Analgesic efficacy of single- shot adductor canal block with levobupivacaine and dexmedetomidine in total knee arthroplasty: A randomized clinical trial

Background The goal of this study was to compare the analgesic efficacy dexmedetomidine and levobupivacaine in adductor canal block (ACB) total knee arthroplasty (TKA) patients, as well ambulation ability adverse effects.Methods Sixty ranging age from 18 60 years old with an ASA status I II, had unilateral TKA under spinal anesthesia. They were randomized into two groups; Group L received 20 mL 0.25% LD plus 0.5 µg/kg for ACB. time it took first be requested, amount morphine used a 24-hour period, postoperative pain score, range motion (ROM), 100-foot walking test data, sedation, patient satisfaction, outcomes measured.Results group lower scores VAS either at rest or on movement nearly all-time intervals. mean request (406.77 ± 10.64 min) (515.10 27.98 min, P-value <0.001). dose consumed 24 h significantly (6.47 2.01 mg) when compared (10.93 2.35 mg, P value There significant differences ROM test, 100 foot satisfaction between groups but no major effects both groups.Conclusion addition single-shot ACB is better than alone regarding analgesia, following but, low rate events groups.
