Edema and haemorrhage were presented. Edema is the abnormal accumulation of fluid in tissues, and can be localized or generalized. It can be transudate or exudate depending on protein content. Haemorrhage is bleeding from blood vessels. Bleeding can be arterial, venous, or capillary. Arterial bleeding is bright red and emitted in a jet; venous bleeding is darker and steady; capillary bleeding is bright red and oozing. Bleeding can be primary, reactionary, or secondary depending on timing relative to injury or surgery. The causes, effects, and types of edema and haemorrhage were described.
5. PITTING AND NON-PITTING EDEMA
PITTING EDEMA NON-PITTING EDEMA
• When a pressure is applied to a small area, the
indentation persists even after the release of the
pressure. It is called as PITTING EDEMA.
• It is also known as Cutaneous edema.
• The type of edema in which the indentation made
by a pressure on the affected area does not persist.
It is called as NON-PITTING EDEMA.
