Prognosis among patients with out-of-hospital cardiac arrest judged as being caused by deterioration of obstructive pulmonary disease.
OBJECTIVE
To describe the prognosis of patients with out-of-hospital cardiac arrest judged to be caused by the deterioration of obstructive pulmonary disease.


METHODS
All patients in the community of Göteborg Sweden who suffered out-of-hospital cardiac arrest between 1980 and 1992 attended by our emergency medical service and in whom cardiopulmonary resuscitation was initiated.


METHODS
The etiology of cardiac arrest was determined according to clinical history, observations at resuscitation and findings at autopsy.


RESULTS
There were 3434 cardiac arrests of which 130 (4%) were judged to have been caused by deterioration of obstructive pulmonary disease. Of these patients 50% were found in asystole, 40% in pulseless electrical activity, and only 7% in ventricular fibrillation. Among patients with cardiac arrest caused by obstructive pulmonary disease 21 (16%) were hospitalized alive and six (5%) were discharged from hospital. Among patients who developed cardiac arrest after arrival of the ambulance, 16% were discharged from hospital versus 0% among patients who had arrest prior to arrival of the ambulance.


CONCLUSIONS
Among patients with out-of-hospital cardiac arrest caused by deterioration of obstructive pulmonary disease, half were found in asystole. Overall, the survival rate was low. This highlights the importance of effective treatment early in the course of deterioration of obstructive pulmonary disease in order to avoid cardiac arrest.
