目的:探讨采用超声引导下经皮脐静脉穿刺取胎血的效果。方法:选择2009年12月～2011年12月在高州市人民医院要求中期妊娠引产的患者62例及产前遗传咨询者8例,共70例患者。对此70例患者在B型超声引导下行经皮脐静脉穿刺取胎血。结果:穿刺70例,成功65例,成功率92.8%。70例中,根部穿刺14例,成功14例,游离部穿刺56例,成功48例。穿刺成功率与脐静脉直径呈正相关。70例穿刺者中,26例拔针后出现短暂渗血,均未经处理自行停止。渗血与手术时间长短无关。结论:在超声引导下经皮脐静脉穿刺取胎血具有安全、成功率高、准确性高、敏感性高的优点,为胎儿宫内诊断和治疗开辟了新途径。
Objective: To investigate the effect of ultrasound-guided percutaneous umbilical vein puncture on fetal blood. Methods: From December 2009 to December 2011, 62 patients with prenatal delivery of midterm gestation and 8 prenatal genetic counselors were enrolled in Gaozhou People’s Hospital for a total of 70 patients. In this 70 patients under the guidance of B-type ultrasound percutaneous umbilical vein puncture fetus blood. Results: Puncture in 70 cases, 65 cases were successful, the success rate was 92.8%. In 70 cases, there were 14 cases of root puncture, 14 cases of successful puncture, 56 cases of free puncture and 48 cases of successful puncture. The success rate of puncture and umbilical vein diameter was positively correlated. In 70 cases of puncture, 26 cases of transient bleeding after pulling the needle, were stopped by themselves without treatment. Oozing and surgery has nothing to do with the length of time. Conclusion: Ultrasound-guided percutaneous umbilical vein puncture fetus has the advantages of safety, high success rate, high accuracy and high sensitivity, which opens up a new way for intrauterine diagnosis and treatment.
