Summary

This study aims to investigate the effects of the personalized application of respiratory pressures applied to patients undergoing laparoscopic bariatric surgery when they are connected to a ventilator under general anesthesia, on the postoperative period. The effects of the ventilation practices that are fixed in routine practice and revised according to various variables during the surgery during artificial respiration after intubation under general anesthesia will be examined with ultrasonography. No change will be made to the routine anesthesia practice for this purpose, the pressure values in the ventilator under general anesthesia will be adjusted during the surgery within the framework of the values used in anesthesia practice. After the surgery, the lung area will be examined with ultrasound in the recovery unit and the findings will be recorded. This study does not have any undesirable effects or risks. This study does not include any interventional procedures.

Conditions

  • Obesity
  • Postoperative Bariatric Surgery
  • Laparoscopic Surgery
  • Individualized PEEP Treatment Strategy

Interventions

PROCEDURE

dynamic compliance guided PEEP titration

In order to find the individualized optimal PEEP value, PEEP will be increased at 2-minute intervals with a maximum peak pressure of 45 cmH2O and a driving pressure of 15 cmH2O. Recruitment will be performed. When the target is reached, the PEEP value will be adjusted to the value at which the highest dynamic compliance is achieved by decreasing it.
