Intraoperative hemodynamic profile of QLB versus continuous epidural analgesia. The horizontal lines indicate medians; boxes indicate interquartile range; whiskers indicate range. Median (95%CI) values of hemodynamic parameters at time points as follows: MAP: baseline 91 (87.34–95.76) to 90 (88.36–98.99) (p = 0.524); post-induction, 81 (75.76–85.15) to 71 (70.36–79.06) (p = 0.072); gas-insufflation 92 (86.84–97.48) to 88 (82.90–92.52) (p = 0.210); pfannenstiel incision 78 (75.60–84.47) to 75 (73.91–82.03) (p = 0.486); end of surgery 75 (72.48–81.32) to 71 (68.22–75.17) (p = 0.063); 24 h 83.33 (78.72–87.95) to 72.26 (67.69–76.83) (p = 0.001); HR: baseline 80 (77.67–85.30) to 88 (80.16–90.93) (p = 0.215); post-induction 76 (70.87–78.10) to 73 (70.00–80.45) (p = 0.816); gas-insufflation 80 (71.48–81.16) to 74 (72.27–79.80) (p = 0.855); pfannenstiel incision 81 (77.95–90.89) to 80 (76.75–84.73) (p = 0.447); end of surgery 90 (83.64–92.17) to 80 (75.14–88.02) (p = 0.049); 24 h, 82 (64–100) to 82 (72–92) (p = 0.991); CI: baseline 3.20 (3.06–3.74) to 2.90 (2.81–3.38) (p = 0.173); post-induction 2.70 (2.43–3.01) to 2.70 (2.59–3.11) (p = 0.499); gas-insufflation 2.80 (2.44–2.98) to 2.90 (2.73–3.41) (p = 0.095); pfannenstiel incision 2.90 (2.78–3.25) to 2.80 (2.70–3.18) (p = 0.669); end of surgery 3.20 (2.79–3.33) to 3.00 (2.75–3.37) (p = 0.987); 24 h 3.08 (2.67–3.49) to 2.63 (2.34–2.93) (p = 0.071). The p-values were analyzed using Mann-Whitney test, *p < 0.05 is significant. QL, quadratus lumborum; MAP, mean arterial pressure
