The Canadian Collaborative Acute Pain Initiative, established in 2002, is a voluntary, multidisciplinary consortium of acute pain health professionals from across Canada whose goal is to improve acute pain management through discussion and consensus. The group met in January 2002 to define strategic areas related to the treatment of acute pain. ⋯ In November 2002, a second meeting was held to develop objectives and recommendations for the management of acute pain based on the defined areas. The outcome of these discussions is summarized in this paper.

Recent experiments have shown that transcranial electrical stimulation significantly increases the potency and duration of the analgesic effects of opioids in humans and rats. In the present study, the influence of transcranial electrical stimulation (TCES) on the analgesic effect of remifentanil hydrochloride (HCl) in rats was determined. ⋯ TCES markedly increased the duration and analgesic potency of remifentanil HCl in rats. This effect appeared to be related to the release of enkephalins from brain structures, thus enhancing opioid analgesia.

Chronic pain syndromes are associated with alterations in sleep continuity and sleep architecture. One perspective of this relationship, which has not received much attention to date, is that disturbances of sleep affect pain. To fathom this direction of cause, experimental human and animal studies on the effects of sleep deprivation on pain processing were reviewed. ⋯ Furthermore, sleep deprivation can counteract analgesic effects of pharmacological treatments involving opioidergic and serotoninergic mechanisms of action. The heterogeneity of the human data and the exclusive interest in rapid eye movement sleep deprivation in animals so far do not allow us to draw firm conclusions as to whether the hyperalgesic effects are due to the deprivation of specific sleep stages or whether they result from a generalized disruption of sleep continuity. The significance of opioidergic and serotoninergic processes as mediating mechanisms of the hyperalgesic changes produced by sleep deprivation are discussed.

There are many potential barriers to adequate cancer pain management, including lack of physician education and prescription monitoring programs. The authors surveyed physicians about their specific knowledge of pain management and the effects of the regulation of opioids on their prescribing practices. ⋯ The details of opioid prescribing are crucial areas to target education for cancer pain management. The surveyed physicians accepted the need for regulation of opioid prescribing with very few being fearful of scrutiny from the College of Physicians and Surgeons of British Columbia. However, the inconvenience of the triplicate prescription pad was more of a barrier to prescribing, it being of concern to 20% of respondents, particularly surgeons and medical specialists.

To explore the attitudes of family physicians (FPs) toward the use of opioids in the management of chronic noncancer pain (CNCP) in the Calgary Health Region (CHR), Calgary, Alberta. ⋯ FPs in the CHR need to increase their comfort level toward opioids in general to adequately manage CNCP. Their lack of comfort may reflect a lack of education or fear of regulatory scrutiny.
