59
Q

Because of of ____ ____ investigation, postmortem interval is usually longer. Two solutions are recommended for these conditions:

  1. Restricted cervical injection and drainage method will be utilized (non-autopsied)- good for severe edema, use humectants.
  2. Special purpose high index arterial fluids will be utilized in high concentrations as much as one bottle to a gallon- 30 to 38 index.
A

Medical-legal

60
Q

Most of the bodies that will come under the jurisdiction of the medical examiner will have __ _____. Often, much of the blood discolorations will disappear because of the evisceration process.

A

Full Autopsies

61
Q
  • Hypostasis to livor mortis to hemolysis will occur rapidly- livor mortis to postmortem stain. As little as 6 hours.
  • Fluid distribution and diffusion problems
  • Surface dehydration- most severe in fingertips, lips, eyelids, nose (can part eyelids and mouth)- Tissue builder
  • Distention of viscera during injection causing purge.
  • Capillary rupture throughout vascular system due to ice formation.
A

Major Problems Caused by Refridgeration

62
Q
  • Increased capillary permeability
  • Easy rupture of the capillaries during arterial injection
  • Tissue structure breakdown as a result of the slow, continuous processes of autolysis and bacterial enzymes
  • Increased coagula in the vascular system
  • Gravitation of blood and body liquids into the dependent body tissues, resulting in an increase in mositure in these tissues.
  • Intense livor mortis
  • Rapid hemolysis resulting in postmortem extravascular stain surface tissues, possible skin-slip
  • Decomposition signs (abdominal discoloration, purge and skin slip)
  • Rapid distension of abdominal organs during injection, resulting in stomach and/or lung purge.
  • Increased algor mortis
A

When bodies have been refridgerated for long periods of time and wrapped in plastic or placed in a plastic pouch, the embalmer can expect some of these problems.

63
Q
  • Postmortem edema
  • Blood thickens and agglutinates over time during refridgeration
  • Slow reaction between body proteins and preservative solutions
  • Can solidify subcutaneous fatty tissues so they feel firm to the touch
  • Light pink color
  • Slows but does not stop postmortem chemical and physical change
A

Major Characteristics of Refridgeration

64
Q

Formation of high moisture content in some body tissues because the serum portion of the blood leaves the blood vascular system and gradually makes the way to the surface of the body (imbibition).

A

Postmortem Edema (Refridgeration)

65
Q

Sludge formation/ blood clots.

A

Blood thickens and agglutinates over time during refridgeration

66
Q

Delayed detectable firmness. Cold stiffening is often confused with firming of the tissues.

A

Slow reaction between body proteins and preservative solutions

67
Q

False signal to the embalmer that a reaction has occurred between the preservative solution and the body protein.

A

Refridgeration can solidify subcutaneous fatty tissues so they feel firm to the touch

68
Q

Color will occur confusing the embalmer into thinking the tissue is receiving arterial fluid solution. Results from hemolysis not arterial fluid solution. Always use more than one method to identify signs of distribution and diffusion.

A

Light Pink Color

69
Q

Particularly decomposition and rigor mortis.

A

Refridgeration slows but does not stop postmortem chemical and physical change.

70
Q
  • Allow time for the body to warm
  • Always use cold water to thaw (Never use warm/hot water becuase it causes coagulation and desiccation marks).
  • Restricted cervical method
  • Solution- high index 30 to 38, 16 ounces to a gallon.
  • Add tracer dye and co-injection, do not use preinjection; it will cause “water logging”
  • Hypodermic and surface embalming for areas not receiving arterial fluid solution.
  • Low pressure- low rate of flow- slow gentle rain.
A

Recommended Treatment- Refridgeration

71
Q
  • Head freeze
    • Hot water only works for short distances

73
Q

The femoral artery is most likely to be affected by this. The use of the common carotid artery and right internal jugular vein will be the primary injection site.

