫产可能改善这些婴儿的结局。
