Efficacy of Recruitment Maneuver in Pediatric Patients Under General Anesthesia

Healthy Clinical Trial

Official title:
The Assessment of Efficacy and Safety of Step-wise up and Down PEEP Titration in Healthy Pediatric Patients Under General Anesthesia

Clinical Trial Summary

During general anesthesia lung collapses and atelectasis occurs. Preservation of atelectasis can cause pulmonary disfunction. The goal of safe anesthesia is to protect the lungs intraoperatively. Positive end-expiratory pressure (PEEP) is distending pressure that prevents alveolar collapse during mechanical ventilation and is a part of recruitment maneuver that is often used in patients on mechanical ventilation. Overall effect of PEEP is improvement in lung function. PEEP can have adverse effects on hemodynamics. The objective of this study was to assess the effect of step up and down PEEP titration on lung function and hemodynamics in healthy preschool children during general anesthesia. One group of children was ventilated with constant PEEP. the other was submitted to PEEP titration. Changes in lung compliance, gas exchange and hemodynamic status were documented as well as any unwanted effects.

Clinical Trial Description

Seventy preschool children American Society of Anesthesiologists classification system (ASA) I and II scheduled for non-cardiothoracic surgery were allocated in two groups. Interventional group (n=35) received PEEP titration and Control group (n=35) didn't. They were ventilated only with PEEP 3. PEEP titration: In Intervention group, 20 minutes before the end of anesthesia PEEP was increased by 2 on every 5 breaths to 11. Ventilation with PEEP 11 was maintained for 2 minutes. Then PEEP was reduced by 2 on every 5 breaths to 5 and remain as until awakening. Total time to perform titration was 5 minutes. Blood was collected in both groups, in equal points of time that is: after induction, 20 minutes before the end of surgery and after the end of surgery (20th minute). Investigators tested differences of outcome variables between groups and within the Interventional group before and after PEEP titration. Hemodynamic monitoring and monitoring of lung function were conducted in Interventional group to observe changes during PEEP titration. ;
