Summary Pulmonary surfactant is a complex mixture of specific lipids, proteins and carbohydrates, which is produced in the lungs by type II alveolar epithelial cells. The mixture is surface active and acts to decrease surface tension at the air-liquid interface of the alveoli. The presence of such molecules with surface activity had been suspected since the early 1900s and was finally.

BACKGROUND In the 1960s and 1970s, pulmonary haemorrhage (PH) occurred mainly in full-term infants with pre-existing illness with an incidence of 1.3 per 1000 live births. Risk factors for PH included severity of illness, intrauterine growth restriction, patent ductus arteriosus (PDA), coagulopathy and the need for assisted ventilation in pulmonary surfactant production causes Respiratory Distress Syndrome (RDS). Risk factors associated with RDS are shown in Table 1, and incidence of RDS at RPA 1992-8 in Figure 1. Exogenous surfactant has been shown to reduce neonatal mortality, death or bronchopulmonary dysplasia (BPD) and airleaks 1, 2. The principle of administration is to.
The increase in surface tension can be overcome by increasing the concentration of surfactant and this is the rationale for the use of surfactant in pulmonary haemorrhage. In a retrospective survey, administration of exogenous surfactant was a useful adjunctive therapy in neonates with clinically significant pulmonary haemorrhage
AIM To determine if pulmonary haemorrhage after surfactant treatment increases short and long term morbidity and mortality in neonates weighing <1500 g at birth. METHODS Neonates weighing <1500 g at birth who developed pulmonary haemorrhage after surfactant treatment were identified from a database. Based on the change in FIO2, pulmonary haemorrhage was classified as mild, moderate, or severe surfactant in pulmonary hemorrhage in neonates, suggesting the need for such trials. Recent Developments A recent study evaluated the impact of surfactant upon in-vitro clot formation in order to assess the role of surfactant in the pathogenesis of pulmonary haemorrhage.

1 Introduction. Acute idiopathic pulmonary hemorrhage (AIPH) in infants is a rare cause of diffuse alveolar hemorrhage. It has sudden onset, causes severe acute respiratory distress in previously healthy infants, and is potentially fatal, suggesting that it may be a cause of sudden infant death syndrome. AIPH is a diagnosis of exclusion, and its diagnosis can be difficult because pediatric. . Secondary surfactant deficiency complicates other respiratory disorders in neonates such as meconium aspiration syndrome, sepsis/pneumonia, congenital lung malformations and possibly pulmonary haemorrhage.

Pulmonary hemorrhage (PH) is an acute, catastrophic event characterized by discharge of bloody fluid from the upper respiratory tract or the endotracheal tube. The hematocrit of the hemorrhagic fluid is often 15 to 20 percentage points below the venous hematocrit. The incidence of PH is 1 to 12 per 1,000 live births Respiratory distress syndrome is caused by pulmonary surfactant deficiency in the lungs of neonates, most commonly in those born at < 37 weeks gestation. Risk increases with degree of prematurity. Symptoms and signs include grunting respirations, use of accessory muscles, and nasal flaring appearing soon after birth The question of whether and how infants should be sedated for MIST remains uncertain, and future techniques for truly non-invasive surfactant administration may negate the need for sedation entirely. Further research is underway to help guide clinicians in balancing infant comfort and maximising outcomes for preterm infants requiring surfactant Less approved recommendation for use of exogenous surfactant therapy includes intubated newborn infants with pulmonary haemorrhage which leads to clinical deterioration. 6. Finally, for lung hypoplasia and congenital diaphragmatic hernia for which only small case series have been reported and no conclusions can be made Exogenous surfactant is now an established treatment for respiratory distress syndrome (RDS). It seems to be safe and eVective for the management of RDS and significantly reduces morbidity and mortality. 1 The risk of pulmonary haemorrhage, however, seems to be increased in premature neonates with RDS who are treated with surfactant. 2 There is little reported information on the clinical.
Table 1 describes the biochemical and pharmaceutical features of all animal-derived surfactants currently available to treat RDS in preterm neonates. There is a wide variation in phospholipid profile amongst surfactants. Surfactant-protein content is also variable and poractant-α is the preparation with the highest protein concentrations (especially of surfactant protein-B) surfactant has been used as adjuvant therapy in PH. Administration of curosurf in neonates presenting with pulmonary haemorrhage may result in improvement of respiratory function.(16-20) A Cochrane Systematic Review (21) concluded that although there was potential benefit of surfactant in the management of PH, ther Gunkel HJ, Banks PLC (1993) Surfactant therapy and intracranial hemorrhage: review of the literature and results of new analyses.

