Freedom from cancer pain is one of the four priorities of the WHO Cancer Control Programme. Every day 3.5 million people are suffering from cancer pain, and most do not receive adequate relief. A lack of training in cancer pain management at most nursing and medical schools is the principal reason for this, coupled with limited availability of oral strong opioids in many countries. ⋯ Psychological dependence does not occur in patients receiving opioids for pain relief. 11. Patients receiving analgesics must be carefully monitored. 12. Teamwork is necessary for good results.

Neuropsychological and neurophysiological investigations indicate that a 30-40 Hz oscillatory brain mechanism is necessary for the adequate uptake and processing of elementary successive sensory events. An oscillatory component of that particular frequency range can be observed in the mid-latency auditory evoked potential (MLAEP). It is suppressed under non-specific anesthetic agents (agents not acting on specific structures of the brain or receptors). ⋯ By Fast-Fourier Transform-analysis corresponding power spectra were calculated to analyze energy portions of the AEP frequency components. In the awake state AEP showed an oscillatory component between 20- and 100-ms post-stimulus latency. Corresponding power spectra indicated a dominant 30-40 Hz frequency.(ABSTRACT TRUNCATED AT 250 WORDS)

Research has indicated that approximately three-quarters of patients in acute care hospitals experience moderate to severe pain. It is thought that inadequately controlled pain is the result of poor clinical performance on the part of nurses and physicians. Faculty knowledge about pain mechanisms and pharmacology have been targeted as the source of their poor performance. ⋯ This study examined some of the misconceptions nurses have about addiction and pain management. A number of fallacies were identified. These included a very strong opiophobia or fallacy about addiction liability of narcotics even under conditions of normal hospital use.

Epidural sufentanil was administered to 57 women after Caesarean section, under epidural anaesthesia, to provide postoperative analgesia. Each patient received a 30 micrograms dose at the first complaint of pain and this dose was repeated when pain recurred. Epinephrine (1:200,000) was added to the local anaesthetic, sufentanil, both, or neither. ⋯ Respiratory depression, as defined by a respiratory rate less than 10 bpm, was not observed. A number of patients noted a transient period of euphoria 5-8 min after administration of the epidural sufentanil. The authors feel that epidural sufentanil provides satisfactory analgesia after Caesarean section, but the brief duration of action and the high incidence of drowsiness limit its acceptability for routine use in obstetric patients.
