The plasma concentrations of IL-6 at baseline and day one between the two groups. Data were compared by repeated-measures analysis of varianceTwo patients in the QLB group were excluded due to failed QLB block, one of which was overweight and quadratus lumborum (QL) muscle, erector spinae, and psoas major couldn’t be identified well, and the other was due to a large rash at the puncture site. The patients in the QLB group had a shorter time to first off-bed activities from the end of surgery than in the control group (
