Tympanic temperature during therapeutic hypothermia

Tympanic temperature measurement is associated with a high correlation to both oesophageal and bladder temperatures during mild therapeutic hypothermia.

• Tympanic temperature showed a bias of 0.021°C compared to bladder temperature and 0.019°C compared to oesophageal temperature.
• The limits of agreement for tympanic versus bladder temperature were ± 0.80°C, and for oesophageal temperature, they were ± 0.61°C.
• A high correlation was found between tympanic and oesophageal temperatures (r = 0.95) and between tympanic and bladder temperatures (r = 0.96).
• These findings suggest that tympanic temperature may accurately reflect core temperatures during mild therapeutic hypothermia after cardiac arrest.
