Post-Anesthesia Care, Pain Management, and Recovery
What you must understand
Know the criteria for safe discharge from the post-anesthesia care unit: stable vital signs, adequate oxygenation and ventilation, controlled pain, no ongoing bleeding, and return of protective reflexes. Understand common recovery problems: nausea and vomiting, shivering, hypothermia, airway obstruction, and delayed emergence. Know pain assessment tools and multimodal analgesia (opioids, nonsteroidal agents, local anesthetics, adjuncts). Understand the risks of opioid therapy, including respiratory depression, and the role of monitoring. Recognize post-dural puncture headache and its management. Understand the importance of handoff communication and documentation.
Traps in questions
Questions often present a patient who looks comfortable but has a low respiratory rate-sedation and respiratory depression can be subtle. Another trap is discharging a patient based on time alone rather than criteria. Watch for questions that confuse postoperative nausea and vomiting prevention with treatment, or that ignore multimodal analgesia.
Rule of thumb
Discharge is a criteria-based decision, not a clock-based one. If any criterion is unmet, keep the patient and reassess.
