两种桡动脉穿刺法在新生儿采血中的应用效果

目的探讨触摸法和连线定位法两种穿刺方法在新生儿桡动脉穿刺采血中的应用效果。方法将进行桡动脉穿刺采集血液标本的600例患儿随机分为实验组与对照组各300例。实验组在穿刺方法上运用解剖连线定位方法，对照组采用传统的触摸动脉穿刺定位方法。比较两组的一次性穿刺成功率、穿刺所用时间及穿刺后并发症发生的情况。结果两组患儿一次性穿刺成功率，实验组为96．0％高于对照组的88．3％，两组比较差异有统计学意义（x^2=12．21，P〈0．01）；实验组穿刺所用时间（2．82±0．24）min，低于对照组（3．93±0．50）min，两组比较差异有统计学意义（t=9．897，P〈0．01）；实验组穿刺后并发症发生率为3．3％低于对照组的7．6％，两组比较差异有统计学意义（x^2=5．44，P〈0．05）。结论应用连线解剖定位穿刺方法进行桡动脉采血，可操作性强、成功率高，值得临床推广应用。

Effect of two radial artery puncture methods on the neonatal blood collection

Objective To explore touch puncture method and wired positioning puncture method on the neonatal blood collection via radial artery. Methods Totals of 600 newborns needed blood collection via radial artery were randomly into experimental group and control group, per group 300 cases. Control group received traditional touch method to puncture, while experimental group on the bases of puncture method received anatomy wired positioning puncture. Then, the success ratio of one-time puncture, puncture time and complications were compared. Results The success ratio of one-time puncture of experimental group was 96.0% higher than control group that was 88.3%, and the difference was Statistically significant（ x^2 = 12.21, P 〈0. 01 ）;Puncture time of experimental group was （2.82 ± 0.24 ）min lower than control group that was （3.93 ± 0.50） min, and the difference was statistically significant （ t = 9. 897, P 〈 0. 01 ） ; The incidence of complications of experimental group was 3.3% lower than control group that was 7.6%, and the difference was statistically significant （x^2 = 5.44, P 〈 0. 05 ）. Conclusions Anatomy wired positioning method using in neonatal blood collection has a strong operability and high puncture success ratio, which deserves to be spread and used in the clinic.
