Children with inflamed and enlarged tonsils can be treated with general therapy, antibiotics such as penicillin, and gargles with gargle solution under the guidance of an ear, nose and throat or pediatrician. Acute tonsillitis is an acute non-specific inflammation of the palatine tonsils, often occurring in spring and fall when the temperature changes. It is often caused by infections such as type B hemolytic streptococcus and non-hemolytic streptococcus. The tonsils are seen to be enlarged and may have yellowish-white pus spots on the surface, often complaining of sore throat and difficulty in swallowing, and may have systemic symptoms such as fever and headache. General treatment includes appropriate isolation, and children who go to school are advised to take leave to rest at home. Drink plenty of fluids, eat a liquid diet, strengthen nutrition, and keep the bowels clear. Application of antibiotics is the main treatment method. Penicillins can be chosen, and the route of administration is selected according to the severity of the disease, such as oral amoxicillin, intramuscular benzylpenicillin, and intravenous penicillin. If there is penicillin allergy, you can choose cephalosporins or macrolides such as azithromycin, etc. Local treatment can use compound borax solution, compound chlorhexidine solution, furacilin solution and other gargles. The above treatments and medications should be carried out under the guidance of a medical professional. If the child has recurrent tonsillitis, tonsillectomy may be considered.
