I. Fasting time Preoperative fasting is a very painful thing for children, parents are also very distressed, as anesthesiologists we are also very distressed, fasting for such a long time, we can not bear. However, fasting is necessary and is an important part of the preoperative preparation. The purpose of fasting is to keep the stomach empty to prevent vomiting, reflux and aspiration during anesthesia. When this happens, the consequences can be severe and even lead to death!!!! Specifically as follows: age solid food, milk newborn 4h1~6 months 4h6~36 months 6h>36 months 8h Textbooks mention that you can drink some water 3 hours before the operation, but I feel that how much water to drink the exact amount they do not say, so I recommend that you do not let your child drink. rinsing your mouth 3 hours before is OK. If the surgery is delayed, that is, your fasting time is prolonged, the baby can be rehydrated intravenously. Specifically, you can find the ward nurse to reflect, let the nurse to find the doctor to prescribe some sugar water hanging, prevention and treatment of hypoglycemia occurs! The so-called “preoperative injection”, is in the surgery is about to start before the nurse to the child in the hip muscle injection of preoperative drugs, the main role of the child to maintain calm, try to reduce the fear of entering the operating room; reduce oral and respiratory secretions, in order to maintain the child’s breathing fluids. Please hold or support your baby from the time the anesthesiologist picks up your child. Please take the initiative to contact us if you have any problems. Preventing colds
