Nursing Management of Respiratory Distress Syndrome (RDS)

PART 1: Neonatal RDS (Hyaline Membrane Disease)

Pathophysiology Basis for Nursing Care

• Creasy & Resnik's Maternal-Fetal Medicine, p. 1786

1. Thermal Environment Management

• Place infant in an incubator or under a radiant warmer in a neutral thermal environment
• Cold stress increases oxygen consumption and worsens respiratory distress; maintain normothermia strictly
• Monitor temperature continuously

2. Respiratory Monitoring and Oxygen Therapy

• Maintain SpO2 between 90-95% and PaO2 between 50-80 mmHg
• Avoid both hyperoxia (risk of retinopathy of prematurity, BPD) and hypocarbia
• Monitor respiratory rate, work of breathing, use of accessory muscles, nasal flaring, grunting, and retractions
• Continuous pulse oximetry is mandatory
• Monitor for air leaks: pneumothorax and pneumomediastinum are common CPAP complications

3. CPAP Nursing Care

• Ensure correct prong/mask fit to prevent pressure injuries on nasal septum
• Maintain CPAP pressure as prescribed (typically 5-8 cm H2O)
• Reposition prongs regularly; check for nasal trauma
• Keep airway clear - suction as needed
• Monitor for CPAP failure (worsening FiO2 requirements, increasing apnea) and escalate
• Heated humidified high-flow nasal cannula (HHHFNC) and SNIPPV are alternatives shown equivalent to CPAP
• Creasy & Resnik's, p. 1786

4. Surfactant Therapy - Nursing Role

• Watch for rapid improvement in oxygenation - wean FiO2 promptly to avoid hyperoxia
• Monitor for endotracheal tube displacement, bradycardia, and desaturation during and after instillation
• Avoid suctioning for 1-2 hours after surfactant unless airway obstruction is suspected
• Assess breath sounds bilaterally for equal air entry

5. Cardiovascular and Hemodynamic Monitoring

• Monitor heart rate, blood pressure, peripheral perfusion continuously
• Watch for patent ductus arteriosus (PDA) - a common complication of RDS in preterm infants; signs include bounding pulses, widened pulse pressure, murmur
• Monitor blood gas values (ABG/capillary) regularly for acid-base balance

6. Infection Prevention and Antibiotics

• RDS cannot be clinically distinguished from early-onset sepsis; therefore:
  • Obtain blood culture and CBC with differential before starting antibiotics
  • Administer broad-spectrum antibiotics for 48 hours pending culture results
• Strict hand hygiene and infection control are essential in the NICU
• Maintain aseptic technique for all line and airway care

7. Fluid and Nutritional Management

• Restrict fluids initially (preterm kidneys cannot handle fluid overload - risk of pulmonary edema)
• Provide parenteral nutrition early; transition to enteral feeds when stable
• Monitor urine output (goal ≥ 1 mL/kg/hr), electrolytes, and blood glucose
• Watch for hypoglycemia (common in preterm infants)

8. Neuroprotection and Minimal Handling

• Practice minimal stimulation/handling - cluster care activities to reduce oxygen consumption and stress
• Keep environment calm: dim lights, reduce noise
• Ensure comfortable positioning (flexed midline position in nesting aids)

9. Family-Centered Care

• Provide clear, compassionate information to parents about RDS and prognosis
• Encourage skin-to-skin (kangaroo care) as soon as clinically stable - shown to improve outcomes
• Support breastfeeding initiation; expressed breast milk is protective
• Involve parents in care planning

PART 2: Acute Respiratory Distress Syndrome (ARDS) - Adult/Critical Care

1. Oxygenation and Ventilator Management

• Monitor P/F ratio (PaO2/FiO2) to gauge severity: mild (200-300), moderate (100-200), severe (<100)
• Lung-protective ventilation is the cornerstone: tidal volume 4-6 mL/kg predicted body weight, plateau pressure < 30 cmH2O
• Titrate PEEP to maintain oxygenation while minimizing overdistension
• Monitor for ventilator-induced lung injury (VILI) - barotrauma, volutrauma, atelectrauma
• Maintain SpO2 88-95% and PaO2 55-80 mmHg

2. Prone Positioning

• Requires a coordinated team (minimum 4-5 staff) for safe turning
• Secure all lines, ETT, drains, and catheters before turning
• Reposition head to alternate sides every 2 hours while prone
• Vigilantly prevent pressure injuries (face, knees, chest)
• Monitor for tube displacement, hemodynamic instability
• Eye care to prevent corneal abrasions
• Murray & Nadel's Textbook of Respiratory Medicine, p. 3219

3. Fluid Management

• Strict fluid balance monitoring (input/output charting every hour)
• Conservative fluid strategy (after initial resuscitation) reduces ventilator days
• Monitor for signs of fluid overload: worsening lung compliance, increasing FiO2 requirement, peripheral edema
• Daily weights

4. Sedation and Analgesia

• Maintain adequate sedation to prevent ventilator dyssynchrony and self-extubation
• Use validated sedation scales (RASS, SAS)
• Daily sedation interruption (SAT) - assess readiness to wean
• Neuromuscular blockade (cisatracurium) may be used in severe ARDS for first 48 hours - requires deep sedation monitoring and skin care

5. Infection Control and VAP Prevention Bundle

• Elevate head of bed 30-45 degrees at all times
• Oral care with chlorhexidine every 2-4 hours
• Subglottic suctioning via specialized ETT
• Hand hygiene before and after airway care
• Closed suction catheter systems
• Regular circuit changes per protocol

6. Nutritional Support

• Early enteral nutrition (within 24-48 hours) preferred over parenteral
• Prokinetic agents for gastric intolerance
• Monitor for abdominal distension and aspiration risk
• Continue enteral feeds during prone positioning if tolerated (consider post-pyloric feeding)

7. Monitoring and Ongoing Assessment

• Continuous monitoring: HR, BP, SpO2, RR, ETCO2 (if available), ventilator parameters
• Regular arterial blood gas analysis
• Assess breath sounds at least every 4 hours
• Monitor peak airway pressures and compliance trends (worsening compliance = deterioration)
• Watch for pneumothorax (sudden hemodynamic deterioration + decreased breath sounds)
• Track urine output and renal function (ARDS-associated AKI is common)

8. High-Flow Nasal Cannula (HFNC) in Early/Mild ARDS

• HFNC at flows 30-60 L/min provides heated, humidified high-FiO2 oxygen
• Monitor ROX index (SpO2/FiO2 ratio ÷ respiratory rate) - ROX < 4.88 at 2 hours predicts HFNC failure
• Have NIV/intubation equipment available at bedside

9. Psychological and Rehabilitative Care

• ICU delirium assessment (CAM-ICU) every shift
• Encourage early mobilization as patient stabilizes (sitting, passive/active range of motion)
• Reorientation and familiarization to environment
• Family communication and psychosocial support
• Post-ICU rehabilitation planning (physical and cognitive sequelae are significant)
