Clinical Trial Summary

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).

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The crosssectional area (ACSA) (Postoperative) (mm2) (Postoperative)	measurements are done with USG and calculated with this formula CSA = (AP (anterior-posterior) diameter × CC (cranio-caudal) diameter× 3.14) / 4.	10 minutes before extubation
Secondary	Postoperative presence and severity of PONV	The severity of PONV was assessed according to the four points score: None (0 point), nausea (1 point), nausea with maximum of two vomiting episodes (2 points), more than two vomiting episodes (3 points).; When PONV with = 2 points metaclopropamid 10 mg was done, and in order to repetition granisetron 3 mg was added.	at the first, second and 24th hours in PACU and at the ward
Secondary	The severity of sore throat	No pain (0 point), mild pain (1 point), moderate pain (2 points) and severe pain (3 points). Patients with severe sore throat were given paracetamol.	at the first, second and 24th hours in PACU and at the ward
Secondary	Blood volume in the suction system	weighing sponge, pad, compress and blood volume in the aspirator	in the perioperative period
