Flashcards in Lab Manual 2- Factors for selection of arteries, techniques Deck (43)
- Fat distribution
- Edema, anasarca
- Location obstruction (congestion)
- Medico-legal requirements
- Cause of death
- Manner of death
Other factors governing selection of arteries to be used for injection
- Infant: Descending abdominal aorta, femoral, topically.
- Adult: Varies
Females- if low cut shirt, not the carotid
May be a problem with raising the femoral.
- Cachexia (wasting syndome)
Abnormal accumulation of fluids in tissue or body cavities.
Severe generalized edema.
A.S.C.V.D. - Arteriosclerosis cardio vascular disease
Local Obstruction (congestion)
A physical injury or wound caused by external force or violence.
- Autopsy protocol
- Medical Examiner/ coroner
- Medical Examiner
Types of Autopsies
- Needs signed permission.
- Concerned with cause of death.
- Does not need permission.
- Concerned with manner of death.
- Concerned with cause of death.
Medical Examiner Autopsy
- Medical Doctor
- Investigates death
- Makes a report to the Medical Examiner.
- Holds official inquests
- Cancer, etc
Cause of Death
Manner of Death
1. Shave area- if necessary
2. Select instruments and prepare ligature
3. Locate place of incision using linear guide
4. Make proper incision though skin, superficial fascia and deep fascia.
5. Blunt dissection though superficial fascia, fat, and deep fascia.
6. Find vessels by use of anatomical guide and relative position of the vein.
7. Clean off by blunt dissection and ligate vein loosely.
8. Clean off and ligate artery loosely.
9. Make an incision in vessels.
Proper technique for Raising Vessels
Preparation room item used with suturing needles to suture cuts and incisions.
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.
To tie off an artery and vein upon completion of embalming.
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
A vascular incision created by making a short transverse incision at a right angle to the long axis of the vessel; then with the point of the scissors inserted into the original opening, a second incision is made parallel to the long axis of the vessel.
T-shaped vessel incision
A vascular incision which is made by cutting a small triangular wedge from the wall of a vessel.
Triangular (wedge) vessel incision
- Triangular (wedge) incision
- T-shaped incision
Allows us to better be able to insert the cannula
- Avoid the use of veins which require the abrupt turning of a curve by the drain tube, as the rupturing of the vein may result.
- Be sure the tube is well lubricated to insure easy insertion and prevent the rupture of the vessel wall. Oiling the inside of the drain tube will help prevent blood coagulation within the tube.
- Always use the largest tube the vein will accommodate. This insures the most copious flow of both liquid blood and clots.
Precautions during insertion of the drain tube
The process of converting soluble protein into insoluble protein by heating or contact with a chemical such as an alcohol or an aldehyde. The solidification of a solution into a gelatinous mass. This is a specific form of agglutination.
