新型婴幼儿桡动脉穿刺技术在临床中的应用

Clinical application of new radial artery puncture technique in infants

目的观察超声引导下双线隔离定位技术在婴幼儿桡动脉穿刺中的临床应用效果。方法选择2017年3月~2018年12月在首都医科大学附属北京友谊医院拟行桡动脉穿刺的患儿40例,采取随机数字表法分为对照组与观察组,每组各20例。对照组采用常规的超声引导下桡动脉穿刺技术,而观察组采用超声双线隔离定位技术下进行桡动脉穿刺。主要观察目标是比较第一次尝试成功率,次要观察目标是穿刺失败率、超声定位时间和并发症发生情况。结果观察组的首次插管成功率为85%,明显高而于对照组的55%,差异有统计学意义(P<0.05);观察组超声定位时间明显短于对照组,差异有统计学意义(P<0.05)。观察组穿刺失败率及出血发生率低于对照组,差异有统计学意义(P<0.05)。结论超声引导下双隔离线定位技术不仅有利于缩短超声定位,而且也有利于提高超声引导下婴幼儿桡动脉的首次穿刺成功率。

Objective To observe the clinical effect of ultrasound-guided double-line isolation and localization technique in infant radial artery puncture. Methods A total of 40 infants who were treated with radial artery puncture were chosen from March 2017 to December 2018 in Beijing Friendship Hospital, Capital Medical University. The patients were divided into control group and observation group through random number table, with 20 cases in each group. The control group was treated with conventional ultrasound-guided radial artery puncture technique, while the observation group received ultrasound double-line isolation positioning technique for radial artery puncture. The primary observation goal was to compare the success rate of the first attempt, and the secondary observation goal was the failure rate of puncture, the time of ultrasound localization, and the incidence of complications. Results The success rate of first intubation in the observation group was 85%, which was significantly higher than that in the control group (55%), the difference was statistically significant (P < 0.05). The ultrasound localization time in the observation group was significantly shorter than that in the control group, the difference was statistically significant (P < 0.05). The incidences of venipuncture failure and bleeding in the observation group were lower than that in the control group, the differences were statistically significant (P < 0.05). Conclusion Ultrasound-guided double-line isolation and localization technique is not only helpful in shortening the ultrasound localization, but also in improving the success rate of the first puncture of radial artery in infants under ultrasound guidance.
