An infant or baby is the very young offspring of human beings. Infant is a formal or specialised synonym for the common term baby. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, an infant who is only hours, days, or up to one month old. In medical contexts, a newborn or neonate is an infant in the first 28 days after birth; the term applies to premature, full term, and postmature infants.
Preterm birth, also known as premature birth, is the birth of a baby at fewer than 37 weeks gestational age, as opposed to full-term delivery at approximately 40 weeks. Extreme preterm is less than 28 weeks, very early preterm birth is between 28 and 32 weeks, early preterm birth occurs between 32 and 34 weeks, late preterm birth is between 34 and 36 weeks' gestation. These babies are also known as premature babies or colloquially preemies or premmies. Symptoms of preterm labor include uterine contractions which occur more often than every ten minutes and/or the leaking of fluid from the vagina before 37 weeks. Premature infants are at greater risk for cerebral palsy, delays in development, hearing problems and problems with their vision. The earlier a baby is born, the greater these risks will be.
Kangaroo mother care (KMC), which involves skin-to-skin contact (SSC), is an intervention to care for premature or low birth weight (LBW) infants. The technique and intervention is the recommended evidence-based care for LBW infants by the World Health Organization (WHO) since 2003.
A neonatal intensive care unit (NICU), also known as an intensive care nursery (ICN), is an intensive care unit (ICU) specializing in the care of ill or premature newborn infants. The NICU is divided into several areas, including a critical care area for babies who require close monitoring and intervention, an intermediate care area for infants who are stable but still require specialized care, and a step down unit where babies who are ready to leave the hospital can receive additional care before being discharged.
A bili light is a light therapy tool to treat newborn jaundice (hyperbilirubinemia). High levels of bilirubin can cause brain damage (kernicterus), leading to cerebral palsy, auditory neuropathy, gaze abnormalities and dental enamel hypoplasia. The therapy uses a blue light (420–470 nm) that converts bilirubin into an (E,Z)-isomer that can be excreted in the urine and feces. Soft goggles are put on the child to reduce eye damage from the high intensity light. The baby is kept naked or only wearing a diaper, and is turned over frequently to expose more of the skin.
Swaddling is an ancient practice of wrapping infants in blankets or similar cloths so that movement of the limbs is tightly restricted. Swaddling bands were often used to further restrict the infant. Swaddling fell out of favour in the 17th century.
Necrotizing enterocolitis (NEC) is a devastating intestinal disease that affects premature or very low birth weight infants. Symptoms may include poor feeding, bloating, decreased activity, blood in the stool, vomiting of bile, multi-organ failure, and even death.
Neonatal jaundice is a yellowish discoloration of the white part of the eyes and skin in a newborn baby due to high bilirubin levels. Other symptoms may include excess sleepiness or poor feeding. Complications may include seizures, cerebral palsy, or kernicterus.
Breastfeeding, variously known as chestfeeding or nursing, is the process where breast milk is fed to a child. Breast milk may be from the breast, or may be pumped and fed to the infant. The World Health Organization (WHO) recommend that breastfeeding begin within the first hour of a baby's birth and continue as the baby wants. Health organizations, including the WHO, recommend breastfeeding exclusively for six months. This means that no other foods or drinks, other than vitamin D, are typically given. The WHO recommends exclusive breastfeeding for the first 6 months of life, followed by continued breastfeeding with appropriate complementary foods for up to 2 years and beyond. Of the 135 million babies born every year, only 42% are breastfed within the first hour of life, only 38% of mothers practice exclusive breastfeeding during the first six months, and 58% of mothers continue breastfeeding up to the age of two years and beyond.
The Baby Friendly Hospital Initiative (BFHI), also known as Baby Friendly Initiative (BFI), is a worldwide programme of the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF), launched in 1992 in India following the adoption of the Innocenti Declaration on breastfeeding promotion in 1990. The initiative is a global effort for improving the role of maternity services to enable mothers to breastfeed babies for the best start in life. It aims at improving the care of pregnant women, mothers and newborns at health facilities that provide maternity services for protecting, promoting and supporting breastfeeding, in accordance with the International Code of Marketing of Breast-milk Substitutes.
