Sammanfattning (abstract):
AIM: To describe all patients treated for out-of-hospital cardiac arrest (OHCA) according to the Utstein criteria and their characteristics and outcome with emphasis on whether they were available for early intervention trials. DESIGN: Retrospective analysis of a study where data were collected prospectively. SETTING: The Municipality of Goteborg/Molndal in Sweden. PATIENTS: All patients suffering from out-of-hospital cardiac arrest in the Municipality of Goteborg/Molndal in whom cardiopulmonary resuscitation (CPR) was attempted between May 2003 and May 2005. INTERVENTIONS: Part of the study cohort, i.e. patients with a witnessed, non-traumatic, out-of-hospital cardiac arrest were distributed (cluster) to mechanical (LUCAS) or manual chest compression. RESULTS: The overall survival to discharge from hospital among the 508 patients was 8.5%. The corresponding value for non-cardiac cases was 5.1% and for cardiac cases if crew witnessed 16.1%, bystander witnessed 12.7% and non-witnessed 1.4%. Fifty-nine percent of the patients fulfilled the inclusion criteria for the trial and had no exclusion criteria and 9.7% of these survived to discharge. Ten percent of patients fulfilled the inclusion criteria but were excluded and 20.4% survived to discharge. Thirty-one percent of patients did not fulfil the inclusion criteria and 2.5% survived. Among patients included in the LUCAS group, many of the survivors, 10/13 (77%), experienced a rapid return of spontaneous circulation (ROSC) before the application of the device. CONCLUSION: Among patients with OHCA in whom CPR was started 8.5% survived to hospital discharge and 59% were theoretically available for an early intervention trial. These patients have a different outcome compared with patients not available. However, among those available, the majority of survivors had a rapid ROSC before the application of the intervention (LUCAS). This raises concerns about the potential for early intervention trials to improve outcome after OHCA.
