Hypoxic Encephalopathy Clinical Trial
Official title:
Prospective Pilot Trial to Evaluate the NeurOptics Pupillometer and Clinical Examination of the Pupillary Reflex After Cardiac Arrest
The trial will evaluate the use of the "Neurological Pupil index" NPi, measured with the digital pupillometer (NeurOptics) compared to clinical examination for better reliability. The investigators hypothesize that digital evaluation will offer a higher sensitivity/ specificity compared to clinical examination.
Absent pupillary reaction after cardiac arrest might indicate a severe hypoxic encephalopathy. Because the examination of the pupillary reaction is easy it is part of the clinical routine but due to the different medication and the dynamic process of reperfusion injury to the brain a clinical evaluation might be not precise enough. The NPi has been shown to be superior to clinical evaluation in different settings but without regard towards cardiac arrest survivors. The Pupillometer is a hand-held, cordless, and simple to use device which removes subjectivity in the measurement of pupil size and the pupillary light reflex. ;
