Document Summary
Pain process: multidimensional, sensory-discriminative, recognition of sensation as painful, motivational-affective, emotional response, behavioural, actions to express or control pain, sociocultural, de(cid:373)ographi(cid:272)s, (cid:272)ulture , profound fx on functioning. Nsaids: block the action of phospholipase, thereby interfering with the production of prostaglandins. Transmission movement of pain impulses from the site of transduction to the brain. Three segments are involved in nociceptive signal transmission: (a) transmission along the nociceptor fibres to the level of the spinal cord, (b) dorsal horn processing, (c) transmission to the thalamus and the cortex. Perception is the recognition, definition, and response to pain by the individual experiencing it. In the brain, nociceptive input is perceived as pain. There is no single, precise location where pain perception occurs. Instead, pain perception involves several brain structures: nursing care, treatment of any noxious stimulus as potentially painful, even in cognitively impaired or comatose patients, who may not respond behaviourally to noxious stimuli.
