The initial months of life, particularly the newborn phase, are critical as infants adapt physically to life outside the womb, learning essential functions like breathing, feeding, and waste elimination. Throughout the first year, rapid maturation continues, with infants acquiring new skills through environmental interaction. However, for premature infants, this transition is fraught with unique challenges and vulnerabilities, necessitating specialized nursing care.
Physical development in all newborns encompasses weight gain, sensory refinement (eyesight, hearing, smell, taste, touch), reflex development, and motor skill acquisition. The first week of life is especially precarious, with a significant majority of neonatal deaths occurring during this period. A major factor contributing to newborn mortality, and particularly morbidity, is preterm birth. Prematurity is also closely linked to intrapartum-related issues, infections, and congenital anomalies.
Nurses play a pivotal role in the evaluation and continuous monitoring of all neonates, especially those born prematurely. This monitoring begins with the Apgar score, a rapid assessment tool evaluating respiratory effort, heart rate, muscle tone, reflexes, and color. Subsequent assessments include growth measurements and laboratory analyses. Beyond physical assessments, nurses are crucial educators and sources of support for parents as they navigate the complexities of parenthood, particularly when caring for a premature infant. Nurses guide parents in feeding techniques, bathing practices, and understanding and responding to their newborn’s cues.
This article delves into essential nursing diagnoses relevant to newborn care, with a particular emphasis on prematurity. We will explore how prematurity significantly influences common newborn nursing diagnoses and necessitates tailored care plans to optimize outcomes for these vulnerable infants.
Nursing Process for Premature Infants
The nursing process is fundamental to providing comprehensive care for premature infants. Nurses utilize this systematic approach to assess, diagnose, plan, implement, and evaluate care, ensuring individualized and effective interventions. For premature infants, the nursing process is intensified due to their physiological immaturity and increased vulnerability.
Assessment
A thorough assessment of the premature infant is the cornerstone of effective nursing care. This includes:
- Gestational Age Assessment: Accurately determining gestational age is crucial as it dictates the degree of organ system maturity and potential complications. Tools like the Ballard score are used.
- Physical Examination: A head-to-toe assessment focusing on vital signs, respiratory status (including signs of respiratory distress syndrome – RDS, common in premature infants), cardiovascular function, thermoregulation, nutritional status, skin integrity, and neurological reflexes.
- Developmental Assessment: While milestones are adjusted for prematurity, assessing developmental reflexes and responsiveness provides a baseline and monitors progress.
- Environmental Assessment: Evaluating the NICU environment, including temperature, humidity, and infection control measures, is vital for minimizing risks to the premature infant.
- Parental Assessment: Understanding parental knowledge, coping mechanisms, and support systems is essential for providing holistic family-centered care.
Nursing Diagnosis
Based on the assessment findings, nurses formulate nursing diagnoses. For premature infants, these diagnoses often revolve around the challenges associated with their immature physiological systems. Common nursing diagnoses, significantly impacted by prematurity, include:
- Imbalanced Nutrition: Less Than Body Requirements: Premature infants often struggle with feeding due to underdeveloped sucking and swallowing reflexes, leading to inadequate nutrient intake.
- Risk for Hypothermia: Limited subcutaneous fat, a high surface area to volume ratio, and immature thermoregulation mechanisms place premature infants at high risk for heat loss.
- Risk for Impaired Gas Exchange: Respiratory Distress Syndrome (RDS), caused by surfactant deficiency in immature lungs, is a leading concern in premature infants, leading to impaired oxygenation and ventilation.
- Risk for Impaired Skin Integrity: The delicate and underdeveloped skin of premature infants is highly susceptible to breakdown and infection.
- Risk for Infection: Immature immune systems and prolonged hospital stays in the Neonatal Intensive Care Unit (NICU) increase the risk of nosocomial infections in premature infants.
Planning
Care planning for premature infants is collaborative and multidisciplinary, involving physicians, nurses, respiratory therapists, dietitians, and parents. Plans are individualized, focusing on:
- Stabilization: Addressing immediate life-threatening issues like respiratory distress, hypothermia, and hypoglycemia.
- Supportive Care: Providing optimal nutrition, thermoregulation, respiratory support, and infection prevention.
- Developmental Care: Minimizing environmental stressors, promoting neurodevelopment, and facilitating parent-infant bonding.
