    BackgroundBariatric surgery is frequently complicated with considerable postoperative pain. We evaluated the impact of ultrasound-guided erector spinae plane block on perioperative analgesia and pulmonary functions following laparoscopic bariatric surgery.MethodsA total of 60 patients aged 18 to 65 years with a body mass index (BMI) of ≥ 40 kg/m2 were randomly allocated into two groups. Patients received either bilateral erector spinae plane block using 20 mL bupivacaine 0.25% at the level of the T7 transverse process or bilateral sham block using 20 mL normal saline on each side. Visual analog scale, intraoperative fentanyl consumption, the cumulative 24-hour postoperative morphine consumption, and postoperative pulmonary functions were recorded.ResultsVisual analog scale for the first eight postoperative hours were significantly lower in the erector spinae plane block group than the control group. The median (interquartile range [IQR]) intraoperative fentanyl consumption was higher in the control group (159.5 [112.0 to 177.8] μg) than in the erector spinae plane block group (0.0 [0.0 to 74.5] μg) (P < 0.001). The median (IQR) cumulative 24-hour postoperative morphine consumption was lower in the erector spinae plane block group (8.0 [7.0 to 9.0] mg) than in the control group (21.0 [17.0 to 26.25] mg) (P < 0.001, 95% CI [11.00, 15.00]). Postoperative pulmonary functions were significantly impaired in both groups compared with baseline values without significant difference between both groups.ConclusionUltrasound-guided erector spinae plane block provided satisfactory postoperative analgesia following laparoscopic bariatric surgery with decreased analgesic consumption without significant difference in postoperative pulmonary functions compared with the control group.© 2020 World Institute of Pain.
