目的探讨超声定位在脐静脉不同的穿刺部位的一次穿刺命中率。缩短脐静脉穿刺时间,减少感染机会,降低手术并发症。方法回顾性分析对110例因各种原因行产前诊断的孕妇(孕22-28周)进行B超引导下脐静脉穿刺术。分四组不同部位穿刺。结果A组定位在脐轮处14例,一次命中5例,一次命中率36%。B组定位在游离段50例,一次命中26例,一次命中率52%。C组定位在脐带根部31例,一次命中22例,一次命中率71%。D组定位在脐带绕颈(腹)处15例,一次命中15例,一次命中率100%。结论超声定位在D组处的一次命中率高于前三组。
Objective To investigate the puncture rate of ultrasound in different puncture sites of umbilical vein. Shorten the time of umbilical vein puncture, reduce the chance of infection and reduce surgical complications. Methods Retrospective analysis of 110 cases of prenatal diagnosis of pregnant women for various reasons (22-28 weeks pregnant) under the B-guided umbilical vein puncture. Divided into four groups of different parts puncture. Results A group located in the umbilical wheel at 14 cases, a hit in 5 cases, a hit rate of 36%. Group B was located in the free segment in 50 cases, a hit in 26 cases, a hit rate of 52%. C group located in the root of the umbilical cord in 31 cases, a hit in 22 cases, a hit rate of 71%. D group located in the umbilical cord around the neck (abdominal) at 15 cases, a hit in 15 cases, a hit rate of 100%. Conclusion Ultrasound localization in the D group at a hit rate was higher than the first three groups.
