Critiquing Evidence - Essay Example Cardiac arrest also causes neurological injury through several mechanisms. These mechanisms include reperfusion that leads to reoxygenation injury and perfusion failure which triggers cerebral ischemia. However, hypothermia can reduce the effects of reoxygenation and reperfusion. Hypothermia also decreases the cerebral metabolic rate for oxygen and provides protection against cerebral ischemia. Sometimes, mild induced hypothermia is considered beneficial to the myocardium. A small reduction of temperature affects the micro vascular blood flow in a drastic way. Several animal studies of AMI suggest that myocardial function can be improved through the mild induced hypothermia condition in the absence of cardiac arrest. However, not all the animal studies demonstrate a reduction in the myocardial damage after the induced hypothermia. Â  There are also several feasibility studies which have been performed on several individuals. These patients have undergone a primary PCI after a certai n period, after the induction of hypothermia. These studies also faced certain limitations. Some of the limitations associated with the procedure include the use of less accurate techniques such as the nuclear imaging and measuring equipments. All the studies that have been performed till lately confirm that the effect hypothermia on neurological upshot after cardiac arrest has improved, hence; this has reduced the mortality rate. The authors also talked about some of the predicaments related to the study.
