Monitoring of Analgesic Component during Anaesthesia

The Monitoring of Analgesic Component during Anaesthesia is indirect and, in essence, of the moment. Under general anaesthesia, analgesia is continually influenced by external stimuli and the administration of analgesic drugs cannot be really separated from anaesthesia: the interaction between analgesia and anaesthesia is inescapable. Physiological methods of monitoring must be used to assess anaesthetic depth as normal reflex methods will not be reliable. Nerve stimulators could be used to assess neuromuscular function objectively during anesthesia. Muscle Relaxants are employed in anaesthesia for muscular relaxation and/or abolition of patient movement. Monitoring of the degree of neuromuscular block is accompanied by delivering an electrical stimulus near a peripheral motor nerve and evaluating the evoked response of the muscle innervated by that nerve. In order to cure pain, a physician must know the quantity of sufferer’s pain exactly. Otherwise, the physician may prescribe a wrong dosage of pain killers; it may lead to side effects. Therefore, it is essential to measure the pain objectively and we need some quantitative indicator of pain. This work aims to verify whether Galvanic Skin Response (GSR) can be used as a valid pain indicator and to analyze the changes in GSR during analgesic condition. The experiments will be done under pain and no-pain conditions on subjects of both the gender in the different age group. The results will show a relation between Pain and GSR and there is a scope for measuring pain objectively using GSR. The subjects do not feel pain during analgesia and GSR is a true indicator of pain.
