Insights

Exclusively formula-fed newborns consume approximately 115 mL/kg of formula in the first 48 hours of life. This intake is 2-3 times higher than breastfed infants, with minimal weight loss observed.

Area of Science:

  • Neonatal nutrition
  • Pediatric gastroenterology

Background:

  • Understanding infant feeding patterns is crucial for healthy development.
  • Accurate assessment of formula intake is essential for monitoring infant well-being.

Purpose of the Study:

  • To document the formula intake of exclusively formula-fed newborns during the initial 2 days of life.
  • To compare formula intake with typical weight loss in the early neonatal period.

Main Methods:

  • A cohort of 50 healthy newborns (≥37 weeks gestation) was enrolled.
  • Daily formula intake was documented until discharge.
  • Pediatrician's assessment of infant intake was surveyed.

Main Results:

  • 37 of 50 newborns stayed for at least 48 hours.
  • Mean formula intake was 57.2 ± 20.4 mL/kg/d over the first 48 hours.
  • Mean weight loss was 2.7% of birth weight by 45.7 ± 8.8 hours.

Conclusions:

  • Healthy term newborns fed formula ad libitum consume approximately 115 mL/kg in the first 2 days.
  • This intake is significantly higher than that of breastfed infants.
  • Pediatricians tend to underestimate the actual formula intake of newborns.

Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

IV Infusion to Oral Dosing: Conversion Methods

The development of extended-release formulations has facilitated the transition from intravenous to oral medication, offering a more convenient and patient-friendly approach to drug administration. This transition, however, requires careful management to ensure that therapeutic drug levels are maintained, preserving efficacy and avoiding adverse effects. Understanding pharmacokinetic principles and dosage calculations is critical during this process.Pharmacokinetics of the...

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
