[Simulation in the elective subject forensic medicine in the third section of the medical examination]. / Simulation im Wahlfach Rechtsmedizin im Dritten Abschnitt der Ärztlichen Prüfung.

During the COVID-19 pandemic the third section of the medical examination could be performed on simulation patients and simulators. Their use is also beneficial in forensic medicine, as a higher level of standardization and comparability of examination performance is achieved, and the use of real corpses is often not justifiable for medicolegal reasons. This case reports on the advantages and disadvantages of a simulation in the state examination in which a death certificate was to be completely filled out on the basis of an external postmortem examination on the simulator and an external anamnesis.

Depth of sedation during drug induced sedation endoscopy monitored by BiSpectral Index® and Cerebral State Index®.

PURPOSE: Drug induced sedation endoscopy (DISE) is performed to investigate patterns and sites of obstruction in patients with sleep-disordered breathing (SDB). During DISE the patients are sedated to obtain a muscular relaxation of the upper airway which mimics the relaxation during natural sleep. Different sleep stages are intended to be simulated by drug induced sedation, and it is helpful to measure the depth of sedation. The BiSpectral Index® (BIS) is often used for this procedure. Besides the BIS, other means of sedation depth monitoring exist in anaesthesiology but have not yet been investigated with respect to DISE. Monitoring of the Cerebral State Index® (CSI) is one of these methods. The aim of the study was to compare the BIS and CSI for sedation depth monitoring during DISE. METHODS: Sixty patients underwent DISE monitored by the BIS and CSI in parallel. The BIS and CSI values were compared using the Bland-Altman analysis. RESULTS: The BIS and CSI values differed during the course of sedation during DISE by a mean of - 6.07. At light sedation (BIS 60-80), lower values by 10 scale points of CSI compared with BIS were detectable. At deeper sedation levels (BIS 40-50), the CSI turned to present equal and even higher values compared with the BIS. CONCLUSION: Sedation depth measurement during DISE can be performed by the BIS or CSI, but the differences should be interpreted carefully as comparable data for sleep stages in natural sleep are available only for BIS.
