🟣Drowning 🟣🍃 Drowning is the most common cause of mechanical asphyxia.
🍃Foam in the nose is a classic sign of drowning.
🍃Fresh water cause:
- hemolysis if RBCs- ⬆️K. -⬇️Na-Alter Electrolyte activate leading to Ventricular fibrillation - ⬆️BV by 50% in 1st minute - Acute cardiac failure may result due to relative anaemia and myocardial hypoxia
🍃Salt water cause:- fluid will be drown from blood to lung lead to pulmonary edema- No hemolysis
🍃Deaths in fresh water take about 4-5 min.
🍃Deaths in seawater take about 8-12 min.
🍃Wet drowning is the common type
🍃External Sure signs of drowning:- Foam froth. - Cadaveric spasm
🍃Washer woman hand takes 24hours contact with water to occur.
🍃Peeling of epidermis: 1-2 weeks after submersion.
🍃cooling under water is twice (8 hours) as rapid as inthe air (16 hours).
🍃 Hypostasis is seen in upper half of body
🍃 Adipocere: starts after 3week & complete after 6 month.
🍃 Floatation occurs after 3-7 days in summer &7-10 days in winter.
🍃 Wrinkling of skin began after 12 hours & complete after 24 hours.
🍃Putrefaction starts immediately after extraction from water.
🍃 Planktons and diatoms:- enter all organs except the spleen which is contracted - enter long bone so can be estimated in BM microscopic examination
💗GR:
🍃Delayed death in drowning.
✨due to bronchopneumonia.
🍃Foam froth formation in drowning.
✨ It is formed due to mixture of air, water and mucus during attempts of forcible respiration during drowning.
🍃Goose skin indrowning.
✨ due to rigor mortis of erector pilae muscles.
🍃Peeling of skin in drowning.
✨ due to putrefactive gases collected under the skin
🍃 spleen is contracted and pale
✨due to stress &subsequent increased production of epinephrine.
🍃Floating is earlier in female body
✨due to fat & light bone
🍃Floating is earlier in children.
✨due to light bones.
