A patient controlled analgesia (PCA) pump malfunction led to a morphine overdose and respiratory arrest. Device modifications and rigorous vigilance are crucial to prevent similar incidents.

Area of Science:

  • Anesthesiology
  • Pharmacology
  • Medical Device Safety

Background:

  • Patient-controlled analgesia (PCA) is commonly used for postoperative pain management.
  • The Abbott Gemstar pump was utilized for morphine delivery after nephrectomy.

Observation:

  • A 67-year-old female experienced respiratory arrest minutes after PCA pump connection.
  • The event was caused by a morphine overdose due to uncontrolled, gravity-driven free flow from the pump.

Findings:

  • The overdose resulted from a misconnection bypassing the anti-siphon valve and an improperly secured PCA cassette.
  • The patient was resuscitated with an uneventful recovery.

Implications:

  • This case highlights critical patient safety risks associated with PCA devices.

  • Modifications to the pump's tubing and software were implemented by the manufacturer.
  • Continuous vigilance is essential, even with routine use of PCA technology.
