Comparative Analysis of the Lung Inflammatory Response After Thoracic Surgery With Single or Double Lung Ventilation: a Randomized, Pilot, Trial

Phase 2
Completed
Conditions
Thoracic Diseases
Surgery
Interventions
Procedure: two lung ventilation
Procedure: one lung ventilation
Registration Number
NCT05982639
Lead Sponsor
Universidade do Extremo Sul Catarinense - Unidade Academica de Ciecias da Saude
Brief Summary

The goal of this clinical trial is to compare in patients undergoing thoracic procedures the lung inflammatory response in on one-lung ventilation and two-lung ventilation strategies The main question to answer is:

• Lung inflammation differs when comparing one to two-lung ventilation strategies during the procedure? Participants will be divided in the classic one lung ventilation or two lung ventilation (using pneumothorax with CO2) and different biomarkers of lung inflammation will be measured after procedures.
