Abstrakt:	Background: Supraclavicular brachial plexus block (SCB) is a common regional analgesic technique for upper limb fracture surgery, but it often leads to rebound pain. Our primary aim is to determine whether different administration methods of esketamine can reduce rebound pain in patients undergoing SCB for upper limb fracture surgery. Methods/design: This study is designed as a single-centre, double-blinded, prospective, randomised controlled trial. Patients undergoing upper limb fracture surgery, who plan to use a tourniquet, aged 18-60 years, with a body mass index of 18-30 kg/m 2 and an American Society of Anaesthesiologists classification of I-III will be randomised into three groups after providing written informed consent: group N (perineural esketamine/ropivacaine); group V (intravenous esketamine/perineural ropivacaine); and group C (perineural ropivacaine). The primary outcome will be the percentage of patients experiencing rebound pain within 24 hours postoperatively. Secondary outcomes include the Numeric Rating Scale (NRS) score of rebound pain, the onset of rebound pain, (since performing SCB), the cumulative area under the curve of NRS pain severity scores through 48 hours postsurgery, postoperative opioid consumption at 48 hours postoperatively, onset and duration of the sensory blockade, onset and duration of the motor blockade and adverse reactions and adverse events. Patients will be followed-up to 48 hours postoperatively. Discussions: This protocol describes the design of a randomised controlled trial to evaluate the effect of different modes of administration of esketamine combined with SCB on the incidence of rebound pain after upper limb fracture surgery. The results may help to identify the most effective methods for managing pain in patients undergoing upper limb fracture surgery. Ethics and Dissemination: This study has been approved by the Ethics Committee of the Deyang People's Hospital (2023-03-010-K01). It was registered on the Chinese Clinical Trials Registry on 24 August 2023. We intend to publish the results in a peer-reviewed journal. Trial Registration Number: ChiCTR2300075083.
