Is Esophageal Temperature Better to Estimate Brain Temperature during Target Temperature Management in a Porcine Model of Cardiopulmonary Resuscitation?

Figure 1

Esophageal (), pulmonary artery () and brain temperature () measured in three periods. Normothermia group ((a), (b), and (c)), intravascular cooling group ((d), (e), and (f)), and selective head cooling group ((g), (h), and (i)). Inducing period was defined as time interval from the baseline temperature decrease to 34°C. In our study, time consumed in this period was set to 120 mins. Similarly, maintenance means TTM for 6 hours and rewarming means temperature increased to baseline. While the rewarming rate was controlled at 0.25°C/h, it took another 6 hours to reach the baseline temperature.
