The effect of admission neutrophil/lymphocyte ratio on mortality in patients admitting to Emergency Department with spontaneous subarachnoid haemorrhage

Objective: There are a lot of studies searching parameters and markers which are effective on prognosis and mortality in subarachnoid haemorrhage. But there aren't any studies about the effectiveness of Neutrophil Lenfosit Ratio (NLR) on mortality.

Materials and Methods: In our study, former information of one hundred and thirty one patients who applying for varied complaints to our emergency service between January 2010 and April 2013 and diagnosed subarachnoid haemorrhage was analysed back and worked on study. The patients were categorized into two groups, namely the deceased and surviving groups.

Results: The most frequent designated complaint was headache (51.1%). Anterior comminican artery anevrism was the most seen (28.2%) and the most mortal (38.8%) developed anevrism in subarachnoid haemorrhage. The conditions of patients who were unconscious in the course of applying developed more mortal. NLR was found 7.71 ± 6.59 among survivor patients; 16.23 ± 12.68 among dead patients. Neutrophil lenfosit rate was found considerably high among dead patients compared to survivor patients.

Conclusion: In consequence, compared to other parameters Neutrophil lenfosit rate can be used as a simple, easy, and cheap parameter to guess short term prognosis and mortality. Doing more comprehensive and more studies will guide for the reason of high rates in NLR and the treatment of it.
