Dynamic needle tip positioning versus short axis technique for ultrasound-guided internal jugular venous cannulation in adult surgical patients: a randomized controlled trial

This study is a randomized, double blind, parallel group, single-centre trial comparing the first attempt success rate between dynamic needle tip positioning (DNTP) versus short axis (SA) of ultrasound -guide IJV cannulation in adult surgical patients, that will be conducted in one center (AIIMS, New Delhi) in India. The primary outcome measures will be first attempt success rate. The secondary outcomes will be overall success rate, no. of attempts, no. of redirection, cannulation time, procedural time, incidence of complications (carotid artery puncture, PWVP, hematoma, pneumothorax and haemothorax) during ultrasound -guide IJV cannulation.
