Central Temperature Monitoring by Zero-heath-flux a Non-invasive Technic Compared to Two Invasive Technic During Surgery (TEMP CORE BLOC)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Core temperature monitoring is mandatory during major surgery. The accurate techniques currently used are invasive, such as artery catheter and oesophagal probe. A new non-invasive cutaneous device, 3M SpotOn, using Zero Heath-Flux method, continuously measure core temperature. This prospective study compare the accuracy of Zero-Heath-Flux to oesophagal temperature (30 patients) and to artery catheter (20 patients) in adult patients during surgery.
Condition or disease
Major Surgery in Adult Patients
Device: Monitoring by arterial catheter and Spot-onDevice: Monitoring by oesophagal probe and Spot-on
Every patients undergoing heavy surgery had their central temperature monitoring, through an arterial catheter if the surgery required it (30 patients in this arm), otherwise the investigators used an oesophagus tube (20 patients). We also monitored every 50 patients with a non-invasive method 3M spot on (Zero-heath-flux technic) in order to measure its fiability and validity during the surgery.
