NCT06770322

Brief Summary

In this study, the investigators aimed to evaluate perioperative laryngeal edema in patients undergoing lumbar stabilization surgery in the pron position, which the investigators use in our routine anesthesia practice, by using conventional and manometry measurement methods and ultrasonography, which the investigators also use frequently in our routine, and to evaluate complications related to laryngeal edema in postoperative service follow-up.

Outcome Measures

Primary Outcomes (1)

  • Measurement of airway column width

    Measurement of the effect of conventional and manometry methods on air column width by ultrasonography. With ultrasonography, laryngeal edema development can be observed in patients by measuring the air column width after intubation and before extubation in the transverse axis with a linear probe over the patient's cricothyroid membrane

    through study completion, an average of 6 months

Secondary Outcomes (1)

  • Detection of complications due to postoperative laryngeal edema

    It will be evaluated at PACU 5th minute and postoperative 4, 8, 24th hours

Study Arms (2)

Conventional

OTHER

According to the clinician's own practice, the cuff of the endotracheal intubation tube will be manually inflated with the help of a syringe and the pressure will be measured with manometry and a note will be taken.

Procedure: Conventional

Manometer

EXPERIMENTAL

The cuff pressure will be measured by manometry and the cuff of the endotracheal intubation tube will be inflated with 25-30 cmH2O.

Procedure: manometer
