Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pharyngeal packing is a frequently used application to reduce the incidence and severity of postoperative nausea and vomiting (PONV) in patients who undergo nasal surgery. This study aims to research the effects of PP on gastric antral cross-sectional area (ACSA) and hence gastric volume as assessed by ultrasound, therewithal PONV and sore throat were evaluated as secondary outcomes in rhino logic surgeries (Septorhinoplasty, Septoplasty, Functional endoscopic sinus surgery).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Postoperative nausea and vomiting (PONV) after nasal surgery (Septorhinoplasty, Septoplasty, Functional endoscopic sinus surgery) is a very common complication (34-60%). Therefore, pharangeal packing was performed to prevent blood ingestion so as to decrease the incidence of PONV and the risk of aspiration. Also, gastric blood is known to be a powerful emetic. Actually, there is not any evidence in the literature reporting the quantitative values of gastric volumes due to blood ingestion. The aim of this study is to research the effect of pharyngeal packing on the perioperative gastric antral cross-sectional area (ACSA) so the gastric volumes.

Measurements were performed by ultrasound with convex probe in right lateral decubitus position, in order to evaluate the effectiveness of pharyngeal packing in patients undergoing nasal surgery, and to show its effects on PONV and sore throat.
