The document addresses the risks and safety concerns associated with patient-controlled analgesia (PCA), highlighting that PCA errors occur predominantly in the post-anesthesia care unit (PACU) and are often due to programming mistakes. It emphasizes the need for all RNs in surgical departments to be trained in PCA and suggests improvements like eliminating paper documentation in favor of electronic systems. The conclusion advocates for better monitoring practices and thorough documentation to enhance patient safety and minimize medication errors.
