Conditions

Lung Ultrasound, Positive End Expiratory Pressure

Brief summary

The main purpose of the study is to compare the effectiveness of PEEP application in terms of perioperative oxygenation level in the use of classical LMA and i-gel, which is often preferred. The secondary aim is to compare parameters such as gastric insufflation and the rate of postoperative pulmonary complication development in the case of PEEP with two supraglottic airway devices.

Interventions

DIAGNOSTIC_TESTPEEP

PEEP of 7 cmH2O will be applied 5 minutes after classical LMA or i-gel insertion.

DIAGNOSTIC_TESTZEEP

PEEP of 0 cmH2O will be applied 5 minutes after classical LMA or i-gel insertion.

MeasureTime frameDescription
LUS score preopBaselineLoss of ventilation will be evaluated by calculating the LUS score. Each region will be scored according to the LUS model as follows: Presence of lung deviation with lines or less than two isolated B-lines is scored as 0; 1 point in the presence of more than one well-defined B line; presence of more than one combined B line, 2 points; and when a tissue pattern characterized by dynamic air bronchograms (lung consolidation) is presented, the score is 3. The worst ultrasound pattern observed in each region will be recorded and used to calculate the sum of the scores.
