NCT05384795

Brief Summary

This study aims at comparing a perioperative pulmonary atelectasis score, measured by pulmonary ultrasound, in patients operated undergoing orthopedic surgery under general anesthesia, spinal anesthesia or peripheral nerve block. The association between the atelectasis score and previously identified risk factors will be studied.
