SURE SIGNS OF DEATHa. Bruised corpse (livor mortis)After
clinical death, then erythrocytes will occupy the bottom due to gravity
(gravity), filling the veins and venules, forming patches of red color
purple (livide) at the bottom of the body, except at the base of the
body is depressed hard.Dara remain liquid because of fibrinolysin activity originating from the vascular endothelium. Bruised
bodies usually begin to appear 20-30 hours post-death, the longer the
intensity increases and becomes a complete and settle after 8-12 hours. Before
this time, bruised bodies are still missing (blanch on pressure and can
move if the body position changed. Memucatnya bruising will be faster
and more complete when the emphasis or change of position was made in
the first 6 hours after clinical death. But even after 24 hours, blood still
enough water so that the amount of blood can still flow and form a
swollen corpse in place a new low. Sometimes - sometimes found
blue-black patches of hemorrhage due to rupture of blood vessels.
settlement body bruises caused by the accumulation of cells - blood
cells in appreciable amounts, so difficult to move again. In addition muscle rigidity - ototdinding blood vessels involved are difficult to transfer.Black
body can be used for a sure sign of death, cause of death estimates,
such as bright red bruises on CO poisoning or CN, the color brown in
aniline poisoning, nitrite, nitrate, knowing changes in body position
are performed after the bruised bodies of the living; and memeperkirakan
cause of death.When
the corpse lying bruised bodies that have arisen do not settle into a
position change of face down, then after a while will form a new body
bruised chest and stomach area.Bruised
corpse that has not been settled or are still missing in the
suppression, suggesting the death of less than 8-12 hours before the
examination. Given
the bruised corpse found in the blood vessels, then the state is used
to distinguish the infiltration of blood due to trauma (extravasation). When
the area was carried out slices and then doused with water, then blood
red color will disappear or fade to black bodies, whereas the
infiltration of blood does not disappear.
b. Rigid bodies (rigor mortis)Muscle tone after death is still maintained because the level of cellular metabolism is still running reserves of muscle glycogen breakdown to produce energy. This energy is used to convert ADP to ATP. As long as there is ATP actin and myosin fibers remain flexible. When the reserves in the muscles up, then the energy is not formed yet, actin and myosin muscle becomes stiff and lumpy.The level of rigid bodies (rigor mortis) was assessed by memfleksikan arms and legs to test prisoners. Rigid body started to think - about 2 hours after clinical death, starting from the outside of the body (muscles - small muscles) towards the (centripetal). The old theory of rigid body states that are spread kranio caudal. After 12 hours of clinical death rigid bodies to be equipped, maintained diving 12 hours and then disappeared in the same order. Rigid body is generally not accompanied by shortening of the muscle fibers, but if prior to the rigid body, the muscles are in a stretched position, the rigid bodies when formed will occur muscle shortening.Factors - factors that accelerate the rigid body is a physical activity before death, the body temperature is high, thin body shape with the small muscles and high ambient temperatures.Rigid body can be used to show definite signs of death and estimated time of death. There is some stiffness in the body that resembles a rigid body;• Cadaveric spasm (Instantaneous rigor)Is a form of muscle stiffness that occurs at death and settled. Cadaveric spasm is really a rigid body that arises with a very strong itensitas no relaxation was preceded by a primer. The cause is the result of endless reserves of glycogen and ATP that is local at the time of clinical death due to severe emotional exhaustion or shortly before death. Cadaveric spasm is rare, but often occurs in times of war.Mediko legal interest is to show the attitude of the period of his life, for example, the hand that clutched banda he achieved in the case of death due to drowning, which held a weapon in the hands of a suicide.
• Heat StiffeningIe muscle rigidity caused by the heat coagulation of muscle proteins. Muscles - Muscle pink, stiff but brittle (easily torn). This situation can be found on the victim on fire meti. In the heat stiffening fibers - muscle fibers shorten, causing flexion of the neck, elbows, thighs, knees, forming this attitude does not give specific meaning to the attitude of the lifetime, intravitalitas, cause or manner of death.• Cold StiffeningNamely rigidity of the body due to a cold environment, resulting in freezing of body fluids, including the joint fluid, compression of subcutaneous fat and muscle tissue, joints bent so that when you hear the sound of ice breakup in the joint cavity.
