摘要
目的探讨活跃期起始点改变对产程处理的影响。方法回顾性分析2009年1月—12月北京大学第一医院分娩的1 641例初产妇的临床资料。结果阴道分娩组宫口开大3、4、5、6cm为活跃期起始点,平均活跃期时间分别为(4.4±2.1)h、(3.0±1.9)h、(2.1±1.4)h和(1.4±0.9)h,差异均有统计学意义(P<0.01)。不同起始点各组平均第二产程时间和新生儿出生体质量比较,差异无统计学意义(P>0.05)。阴道分娩组宫口开大3、4、5、6cm活跃期停滞发生率分别为25.3%(198/784)、10.7%(26/243)、4.4%(5/113)和0。剖宫产组宫口开大3、4、5、6cm活跃期停滞发生率分别为55.7%(78/140)、46.2%(18/39)、5/15和2/3。宫口开大<6cm发生活跃期停滞者330例,其中229例阴道分娩(69.4%)。单纯以活跃期停滞为剖宫产手术指征者占40%(82/205),其中73.2%(60/82)为宫口开大3cm。结论宫口开大6cm之前活跃期停滞者,仍有阴道分娩机会;活跃期起始点改变可减少宫口开大3cm停滞者行剖宫产的比例。
Objective Our purpose was to examine how the start point of the active phase affect the treatment of labor.Methods Data of 1 641 primipara who dilivered at Peking University First Hospital from January2009 to December 2009 was analyzed retrospectively.Results The average active phase time in the vaginal delivery group was（4.4±2.1）h,（3.0±1.9）h,（2.1±1.4）h and（1.4±0.9）h,respectively in the different diagnostic criteria groups for active phase（cervical dilatation 3cm,4cm 5cm and 6cm）.The difference was significant among the groups（P〈0.01）,while there had no difference in the time of second stage of labor and infant weight in groups.The rates of arrest active phase in different groups were 25.3%（198/784）,10.7%（26/243）,4.4%（5/113）and0,respectively.In cesarean section groups,the rates of arrest active phase in the different diagnostic criteria groups were 55.7%（78/140）,46.2%（18/393）,33.3%（5/15）and 66.7%（2/3）.In the less than 6cm diagnostic criteria groups,there were 330 cases of arrest phases and 69.4%（229/330）of them delivered by vaginal.40%（82/205）of the patients who underwent cesarean section were because of active phase arrest and 73.2%（60/82）of these patients diagnosed by the criteria of cervical dilatation 3cm.Conclusion The 69.4% women of arrest active phase in cervical dilatation〈6cm can vaginal delivery;The change of active phase starting point may reduce the rate of cesarean section being the arrest active phase.The active phase starting point affect on treatment during labor.
