ClassificationTherapeutic: anti rds agents
Pharmacologic: pulmonary surfactants
Prevention of Respiratory Distress Syndrome (RDS) in premature infants who are at high risk. Not indicated for (Adult Respiratory Distress Syndrome) ARDS.
Provides replacement pulmonary surfactant; lowers surface tension which stabilizes alveoli from collapse.
↓ incidence of RDS at 24 hr with decreased associated mortality.
Absorption: Action is local following intratracheal administration.
Metabolism and Excretion: Unknown.
Time/action profile (effects on surface tension)
|Intratracheal||unknown||unknown||up to 6 hr|
Contraindicated in: None noted.
Use Cautiously in: Frequent assessment is necessary; modifications in oxygen/ventilatory support may be required.
Adverse Reactions/Side Effects
- oxygen desaturation
- reflux into endotracheal tube/endotracheal tube obstruction
Drug-Drug interactionNone noted.
Intratracheal (Neonates) 5.8 mL/kg birth weight may be repeated no more frequently than every 6 hr, not to exceed 4 doses in the first 48 hr of life.
Intratracheal suspension (contains phospholipids): 8.5 mL/vial
- Monitor respiratory status (lung sounds, oxygen saturation) frequently during therapy.
- Assess for adverse reactions (bradycardia, oxygen desaturation, reflux of drug into entotracheal tube, airway/endotracheal tube obstruction) frequently during treatment. If these occur, interrupt therapy and assess clinical condition. Suctioning or reintubation may be required. Continue treatment once infant is stable.
Potential Nursing DiagnosesIneffective breathing pattern (Indications)
Ineffective airway clearance (Adverse Reactions)
- Intratracheal: Should be administered by clinicians experienced in intubation, ventilator management, and care of premature infants.
- Up to 4 doses can be administered within the first 48 hrs of life; give no more frequently than every 6 hrs.
- Warm vial for 15 min in preheated dry block heater set at 44°. After warming, shake vial vigorously until suspension is uniform and free-flowing. Solution should ve opaque white to off-white. Record date and time warmed in space provided on carton. May be stored for up to 2 hrs after warming at room temperature; do not return to refrigerator. Discard is not used within 2 hrs. Vials are single-use.
- Slowly draw up appropriate amount of lucinactant using a 16 or 18 gauge needle.
- Assure patency and proper placement of endotracheal tube; may be suctioned before administration. Allow infant to stabilize before administering. Position infant in right lateral decubitus position with head and thorax inclined upward 30°. Attach syringe containing lucinactant to a 5–French end-hole catheter. Thread catheter through a Bodai valve or equivalent device that allows maintenance of positive end-expiratory pressure, then advance tip of catheter into endotracheal tube. Position catheter such that tip is slightly distal to end of endotracheal tube.
- Each dose is delivered in 4 aliquots. Instill first aliquot (1/4 of total volume) as a bolus while continuing positive pressure mechanical ventilation and maintaining positive end-expiratory pressure of 4 or 5 cm H2O. Adjust ventilator settings to maintain appropriate oxygenation and ventilation. Once infant is stable and oxygen saturation is at least 90% and heart rate is >120 beats per min, repeat procedure with infant in left lateral decubitus position. Repeat procedure with infant in right then left decubitus position for 4 aliquots. Evaluate infant's respiratory status between aliquots.
- After instillation of last aliquot, remove catheter and resume ventilation. Keep infant's head elevated at least 10° for at least 1–2 hr. Do not suction infant during first hr after dosing unless signs of significant airway obstruction occur.
- Explain purpose of therapy to parents.
- Decrease in signs of RDS.
