BACKGROUND: Hernia repair is associated with considerable postoperative pain. We studied the analgesic efficacy of bilateral ultrasound-guided erector spinae plane block in patients undergoing open midline epigastric hernia repair (T6–T9). METHODS: Sixty patients 18–65 years of age were randomly allocated into 2 groups. Patients in the erector spinae plane block group received bilateral ultrasound-guided erector spinae plane block at the level of T7 transverse process using 20 mL of bupivacaine 0.25% on each side, while the control group received bilateral sham erector spinae plane block using 1 mL of normal saline. All patients underwent general anesthesia for surgery. Pain severity (visual analog scale), consumption of intraoperative fentanyl, time to first request of rescue analgesia, and postoperative pethidine consumption were recorded over the first 24 hours postoperatively. RESULTS: At 2 hours postoperatively, the visual analog scale pain score was significantly lower in the erector spinae plane block group compared to the control group (estimated main effect of 2.53; P < .001; 95% CI, 1.8–3.2) and remained lower until 12 hours postoperatively (P < .001 from postanesthesia care unit admission to 4 hours postoperatively, .001 at 6 hours, .025 at 8 hours, and .043 at 12 hours). At 18 and 24 hours, visual analog scale pain scores were not significantly different between both groups (P = .634 and .432, respectively). Four patients in the erector spinae plane block group required intraoperative fentanyl compared to 27 patients in control group. The median (quartiles) of intraoperative fentanyl consumption in the erector spinae plane block group was significantly lower (0 µg [0–0 µg]) compared to that of the control group (94 µg [74–130 µg]). Ten patients in the erector spinae plane block group required postoperative rescue pethidine compared to 25 patients in control group. The median [quartiles] of postoperative rescue pethidine consumption was significantly lower in the erector spinae plane block group (0 mg [0–33 mg]) compared to that of the control group (83 mg [64–109 mg]). Time to first rescue analgesic request was significantly prolonged in the erector spinae plane block group compared to control group (P < .001). CONCLUSIONS: Ultrasound-guided bilateral erector spinae plane block provided lower postoperative visual analog scale pain scores and decreased consumption of both intraoperative fentanyl and postoperative rescue analgesia for patients undergoing open epigastric hernia repair.

Background: Many analgesic modalities have been investigated in pediatrics. We studied the analgesic efficacy of bilateral ultrasound-guided erector spinae plane block in pediatric patients undergoing open midline splenectomy.Methods: Sixty patients aged 3-10 years were randomly assigned into two groups:Control group received general anesthesia with bilateral sham erector spinae plane block using 0.3 mL/kg normal saline on each side. Erector spinae plane block group received bilateral ultrasound-guided erector spinae plane block using 0.3 mL/kg bupivacaine 0.25% (on each side) with a maximum dose of 2 mg/kg. Children's Hospital Eastern Ontario Pain Scale (CHEOPS), total consumption of intraoperative fentanyl (1 µg/kg IV in case of inadequate analgesia), time to first rescue analgesic administration, and postoperative paracetamol consumption were recorded over the first 24 hours postoperatively. Results:The median (IQR) postoperative CHEOPS score at 1 hour was lower in erector spinae plane block group (5.0 (4.75 −5.25)) than the control group (7.0 (6.0-10.0)) (P < .001, 95% CI: 1.0; 5.0). The CHEOPS scores for the first eight postoperative hours were lower in the erector spinae plane block group (5.0 (5.0-6.0)) than the control group (6.0 (6.0 −10.0)) (P ˂ .001, 95% CI: 1.0; 2.0). Intraoperative fentanyl administration was higher in the control group 40.0 (21.5-50.0) μg compared to erector spinae plane block group 0.0 (0.0-0.0) μg (P ˂ .001, 95% CI: 23.0; 48.0). The total postoperative paracetamol consumption was higher in the control group (37.5 ± 17.1 mg/kg) compared to erector spinae plane block group (8.5 ± 10.9 mg/kg) (P ˂ .001, 95% CI: 21.57; 36.43). The time to the first postoperative rescue analgesic requirement was longer in the erector spinae plane block group. Conclusion:Ultrasound-guided erector spinae plane block reduced CHEOPS score for the first eight hours postoperatively with the reduction of intraoperative fentanyl and postoperative paracetamol consumptions.

Background Bariatric 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. Methods A 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. Results Visual 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. Conclusion Ultrasound‐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.

Background Surgery of the brain tumors near eloquent areas carries the risk of either disabling neurological deficit or inadequate resection with bad prognosis in both situations. Awake surgery is the gold standard procedure for such lesions. However, it requires certain anesthetic drugs, advanced techniques, and trained teams that are not available in every neurosurgical institute. This work aims to evaluate safety, feasibility, and outcome of operating on patients with space occupying lesions near eloquent areas under scalp block being continuously examined by a neurologist through retrospective study of 20 cases with supratentorial lesions related to language or sensorimotor cortex. Results There were 12 males and 8 females with mean age 36.8 years. Forty percent of patients were presented by motor weakness. Tumors were related to motor cortex in 11 patients and to language areas in 9 patients. Mean operative time was 210 min. Gross or near total resection was achieved in 15cases, four cases had subtotal resection and biopsy only was done in 1 case. Two patients suffered from intraoperative seizures and conversion to general anesthesia was required in one patient. Conclusion Operating on tumors near eloquent brain areas under scalp block and continuous neurological examination during tumor resection proved to be effective in early detection and prevention of permanent major deficits especially in the developing countries with limited resources.
