Adhesions, gelatinous ribbons seen in surgical drain tubing. Frequently covers fluid–exuding wounds such as venous ulcers.
Occurs with increasing vascular permeability and fibrinogen leakage into interstitial spaces. Excessive amounts of fibrin that coats tissue surfaces may cause them to adhere.
Surgical drain fluid
Found during the midpoint in healing after sx or tissue injury. Composed of RBCs and serous fluid, which is semiclear pink and may have red streaks.
Skin blisters , pleural effusion
Results from outpouring of fluid. Seen in early stages of inflammation or when injury is mild.
PGs cause vasodilation LTs stimulate chemotaxis.
Produced from arachidonic acid
Stimulate histamine release and chemotaxis.
Anaphylatoxic agents generated from complement pathway activation.
Cause contractions of smooth muscle and vasodilation. Result in stimulation of pain.
Produced from precursor factor kininogen as a result of activation of Hageman factor (XII) of clotting system.
