The purpose of this study is to compare patient satisfaction with patient-controlled sedation with propofol and anesthesiologist-controlled sedation during orthopedic procedures of the upper limb under locoregional anesthesia.

This is an interventional, prospective, randomized, open-label, controlled, single-center study designed to evaluate the less commonly used patient-controlled sedation, comparing it with sedation administered by the anesthesiologist in a population of patients indicated for orthopedic upper limb surgery requiring additional sedation.

Once informed consent has been signed, patients will be randomized into one of two study arms in a 1:1 ratio, stratified by age:

• Experimental arm (1) : patient-controlled propofol sedation ;
• Control arm (2) : anesthesiologist-controlled propofol sedation.

Patient participation in the study lasts from 1 to 7 days maximum (from preoperative inclusion to hospital discharge).
