A Single-centre Study Comparing a Non-invasive Lactate Sensor to Standard Invasive Measurements in Patients Undergoing Coronary Artery Bypass Surgery.

Sponsor: Queen Mary University of London

Summary

The main goal of this study is to see how well a non-invasive lactate sensor measures lactate levels compared to standard blood tests. This might reduce the need for frequent blood draws during surgery recovery, and also provide a more comfortable experience for patients. This will also give us information regarding the suitability of the lactate sensor for monitoring other patients - for instance people attending the accident and emergency department with chest pain in which lactate levels may help make a quick diagnosis. Patients will be approached for this study if they are undergoing routine coronary artery bypass surgery (CABG) or valve replacement surgery. Participants will wear the non-invasive lactate sensor for up to 14 hours, and the readings will be correlated to lactate levels in blood samples. Once the sensor has been removed and the participant has been discharged from their elective surgery admission, the participant has completed the study. Participation in this study and the data collected from the sensor will help us understand how well it works and how it can be used to improve patient care in the future. In the future, the data from this new device will be used to train computer algorithms to provide quick responses that could help manage a patients condition, improving future medical care.
