To investigate the clinical effect and value of combined application of low-dose propofol intravenous anesthesia and local anesthesia in manual reduction of shoulder dislocation in emergency practice.

A total of 120 patients with anterior shoulder dislocation admitted to the Emergency Surgery Department of Jinjiang Municipal Hospital from January 2021 to June 2024 were studied. They were divided into local anesthesia group and propofol combined local anesthesia group (combined group) (60 cases each) by random number table method, and the latter group was given a total dose <1.5 mg/kg propofol injection. For measurement data comparison, t test was employed; for count data comparison, chi square test was used to compare reduction time, reduction frequency, subjective satisfaction, pain level, shoulder joint function and complications one month after reduction.

Compared with the local anesthesia group, the combined group demonstrated significantly shorter reduction time (Z=-4.433), lower visual analogue scale (VAS) scores (t=3.684), and higher customer satisfaction questionnaire-8 (CSQ-8) scores (Z=-5.619) after reduction, with statistically significant differences ( all P<0.01). One month after reduction, the Constant-Murley score (excluding muscle strength) were higher in the combined group than in the local anesthesia group (all P<0.01): pain level (t=-3.759), activities of daily life (t=-6.529), and range of motion (t=-4.064).

Low dose propofol intravenous anesthesia combined with local anesthesia can significantly shorten the reduction time, reduce the pain, improve the patient satisfaction and promote the recovery of shoulder joint function in the manual reduction of shoulder dislocation in emergency department, which is worthy of clinical promotion in basic hospitals.
