  1. Evaluation of hypostasis using a colorimeter measuring system and its application to assessment of the post-mortem interval (time of death).

    Article - En anglais

    Hypostasis was measured in 93 cadavers using a tristimulus colorimeter in order to investigate its relationship with the time of death.

    The intensity (lightness) of the hypostasis in each case was measured over a period of 4 h and the rate of change in lightness derived.

    When examined against the time of death, it was found that there was a good correlation between the two.

    Namely, that the rate of change of lightness (and it can be inferred that this represents displaceability) decreases as the post-mortem period increases.

    The shift in hypostasis was particularly marked in the first 12 h and decreased thereafter.

    However, hypostasis could be useful for time of death estimation for up to 48 h. After this time, the degree of change was small or non-existent and by 72 h hypostasis had become fixed in the majority of cases, within our measuring period of 4 h.
