Summary

Postoperative pulmonary complications (PPC) are a common problem in patients undergoing surgery using one-lung invasive ventilation. Major pulmonary complications such as atelectasis, bronchospasm, and pneumonia can lead to respiratory failure. PPC are the main cause of mortality in the postoperative period in patients after thoracic surgery. The study aimed to compare the effectiveness of using a mechanical insufflator-exsufflator after video-assisted thoracoscopic surgery using one-lung ventilation to reduce postoperative pulmonary complications as compared to standard therapy.

Detailed description

Postoperative pulmonary complications (PPC) are a common problem in patients undergoing surgery using one-lung invasive ventilation. Major pulmonary complications such as atelectasis, bronchospasm, and pneumonia can lead to respiratory failure. PPC are the main cause of mortality in the postoperative period in patients after thoracic surgery. The incidence of PPC ranges from 5% to 80%. Patients undergoing thoracic surgery are usually at high risk. Most often these are elderly people with concomitant diseases. Most of these patients are smokers, have occupational exposures, and are therefore at even greater risk of developing pulmonary complications. Part of their problem is due to poor baseline pulmonary function. Improving mucus production in the postoperative period using a mechanical insufflator-exsufflator may help reduce the incidence of complications.

Interventions

Type	Name	Description
DEVICE	Mechanical insufflator-exsufflator	In the active comparator group a mechanical insufflator-exsufflator will be used in the postoperative period 6 and 24 hours after extubation as follows ("coughing maneuver"): application of inspiratory pressure of 40-70 cm of water (the minimum value to achieve a peak cough flow of 300 l/min) for 2 seconds with the subsequent creation of an expiratory vacuum of -40 cm of water within 2 seconds. During inhalation and exhalation, the patient will apply oscillations with a frequency of 10 Hz and an amplitude of 10 cm of water. A series of 10 such maneuvers will be used, with a pause of a few seconds to ensure patient comfort. The "coughing" maneuver will be performed through an oronasal mask tightly pressed to the face.
