Discomfort in Upper Airways Due to intubation-a Randomized Controlled Trial in a Norwegian Hospital

Not applicable Interventional Ostfold University College · NCT05614609

This study is testing whether using a muscle relaxant or a local anesthetic spray before intubation can help reduce discomfort and hoarseness in patients undergoing anesthesia for certain procedures.

What this trial studies

This clinical trial aims to compare the effectiveness of two different methods for intubation during general anesthesia in gastro- or gynecological procedures. Participants will be randomly assigned to receive either a muscle relaxant (rocuronium) or a local anesthetic spray (lidocaine) on the glottis before intubation. The primary focus is to assess postoperative hoarseness and discomfort in the upper airways one hour after intubation. The study addresses a gap in current research regarding optimal intubation techniques and aims to provide clearer guidelines for anesthetic practices.

Who should consider this trial

Good fit: Ideal candidates are patients classified as ASA I-III who are undergoing gastro- or gynecological procedures under general anesthesia.

Not a fit: Patients with a BMI above 40, anticipated difficult intubation, or those with known allergies to lidocaine or muscle relaxants may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved intubation techniques that minimize discomfort for patients undergoing surgery.

How similar studies have performed: While there is limited research on this specific comparison, previous studies have indicated a need for further investigation into optimal intubation methods, suggesting this approach is novel.
