Trendelenburg Angle and Upper Airway Ultrasound Findings in Laparoscopic Hysterectomy

NCT07794917 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 68

Summary

This observational study was designed to evaluate whether the Trendelenburg position used during laparoscopic hysterectomy is associated with swelling of the upper airway.

Women scheduled for elective laparoscopic hysterectomy under general anesthesia were included. During surgery, the angle of the operating table in the Trendelenburg position was measured. The upper airway was assessed with bedside ultrasound by measuring the distance from the skin to the epiglottis and the thickness of the tongue at different time points before and during surgery.

The study did not assign participants to any treatment or intervention. All participants received standard surgical and anesthetic care. After surgery, participants were monitored for early airway-related findings such as noisy breathing after extubation, need for extra oxygen, low oxygen saturation, or need for reintubation.

Conditions

  • Upper Airway Edema
  • Postextubation Stridor

Trendelenburg positioning during laparoscopic hysterectomy

Participants underwent elective laparoscopic hysterectomy under general anesthesia as part of standard clinical care. Trendelenburg positioning was applied according to routine surgical need and was not assigned by the study protocol. The Trendelenburg angle was measured and recorded during surgery. Upper airway ultrasound measurements were obtained before and during surgery, and participants were monitored for postoperative clinical airway findings during the first 24 hours.
