Multicenter Study
The Association between Post-Cardiac Arrest Cerebral Oxygenation and Survival with Favorable Neurological Outcomes: A Multicenter Study.
Cerebral oximetry is a non-invasive system that uses near infrared spectroscopy to measure regional cerebral oxygenation (rSO2) in the frontal lobe of the brain. Post-cardiac arrest rSO2 may be associated with survival and neurological outcomes in out-of-hospital cardiac arrest patients; however, no studies have examined relationships between rSO2 and neurological outcomes following in-hospital cardiac arrest (IHCA). We tested the hypothesis that rSO2 following IHCA is associated with survival and favorable neurological outcomes. ⋯ There may be a significant physiological difference in rSO2 in the first two hours after ROSC in IHCA patients who achieve favorable neurological outcomes, however, this difference may not be clinically significant.

Observational Study
Intra-arrest transoesophageal echocardiographic findings and resuscitation outcomes.
The relationship between echocardiographic findings of intra-arrest TEE and resuscitation outcomes was not clearly identified. We assessed echocardiographic findings observed in intra-arrest TEE and its relationship with resuscitation outcomes. ⋯ Intra-arrest TEE identifies specific findings related to causes of cardiac arrest. Presence of specific findings is associated with poor resuscitation outcomes.

Assessment of brainstem function plays a key role in predicting the neurological outcome after cardiac arrest. However, the relationship of the two quantitative brainstem assessment methods-automated infrared pupillometry (AIP) and auditory brainstem response (ABR)-with neurological prognoses remains unclear. This study compares the prognostic value of AIP and ABR after cardiopulmonary arrest. ⋯ Although AIP and ABR were correlated, the AIP measures were superior in predicting the neurological outcome after cardiac arrest as compared with the ABR measures.
