Neonatal nursing is a sub-specialty of nursing care for newborn infants up to 28 days after birth. The term neonatal comes from neo, "new", and natal, "pertaining to birth or origin". Neonatal nursing requires a high degree of skill, dedication and emotional strength as they care for newborn infants with a range of problems. These problems vary between prematurity, birth defects, infection, cardiac malformations and surgical issues. Neonatal nurses are a vital part of the neonatal care team and are required to know basic newborn resuscitation, be able to control the newborn's temperature and know how to initiate cardiopulmonary and pulse oximetry monitoring. [1] Most neonatal nurses care for infants from the time of birth until they are discharged from the hospital.

Levels of the Neonatal Nursery

There are four different levels of nurseries where a neonatal nurse might work. [2] The updated classification of neonatal levels by the American Academy of Pediatrics (AAP) includes a Level IV.

Changes in neonatal care

Neonatal care became a specialty in the United States in 1960 and in that same year, the first NICU was established in the United States. There have been some major changes in Neonatal Care over the past 120 years. Some of these changes include the invention of the incubator, changes in respiratory care and the development of surfactants.

The incubator

An incubator is a plastic dome-shaped machine designed as a crib that regulates a newborn infant's body temperature. The incubator is designed to allow the temperature to be adjusted according to the state of the baby's current body heat. A range of five types of incubators all serve different purposes in the neonatal intensive care unit. The closed-box incubator is used to prevent infection that could be contracted the outside of the box; it filtrates the air and keeps the moisture fresh. The double-walled incubator keeps heat inside the box. Servo-controlled incubators are controlled by skin detectors which are designed to recognize the loss or gain of body heat and make adjustments to maintain the correct temperature. The open box incubator produces heat from beneath the baby to keep it warm. Portable incubators transport the newborn to and from different parts of the hospital. [1] In 1880, Dr. Tarnier was convinced that the maintenance of internal temperature was key to the premature infant's survival. This led him to introduce the first human incubator. Inspired by chicken eggs hatching in an incubator, he asked a zoo keeper to design a similar incubator for premature infants. Dr. Delee expanded the use and function of the incubator by incorporating an oxygen chamber and an electric controlled thermostat which allowed the incubator to be transported in ambulances. [6]

Respiratory care

Administration of oxygen assists and generates oxygen intake for neonates. Oxygen administration began with a metal forked device in the nostrils, and it is now administered through thin plastic tubes in the nostrils, also known as nasal cannula. The first ventilation of an infant was in 1961 in a positive pressure situation, and mechanical ventilation was improved in 1971. Mechanical ventilation is the process in which a machine, attached to the patient, regulates breathing by pumping air in and out of the lungs. Another type of breathing mechanism used is the continuous positive airway pressure (CPAP) mask which attaches to the face to help with breathing. These masks were first used in 1973 as an alternate less invasive form of support. [1]

Surfactants

A surfactant allows a substance to get "wet" to help another substance dissolve. In 1910, the first study of the use of surfactants on infants took place in Japan. Surfactant therapy since has improved the infant mortality rate by 50%. Surfactants combined with the least invasive respiratory therapy (bubble CPAP or nasal CPAP) has greatly improved the infant mortality rate in the US.[ citation needed ]

Family involvement (United States)

In the later 70s, family involvement in treatment became a major addition to patient treatment plans. This decade allowed for upgrades in visiting hours. Hours were expanded and siblings and fathers were encouraged to assist the mother in physical treatment. Many studies showed that with the higher frequency of family interaction such as bottle feeding, skin-to-skin contact, and overall baby holding, and support allowed for patients to have overall major health improvements which eventually lead to a decreasing need for ventilators and quicker discharge rates. [7]

Qualifications and requirements

United States

Healthcare institutions have varying entry-level requirements for neonatal nurses. Neonatal nurses are Registered Nurses (RNs), and therefore must have an Associate of Science in Nursing (ASN) or Bachelor of Science in Nursing (BSN) degree. Some countries or institutions may also require a midwifery qualification. [8] Some institutions may accept newly graduated RNs who have passed the NCLEX exam; others may require additional experience working in adult-health or medical/surgical nursing. [2]

