Key Points for Daily Care and Cognitive Development of Preterm Infants (Public Health Network) Placenta Previa: The placenta normally attaches to the posterior, anterior, or lateral wall of the uterine body. If it attaches to the lower segment of the uterus or covers the internal os of the cervix, positioned below the fetal presenting part, it is termed placenta previa.Placenta previa is one of the primary causes of late-pregnancy bleeding and preterm birth, constituting a severe complication of pregnancy. It is more common in multiparous women, particularly those with multiple pregnancies.Some cases are accompanied by proteinuria or edema, termed gestational hypertension syndrome. Severe cases may present with headaches, blurred vision, and upper abdominal pain. It is one of the causes of preterm birth.Multiple pregnancies carry a higher risk of complications during both gestation and delivery, with elevated rates of preterm birth, perinatal mortality, and neonatal mortality, making them high-risk pregnancies. To improve pregnancy outcomes, early diagnosis is essential, along with enhanced prenatal care and careful management during delivery. Etiology The mechanisms triggering labor onset remain incompletely understood, leaving many aspects of preterm birth causation unexplained.Analysis of clinical cases indicates that the majority of preterm births result from: ① Gestational hypertension syndrome; ② Premature rupture of membranes, placental abruption, or placenta previa; ③ Multiple gestation or polyhydramnios; ④ Chronic diseases such as heart disease, kidney disease, nephritis, liver disease, diabetes, severe pulmonary tuberculosis, endocrine disorders (e.g., habitual preterm labor), or malnutrition;⑤ Anemia and severe hemolytic diseases; ⑥ Acute infectious diseases with high fever; ⑦ Uterine tumors, endometritis, and cervical incompetence; ⑧ Pelvic and spinal deformities; twin pregnancies or fetal malformations; premature rupture of membranes, umbilical cord abnormalities, and polyhydramnios are fetal factors.⑨ Acute or chronic poisoning; ⑩ Severe emotional stress or overexertion; ⑾ Accidental injury or surgery. In a small proportion of cases, no clear cause is identified.
Daily Care Considerations for Preterm Infants
Enhanced Feeding Support. Preterm babies require adequate nutrition to achieve normal growth and development. Breast milk is easily digestible and nutritionally balanced; preterm infants with sucking ability should be breastfed as early as possible.Many mothers of preemies cannot provide the first feed or stay with their babies. In such cases, mothers can express their milk for family members to deliver to healthcare professionals for feeding. If breastfeeding is impossible or insufficient, use specialized preterm infant formula. Feed small amounts frequently, starting with thinner consistency and gradually thickening, adjusting to the baby's schedule.
Ensure proper warmth. Premature infants have an underdeveloped thermoregulatory system, a large body surface area, and minimal subcutaneous fat, making it difficult for them to maintain stable body temperature. They are highly susceptible to temperature fluctuations in response to environmental changes, making appropriate warmth crucial. A moderate ambient temperature helps premature infants maintain an ideal body temperature. The indoor temperature for premature babies should be kept between 24°C and 26°C (75°F and 79°F), with humidity maintained at 70% to 80%.The lower the baby's birth weight, the closer the ambient temperature should be to the baby's body temperature. Mothers should closely monitor the baby, frequently check their temperature, and strive to maintain it between 36°C and 37°C (97°F and 98.6°F). For babies with hypothermia or weighing less than 2 kilograms, they should be placed in an incubator immediately.
Maintain consistent skin-to-skin contact. Research indicates that many premature infants may exhibit restlessness, attention deficits, poor motor coordination, timidity, or irritability as they grow. These children require extra patience, emotional comfort, and psychological guidance from parents.Premature babies did not fully develop in the womb and require additional physical stimulation to promote bodily function development. Massage provides essential intimate contact, helping regulate the nervous, endocrine, and immune systems. It increases vagus nerve tone, boosts gastrin and insulin secretion, reduces anxiety, and enhances sleep duration and milk intake.
Maintain a comfortable, quiet environment.Newborns require substantial sleep for physical development, and this is especially true for premature babies. Creating a quiet, comfortable environment is crucial. Since premature infants have underdeveloped visual and auditory systems, they prefer dim lighting and quiet surroundings. Minimize exposure to loud sounds and bright lights; avoid direct light shining into the baby's eyes to prevent retinal damage.
Key Considerations for Premature Infant Cognitive Development
Medical professionals advise parents of premature infants to begin observing and understanding their child's motor and cognitive development from birth. This enables timely medical intervention should issues arise, minimizing potential harm.
Parents must remember that a premature infant's mental development should be assessed using corrected age (Corrected Age = Birth Age in Months - (40 - Gestational Age at Birth) / 4)For example: A baby born at only 32 weeks gestation who is now 3 months old has a corrected age of 3 - (40 - 32) / 4 = 1 month. At this stage, the child's height, weight, and head circumference can be compared to the growth charts for a 1-month-old full-term infant. Corrected age is used until the child reaches 24 months (2 years).
British physicians believe that supplementing premature infants with salt significantly benefits both physical and cognitive development, with these advantages persisting into the teenage years.
Generally, infants born 8 weeks or more prematurely lose more sodium in their urine compared to full-term babies. Consequently, supplementing premature infants with salt during the first two weeks has become standard hospital practice.They conducted a 13-year follow-up study on two groups of premature infants. Results showed that infants who received salt supplementation after birth scored 13% higher on IQ tests than those who did not receive supplementation.
Additionally, they demonstrated superior performance in memory and language assessments. Physicians noted that these infants received supplemental salt only during the first two weeks of life. Once sodium loss ceased, no further supplementation was administered. However, the sodium intake during this critical period laid a solid foundation for their subsequent physical and cognitive development.
