Morphine consumption for medical purposes in Japan showed a 17-fold increase between 1979 and 1989, due to increased use in cancer pain management. This increase is a reflection of the improving attitude of the health care professionals and health policy makers towards narcotics use. The WHO Cancer Pain Relief Programme has ultimately become the basis for a national cancer pain relief programme. The Ministry of Health and Welfare amended the Narcotics and Psychotropics Control Law in 1990, to improve accessibility of morphine preparations to cancer patients with pain, and edited four manuals for palliative care, that include guidelines on cancer pain relief, and legislative management of narcotics use in hospital, clinic and pharmacy.

Systemic and renal haemodynamic and functional indices were measured in 15 anaesthetised pigs during systemic sepsis induced by faecal peritonitis. Five animals were assigned to maintenance of cardiac output (CO) at baseline, pre-infection values throughout the study (controls n = 5). In the remaining 10 animals, CO was increased by 25% prior to induction of sepsis and maintained at this level for the duration of the study using volume expansion with intravenous colloid and an infusion of either 20 micrograms/kg/min dobutamine (n = 5) or placebo (n = 5). ⋯ In the dobutamine group systemic oxygen uptake (VO2) increased from 173 +/- 30 to 277 +/- 73 ml/min (P less than 0.05), however this resulted in a decrease in renal DO2 (20 +/- 9 to 10 +/- 2 ml/min P less than 0.05) and there was no equivalent rise in renal VO2 (3.3 +/- 1.6 to 3.2 +/- 1.5 ml/min). There was however no significant difference in the effect on renal function of the three management protocols. Agents used to increase cardiac output during systemic sepsis may result in significantly different effects on the renal vascular bed which are not revealed by the measurement of systemic indices alone.

Pain management is an integral component of comprehensive cancer care. The combined goals of optimal comfort and optimal function require a working understanding of how pain therapy interacts with cancer and cancer therapy. The two main aspects of cancer which affect pain management are the cancer's treatability and its non-pain pathophysiology. ⋯ Pain therapy can impair cancer therapy by augmenting or complicating cancer therapy's adverse effects. Pain therapy can enhance cancer therapy by improving organ function and patient performance status permitting previously limited or contraindicated cancer therapies to be given. Five case studies are presented to illustrate how effective integration of pain management into comprehensive cancer care is mandatory for optimal care of cancer patients and their families.
