Analgesic effects of transversus abdminis plane block with additional of magnesium sulfate to local anesthetic: a prospective randomized controlled study in patients after laparoscopic cholecystectomy - Analgesic effects of transversus abdminis plane block with additional of magnesium sulfate to local anesthetic: a prospective randomized controlled study in patients after laparoscopic cholecystectomy

The primary endpoint, the numerical rating scale (NRS) at 24 hours after surgery, did not differ significantly. There was a significant difference in postoperative NRS only in the immediate postoperative period. The median (interquartile range) NRS immediately after surgery was 4.5 (1.0-5.0) in the R group and 0.0 (0.0-2.3) in the M group, P value 0.007. There were no significant differences in other parameters.
