The United States is with 37,451 home births in 2014 the country with the largest absolute number of home births among all developed countries. The purpose of this study was to examine the occurrence and risks of a 5-minute Apgar score of zero and neonatal seizures or serious neurologic dysfunction in women with a history of prior cesarean delivery for planned home vaginal birth after cesarean (VBAC), compared to hospital VBAC and hospital birth cesarean deliveries for term normal weight infants in the United States from 2007-2014. We report in this study outcomes of women who had one or more prior cesarean deliveries and included women who had a successful vaginal birth after a trial of labor after cesarean (TOLAC) at home and in the hospital, and a repeat cesarean delivery in the hospital. We excluded preterm births (<37 weeks) and infants weighing under 2500 g. Hospital VBACS were the reference. Women with a planned home birth VBAC had an approximately 10-fold and higher increase in adverse neonatal outcomes when compared to hospital VBACS and hospital repeat cesarean deliveries, a significantly higher incidence and risk of a 5-minute Apgar score of 0 of 1 in 890 (11.24/10,000, relative risk 9.04, 95% confidence interval 4-20.39, p<.0001) and an incidence of neonatal seizures or severe neurologic dysfunction of 1 in 814 (Incidence: 12.27/10,000, relative risk 11.19, 95% confidence interval 5.13-24.29, p<.0001). Because of the significantly increased neonatal risks, obstetric providers should therefore not offer or perform planned home TOLACs and for those desiring a VBAC should strongly recommend a planned TOLAC in the appropriate hospital setting. We emphasize that this stance should be accompanied by effective efforts to make TOLAC available in the appropriate hospital setting.
2014年,美国有37451例家庭分娩,在所有发达国家中家庭分娩的绝对数量最多。本研究的目的是,与美国2007 - 2014年足月正常体重婴儿的医院瘢痕子宫阴道试产(VBAC)及医院剖宫产相比,调查有剖宫产史且计划在家进行瘢痕子宫阴道分娩(VBAC)的女性中,5分钟阿氏评分0分、新生儿惊厥或严重神经功能障碍的发生情况及风险。我们在本研究中报告了有一次或多次既往剖宫产史的女性的结局,包括在家和在医院剖宫产术后经阴道试产(TOLAC)成功的阴道分娩女性,以及在医院进行再次剖宫产的女性。我们排除了早产(<37周)和体重低于2500 g的婴儿。以医院VBAC作为对照。计划在家进行VBAC分娩的女性,与医院VBAC及医院再次剖宫产相比,不良新生儿结局增加约10倍甚至更高,5分钟阿氏评分0分的发生率和风险显著更高,为890例中有1例(11.24/10000,相对风险9.04,95%置信区间4 - 20.39,p<0.0001),新生儿惊厥或严重神经功能障碍的发生率为814例中有1例(发生率:12.27/10000,相对风险11.19,95%置信区间5.13 - 24.29,p<0.0001)。由于新生儿风险显著增加,产科医护人员不应提供或实施计划在家的TOLAC,对于那些希望进行VBAC的女性,应强烈建议在合适的医院环境中进行计划TOLAC。我们强调,这一立场应伴随在合适的医院环境中有效开展TOLAC的努力。
