Advances in nursing patients with intractable pain.
Caring for patients with prolonged persistent pain remains one of nursing's greatest challenges. Increased knowledge and understanding of pain pathways, however, has enabled new treatments to be incorporated into pain management regimes. Of particular interest has been the association of the N-methyl-D-aspartate (NMDA) receptors with the development of hyperalgesia and 'wind-up'. This review will explore the physiological processes associated with these phenomena, and the use of NMDA receptor antagonists such as ketamine and dextromethorphan to prevent and treat persistent pain. The importance of nurses understanding the modes of action of these drugs will be illustrated through presentation of two case histories.
