Flotation tests on the lungs and gastrointestinal tract to investigate aeration are classic procedures to examine the life of a newborn after birth; however, there are arguments about the reliability. The present study investigated serial forensic autopsy cases of newborn infants without marked decomposition (n = 4) with regard to air/gas distribution in the lungs and gastrointestinal tracts by means of postmortem CT (PM-CT) as well as macromorphology and histology, compared with intrauterine and aborted fetuses (n = 3). No gas was detected in the lungs or gastrointestinal tracts in all of three intrauterine fetal deaths. Gas was diffusely detected in the lungs of a newborn fatality attributed to smothering after birth; however, two neonatal fatalities had poor lung gas contents due to marked congestion with edema and diffuse atelectasis. In a case of unsuccessful cardiopulmonary resuscitation following possible birth asphyxia, pulmonary aeration was evidently localized on CT morphology, despite a larger amount of bowel gas, and was also uneven in histology, showing a membranous immunostaining pattern of pulmonary surfactant on the intra-alveolar surfaces of expanded alveoli. The combined use of PM-CT is useful to demonstrate air/gas distributions in the lungs and gastrointestinal tract for interpretation of spontaneous breathing after birth in newborn fatalities.
