Red flags

  • No responsible escort and overnight support = not day-case, regardless of the surgery sticker.
  • Severe untreated OSA plus opioid-heavy technique is a post-discharge death pathway.
  • PADSS score is necessary but not sufficient — clinical judgement and procedure-specific advice still required.
  • Uncontrolled pain, PONV, or bleeding at discharge is failed ambulatory care.
  • Office-based anaesthesia without emergency airway and transfer plans is reckless.

The one-line answer

Day-case anaesthesia is a pathway, not a sticker (taught ambulatory pathway). Book only patients with a safe home plan, anaesthetise with a short-acting opioid-sparing technique, kill postoperative nausea and vomiting proactively, discharge on a scored checklist plus clinical judgement, and admit early the moment discharge would export risk.[5][1]

Meet the patient

A 54-year-old woman, ASA 2, arrives for a laparoscopic cholecystectomy on the day-case list (taught vignette). She has a responsible partner, lives ten minutes from the hospital, and scores three Apfel factors. The plan writes itself — and the fellowship exam wants to hear you write it.[1]

The two questions that decide every day case are the two juniors forget: is this patient safe to send home alone tonight? and have I built the anaesthetic around waking up comfortable, warm, and not vomiting? Hold those two and the whole pathway slots into place (taught framing).[5][1]
