Comparison of conventional technique and pen holding technique for real time ultrasound guided internal jugular venous cannulation – A prospective randomized controlled trail

ultrasound guided central venous cannulation is the standard of care. the incidence of posterior vessel wall puncture in convention ultrasound guided technique is 21% and arterial puncture is 5%. the incidence of posterior vessel wall puncture is reported to be less in penholding method, hence the chance of arterial puncture. the study is designed to compare these two techniques.

Patients will be divided into 2 groups,  group C (conventional ultrasound guided technique group) and group P (penholding method group).  Inside operation room, after induction of anesthesia ultrasound guided internal jugular venous  cannulation will be done using one of these techniques. Incidence of posterior vessel wall puncture, successful cannulation in first attempt, and time taken for successful cannulation will be done by an independent observer not involved in the study. Also complications in both the groups and performers ease will be assessed.
