Analysis of laboratory parameters in non-traumatic epistaxis

Objective: The present study investigated the relationship between epistaxis and age, sex, hemogram and coagulation parameters and aimed to set a standard in the approach to epistaxis. Materials and Methods: Patients over the age of 18 who presented due to epistaxis between July 1, 2022, and July 1, 2023, were included in this study, and the files of these patients were examined retrospectively. Patients with trauma and chronic hypertension (HT), individuals with diseases that might predispose to bleeding and with a history of bleeding-related drug use such as coumadin derivatives or individuals with malignancy, those who were found to have active infection during the study, patients who were determined to be in the postoperative period, patients whose blood pressure was determined to be above 140/90 mmHg at the time of admission, and those who were found to have blood samples with hemolysis detected in the file records were excluded from the study. Results: The data of a total of 100 patients, including 62 male and 38 female patients, who presented with complaints of epistaxis, were examined. It was found that more patients at older ages presented to emergency departments with complaints of epistaxis and the number of male patients with epistaxis was higher than female patients. It was concluded that headache is the most common early symptom before spontaneous bleeding in nosebleeds, which are more common in older adults, and platelet values, which are negatively correlated with age and positive correlated with activated partial thromboplastin time ( aPTT ) and hemoglobin (HGB ) are an essential marker for nosebleeds. Furthermore, it was concluded that it is meaningless to check coagulation parameters in patients who are not coumadinized, while checking the hemogram remains important.
