Comparison of ultrasound-guided paravertebral block versus erector spinae plane block for postoperative analgesia after percutaneous nephrolithotomy - A randomised, double-blind, controlled study.

4.39 (1.2) min, respectively).[ 18 ] A meta-analysis of USG-guided PVB versus ESPB for various surgeries showed that block performance time to complete ESPB was shorter than for PVB (mean duration =4.05, 95% CI: 2.95 to 5.14), which was highly significant.[ 7 ] The drawback of the present study could be that anaesthesiologists in our research had performed a minimum of 10 USG PVB and ESP blocks each, which may be adequate to learn ESPB but may not be enough for PVB, as previous studies have shown that PVB has a longer learning curve.
