Details and patient eligibility

About

In the course of a scientific accompanying program, the project pursues the goal of gaining further insight into a possible connection between various influencing factors and the development of postoperative delirium. Against this background, in addition to the primary goal of exploring delirium rates, we aim to identify associations between other secondary end goals like the internal circadian time or the heart rate variability and the occurrence of postoperative delirium. For this purpose, patients of the QC-POD (NCT04355195) sample will be studied.

Full description

The project aims to improve the understanding of the internal circadian time (chronotype) and other sleep parameters, as well as further secondary end goals, in relation to the development of postoperative delirium. In the course of this the project would like to investigate the perioperative heart rate variability. Also, the association of perioperative peripheral cholinesterase activity with perioperative heart rate variability and the development of POD will be explored. Additionally, the investigator will analyze the correlation of intraoperative EEG signatures with perioperative heart rate variability, and explore any association of core body temperature and the development of postoperative Delirium.
