Trial Outcomes & Findings for Technique for Successful Ultrasound-guided Peripheral Vascular Access (NCT NCT01975974)

Results Overview

we will compare the first attempt success rate using proposed ultrasound technique in total of 100 obese (BMI\>30) surgical patients with existing published data. Mata-analysis of first attempt success rate using ultrasound for intravenous cannulation is 61.8% We predict 90% (50% improvement) success rate using the proposed ultrasound technique. Based on this prediction, a sample size of 100 patients provided more than 90% power to compare there two groups at the 0.05 significance level with a two-sided Chi square test.
