目的:系统评价舒适化浅镇静策略(eCASH策略)对重症监护室(ICU)机械通气病人谵妄的干预效果。方法:计算机检索万方数据库、中国知网、维普数据库、中国生物医学文献服务系统、Web of Science、PubMed、EMbase、the Cochrane Library数据...目的:系统评价舒适化浅镇静策略(eCASH策略)对重症监护室(ICU)机械通气病人谵妄的干预效果。方法:计算机检索万方数据库、中国知网、维普数据库、中国生物医学文献服务系统、Web of Science、PubMed、EMbase、the Cochrane Library数据库中关于舒适化浅镇静策略对ICU机械通气病人谵妄干预效果的随机对照试验,检索时限为建库至2022年3月31日。由2名研究者严格按照纳入与排除标准独立进行文献筛选、质量评价、资料提取后,应用RevMan 5.4软件进行Meta分析。结果:共纳入22项随机对照试验。Meta分析结果显示,与常规护理相比,舒适化浅镇静策略能降低ICU机械通气病人谵妄发生率[OR=0.42,95%CI(0.34,0.52),P<0.00001],缓解谵妄持续状态[MD=-1.30,95%CI(-1.48,-1.12),P<0.00001],缩短机械通气时间[SMD=-1.23,95%CI(-1.57,-0.89),P<0.00001]和ICU住院时间[SMD=-1.06,95%CI(-1.27,-0.85),P<0.00001],降低住院死亡和放弃治疗率[OR=0.37,95%CI(0.22,0.60),P<0.0001]。结论:现有证据表明,舒适化浅镇静策略能降低ICU机械通气病人谵妄发生率和住院死亡、放弃治疗率,缓解谵妄持续状态,减少机械通气时间和ICU住院治疗时间。展开更多

While in universities of China, students do not have strong autonomy in English language learning. The author tries to adopt specific meta-cognitive strategies to facilitate students' autonomy in learning by improving learners' capacities in study planning or management, monitoring and evaluating in learning to raise their consciousness and ability in autonomy, and lay a foundation for life-long learning.展开更多
