Review[Treatment of pain in advanced tumors in the area of the head and neck].
Different mechanisms of pain development and strategies of pain treatment are briefly described as an introduction. Since medicaments are preferentially used for the treatment of cancer pain, pharmacology of analgesics and principles of analgetic therapy are pointed out in more detail. Based on own experiences, a stepwise schedule for the treatment of pain in patients with advanced head and neck cancer is presented.

Parenterally administered narcotic analgesics are a critically important part of therapy for the patient with acute myocardial ischemic syndromes. These agents are very effective and, when used with appropriate caution and monitoring, are also generally safe. They not only relieve the sensation of severe pain but also reduce the effective and physiologic reaction to pain and thus reduce patient anxiety. ⋯ Thus, the hemodynamic effects of these agents may be quite different in patients with active pain during a period of acute ischemia, or in patients that are hemodynamically unstable. Hemodynamic studies during these acute settings, however, are extremely difficult to perform because the patient's acute distress mandates rapid administration of an analgesic agent prior to the institution of invasive monitoring. With these cautions relating to data interpretation in mind, it is still possible to make certain recommendations regarding the use of analgesic therapy in acute MI.(ABSTRACT TRUNCATED AT 250 WORDS)

Patient-controlled analgesia (PCA) provides improved titration of analgesic drugs, thereby minimizing individual pharmacokinetic and pharmacodynamic differences. Patient-controlled analgesia decreases patient anxiety resulting from delays in receiving pain-relieving medication and from the slow onset of analgesic action when these drugs are administered either intramuscularly or in the extradural space. ⋯ The potential for overdose can be minimized if small bolus doses are used with a mandatory lockout interval between successive doses. Finally, studies of the cost-effectiveness of PCA therapy are important if this therapeutic approach is to achieve more widespread acceptance.
