Brief summary

Recruitment maneuver is frequently used in daily anaesthesia routine to prevent athelectasia and ventilation perfusion mismatch. Especially pneumoperitoneum in laparoscopic surgeries affects the functional residual capacity (FRC) negatively. Recently, FRC can be measured at bedside in intensive care units. The lack of studies evaluating FRC measurements peroperatively and how recruitment maneuvers affect it, attract attention.

Detailed description

An ICU-ventilator capable to measure the FRC will be used for the mechanical ventilation in patients undergıoing laparoscopic surgery, where anaesthesia maintenance will be achieved with TIVA. FRC will be measured in different steps of the operation. In the study group, a recruitment manover will be applied to evaluate its effects on FRC.
