Blood loss estimation in epistaxis scenarios

Abstract

Thirty-two members of staff from the Ear, Nose and Throat Department at Warrington General Hospital were asked to estimate blood loss in commonly encountered epistaxis scenarios. Results showed that once the measured volume was above 100 ml, visual estimation became grossly inaccurate. Comparison of medical and non-medical staff showed under-estimation was more marked in the non-medical group. Comparison of doctors versus nurses showed no difference in estimation, and no difference was found between grades of staff.
