- Amount of liquid is much less than that of pathological edema.

A

Agonal Exudation

113
Q
  1. Vascular congestion
  2. Increased capillary permeability
  3. Altered osmotic pressure
A

Causes of agonal exudation

114
Q

Decomposition could be accelerated and cavity fluid could be diluted.

A

Danger of agonal exudation

115
Q

The escape of blood serum from an intravascular to an extravascular location, caused by prolonged venous and capillary congestion.

A

Agonal Edema

116
Q

A progressive condition which begins during the preagonal state and continues through the agonal state and postmortem period. Agonal desiccation (same as dehydration) is most pronounced in the lips and membranes of the upper respiratory tract. May times this occurs on the surface as agonal edema occurs in viscera and deeper areas.

A

Agonal Dehydration

117
Q

118
Q
  • Antemortem subcutaneous emphysema

- Gas gangrene

A

Gasses in the tissues

119
Q

The presence of free air or gas in the subcutaneous tissues. The air or gas may originate in the rupture of an airway or alveolus and migrate through the subpleural spaces to the mediastinum and neck.

  • The face, chest and neck may appear swollen
  • No bacteria are involved in causing this condition
  • Most common cause is trauma and/or life support.
A

Antemortem Subcutaneous Emphysema (Aerodermectasis)

120
Q

Causative agent is clostridium perfringens (clostridium welchii). A species of anaerobic gram-positive bacteria. The oval spores of bacteria are found in soil and in the intestinal tracts of humans and animals.