- Family Education and Support: Empowering parents with knowledge and skills to care for their premature infant, both in the hospital and at home.
Implementation
Nursing interventions are meticulously implemented and continuously monitored. These interventions are tailored to the specific nursing diagnoses and the unique needs of the premature infant. Examples include:
- Nutritional Support: Initiating and managing parenteral or enteral nutrition, supporting breastfeeding or bottle-feeding as appropriate, and monitoring growth and weight gain.
- Thermoregulation: Utilizing incubators, radiant warmers, and swaddling to maintain a neutral thermal environment.
- Respiratory Support: Administering oxygen therapy, CPAP, or mechanical ventilation as needed, monitoring respiratory status and ABGs.
- Skin Care: Implementing meticulous skin care protocols, using specialized dressings and barrier creams, and minimizing tape and adhesive use.
- Infection Prevention: Adhering to strict hand hygiene, implementing bundle care for central lines and ventilators, and monitoring for signs of infection.
- Developmental Interventions: Positioning, swaddling, minimizing noise and light, and promoting kangaroo care (skin-to-skin contact).
- Parent Education: Providing ongoing education on infant care, feeding, medication administration, and recognizing signs of illness.
Evaluation
Continuous evaluation is integral to the nursing process. Nurses regularly assess the premature infant’s response to interventions, monitor progress towards expected outcomes, and adjust the care plan as needed. Evaluation includes:
- Monitoring achievement of expected outcomes: Assessing if the infant is gaining weight appropriately, maintaining stable temperature, achieving adequate oxygenation, maintaining skin integrity, and remaining free from infection.
- Assessing for complications: Closely monitoring for potential complications of prematurity, such as RDS, intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), and retinopathy of prematurity (ROP).
- Evaluating parental understanding and coping: Assessing parents’ ability to provide care, their emotional well-being, and their access to support resources.
Nursing Care Plans for Premature Infants: Addressing Key Diagnoses
Building upon the nursing process, specific nursing care plans are developed to address the most pertinent nursing diagnoses in premature infants. These plans provide a framework for prioritizing assessments and interventions, guiding nurses in delivering evidence-based care.
Imbalanced Nutrition: Less Than Body Requirements in Premature Infants
Premature infants are particularly vulnerable to imbalanced nutrition due to a confluence of factors. Their increased metabolic demands, coupled with underdeveloped digestive systems and feeding reflexes, often lead to inadequate nutrient intake. Conditions such as necrotizing enterocolitis (NEC), a serious intestinal condition more prevalent in premature infants, can further complicate nutritional management.
Nursing Diagnosis: Imbalanced Nutrition: Less Than Body Requirements
Related to (Specific to Prematurity):
- Prematurity and gestational age less than 37 weeks
- Underdeveloped sucking and swallowing reflexes
- Increased metabolic rate and energy expenditure
- Limited gastric capacity
- Potential for necrotizing enterocolitis (NEC)
- Respiratory distress and increased work of breathing interfering with feeding
As evidenced by:
- Weight below the 10th percentile for gestational age
- Poor weight gain or weight loss
- Lethargy and decreased muscle tone
- Weak or absent suck and swallow reflex
- Poor feeding tolerance, vomiting, or abdominal distention
- Electrolyte imbalances and hypoglycemia
Expected outcomes:
- Premature infant will demonstrate adequate weight gain of 15-20 grams/kg/day.
- Premature infant will tolerate feedings without signs of distress (e.g., vomiting, abdominal distention).
- Premature infant will maintain stable blood glucose levels.
- Premature infant will exhibit age-appropriate developmental progress in feeding skills.
Assessment (Specific to Prematurity):
- Assess gestational age and birth weight: Provides a baseline for nutritional needs and expected growth patterns. Extremely premature infants have significantly higher nutritional needs and feeding challenges.
- Evaluate sucking and swallowing reflexes: Premature infants may have weak or uncoordinated suck and swallow reflexes, impacting oral feeding ability. Assess the strength and coordination of these reflexes.
- Monitor feeding tolerance: Observe for signs of feeding intolerance such as vomiting, gagging, abdominal distention, and changes in stool pattern. Premature infants are at higher risk for NEC, and feeding intolerance can be an early sign.
- Assess caloric and fluid intake: Accurately track intake from parenteral and enteral sources to ensure adequate provision of nutrients and fluids to meet high metabolic demands.
