Haemorrhage
Haemorrhage is defined as the blood coming out of the vessels or rupturing out of the blood vessels.
Types of haemorrhage
(A) Haemorrhage is classified into two types, that is External and Internal .
i.) External haemorrhage: It is the one that is revealed outside or seen externally.
ii) Internally haemorrhage: It is the one that is not seen from outside or it is concealed haemorrhage.
(B) Haemorrhage may be:
i) Arterial haemorrhage: When haemorrhage comes from an artery, it is termed as an arterial haemorrhage. It is bright red in colour.
ii) Venous haemorrhage: It is the one which comes from a vein. It is dark red in colour and it flows out slowly.
iii) Capillary haemorrhage: It is the one in which haemorrhage comes from capillaries. In this case, the blood is bright red and oozes rather then flow out.
(c) According to the time of appearance haemorrhage is of three types:
i) Primary haemorrhage: It is the one which occurs at the time of injury or operation.
ii) Reactionary haemorrhage: It is the one which occurs within 24 hours of injury or operation.
iii) Secondary Haemorrhage: This occurs usually after 7 to 14 days of injury or operation. This type of haemorrhage mainly occurs due to infection.
