不同分娩方式产妇对下肢深静脉超声检查数据的影响

Effect of Different Delivery Methods on Ultrasonographic Data of Lower Limb Deep Veins

目的探讨不同分娩方式产妇对下肢深静脉超声检查数据的影响。方法选取2015年7月至2017年2月在我院分娩的158例初产妇,根据不同分娩方式分为自然分娩组(73例)和剖腹分娩组(85例)。比较两组产妇的下肢深静脉超声检查数据。结果剖腹分娩组的左/右侧FV内径、左/右SFV内径、左/右侧POV及左/右侧PTV内径均大于自然分娩组(P<0.05);左/右侧FV血流频谱峰值与左/右侧POV血流频谱峰值均低于自然分娩组(P<0.05)。结论与自然分娩比较,剖腹分娩产妇的双下肢静脉内径增大,静脉血流速度降低,DVT发生风险增大。临床实践中应鼓励产妇尽可能进行自然分娩,并加强剖腹分娩产妇的下肢深静脉超声监测,预防下肢DVT。

Objective To explore the effect of different delivery methods on ultrasonographic data of lower limb deep veins. Methods 158 cases of primiparas with delivery in our hospital from July 2015 to February 2017 were selected and were divided into natural delivery group and cesarean section group according to different delivery methods. The ultrasonographic data of lower limb deep veins were compared between the two groups. Results The internal diameters of left / right FV, left / right SFV, left / right POV and left / right PTV of the cesarean section group were greater than those of the natural delivery group （P 〈0.05）; The peak values of left / right FV blood flow spectrum and left / right POV blood flow spectrum were lower than those of the natural delivery group （P 〈0.05）. Conclusions Compared with natural delivery, the internal diameter of both lower limb veins increases, the venous blood flow velocity decreases, and the risk of DVT increases in caesarean delivery, In clinical practice, pregnant women should be encouraged to carry out natural childbirth as far as possible, and the ultrasonographic monitoring of lower limb deep veins in puerperas with cesarean section should be enhanced to prevent DVT.
