Fiji School of Medicine – Commitment to Excellence… DROWNING  Rapid formation of mucus block - Bronchi.  "foam cone" covering the mouth and nostrils.  "dry drowning" - edema of Larynx - no fluid  Stages in drowning:  Surprise - Inhales water.  Holding breath - while struggling  Pink foam – exhalation of fluid.  Respiratory arrest - Pupils dilate.  Final struggle quick attempts to breath.

Fiji School of Medicine – Commitment to Excellence… SMOTHERING  Obstruction of airway. If soft object e.g. pillow or blanket. No trauma.  Injury on the inner lips.  Cyanosis may or may not.  Petechial hemorrhage on the face, typically around the area of the eyes.

Fiji School of Medicine – Commitment to Excellence… BULLET WOUNDS  Entry and exit wounds  Bullet is spinning as it hits the body the entry area is usually smaller than the exit wound.  Bullet may ricochet inside the tissue & travels a path which is not a straight line.  Powder burns - near range hits.  contusion ring (abrasion collar) around the bullet wound usually indicates the angle and close range.

Other types of slash wounds are called "hesitation marks" commonly found in suicide cases.  Incision wounds: lengths greater than their depth, greater amount of subsurface tissue is exposed in an almost oval fashion.  Puncture wound: Stab or shive wound. distinguishable by its clean-cut edges.

Fiji School of Medicine – Commitment to Excellence… BLUNT trauma:  The blow produces a crushing effect  Resulting in contusions, abrasions, lacerations, fractures, or rupture of vital organs.  Red-blue contusions are always present, but this varies by the weight of the individual (obese people bruise easier than lean people).
