| Popis: | Peripheral blood concentrations are generally preferred for postmortem toxicological interpretation, but some autopsy cases may lack blood for sampling due to decomposition or large traumas etc. In such cases, other tissues or bodily fluids must be sampled; however, limited information exists on postmortem concentrations in matrices other than blood. Pericardial fluid, muscle, and vitreous humor have been suggested as alternatives to blood, but only a few studies have investigated the detection of opioids in these matrices. In this study, we aimed to investigate the detection of methadone, buprenorphine, oxycodone, fentanyl, and tramadol in postmortem samples of pericardial fluid, skeletal muscle, and vitreous humor, in addition to peripheral and cardiac blood; and if drug concentrations in these alternative matrices were comparable to those in peripheral blood, and thereby useful for interpretation. In most of the 54 included cases, only one opioid was detected. Methadone, oxycodone, fentanyl, and tramadol were detected in all of the alternative matrices in almost all cases, while buprenorphine was detected less often. For methadone, the concentrations in the alternative matrices, except for in vitreous humor, were relatively similar to those in peripheral blood. Larger variations in concentrations were found for buprenorphine, oxycodone, and tramadol. Quantitative analyses appeared useful for fentanyl, in all of the alternative matrices, but only four cases were included. Toxicological analyses of opioids in these alternative postmortem matrices can be useful for detection, but interpretation of quantitative results must be performed with caution. |
