Influence of anaesthesia induction and associated disparities on radial artery cannulation success

Abstract

Purpose: This study aimed to compare the procedure durations, the number of attempts and first attempt success rates in radial artery(RA) cannulations performed before and after anaesthesia induction. Secondarily, anaesthesia-related determinants of success were to be identified. Materials and Methods: This study included 73 adult patients. All cannulations were with traditional palpation technique. Ultrasonography was used for arterial diameter/depth measurements. Cannulation time(s), number of attempts and first attempt success/failure were recorded. Results: A total of 91 cannulations was performed. Median cannulation times were 30s (min-max:17-378) and 37s (min-max:10-217); first attempt success rates were %87.5 and %87.8 in preinduction and postinduction groups, respectively.. Local anaesthetic infiltration increased RA depth but did not affect RA height and width. Body mass index(BMI) and presence of atherosclerotic heart disease(ASHD) and/or peripheral vascular disease(PVD) were found as independent predictors of cannulation time. Conclusion: RA cannulation success was unaffected by anaesthesia induction.
