AS4.6-7 | Day Care Anaesthesia and Anaesthesia Outside the Operating Room — Summary & Reflection

KEY TAKEAWAYS

Day care anaesthesia (AS4.6) requires: patient selection (ASA I–III stable; appropriate procedure; social suitability — adult escort, phone, proximity); fast-track pharmacology (propofol TIVA + remifentanil + multimodal analgesia; LMA over ETT for suitable cases; avoidance of long-acting opioids); aggressive PONV prophylaxis (Apfel score → ondansetron + dexamethasone; propofol reduces PONV vs volatile); structured discharge criteria (fully awake, pain controlled, no PONV, able to mobilise, confirmed escort). NORA (AS4.7) principles: replicate operating theatre safety standards in the remote location; ensure piped + cylinder O₂, suction, capnography, full monitoring, trained staff, and rehearsed emergency protocol; MRI requires MR-safe/conditional equipment only — all ferromagnetic items excluded from the magnetic field. The leading NORA-specific risk is the absence of backup resources when a complication occurs in an unfamiliar environment. The solution is systematic preparation, not familiarity or assumption.

REFLECT

A 72-year-old woman with moderate aortic stenosis (valve area 1.0 cm², mean gradient 32 mmHg), NYHA Class II heart failure, and a BMI of 38 is listed for elective colonoscopy at a district hospital endoscopy unit staffed by nurses with basic life support training. The gastroenterologist wants propofol sedation. No anaesthesiologist is regularly posted to this unit. Reflecting on the principles you have learned in this SDL: (1) What are the specific risk factors in this patient that make sedation in an unmonitored environment dangerous? (2) What minimum requirements must be in place before you, as the anaesthesiologist, agree to provide sedation? (3) If the required standards cannot be met in the endoscopy unit, what would you recommend instead — and on what clinical grounds? This scenario encapsulates the ethical and professional responsibility that comes with providing anaesthesia in resource-limited NORA settings.
