在中风模型中使用大鼠的许多研究未能转化为成功的人类临床试验。中风治疗学术行业圆桌会议(STAIR)已经制定了用于临床前试验的啮齿动物中风模型指南,以促进动物研究成功转化为人类研究。这些指南还强调了麻醉和监测技术的重要性。这篇文献综述的目的是记录麻醉方案(即,代理商的选择,通风方式,自2009年STAIR指南发布以来,对生理支持和监测)进行了修订。从PubMed数据库中随机选择了许多描述2005年和2015年在成年大鼠中使用中风模型的文章,并分析了以下参数:进行研究的国家,使用的大鼠品系,中风诱导技术,麻醉剂的诱导和维持,插管和通气模式,监测技术,控制体温,血管通路,静脉输液和镇痛药。对于每个参数(stroke,归纳法,维护,监测),我们使用精确的卡方检验来确定比例是否在一年之间存在显著差异,并对p值进行多重比较校正.对每个参数使用精确的P检验以比较每个值的频率分布,然后进行Bonferroni检验。显著水平设定在<0.05。结果表明,在2005年至2015年之间,麻醉和监测技术的差异很小。2015年,在中国进行的研究明显增多,使用异氟烷和一氧化二氮的研究明显减少。最引人注目的发现是,2005年和2015年的所有研究中,绝大多数都没有报告使用通气;血气测量,潮气末二氧化碳浓度,或血压;或给予静脉输液或镇痛药。对2015年发表的文章的回顾表明,STAIR指南似乎对实验性中风诱导大鼠的麻醉和监测技术没有影响。尽管2009年发布了上述指南。
Numerous studies using rats in stroke models have failed to translate into successful clinical trials in humans. The Stroke Therapy Academic Industry Roundtable (STAIR) has produced
guidelines on the rodent stroke model for preclinical trials in order to promote the successful translation of animal to human studies. These
guidelines also underline the importance of anaesthetic and monitoring techniques. The aim of this literature review is to document whether anaesthesia protocols (i.e., choice of agents, mode of ventilation, physiological support and monitoring) have been amended since the publication of the STAIR
guidelines in 2009. A number of articles describing the use of a stroke model in adult rats from the years 2005 and 2015 were randomly selected from the PubMed database and analysed for the following parameters: country where the study was performed, strain of rats used, technique of stroke induction, anaesthetic agent for induction and maintenance, mode of intubation and ventilation, monitoring techniques, control of body temperature, vascular accesses, and administration of intravenous fluids and analgesics. For each parameter (stroke, induction, maintenance, monitoring), exact chi-square tests were used to determine whether or not proportions were significantly different across year and p values were corrected for multiple comparisons. An exact p-test was used for each parameter to compare the frequency distribution of each value followed by a Bonferroni test. The level of significant set at < 0.05. Results show that there were very few differences in the anaesthetic and monitoring techniques used between 2005 and 2015. In 2015, significantly more studies were performed in China and significantly fewer studies used isoflurane and nitrous oxide. The most striking finding is that the vast majority of all the studies from both 2005 and 2015 did not report the use of ventilation; measurement of blood gases, end-tidal carbon dioxide concentration, or blood pressure; or administration of intravenous fluids or analgesics. The review of articles published in 2015 showed that the STAIR
guidelines appear to have had no effect on the anaesthetic and monitoring techniques in rats undergoing experimental stroke induction, despite the publication of said
guidelines in 2009.
