What this trial studies

This study investigates a novel airway management technique that combines the use of a laryngeal mask airway (LMA) and an endotracheal tube (ETT) during general anesthesia. The goal is to minimize emergence phenomena such as coughing, straining, and restlessness, which can lead to complications like hypertension and tachycardia. By utilizing the secure airway provided by the ETT while potentially reducing the noxious stimuli associated with emergence from anesthesia, the study aims to improve patient outcomes during recovery. Patients undergoing elective laparoscopic surgery will be monitored for physiological changes and overall emergence experience.

Who should consider this trial

Good fit: Ideal candidates for this study are patients classified as ASA 1-3 who are undergoing elective laparoscopic surgery.

Not a fit: Patients who are high risk for gastric reflux, require translation services, or have anticipated difficult airways may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to smoother recoveries from anesthesia, reducing complications and improving patient comfort.

How similar studies have performed: While the approach of combining LMA and ETT is innovative, similar studies have shown that optimizing airway management can lead to improved outcomes, suggesting potential for success.
