What this trial studies

This study compares the effects of two types of endotracheal tubes, the Henan Tuoren and Smiths Portex, on complications during nasal intubation in patients undergoing oro-maxillofacial surgery. Patients will be monitored for vital signs and assessed for bleeding and other complications during the intubation process. The study aims to determine which tube results in less bleeding and fewer complications, thereby improving patient outcomes during anesthesia. Participants will be randomly assigned to one of the two tube groups and evaluated for various parameters post-intubation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20-65 undergoing oro-maxillofacial surgery without systemic diseases.

Not a fit: Patients with difficult airways, previous head and neck surgery, or nasal cavity obstructions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved intubation techniques that minimize complications and enhance patient safety during surgery.

How similar studies have performed: Other studies have explored various intubation techniques, but this specific comparison of these two endotracheal tubes is novel.
