Efficacy Evaluation of a non-human experimental model for ultrasound-guided superficial venous puncture: clinical randomized assay

Abstract

Introduction: The use of a venipuncture simulator facilitates technique learning and improves skills, which reduces the risk of venipuncture complications in humans. Objective: To evaluate the efficacy of a non-human experimental model for Ultrasound guided superficial venipuncture. Methods: We randomized 39 nurses in two groups: A and B. The training had three steps: 1 - theoretical class, 2 - practical class, with the ultrasound device and 3 - ultrasound-guided puncture training in the non-human model. The group A participated in steps 1, 2 and 3 and group B in steps 1 and 2. After training, both groups were released for ultrasound guided venipuncture. Results: The success in puncture in group A (n = 20) was 90% and in group B (n = 19) it was 68.42%. In the sum of the identification and the puncture times, the average of group A was 61.5 seconds (95% CI, 33.58; 106.95) and in group B was 148.0 seconds (95% CI, 114.54; 208.44), which was statistically significant (p = 0.007, without overlapping the interval estimates). Conclusion: Nurses who received training with the nonhuman model had better identification and puncture times.
