The child’s tonsil and adenoids surgery is done in the mouth, so the child’s throat pain will be more obvious after the surgery. After six hours, you can let the child hold small ice cubes in the mouth, which can effectively reduce the mucosal edema and relieve the symptoms of sore throat of the child. The next problem is the diet. You must eat room temperature liquid food, not too hot to avoid bleeding in the operation area. Six hours after surgery, you can start drinking milk, and then gradually transition to porridge, chicken cake, noodles, and so on. After eating, you should rinse your mouth to avoid residual food residue, which can easily lead to infection in the surgical area. You can drink more juices to supplement vitamin C, such as orange juice or apple juice. The pseudomembrane in the surgical area will start to fall off in about a week after the operation. During this period, patients need to pay more attention to their diet to avoid bleeding in the surgical area.
