摘要
目的:探讨改良截石位对产妇产后下肢深静脉血栓形成的影响。方法:将380例单胎初产自然分娩产妇随机分为研究组200例和对照组180例,研究组采用改良截石位方式分娩,对照组采用传统截石位方式分娩,分别统计两组产妇产后下肢深静脉血栓形成的发生率及血栓栓塞程度,并进行比较。结果:研究组产妇产后下肢深静脉血栓形成的发生率为10.50%,对照组为20.56%,两组比较差异有统计学意义(P<0.01);研究组产妇产后下肢深静脉血栓轻度栓塞发生率为85.71%、中重度为14.29%,对照组产妇产后下肢深静脉血栓轻度栓塞发生率为48.65%、中重度为51.35%,两组产妇产后下肢深静脉血栓中重度栓塞发生率比较差异有统计学意义(P<0.01)。结论:改良截石位为降低产妇产后下肢深静脉血栓形成发生率及减轻血栓栓塞程度开辟了一条新的预防途径,对减少产后并发症、促进产妇产后康复具有重要意义。
Objective： To discuss the effect of modified lithotomy position on postpartum deep vein thrombosis in the lower extremities.Methods： 380 parturient who had single fetal primiparous vaginal delivery were randomly divided into study group（n=200） and control group（n=180）.Delivery by Modified lithotomy position was adopted in the study group and delivery by traditional lithotomy position was applied in the control group.The incidence of postpartum deep vein thrombosis in the lower extremities and thromboembolism degree were statistically processed in both groups and the results were compared between the two groups.Results： The incidence of postpartum deep vein thrombosis in the lower extremities was 10.50% in the study group and 20.56% in the control group,the difference between the two groups was statistically significant（P〈0.01）;the incidence of mild postpartum deep vein thromboembolism was 85.71%,moderate and severe thromboembolism was 14.29% in the study group and that was respectively 48.65% and 51.35% in the control group.The significant difference was found in the comparison of moderate and severe thromboembolism between the two groups（P〈0.01）.Conclusion： The modified lithotomy position opened up a new way for the reduction of postpartum deep vein thrombosis and the alleviation of thromboembolism degree,which is very important in the prevention of postpartum complications and recovery of parturient.