- Monitor blood glucose levels: Premature infants are prone to hypoglycemia due to limited glycogen stores and immature glucose regulation. Frequent monitoring is essential.
Interventions (Specific to Prematurity):
- Initiate parenteral nutrition (PN) as prescribed: PN provides essential nutrients intravenously when enteral feeding is not initially tolerated or sufficient, common in very premature infants.
- Advance enteral feedings slowly and cautiously: Begin with minimal enteral nutrition (MEN) and gradually increase volume and concentration as tolerated, minimizing the risk of NEC.
- Consider orogastric or nasogastric tube feeding: Tube feeding may be necessary to provide consistent nutrition when oral feeding is insufficient or unsafe due to weak suck/swallow or respiratory distress.
- Provide non-nutritive sucking during tube feedings: Non-nutritive sucking (pacifier) can promote gastrointestinal motility and improve feeding readiness.
- Promote breastfeeding or breast milk feeding: Breast milk is highly beneficial for premature infants, providing immunoglobulins and optimal nutrients. Support mothers in pumping and breastfeeding when feasible.
- Monitor weight, length, and head circumference regularly: Growth parameters are crucial indicators of nutritional adequacy in premature infants. Plot growth on gestational age-appropriate growth charts.
- Collaborate with a dietitian: A registered dietitian specializing in neonates can provide expert guidance on nutritional management, feeding advancement, and individualized nutritional plans.
Risk for Hypothermia in Premature Infants
Premature infants are exceptionally susceptible to hypothermia due to their physiological characteristics. Their large surface area relative to body mass, minimal subcutaneous fat, and limited brown fat reserves impede their ability to generate and conserve heat effectively. Furthermore, their immature thermoregulatory center in the brain is less efficient.
Nursing Diagnosis: Risk for Hypothermia
Related to (Specific to Prematurity):
- Prematurity and gestational age less than 37 weeks
- Decreased subcutaneous fat and brown fat
- Large surface area to body mass ratio
- Immature thermoregulatory center
- Thin epidermis and increased evaporative heat loss
As evidenced by: (Risk diagnosis – no AEB)
Expected outcomes:
- Premature infant will maintain a body temperature between 97.7°F and 99.5°F (36.5°C and 37.5°C).
- Premature infant will exhibit stable vital signs within normal limits for gestational age.
- Premature infant will demonstrate warm and dry skin.
Assessment (Specific to Prematurity):
- Continuously monitor body temperature: Use skin temperature probes and/or rectal temperatures as indicated. Frequent monitoring is essential due to rapid heat loss in premature infants.
- Assess environmental temperature and humidity: Maintain a neutral thermal environment in the NICU. Incubator temperature and humidity should be adjusted based on the infant’s needs.
- Observe for signs of cold stress: Monitor for signs such as lethargy, poor feeding, hypoglycemia, respiratory distress, and mottling of the skin, which indicate the infant is expending energy to maintain warmth.
- Assess skin color and peripheral perfusion: Cyanosis, pallor, and cool extremities can indicate hypothermia and poor peripheral circulation.
Interventions (Specific to Prematurity):
- Place infant in a pre-warmed incubator or radiant warmer: Incubators provide a controlled thermal environment, while radiant warmers provide direct heat. Utilize servo-control modes to automatically adjust heat output.
- Maintain appropriate incubator temperature and humidity: Adjust incubator settings based on the infant’s temperature and gestational age. Humidity reduces evaporative heat loss.
- Utilize heat shields and double-walled incubators: These measures minimize radiant heat loss to the environment.
- Apply a hat to the infant’s head: A significant amount of heat is lost from the scalp. A hat helps conserve heat.
- Employ skin-to-skin care (kangaroo care) with the parent: Kangaroo care provides warmth, promotes bonding, and stabilizes infant temperature.
- Warm and humidify inspired air: If the infant is receiving respiratory support, ensure that inspired gases are warmed and humidified to prevent heat and moisture loss.
- Minimize exposure during procedures: Cluster care to minimize handling and exposure to cooler ambient temperatures during procedures.
Risk for Impaired Gas Exchange in Premature Infants
Respiratory Distress Syndrome (RDS), primarily caused by surfactant deficiency due to lung immaturity, is a major respiratory complication in premature infants. This deficiency leads to alveolar collapse, decreased lung compliance, and impaired gas exchange. Other factors such as apnea of prematurity, underdeveloped respiratory muscles, and potential for infection further contribute to the risk of impaired gas exchange.
