In the acute phase of tonsillitis, it is important to adhere to the treatment principle of anti-infective treatment as the mainstay and supportive treatment as a supplement. Drug therapy: Anti-infection therapy mainly targets the pathogenic bacteria to select effective antimicrobials. Penicillin is effective against the more common streptococcal infections and can be the drug of choice. However, in recent years, many bacteria have mutated and developed drug-resistant bacteria, and common penicillin may be ineffective, when more potent antimicrobials must be used to control inflammation. Very serious infections sometimes require hospitalization. The course of antimicrobial agents usually takes about 7 days. Supportive treatment: Encourage your baby to drink small amounts of water several times, eat a light and vitamin-rich diet, and eat more seasonal fruits such as watermelon and duck pears. For babies with poor appetite, little food and high fever, prevent dehydration, infuse fluids as appropriate and supplement vitamin C. If the body temperature exceeds 39℃, give the baby the right amount of antipyretic medicine.
