Introduction Selective posterior rhizotomy (SPR) is a preferred procedure for relieving spastic children with cerebral palsy, but it is associated with severe pain and significant emergence agitation (EA). The thoracolumbar interfascial plane (TLIP) block provides an effective blockade to the dorsal branch of the spinal nerve. We hypothesise that the TLIP block may be an effective tool to alleviate EA and postoperative pain scores in children with cerebral palsy undergoing SPR. Methods and analysis This study is a single-centre, randomised, parallel-controlled trial being conducted in Beijing, China. A total of 50 paediatric patients with cerebral palsy scheduled for SPR are randomised in a 1:1 ratio to receive bilateral TLIP block with 0.2% ropivacaine 0.5 mL/kg or control. Patients in the TLIP group receive general anaesthesia combined with TLIP block, while patients in the control group receive only general anaesthesia, without a TLIP block. The primary outcome is the Paediatric Anaesthesia Emergence Delirium Score. The secondary outcomes are the incidence of EA, the Wong-Baker Faces Pain-rating Scale, the perioperative haemodynamics, the intraoperative remifentanil and propofol dosage, the extubation time and recovery time, and adverse reactions. Ethics and dissemination This study was approved by the Ethics Committee of Dongzhimen Hospital, Beijing University of Chinese Medicine on 21 September 2023 (2023DZMEC-379–02). Written informed consent is obtained from the legal guardian of each patient. The results of this study will be published in peer-reviewed international journals. Trial registration number ChiCTR2300076397

Background : Although interscalene nerve block is considered as the standard analgesic method for arthroscopic shoulder surgery, it is not indicated for patients with respiratory comorbidity. Periarticular infiltration is usually used for postoperative analgesia following orthopedic surgery, with uncertain analgesic effects. Infraspinatus-teres minor interfascial (ITM) block is an innovative method used in arthroscopic shoulder surgery. We supposed that ITM block combined with periarticular infiltration could provide adequate analgesia for patients undergoing arthroscopic shoulder surgery. Methods : This is a randomized, parallel-controlled, prospective, single-center study. 56 patients scheduled for arthroscopic shoulder surgery will be randomized into two groups: ITM block combined with periarticular infiltration group (ITM group) and periarticular infiltration group (PAI group). Periarticular infiltration will be administered to all patients following surgery. The primary outcome is the time from the end of surgery to the first press of the patient-controlled analgesia pump (PCA) in the two groups. Secondary outcomes are the following: intraoperative remifentanil and propofol consumption, hemodynamic changes, VAS scores, frequency of PCA compression, remedy analgesic consumption, length of hospital stay, and adverse reactions. Discussion : This study will demonstrate the analgesic efficacy of ITM block combined with periarticular infiltrationin arthroscopic shoulder surgery.

We supposed that ITM block combined with periarticular infiltration could provide adequate analgesia for patients undergoing arthroscopic shoulder surgery. This is a randomized, parallel-controlled, prospective, single-center study. Fifty-six patients scheduled for arthroscopic shoulder surgery will be randomized into two groups: ITM block combined with periarticular infiltration group (ITM group) and periarticular infiltration group (PAI group). Periarticular infiltration will be administered to all patients following surgery. The primary outcome is the time from the end of surgery to the first press of the patient-controlled analgesia pump (PCA) in the two groups. Secondary outcomes are the following: intraoperative remifentanil and propofol consumption, hemodynamic changes, VAS scores, frequency of PCA compression, remedy analgesic consumption, length of hospital stay, patients satisfaction score, and adverse reactions.
