[Effect of the tumescent infiltration solution temperature on body temperature].

OBJECTIVE
To evaluate the effect of tumescent infiltration solution temperature on core body temperature after liposuction.


METHODS
15 healthy female subjects were randomly divided into 2 groups to receive tumescent infiltration solution at 25 degrees C as group A, or at 37 degrees C as group B. All subjects were under epidural anesthesia. Vital signs, including core temperature, heart rate, respiratory rate and blood pressure, were monitored immediately, 1 hour, 2 hours, 3 hours, 4 hours and 8 hours after operation.


RESULTS
The core body temperature immediately, 1 hour, 2 hours and 3 hours after operation were (35.8 +/- 0.5) degrees C, (35.8 +/- 0.5) degrees C, (36.0 +/- 0.5) degrees C, (36.1 +/- 0.5) degrees C in group A, and (36.5 +/- 0.4) degrees C, (36.5 +/- 0.3) degrees C, (36.5 +/- 0.3) degrees C, (36.6 +/- 0.4) degrees C in group B, showing a significant difference between the two groups (P = 0.008, P = 0.008, P = 0.03, P = 0.033, respectively). There was no difference in body temperature 4 hours and 8 hours after operation and in heart rate, respiratory rate and blood pressure between the two groups (P > 0. 05).


CONCLUSIONS
The tumescent infiltration solutions at room temperature (25 degrees C) can decrease the core body temperature and increase surgical risk. It might not be good for rehabilitation. It is recommended to use tumescent infiltration solution at body temperature (37 degrees C) in liposuction.
