In recent years, the incidence of preterm birth is increasing, and the incidence of preterm birth in China is close to 8%. Now we are going to introduce to you the matters that should be paid attention to after the discharge of preterm infants from hospital feeding, hoping to help the families of preterm infants. The main difference between dairy products is the different energy density, 100ml of formula for preterm infants contains about 80kcal, 100ml of post-discharge formula for preterm infants contains about 73kcal of energy, while 100ml of breast milk or formula for full-term infants is about 67kcal. different preterm infants need different energy density, if the weight at the time of discharge and its correction If the weight at the time of discharge is in accordance with the weight of the corrected gestational age, the baby can be fed with exclusive breast milk or formula for full-term infants; if the weight is lower than the weight corresponding to the corrected gestational age, the baby needs to be fed with formula or breast milk + breast milk additives after discharge; if the weight is significantly lower than the weight of the corrected gestational age, the baby can also be fed with formula for preterm infants for a short time. 2. Feeding time: For full-term infants, you can feed on demand, but preterm infants, especially those born at a particularly small gestational age, still need to be fed regularly after discharge. Usually 1 feeding in about 3 hours. If you sleep for more than 4 hours, you need to wake up to give feedings. The time to feed preterm infants with formula, breast milk + breast milk additive, and formula for preterm infants after discharge is based on their weight gain. If their weight catches up with their growth and they have reached the weight corresponding to the corrected gestational age, they can be switched to exclusive breast milk or formula for full-term infants. This needs to be judged according to the growth curve. There is also a more convenient method is to feed to 3 months after birth or weight up to 4kg, but not as accurate as the previous method. The amount of milk fed at each feeding is directly related to the nutrients and energy intake. Premature babies who reach the discharge condition can generally eat more than 40ml of milk each time after discharge, and some preterm babies can grow to 60ml to 70ml each time within a short time after discharge, but the amount of intake often fluctuates each time, as long as the total daily intake meets the requirements. 4. Precautions when feeding and after feeding: Premature babies have poor organismic ability and are easily fatigued when feeding. Sometimes they fall asleep easily after eating a little milk, but wake up again soon and continue to feed, which makes nursing more difficult. It is recommended to stroke the baby’s face and ears with your hands during feeding to give slight stimulation to prevent him/her from falling asleep and allowing him/her to take in the needed amount of milk at once. Due to the immaturity of the gastrointestinal tract in preterm infants, they are prone to reflux and overflow after breastfeeding. You need to pat the back after each feeding. Hold the child upright with the palm of your hand in a hollow shape and pat the back corresponding to the stomach, tapping gently until you burp out. This pats the gas out of the stomach and reduces the chances of spitting up. After the patting is done, let the baby lie on its side so as to avoid suffocation caused by vomiting. It is also best to transform the crib into a head-high footbed to reduce gastroesophageal reflux.
