Hot compresses are commonly used in clinical practice as a method of local physical therapy. Generally speaking, the contraindications of hot compresses are as follows: First, patients with lower extremity arterial occlusion. Due to the narrowing of the blood vessels of the lower limbs, resulting in local tissue ischemia and hypoxia, at this time to give local hot compresses, it is possible to aggravate the oxygen consumption of the lower limbs, thereby aggravating the manifestation of hypoxia. Second, patients with burns. Scalded patients will have tension blisters in the less severe cases, and there will be coagulative necrosis of local tissues in the severe cases. In this case, if you continue to apply hot compresses, you can only aggravate the local tissue necrosis and play no therapeutic role. Third, comatose patients. Conscious coma patients body’s reaction ability is poor, if given hot compresses, even if localized burns. Patients are often not conscious, in order to avoid accidents, try to prohibit hot compresses.
