Clinical Trial Summary

Background: There is a lack of studies regarding Optimal (best) positive end-expiratory pressure (PEEP) in prone position during surgery, and its relation with optimal PEEP in supine position. Hypothesis: In patients undergoing scheduled spinal surgery, optimal PEEP in the prone position is lower than optimal PEEP in the supine position. Aims: To assess the difference optimal PEEP in supine vs. prone positions in patients undergoing spine surgery. To evaluate the changes in optimal PEEP in prone position throughout the surgical procedure. Methods: Observational study, one center. Main variable: optimal PEEP. Secondary variables: PaO2, pCO2 and dynamic compliance (Crd) in prone and supine position.


Description:

Recruitment: Patients scheduled for spine surgery were Main outcome: Optimal PEEP determined after a pulmonary recruitment manoeuvre in supine and in prone position and every hour during the surgery in prone position. Secondary outcomes: Pulmonary compliance, blood gas analysis and hemodynamic parameters
