2.4 Survival study and neurologic outcome assessment
Survival was recorded daily for 7 days after CA/CPR. A previously
reported neurological function scoring system was utilized to assess the
neurologic deficiency at day 3 and day 7 after ROSC in all successfully
resuscitated animals, which was conducted by two investigators who were
masked to animal grouping [29]. The scoring system consisted of five
parameters: consciousness, corneal reflex, respiration, coordination,
and movement/activity. A total score of 10 was considered as normal.
