Comparison of a Continuous Noninvasive Temperature to Monitor Core Temperature Measures During Targeted Temperature...

Area of Science:

• Medical Devices
• Physiology
• Clinical Monitoring

Background:

• Targeted temperature management (TTM) traditionally relies on invasive core temperature measurements.
• Current methods include esophageal (Et), bladder (Bt), and rectal (Rt) temperature monitoring.
• Limitations exist in the accuracy and invasiveness of existing core temperature monitoring during TTM.

Purpose of the Study:

• To evaluate the accuracy of a continuous noninvasive temperature monitor.
• To assess its ability to approximate core body temperature during TTM.
• To compare noninvasive monitoring with traditional core temperature methods.

Main Methods:

• A prospective study involving patients undergoing TTM with a gel pad surface TMD.
• Simultaneous recording of core and continuous noninvasive temperature monitoring data for up to 72 hours.
• Bland-Altman analysis to assess agreement between the two temperature measurement methods.

Main Results:

• Twenty subjects (55% women, mean age 57 years) contributed 999 hours of paired temperature data.
• The continuous noninvasive monitor showed good agreement with core temperature measures (mean difference 0.06 ± 0.39°C).
• No proportional bias was detected between the noninvasive monitor and core temperature readings.

Conclusions:

• Continuous noninvasive temperature monitoring is a viable alternative for assessing core temperature during TTM.
• This noninvasive approach offers a potentially more comfortable and less invasive option.
• Further research is recommended to integrate continuous noninvasive temperature monitors into TTM protocols.
