Drug Delivery Analgesia
Typical Use
Allow patients to self administer controlled bolus doses of analgesic medication.
Description
A programmable infusion device that permits patients to self administer preset bolus doses of opioid or nonopioid analgesics within safety limits to manage acute postoperative or cancer related pain while reducing delays in analgesia and improving patient satisfaction. PCA pumps include lockout intervals, maximum dose limits, and monitoring protocols to reduce overdose risk, and require patient education, nursing oversight, and respiratory monitoring for safety. Selection of appropriate concentrations, adjunctive multimodal analgesia, and careful patient selection are essential to balance effective pain control with minimization of adverse effects such as respiratory depression.
