Kiwi胎头吸引器在阴道助产分娩中的应用效果及安全性分析

Application effect and safety analysis of Kiwi fetal head aspirator in vaginal midwifery

目的探讨Kiwi胎头吸引器在阴道助产分娩中的应用效果及安全性。方法选取166例行阴道助产分娩产妇,采用随机数字表法将其分为试验组和对照组,各83例。试验组采用Kiwi胎头吸引器阴道助产分娩,对照组使用传统胎头吸引器进行阴道助产分娩。比较两组的阴道助产分娩成功率及母婴并发症发生情况。结果试验组产妇阴道助产成功分娩率为100%,对照组产妇阴道助产成功分娩率为95.18%,试验组产妇阴道助产成功分娩率高于对照组,差异具有统计学意义(P<0.05)。试验组和对照组产妇产后并发症发生率比较,差异无统计学意义(P>0.05),但试验组产后出血率1.20%明显低于对照组的9.64%,差异具有统计学意义(P<0.05)。对照组行传统胎头吸引助产失败的4例产妇均改行产钳术成功助产阴道分娩。两组新生儿1min、5min、10min的Apgar评分、酸碱度(pH)、氧分压(PO_(2))、二氧化碳分压(PCO_(2))及血碱剩余(BE)指标比较,差异无统计学意义(P>0.05)。试验组、对照组新生儿头皮下血肿发生率分别为12.05%、24.10%,比较差异具有统计学意义(P<0.05)。结论与传统胎头吸引器相比,使用Kiwi胎头吸引器助产可提高阴道助产成功率,降低产妇产后出血风险及新生儿头皮下血肿的发生率。

Objective To investigate the application effect and safety of Kiwi fetal head aspirator in vaginal midwifery.Methods 166 parturients with vaginal midwifery were selected and divided into experimental group and control group with 83 cases in each group by random number table method.The experimental group used Kiwi fetal head aspirator for vaginal delivery,and the control group used traditional fetal head aspirator for vaginal delivery.The success rate of vaginal midwifery and the incidence of maternal and infant complications were compared between the two groups.Results The rate of successful delivery by vaginal assisted delivery was 100%in the experimental group and 95.18%in the control group,and the rate of successful delivery by vaginal assisted delivery in the experimental group was higher than that in the control group,with statistical significance(P<0.05).There was no statistical significance in the incidence of postpartum complications between the experimental group and the control group(P>0.05),but the postpartum hemorrhage rate of the experimental group(1.20%)was significantly lower than that of the control group(9.64%),with statistical significance(P<0.05).In the control group,all the 4 cases of women who failed in traditional fetal head attraction were successfully assisted by forceps delivery.There were no significant differences in Apgar score,pH,partial pressure of oxygen(PO_(2)),partial pressure of carbon dioxide(PCO_(2))and blood base excess(BE)between the two groups at 1 min,5 min and 10 min(P>0.05).The incidence of subscalp hematoma in experimental group and control group was 12.05%and 24.10%,respectively,and the difference was statistically significant(P<0.05).Conclusion Compared with traditional fetal head aspirator,Kiwi fetal head aspirator can improve the success rate of vaginal midwifery,reduce the risk of postpartum hemorrhage and the incidence of neonatal subscalp hematoma.
