ABSTRACT
BACKGROUND:
Superior trunk block (STB) provides noninferior analgesia to the interscalene block and reduces the risk of hemidiaphragmatic paralysis (HDP). Recently, supraclavicular spreading has also been shown to occur during costoclavicular block (CCB), presenting as an alternative analgesic technique for shoulder surgery.OBJECTIVE:
The aim of this study was to determine whether there is a difference in postoperative pain scores and HDP incidence between STB and CCB.DESIGN:
Prospective randomised controlled trial.SETTING:
Chungnam National University Hospital in Daejeon from January to July 2021. PATIENTS Seventy patients, aged 20 to 70âyears with ASA Physical Status classifications I to III and scheduled for elective arthroscopic rotator cuff repair were recruited. INTERVENTION Ultrasound-guided STB or CCB was performed with 20âml 0.5% ropivacaine. MAIN OUTCOMEMEASURES:
The primary outcome was the pain score (numeric rating scale, NRS) at 1âh postsurgery. A 1.4 (NRS) noninferiority margin was set a priori . The incidence of HDP, postoperative change of pulmonary function and postoperative opioid use were included as secondary outcomes.RESULTS:
The pain score was higher in the CCB group compared with the STB group at 1âh postoperatively (median difference, 2; 95% confidence interval (CI), 1 to 3; noninferiority was not demonstrated). Two patients in the CCB group received a rescue interscalene block due to severe postoperative pain. The incidence of complete HDP was lower in the CCB group (risk difference, -26%; 95% CI, -6 to -45%; P â<â0.001). The median reduction in forced vital capacity and forced expiratory volume in 1âs were also significantly lower in the CCB group.CONCLUSION:
Although the incidence of HDP was lower, CCB did not show noninferiority in immediate postoperative analgesia compared with STB in arthroscopic shoulder surgery.
