Objective:
To explore the effects of pharyngeal packing on antral cross-sectional area, gastric volume and post-operative complications.
Methods:
In this prospective, randomised, controlled study, 180 patients were randomly assigned to a control group or a pharyngeal packing group. Gastric antral dimensions were measured with pre- and post-operative ultrasound scanning. Presence and severity of post-operative nausea and vomiting and sore throat were recorded.
Results:
Post-operative antral cross-sectional area and gastric volume were significantly larger in the pharyngeal packing group compared to the control group. The incidence and severity of post-operative nausea and vomiting were significantly less in the pharyngeal packing group. More frequent and severe sore throat was observed in the control group within the ward. An increased Apfel simplified risk score and post-operative antral cross-sectional area were associated with post-operative nausea and vomiting during the first 2 hours, whereas septorhinoplasty and functional endoscopic sinus surgery, absent pharyngeal packing, and lower American Society of Anesthesiologists' physical status were associated with post-operative nausea and vomiting within the ward.
Conclusion:
Regardless of operation type, pharyngeal packing use resulted in smaller gastric volume, which was associated with reduced post-operative nausea and vomiting frequency and severity, and lower sore throat incidence.