Some countries offer postgraduate degrees in neonatal nursing, such as the Master of Science in Nursing (MSN) and various doctorates. A nurse practitioner may be required to hold a postgraduate degree. [8] The National Association of Neonatal Nurses recommends two years' experience working in a NICU before taking graduate classes. [2]

As with any registered nurse, local licensing or certifying bodies as well as employers may set requirements for continuing education. [2]

There are no mandated requirements to becoming an RN in a NICU, although neonatal nurses must complete the Neonatal Resuscitation Program. Some units prefer new graduates who do not have experience in other units, so they may be trained in the specialty exclusively, while others prefer nurses with more experience.

Intensive care nurses receive intensive didactic and clinical orientation, in addition to their general nursing knowledge, to provide highly specialized care for critical patients. Their competencies include the administration of high-risk medications, management of high-acuity patients requiring ventilator support, surgical care, resuscitation, advanced interventions such as extracorporeal membrane oxygenation or hypothermia therapy for neonatal encephalopathy procedures, as well as chronic-care management or lower acuity cares associated with premature infants such as feeding intolerance, phototherapy, or administering antibiotics. NICU RNs undergo annual skills tests and are subject to additional training to maintain contemporary practice.

Europe

The first step to qualify is to complete a nursing degree. To gain entry into a nursing degree, it is required to have at least GCSE (A-C) in English, Mathematics and a science-based subject, and two to three A-levels with one being in a biological science. [9]

United Kingdom

You must complete a 3 year degree program in nursing or midwifery and be either a RN(adult), RN(child) or a RM. Once a registered practitioner you can work in special care and some high dependency areas. It is a requirement to complete a recognized neonatal intensive care course to become qualified in specialty (QIS) to care for intensive care babies and to supervise other nurses.

Australia

In Australia, a neonatal nurse first needs to be a Registered Nurse (RN) or Midwife.

Two years of nursing experience are needed, as is practical experience and employment in the neonatal unit before being eligible to undertake postgraduate studies in neonatal nursing. This usually requires undertaking a Graduate Diploma Degree in Clinical Nursing. [10]

Academy of Neonatal Nursing

The Academy of Neonatal Nursing was founded in 2001 and serves as a professional organization for neonatal nurses. Nurses who belong to the organization have the ability to locate continued education, apply for scholarships and awards, and receive other benefits. They can also receive the Academy's healthcare journal, Neonatal Network .

APGAR scoring

All nurses working in a birthing center have an important role in assessing the newborn immediately after birth. The assessment of the neonate's appearance (colour), pulse (heart rate), grimace (in response to unpleasant stimuli such as bulb suctioning the pharynx), activity (muscle tone and/or movement), and respiratory effort via the APGAR scoring system is essential to guide the baby's care (see Understanding the APGAR scoring system). The nurse is often directly responsible for assigning the APGAR scores at 1 and 5 minutes of life. Each of the five assessment areas is given a score of 0, 1, or 2. The maximum score possible is 10. Scores of 7 or above are considered normal for full-term newborns. If the total score is below 7, or any area is scored 0 at 5 minutes of life, resuscitation efforts and scoring should continue every 5 minutes until 20 minutes of life. At 10 minutes neonates with an APGAR score of 3 or lower are at risk of having neurological dysfunctions and cerebral palsy in the future although there is no guarantee. Despite how every individual's case varies; as time goes by with the score not improving the risk becomes higher. However, there are numerous other factors to take into consideration when determining future complications, an APGAR score cannot do it alone. [11]

