The incidence of fetal heart rate changes after intrathecal fentanyl labor analgesia.

Unlabelled: We performed a retrospective review to compare the incidence of new fetal heart rate abnormalities after institution of either intrathecal fentanyl or conventional epidural labor analgesia. In chronological order, the first 100 parturients in active labor who had received epidural analgesia and had recorded fetal heart rate (FHR) traces for 30 min before and after injection were identified, as were the first 100 parturients who had received intrathecal fentanyl analgesia. A perinatologist blinded to the anesthetic technique evaluated each recording and identified any changes in the FHR between the before and after tracings.

[Pentachlorophenol concentrations in tissues and body fluids of normal persons (author's transl)].

Pentachlorophenol (PCP) analyses were performed on tissues and body fluids removed at autopsy from 21 human subjects from the geographical area of Northern Bavaria. The measured concentration of PCP in the urine range between 0.26 micrograms/ml and the detection limit (about 0.
