This study aimed to determine the frequency of prophylactic steroid administration to prevent reintubation after extubation in critically ill patients. We systematically searched MEDLINE, Embase and Cochrane Library for studies regarding the preventive use of multiple doses or single-dose steroids prior to extubation on July 2020 and conducted a network meta-analysis (NMA) to compare these interventions. To assess the risk of bias of each included study, version 2 of the Cochrane risk-of-bias tool for randomized trials was used. Nine randomized control trials comprising 2098 patients with comparisons of the three interventions were included. Use of multiple doses and single doses of intravenous steroids administration showed a significantly lower rate of reintubation compared with placebo (odds ratio [OR]: 0.43, 95% confidence interval [CI]: 0.25–0.72; OR: 0.31, 95% CI: 0.14–0.69). However, the comparison between multiple doses and single doses showed no significant differences (OR: 1.22, 95% CI: 0.32–4.74). According to the surface under the cumulative ranking curve statistic, the treatments should be ranked as follows: single dose (87.1%), high dose (62.8%) and placebo (0.1%). This NMA showed that the multiple doses were not statistically superior to the single dose in lowering the incidence of reintubation after extubation in critically ill patients. Therefore, use of a single-dose steroid can reduce the incidence of reintubation.
