[G. haimorrhagia, fr. haima, blood, + rhēgnymi, to burst forth]
Medical Dictionary for the Health Professions and Nursing © Farlex 2012


An abnormal escape of blood from an artery, a vein, an arteriole, a venule or a capillary network. Haemorrhage may occur into a body cavity or organ, into tissues such as muscles, or externally by way of a wound. Internal haemorrhage often causes a HAEMATOMA. Severe haemorrhage results in dangerous loss of circulating blood volume and there may be insufficient to supply the heart muscle and the brain. This is inevitably fatal unless a rapid transfusion of blood is given. Insufficient circulating fluid causes the syndrome of surgical SHOCK for which fluid replacement is urgently needed. This need not be whole blood; an infusion of salt water (saline) can save life.

an escape of blood from the blood vessels, due to a wound or disease.
Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A. Saunders, J. P. Margham 2005


The escape of blood from any part of the vascular system. Note: also spelt hemorrhage.
blot haemorrhage A form of intraretinal haemorrhage often noted in background (nonproliferative) diabetic retinopathy, branch retinal vein occlusion, carotid occlusive disease and child abuse. The haemorrhage is located within the inner retina and is limited by the orientation of the inner nuclear and plexiform layers. A small blot haemorrhage is often referred to as a 'dot' haemorrhage.
flame haemorrhage  See preretinal haemorrhage.
preretinal haemorrhage Haemorrhage occurring between the retina and the vitreous body. It is usually large and often shaped like a D with the straight edge at the top. Syn. subhyaloid haemorrhage. Others are flame shaped and occur at the level of the nerve fibre layer and tend to parallel the course of the nerve fibres (flame haemorrhage). Retinal haemorrhages are usually round and originate in the deep capillaries of the retina. Retinal and preretinal haemorrhages usually absorb after a period of time (except those that break into the vitreous), but subarachnoid haemorrhage (which is usually due to a rupture of an aneurysm in an artery of the circle of Willis) must be suspected as they often accompany it. See proliferative retinopathy.
subconjunctival haemorrhage A red patch of blood on the conjunctiva of the eye, due to the rupture of a small blood vessel beneath. The condition is nearly always unilateral and the haemorrhage absorbs spontaneously although it frequently alarms the subject. It may be associated with hypertension, especially in people over 50 years of age. See sickle-cell disease.
subarachnoid haemorrhage; subhyaloid haemorrhage See preretinal haemorrhage.

I’m thinking to try acupuncture for back pain I have for many months (long story, so far nothing helped), but I’m afraid it’ll cause bruises and bleeding – last week when the nurse draw blood from my arm she left a green sign that lasted almost a week. Is it dangerous? Can it cause infection?

A. Has blood drawing ever caused an infection? The same way, if the new and sterile needles are used, the risk is very low.

Take care

Q. My husband has a very small mole that was cut.We can not seem to get it to stop bleeding. Any suggestions? tried a shaving pencil, and band-aids of every size. Just will not stop bleeding.
