Episode notes
Value Of Repeated Viva Practice
- Susanna found repeated viva practice confronting but highly valuable and recommends volunteering for mock vivas.
- Lahiru and Dan agree varied, repeated practice helps normalise exam-style questioning.
Practical Intraoperative Antiemetic Strategy
- Assess PONV risk and give one or two antiemetics based on risk factors.
- Use dexamethasone (if no contraindication) and ondansetron as a typical intraoperative combo.
Managing Serotonin Syndrome
- Stop the offending drugs and provide supportive care for serotonin syndrome, using benzodiazepines for agitation and airway support if needed.
- Consider cyproheptadine for refractory severe cases after stabilization, though evidence is limited.
