Temperature effect on coagulation function in mild hypothermic patients undergoing thoracic surgeries: thromboelastography (TEG) versus standard tests
Authors' conclusion
Mild hypothermia significantly impaired coagulation function in patients receiving thoracic surgeries, which could be detected by TEGs other than the standard coagulation tests.
Study context
- Population
- Patients undergoing thoracic surgeries
- Participants
- 64 patients
- Comparison
- Active vs passive warming during thoracic surgery; TEG vs standard coagulation tests
- Outcome
- Coagulation function by TEG parameters and standard coagulation tests
Main finding
As reported in the abstract
TEG parameters (mild hypothermia vs normothermia)
- MA decreased with mild hypothermia: 59.4 ± 4.5 mm vs 64.2 ± 5.7 mm
- p = 0.04
- α angle decreased with mild hypothermia: 70.4 ± 5.2° vs 74.9 ± 4.4°
- p = 0.05
- ACT prolonged with mild hypothermia: 122.2 ± 19.3 s vs 117.3 ± 15.2 s
- p = 0.01
- K time prolonged with mild hypothermia: 1.9 ± 1.0 s vs 1.3 ± 0.4 min
- p = 0.02
Further findings
TEG at actual core body temperature (passive warming samples)
- More impaired coagulation than TEG incubated at 37 °C
Postoperative shivering and waking time
- Significantly increased in mild hypothermic patients
