Cognitive and Functional Consequence of Cardiac Arrest
- 676 Downloads
Cardiac arrest is associated with high morbidity and mortality. Better-quality bystander cardiopulmonary resuscitation training, cardiocerebral resuscitation principles, and intensive post-resuscitation hospital care have improved survival. However, cognitive and functional impairment after cardiac arrest remain areas of concern. Research focus has shifted beyond prognostication in the immediate post-arrest period to identification of mechanisms for long-term brain injury and implementation of promising protocols to reduce neuronal injury. These include therapeutic temperature management (TTM), as well as pharmacologic and psychological interventions which also improve overall neurological function. Comprehensive assessment of cognitive function post-arrest is hampered by heterogeneous measures among studies. However, the domains of attention, long-term memory, spatial memory, and executive function appear to be affected. As more patients survive cardiac arrest for longer periods of time, there needs to be a greater focus on interventions that can enhance cognitive and psychosocial function post-arrest.

The effect of mild induced hypothermia on outcomes of patients after cardiac arrest: a systematic review and meta-analysis of randomised controlled trials. Crit Care. 2015;19:417. This is a meta-analysis of six RCT, which showed that mild induced hypothermia (MIH) may not improve mortality after cardiac arrest at hospital discharge, except for those who have a shockable rhythm. MIH improved neurological function at hospital discharge.CrossRefPubMedPubMedCentralGoogle Scholar

Predictors of long-term survival after out-of-hospital cardiac arrest: the impact of activities of daily living and cerebral performance category scores. Resuscitation. 2014;85:1052–8. This study presented prospective data in assessing outcomes for n = 1043 Israeli out-of-hospital cardiac arrest patients. 18.6% of these patients survived. Of these, 1/3 died within 30 months of the arrest. Of those who survived, long-term survival was positively correlated with lower CPC scores and less worsening in activities of daily living from before the arrest to hospital discharge. Most frequently, long-term survival in this cohort was associated with less deterioration in functional status and activities of daily living.CrossRefPubMedGoogle Scholar

This is a randomized controlled trial of 110 comatose patients assigned to receive either hypothermia alone or hypothermia with xenon. The primary outcome was cerebral white matter damage by fractional anisotropy from diffusion tensor MRI between 36 - 52 hours after cardiac arrest. Secondary endpoints were neurologic outcome (mRS) and mortality. Although xenon showed benefit over hypothermia alone in terms of less white matter damage, there was not a statistically significant difference in mRS or mortality at 6 months.CrossRefPubMedGoogle Scholar

A nursing intervention was developed specifically for the purpose of improving neurologic and emotional health related outcomes for cardiac arrest survivors and caregivers (n = 185 and 155 respectively). Improvement in multiple SF-36 domains was assessed at different time points (2 weeks, 3 months, and 12 months). The group that received the intervention experienced improvement in overall emotional state and anxiety after a year. Additionally, at 3 months more people in the intervention group were back at work.CrossRefPubMedGoogle Scholar
