2. THANATOLOGY - is the scientific
study of the phenomenon of death &the .
processes relating to death.

3. 1_Somatic or Clinical death
2 _Molecular death

4. Somatic or Clinical Death
Permanent and irreversible damage to;
= Brain
= Heart
= Lungs

5. Molecular Death
 Death of individuals tissues and cells
 Process competes by two to three hours
after somatic death (molecular time)

6. Transplantation of organs like:
 Liver – within 15 minutes
 Kidney 30-40 minutes
 Heart 1 hour

8. Brain death : unaware  bed sores
Brain stem death deep coma
Whole brain death

9. Preconditions Exclusions
Brain stem
reflexes
Apnea EEG
Brain
circulation

10. Brain- stem reflexes
 Pupillary reflext  Optic
 <- Occulomotor
 Vestibulo-reflex occular -> Auditory
 <- Abducent
 Corneal reflex -> Trigeminal
 <- Facial
 Gag reflex -> Glossopharyngeal
 <- Vagus
 Dolls eye reflex - > Auditory
 <- Abducent

12. Sudden Death
Un expected death which caused rapid 2 h
after terminal illness .
