Background:Various analgesic modalities have been used for postoperative analgesia in patients undergoing inguinal hernia surgery. In this randomized clinical trial, we have compared the analgesic efficacy of transversus abdominis plane (TAP) block with that of ilioinguinal/iliohypogastric (IIIH) nerve block with wound infiltration in patients undergoing unilateral open inguinal hernia repair.Aim:The primary objective of this study was to compare the efficacy of postoperative analgesia of ultrasound-guided TAP block and IIIH block with wound infiltration (WI) in patients undergoing open inguinal hernia surgery.Settings and Design:This was a randomized clinical trial performed in a tertiary care hospital.Materials and Methods:Sixty patients scheduled for hernia repair were randomized into two groups, Group T and Group I. Postoperatively, under ultrasound guidance, Group T received 20 ml of 0.25% ropivacaine – TAP block and Group I received 10 ml of 0.25% ropivacaine – IIIH block + WI with 10 ml of 0.25% ropivacaine. The primary outcome measure was the time to rescue analgesia in the first 24 h postoperatively. Fentanyl along with diclofenac was given as first rescue analgesic when the patient complained of pain.Statistical Analysis:Statistical comparisons were performed using Student's t-test and Chi-square test.Results:Mean time to rescue analgesia was 5.900 ± 1.881 h and 3.766 ± 1.754 h (P < 0.001) and the mean pain scores were 5.73 ± 0.784 and 6.03 ± 0.850 for Group TAP and IIIH + WI, respectively. Hemodynamics were stable in both the groups. One-third of the patients received one dose of paracetamol in addition to the rescue analgesic in the first 24 h. There were no complications attributed to the block.Conclusion:As a multimodal analgesic regimen, definitely both TAP block and IIIH block with wound infiltration have a supporting role in providing analgesia in the postoperative period for adult inguinal hernia repair. In this study, ultrasound-guided TAP block provided longer pain control postoperatively than IIIH block with WI after inguinal hernia repair. There were no complications attributed to the blocks in either of the group.
Background:The supraclavicular approach is considered to be the easiest and most effective approach to block the brachial plexus for upper limb surgeries. The classical approach using the anatomical landmark technique was associated with higher failure rates and complications. Ultrasonography (USG) guidance and peripheral nerve stimulator (PNS) have improved the success rates and safety margin.Aims:The aim of the present study is to compare USG with PNS in supraclavicular brachial plexus block for upper limb surgeries with respect to the onset of motor and sensory blockade, total duration of blockade, procedure time, and complications.Settings and Design:Prospective, randomized controlled study.Subject and Methods:Sixty patients aged above 18 years scheduled for elective upper limb surgery were randomly allocated into two groups. Group A patients received supraclavicular brachial plexus block under ultrasound guidance and in Group B patients, PNS was used. In both groups, local anesthetic mixture consisting of 15 ml of 0.5% bupivacaine and 10 ml of 2% lignocaine with 1:200,000 adrenaline were used.Statistical Analysis:Independent t-test used to compare mean between groups; Chi-square test for categorical variables.Results:The procedure time was shorter with USG (11.57 ± 2.75 min) compared to PNS (21.73 ± 4.84). The onset time of sensory block (12.83 ± 3.64 min vs. 16 ± 3.57 min) and onset of motor block (23 ± 4.27 min vs. 27 ± 3.85 min) were significantly shorter in Group A compared to Group B (P < 0.05). The duration of sensory block was significantly prolonged in Group A (8.00 ± 0.891 h) compared to Group B (7.25 ± 1.418 h). None of the patients in either groups developed any complications.Conclusion:The ultrasound-guided supraclavicular brachial plexus block can be done quicker, with a faster onset of sensory and motor block compared to nerve stimulator technique.
To evaluate the role of bispectral index monitoring as an adjunct to balanced anesthesia in patients with myasthenia gravis undergoing transsternal thymectomy without the use of neuromuscular blocking agents, 10 patients were enrolled into this prospective observational study. After oral midazolam premedication, general anesthesia was induced with fentanyl, propofol, and sevoflurane. Tracheal intubation was performed without neuromuscular blocking agents. During maintenance, continuous monitoring of physiological and bispectral index parameters was used to titrate the doses of remifentanil, propofol, and sevoflurane. Sevoflurane concentration and propofol doses were adjusted to achieve bispectral index values in the high 30s to low 40s. Propofol was discontinued when the sternum was approximated. Remifentanil infusion was stopped on subcutaneous tissue closure, and sevoflurane was switched off when nearing completion of skin closure. Tracheal extubation was performed when extubation criteria were met. On extubation, bispectral index levels were above 90. The median time from extubation to discontinuation of propofol was 28 +/- 4 min, that of remifentanil was 21 +/- 4 min, and it was 9 +/- 5 min for sevoflurane. Bispectral index monitoring provided excellent hemodynamic control during surgery, and allowed early problem-free tracheal extubation.
