Examination of the nasal passage should be done with a Thudicum nasal speculum under adequate lighting to identify bleeding points (1)
- if a blood clot is present, advice the patient to blow their nose (with caution) or it can be removed using suction (1)
- topical sprays containing a combination of anesthetics and vasoconstrictors can be used to control bleeding in order to carry out an adequate physical examination (2)
Laboratory studies are indicated in:
- patients with severe hemorrhage - full blood count, coagulation studies, blood typing and screening for possible transfusion
- patients taking warfarin - full blood count, coagulation studies
- patients with systemic conditions - investigations for hepatic or renal dysfunction (2)
