Overview

Objective:
To assess the impact of therapeutic hypothermia on patients’ neurological outcome after out-of- and in-hospital cardiopulmonary resuscitation for shockable and non-shockable rhythms.

Design:
A comparative, non-randomized study.

Setting:
A University Hospital ICU.

Methods:
We compared a group of patients admitted to the ICU following cardiopulmonary resuscitation in 2010 to a group of patients admitted in 2006. Both groups were further divided into two subgroups: resuscitated for shockable and non-shockable rhythms respectively. Neurological outcome was assessed on discharge from the ICU or the hospital by the Glasgow Outcome Scale.

Results:
Compared to 2006, mortality increased in the 2010 subgroups and the number of patients with favourable neurological outcome decreased. In the subgroup of patients receiving out-of-hospital CPR due to VF the mortality increased by 21% and 17% fewer patients were discharged with GOS 4–5. In the subgroup of patients receiving CPR due to asystole the mortality increased by 59% and 11% fewer patients were discharged with GOS 4-5. After in-hospital CPR due to shockable and non-shockable rhythms the mortality increased by 43% and 38% respectively. Regardless of rhythm, 19% fewer patients were discharged with GOS 4–5.

Conclusion:
In contrast to studies by other authors we did not find a benefit of therapeutic hypothermia on the neurological outcome of patients after resuscitation for shockable rhythm. It was confirmed that the neurological outcome of patients after resuscitation for non-shockable rhythm was either unchanged or worse in 2010. This effect may have been influenced by mistakes made when performing therapeutic hypothermia.
