Cerebral Desaturation Clinical Trial
Official title:
Observational Study on the Clinical Impact of Systemic and Cerebral Desaturation During Liver Transplantation and Hepatectomy
The purpose of this study is to determine the clinical impact of cerebral and systemic desaturation during liver transplantation and resection on post-operative complications.
This is an observational study. Cerebral and systemic oxymetry (rSO2) using near infrared spectroscopy (NIRS, Invos 5100; Somanet- ics Corporation, Troy, MI) will be performed on all patients with 4 optodes (right and left temporal area, arm and leg). Continuous rSO2 values will be stored on a hard disk with a 15 seconds update within intraoperative period and first 4 hours after the surgery. Desaturation phases (saturation decrease more than 20% of the basal value for more than 15 seconds) will be correlated to operative procedure or events. Postoperative adverse events will be collected. A correlation between desaturation and postoperative adverse events will be done with a multiple linear regression model. ;
