RESUMEN
Erector spinae plane block (ESPB) has been used as an intervention for providing postoperative analgesia in patients undergoing bariatric and metabolic surgeries. After registering the protocol in PROSPERO, randomized controlled trials and nonrandomized observational studies were searched in various databases till July 2022. The primary outcome was 24-h opioid consumption; the secondary outcomes were intraoperative opioid use, pain scores, time to rescue analgesia, and complications. The risk of bias and Newcastle-Ottawa scale were used to assess the quality of evidence. From the 695 studies identified, 6 studies were selected for analysis. The 24-h opioid consumption was significantly lesser in ESPB group when compared to control (mean difference [MD]: -10.67; 95% confidence interval [CI]: -21.03, -0.31, I² = 99%). The intraoperative opioid consumption was significantly less in the ESPB group (MD: -17.75; 95% CI: -20.36, -15.13, I² = 31%). The time to rescue analgesia was significantly more in the ESPB group (MD: 114.36; CI: 90.42, 138.30, I² = 99%). Although pain scores were significantly less at 6 and 24 h in ESPB group (MD: -2.00, 95% CI: -2.49, -1.51; I² = 0% and MD: -0.48; 95% CI: -0.72, -0.24; I² = 48%), at zero and 12 h, the pain scores were comparable (MD: -1.53, 95% CI: -3.06, -0.00, I² = 97% and MD: -0.80; 95% CI: -1.80, 0.20, I² = 88%). Bilateral ESPB provides opioid-sparing analgesia and better pain scores when compared to control. These results should be interpreted with caution due to high heterogeneity among the included studies.
RESUMEN
Sublingual (SL) buprenorphine is approved for managing acute postoperative pain, characterized by easy administration, good pain relief and good patient compliance. We hypothesized that SL buprenorphine would be a better perioperative analgesic compared to intravenous (IV) opioids like tramadol in patients undergoing mastectomy surgery for breast cancer. After institutional ethics committee approval, we randomized 60 patients with breast cancer into 2 groups. In buprenorphine group, patients received 200 µg of SL buprenorphine thrice daily and in tramadol group patients received 100 mg of IV tramadol thrice daily. The analgesic efficacy of SL buprenorphine was comparable to that of IV tramadol. Visual Analogue Scale scores had no significant difference between the two groups at various time frames (0, 1, 3, 6, 12, 18 and 24 hours) at rest and movement except at 0 and 3 hours during movement when the score was lower in the tramadol group than the buprenorphine group. Four patients in the buprenorphine group received rescue analgesic (IV morphine 3 mg). Analgesic efficacy of SL buprenorphine appears comparable to IV tramadol for managing postoperative pain after mastectomy. SL buprenorphine can be administered sublingually, which is an advantage.

Introduction: Regional anesthesia (RA), i.e., spinal or epidural anesthesia when performed for lower segment cesarean section (LSCS) provides excellent surgical conditions, avoiding manipulation of the maternal airway, maternal satisfaction, and good postoperative analgesia. However, in situations like fetal distress (fetal heart rate abnormalities), obstetric indications (abruption of placenta, antenatal placental bleeding, cord prolapse), maternal refusal for RA, contraindications to neuraxial anesthesia (anticoagulation, coagulopathy), and at times failed RA general anesthesia (GA) is administered. Several studies have demonstrated greater mortality and morbidity when LSCS is done under GA when compared to neuraxial block. Methods: After necessary approval, we retrospectively reviewed data over a period of 1 year (January 1, 2020-December 31, 2020) of LSCS under GA versus RA. The aim was to compare immediate postoperative complications, postoperative pulmonary complications up to 4 weeks from the time of elective and emergency LSCS under either RA or GA. Results: Of the 753 patients who underwent LSCS in one calendar year, there were 272 (36.12%) elective and 481 (63.87%) emergency LSCS. The number of elective LSCS under neuraxial block was 219 (29.09%) and under GA were 53 (7.03%). Emergency LSCS done under neuraxial block were 268 (35.59%) and under GA were 213 (28.28%). There were no adverse pulmonary complications at the end of 4 weeks in either group. Conclusion: RA provides maternal satisfaction and excellent perioperative analgesia in LSCS. Safe GA can be achieved with proper airway planning, if case is attended by at least two anesthesiologist with adequate preoperative fasting, and postoperative monitoring.
RESUMEN
There are several modalities described to manage postoperative pain after a total knee replacement (TKR). Presently the regional anaesthesia techniques used after TKR focus on more peripheral, motor sparing blocks so as to facilitate early ambulation along with good quality pain relief. We describe use of ultrasound guided 3 point genicular nerve block (GNB) for managing postoperative pain successfully after a TKR.
