A cytologic study of the sediments in pericardial fluid as it relates to a diagnosis of the mechanism of death.
We have studied the sediments obtained from the pericardial fluids of 70 cadavers subject to different causes of death. The fluids were taken in the course of corresponding legal autopsies. The samples were organized according to the cause of death and cellular predominance, in the following groups, respectively: hanging, multiple trauma, craniocerebral trauma, other violent deaths, myocardial infarction, pulmonary embolism, and other natural deaths. According to cell type followed these categories: Group 1 (isolated mesothelial cells), group 2 (isolated and plated mesothelial cells), group 3 (inflammatory cells and mesothelial cells, isolated and plated), and group 4 (inflammatory cells and mesothelial cells). The statistical analysis was attained through Pearson's coefficient. We have found a significant statistical relation (P less than or equal to 0.05) between the presence or lack of inflammatory cells and the mechanism of death. In those cases with a short survival period and without cardiac affectation, the presence of inflammatory cells was practically null. Furthermore, differences in the cross-sections of inflammatory cells reflected the duration of the death process, with elements characteristic of acute inflammation revealing acute cardiac process.
