Alternative routes of surfactant application - An update.

Non-invasive modes of respiratory support have been shown to be the preferable way of primary respiratory support of preterm infants with respiratory distress syndrome (RDS). The avoidance of invasive mechanical ventilation can be beneficial for preterm infants in reduction of morbidity and even mortality. However, it is well-established that some infants managed with non-invasive respiratory support from the outset have symptomatic RDS to a degree that warrants surfactant administration.

Surfactant delivery strategies to prevent bronchopulmonary dysplasia.

Bronchopulmonary dysplasia (BPD) is one of the most devastating morbidities of preterm infants. Antenatal factors like growth restriction and inflammation are risk factors for its development. Use of oxygen and positive pressure ventilation, which are often necessary to treat respiratory distress syndrome (RDS), increase the risk for development of BPD.

Implementation of Surfactant Administration through Laryngeal or Supraglottic Airways (SALSA): A Jordanian NICU's Journey to Improve Surfactant Administration.

Administration of liquid surfactant through an endotracheal tube for the treatment of respiratory distress syndrome has been the standard of care for decades. Surfactant administration through laryngeal or supraglottic airways (SALSA) is a simplified procedure for delivery of surfactant that is less invasive and better tolerated. The Al Bashir Maternity and Children’s Hospital NICU in Amman, Jordan, implemented SALSA as a potentially better practice in 2019 with the objective to effectively and efficiently deliver surfactant in a minimally invasive way and to decrease the adverse events associated with intubation−surfactant−extubation (InSurE) and laryngoscopy.

Surfactant Administration Through Laryngeal or Supraglottic Airways (SALSA): A Viable Method for Low-Income and Middle-Income Countries.

Administration of liquid surfactant through an endotracheal tube for the treatment of respiratory distress syndrome has been the standard of care for decades. A skilled health care provider is needed to perform this procedure. In lower-income and middle-income countries (LMICs), healthcare resources are often limited, leading to increased mortality of premature infants, many of whom would benefit from surfactant administration.

Alternative Methods of Surfactant Administration in Preterm Infants with Respiratory Distress Syndrome: State of the Art.

For preterm infants with respiratory distress syndrome, delivery of surfactant via brief intubation (INtubate, SURfactant, Extubate; InSurE) has been the standard technique of surfactant administration. However, this method requires intubation and positive pressure ventilation. It is thought that even the short exposure to positive pressure inflations may be enough to initiate the cascade of events that lead to lung injury in the smallest neonates.

Surfactant Administration Through Laryngeal or Supraglottic Airways.

Noninvasive ventilation is frequently used in the treatment of infants with respiratory distress syndrome. This practice is often effective in higher gestational age neonates, but can be difficult in those with lower gestational ages as surfactant deficiency can be severe. While noninvasive ventilation avoids the negative effects of intubation and ventilator-induced lung injury, failure of this mode of support does occur with relative frequency and is primarily caused by the poorly compliant, surfactant-deficient lung.

A systematic review of surfactant delivery via laryngeal mask airway, pharyngeal instillation, and aerosolization: Methods, limitations, and outcomes.

Less invasive surfactant administration methods without laryngoscopy and endotracheal catheterization include delivery via laryngeal mask airway, pharyngeal instillation, and aerosolization. These less invasive techniques are promising and have several advantages over INSURE (Intubation-Surfactant-Extubation) and thin catheter techniques. The objective of this review is to discuss the requisites, techniques, short-term outcomes, and adverse events associated with these methods.

Partial gonadal dysgenesis associated with a pathogenic variant of transcription factor.

A term neonate was admitted to the Neonatal Intensive Care Unit for respiratory distress, hypotonia and atypical genitalia. Significant findings included a small phallic structure, labial folds, no palpable gonads and two perineal openings. Pelvic ultrasound showed uterine didelphys and a gonad in the right inguinal canal.

Laryngeal Mask Airway for Surfactant Administration in Neonates: A Randomized, Controlled Trial.

Objective: To determine if preterm infants with moderate respiratory distress syndrome on continuous positive airway pressure (CPAP) who received surfactant via a laryngeal mask airway (LMA) would have a decreased rate of intubation and mechanical ventilation compared with those on CPAP who did not receive surfactant.

Study Design: In this prospective, multicenter, randomized controlled trial, 103 premature infants 28-35 weeks gestation, ≥1250 g and ≤36 hours old on CPAP requiring fraction of inspired oxygen 0.30-0.

Mesenchymal stem cells in the pathogenesis and treatment of bronchopulmonary dysplasia: a clinical review.

Advances in neonatal medicine have led to increased survival of infants born at the limits of viability, resulting in an increased incidence of bronchopulmonary dysplasia (BPD). BPD is a chronic lung disease of premature infants characterized by the arrest of alveolarization, fibroblast activation, and inflammation. BPD leads to significant morbidity and mortality in the neonatal period and is one of the leading causes of chronic lung disease in children.

Current practice of neonatal resuscitation documentation in North America: a multi-center retrospective chart review.

Background: To determine the comprehensiveness of neonatal resuscitation documentation and to determine the association of various patient, provider and institutional factors with completeness of neonatal documentation.

Methods: Multi-center retrospective chart review of a sequential sample of very low birth weight infants born in 2013. The description of resuscitation in each infant's record was evaluated for the presence of 29 Resuscitation Data Items and assigned a Number of items documented per record.

Four-year follow-up of megalencephaly, polymicrogyria, postaxial polydactyly and hydrocephalus (MPPH) syndrome.

A male infant was born by emergent caesarean section at 39 weeks gestational age secondary to maternal and fetal distress. Initial physical examination was notable for macrocephaly (greater than+2SD), postaxial polydactyly of the hands and facial dysmorphism. Head imaging demonstrated diffuse polymicrogyria without hydrocephalus.

Laryngeal mask airway for surfactant administration in a newborn animal model.

Premature infants are subjected to adverse effects of intubation to benefit from surfactant. We hypothesized that administration of surfactant through a laryngeal mask airway (LMA) is as effective as administration through an endotracheal tube (ETT) and that time and physiologic changes during instrumentation will be less in the LMA group. This study is a randomized, controlled trial using newborn pigs.

Improved gas exchange and survival after KL-4 surfactant in newborn pigs with severe acute lung injury.

Objective: To determine the effectiveness of artificial surfactant therapy using KL-4 surfactant in newborn pigs with hydrochloric acid (HCl)-induced acute lung injury (ALI).

Design: After induction of ALI via intratracheal HCl instillation, pigs were randomized to receive 5.8 ml/kg KL-4 surfactant or no surfactant prior to extubation to bubble CPAP.

Diabetic ketoacidosis, respiratory distress and myocardial dysfunction.

This case report describes a patient with respiratory distress, myocardial dysfunction, elevated troponin level, ECG changes and pulmonary oedema secondary to new onset diabetic ketoacidosis (DKA). This case may be unique, but it is possible that less severe cases occur and are underappreciated in the paediatric setting. This report demonstrates the need to closely evaluate and monitor cardiac function in patients with DKA.

Premedication for nonemergent neonatal intubations: a randomized, controlled trial comparing atropine and fentanyl to atropine, fentanyl, and mivacurium.

Objective: The purpose of this work was to investigate whether using a muscle relaxant would improve intubation conditions in infants, thereby decreasing the incidence and duration of hypoxia and time and number of attempts needed to successfully complete the intubation procedure.

Patients/methods: This was a prospective, randomized, controlled, 2-center trial. Infants requiring nonemergent intubation were randomly assigned to receive atropine and fentanyl or atropine, fentanyl, and mivacurium before intubation.
