AS6.1-3 | Recovery Room Monitoring, Crash Cart Readiness and Complication Management — Summary & Reflection

KEY TAKEAWAYS

The post-anaesthesia care unit provides a monitored bridge between the operating room and the ward, during which patients are physiologically most vulnerable to the residual effects of anaesthetic agents. Structured monitoring — minimum mandatory parameters of pulse oximetry, ECG, NIBP, respiratory rate, consciousness level, pain score, and temperature — combined with the Aldrete Post-Anaesthetic Recovery Score (maximum 10; discharge threshold ≥9) provides the systematic framework for identifying deterioration and deciding readiness for discharge. The crash cart must be immediately accessible, sealed after every shift check, and contain a comprehensive set of airway equipment (BVM, Guedel airways, laryngoscope, ETTs), ACLS drugs (adrenaline, atropine, amiodarone, sodium bicarbonate, dextrose, naloxone), and vascular access supplies. The physiological basis of PACU vulnerability spans residual respiratory depression from volatile agents and opioids, reduced pharyngeal muscle tone from NMBAs, cardiovascular instability from anaesthetic vasodilation and the emergence catecholamine surge, and near-universal post-operative hypothermia. Common complications — airway obstruction (jaw thrust + airway adjunct), laryngospasm (CPAP + Larson manoeuvre + titrated suxamethonium), bronchospasm (salbutamol), opioid-induced respiratory depression (titrated naloxone 0.1–0.2 mg increments), post-operative hypertension (analgesia + treat cause), hypotension (fluid bolus + vasopressors), delayed emergence (structured cause assessment), emergence agitation (rule out hypoxia first), PONV (ondansetron), and hypothermia (active warming) — are all predictable and treatable when recognised early.

REFLECT

Consider a scenario where you are the first doctor called to a recovery room at 10 pm when the anaesthetist is briefly unavailable. What are the five things you would check in the first 60 seconds? How would you differentiate between opioid-induced respiratory depression and laryngospasm at the bedside, and why does that distinction matter for your initial pharmacological response? Think about the crash cart: if you had to draw up naloxone and you had never opened that drawer before, what is the one thing on the crash cart checklist that tells you the cart has been fully and correctly restocked since its last use? Finally, when you hand over your patient to the ward nurse, what is the single most important piece of information you must communicate about analgesic management — and what happens to the patient overnight if you omit it?
