The importance of the liver in the metabolism of analgesic agents has long been recognized. Important changes in the elimination of these drugs may occur in critically ill patients. Changes in liver blood flow are particularly important since hypotension, anesthesia and surgery [1], trauma, sepsis, hypoxia and possibly inotropic therapy lead to significant alterations, resulting in large changes in the clearance of these drugs. To date there has been little systematic study of commonly used drugs in acute hepatic insufficiency, a common accompaniment of serious illness. Furthermore the concurrent administration of some of the many drugs used to treat such illness including benzodiazepines, cimetidine etc. may interfere with the liver enzymatic activity, decreasing or increasing the rate of metabolism. Of all of the analgesics in common use in the critically ill, morphine is the commonest in use worldwide. This review will predominately concentrate on the altered metabolism of morphine in critically ill humans although the newer synthetic opiates will also be discussed.
