PURPOSE: Acute pain management services (APMS) evolved in response to the desire for improved management of postoperative pain. The management of postoperative pain received formal support from international organizations over the past decade and by 1993 half of the Canadian university-affiliated teaching hospitals had implemented an APMS. The purpose of this survey was to describe APMSs in Canadian academic institutions, with specific emphasis on postoperative analgesics, new analgesic methods, training and research. METHODS: Between June 2000 and January 2001, 62 Canadian hospitals affiliated with the 16 Canadian university anesthesiology departments were sent a postal questionnaire. RESULTS: Fifty of the 62 respondents returned a completed questionnaire representing a response rate of 81%. Eighty percent of the hospitals surveyed had at least 200 beds, 90% (45) had implemented an APMS. Anesthesiology was primarily responsible in all 45 hospitals with an APMS. The results presented are based on the 45 centres with an APMS. CONCLUSION: Since the early 1990s the percent of Canadian academic hospitals with an APMS has increased from 53% to 92%. These figures are comparable to the United States. Greater collaboration from nursing and pharmacy, mandatory training for medical and nursing students and residents, and a standardized approach to continuous quality improvement remain necessary. 相似文献
Throughout history, the heart has been associated not only with its life-sustaining function but also with its close ties to the human emotions. In this literature and internet review, we attempt to gather and organize information from both of these perspectives as they relate to the heart in the following 11 categories: (1) fun facts, (2) medical photography, (3) history, (4) languages (etymology), (5) nonmedical English expressions, (6) death, (7) the arts, (8) movie titles, (9) song titles, (10) Shakespeare, and (11) the Bible. Part 1 (previously published) covered the first five topics, and Part 2 will cover the last six topics. These data may be useful to those who are engaged in teaching about the cardiovascular system. 相似文献
Absidia corymbifera infection in a healthy individual is rare. Most of the infection occurs in immunocompromised patients or diabetic patients. Cutaneous and subcutaneous mucormycosis have been increasingly reported in the literature as a result of massive trauma with contaminated wounds. We present a case of cutaneous mucormycosis in a healthy, young patient after surgical amputation for a crush injury of the leg. We also highlight the importance of the high index of clinical suspicion in the diagnosis and treatment of this fungal infection in the hype of methicillin-resistant Staphylococcus aureus (MRSA) infection in hospital setting these days. Despite an initial life-saving amputation, it was inadequate to ensure the eradication of A. corymbifera infection. A second amputation was required with parenteral liposomal amphotericin B to achieve a satisfactory cure. 相似文献
Background: A major effect of general anesthesia is lack of response in the presence of a noxious stimulus. Anesthetic depression of spinal sensory neuronal responses to noxious stimuli is likely to contribute to that essential general anesthetic action. The authors tested the hypothesis that [gamma]-aminobutyric acid receptor type A (GABAA) and strychnine-sensitive glycine receptor systems mediate halothane depression of spinal sensory neuronal responses to noxious stimuli.
Methods: Extracellular activity of single spinal dorsal horn wide dynamic range (WDR) neurons was recorded in decerebrate, spinal cord transected rats. Neuronal responses to noxious (thermal and mechanical) and nonnoxious stimuli were examined in the drug-free state. Subsequently, cumulative doses (0.1-2.0 mg/kg) of bicuculline (GABAA antagonist) or strychnine (glycine antagonist) were administered intravenously in the absence or presence of 1 minimum alveolar concentration (MAC) of halothane.
Results: Halothane, 1.1%, depressed the response of WDR neurons to both forms of noxious stimuli. Antagonists, by themselves, had no effect on noxiously evoked activity. However, bicuculline and strychnine (maximum cumulative dose, 2.0 mg/kg) partially but significantly reversed the halothane depression of noxiously evoked activity. Similar results were seen with most, but not all, forms of nonnoxiously evoked activity. In the absence of halothane, strychnine significantly increased neuronal responses to low threshold receptive field brushing. 相似文献
