Pediatric anesthesia & critical care
What is the minimum time interval for reporting of intraoperative core body temperature measurements in pediatric anesthesia? A secondary analysis
Authors' conclusion
In conclusion, the core body temperature should be reported at intervals of no more than five minutes to ensure the detection of any temperature change in normothermic ranges.
Study context
- Population
- Children under anesthesia who had participated in another clinical study222,366 measurements analysed
- Participants
- 65 participants
- Comparison
- Measurement intervals of 30 s, 1, 2, 5, 10 and 15 min for intraoperative core body temperature
- Primary endpoint
- Probability of failing to detect a temperature change of ≥0.2 °C at any one measurement point (expected probability <5% acceptable)

Primary result
As reported in the abstract
Probability of failing to detect a temperature change of ≥0.2 °C at any one measurement point, by measurement interval (acceptable if <5%)
- 30 s interval
- 0.2% [95%-CI 0.0-0.7]
- 1-minute interval
- 0.5% [95%-CI 0.0-1.2]
- 2-minute interval
- 1.5% [95%-CI 0.2-2.6]
- 5-minute interval
- 4.8% [95%-CI 2.7-6.9]
- 10-minute interval
- 22.4% [95%-CI 18.3-26.4]
- 15-minute interval
- 31.9% [95%-CI 27.3-36.4]
Secondary outcomes
Failing to detect hyperthermia (>38.0 °C)
- Probabilities lower (n = 9)
Failing to detect hypothermia (<36.0 °C)
- Omitted due to low prevalence (n = 1)
