Correct Answer � D Explanation |

Ans:D.)Vagal inhibition.
The mode of death shown in the picture above represents drowning in cold water.
TYPES OF DROWNING
Wet Drowning
- In this the water is inhaled into lungs . This is of two types, i.e. Fresh water and Salt water drowning.
- Haemodilatation (Fresh water drowning)
- Haemoconcentration (Salt water drowning)
Dry Drowning
- Water does not enter the lungs, but death results from immediate sustained laryngeal spasm due to inrush of water into the nasopharynx or larynx.
Secondary Drowning or Near Drowning/Postimmersion Syndrome
- Near Drowning is defined as initial survival at least beyond 24 hours of an individual after suffocation due to submersion in fluid. It does not necessarily lead to long-term survival and is associated with secondary complications, which require further medical management.
Immersion Syndrome or Hydrocution
- Hydrocution or immersion syndrome refers to sudden death in water due to vagal inhibition as a result of:
- cold water stimulating the nerve endings of the surface of the body
- horizontal entry into the water with a consequent strike on the epigastrium
- cold water entering eardrums, nasal passage, and the pharynx and larynx which cause mucosal nerve ending stimulation.
