ObjectiveThe objective of this study was to analyze the clinical profile of patients
with in-hospital cardiac arrest using the Utstein style.MethodsThis study is an observational, prospective, longitudinal study of patients
with cardiac arrest treated in intensive care units over a period of 1
year.ResultsThe study included 89 patients who underwent cardiopulmonary resuscitation
maneuvers. The cohort was 51.6% male with a mean age 59.0 years. The
episodes occurred during the daytime in 64.6% of cases.
Asystole/bradyarrhythmia was the most frequent initial rhythm (42.7%). Most
patients who exhibited a spontaneous return of circulation experienced
recurrent cardiac arrest, especially within the first 24 hours (61.4%). The
mean time elapsed between hospital admission and the occurrence of cardiac
arrest was 10.3 days, the mean time between cardiac arrest and
cardiopulmonary resuscitation was 0.68 min, the mean time between cardiac
arrest and defibrillation was 7.1 min, and the mean duration of
cardiopulmonary resuscitation was 16.3 min. Associations between gender and
the duration of cardiopulmonary resuscitation (19.2 min in women versus 13.5
min in men, p = 0.02), the duration of cardiopulmonary resuscitation and the
return of spontaneous circulation (10.8 min versus 30.7 min, p < 0.001)
and heart disease and age (60.6 years versus 53.6, p < 0.001) were
identified. The immediate survival rates after cardiac arrest, until
hospital discharge and 6 months after discharge were 71%, 9% and 6%,
respectively.ConclusionsThe main initial rhythm detected was asystole/bradyarrhythmia; the interval
between cardiac arrest and cardiopulmonary resuscitation was short, but
defibrillation was delayed. Women received cardiopulmonary resuscitation for
longer periods than men. The in-hospital survival rate was low.
