Rib fractures after chest compressions for cardiac arrest: retrospective analysis of the AfterROSC1 and AfterROSC2 multicenter databases

Résumé fourni par la source

Purpose: External chest compressions for resuscitation after out-of-hospital cardiac arrest (OHCA) can cause rib fractures, which are best diagnosed by computed tomography (CT). We assessed the prevalence, management, and associations with outcomes of CT-documented rib fractures in patients with OHCA. Methods: We retrospectively analyzed data collected prospectively at five AfterROSC Network centers in 2020-2023. We included consecutive patients with return of spontaneous circulation and coma after non-traumatic OHCA who underwent CT within 6 h after admission. Rib fractures and other chest-wall injuries were recorded. Associations with the day-90 functional outcome were sought. Analgesic treatment was compared between patients with 0-2 vs. ≥3 rib fractures. Results: = 0.003). Analgesic therapy was not significantly different between patients with 0-2 and ≥3 rib fractures. Conclusions: Rib fractures related to chest compressions are common in OHCA survivors. Having ≥3 rib fractures was associated with a poorer prognosis after adjustment on cardiac-arrest characteristics. The management of pain related to rib fractures may require reappraisal.
