Children with fever in poor gastrointestinal condition need to choose the appropriate treatment according to their body temperature. If the body temperature is below 38.5℃, it is recommended to take physical cooling to reduce the fever. If the body temperature exceeds 38.5℃, you need to go to the hospital in time, follow the medical advice to give antipyretic and analgesic drugs for treatment, and actively look for the cause of the fever, and then treat the cause after clarifying the cause. If the body temperature does not exceed 38.5℃, you can choose physical cooling. While cooling, pay attention to let the child drink more warm water, measure the body temperature regularly and observe the change of the child’s body temperature. You can put antipyretic patches on the child’s forehead or both sides of the neck to cool down. You can also use warm water to wipe the child’s forehead, both sides of the neck, the armpits, the root of the thighs, the popliteal fossa, the elbow fossa and other places where the aorta travels. However, do not mix white wine or alcohol into warm water to avoid adverse reactions due to absorption of alcohol through the skin. In most cases, after physical cooling, the child’s body temperature can gradually drop until it returns to normal. If physical cooling is ineffective and the child’s temperature continues to rise, or if the temperature exceeds 38.5°C, oral antipyretic medication should be administered promptly. For children 2-6 months of age, acetaminophen-based antipyretics may be used under medical supervision. For children over 6 months of age, ibuprofen may be used. Along with symptomatic fever-reducing treatment, it is important to keep the child hydrated. For fever caused by food accumulation and indigestion, timely hydration is more important. Because children’s bodies sweat during fever, which can lead to water loss and reduced urine output, which may affect the discharge of toxins from the body, drinking more water can help reduce fever and promote the timely discharge of toxins from the body. In addition to drinking water, you can also give your child some vitamin-rich juice or rice soup. Other treatments include giving the child plenty of rest, adjusting the room temperature according to the child’s body temperature, and paying attention to timely ventilation. For fever caused by indigestion, also pay attention to adjusting the diet structure, mainly a light diet, do not eat greasy, cold, stimulating food. When the child’s body recovers, then gradually return to a normal diet.
