Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Atelectasis is one of the most common pulmonary complications in the perioperative period, occurring in 85% to 90% of patients under general anesthesia. It can be responsible for hypoxemia and be associated with postoperative pulmonary complications such as pneumonia. The consequences are a prolongation of the hospital stay and an increase in mortality.

The appearance of perioperative atelectasis is mainly secondary to the induction of general anesthesia with an incidence up to 90%. The different causes are, for example, the administration of muscle relaxants, mechanical ventilation and the position of the patient.

In orthopedic surgery, many procedures are performed under spinal anesthesia or under peripheral nerve block. At present, there are no studies measuring the incidence of atelectasis in patients operated under these two techniques of locoregional anesthesia, with the exception of parturients undergoing cesarean section.

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.
