Patient's question:
What kinds of diseases can pediatric surgery treat, and which symptoms belong to pediatric internal medicine? What is the normal head circumference for a 4-month-old infant?Doctor's answer:
Hello, according to the question you raised, the head circumference of children aged 4-5 months is generally slightly more than 42-43 centimeters. Both an abnormally large or small head circumference are considered abnormal. Generally, a small head circumference may be due to delayed brain development, while a large head circumference may be caused by diseases such as rickets due to calcium deficiency or hydrocephalus.Hello, after a burn, if blisters form, first apply a 0.1% povidone-iodine solution or 75% alcohol to the surrounding skin. Clean the wound with physiological saline or soap water. Under sterile conditions, drain the fluid from the blisters. Apply tetracycline ointment to the wound.
