The Effects of Demographic and Clinical Data of Patients on Cerebral Oxygen Monitoring Values

Overview

The aim of this study is to examine the effects of patients' clinical and demographic datas on cerebral oxygen saturation values. Brain oxygenation is measured using near infrared spectroscopy (NIRS). The primary outcome measure of the study is the regional oxygen saturation (rSO2) values measured on the monitor at twelve time points. The other primary outcome measures consist of baseline arterial and venous blood gas analysis and baseline activated clotting time measurements.

This prospective observational study analyzes 80 patients between the ages of 25-80 years who are undergoing elective coronary artery bypass grafting (CABG) surgery. Demographic data of the patients such as age, gender, comorbidities, body mass index are recorded. In addition to standard monitoring, cerebral oximetry monitoring (NIRS) is applied to the patients. Baseline arterial and venous blood gas analysis values, baseline activated clotting time measurements are recorded. Durations of anesthesia, surgery , cardiopulmonary bypass , aortic cross- clamping are recorded. Time points for rSO2 values are baseline, induction, sternotomy, cannulation, pump entry, cross clamp placement, 34º C ,36º C, lowest temperature, cross clamp removal, pump exit, skin closure.
