Diagnostic Value of Blood Cell Count Diagnosing Sub Arachnoid Hemorrhage (SAH) in Patients presented to Emergency Department

Abstract

Considering the suggestions of previous studies and the lack of information on the diagnostic value of blood count in the diagnosis of subarachnoid hemorrhage. This study aimed to determine the value of diagnostic value of blood count in the diagnosis of subarachnoid hemorrhage in patients referred to the emergency department Following a headache. Materials and Methods: This study is a descriptive study in which all patients with severe headache complaints referred to emergency department of Imam Reza Hospital during three years from 2014 to 2017 and have been evaluated for a definite result of subarachnoid hemorrhage in the study. Patients who left the hospital prior to a definitive diagnosis or left the hospital for continued treatment in the other hospital, or died in an emergency department, or if their document is incomplete or has a known blood disorder, are excluded from the study. The data will be extracted from the medical record and will be filled in the checklist. Results: In this study, 140 patients were enrolled, according to the Kolmogrov-Samyrov statistical method with pv = 0.2, it is obey with normal distribution. In the relationship between data, there is a relation between patient's age and RBC count, patient's hemoglobin and PDW, and the outcome of the patient. There is a significant relationship between the sex, the number of red blood cells and hemoglobin, and the number of platelets in the patient. There is a significant relationship between the number of white blood cells in the patient and the number of platelets and the outcome of the disease and the duration of hospitalization. There is a meaningful relationship between the number of red blood cells and the hemoglobin in the patient. The RDW and PDW of the patient are not related to the outcome or length of hospitalization of the patient.
