Investigating the impact of pharyngeal packing on gastric fluid volume after nasal surgery

The Effects of Pharyngeal Packing on the Postoperative Gastric Fluid Volume Measured by Ultrasound in Patients Undergoing Functional Endoscopic Nasal Surgery, a Randomized Controlled Double-blinded Non-inferiority Trial

Not applicable Interventional Kasr El Aini Hospital · NCT06957275

This study is testing if using pharyngeal packing during nasal surgery affects the amount of fluid in the stomach for patients undergoing the procedure.

What this trial studies

This study aims to evaluate how pharyngeal packing affects gastric fluid volume in patients undergoing functional endoscopic nasal surgery (FESS). Patients will be randomly assigned to either receive pharyngeal packing or not, and their gastric volume will be assessed using ultrasound before the surgery. The study will follow strict fasting guidelines and utilize a standardized ultrasound technique to ensure accurate measurements. The findings could provide insights into optimizing perioperative care for patients undergoing nasal surgery.

Who should consider this trial

Good fit: Ideal candidates are adult patients over 18 years old, classified as ASA physical status I-II, scheduled for elective FESS under general anesthesia.

Not a fit: Patients with conditions that increase the risk of aspiration, such as GERD or a BMI over 35, will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance postoperative care by reducing the risk of aspiration and improving patient outcomes.

How similar studies have performed: While similar studies have explored gastric volume management, this specific approach using pharyngeal packing in the context of FESS is relatively novel.