Beyond assessing the five components that make up the APGAR score, it's essential to understand its meaning. The APGAR score assigned at 1 minute of life reflects how the fetus tolerated the in utero environment and/or the labor and delivery process. All subsequent APGAR scores reflect the newborn's response to interventions during the transition from intrauterine to extra-uterine life. There are, however, multiple different factors that can impact the APGAR score which include anesthesia, gestational age and initial lower oxygen. [11] These nursing interventions include keeping the baby warm, stimulating the baby to breathe, giving breaths to the baby who isn't breathing well, and performing chest compression if needed. [1]

Apgar score Scale for newborn viability

The Apgar score is a quick way for doctors to evaluate the health of all newborns at 1 and 5 minutes after birth and in response to resuscitation. It was originally developed in 1952 by an anesthesiologist at Columbia University, Dr. Virginia Apgar, as way to address the need for a standardized way to evaluate infants shortly after birth.

Infant respiratory distress syndrome Human disease affecting newborns

Infantile respiratory distress syndrome (IRDS), also called respiratory distress syndrome of newborn, or increasingly surfactant deficiency disorder (SDD), and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs. It can also be a consequence of neonatal infection and can result from a genetic problem with the production of surfactant-associated proteins.

March of Dimes American nonprofit organization

March of Dimes is a United States nonprofit organization that works to improve the health of mothers and babies. The organization was founded by President Franklin D. Roosevelt in 1938, as the National Foundation for Infantile Paralysis, to combat polio. The name "March of Dimes" was coined by Eddie Cantor. After funding Jonas Salk's polio vaccine, the organization expanded its focus to the prevention of birth defects and infant mortality. In 2005, as preterm birth emerged as the leading cause of death for children worldwide, research and prevention of premature birth became the organization's primary focus.

Kangaroo care

Kangaroo care also called skin-to-skin contact (SSC), is a technique of newborn care where babies are kept chest-to-chest and skin-to-skin with a parent, typically their mother.

Neonatology Medical care of newborns, especially the ill or premature

Neonatology is a subspecialty of pediatrics that consists of the medical care of newborn infants, especially the ill or premature newborn. It is a hospital-based specialty, and is usually practised in neonatal intensive care units (NICUs). The principal patients of neonatologists are newborn infants who are ill or require special medical care due to prematurity, low birth weight, intrauterine growth restriction, congenital malformations, sepsis, pulmonary hypoplasia or birth asphyxia.

Neonatal intensive care unit Intensive care unit specializing in the care of ill or premature newborn infants

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. Neonatal refers to the first 28 days of life. Neonatal care, as known as specialized nurseries or intensive care, has been around since the 1960s.

Perinatal asphyxia is the medical condition resulting from deprivation of oxygen to a newborn infant that lasts long enough during the birth process to cause physical harm, usually to the brain. It is also the inability to establish and sustain adequate or spontaneous respiration upon delivery of the newborn. It remains a serious condition which causes significant mortality and morbidity. It is an emergency condition and requires adequate and quick resuscitation measures. Perinatal asphyxia is also an oxygen deficit from the 28th week of gestation to the first seven days following delivery. It is also an insult to the fetus or newborn due to lack of oxygen or lack of perfusion to various organs and may be associated with a lack of ventilation. In accordance with WHO, perinatal asphyxia is characterised by: profound metabolic acidosis, with a PH < 7.20 on umbilical cord arterial blood sample, persistence of an APGAR score of 3 at the 5th minute, clinical neurologic sequelae in the immediate neonatal period, or evidence of multiorgan system dysfunction in the immediate neonatal period. Hypoxic damage can occur to most of the infant's organs, but brain damage is of most concern and perhaps the least likely to quickly or completely heal. In more pronounced cases, an infant will survive, but with damage to the brain manifested as either mental, such as developmental delay or intellectual disability, or physical, such as spasticity.

Pediatric nursing is part of the nursing profession, specifically revolving around the care of neonates and children up to adolescence. The word, pediatrics, comes from the Greek words 'paedia' (child) and 'iatrike' (physician). 'Paediatrics' is the British/Australian spelling, while 'pediatrics' is the American spelling.

