Clinical paperRelationship between blood, nasopharyngeal and urinary bladder temperature during intravascular cooling for therapeutic hypothermia after cardiac arrest☆

Methods
This prospective observational study was performed in 12 patients during therapeutic hypothermia following successful resuscitation from cardiac arrest. The study was approved by the Ethics Committee of the Medical University of Silesia and the need for an informed consent was waived. Study exclusions were age less than 18 years or more than 75 years, initial blood temperature less than 35 °C, and the inability to achieve a blood temperature less than 34 °C after 12 h of cooling. All patients were
Results
Patient demographics are shown in Table 1. Patients were recruited between June 2007 and March 2010. Initially, there were 14 patients recruited, but we excluded two patients due to inability to achieve a blood temperature of less than 34 °C after 12 h of cooling.
The mean time to achieve a temperature of less than 34 °C was 4.2 ± 3.6 h (range 1–13 h). A stable temperature profile during hypothermia (maintenance of a BLT in a range of 32–34 °C during the whole final 12 h of the cooling period) was
Discussion
Body temperature of ICU patients can be monitored with a variety of devices and at a variety of body sites.8, 9, 10, 11 During hypothermia we are mainly interested in a core temperature and therefore a most reliable site for temperature management would be either pulmonary artery or jugular venous bulb.10, 12 In practice, measurements of core temperature are performed also in the oesophagus, nasopharyngeal cavity, urinary bladder, rectum or the external auditory canal near the tympanic membrane.
Conclusion
In 12 post-cardiac arrest patients undergoing intravascular cooling, both nasopharyngeal and urinary bladder temperature measurements were similar to blood temperatures measured using a pulmonary artery catheter.

The rate of rewarming and the time to achieve normothermia were found difference between controlled and uncontrolled rewarming in non-randomized studies [178–180]. Rebound or post-rewarming fever was not always suppressed using controlled rewarming [165,170–172].
