Abstract
OBJECTIVES: To establish whether, for the patient presenting with epistaxis, there is a relationship between clinical outcome and serum urea levels measured on initial attendance at the accident and emergency (A&E) department.
METHODOLOGY: Records were reviewed from all patients attending a single teaching hospital A&E department between 1st January 2010 and 11st February 2011 with a diagnosis of epistaxis. Patients were analysed according to their admission serum urea and creatinine levels and then grouped according to clinical outcome.
RESULTS: We identified 278 patients (145 males, 133 females), 82 of which required hospital admission. Eleven required blood transfusion, and five required surgical arrest of the haemorrhage. No patients died. Serum urea and creatinine levels were measured in 119/278 patients. The mean serum urea level was significantly higher in patients admitted for further management of epistaxis than in patients who were discharged from the A&E department (9.35 mmol/l vs. 6.74 mmol/l, respectively; p = 0.003). There was no significant difference in mean serum urea levels between patients who were transfused and patients who were not, or between patients who went to the operating theatre and patients who did not.
CONCLUSIONS: Elevated serum urea levels on hospital admission are related to more severe clinical outcome in epistaxis.
