Intravenous regional anaesthesia of the bovine foot

Objective: To compare the analgesic effects of combination of 0.5% Lidocaine plus Ketorolac in intravenous regionalanaesthesia technique with those of Lidocaine (0.5%) alone to prevent post operative pain after intravenous regional anaesthesia (Biersblock). Study design: Randomized Control Trial. Place and duration of study: The study was carried out at Department of Anaesthesiology,Intensive Care and pain management, Combined Military hospital, Rawalpindi from July 2008 to February 2009. Patients and Methods: Thestudy was conducted after complete evaluation of risk / benefit ratio to the patients. On the basis of random number method the patients weredivided into two equal groups (group A and group B). The number of patients in each group was 75. Group A was assigned Lidocaine in a dose of200mg 40ml of 0.5% solution and group B was assigned injection Ketorolac 30mg added to Lidocaine in a dose of 200mg 40ml of 0.5% solution.The patients were kept in post anaesthesia care unit for two hours and pain intensity was measured by visual analogue scale(VAS) on 15,30minutes,1hour, 1.5 and at 2 hours after the cuff deflation. The analgesic efficacy recorded on the basis of visual analog scale of two groups, wascompared using student’s t - test. p value of less than 0.05 was considered statistically significant. Results: In group A 33 males and 42 femaleswere enrolled for the study while in group B there were 38 males and 37 females. The mean age of the patients in group A was 34.31 ± 6.03years while in group B was 32.99 ± 6.08 years. Patients were also classified according to ASA classification in which 87 patients were classifiedas ASA – I and 63 patients as ASA – II. Group B which received Ketorolac in addition to Lidocaine for Bier’s block had low visual analogue scoresas compared to group A which received only Lidocaine for Bier’s block. P values obtained after the comparison of the mean VAS of two groupsat 15 minutes, 30 minutes, 1 hour, 1.5 hours and 2 hours were all less than 0.05 (0.002 for 15 minutes, 0.004 for 30 minutes, 0.001 for 1 hour,0.004 for 1.5 hours and 0.001 for 2 hours). Conclusions: Ketorolac improves the postoperative analgesia markedly when used with Lidocainein intravenous regional anaesthesia.

Intravenous Regional Anaesthesia

Background and objectives Distal upper extremity surgery is commonly performed under regional anaesthesia, including intravenous regional anaesthesia (IVRA) and ultrasound-guided forearm nerve block. This study aimed to investigate if ultrasound-guided forearm nerve block is superior to forearm IVRA in producing a surgical block in patients undergoing carpal tunnel release. Methods In this observer-blinded, randomized controlled superiority trial, 100 patients undergoing carpal tunnel release were randomized to receive ultrasound-guided forearm nerve block (n = 50) or forearm IVRA (n = 50). The primary outcome was anaesthetic efficacy evaluated by classifying the blocks as complete vs incomplete. Complete anaesthesia was defined as total sensory block, incomplete anaesthesia as mild pain requiring more analgesics or need of general anaesthesia. Pain intensity on a numeric rating scale (0–10) was recorded. Surgeon satisfaction with hemostasis, surgical time, and OR stay time were recorded. Patient satisfaction with the quality of the block was assessed at POD 1. Results In total, 43 (86%) of the forearm nerve blocks were evaluated as complete, compared to 33 (66%) of the forearm IVRA (p = 0.019). After the forearm nerve block, pain intensity was lower at discharge (-1.76 points lower, 95% CI (-2.92, -0.59), p = 0.0006) compared to patients treated with forearm IVRA. No differences in pain experienced at the start of the surgery, during surgery, and at POD1, nor in surgical time or total OR stay were observed between groups. Surgeon (p = 0.0016) and patient satisfaction (p = 0.0023) were slightly higher after forearm nerve block. Conclusion An ultrasound-guided forearm nerve block is superior compared to forearm IVRA in providing a surgical block in patients undergoing carpal tunnel release. Trial registration This trial was registered as NCT03411551.
