Respiratory distress syndrome RDS is defined as respiratory difficulty starting shortly after birth commonly in a preterm newborn and is due to deficiency of pulmonary surfactant. It occurs in 15-30 of those between 32 and 36 weeks of gestational age in about 5 beyond 37 weeks and rarely at term.

Why is surfactant so important.
. Babies born without enough surfactant are said to have respiratory distress syndrome or RDS. In this regard why is surfactant important for a baby. Surfactant is a liquid made by the lungs that keeps the airways alveoli open.
Natural surfactant is associated with greater early. IncreaseRDS riskDecreaseRDS risk Decreasing gestational age3. Surfactant has revolutionized the treatment of respiratory distress syndrome and some other respiratory conditions that affect the fragile neonatal lung.
Pulmonary surfactant is used as a medication to treat and prevent respiratory distress syndrome in newborn babies. RDS in a premature infant is defined as respiratory distress requiring more than 30 oxygen delivered by positive pressure using either Nasal CPAP or an ET Tube with a chest radiograph that has diffuse infiltrates with a ground. Surfactant treatment improves oxygenation and reduces the need for ECMO without an increase in morbidity in neonates with meconium aspiration syndrome LOE 2.
Surfactant coats the alveoli the air sacs in the lungs where oxygen enters the body. This prevents the alveoli from sticking together when your baby exhales breathes out. If a baby is premature born before 37 weeks of pregnancy they may not have made enough surfactant yet.
Surfactant is necessary for breathing. Author Alan H Jobe 1. Surfactant replacement therapy for RDS - Early rescue therapy should be practiced.
Prevention is generally done in babies born at a gestational age of less than 32 weeks. Low amounts of surfactant lead to poor lung function. As the alveoli collapse damaged cells collect in the airways.
Why do premature babies need surfactant. While respiratory distress syndrome usually affects premature infants in rare cases the syndrome can also affect full-term infants. Without enough surfactant the lungs collapse and the newborn has to work hard to breathe.
Infant Premature Respiratory Distress Syndrome Surface-Active Agents. Preterm infants with respiratory distress syndrome RDS requiring surfactant therapy have been traditionally receiving surfactant by intubation surfactant and extubation technique InSurE which comprises of tracheal intubation. Surfactant replacement therapy for premature babies acts to keep the alveoli from sticking together and is supplemented with oxygen or ventilation to help the baby breathe.
Premature infants may be born before their lungs make enough surfactant. Deficiency of pulmonary surfactant leads. Surfactant treatment reduces the risk and the severity of respiratory distress syndrome RDS in premature infants.
The majority of premature babies recover from RDS without major complications while others are at risk for chronic breathing difficulties. The lungs of premature infants however have not developed enough alveoli or Type II alveolar cells to produce the amount of surfactant needed to breathe properly. When there is not enough surfactant the tiny alveoli collapse with each breath.
When premature lungs are treated with surfactant after birth the infants blood oxygen levels usually improve within minutes. Despite its widespread use the optimal method of surfactant administration in preterm infants has yet to be clearly determined. Discard excess surfactant through the catheter so that only the dose to be given remains in the syringe.
The open study of infants at high risk of or with respiratory insufficiency the role of surfactant osiris 52 demonstrated that the combined incidence of death or bpd was reduced by about 11 when surfactant was given at a mean postnatal age of 2 h rather than 3 h rr089 95 ci 079 to 100 evidence level 1b showing that even fairly. First dose needs to be given as soon as diagnosis of RDS is made.

Surfactant also helps treat RDS. The clinical applications of. Surfactant is a foamy substance that keeps the lungs fully expanded so that newborns can breathe in air once they are born.
Surfactants were first approved by the Food and Drug Administration FDA in 1990 and also became standard of care for treating respiratory distress syndrome RDS. RDS is more common in premature newborns because their lungs are not able to make enough surfactant. The principle of administration is to deliver surfactant as early as possible to those infants with a high probability of surfactant deficiency.
It also reduces the overall risk of death. Thus preterm infants who are born with immature lungs and are surfactant deficient develop respiratory distress syndrome after being born. Surfactant a medication used to treat respiratory distress syndrome Fine-mist aerosolized or IV medication to strengthen breathing and heart rate.
Surfactant replacement has not been shown to affect the incidence of neurologic developmental behavioral medical or educational outcomes in preterm infants LOE 2. Why do we give babies surfactant. The surfactant mixture is an essential group of molecules to support air breathing.
Why when and how to give surfactant Pediatr Res. Attach the pre-cut 5 Fr catheter to the syringe prime or fill the catheter with surfactant to the end. Exogenous surfactant has been shown to reduce neonatal mortality death or bronchopulmonary dysplasia BPD and airleaks 1 2.
Slowly withdraw a little over the required dose into a 3 or 5 mL plastic syringe using a large-gauge needle. This liquid makes it possible for babies to breathe in air after delivery. This liquid makes it possible for babies to breathe in air after delivery.
Surfactant is a liquid made by the lungs that keeps the airways alveoli open. Medications may be given to your baby to promote maturing and to stimulate normal functioning of the lungs heart and circulation. This prevents the alveoli from sticking together when your baby exhales breathes out.
Pulmonary surfactant is used as a medication to treat and prevent respiratory distress syndrome in newborn babies.
