超声定位法与传统触摸法在婴儿桡动脉穿刺置管中的比较

摘要

Objective To explore the effect on ultrasound localization method with radial artery cannulation in infants.Methods Sixty infants (1 month-1year old)undergoing elective surgical proce-dures required artery pressure,were randomly divided into two groups:ultrasound localization group (group B):the infants were used of portable B ultrasound probe in the wrist with two dimensional ul-trasound image to determine the body position of the radial artery;control group (group C):tradi-tional palpation determine the radial artery puncture position.One puncture success rate,total punc-ture success rate,the period of puncture time and incidence of complications were recorded;MAP, the radial artery diameter,the vertical distance from the ultrasound probe to the skin and the length from the puncture spot to the radial artery were also measured.Results The success rate of first puncture in group B was higher than that of group C (P <0.05),the times of puncture and procedure time were significantly less than those of group C (P <0.05),the incidence of hematoma was lower than that in group C (P <0.05).Conclusion The application of ultrasound-guided method for radial artery cannulation is safe and reliable with accurate localization,highly successful rate of puncture at first time,lower complication and shorter time for placement.%目的：探讨超声定位在婴儿桡动脉穿刺置管中的应用效果。方法选择1月至1岁需要行动脉测压的择期手术患儿60例,随机数字表法分为两组：超声定位组(B 组),使用便携式 B超机在腕部以二维超声图像确定桡动脉位置进行穿刺；触摸组(C 组),以传统触摸法确定桡动脉位置进行穿刺。记录一次穿刺成功率、总成功率、穿刺次数、穿刺时间和并发症发生率；监测穿刺时MAP；测量并记录桡动脉内径及超声探头到皮肤垂直距离,计算穿刺针刺破动脉时进针长度。结果与C 组比较,B 组一次穿刺成功率、总成功率明显升高,穿刺次数明显减少,穿刺时间明显缩短(P <0.05)；B 组血肿发生率明显降低(P <0.05)。结论婴儿桡动脉穿刺置管应用超声定位准确,一次穿刺成功率高,并发症发生率低,穿刺时间短,安全可靠。
