1. Death from Drowning, Death from Drowning, Lightning and Lightning and Electrocution Electrocution Unit-7 Dr. Vivek Kr. Singh Assistant Professor Department of Veterinary Clinical Complex

2. Drowning Drowning prevention of atmospheric air for entering the lungs caused by the submersion of the body in any fluid medium means death from

3. Death from drowning results from complex patho-physiological events that differ according to the composition of liquid in which the animal is submerge

4. Signs of death due drowning A fine white lathery froth is seen at the mouth and nostrils The skin shows a corrugated appearance Early rigor mortis The lungs are distended like baloons Oedematous and spongy lungs White froth in the larynx, trachea and bronchial tubes Presence of water in lungs Large amount of water in stomach containing objects present in water at time of immersion Injuries on the body

5. Mode of Death in case of drowning Asphyxia Shock Fatal injuries

6. Lighting Stroke and Electrocution When animal contact with a flash of lightning, Death is usually immediate and is due to involvement of The central nervous system The central nervous system Paralysis of heart Paralysis of heart Paralysis of respiratory system Paralysis of respiratory system is brought into

7. The cause of death from electric currents is not necessarily the same in all cases Low intensity current causes ventricular fibrilation High intensity current causes paralysis of respiratory centre Lightning is always a DC current and peaks vary from 10,000 to 2,00,000 amperes and voltage upto2,00,00,000 volts The Current of 110 to 220 volts is sufficient to kill an adult cattle

8. Symptoms Varying degrees of shock may occur Animal may fall dead without struggle In less severe becomes unconscious and after a few minutes may recover completely Some animal may show residual nervous symptoms such paraplagia and hyperaesthesia Animals which intermittent shock eat and drink with care cases, the animal as depression, cutaneous have received

9. Singeing and burning marks occur in about 90% cases of lightning, mostly on medial side of limbs Half-chewed food in the mouth is a significant finding in case of a lightning stroke

10. Causes of death Severe Nervous shock Paralysis of respiratory centre Ventricular fibrilation