1. INTRODUCTION. Preterm infants (especially gestational age from 28 0/7 to 32 6/7 weeks) account for a large proportion of inpatients in neonatal intensive care unit. These infants are more likely to develop respiratory distress syndrome (RDS), and often need surfactant treatment and mechanical ventilation compared with term newborns. But, it has been proven that traditional invasive. PRIOR TO 1990, neonatal pulmonary hemorrhage occurred mainly as a terminal event among infants who were small for gestational age and asphyxiated; however, after the introduction of surfactant therapy, an increased occurrence of pulmonary hemorrhage was noted among preterm infants with respiratory distress syndrome. 1-5 Depending on birth weight and the criteria used for defining pulmonary. and bradycardia, pulmonary hemorrhage ,patent duteousarteriosus (PDA) (4),but surfactant cause decrease incidence of pneumothorax and mortality in preterm infants.(5) . This research was done to response whethe bolus surfactant administration and the use of high frequency oscillation in a premature infant.

Pulmonary hemorrhage is a life threatenin
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: The primary objective is to evaluate the effectiveness of surfactant to reduce mortality in neonates with hemorrhagic pulmonary edema and/or PH, compared to placebo or no intervention morbidity and mortality in premature infants.2 Surfactant is also effective in treating infants with meconium aspira-tion syndrome (MAS), pulmonary hemorrhage,7 and pneu-monia, although the evidence base for their use in these disease processes is much weaker than the primary indi-cation of RDS.8,9 Surfactant reduces surface tension, im Pulmonary hemorrhage in the newborn is an ominous condition that has a high neonatal mortality rate.

Abstract. Pulmonary disease is the most important cause of morbidity in preterm neonates, whose lungs are often physiologically and morphologically immature. Surfactant deficiency in immature lungs triggers a cascade of alveolar instability and collapse, capillary leak edema, and hyaline membrane formation Pulmonary surfactant is a mixture of phospholipids produced by type 2 alveolar pneumocytes from around week 36 of gestational age. The primary function of surfactant is to lower surface tension in the alveolar air-liquid interface which helps to stabilise the expanded alveolus at the end of inspiration, prevent collapse at the end of.
The use of BLES® in infants less than 380 g or greater than 4460 g birth weight has not been evaluated in controlled trials. CONTRAINDICATIONS Use of BLES (bovine lipid extract surfactant) is contraindicated in infants with active pulmonary haemorrhage Without surfactant, pulmonary airways become unstable and have decreased compliance. Surfactant decreases the surface tension of the alveoli in order to aid the diffusion of gases (Martini 1998). A reduction in production of surfactant will directly affect gas exchange. General causes of reduced surfactant production are
The evidence for treating RDS with surfactant is strong. 10 For best effect, especially among extremely preterm infants, 3,4 a policy of early rescue surfactant is advocated. 10,24 Our findings of significantly lower neonatal morbidity in infants treated with surfactant within 2 hours after birth and of increased mortality in infants in which. Pulmonary hemorrhage usually attack 7 out of 10% of autopsies in newborns in which about 80% autopsies have been seen very much in preterm infants. In an extreme condition, pulmonary hemorrhage is found to be combined with bleeding from different sites of the body which involves about one-third of the lung and this condition is highly mortal Surfactant treatment has become the standard of care in premature infants with respiratory distress syndrome (RDS). Pulmonary hemorrhage, pulmonary edema, pneumonia, and atelectasis have been. Surfactant 1. Surfactant Dr Varsha Atul Shah 2. Introduction The lungs of preterm infants lack adequate pulmonary surfactant, a constituent of the air- liquid interface, that normally lines the alveolar surfaces and terminal airways. RDS is due to surfactant deficiency, which increases the surface tension at the air-liquid interface of the terminal respiratory units. T

