Introduction: Ultrasound-guided erector spinae plane (ESP) block has emerged as an effective and safe analgesic regional technique and it also provides visceral pain relief. Our aim was to compare the analgesic efficacy of ESP block over transversus abdominis plane (TAP) block under ultrasound guidance following a total abdominal hysterectomy. Methods: This was a prospective, randomized, comparative study. Thirty females posted for elective open total abdominal hysterectomy under general anesthesia were randomly allocated into two groups. Ultrasound-guided ESP block was applied in group E at the T-9 level bilaterally. The study solution was prepared by mixing 20 ml of 0.5% bupivacaine plus 10 ml of 2% lignocaine and 1 ml (50mcg) of fentanyl and 9 ml of normal saline forming total 40 ml of which 20 ml was injected on each side. Group T received ultrasound-guided TAP block with 20 ml of study solution bilaterally. The study solution was prepared similarly by mixing 20 ml of 0.5% bupivacaine plus 10 ml of 2% lignocaine and 1 ml (50mcg) of fentanyl and 9 ml of normal saline (total 40 ml) of which 20 ml was injected into each side. Tramadol 100mg iv was given as rescue analgesia whenever NRS ≥ 4 or on-demand in the postoperative period. The primary outcome was changes in a numerical rating scale (NRS) pain score postoperatively between two groups in 24 h, duration of analgesia and total rescue analgesic required during 24 h. The secondary outcome was patient satisfaction level and side effects if any. Results: Demographic data were comparable in both groups. The NRS pain score was significantly lower ​​​​in group E than in group T at second, third, fourth, fifth (p < 0.001) and at sixth hour (p < 0.05) postoperatively. The mean duration of analgesia was significantly more in Group E (4.73±0.7 h) compared to group T (2.60±0.51 h) (p < 0.001). The tramadol consumption was seen significantly more in 24 h in group T (233.33±25.82 mg) than in group E (193.33±17.59 mg). Patient satisfaction score was significantly higher at 12 h with mean value of 6.07±0.26 in group E compared to 3.40±0.91 in group T. Conclusion: We conclude that ultrasound-guided ESP block provide better postoperative pain control and prolonged duration of analgesia with less tramadol consumption compared to ultrasound-guided TAP block in patients after total abdominal hysterectomy.

Background: Total abdominal hysterectomy (TAH) results in remarkable postoperative pain. Truncal nerve blocks like the quadratus lumborum (QL) block and transversus abdominis plane (TAP) block are described to combat this pain. The aim of the present study was to compare the effectiveness of the QL block with the TAP block in terms of numeric rating scale (NRS) scores as the primary outcome for postoperative pain in TAH. The secondary outcome was time of the first analgesic demand, total analgesic demands required in 24 hr, and patient satisfaction level.Methods: Seventy patients of American Society of Anesthesiologists (ASA) physical status class I and II, aged 35-65 years with a body mass index (BMI) 18-30 kg/m 2 planned for elective TAH under spinal anaesthesia were randomly allocated into two groups. Group Q received QL block and Group T received TAP block under ultrasound guidance with 40 ml of 0.25% bupivacaine of which 20 ml was injected on either side.Results: Demographic data of both groups was comparable. The NRS pain score was significantly lower in Group Q compared to Group T at the fourth and sixth hour. The mean first analgesic demand was significantly early in Group T compared to Group Q (5.69 ± 0.87 hr vs. 11.23 ± 2.22 hr) and total analgesic demands were significantly greater in Group T than Group Q. The mean patient satisfaction score was significantly high in Group Q compared to Group T (5.8 ± 0.41 vs. 4.74 ± 0.44). Conclusion:The combined posterior and anterior approach of the QL block may represent a more efficacious alternative to the TAP block in patients after TAH. Further studies are recommended to evaluate the ideal dose, volume and approach for the QL block.

BackgroundPercutaneous nephrolithotomy (PCNL) is presently the preferred method for managing renal calculi. Visceral pain from the kidney and ureter and somatic pain from the incision site are the primary causes of immediate postoperative pain following PCNL. Poor pain control is associated with unwanted consequences such as patient discomfort, delayed recovery, and prolonged hospital stay. Recently, the erector spinae plane (ESP) block has been used in many thoracic and abdominal surgeries for the control of postoperative pain. In this study, we aimed to assess the effectiveness of the ultrasound-guided ESP block following PCNL. MethodologyThis was a prospective, double-blind, randomized controlled study including 60 patients who were scheduled for elective PCNL under general anesthesia. Patients were randomly divided into two groups. Group E underwent an ultrasound-guided ESP block with 20 mL of the local anesthetic mixture at the T-9 level unilaterally on the side of surgery, and group C was a sham group in which 20 mL of normal saline was injected on the side of surgery. Changes in postoperative pain score were the primary outcome, and the duration of analgesia, the total analgesic requirement in 24 hours, and patient satisfaction were the secondary outcomes. ResultsThe demographic data of both groups were comparable. The Visual Analog Scale score was considerably lower in group E than in group C at two, four, six, and eight hours postoperatively. In group E, the mean analgesic duration was substantially longer than that in group C (8.87 ± 2.45 hours vs. 5.67 ± 1.58 hours, respectively). The tramadol requirement was higher in group C (286.67 ± 62.88 mg) than in group E (133.33 ± 47.95 mg) during the 24-hour postoperative period. At 12 hours, patient satisfaction was considerably higher in group E than in group C (6.73 ± 0.45 vs. 5.87 ± 0.35, respectively). ConclusionsThe ultrasound-guided ESP block provided efficient postoperative pain relief, prolonged duration of analgesia, and reduced tramadol intake after PCNL surgery.

BackgroundTransversus abdominis plane (TAP) block and epidural analgesia are two frequently used regional anaesthesia techniques that attenuate postoperative pain after inguinal hernia repair. AimTo compare the analgesic efficacy between the single-shot epidural block and TAP block for postoperative analgesia in patients undergoing inguinal hernia repair surgery. MethodsForty patients of either gender undergoing elective inguinal hernia surgery of American Society of Anesthesiologists (ASA) class Ⅰ and Ⅱ were randomly allocated into two groups. Group E received a singleshot epidural with 20 ml of 0.25% bupivacaine. Group T received a TAP block with 20 ml of 0.25% bupivacaine under ultrasound guidance. Postoperative pain was evaluated by the visual analog scale (VAS). Rescue analgesia was given on VAS score ≥ 4 or on-demand in the postoperative period. The primary outcome included VAS score at 15 min, 1st h, 2nd h, 6th h, 12th h, and 24th h after the block. The secondary outcome was the analgesia duration, the total rescue analgesia dose required, and the patient satisfaction level. ResultsThe VAS pain scores were significantly lower in the epidural group compared to the TAP group at the 2nd, 6th, 12th, and 24th h postoperatively (p<0.0001). The mean duration of analgesia was significantly more in Group E (576.75±96.64 min) compared to Group T (276.75±105.56 min). The total analgesic consumption was seen significantly more in 24 h in Group T than in Group E. Patient satisfaction score was significantly higher with a mean value of 5.55±0.6 in group E compared to 4.75±0.72 in group T. ConclusionA single-shot epidural provides better postoperative pain control than a TAP block. The duration of the first analgesic demand was prolonged, with less analgesic consumption in the epidural group.
