Abstract

 This study aimed to clarify characteristics of observations and procedures followed by expert nurses for the selection of intravenous insertion site, focusing on the veins identified. We performed the study on 11 competent (control group) and 13 expert nurses. The nurses were recorded while selecting the site for intravenous infusion on the forearm of a mock patient. We performed an interview after the recording, including questions that aimed to clarify the purpose of procedures and characteristics of observations. During the interview, we watched the video of the procedure and examined each process followed during the procedure.<br>　Subsequently, we identified 12 procedures of palpation, including 9 for competent nurses and 11 for expert nurses. Analysis of the average time, number of observation points, variations of procedures etc., showed no significant difference between the 2 groups. The average time for site selection by expert nurses was 147.4±83.2 seconds, control group was 111.8±37.2 seconds. Regarding site selection, control group tended to select from multiple areas, including the dorsal venous network of left hand and basilic vein of right forearm. On the other hand, expert nurses tended to select from limited areas, and 61.5% of them selected the cephalic vein as the insertion site.
