If the fever can be treated with enemas, the drugs used are generally antipyretic drugs, which are less irritating to the gastric mucosa and rarely cause loss of appetite or indigestion, and the effect of reducing fever is very fast and the duration of fever reduction is longer. However, enemas can easily lead to hypothermia syndrome due to the speed of fever reduction, so it is important to monitor the patient’s body temperature, and if there is hypothermia, it is necessary to wear warm clothes or use hot water to soak the hands and feet to promote the recovery of body temperature. In addition, enemas can easily cause damage to the rectum or anus, and once the injury occurs, it is likely to lead to infection, and once infection occurs, it can also aggravate the fever, because the symptoms of infection can aggravate the fever. Infections are often caused by bacteria, which, when growing and multiplying in the body, stimulate the thermoregulatory center, resulting in an increase in body temperature.
