Vascular access by paramedics during cardiopulmonary resuscitation in out-of-hospital cardiac arrest: A retrospective study of insertion success rates and survival outcomes of intravenous versus intraosseous route

Key Points

• Successful vascular access correlates with improved survival rates during cardiopulmonary resuscitation.
• Insertion success rates were notably higher for intravenous routes compared to intraosseous methods.
• Retrospective analysis of data from out-of-hospital cardiac arrest incidents was performed over a defined timeframe.
• Further investigation is necessary to optimize vascular access strategies in emergency medical contexts.
