Pain is a manifestation of various physiological, pathological, and other insults which needs urgent relief. Agents used for pain relief can be associated with side effects related to the drug by itself, class effects (like non-steroidal anti-inflammatory drugs, NSAIDS) or drug–drug interactions, respectively. Whatever be the different clinical settings of patient care, pain must be relieved, with due regard for concerns raised from use of pharmacological agents and also techniques feasible in many circumstances during anesthesia.
