Effects of Recruitment Maneuver on Functional Residual Capacity

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.

About this study

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.

Treatment and study plan

recruitment maneuver

Procedure

30 cmH2O pressure 15 seconds

Primary outcomes

  1. Comparison of FRC measurements at beginning and end of anesthesia

    Time frame: within max 5 minutes after the intubation and with max 5 minutes before the extubation

    First FRC will be measured after ; the last FRC will be measure bedore the extubation

Secondary outcomes

  1. Positive room air test

    Time frame: in recovery room 30 minutes after operation

    in recovery room when patient modified aldrete score ≥ 9 patient SPO2 when breathing in room air If patients' spo2 value ≤ 96%, named as room air test positive
