Hypothesis
The study aimed to assess the clinical reliability and accuracy of the thermometer in the endotracheal tube compared to the core temperature measured using a pulmonary artery catheter.
Conclusion
The tracheal temperature measurement can effectively represent the core temperature of patients undergoing coronary artery bypass graft surgery.
Supporting Evidence
- The mean difference between the tracheal and pulmonary artery temperatures was −0.10°C.
- The concordance correlation coefficient was 0.95, indicating a substantial strength of agreement.
- The 95% limit of agreement ranged from −0.35°C to 0.15°C.
- The majority of temperature differences fell within the limit of agreement.
Takeaway
Doctors can use a thermometer in a breathing tube to check a patient's core temperature instead of using more complicated methods, and it works just as well.
Methodology
The study involved 11 patients undergoing CABG surgery, measuring temperatures at 5-minute intervals for 1 hour before cardiopulmonary bypass.
Limitations
The study was conducted at a single center, and the sample size was relatively small.
Participant Demographics
The participants included 11 patients aged over 18 years, with a mean age of 64 years, predominantly male (9 males, 2 females).
