Background: The use of β2 agonist as an intervention for acute lung injury (ALI) and ARDS patients is controversial, so we performed a systematic review and meta-analysis of the published randomized controlled trials of using β2 agonists to improve outcomes (mortality and ventilator free days) among patients with ALI/ARDS.
Methods: A comprehensive search of 7 major databases (Ovid MEDLINE In-Process and other non-indexed citations, Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials (CENTRAL), Ovid Cochrane Database of Systematic Reviews, Web of Science, and Scopus) for randomized controlled trials using β2 agonists for ALI from their origin to March 2013 was conducted. The effect size was measured by relative risk for dichotomous outcomes, and mean difference for continuous outcomes, with 95% CI.
Objective: To perform a systematic review and meta-analysis of clinical trials evaluating the efficacy and safety of midodrine in orthostatic hypotension (OH).
Methods: We searched major databases and related conference proceedings through June 30, 2012. Two reviewers independently selected studies and extracted data.
