Postmortem Stability of Lung Surfactant Phospholipids
The postmortem stability of the main phospholipids of lung surfactant-phosphatidyl choline (PC), phosphatydal ethanolamine (PE), phosphatydal inositol (PI), phosphatydal serine (PS) and sphyngomyelin (S) in three different deaths; one caused by fresh-water drowning, one by salt-water drowning, and one from a sodium-pentobarbital overdose has been studied. The drug overdose was considered the control because there was no surfactant involvement. The results show the stability of these kinds of lipids in the first 24 h, with a progressive decrease from 48 h on until 96 h, with a significant correlation to the time of P < 0.01 in most cases.