Nursing Diagnosis: Risk for Impaired Gas Exchange
Related to (Specific to Prematurity):
- Prematurity and gestational age less than 37 weeks
- Surfactant deficiency and Respiratory Distress Syndrome (RDS)
- Apnea of prematurity
- Underdeveloped respiratory muscles
- Increased risk of respiratory infections (e.g., pneumonia)
As evidenced by: (Risk diagnosis – no AEB)
Expected outcomes:
- Premature infant will maintain oxygen saturation levels within prescribed limits (typically 90-95%).
- Premature infant will exhibit respiratory rate and effort within normal limits for gestational age.
- Premature infant will have clear breath sounds bilaterally.
- Premature infant will maintain arterial blood gases (ABGs) within normal limits for gestational age.
Assessment (Specific to Prematurity):
- Continuously monitor respiratory rate, pattern, and effort: Observe for signs of respiratory distress such as tachypnea, retractions, nasal flaring, grunting, and apnea. These are common indicators of RDS and impaired gas exchange.
- Continuously monitor oxygen saturation (SpO2): Pulse oximetry provides continuous monitoring of oxygenation. Maintain SpO2 within prescribed target range, often higher for premature infants than term infants.
- Auscultate breath sounds: Assess for adventitious breath sounds such as crackles or wheezes, which may indicate fluid overload or airway obstruction. Diminished breath sounds can suggest atelectasis or pneumothorax.
- Monitor arterial blood gases (ABGs) as ordered: ABGs provide a direct measure of oxygenation (PaO2), ventilation (PaCO2), and acid-base balance.
- Assess for signs of cyanosis: Central cyanosis (around the mouth and trunk) is a late sign of hypoxemia and requires immediate intervention.
Interventions (Specific to Prematurity):
- Administer supplemental oxygen as prescribed: Oxygen therapy is often necessary to maintain adequate oxygenation. Delivery methods may include nasal cannula, CPAP, high-flow nasal cannula, or mechanical ventilation.
- Administer surfactant replacement therapy as ordered: Exogenous surfactant helps improve lung compliance and gas exchange in infants with RDS. Administer via endotracheal tube.
- Provide respiratory support as needed (CPAP, mechanical ventilation): CPAP provides continuous positive airway pressure to keep alveoli open. Mechanical ventilation may be required for severe RDS or apnea.
- Position infant to optimize lung expansion: Prone positioning can improve oxygenation and lung mechanics in some premature infants.
- Suction airway as needed: Gentle suctioning removes secretions and maintains airway patency.
- Monitor for complications of respiratory support: Closely monitor for complications such as pneumothorax, bronchopulmonary dysplasia (BPD), and infection.
- Provide chest physiotherapy and postural drainage as indicated: These techniques help mobilize and clear airway secretions.
Risk for Impaired Skin Integrity in Premature Infants
The skin of premature infants is structurally and functionally immature. The epidermis is thin and fragile, providing limited barrier function. Reduced subcutaneous fat and increased permeability make their skin highly susceptible to injury, breakdown, and infection. Adhesive tape, frequent procedures, and moisture from incubators or diapers can further compromise skin integrity.
Nursing Diagnosis: Risk for Impaired Skin Integrity
Related to (Specific to Prematurity):
- Prematurity and gestational age less than 37 weeks
- Thin and fragile epidermis
- Decreased subcutaneous fat
- Increased skin permeability
- Exposure to adhesive tape, frequent procedures, and moisture
As evidenced by: (Risk diagnosis – no AEB)
Expected outcomes:
- Premature infant will maintain intact skin integrity without evidence of breakdown or infection.
- Premature infant will exhibit normal skin turgor and color.
- Premature infant will be free from skin irritation and rash.
Assessment (Specific to Prematurity):
- Conduct daily skin assessments: Systematically assess skin condition, noting color, turgor, temperature, and presence of any lesions, redness, or breakdown. Pay particular attention to pressure points and areas exposed to adhesives or moisture.
- Assess gestational age and skin maturity: Extremely premature infants have the most fragile skin and require the most meticulous skin care.
- Monitor for signs of skin breakdown or infection: Early signs of skin breakdown include redness, blistering, and maceration. Signs of infection include increased redness, warmth, swelling, drainage, and fever.
