Vasopressin and glucocorticoids both improve outcomes of in-hospital cardiac arrest: Study
Vasopressin and glucocorticoids both improved the return of spontaneous circulation among adults with in-hospital cardiac arrest, according to a recent study published in Resuscitation.
A group of researchers conducted a study to perform a systematic review and individual participant data meta-analysis of vasopressin and glucocorticoids for the treatment of cardiac arrest.
The PRISMA-IPD guidelines were followed. The researchers searched Medline, Embase, and the Cochrane Library for randomized trials comparing vasopressin and glucocorticoids to placebo during cardiac arrest. The population included adults with cardiac arrest in any setting. Pairs of investigators reviewed studies for relevance, extracted data, and assessed the risk of bias. Meta-analyses were conducted using individual participant data. A Bayesian framework was used to estimate posterior treatment effects assuming various prior beliefs. The certainty of the evidence was evaluated using GRADE.
Results of the study are:
Three trials were identified including adult in-hospital cardiac arrests only. Individual participant data were obtained from all trials yielding a total of 869 patients. There was some heterogeneity in post-cardiac arrest interventions between the trials. The results favoured vasopressin and glucocorticoids for return of spontaneous circulation (odds ratio: 2.09, 95%CI: 1.54 to 2.84, moderate certainty). Estimates for survival at discharge (odds ratio: 1.39, 95%CI: 0.90 to 2.14, low certainty) and favourable neurological outcome (odds ratio: 1.64, 95%CI, 0.99 to 2.72, low certainty) were more uncertain. The Bayesian estimates for return of spontaneous circulation were consistent with the primary analyses, whereas the estimates for survival at discharge and favourable neurological outcome were more dependent on the prior belief.
Thus, the researchers concluded that among adults with in-hospital cardiac arrest, vasopressin and glucocorticoids compared to placebo, improved return of spontaneous circulation. Larger trials are needed to determine whether there is an effect on longer-term outcomes.
