MDX Viewer Detects Early Warning Signs in Brain Oxygenation During Cardiovascular Surgeries

Patients who undergo open heart surgeries sometimes suffer from post-operative cognitive dysfunction (POCD), which could be caused by lack of oxygen to the brain while under anesthesia. Of the roughly 500,000 patients receiving coronary artery bypass grafting procedures each year, 14–48 percent can be affected with this condition, according to David Platt, PhD, CEO of MDX Life Sciences. If the anesthesiologist notices when a patient’s brain is becoming hypoxic during surgery, steps can be taken to restore oxygen flow. However, detecting that the brain is not receiving enough oxygen is not precise. MDX Life Sciences may have a solution to this in its MDX viewer, which can monitor oxygen levels in the brain by assessing oxygen levels in the tissues of a person’s urethra using an algorithm. “It is a single-use, three-way Foley catheter introduced to the urethra of patient during the perioperative period and in the ICU,” said Platt, in an interview with MD+DI. The device measures four parameters and uses an algorithm to calculate the tissue metabolic score (TMS), which could be used as a new vital sign. An article published in the American Journal of Cardiovascular and Thoracic Surgery, “Perioperative Cardiovascular Evaluation of Patients Oxygen Balance and Tissue Metabolic Score (TMS),” reported that “monitoring the urethral wall oxygen ...
