Temperature control of patients during surgery

摘要

An infrared radiant heating system for raising or maintaining a uniform core temperature of the body of a patient during surgery, substantially without affecting the temperature of the area surrounding the patient's body, includes an infrared radiant heater located near the patient to provide radiant heat to the entire body or one or more parts of the body of the patient. The system further includes a controller in communication with the heater for controlling the intensity level and distribution of intensity of the radiant heat on the patient's body such that the skin temperature of the patient's body is raised or maintained within a predetermined range resulting in the uniform core body temperature, substantially without affecting the temperature of the area surrounding the patient's body.

1. An infrared radiant heating system for raising or maintaining a uniform core temperature of a body of a patient during surgery, comprising:
infrared radiant heaters which in use are located near the patient to provide radiant heat to the body or one or more parts of the body of the patient, wherein the infrared radiant heaters include a first set of heaters attached to electrodes woven throughout clothing worn by the patient during surgery and a second set of heaters incorporated into an illumination system of an operating room where the surgery is to be conducted; temperature sensors attached to further electrodes woven throughout the clothing and configured to sense the skin temperature at a plurality of positions of the patient's body; a controller in communication with the infrared radiant heaters and the temperature sensors, wherein the controller is configured to control an intensity level and a distribution of intensity of the radiant heat on the patient's body from the first set of heaters and from the second set of heaters such that in use a skin temperature of the patient's body is raised or maintained within a predetermined range as sensed by the temperature sensors; and a detector configured to detect a position of the patient and subjects near the patient, wherein the controller is further configured to adjust the intensity level and the distribution of intensity of the radiant heat from the second set of heaters to avoid heating the subjects detected by the detector.
