Analysis of the effect of intravenous visualizer on first superficial vein puncture in obese children

Objective To explore the effect and mechanism of superficial vein puncture for the first time in obese children auxiliary with venous enhancement. Methods From January 2015 to July 2015, 120 children (3-7 years old) with obesity were randomly divided into control group and observation group, 60 cases in each group.The control group used conventional methods to select limbs superficial vein puncture, the observation group guided by visualizer to select limbs superficial vein puncture. Results The superficial vein puncture success rate of observation group was 96.67% for the first time, the puncture time was (78.95±6.68)s; Success rate of control group was 78.33%, the puncture time was (98.44±34.13)s, the differences between two groups were statistically significant(χ2=10.385, t=21.787, all P<0.05). Conclusion Obese children with venous visualizer superficial vein puncture success rate increased significantly, for the first time the puncture time shortened. Key words: Phlebotomy; Obesity; Child
