Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Neuronal damage caused by neuroinflammation in patients undergoing major surgery is the most determinant factor of postoperative cognitive disfunction (POCD). Neuronal damage can be detected through the measurement of biochemical markers of brain damage. The aim of this study was to evaluate neuronal damage and its association with POCD during liver transplantations. After the approval of the ethics committee and patient consents, preoperative and postoperative cognitive functions of 33 patients undergoing liver transplantation (LTx) were measured using the Mini Mental Test (MMT) whereas simultaneous neuronal damage was evaluated through the measurement of S-100 beta (S100β), Neuron specific enolase (NSE) and Glial fibrillary acidic protein (GFAP) levels. As a result, there was no statistically significant difference between preoperative and postoperative MMTs. However, there was a statistically significant decrease in postoperative GFAP and a statistically significant increase in NSE compared to preoperative values. The decrease in S100β level was statistically insignificant. In conclusion, neuroprotective approaches in the investigator's anesthesia protocol protect patients from brain damage during liver transplantation and prevent the development of POCD, which was indicated by the insignificant change in MMT scores and S100β level and the significant decrease in GFAP. Since the significant increase in NSE levels during liver transplantations was deemed to might have been associated with causes other than neuronal damage, NSE should not be evaluated as a marker of brain damage in these operations.
