Patient-controlled analgesia after coronary artery bypass grafting

Patient-controlled analgesia is a method of pain control that allows the patient to self-administer opioid medication as and when it is needed. Pain is a personal experience and one pain-relieving intervention may not be effective for all patients. This article reviews the literature on patient-controlled analgesia, particularly with reference to patients after coronary artery bypass grafting. Pain policies and education programmes need to be proactive in addressing staff and patient gaps in knowledge and misconceptions about pain assessment and management. Nurses need to appreciate the nature and importance of research in promoting a more critical approach to patient care and the development of quality nursing practice.
