Summary

Evaluate the reliability and validity of temperature measurements using an existing, Health Canada-approved, non-invasive temporal artery thermometer, and comparing results to an established, invasive gold standard (esophageal probe), in order to assess reliability of this non-invasive method to measure core body temperature in the setting of patients undergoing inter-facility patient transport by land, rotor-wing, and fixed-wing transport vehicles.

Detailed description

Interfacility patient transport can put the patient at risk a drop in body temperature. This drop can harmful to patients with particular illnesses (trauma, stroke, post cardiac arrest), and the very young or old. Measuring temperature and preventing temperature drops are challenging in the transport setting. The temporal artery thermometer (TAT) is widely available, easy to use, non-invasive way to measure body temperature. TAT is believed to be a good tool for paramedics to measure body temperature in the transport setting. However, the evidence on reliability and validity of TAT-derived temperature measurements is lacking because the TAT has not been evaluated in the transport setting. The goal of this study is to evaluate the reliability of the TAT device and compare measures of temperature with an established standard in a broad range of patients undergoing interfacility transport by land ambulance, and rotor- and fixed-wing aircraft.

Conditions

• Body Temperature

Interventions

Type	Name	Description
OTHER	Measurement of temperature using non-invasive means	The study intervention will involve paramedics using the TAT device to measure temperature non-invasively,the first measurements made at least 5 minutes after insertion of the temperature probe (control measurement #1), and also prior to departure from the sending facility (control measurement #2). Once the patient is in the transport vehicle and the vehicle in motion for at least 10 minutes, the paramedics will measure the patient's temperature non-invasively using the TAT. If the transport time exceeds 1 hour, additional measurements taken at 1 hour intervals for the duration of transport (up to a total of 8 hours).
