As a disease, such as cancer progresses, the pain increases. It is this disease progression and not the body's tolerance, which requires an increase in the morphine dosage. Thou shalt not assume that the patient's pain is caused by the malignant process. Thou shalt take into consideration the patient's feelings. Thou shalt not use the abbreviation p.r.n.
Continuous pain requires regular preventative pain management.
Thou shalt not prescribe inadequate amounts of any analgesic. Thou shalt try nonnarcotic analgesics in the first instances. Thou shalt not be afraid of narcotic analgesics. Thou shalt not limit thy approach simply to the use of analgesics. Thou shalt not be afraid to ask a colleague's advice.
