    BackgroundPatient dissatisfaction has been previously associated with motor block in shoulder surgery patients receiving brachial plexus block. For elective minor wrist and hand surgery, we tested whether a regional block accelerating the early return of upper extremity motor function would improve patient satisfaction compared with a long-acting proximal brachial plexus block.MethodsA total of 177 patients having elective 'minor' wrist and hand surgery under awake regional block randomly received adrenalized infraclavicular lidocaine 2% 10 ml+ropivacaine 0.75% 20 ml ('long acting', n=90), or adrenalized infraclavicular lidocaine 1.5% 30 ml+long-acting distal median, radial, and ulnar nerve blocks selected according to the anticipated area of postoperative pain ('short acting', n=87). A blinded observer questioned patients on day 1 for numerically rated (0-10) subjective outcomes.ResultsWith 95% power, there was no evidence for a 1-point satisfaction shift in the short acting group: satisfaction was similarly high for both groups [median (inter-quartile range)=10 (8-10) vs 10 (8-10), P=0.71], and also demonstrated strong evidence for equivalence [mean difference (95% confidence interval)=-0.18 (-0.70 to 0.35)]. There was no difference between the groups for weakness- or numbness-related dissatisfaction (low for both groups), or for numerically rated or time to first pain. Surgical anaesthesia success was similar between the groups (short acting, 97% vs 93%, P=0.50), although more patients in the short acting group had surgery initiated in ≤25 min (P=0.03).ConclusionsPatient satisfaction is not improved after elective minor wrist and hand surgery with a regional block accelerating the early return of motor function. For this surgery, motor block related to a long-acting brachial plexus block does not appear to cause patient dissatisfaction. Clinical Trial Registration number.
