改良头位分娩评分法在头位难产中应用研究

Research on the Application of Modified Scoring Method for Head Delivery in Diagnosis of Head-position Dystocia

目的:探讨改良头位分娩评分法用于识别初产妇头位难产的可行性和临床价值。方法:对420例足月分娩初产妇应用改良头位分娩评分法进行适时评分,采取相应措施,选择正确分娩方式进行分娩。结果:420例孕妇中经阴道分娩为313例(74.5%),剖宫产的为107例(25.5%);新生儿窒息的发生率为5.2%(22/420);其中改良评分在80分以上的产妇经阴道分娩率为95.7%(267/279),剖宫产率为4.3%(12/279),评分在80分以下的产妇经阴道分娩率为67.4%(95/141),剖宫产率为32.6%(46/141),两者间比较,差异具统计学意义(P<0.05)。结论:改良头位分娩评分可及时地、准确地判断头位难产,便于医生作出正确选择,减少新生儿窒息的发生。

Objective：To investigate the feasibility and clinical practice of modified scoring method for head delivery in diagnosis of head-position dystocia.Methods：420 cases of unipara were graded by modified scoring method and under taken relevant measures.Results：In 420 gravidas,313 cases （74.5%） were deliveried through vagina and other 107 cases （25.5%） were deliveried by caesarean section.The rate of asphyxia neonatorum was 5.2% （22/420）.In the gravidas whose grades were above 80,the rate of delivery through vagina and caesarean section was 95.7% （267/279） and 4.3% （12/279）,respectively.In the gravidas whose grades were blew 80,the rate of delivery through vagina and caesarean section was 67.4% （95/141） and 32.6% （46/141）,respectively.The difference was significant （P0.05）.Conclusion：Modified scoring method can estimate head-position dystocia timely and accurately.It is convenient for doctors to made a selection exactly and reduce the incidence of asphyxia neonatorum.
