Cardiopulmonary resuscitation in critically ill neurologic-neurosurgical patients

To establish the rate of successful cardiopulmonary resuscitation (CPR) and to study outcome predictors in patients who experienced in-hospital cardiac arrest after being admitted to the neurologic-neurosurgical intensive care unit (ICU) with a primary neurologic diagnosis.

We identified patients admitted to the neurologic-neurosurgical ICU between 1994 and 2001 who experienced in-hospital cardiac arrest and received CPR. Functional outcome was assessed using the modified Rankin scale.

During the study period, 38 consecutive patients experienced in-hospital cardiac arrest and received CPR. The median age of the patients was 65 years (range, 16-81 years), and the mean interval from admission to CPR was 12 days (range, 3 hours to 47 days). Acute intracranial disease was present in 32 patients (84%). Twenty-one patients (55%) were in the ICU at the time of the cardiac arrest; cardiac arrests in the wards occurred at a mean interval of 9 days (range, 1-45 days) after ICU discharge. Cardiopulmonary resuscitation achieved return of spontaneous circulation in 23 patients (61%). Seven patients (18%) were discharged from the hospital, 5 of whom later achieved a modified Rankin scale score of 2 or lower. Cardiac arrest after a deteriorating clinical course resulted in uniformly fatal outcomes. Duration of CPR shorter than 5 minutes and CPR in the ICU were associated with survival and good functional recovery.

Cardiopulmonary resuscitation is a worthwhile procedure in severely ill neurologic-neurosurgical patients, regardless of the patient's age. However, the outcome after CPR appears much worse in patients with a prior deteriorating clinical course.
