Brief Summary

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

A prospective, observational, monocentric study aimed at identifying ultrasound changes in anaesthesia on the pulmonary parenchyma after knee arthroplastic surgery using the LUS score in the preoperative, immediate post-operative (D0) and late post-operative (D1) periods.

Detailed Description

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

Post-operative pulmonary complications are responsible from morbidity and mortality close to cardiovascular complications.

Perioperative and post-operative respiratory changes are secondary to anaesthesia (general anaesthesia, elongated position, tidal volume) and to surgery in particular abdominal and cardiothoracic surgery.

Several risk factors related to patients were identified: age, ASA score\> 2, functional dependence, chronic obstructive pulmonary disease, congestive heart failure, obesity, smoking.

Pulmonary ultrasound is a simple and rapid means of monitoring, widely used in resuscitation and developing in anaesthesia.

The hypothesis of the study is that anaesthesia and / or ventilation is responsible for lung lesions observable by ultrasound from the recovery room, even after extra-thoracic surgeries.

To do this, it will perform 3 pleuro-pulmonary ultrasound scans, preoperatively on the day of surgery, post-operatively in the recovery room and the day after surgery. LUS score will be calculated. Preoperative data (morphology, comorbidities), preoperative (ventilation, filling, position, type of anaesthesia - general anaesthesia with intubation or laryngeal mask, spinal anaesthesia- , type of surgery) and postoperative data (constants, oxygen therapy, complications) will be collected.
