Abstract：Objective To investigate the effect of drawing-line puncture on blood collection from radial artery in infants. Methods From March 2016 to March 2020, 256 children with radial artery blood collection needs admitted to Department of Pediatric Respiratory Medicine of Affiliated Hospital of Binzhou Medical College were selected retrospctively as observation objects. According to different blood collection methods, they were divided into observation group and control group, each group had 128 cases. In the control group, the traditional puncture method was used to collect blood, and the observation group used the drawing-line puncture method to collect blood. The success rate, puncture effect, total incidence of adverse events and family satisfaction of the two groups were compared. Results The success rate of one-time puncture in the observation group was higher than that in the control group, the difference was statistically significant (P＜0.05); the puncture time in the observation group was shorter than that in the control group,the swelling diameter was smaller than that in the control group, the differences were statistically significant (P＜0.05);the incidence of adverse events in the observation group was lower than that in the control group, the difference was statistically significant (P＜0.05), and the satisfaction degree of family members in the observation group was higher than that in the control group, the difference was statistically significant (P＜0.05). Conclusion The application of drawingline puncture on blood collection from the radial artery in infants can not only increase the probability of one-time puncture success, but also reduce the puncture time and trauma of the infants. There are fewer adverse reactions to the puncture and higher family satisfaction, which is helpful for improving tension between nurses and patients, the overall intervention effect is significant, and it is worthy of promotion.