A

Arteriosclerosis

74
Q
  1. Type 1
  2. Type 2
  3. Type 3
A

3 Types of Arteriosclerosis

75
Q

The inner wall of the artery is hardened and thickened but the lumen is well defined and large. These vessels can usually be used for arterial injection. This condition is frequently observed in the autopsied body when the common iliac arteries are exposed.

A

Type 1 Arteriosclerosis

76
Q

The lumen is quite reduced in size and pushed to one side of the artery. The lumen can usually be identified and a small arterial tube can be used for injection.

A

Type 2 Arteriosclerosis

77
Q

The artery is completely occluded. If ischemia or gangrene is not present in the area supplied, the collateral circulation may have increased to supply blood to the limb, or there may be minute paths in the occluded artery through which the blood can pass. The formation of these paths or canals is called canalization. These arteries cannot be used for injection.

  • Worst type
A

Type 3 Arteriosclerosis

78
Q

Pre-injection fluid should not be used when it is thought it will be difficult to establish arterial solution distribution. Swelling coud result later when the preservation solution is injected, as the system would be filled with pre-injection fluid. Pre-injection fluid should be used only if circulation is thought to be good; in such cases, it maintains the good distribution and drainage. Many persons who had vascular diseases were given blood thinners and anticoagulants. These bodies generally exhibit good arterial solution distributio and few or not clots in the drainage.

A

Problem of “Water-Logging” as it Relates to the use of Pre-Injection Fluid

Q

Head freeze: Immediate tissue fixation (LAST RESORT)

A

Head: Edema

106
Q

Pressure on the outside of an artery or vein is referred to as this, and may restrict the flow of arterial solution into a body region or may restrict damage through a vein.

A

Extravascular Resistance

107
Q
  • A slightly stonger, well-coordinated arterial solution should be used as distribution may be limited.
  • Multisite injection may be necessary if extravascular resistance is present.
  • Use of higher embalming pressure may promote distribution.
  • Stopping injection and allowing time for drainage may help to prevent blood discolorations.
  • Use of concurrent drainage throughout the entire operation.
  • Massage and manipulate the tissues to promote both fluid distribution and blood drainage.

Q
  • Rigor mortis
  • Ascites
  • Gas in cavities
  • Bandages
  • Contact pressure
  • Tumors
  • Swollen lymph nodes
  • Hydrothroax
  • Visceral weight

Sources of Extravascular Resistance

109
Q

Relieve as much rigor as possible by manipulation prior to arterial injection. This includes the legs and neck.

A

Rigor mortis

110
Q

Relieve the abdominal pressure by draining prior to or during arterial injection. Only in extreme cases.

A

Ascites

111
Q

Puncture the abdomen to relieve gases prior to or during arterial injection. Only in extreme cases.

A

Gas in Cavities

112
Q

Remove tight bandages prior to injection. (Talk about the removal or casts with the family).

A

Bandages

113
Q

Massage these areas. Use positioning blocks to reduce the amount of surface that the body comes into contact with.

A

Contact Pressure

114
Q

Excise, with permission, if absolutely necessary. Sectional injection may be necessary. It does not matter if these are malignant or benign.

A

Tumors

115
Q

Multipoint injection may be necessary.

A

Swollen Lymph Nodes

116
Q

Drainage may be possible prior to injection, but can be difficult.

  • Too risky, the embalming will probably puncture a major artery.
A

Hydrothorax

117
Q

Above and below heart injection and drainage points can be employed.

A

Visceral Weight

118
Q

Always keep the head and neck ____ the chest and abdomen. Otherwise purge and HCHO grey will occur.

A

Above

119
Q
  • Sectional arterial injection
  • Sectional hypodermic injection (used as a supplement to arterial injection)
  • Operative aids (written permission should be obtained).
    • necrotic tissue excision
    • swollen tissue excision
    • New growths excised
    • Surface compresses in case of skin slip, etc.
