目的:探讨新生儿窒息对新生儿臂丛神经损伤(NBPP)发生的影响程度。方法:采集102例NBPP病例资料和2 937例正常新生儿资料,对2组资料中难产、手术助产、出生体重≥4 000 g及新生儿窒息等因素采用完全随机设计的χ2检验,并进一步用单因素和多因素logistic模型分析。结果:难产、手术助产、新生儿出生体重≥4 000 g和新生儿窒息史,NBPP病例组与对照组之间的差异均有统计学意义(P〈0.001);遭遇难产、手术助产(胎吸、产钳、2种以上方式)、出生体重≥4 000 g和有窒息史的新生儿患NBPP的风险分别增加约28倍(OR=29.0,95%CI=13.1~64.5),17~150倍(OR=18.6,95%CI=7.4~46.9;OR=16.9,95%CI=4.9~58.9;OR=151.7,95%CI=73.2~207.2),41倍(OR=42.4,95%CI=19.7~91.3)和130倍(OR=131.8,95%CI=52.8~328.9)。结论:新生儿窒息与难产、手术助产(胎吸、产钳)和新生儿出生体重≥4 000 g一样,是NBPP发生的高危因素。
Objective: To investigate the effects of neonatal asphyxia on the incidence of neonatal brachial plexus palsy(NBPP).Methods: Data of 102 patients with NBPP and of 2 937 healthy neonates were collected.Factors including dystocia,surgery-assisted delivery,birth weight ≥ 4 000 g,and neonatal asphyxia in these 2 groups were analyzed by a completely randomly designed χ2 test.The data were further analyzed with univariate and multivariate logistic models.Results: Between the NBPP and control groups,significant differences were observed for dystocia,surgery-assisted delivery,birth weight ≥ 4 000 g,and neonatal asphyxia history(P0.001).The risks of NBPP increased by 28.0 times(odds ratio =29.0,95% confidence interval =13.1~64.5) among neonates who had dystocia,by 15.9,17.6 and 150.7 times respectively in those born by means of surgery-assisted delivery(with the help of obstetric forceps,OR=16.9,95% CI=4.9~58.9;with vacuum assistance,OR=18.6,95% CI=7.4~46.9;and with 2 or more methods,OR=151.7,95% CI=73.2~207.2),by 41.4 times in those with birth weight ≥ 4 000 g(OR=42.4,95% CI=19.7~91.3),and by 130.8 times in those with neonatal asphyxia history(OR=131.8,95% CI=52.8~328.9).Conclusion: Neonatal asphyxia,dystocia,vacuum-assisted or forceps delivery,and neonatal birth weight ≥ 4 000 g are risky factors for NBPP.
