Assisting Role of Pulmonary Hypostasis Phenomenon in Diagnosis of Drowning

Fa Yi Xue Za Zhi. 2022 Feb 25;38(1):71-76. doi: 10.12116/j.issn.1004-5619.2021.410920.

ABSTRACT

OBJECTIVES: To study the phenomenon of pulmonary hypostasis in corpses of various causes of death, and to explore the potential value of this phenomenon in assisting forensic pathological diagnosis of drowning.

METHODS: A total of 235 cases with clear cause of death through systematic autopsy were collected from January 2011 to June 2021 in Guangzhou. According to the location of body discovery, the cases were divided into the water body group (97 cases) and the nonwater body group (138 cases), and the water body group was further divided into the water drowning group (90 cases) and the water nondrowning group (7 cases). Non-water body group was further divided into the nonwater drowning group (1 case) and the nonwater nondrowning group (137 cases). Three senior forensic pathologists independently reviewed autopsy photos to determine whether there was hypostasis in the lungs. The detection rate of pulmonary hypostasis was calculated.

RESULTS: The detection rate of pulmonary hypostasis in the water drowning group (90 cases) was 0, and the negative rate was 100%. The detection rate of pulmonary hypostasis in the water nondrowning group (7 cases) was 100% and the negative rate was 0. The detection rate of pulmonary hypostasis in the water body group and in the nonwater body group (after excluding 2 cases, 136 cases were calculated) was 7.22% and 87.50%, respectively. There were statistically significant differences in the detection rate of pulmonary hypostasis between water body group and nonwater body group, and between water drowning group and water nondrowning group (P<0.05).

CONCLUSIONS: The disappearance of pulmonary hypostasis can be used as a specific cadaveric sign to assist in the forensic pathological diagnosis of drowning.