Bronchopulmonary dysplasia Medical condition

Bronchopulmonary dysplasia is a chronic lung disease in which premature infants, usually those who were treated with supplemental oxygen, require long-term oxygen. The alveoli that are present tend to not be mature enough to function normally. It is more common in infants with low birth weight (LBW) and those who receive prolonged mechanical ventilation to treat respiratory distress syndrome (RDS). It results in significant morbidity and mortality. The definition of BPD has continued to evolve primarily due to changes in the population, such as more survivors at earlier gestational ages, and improved neonatal management including surfactant, antenatal glucocorticoid therapy, and less aggressive mechanical ventilation.

Newborn transport

Newborn transport is used to move premature and other sick infants from one hospital to another, such as a medical facility that has a neonatal intensive care unit and other services. Neonatal transport services such as NETS use mobile intensive care incubators fitted with mechanical ventilators, infusion pumps and physiological monitors capable of being used in a mobile environment. These transport systems seek to emulate the environment of a neonatal intensive care and permit uninterrupted care to occur in a referring hospital and then during the journey by road or air ambulance. Power and medical gas supplies are carried within the system as well as making use of external supplies; as available. Infant transport systems commonly weigh over 100 kg and present a challenge to vehicle operators in terms of weight, manual handling, crashworthiness and power consumption.

Critical care nursing

Critical care nursing is the field of nursing with a focus on the utmost care of the critically ill or unstable patients following extensive injury, surgery or life threatening diseases. Critical care nurses can be found working in a wide variety of environments and specialties, such as general intensive care units, medical intensive care units, surgical intensive care units, trauma intensive care units, coronary care units, cardiothoracic intensive care units, burns unit, paediatrics and some trauma center emergency departments. These specialists generally take care of critically ill patients who require mechanical ventilation by way of endotracheal intubation and/or titratable vasoactive intravenous medications.

Bubble CPAP is a non-invasive ventilation strategy for newborns with infant respiratory distress syndrome (IRDS). It is one of the methods by which continuous positive airway pressure (CPAP) is delivered to a spontaneously breathing newborn to maintain lung volumes during expiration. With this method, blended and humidified oxygen is delivered via short binasal prongs or a nasal mask and pressure in the circuit is maintained by immersing the distal end of the expiratory tubing in water. The depth to which the tubing is immersed underwater determines the pressure generated in the airways of the infant. As the gas flows through the system, it “bubbles” out and prevents buildup of excess pressures.

Surfactant therapy is the medical administration of exogenous surfactant. Surfactants used in this manner are typically instilled directly into the trachea. When a baby comes out of the womb and the lungs are not developed yet, they require administration of surfactant in order to process oxygen and survive. This condition that the baby has is called newborn respiratory distress syndrome, and it is treatable. Surfactant coat the smallest parts of the lungs called the alveoli and helps for oxygen to go in and for carbon dioxide to go out. How surfactant does this is by not allowing the alveoli to collapse and to retain their inflated shape when the baby exhales.

The Bloxsom air lock was an incubator used in the treatment of respiratory distress among newly born infants in the 1950s. The device attempted to mimic the rhythm of uterine contractions, which were thought to have a role in stimulating fetal breathing. The device was developed by Dr. Allan Bloxsom, a pediatrician at St. Joseph Hospital and Baylor College of Medicine in Houston, Texas. At its peak, the device was utilized in more than 700 hospitals.

Neonatal nurse practitioner

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 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.

Neonatal resuscitation

Neonatal resuscitation, also known as newborn resuscitation, is an emergency procedure focused on supporting approximately 10% of newborn children who do not readily begin breathing, putting them at risk of irreversible organ injury and death. Through positive airway pressure, and in severe cases chest compressions, medical personnel certified in neonatal resuscitation can often stimulate neonates to begin breathing on their own, with attendant normalization of heart rate.

Herbert Barrie Consultant paediatrician

Herbert Barrie, was a British consultant paediatrician and a leading figure in neonatology. He was a pioneer in the emerging specialty of paediatrics and neonatal medicine; and he developed one of the first neonatal intensive care units in London.
