Background and aimTransversus abdominis plane block (TAP block) is a novel procedure to provide postoperative analgesia following inguinal hernia surgery. The utilization of ultrasound has greatly augmented the success rate of this block and additionally avoiding complications. The aim of our study was to gauge the analgesic efficacy of ultrasound-guided TAP block in patients undergoing unilateral inguinal hernia repair.Materials and methodsSixty patients scheduled for elective inguinal hernia repair were selected for the study. At the end of the surgical procedure, they were randomly divided into two groups. Ultrasound-guided TAP block was performed with 20 mL of ropivacaine 0.2% (group A) or normal saline (group B). Visual analog scale (VAS) scores were used to assess pain. Paracetamol was given if VAS > 3 and tramadol was used when VAS > 6. Patients were monitored for VAS scores and total analgesic consumption for the 24-hour period.ResultsThe TAP block with ropivacaine (group A) reduced VAS scores at 4, 6, and 12 hours. There was no distinction in VAS scores at 0, 2, and 24 hours between the two groups. The duration of analgesia for TAP block with ropivacaine lasted for 390 minutes. Total analgesics consumption was also significantly reduced in group A than group B. No complication was reported to TAP block in both the groups.ConclusionThe ultrasound-guided TAP block provides good postoperative analgesia, reduces analgesic requirements, and provides good VAS scores with fewer complications following inguinal hernia surgery.

Background and Aims:The supraclavicular and infraclavicular brachial plexus blocks have a similar distribution of anaesthesia, and both can be used effectively for surgeries of the upper limb. This study aimed to compare the supraclavicular and infraclavicular approaches of brachial plexus blocks, guided by ultrasound and neurostimulation.Methods:Sixty adult patients scheduled for elective upper limb surgery of the elbow and/or below were randomly divided into two groups: infraclavicular Group (I) and supraclavicular Group (S). All the blocks were performed with the aid of ultrasound-guided nerve stimulator confirmation. The two groups were compared with respect to block performance time, onset of sensory and motor blockade, readiness for surgery, success rate and complications. The statistical analysis was performed with Student t-test and Chi-square test.Results:The block performance time for the infraclavicular group was 9.57 ± 3.19 min, whereas for supraclavicular group, it was 11.53 ± 2.90 min with similar success rates (93.3%). Onset of sensory blockade was achieved earlier (6.43 ± 2.61 min) in Group I than Group S (8.45 ± 2.87 min, P = 0.006). The onset of motor blockade was similar in Group I (7.32 ± 2.90 min) and Group S (8.68 ± 3.50 min, P = 0.121). The patient satisfaction was similar in both the groups. One patient had a pneumothorax, three patients developed Horner syndrome and another had clinically symptomatic diaphragmatic paresis in Group S.Conclusion: The infraclavicular block is more rapidly executed compared to supraclavicular block with similar success rates and fewer complications in the presence of ultrasound and nerve stimulator and hence should be preferred.
