Intravenous or Intraosseous Vascular Access in Cardiac Arrest: An Individual Participant Data Meta-Analysis
Listen to this summary
The authors aimed to compare the effectiveness of intraosseous-first versus intravenous-first vascular access during out-of-hospital cardiac arrest by conducting an individual participant data meta-analysis of randomized trials. Their analysis, which included data from 7,561 patients, found no statistically significant differences in 30-day survival, favorable neurological outcomes, or sustained return of spontaneous circulation between the two access methods. Overall, the findings suggest that both approaches yield similar outcomes in this critical setting.
