Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
For each patient who will undergo nasal surgery,
In the preoperative unit, preoperative ultrasonographic examination of gastric antrum will be performed,
After intubation for general anesthesia, same anesthesiologist will place soft pharyngeal packs in oropharynx.
Pharygeal packing is an procedure of placing woven cotton gauzes in oropharnx.
After the completion of postoperative ultrasonographic evaluation, the pharyngeal packs will be removed.
In two separate sessions (before anaesthesia induction and before postoperative extubation), an experienced radiologist and ananaesthesiologist will evaluate the stomach from the antrum by abdominal ultrasonography.
All the procedures will execute in operating theatre.

Outcomes
Primary outcome [1] 319315 0
Measure of gastric volume with abdominal ultrasonography
Three images were acquired in each session, and the mean antero-posterior (AP) and cranio-caudal (CC) diameters of the gastric antrum (in millimetres) were calculated.
Then, the antral cross-sectional area (ACSA) was calculated using the formula CSA = (AP × CC × 3.14) / 4. The total volume of the stomach was then estimated using a previously tested and validated mathematical model with the following formula: GV (in millilitres) = 27 + 14.6 × CSA (in square millimetres) – 1.28 × age.

Primary outcome [2] 319545 0
Postoperative nausea and vomiting (PONV)
Kortilla’s scale will use for PONV;
Absence of any emetic episode and nausea: MILD PONV:
Mild nausea or one emetic episode or short-lasting (10 min) nausea of any severity triggered by an exogenous stimulus (e.g. drinking, eating or postoperative movement followed by diminished nausea and the patient’s feeling well throughout the entire observation period with no antiemetic drug requirement: MODERATE PONV
One or two emetic episodes or moderate or severe nausea without exogenous stimulus, or single requirement for antiemetic therapy more than two emetic or moderate to severe nauseous episodes requiring at least one antiemetic administration: SEVERE PONV

Summary
Brief summary
Pharyngeal packing (PP) is commonly performed to reduce the incidence of perioperative blood ingestion (PBI) in nasal surgery (NS), and thus the incidence and severity of postoperative nausea and vomiting (PONV). This study examined the effects of PP on the perioperative gastric volume (GV) and PONV in patients undergoing NS by ultrasound assessment.
