Central temperature will be monitored with the SpotOnTM3MTM device from entering till leaving the operating room, through a sensor placed in the patient's forehead. Room temperature will be kept at 17 degrees Celsius (ºC). Patients will be warmed with a underbody forced-air blanket (BairHuggerTM3MTM) set at 38ºC and maximal flow, initiated after performing the neuraxial block and stopped right before leaving the operating room.
