“…In recent years, several studies on the accuracy of IRT have been published with conflicting results. [14][15][16][17][18][19][20][21][22][23] We therefore evaluated the prototype in a population undergoing rapid changes in core temperature, using a large number FIGURE 1 Bland Altman plot of the paired measurements displayed against the average of the pair when the prototype of the infrared ear thermometer (IRT 4000) was compared to the pulmonary artery (PA) catheter.…”

“…In other studies, pulmonary artery thermometry was preferred as the reference method. [16][17][18][19][20][21][22][23] However, the statistical evaluation recommended by Bland and Altman 11 was not used in all studies. 16,17 This method considers that the result of any comparison of two instruments for clinical measurement can be due to technical errors in the reference method as well as in the new method to be tested.…”

Purpose:To evaluate the equivalency of the prototype of a new infrared ear thermometer (IRT 4000) in comparison to the temperature measurements of a pulmonary artery catheter (PAC) and a continual contact probe on the tympanic membrane. Methods:After approval by the local Ethics Committee, 26 (six female and 20 male) patients undergoing elective cardiac surgery were included in a single center open trial. During surgery, temperature measurements were recorded with the IRT 4000 in the left ear, and with a tympanic contact probe in the right ear, as well as with a PAC as reference. Measurements with the infrared ear thermometers and continual PAC values were recorded every six minutes. Results:The average temperature measured with the IRT 4000 was 0.08°C above the temperature of the PAC (95% confidence interval from -0.44-0.61°C). Conclusion:Infrared ear thermometers 4000 temperature readings accurately reflect body core temperature and correlate well with the invasive PAC. Infrared ear thermometers may present a clinically useful alternative to the pulmonary artery thermometry for the measurement of core temperature in the perioperative setting or in the intensive care unit. P ERIOPERATIVE hypothermia is associated with numerous complications such as surgical wound infections, 1 increased bleeding and transfusion requirements, 2 morbid cardiac events 3 and increased costs of the perioperative management. 4 Therefore, monitoring of body temperature is regarded as essential during anesthesia. 5 Pulmonary artery thermometry reflects the temperature of the blood which supplies the vital organs and is often regarded as the "gold standard" for the measurement of core body temperature. 6 However, it is generally accepted that none of the current thermometry methods is ideal, and the best anatomical measurement site alternative to the pulmonary artery has yet to be determined. ObjectifTemperature measured on the tympanic membrane correlates well with the temperature of the hypothala-CARDIOTHORACIC ANESTHESIA, RESPIRATION AND AIRWAY

“…Axillary temperatures were corrected upward a single degree Fahrenheit. 10,11 The current analysis was limited to women with singleton, term pregnancies with cephalic presentation and the spontaneous onset of labor (n ¼ 1329). From this group, women were excluded if they were diabetic (n ¼ 33), or if birthweight was missing (n ¼ 4).…”

BACKGROUND:Epidural analgesia is associated with an increased rate of fever in prospective randomized trials. While the evidence suggests that epidural fever is not infectious, epidural analgesia has been associated with increased rates of antibiotic use, the indications that prompt treatment have not been examined. METHODS:We analyzed 1235 nulliparous women with singleton term pregnancies presenting in labor with a temperature of <99.51F. Antibiotic use during labor was categorized by indication. RESULTS:A total of 59.6% of women received epidural analgesia. The rate of antibiotic use was significantly higher in women receiving epidural analgesia (28 vs 10.8%). After adjusting for confounders using logistic regression, epidural analgesia was associated with a relative risk of 2.6 (95% CI 2.0, 3.4) for antibiotic treatment. The majority of the increased risk was due to significantly higher rates of antibiotic treatment for presumed chorioamnionitis (9.0 vs 0.4%) in the epidural analgesia group. CONCLUSION:Epidural-related fever results in excess maternal antibiotic treatment for presumed chorioamnionitis.
