Prematurity (3) (2)

NUR 113
Page 2: Overview
Definition of Prematurity: Birth before 37 weeks of gestation (after 20 weeks).
Late Preterm: 34 to 36 weeks; infants can perform some normal newborn behaviors.
Rise in Multiple Birth Rates: Accounts for 12% of all births in the U.S.
Survival Rates: Improving at younger gestational ages.
Page 3: Risk Factors
Maternal Factors:
Gestational Hypertension.
Closely Spaced Pregnancies.
Adolescent Pregnancy.
Lifestyle Factors:
Lack of Prenatal Care.
Maternal Substance Use, including smoking.
Medical History Factors:
Previous Preterm Deliveries.
Uterine Abnormalities.
Cervical Incompetence.
Placenta Previa.
Other Factors:
Preterm Labor.
Premature Rupture of Membranes (PROM).
Page 4: Complications
Respiratory Distress Syndrome (RDS):
Inability to produce adequate surfactant, leading to poor gas exchange and ventilator failure.
Patent Ductus Arteriosus (PDA):
Condition where ductus arteriosus fails to close after birth due to neonatal hypoxia, resulting in murmur and abnormal blood pressure levels, leading to pulmonary congestion.
Apnea of Prematurity:
Results from immature neurological and chemical mechanisms.
Intraventricular Hemorrhage (IVH):
Bleeding between the brain and skull causing potential brain damage, leading to conditions like hydrocephalus.
Page 5: Gastrointestinal Complications
Aspiration Risks:
Poor gag reflex and inability to suck or swallow effectively (common in those less than 32-34 weeks).
Nutritional Challenges:
Small stomach capacity; difficulty meeting high caloric & fluid needs.
Potential deficiencies in lactose, calcium, and phosphorus.
Necrotizing Enterocolitis (NEC):
Inflammatory disease of the gastrointestinal mucosa leading to necrosis; can necessitate surgical removal of parts of the intestines.
Page 6: Renal Complications
Kidney Immaturity:
Such immaturity leads to fluid & electrolyte imbalance.
Lower Glomerular Filtration Rate (GFR) and reduced renal blood flow.
Careful dose management for medications due to immaturity affecting drug excretion.
Page 7: Newborn Infection (Sepsis)
Definition of Newborn Sepsis:
Presence of microorganisms in the blood or tissues within the first month of life; signs can be subtle.
Causes:
Can be contracted before, during, or after delivery; preterm infants are at higher risk due to limited immunity.
Prevention Strategies:
Maternal infection screening, proper antiseptic techniques, and antibiotics for newborns.
Page 8: Newborn Infection - Data Collection
Signs of Infection to Monitor:
Temperature instability, drainage (from eyes/nose), poor feeding, vomiting and diarrhea, hypo/hyperglycemia.
Physical Signs: Abdominal distention, apnea, nasal flaring, pallor, jaundice, tachycardia or bradycardia, hypotension, irritability, lethargy.
Page 9: Newborn Infection - Nursing Care
Important Assessments:
CBC with differential, C-reactive protein, electrolytes.
Cultures:
Blood, urine, and Cerebrospinal fluid cultures to identify infections.
Monitoring:
Continuous vital sign monitoring and assessments of input & output, including daily weight checks.
IV Therapy Requirements:
Fluids, electrolytes, and necessary antibiotics or antivirals.
Page 10: Nutrition
Feeding Regimens:
Should be weight and capacity-based; early feedings are beneficial.
High Calorie Needs:
Supplements may be required for weight gain of 20 to 30 g/day.
Feeding Methods:
Breastfeeding, bottle feeding, and gavage methods based on gestational age and stability of the infant.
Page 11: Cue-Based Feeding
Indicators for Readiness:
Self-regulation, comfort, and physiological stability.
Parental Involvement:
Encouraged in feeding preterm infants to enhance bonding and feeding success.
Assessment of Feeding Cues:
Monitor behaviors like rooting or hand-to-mouth motions, respiratory patterns, and vital signs.
Page 12: Long Term Complications
Retinopathy of Prematurity (ROP):
Abnormal growth of retinal blood vessels causing vision impairment; associated with oxygen therapy.
Bronchopulmonary Dysplasia (BPD):
Persistent lung disease requiring long-term oxygen and ventilation support.
Developmental Delays:
Risk of motor, sensory, and cognitive disabilities including CP and hearing issues.
Page 13: Collaboration in Care
Involvement of Multiple Professionals:
RN, LPN, PA, NP, respiratory therapist, dietitians, social workers, neonatologists, and various specialists as needed.
Page 14: Data Collection - Respiratory Assessment
Observe for:
Periodic breathing and signs like retractions or nasal flaring.
Skin:
Characteristics such as reddened or translucent appearance, suitable development indicators.
Page 15: Data Collection - Physical Characteristics
Nails Soft and short; testes may not be descended. Abdominal assessments and muscle tone central to monitoring.
Page 16: Implementation - Initial Assessments
Conduct rapid initial assessments covering respiratory status and vital signs.
Assess for potential airway obstructions frequently.
Page 17: Implementation - Respiratory Distress Indicators
Signs include cyanosis, retractions, nasal flaring, grunting, tachypnea, diminished air entry, apneic episodes.

Strategies to minimize heat loss and maintain appropriate body temperatures in preterm infants.
Page 19: Implementation - Hydration & Nutrition Monitoring
Focus on Signs of dehydration and adjust feeding modalities based on tolerance.
Page 20: NCLEX Question on NG Feeding
Preferred method for verifying tube placement in nasal feedings.
Page 21: NCLEX Answer Explanation
Answer: B. Verify gastric pH is less than 5.5 for correct placement; rationale explaining other methods.
Page 22: Implementation - Feeding Intolerance Signs
Indicators include increased gastric residuals, abdominal distention, and abnormal stool patterns.
Page 23: NCLEX Question on Medications for GER
Identify which medication is a proton pump inhibitor for gastroesophageal reflux.
Page 24: NCLEX Answer Explanation
Omeprazole (Prilosec) is the proton pump inhibitor; explanations on other medications provided.
