Abstract P208: Tracheal Temperature Tube Trial
Introduction Mild therapeutic hypothermia after cardiopulomonary rescuscitation (CPR) is evidenced to improve patients outcome. Pulmonary artery blood temperature is still regarded as a golden standard for core body temperature feedback. However, worldwide esophageal temperature measurement systems are commonly used because of its accuracy and convenient handling.
Methods From 08–11–2008 to 08–04–2009, 24 patients, who have been resuscitated successfully from cardiac arrest, were intended for mild hypothermia therapy according to the guidelines. The patients were intubated with a newly developed endotracheal-test-tube that contains a temperature sensor inside the tube cuff. During the whole process of active cooling, maintainance- and rewarming-phase, the temperature of the endotracheal test-tube was measured minute by minute. Afterwards the data was compared to the temperature assessed by an esophageal temperature probe. In one case the esophageal temperature probe was misplaced in the trachea and in two other cases the patients deceased early after inclusion. The data of these three cases have not been taken into consideration for the overall-result.
Results The mean deviation of the tracheal temperature from esophageal temperature in all 21 patients was measured at −0,218 °C. The overall standard-deviation was satisfactury calculated to 0,145 °C. The median of all patients was measured at −0,200 °C and is presented in figure 1⇓
Conclusion Measurment of tracheal-temperature in the post-rescusitation intensive care medicine is feasible and delivers very accurate and constant results in all phases of the therapeutically induced mild hypothermia.
