During i.v. regional anaesthesia, adding paracetamol to the injected lidocaine was shown to improve the overall quality of the block. Onset of motor block was sooner, tourniquet pain was reduced, and recovery of motor and sensory block was delayed, resulting in lower intraoperative pain scores and total systemic analgesic requirements.15 In view of the overall consensus that paracetamol’s actions are centrally mediated, an analgesic benefit conferred from its addition to a peripherally sequestered pool of drug is a surprising finding.
