Transmuscular Quadratus Lumborum Block for Laparoscopic Cholecystectomy

Ultrasoundguided Transmuscular Quadratus Lumborum Block After Elective Laparoscopic Cholecystectomy. A Prospective, Randomized Clinical Trial.

The TQL block may prove a valuable method for treating postoperative pain following scopic removal of the gall bladder.

The trial will compare active TQL block versus placebo TQL block after said operation.

The hypothesis is that active TQL block significantly will reduce postoperative pain following scopic removal of the gall bladder compared with placebo TQL block.
