TMCx: “A New Non-invasive Continuous Way to Monitor Core Temperature”
A wearable thermometer (iThermonitor) with FDA 510(k) clearance, developed by a TMCx team—Raiing Medical—has enabled core temperature monitoring for surgery patients in a new non-invasive way in operating rooms. The findings appear in a new study published in the Anesthesia & Analgesia.
More than core body temperature: “The role of wearable thermometer during perioperative period is more than core body temperature monitoring. The clinical validation shows the capacity of iThermonitor as a connected health device to establish the baseline, track the vital signs and support the clinical decisions even after the patients are discharged,” says the studys lead author Lijian Pei, MD, who is the Vice Chief Physician of Anesthesiology Department at Peking Union Medical College Hospital and the secretary of Anesthesia Quality Improvement Committee, Chinese Society of Anesthesiology.
There are 80 million surgery patients on annual bases in United States, whose temperatures need to be maintained within normal limits perioperatively to avoid complications including surgical bleeding, wound infection, slow post-anesthetic recovery, and prolonged hospitalization. “Optimal patient care thus requires accurate temperature measurements throughout the perioperative period. However, the most accurate sites for measurement of core temperature are also the most invasive. There is thus a role for noninvasive methods.” says the studys senior author Daniel I. Sessler, MD, who is the Michael Cudahy Professor and Chair at Cleveland Clinics Department of Outcomes Research. “Axillary temperature, as recorded by the iThermonitor, well represents core temperature in adults having non-cardiac surgery and thus appears suitable for clinical use.”
