Patient-Controlled Analgesia Pumps Have Low Device-Related Error Rates
Device-related errors were categorized according to mechanism of error and related clinical outcomes.
Underflow was the most frequent device error; however, overflow carried more risks inherent with opioid analgesics. In attempting to balance these considerations, the authors noted, “Underflow errors should be considered as seriously as overflow errors. Taken together, effective postoperative pain management requires a balance between safety issues, mainly from overflow, and satisfaction issues, mainly from underflow.”
