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( x2 =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 (x2 =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.
