Lidocaine is an antiarrhythmic medication of the class Ib type. [7] This means it works by blocking sodium channels thus decreasing the rate of contractions of the heart. [10] [7] When injected near nerves, the nerves cannot conduct signals to or from the brain. [8] Lidocaine was discovered in 1946 and went on sale in 1948. [11]
Post-mortem phenomena to estimate the time of death. The post-mortem interval ( PMI ) is the time that has elapsed since an individual's death . [ 1 ] When the time of death is not known, the interval may be estimated, and so an approximate time of death established.
Body size is an important factor that will also influence the rate of decomposition. [22] A larger body mass and more fat will decompose more rapidly. [22] This is because after death, fats will liquify, accounting for a large portion of decomposition. [22] People with a lower fat percentage will decompose more slowly. [22]
Livor mortis (from Latin līvor 'bluish color, bruise' and mortis 'of death'), postmortem lividity (from Latin post mortem 'after death' and lividitas 'black and blueness'), hypostasis (from Greek ὑπό (hypo) 'under, beneath' and στάσις (stasis) 'a standing') [1] [2] or suggillation, is the second stage of death and one of the signs of ...
Cadaveric spasm is seen in cases of drowning victims when grass, weeds, roots or other materials are clutched, and provides evidence of life at the time of entry into the water. Cadaveric spasm often crystallizes the last activity one did before death and is therefore significant in forensic investigations, e.g. holding onto a knife tightly. [4]
Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...
The ratio of potassium to sodium decreases linearly with time. The reason that the potassium levels rise after death is because of a leak in the cell membrane that allows the concentration to reach equilibrium with the potassium levels in the blood plasma. This method is not exact, but a good estimate for the time since death can be obtained. [2]
The approximate time it takes putrefaction to occur is dependent on various factors. Internal factors that affect the rate of putrefaction include the age at which death has occurred, the overall structure and condition of the body, the cause of death, and external injuries arising before or after death.
