小儿耳鼻喉手术麻醉的新进展 总被引:2,自引:0,他引:2
因小儿耳鼻喉手术刺激强,时间短,且常与气道相关,故麻醉的控制有一定难度,现对国内外现阶段小儿耳鼻喉手术麻醉的改良方法及新观点进行评述,以期对临床工作有较好的指导意义。 相似文献

Thirty-two children with malaria were admitted to Dudley Road Hospital, Birmingham, in the 1970s. None was admitted before 1974 and there was a rapid increase after that. All the infections were due to Plasmodium vivax and occurred in children of Asian immigrant families who had been born in or had visited India or Pakistan apart from one infant born in England who acquired the disease transplacentally. All presented within 12 months of entering or re-entering the United Kingdom. The clinical features of the 32 patients have been analysed and it is suggested that more effort should be made to educate travellers about the need for anti-malarial chemoprophylaxis and the necessity to continue it for one month after return. 相似文献

大鼠脑出血灶周围星形胶质细胞内糖原含量的变化 总被引:1,自引:0,他引:1
目的:研究脑出血后局部超微结构的变化,探讨脑出血的病理生理过程,为临床治疗提供理论依据.方法:健康雄性SD大鼠4只,随机等分为实验组和对照组.实验组采用细菌胶原酶注射制作纹状体脑出血模型,对照组采用相同方法在相应部位注入等体积生理盐水,采用透射电镜观察脑出血后24h病变局部及其周围和对照组超微结构的变化和糖原的水平变化.结果:电镜观察到在脑出血动物出血灶周围区,不同类型的细胞内均可见到各种各样的超微结构改变.最为醒目的是在脑内血肿周围星形胶质细胞胞质和突起内有大量的糖原颗粒聚集,尤其在毛细血管周围的胶质细胞突起内非常明显;小胶质细胞和少突胶质细胞内均未发现明显糖原颗粒存在.在生理盐水对照组动物,相应部位的各种细胞的超微结构正常;而且神经元、各种胶质细胞和毛细血管内皮细胞内均无明显糖原颗粒聚集.结论:脑出血周围糖原含量增高,局部存在明显的糖代谢障碍. 相似文献

CONTEXT AND OBJECTIVE: The choice of an antihypertensive drug is based on several criteria and specific situations give rise to doubt and controversy. The aim here was to evaluate physicians approaches towards treatment with antihypertensive agents in specific situations. DESIGN AND SETTING: Cross-sectional study, at Universidade Federal de S?o Paulo, S?o Paulo. METHODS: A questionnaire was applied during a nephrology meeting to evaluate individual approaches towards each hypothetical clinical situation. The questionnaire consisted of five multiple-choice questions (clinical cases) concerning controversial aspects of antihypertensive therapy. RESULTS: A total of 165 questionnaires were analyzed. Most participants were nephrologists (93.2%). There was a preference for angiotensin-converting enzyme (ACE) inhibitors in at least two of the cases. Only 57.2% of the physicians were correct in choosing beta-blockers as the first-line drugs for patients with ischemic coronary disease. Moreover, 66.2% chose ACE inhibitors as the first-line drugs for patients with chronic kidney disease and proteinuria. About 5% of the physicians did not follow the current recommendations for the use of ACE inhibitors in diabetic patients with microalbuminuria. The most controversial question concerned the first-line drug for advanced chronic kidney disease. Most physicians were correct in choosing calcium channel blockers and avoiding ACE inhibitors in renovascular hypertension in the case of a patient with a single functioning kidney. CONCLUSIONS: Most physicians adopted the correct approach, but some had an alternative strategy for the same situations that was not based on evidence. 相似文献
