Other factors governing selection of arteries to be used for injection
- Infant: Descending abdominal aorta, femoral, topically.
- Adult: Varies
Age
Females- if low cut shirt, not the carotid
Sex
May be a problem with raising the femoral.
Fat Distribution
- Arthritis
- Tumors
- Cachexia (wasting syndome)
Disfiguration
Abnormal accumulation of fluids in tissue or body cavities.
Edema
Severe generalized edema.
Anasarca
A.S.C.V.D. - Arteriosclerosis cardio vascular disease
Local Obstruction (congestion)
A physical injury or wound caused by external force or violence.
- Mutilation
- Accident
- Surgery
Trauma
- Autopsy protocol
- Medical Examiner/ coroner
Medico-Legal Requirements
- Hospital
- Medical Examiner
Types of Autopsies
- Needs signed permission.
- Concerned with cause of death.
Hospital Autopsy
- Does not need permission.
- Concerned with manner of death.
- Concerned with cause of death.
Medical Examiner Autopsy
- Medical Doctor
- Investigates death
Medical Examiner
- Makes a report to the Medical Examiner.
- Holds official inquests
Coroner
- Anoxia
- Cancer, etc
Cause of Death
- Natural
- Suicide
- Homicide
- Accidental
Manner of Death
- Shave area- if necessary
- Select instruments and prepare ligature
- Locate place of incision using linear guide
- Make proper incision though skin, superficial fascia and deep fascia.
- Blunt dissection though superficial fascia, fat, and deep fascia.
- Find vessels by use of anatomical guide and relative position of the vein.
- Clean off by blunt dissection and ligate vein loosely.
- Clean off and ligate artery loosely.
- Make an incision in vessels.
Proper technique for Raising Vessels
Preparation room item used with suturing needles to suture cuts and incisions.
Ligature
The separation and pushing aside of the superficial fascia leading to blood vessels and then the deep fascia surrounding blood vessels, utilizing manual techniques or round ended instruments which separate rather than cut the protective tissues.
Blunt dissection
To tie off an artery and vein upon completion of embalming.
Ligate
Lying at right angles to the long axis of the body.
Transverse vessel incision
A vascular incision made on vessels by cutting in an oblique or slanting direction.
Diagonal vessel incision
A vascular incision that is made length-wise on a vessel.
Longitudinal vessel incision
