Comparison of conventional needle holding technique and pen holding method of needle holding for real-time ultrasound-guided internal jugular venous cannulation - A randomised parallel-group study.

Background And Aims: Ultrasound-guided central venous (CV) cannulation is the standard of care for inserting CV catheter in the right internal jugular vein (RIJV). However, mechanical complications can still occur. The primary objective of this study was to compare the incidence of posterior vessel wall puncture (PVWP) using conventional needle holding technique with pen holding method of needle holding technique for IJV cannulation.

Comparison of erector spinae plane block and local anaesthetic infiltration of the incision site for postoperative analgesia in percutaneous nephrolithotomy - A randomised parallel-group study.

Background And Aims: Erector spinae plane block (ESPB) has been found effective in providing postoperative analgesia following a myriad of surgeries. This study was designed to evaluate the effectiveness of ultrasonography (USG) guided erector spinae plane block to provide postoperative analgesia following percutaneous nephrolithotomy (PCNL).

Methods: This was a prospective, double-blinded, randomised parallel-group study conducted in patients undergoing PCNL.
