What this trial studies

This study aims to evaluate the effectiveness of oropharyngeal packs soaked in either ketamine or magnesium sulfate in reducing the incidence and severity of postoperative sore throat (POST) following elective nasal surgeries performed under general anesthesia. The research will involve 90 adult patients classified as ASA physical status I and II, who will undergo various nasal procedures. The primary outcome will focus on the reduction of POST, while secondary outcomes will assess postoperative nausea and vomiting. The study will compare the effects of these two interventions against a saline control to determine the most effective approach for alleviating these common postoperative complications.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 60 with ASA physical status I or II scheduled for elective nasal surgery requiring general anesthesia.

Not a fit: Patients with a history of recent respiratory infections, known allergies to the study drugs, or those requiring difficult intubation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of postoperative sore throat and nausea, improving recovery experiences for patients undergoing nasal surgery.

How similar studies have performed: While the use of oropharyngeal packs in nasal surgeries is common, the specific comparison of ketamine and magnesium sulfate for this purpose is relatively novel and has not been extensively tested in prior studies.
