POST MORTEM CHANGES WITH TIME INTERVAL
EYE:
Tach Norie Scleroteques (one of the ocular signs of death in which a reddish-brown discoloration is transversely arranged across the sclera) seen
Normal IOT = 25mmHg,
IOT after 30 minutes of death = 03mmHg,
IOT after 02 hours of death = 00 mmHg
ALGOR MORTIS:
Rate of fall of body Temperature:
Summer = 0.5 C / Hour
Winters = 0.7 C / Hour
Time since Death = Normal Body Temperature – Rectal Temperature / Rate of Fall in Body Temperature
Post Mortem Caloricity:Increase in body temperature after death up to 02 hours
e.g. = sunstroke, sepsis, infectious diseases, strychnine poisoning, tetanus etc
Liver Mortis (Post mortem staining):
Visible = 3 – 4 hours
Maximum = 6 – 12 hours
Fixed = 7 – 8 hours
Persists = till decomposition
Does not develop in drowning cases
Carbon Mono-Oxide Poisoning = Pink Cyanide & Flouroacetate = Cherry Red
Refrigeration & Hypothermia = Pink Sodium Chlorate = Brown
Hydrogen Sulfide = Green Aniline = Deep Blue Carbon Dioxide = Blue
Primary Relaxationafter death: lasts for 01 – 02 hours
Rigor Mortis:
Starts after 02 – 04 Hours
Develops after 10 – 12 hours
Remains for = 12 hours
Takes about 12 hours to pass out
Greenish discoloration of body
Summer 12-24 hours
Winters = 36 – 48 hours
Marbling = 36 hours
Maggots = 48 hours
Whole body becomes green= 03 – 04 days
Post mortem Purge = 03 – 04 days
Colliquative Putrefaction= 05 – 10 days (wall of the abdomen softens and bursts open with protrusion of stomach and intestines)
Adipocere formation= 03 days to 03 weeks, No adipocere formation seen if fetus is less than 07 weeks old
