A Wearable Biosensor Patch for Non-Invasive Monitoring for Patients Undergoing Abdominal or Chest Surgery

Starting soon · Not applicable

Conditions studied: Hematopoietic and Lymphatic System Neoplasm, Malignant Solid Neoplasm

In brief

This clinical trial tests the feasibility and safety of a wearable biosensor patch for non-invasive monitoring for patients undergoing abdominal or chest surgery. Wearable biosensor patches have been developed by researchers to provide a non-invasive way to monitor substances that are normally checked using blood tests. This may reduce the need for frequent blood draws. The patches use gentle electrical stimulation to produce sweat and tiny built-in sensors to measure substances such as glucose, creatinine, and markers of inflammation, as well as oxygen and carbon dioxide levels. The wearable biosensor patch may be a feasible and safe way to monitor patients undergoing abdominal or chest surgery.
