There are oral, anal and axillary methods of temperature detection, of which the oral method is more accurate. According to the oral temperature, fever is categorized into low fever (37.3-38 ℃), moderate fever (38.1-39 ℃), high fever (39.1-41 ℃), and ultra-high fever (41 ℃ or more). 39 degrees or more is considered a high fever.
Fever occurs when there is an imbalance between the body’s heat production and heat dissipation due to infections, allergies, craniocerebral injuries, or neoplastic diseases.
Patients with high fever may experience chills, chills, fatigue, muscle aches, pale skin and other symptoms, and the cause of high fever should be found in a timely manner to timely and targeted treatment, otherwise persistent high fever will cause dehydration, convulsions, respiratory failure, circulatory failure and other complications seriously threaten the patient’s life.
Therefore, if there is a rise in body temperature, should go to the hospital in time to improve the examination, clear cause and then give targeted treatment.
