Background:Ultrasound-guided transversus abdominis plane (TAP) block is done as a part of multimodal analgesia for pain relief after abdominal surgeries. This prospective randomized, double-blind, placebo-controlled trial was conducted to evaluate the postoperative analgesic efficacy of bilateral TAP block in patients undergoing midline colorectal surgeries using ropivacaine.Materials and Methods:Eighty patients scheduled for elective colorectal surgeries involving midline abdominal wall incision under general anesthesia were enrolled in this prospective randomized controlled trial. Group A received TAP block with 20 ml of 0.2% ropivacaine on either side of the abdominal wall, and Group B received 20 ml of normal saline. The time to request for rescue analgesia, total analgesic consumption in 24 h, and satisfaction with the anesthetic technique were assessed.Results:The mean visual analog scale scores at rest and on coughing were higher in control group (P > 0.05). Time (min) to request for the first rescue analgesia was prolonged in study group compared to control group (P < 0.001). The total tramadol consumption in 24 h postoperatively was significantly high in control group (P < 0.001). Nausea/vomiting was more common in control group (P > 0.05). The level of satisfaction concerning postoperative pain control/anesthetic technique was higher in study group (P < 0.001).Conclusion:TAP block produces effective and prolonged postoperative analgesia in patients undergoing midline colorectal surgery. It is a technically simple block to perform with a high margin of safety. It produces a considerable reduction in mean intravenous postoperative tramadol requirements, reduction in postoperative pain scores, and increased time to first request for further analgesia, both at rest and on movement.

Introduction: Magnesium sulphate has the potential to treat and prevent pain by acting as an antagonist at N-methyl-DAspartate (NMDA) receptors. Many researchers found that magnesium sulphate as adjuvant to local anaesthetics reduces analgesic requirements in the postoperative period. Aim: To evaluate magnesium sulphate as an adjuvant to ropivacaine in ultrasound guided bilateral Transversus Abdominis Plane (TAP) block with respect to postlaparoscopic cholecystectomy pain. Materials and Methods: The present randomised doubleblind clinical study was conducted in the Department of Anaesthesiology, SKIMS Medical College, Srinagar, Jammu and Kashmir, between January 2022 and June 2022. Total 80 patients of American Society of Anesthesiologists (ASA) grade I and II were divided into two groups. Group A (n=40) patients received ropivacaine with magnesium and group B (n=40) patients received ropivacaine only. Pain was measured using the Visual Analogue Scale (VAS). Total rescue analgesia consumption during 24 hours, time to first request of rescue analgesia, postoperative nausea vomiting, sedation score and patient satisfaction score were recorded. Mann-Whitney U test was used for VAS score and patient satisfaction score. Results: Mean age of patients was higher in group A (47.95±13.853 years) than group B (46.45±11.940 years). Group A had 12 males and 28 females while in group B, there were 11 males and 29 females in group B. Group A showed better analgesic profile in the form of lower mean VAS, which were statistically significant (p-value<0.05). However, time to first request of rescue analgesia (743.5±58.214 minutes in group A vs 668.50± 214.375 minutes in group B; p-value=0.162) and total dose of rescue analgesia consumption were comparable in both groups (p-value>0.05). Also the sedation score (2.325±0.2529 in group A vs 2.295±0.2562 in group B; p-value=0.600) and patient satisfaction score (PSS) between the two groups (81.05±8.638 in group A vs 80.53±7.517 in group B; p-value=0.665) were statistically not significant. Incidence of postoperative nausea and vomiting was comparable in both groups (p-value=0.924). Conclusion: Addition of magnesium sulphate to ropivacaine in ultrasound guided bilateral TAP block significantly reduced pain scores in patients undergoing laparoscopic cholecystectomy.

Background and Aims: This prospective, randomized, double blind study was undertaken to establish the effect of addition of dexamethasone as an adjunct to epidural ropivacaine in patients of carcinoma rectum undergoing lower anteriorresection. Materials and Methods: Sixty ASA (American Society of Anesthesiologists) class I and II patients undergoing lower anterior resection were enrolled to receive either 6mg or 8mg or 10mg of dexamethasone along with epidural ropivacaine to a total of 10ml test solution in each group for epidural analgesia. Hemodynamic parameters, postoperative analgesia, total requirement of rescue analgesia and adverse events were monitored. Results: Analgesia in the postoperative period was better in Group receiving 10mg of dexamethasone associated with less postoperative rescue analgesic consumption Conclusion: Hence, addition of dexamethasone 10mg to epidural ropivacaine can be advantageous with respect to better postoperative analgesia.
