Brief 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.

Study Arms (2)

Intervention group

EXPERIMENTAL

Intervention: increase and decrease positive end-expiratory pressure. PEEP titration: 20 minutes before the end of anesthesia and surgery PEEP was increased by 2 on every 5 breaths to 11 ventilation was maintained on PEEP 11 for 2 minutes.Then, PEEP was reduced by 2 for every 5 breaths to 5.Total time to titrate was 5 minutes.

Procedure: increase and decrease positive end-expiratory pressure

Control

NO INTERVENTION

Ventilation with PEEP 3 during anesthesia and surgery

Interventions

20 minutes before the end of anesthesia and surgery 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 cmH2O

Also known as: ventilation with PEEP 3
