Question: Are the short-term outcomes of minimally invasive surfactant therapy (MIST) relatively superior to those of INtubation, SURfactant administration, and Extubation (INSURE) in preterm infants with respiratory distress syndrome (RDS)? Finding: MIST could be an appropriate substitution for INSURE in preterm infants with RDS since it reduced hospitalization time and number of side effects. Meaning: MIST is recommended for surfactant administration for its proven advantages over the INSURE technique. |
Following the first successful trial of surfactant replacement therapy for preterm infants with respiratory distress syndrome (RDS) by Fujiwara in 1980, several animal-derived natural surfactants and synthetic surfactants have been developed. Synthetic surfactants were designed to overcome limitations of natural surfactants such as cost, immune reactions, and infections elicited by animal proteins contained in natural surfactants. However, first-generation synthetic surfactants... |

To date, preterm infants with respiratory distress syndrome (RDS) after birth have been managed with a combination of endotracheal intubation, surfactant instillation, and mechanical ventilation. It is now recognized that noninvasive ventilation (NIV) such as nasal continuous positive airway pressure (CPAP) in preterm infants is a reasonable alternative to elective intubation after birth. Recently, a meta-analysis of large controlled trials... |
Respiratory distress syndrome (RDS) among preterm infants is typically due to a quantitative deficiency of pulmonary surfactant. Aside from the degree of prematurity, diverse environmental and genetic factors can affect the development of RDS. The variance of the risk of RDS in various races/ethnicities or monozygotic/dizygotic twins has suggested genetic influences on this disorder. So far, several specific mutations in... |
Purpose:In contrast with traditional time-cycled, pressure-limited ventilation, during volume-controlled ventilation, a nearly constant tidal volume is delivered with reducing volutrauma and the episodes of hypoxemia. The aim of this study was to compare the efficacy of pressure-regulated, volume controlled ventilation (PRVC) to Synchronized intermittent mandatory ventilation (SIMV) in VLBW infants with respiratory distress syndrome (RDS). Methods : 34 very low birth... |
Transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), and persistent pulmonary hypertension (PPHN) are the three most common disorders that cause respiratory distress after birth. An understanding of the pathophysiology of these disorders and the development of effective therapeutic strategies is required to control these conditions. Here, we review recent papers on the pathogenesis and treatment of neonatal... |

Purpose : Indomethacin is widely used for the prophylaxis and treatment of patent ductus arteriosus (PDA); however, it is associated with side effects such as renal failure, intraventricular hemorrhage, and gastrointestinal bleeding. Intravenous ibuprofen has been shown to be as effective as indomethacin in prompting PDA closure. If treatment with oral ibuprofen is as effective as indomethacin, it would have... |
H-type tracheoesophageal fistula (TEF) is extremely rare in infants and children, and clinical manifestations of this condition are diverse based on its severity. Some cases of congenital TEF diagnosed in adulthood have been reported, which indicate the difficulty of early diagnosis of this disease. Gastroesophageal reflux (GER) may induce chronic aspiration, pulmonary aspiration, apparent life-threatening events, and failure to thrive.... |

The major pathogenesis of acute respiratory distress syndrome (ARDS) is an inflammatory process that results from a diversity of injuries to the body. Due to the various cytokines and vasoactive peptides released from the endothelium, the vascular permeability is increased; the migration of inflammatory cells and the leakage of plasma proteins then occur and edema develops in the alveolus. There... |

Purpose : Surfactant replacement therapy in neonates with respiratory distress syndrome(RDS) has been used in Korea since 1990. We undertook a collective study of trials from multi-hospitals to evaluate results of neonates with RDS who were treated with surfactant during the past 15 years in Korea(Period I, P-I, 1990-91; Period II, P-II, 1996; Period-III, P-III; 2002). Methods : There were 60... |

Both low levels of surfactant protein A(SP-A) and SP-A alleles have been associated with RDS. However, the genes underlying susceptibility to RDS are insufficiently known. The candidate-gene approach was used to study the association between the SP-A gene locus and RDS in... |
