An interventional study of recruitment maneuver in Anesthesia, Surgery and Atelectasis, sponsored by Istanbul University. Completed at 2 sites in Turkey. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2020-06-09.
Sponsored by Istanbul University · Not applicable, Interventional, and Screening
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.
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.
301 studies on the registry are indexed under Pulmonary Atelectasis; 80 are open to participants now.
This study's enrollment of 50 is below the median of 61 across 222 interventional studies indexed under Pulmonary Atelectasis.

Exclusion Criteria:
3 FRC measurements will be perforemed, whereby : First measurement; after aneshesia induction and intubation. Second measurement; after pneumoperitoneum Third measurement; end of the operation After the operation,Postoperative Room Air Test (RAT) will be applied.
5 FRC measurements will be performed We will apply recruitment maneuver two times to patients with 30cmH2O pressure for 15 seconds . First Recruitment maneuver will be applied after the fşrst measurement of FRC following intubation Second Recuitment maneuver will be applied at the end of operation First FRC measurement after anesthesia induction and intubation. Second FRC measurement after first recruitment maneuver Third FRC measurement; after pneumoperitoneum Fourth FRC measurement before second recruitment maneuver Fifth FRC measurement after second recruitment maneuver and at the end of operation
Procedure: recruitment maneuver
30 cmH2O pressure 15 seconds
Comparison of FRC measurements at beginning and end of anesthesia
First FRC will be measured after ; the last FRC will be measure bedore the extubation
Time frame: within max 5 minutes after the intubation and with max 5 minutes before the extubation
Positive room air test
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
Time frame: in recovery room 30 minutes after operation
