Postoperative nausea and vomiting (PONV) is one of the most common and unpleasant complications of cosmetic surgery — affecting 20–30% of unprotected patients. Korean anesthesia practice uses risk stratification and multi-modal prophylaxis to reduce this dramatically. This guide explains the 2026 protocols and what patients should expect.
What PONV is and why it matters
- Nausea and/or vomiting in 24–48 hours after general anesthesia.
- Significant patient distress.
- Wound disruption from retching.
- Bleeding risk from elevated venous pressure.
- Aspiration risk during recovery.
- Delayed discharge from clinic.
- Patient satisfaction strongly affected.
Risk factors (Apfel score)
Modern Korean anesthesia uses Apfel score to stratify risk:
- Female sex (1 point).
- Non-smoking status (1 point).
- Previous PONV or motion sickness (1 point).
- Anticipated postoperative opioid use (1 point).
- Total: 0–4 points.
Risk by score
- 0 points: 10% PONV risk.
- 1 point: 21% risk.
- 2 points: 39% risk.
- 3 points: 61% risk.
- 4 points: 79% risk.
Korean-specific risk factors
- Female (most cosmetic patients).
- Non-smoking (Korean cosmetic patients often non-smokers).
- Often history of motion sickness.
- Surgery duration >1 hour common.
- Patient-controlled analgesia (PCA) opioid use.
- Result: most cosmetic patients in moderate-to-high PONV risk category.
Procedure-specific PONV risk
Higher PONV risk procedures
- Laparotomy (abdominal surgery).
- Long-duration general anesthesia.
- Procedures requiring high-dose opioids.
- Body contouring, abdominoplasty.
Lower PONV risk procedures
- Brief outpatient procedures.
- Local anesthesia procedures.
- Minor injectable treatments.
- Small body procedures.
Cosmetic surgery PONV reality
- Most cosmetic surgery: moderate PONV risk.
- Facial procedures: moderate risk.
- Eyelid surgery: lower risk (often local anesthesia).
- Rhinoplasty: moderate risk.
- Major body procedures: higher risk.
Korean prevention protocol
Risk stratification
- Apfel score calculated pre-op.
- Adjustment based on procedure-specific factors.
- Number of prophylactic interventions matched to risk level.
Prophylactic medications
- 5-HT3 antagonists — ondansetron, palonosetron (most common).
- Steroids — dexamethasone (administered intra-op).
- NK1 antagonists — aprepitant for high-risk patients.
- Dopamine antagonists — droperidol, metoclopramide.
- Antihistamines — for specific cases.
- Multi-modal approach typical.
Anesthesia technique adjustments
- Total intravenous anesthesia (TIVA) with propofol — lower PONV than volatile agents.
- Avoid nitrous oxide where possible.
- Reduce opioid dependence.
- Adequate hydration during surgery.
- Dexmedetomidine adjunct reduces PONV.
Patient preparation
- Adequate fasting but not excessive.
- Hydration up to fasting cutoff.
- Pre-op anxiolytic (carefully chosen).
- Blood glucose stability.
Newer therapies
Palonosetron
- Second-generation 5-HT3 antagonist.
- Longer duration of action than ondansetron.
- Both central and gastrointestinal effects.
- Increasingly used in Korean clinics.
Aprepitant
- NK1 receptor antagonist.
- For high-risk patients.
- Oral formulation taken pre-op.
- Effective for delayed PONV.
Dexmedetomidine
- Alpha-2 agonist.
- Reduces opioid requirement.
- Sedative effects.
- Both bolus and continuous infusion options.
- Modern Korean anesthesia practice.
The 2026 standardized PONV SOP
- Standardized risk-based prophylaxis protocols.
- Recent studies show 29% reduction in PONV with consistent SOP implementation.
- 26% reduction in rescue antiemetic medication needs.
- Korean clinics increasingly adopting standardized approaches.
- Anesthesia teams trained in current evidence.
Patient experience and management
What patients should know
- Communicate motion sickness or PONV history at consultation.
- Pre-op anxiolysis if anxiety prone.
- Expect prophylactic medications during anesthesia.
- Post-op nausea may still occur; rescue available.
- Ginger products and ondansetron lozenges sometimes helpful.
If you experience PONV
- Inform recovery staff promptly.
- Rescue antiemetics available.
- Adequate hydration support.
- Bed rest with head elevation.
- Avoid sudden movements.
- Light sips of water as tolerated.
Risk reduction patient can do
Pre-operatively
- Stay well-hydrated up to fasting cutoff.
- Avoid greasy or heavy meals 24 hours before.
- Avoid alcohol.
- Adequate sleep.
- Manage anxiety (anxiety contributes to PONV).
Post-operatively
- Slowly reintroduce liquids and foods.
- Bland foods initially (toast, crackers).
- Avoid greasy foods.
- Stay seated upright initially.
- Slow head movements.
- Use prescribed antiemetics as directed.
For specific procedures
Facial surgery
- PONV particularly dangerous (incision area near mouth).
- Aggressive prophylaxis warranted.
- Vomit can disrupt facial sutures.
Rhinoplasty
- Nasal packing prevents air swallowing.
- Vomiting may disturb internal sutures.
- Specific positioning post-op.
Body contouring
- Long anesthesia duration increases risk.
- High-dose opioid use common.
- Multi-modal prophylaxis standard.
- Recovery position adjusted to minimize.
Common patient questions
Will I throw up after surgery?
With modern multi-modal prophylaxis, PONV reduced to 5–15% of patients depending on risk. Most patients have mild nausea at most.
What if I\'ve had bad nausea before?
Tell your anesthesia team. They\'ll add aprepitant or other agents and use TIVA. Personal history substantially affects protocol selection.
Will the antiemetics make me drowsy?
Some agents have sedating effects. Ondansetron typically not sedating. Steroids and 5-HT3 antagonists typically well-tolerated.
How long does PONV last?
Typically resolves within 24–48 hours. Persistent vomiting beyond 48 hours suggests complication and clinic should be contacted.
Can I eat normally same day?
Light foods initially. Bland foods (toast, rice). Avoid greasy foods first day. Gradual return to normal eating over 1–2 days.
For international patients
- Discuss PONV history at consultation.
- Confirm anesthesia plan and prophylactic medications.
- Ginger candies or wristbands as travel adjuncts.
- Plan ground transportation home (no driving).
- Have soft, bland foods accessible at hotel.
- Hydration support available.
- Don\'t schedule activities first 24 hours post-op.
The honest framing
PONV used to be one of the most distressing aspects of cosmetic surgery — particularly for women, non-smokers, and those with prior history. Modern Korean anesthesia practice has dramatically reduced this through risk stratification, multi-modal prophylaxis, and TIVA technique. The patients who get the smoothest recovery are those whose anesthesia teams take PONV seriously, who communicate their personal risk factors, and who follow recovery instructions carefully. The patients whose teams use minimal prophylaxis, or who don\'t share PONV history, may face avoidable post-op distress. Don\'t hesitate to ask about your anesthesia team\'s PONV protocol — it\'s a significant part of your recovery experience.
