Abstract<\/h2>\n\n\n\n

BACKGROUND<\/h3>\n\n\n\n

Out-of-hospital cardiac arrest is a leading cause of death worldwide. Establishing vascular access is critical for administering guideline-recommended drugs during cardiopulmonary resuscitation. Both the intraosseous route and the intravenous route are used routinely, but their comparative effectiveness remains unclear.<\/p>\n\n\n\n

METHODS<\/h3>\n\n\n\n

We conducted a randomized clinical trial to compare the effectiveness of initial attempts at intraosseous or intravenous vascular access in adults who had nontraumatic out-of-hospital cardiac arrest. The primary outcome was a sustained return of spontaneous circulation. Key secondary outcomes were survival at 30 days and survival at 30 days with a favorable neurologic outcome, defined by a score of 0 to 3 on the modified Rankin scale (scores range from 0 to 6, with higher scores indicating greater disability).<\/p>\n\n\n\n

RESULTS<\/h3>\n\n\n\n

Among 1506 patients who underwent randomization, 1479 were included in the primary analysis (731 in the intraosseous-access group and 748 in the intravenous-access group). The successful establishment of vascular access within two attempts occurred in 669 patients (92%) assigned to the intraosseous-access group and in 595 patients (80%) assigned to the intravenous-access group. Sustained return of spontaneous circulation occurred in 221 patients (30%) in the intraosseous-access group and in 214 patients (29%) in the intravenous-access group (risk ratio, 1.06; 95% confidence interval [CI], 0.90 to 1.24; P=0.49). At 30 days, 85 patients (12%) in the intraosseous-access group and 75 patients (10%) in the intravenous-access group were alive (risk ratio, 1.16; 95% CI, 0.87 to 1.56); a favorable neurologic outcome at 30 days occurred in 67 patients (9%) and 59 patients (8%), respectively (risk ratio, 1.16; 95% CI, 0.83 to 1.62). Prespecified adverse events were uncommon.<\/p>\n\n\n\n

CONCLUSIONS<\/h3>\n\n\n\n

There was no significant difference in sustained return of spontaneous circulation between initial intraosseous and intravenous vascular access in adults who had out-of-hospital cardiac arrest.
