NCT ID: NCT05737147 Completed - Clinical trials for Cardiac Surgical Procedures

Comparison of the Accuracy and Precision of a Zero Heat Flux Thermometer (SpotOn) Versus Pulmonary Artery Temperature.

Start date: September 1, 2018
Phase:
Study type: Observational

In this study, we aim to compare the core temperature measured with two noninvasive ZHF thermometers and a urinary bladder thermometer against a gold standard blood temperature measured in the pulmonary artery in patients undergoing on-pump cardiac surgery. Additionally we intend to compare the reproducibility of the ZHF measurements by using two devices simultaneously in each patient.

NCT ID: NCT04571554 Completed - Clinical trials for Temperature Monitoring

Accuracy of Infrared Thermography for Detecting Febrile Critically Ill Patients

Start date: October 1, 2020
Phase:
Study type: Observational

Accurate determination of critically ill patient of being febrile or not is an essential part of management critically ill patients as it prompt investigating the underlying cause and initiating therapeutic action. Pulmonary artery catheter thermistor is considered the gold standard for temperature measurement . Central non-vascular thermometer such as esophageal, bladder and rectal thermometer showed excellent correlation and agreement with pulmonary artery catheter thermistor and has been accepted as alternative methods for core body temperature assessment. However, those methods are invasive and cannot be tolerated in conscious patients. Peripheral thermometer such as oral, axillary and tympanic membrane thermometer are either impractical in unconscious patient and/or carry the risk of trauma and infection. Infrared thermography (IRT) is a non-contact and non-invasive imaging approach that enable real-time estimation of body temperature by detecting infrared emission. IRT had been used for screening for mass detection of febrile patients at airport at times of infectious disease outbreak. In adult population, IRT showed good accuracy in detecting febrile patients in emergency department; however, those studies used 37.7⁰ C as the fever threshold and the reference standard was either oral 6 or tympanic membrane thermometer. No studies to the best of our knowledge had evaluated the IRT accuracy in detecting fever in critically ill patients using esophageal thermometer as a reference method.

NCT ID: NCT01795482 Completed - General Anaesthesia Clinical Trials

Preoperative Patient Warming for Prevention of Perioperative Hypothermia in Major Abdominal Surgery

THER-6
Start date: January 2013
Phase: N/A
Study type: Interventional

The study should evaluate how long patients undergoing major abdominal surgery under combined general/epidural anaesthesia have to be actively warmed preoperatively to prevent perioperative hypothermia and postoperative shivering. 99 patients will receive forced-air skin-surface warming for different duration. Body temperature will be measured at the tympanic membrane. The investigators hypothesize that active warming before starting the epidural anaesthesia will decrease the incidence of perioperative hypothermia.