Bliss is a UK-based charity for infants. Bliss supports the families of babies in neonatal care and works with health professionals to provide training and improve care for babies. It campaigns for improved hospital resources across England, Scotland, Wales and Northern Ireland, and is actively involved in neonatal research. Its chief executive is Caroline Lee-Davey.
Pain in babies, and whether babies feel pain, has been a large subject of debate within the medical profession for centuries. Prior to the late nineteenth century it was generally considered that babies hurt more easily than adults. It was only in the last quarter of the 20th century that scientific techniques finally established babies definitely do experience pain – probably more than adults – and developed reliable means of assessing and of treating it. As recently as 1999, it was widely believed by medical professionals that babies could not feel pain until they were a year old, but today it is believed newborns and likely even fetuses beyond a certain age can experience pain.
Neonatal withdrawal or neonatal abstinence syndrome (NAS) or neonatal opioid withdrawal syndrome (NOWS) is a withdrawal syndrome of infants, caused by the cessation of the administration of licit or illicit drugs. Tolerance, dependence, and withdrawal may occur as a result of repeated administration of drugs or even after short-term high-dose use—for example, during mechanical ventilation in intensive care units. There are two types of NAS: prenatal and postnatal. Prenatal NAS is caused by discontinuation of drugs taken by the pregnant mother, while postnatal NAS is caused by discontinuation of drugs directly to the infant.
The Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) is a 501(c)(3) nonprofit membership organization. The stated purpose of AWHONN is to promote the health of women and newborns.
Neonatal hypoglycemia, also called low blood sugar in newborn babies, occurs when an infant's blood glucose level is less than what is considered normal. There is inconsistency internationally for diagnostic thresholds. In the US, hypoglycemia is when the blood glucose level is below 30 mg/dL within the first 24 hours of life and below 45 mg/dL after, but international standards differ. Age, birth weight, metabolic needs, and wellness state of the newborn has a substantial impact on their blood glucose level. This is a treatable condition, but its treatment depends on the cause of the hypoglycemia. Though it is treatable, it can be fatal if gone undetected. Hypoglycemia is the most common metabolic problem in newborns.
A neonatal nurse practitioner (NNP) is an advanced practice registered nurse (APRN) with at least 2 years experience as a bedside registered nurse in a Level III NICU, who is prepared to practice across the continuum, providing primary, acute, chronic, and critical care to neonates, infants, and toddlers through age 2. Primarily working in neonatal intensive care unit (NICU) settings, NNPs select and perform clinically indicated advanced diagnostic and therapeutic invasive procedures. In the United States, a board certified neonatal nurse practitioner (NNP-BC) is an APRN who has acquired Graduate education at the master's or doctoral level and has a board certification in neonatology. The National Association of Neonatal Nurse Practitioners (NANNP) is the national association that represents neonatal nurse practitioners in the United States. Certification is governed by the National Certification Corporation for Obstetrics, Gynecologic and Neonatal Nursing Specialties (NCC).
Julius H. Hess was an American physician who is often considered the father of American neonatology. In 1922, he published the first textbook focused on the care of prematurity and birth defects in infants. That same year, Hess and nurse Evelyn Lundeen created the first premature infant station in the United States, recognizing the importance of nursing care and temperature management in the care of preterm babies. Hess also made early contributions to the transport of such infants to specialty centers.
Evelyn Lundeen was an American nurse who headed the first premature nursery in the United States with Dr. Julius Hess. Outside of her work at the nursery, Lundeen traveled to other cities to teach the principles of nursing care for premature infants. With Hess, she also co-authored an early textbook on premature baby care.
Nils Bergman is a Swedish specialist in perinatal neuroscience and a promoter of skin-to-skin contact between a mother and newborn.
Newborn care and safety are activities and precautions recommended for new parents or caregivers. It is an educational goal of many hospitals and birthing centers to promote newborn care and safety as parents take their infant home.
