چکیده انگلیسی
A fatal case of butyrfentanyl poisoning was investigated at the Zurich Institute of Forensic Medicine. At admission at the institute approx. 9Â h after death (first time point, t1), femoral and heart blood (right ventricle) was collected, as well as samples from the lung, liver, kidney, spleen, muscle and adipose tissue using computed tomography (CT)-guided biopsy sampling. At autopsy (t2), samples from the same body regions were collected manually. Additionally, urine, heart blood (left ventricle), gastric content, brain samples and hair were collected. Butyrfentanyl concentrations and relative concentrations of the metabolites carboxy-, hydroxy-, nor-, and desbutyrfentanyl were determined by LCâ¿¿MS/MS and LC-QTOF. At t1, butyrfentanyl concentrations were 66Â ng/mL in femoral blood, 39Â ng/mL in heart blood, 110Â ng/g in muscle, 57Â ng/g in liver, 160Â ng/g in kidney, 3100Â ng/g in lung, 590Â ng/g in spleen and 550Â ng/g in adipose tissue. At t2, butyrfentanyl concentration in urine was 1100Â ng/mL, in gastric content 2000Â ng/mL, in hair 11,000Â pg/mg and brain concentrations ranged between 200â¿¿340Â ng/g. Carboxy- and hydroxybutyrfentanyl were identified as most abundant metabolites. Comparison of t1 and t2 showed a concentration increase of butyrfentanyl in femoral blood of 120%, in heart blood of 55% and a decrease in lung of 30% within 19Â h. No clear concentration changes could be observed in the other matrices. Postmortem concentration changes were also observed for the metabolites. In conclusion, butyrfentanyl seems to be prone to postmortem redistribution processes and concentrations in forensic death cases should be interpreted with caution.
