|
Change from baseline in temperature gradient at 3h post-surgery
Zeitfenster: baseline and 3h post-surgery
|
One temperature probe is attached to the index finger of the lying patients, a second probe at the radial side of the forearm, midway between elbow and the wrist.
Temperature gradient is calculated by subtracting the value obtained at the fingertip from the forearm value and expressed in °C.
