Q: What is the most recommended way to measure core body temperature during therapeutic hypothermia (TH)?


Answer: Esophageal temperature measurement

As

• bladder temperature depends on urine output
• rectal measurement lags behind
• axillary and tympanic measurements are out of body and misleading

esophageal temperature measurement is considered the most accurate method to follow core temperature during whole process of therapeutic hypothermia (TH).
