3. Burtonian line (Lead line)

Features of antemortem blisters:

• surrounded by an area of hyperemeia
• floor is reddened with swelling of papillae

Postmortem blisters (blisters of putrefaction) are formed 18-24 hours after death due to putrefaction and production of gases which force blood, air to liquid fat into the superfical layers of skin forming blisters. They are found first in the lower surface trunk and thighs where there is more fluid collection due to hypostatic edema.

Features of postmortem blisters:

• no surrounding hyperemeia
• floor is not reddened

• person can be thrown away due to the force of the blast, causing blunt force trauma
• shockwave passing through the body mainly injures non homogenous tissues like lung, whereas homogenous tissues such as liver and muscle are spared

Blast lung: Injury to the lung produced as a result of  the shockwave passing through the body

• subpleural patchy hemorrhages
• rupture of alveolar septa
• intrapulmonary hemorrhage
• desquamation of alveolar and bronchial epithelium
• pulmonary edema
• bronchopneumonia

Other injuries

• subperitoneal hemorrhages
• lacerations of viscera
• rupture of stomach, intestine
• intracranial hemorrhage
• brain contusion
• injury to heart, aorta
• pneumothorax
• air embolism – can be cause of death
