The World Health Organization refers to newborns with gestational age less than 37 weeks and birth weight less than 2,500 grams as preterm babies. Premature babies have bright red skin, shallow, fast and irregular breathing, poor sucking power, poor thermoregulation and various reflexes, and low arousal. Special attention should be paid to the feeding and care of preterm infants. The whole strategy of feeding and caring for preterm infants 1, feeding 1, reasonable supplementation of micronutrients Premature infants grow and develop much faster than full-term infants, and the demand for vitamins A, C, D and calcium, iron and other minerals is relatively more than that of full-term infants. Premature babies with birth weight of 1000-1500g can reach 7 times their birth weight at the age of one year; preterm babies with birth weight of 1500-2000g can reach 5 and a half times their birth weight at the age of one year, while full-term babies are generally only 3 times their birth weight at the age of one year. Whether the weight growth of preterm infants is reasonable is an important sign of whether the feeding is scientific, generally 25 grams of daily weight growth is more reasonable. In addition, if you do not give preterm infants timely nutrition, prone to anemia and rickets, the body will also be very weak. 2, breastfeeding For premature babies, there is a greater need for breastfeeding, which helps improve the child’s muscle immunity. Because the stomach capacity of premature babies is very small, each feeding should be small and the time interval should be short. If the baby weighs less than 1,500 grams, it should be fed every one hour; for those who weigh 1,500-2,000 grams, it should be fed every two hours; for those who weigh about 2,500 grams, it should be fed every three hours. If the preemie has poor sucking ability, the mother can feed slowly with a dropper or a small spoon. If the mother does not have enough breast milk, she can supplement some special milk powder (Nestle, Wyeth, etc.) suitable for low weight babies with breastfeeding. The first thing you should do is to wash your hands before feeding and diapering your preemie, so that it is hygienic and free of contamination, and your utensils should be disinfected every day. You should also bathe your premature baby every day and change clothes in time. 2, create a suitable neutral environment Because preterm infants can not be stable to maintain normal body temperature, so after birth should pay special attention to keep warm. In home care, the room temperature should be kept at 26-28℃, relative humidity between 55-65% and fresh air. The lighter the baby’s weight, the higher the temperature of the surroundings should be. The mother should take the baby’s body temperature every day and keep it between 36.5-37°C so that the end extremities are warm and light. Objects such as diapers, clothes and quilts used to wrap the body used by preterm infants should be heated before use.
