Comparison of Conventional and Manometry Measurement Methods in the Evaluation of Perioperative Laryngeal Edema by USG in Patients Undergoing Lumbar Stabilization Surgery

NA · Fatih Sultan Mehmet Training and Research Hospital · NCT06770322

This study is testing two different ways to measure swelling in the throat of patients having back surgery to see if one method helps doctors better manage complications after surgery.

What this trial studies

This study evaluates the effects of two different methods for measuring laryngeal edema in patients undergoing lumbar stabilization surgery while positioned prone. The investigators will use conventional techniques and manometry measurement methods alongside ultrasonography to assess perioperative complications related to laryngeal edema. The aim is to improve patient outcomes by identifying and addressing potential complications during the postoperative period.

Who should consider this trial

Good fit: Ideal candidates are patients aged 18-65 who are scheduled for elective lumbar spinal surgery under general anesthesia and are classified as ASA I-III.

Not a fit: Patients over 65 years of age, those with significant comorbidities, or those with a history of specific upper airway surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better management of laryngeal edema, reducing complications and improving recovery for patients undergoing lumbar spinal surgery.

How similar studies have performed: While there is limited data on this specific approach, similar studies have shown promise in managing laryngeal edema during surgical procedures.
