Patient-Controlled Analgesia (PCA)

Patient-Controlled Analgesia (PCA) is a method of pain management that allows patients to safely control their pain relief by administering small doses of medication through a pump, usually via an IV. The device is programmed to prevent overdose by setting limits on how much or how often medication can be given. Patients can activate the pump with a button whenever they feel pain, enabling timely and personalized pain control. PCA provides convenience, reduces reliance on healthcare staff for pain medication, and helps patients achieve better comfort during recovery.
