Agreement between three noninvasive temperature monitoring devices during spinal anaesthesia for caesarean delivery: a prospective observational study
Authors' conclusion
While monitoring of core temperature during obstetric spinal anaesthesia is clinically important, agreement between monitors was below clinically acceptable limits.
Study context
- Population
- Women undergoing elective and emergency caesarean delivery under spinal anaesthesiaincluded in analysis
- Participants
- 166 women
- Exposure
- Oral thermometer and infrared thermometer vs heat flux core temperature monitor (Dräger T-core©)
- Outcome
- Agreement between devices (Bland-Altman LOA; predetermined clinically relevant LOA ± 0.5 °C)
Methodological detailsmethod-comparison (Bland-Altman), error grid analysis
- Method-comparison (Bland-Altman)
- Error grid analysis
Main finding
As reported in the abstract
Agreement between devices (Bland-Altman LOA)
Limits of agreement (LOA)
1.8 °C
CI 1.7–2.0
Heat flux vs Oral thermometer · bias 0.5 °C
LOA
2.3 °C
CI 2.1–2.4
Heat flux vs Infrared thermometer · bias 0.4 °C
LOA
2.0 °C
CI 1.9–2.2
Infrared thermometer vs Oral thermometer · bias 0.1 °C
Observational data: associations, not effects.
Further findings
Hypothermia (heat flux temperature < 36 °C)
- Incidence of hypothermia
- 67% (95% CI 49 to 78%)
Error grid analysis
- Large amount of clinical disagreement between methods
