Kiwi Omni胎头吸引器在阴道助产分娩中的应用

Application of Kiwi OmniCup system in assisted vaginal delivery

目的评估Kiwi Omni胎头吸引器在阴道助产分娩中的安全性及有效性。方法收集规律产检且通过阴道助产分娩的45例孕妇作为研究对象,其中使用Kiwi Omni胎头吸引器的16例为观察组,使用产钳的29例为对照组。对比观察组与对照组的产妇阴道裂伤率、会阴侧切率、新生儿出生后阿普加评分、新生儿脐动脉血气分析及新生儿头皮下血肿、颅内出血等情况,评估不同阴道助产分娩方式的安全性。结果观察组产妇中阴道裂伤1例(6%)、会阴侧切6例(32%),对照组产妇中出现阴道裂伤10例(34%)、会阴侧切23例(88%),观察组产妇的阴道裂伤率及会阴侧切率均低于对照组(P均<0.05)。观察组新生儿中出现头皮下血肿4例(25%),对照组新生儿中仅1例(3%)出现头皮下血肿,2组比较差异有统计学意义(P<0.05)。2组新生儿的阿普加评分、脐动脉血气分析、转科率及住院时间比较差异均无统计学意义(P均>0.05)。结论 Kiwi Omni胎头吸引器在阴道助产分娩中可以降低产妇软产道损伤,不增加新生儿窒息率及新生儿转科率。

Objective To evaluate the safety and efficacy of the Kiwi OmniCup system in assisted vaginal delivery. Methods Forty five pregnant women who received prenatal examination and underwent vaginal delivery were recruited in this study. Sixteen subjects utilizing the Kiwi OmniCup system were assigned into the observation group and 29 using obstetrics forceps were allocated into the control group. Vaginal laceration rate, lateral episiotomy rate, the Apgar score after birth, neonate umbilical cord artery blood gas analysis, neonate subscalp hematoma and neonate intracranial hemotoma were statistically compared between the observation and control groups. The safety of different modes of vaginal delivery was evaluated. Results In the observation group, 1 case （6% ） had vaginal laceration, and 6 （32% ） received lateral episiotomy, significantly less compared with 10 （34% ） of vaginal laceration and 23 （88% ） of lateral episiotomy in the control group （ both P 〈 0. 05 ） . In the observation group, 4 neonates （25%） presented with sub scalp hematoma, significantly higher than 3% （ n = 1） in the control group （P 〈0. 05 ）. The Apgar score, umbilical cord artery blood gas analysis, referral rate and length of hospital stay did not significantly differ between the observation and control groups （all P 〉0. 05） . Conclusions The Kiwi OmniCup system can be applied in the assisted vaginal delivery, which can reduce the incidence of vaginal injury without increase of neonate asphyxia rate or the referral rate.