Thirty-three percent (5/15) of the infants with PH died within 14 days of the hemorrhage. Of the 15 PH, 73% occurred within 48 hours of the first surfactant dose. Pulmonary hemorrhage was more common in male infants and infants of mothers who received antibiotic therapy during labor (P < or = .04) Iran Infants Preterm Birth Pulmonary Disorders 1. Background Respiratory distress syndrome (RDS) is the leading cause of neonatal mortality and morbidity, and it is mainly diagnosed with the help of clinical features and chest radiograph ().Gestational age is the major risk factor, as 90% - 95% of the neonates aged between 22 - 24 week, 5% of those aged more than 34 week, and 1% of those aged.
CUROSURF is the only exogenous surfactant to undergo a liquid-gel chromatography purification step during manufacturing 1-5. Liquid-gel chromatography allows CUROSURF to maintain a much higher concentration of polar lipids vs other exogenous surfactants 1,3,5,6. *Based on 1000-gram infant and manufacturer's dosing schedule In the neonate, the factors most commonly associated with hemorrhagic pulmonary edema are those that increase pulmonary blood flow, such as a left-to-right shunt or treatment with surfactants. 35, 37 Clinical features that increase the risk of hemorrhagic pulmonary edema or even frank pulmonary hemorrhage in neonates include extreme preterm. Objective To study the clinical features and prognosis of meconium aspiration syndrome (MAS) complicated by neonatal pulmonary hemorrhage (NPH) in neonates. Methods A retrospective analysis was performed for the clinical data of 45 neonates with MAS complicated by NPH who were admitted to the hospital from December 2015 to December 2018. a Data are missing for 19 infants in the usual care group; the percentage shown is based on n = 208.. Primary outcome: The need for endotracheal intubation and surfactant instillation within the first 4 days of life was significantly reduced in infants in the aerosol group upon intent-to-treat analysis (26% vs. 50%; RR 0.51, 90% CI 0.41 - 0.63, p < 0.0001) (table 2), with a number needed to.
Pulmonary Hemorrhage. DEFINITION: Pulmonary hemorrhage (P-Hem) is an acute, catastrophic event characterized by discharge of bloody fluid from the upper respiratory tract or the endotracheal tube. The incidence of P-Hem is 1 in 1,000 live births. P-Hem is present in 7 to 10% of neonatal autopsies, but up to 80% of autopsies of very preterm infants Intubated newborn infants with pulmonary hemorrhage which leads to clinical deterioration should receive exogenous surfactant therapy as one aspect of clinical care (grade C). Finally, for lung hypoplasia and congenital diaphragmatic hernia, only small case series have been reported  ,  and no conclusions can be made
Surfactant administration in NICU. Date last published: 25 March 2020. The administration of exogenous surfactant to newborn infants with or at risk of Respiratory Distress Syndrome (RDS) is established practice. Infants with RDS who are treated with early surfactant and CPAP are less likely to need mechanical ventilation B. Complications from administration of surfactant include: Desaturations, transient bradycardia, pneumothorax or air leak, endotracheal tube (ETT) obstruction, and increase risk of pulmonary hemorrhage. C. Dosing for Beractant is 4mls/kg per the endotracheal tube every 6 hours for a maximum of four doses
Late preterm (LPT) neonates are at a high risk for respiratory distress soon after birth due to respiratory distress syndrome (RDS), transient tachypnea of the newborn, persistent pulmonary hypertension, and pneumonia along with an increased need for surfactant replacement therapy, continuous positive airwa Rationale: Bronchopulmonary dysplasia (BPD) is an important complication of mechanical ventilation in preterm infants, and no definite therapy can eliminate this complication. Pulmonary inflammation plays a crucial role in its pathogenesis, and glucocorticoid is one potential therapy to prevent BPD. Objectives: To compare the effect of intratracheal administration of surfactant/budesonide with. about the efficacy and safety of surfactant therapy for treatment of preterm infants provided the rationale for planning and conduction of the current study. Aim of the study: To compare the outcome of preterm infants with RDS receiving surfactant therapy with group of preterm infants having RDS but did not receive surfactant therapy pulmonary vascular resistance, promotes left-to-right shunting through ductusarteriosus van HoutenJ, et al. Pulmonary hemorrhage in premature infants after treatment with synthetic surfactant: an autopsy evaluation. J Pediatr199 This means that you cannot use the pulmonary graphics to determine whether the PEEP is optimal or if the baby is ready to wean. A better way to determine whether the surfactant has had an effect is simply to watch the FiO2; as the figure in Ben Stenson's article referenced above shows, the decrease in FiO2 occurs at the same time as the improvement in Static Compliance Surfactant deficiency is associated with onset of respiratory distress syndrome (RDS), a major cause of morbidity and mortality in premature infants. 2 Surfactant is also effective in treating infants with meconium aspiration syndrome (MAS), pulmonary hemorrhage, 7 and pneumonia, although the evidence base for their use in these disease.