- Evaluate diaper area frequently: Diaper dermatitis is common in premature infants due to increased skin sensitivity and prolonged diaper use.
Interventions (Specific to Prematurity):
- Handle skin gently and minimize friction: Use gentle touch when handling and repositioning the infant. Avoid rubbing or scrubbing the skin.
- Use emollients and barrier creams as prescribed: Emollients hydrate the skin and improve barrier function. Barrier creams protect the skin from moisture and irritants, especially in the diaper area.
- Minimize use of adhesive tape: Use alternative methods for securing lines and tubes whenever possible. If tape is necessary, use silicone-based adhesives and remove them gently.
- Utilize appropriate dressings for wounds or skin breakdown: Select dressings that promote moist wound healing and protect the fragile skin.
- Keep skin clean and dry: Gently cleanse skin with warm water and mild, pH-neutral cleansers as needed. Pat skin dry and avoid excessive bathing.
- Change diapers frequently: Prompt diaper changes prevent prolonged exposure to urine and feces, reducing the risk of diaper dermatitis.
- Position and support to minimize pressure: Use pressure-redistributing mattresses and position the infant to avoid prolonged pressure on bony prominences.
- Maintain appropriate incubator humidity: Adequate humidity helps prevent skin dryness and cracking.
Risk for Infection in Premature Infants
Premature infants are at a significantly heightened risk of infection due to their immature immune systems. They have decreased levels of maternal antibodies, reduced neutrophil function, and underdeveloped cell-mediated immunity. Prolonged hospitalization in the NICU exposes them to a greater risk of nosocomial infections. Infections, such as sepsis and pneumonia, are major causes of morbidity and mortality in this population.
Nursing Diagnosis: Risk for Infection
Related to (Specific to Prematurity):
- Prematurity and immature immune system
- Decreased transplacental transfer of maternal antibodies
- Reduced neutrophil function and immature cell-mediated immunity

Assessment (Specific to Prematurity):
- Monitor vital signs closely: Temperature instability (hypothermia or hyperthermia), tachycardia, and tachypnea can be early indicators of infection in premature infants.
- Observe for subtle signs of infection: Premature infants may present with non-specific signs of infection such as lethargy, poor feeding, irritability, glucose instability, and apnea. Be vigilant for subtle changes in behavior or condition.
- Assess for risk factors for infection: Identify risk factors such as prolonged rupture of membranes (PROM), maternal infection (e.g., chorioamnionitis), invasive procedures, and prolonged hospitalization.
- Monitor white blood cell count (WBC) and differential: Changes in WBC count and differential can indicate infection, although premature infants may have atypical responses.
- Monitor C-reactive protein (CRP) levels: CRP is an acute-phase reactant that increases in response to inflammation and infection.
Interventions (Specific to Prematurity):
- Adhere to strict hand hygiene protocols: Meticulous handwashing before and after any contact with the infant is paramount to prevent infection transmission.
- Implement infection control bundles: Utilize bundle care for central lines, ventilators, and urinary catheters to minimize infection risk.
- Maintain a clean NICU environment: Ensure proper cleaning and disinfection of equipment and surfaces in the NICU.
- Limit invasive procedures when possible: Minimize the use of invasive procedures and ensure aseptic technique when procedures are necessary.
- Promote breastfeeding: Breast milk provides immunoglobulins and other protective factors that help bolster the premature infant’s immune system.
- Administer prophylactic antibiotics as ordered: Prophylactic antibiotics may be indicated in certain high-risk situations, such as suspected sepsis or prolonged rupture of membranes.
- Monitor for and report any signs of infection promptly: Early detection and treatment of infection are critical to improving outcomes in premature infants.
- Educate parents on infection prevention measures: Teach parents about hand hygiene, limiting visitors when ill, and recognizing signs of infection in their infant.
Conclusion
Caring for premature infants demands a deep understanding of their unique vulnerabilities and specialized needs. By prioritizing accurate nursing diagnoses, particularly those influenced by prematurity, and implementing meticulously planned and executed care plans, nurses play an indispensable role in optimizing outcomes for these fragile newborns. Focusing on addressing imbalanced nutrition, preventing hypothermia, supporting gas exchange, maintaining skin integrity, and mitigating infection risk are paramount in the nursing care of premature infants.
