PACU Complications: Navigating the 'Home Stretch'

The Exam Doesn't End at Extubation

You’ve probably seen the relief on a candidate's face when the surgical part of the scenario ends. But if you’re like me, you know the PACU is where the true complications hide. What actually ends up happening is they hit you with a delayed emergence or post-op agitation just when you think you're safe.

Rule Out the Killers

If a patient is agitated, the reality is it’s probably pain, but on the boards, you must rule out hypoxia first. "I will immediately check the pulse-ox and ensure adequate ventilation."

Delayed Emergence Logic

Categorize your differential:

• Metabolic: Hypoglycemia, hyponatremia.
• Pharmacologic: Residual Neuromuscular Blockade (NMB), opioids, volatile anesthetics.
• Neurologic: Intraoperative stroke or seizure.

Example: Negative Pressure Pulmonary Edema (NPPE)

Patient bites the tube, gets extubated, and starts to desaturate with pink frothy sputum. Don't hesitate. "I will apply Continuous Positive Airway Pressure (CPAP) with 100% O2 to oppose the hydrostatic pressure."

FAQs: PACU Scenarios

Should I re-intubate an agitated patient?

Only if they are failing to protect their airway or are profoundly hypoxic. Otherwise, treat the underlying cause (pain, full bladder, hypoxia).

Conclusion

Don't relax until the scenario completely ends. Stay vigilant and rule out life-threatening causes of PACU instability systematically.
