verb To bleed.

haemorrhageAn 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.
haemorrhagean escape of blood from the blood vessels, due to a wound or disease.
haemorrhageloss of blood from a ruptured blood vessel. In sport, usually the result of trauma. Significant bleeding may result from either an externally obvious injury (e.g. fractured tibia, lacerations) or less obvious internal trauma (e.g. ruptured spleen, lung trauma) and may result in shock. See also shock.
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.
