Video laryngoscopy-assisted less-invasive surfactant administration quality improvement initiative.

OBJECTIVE: To describe the use of quality improvement methodology in transitioning from delivery of surfactant by INSURE (INtubation-SURfactant administration-Extubation) to video laryngoscope-assisted LISA (less-invasive surfactant administration) for infants with respiratory distress syndrome (RDS) receiving non-invasive ventilatory support. SETTING: Two large neonatal intensive care units (NICUs) at Northwell Health (New Hyde Park, New York, USA). STUDY POPULATION: Infants with RDS receiving continuous positive airway pressure in the NICU and eligible for surfactant administration. RESULTS: LISA was initiated in our NICUs in January 2021, after extensive guideline development, education programmes, hands-on training and provider credentialing. Our Specific, Measurable, Achievable, Relevant and Timely aim was to deliver surfactant by LISA for 65% of total doses by 31 December 2021. This goal was achieved within 1 month of go-live. In total, 115 infants received at least one dose of surfactant during the year. Of those, 79 (69%) received it via LISA and 36 (31%) via INSURE. Two Plan-Do-Study-Act cycles contributed to improved adherence to guidelines on timely surfactant administration and both written and video documentation. CONCLUSIONS: Safe and effective introduction of LISA with the use of video laryngoscopy is achievable with careful planning, clear clinical guidelines, adequate hands-on training and comprehensive safety and quality control.

Congenital and Perinatal Varicella Infections.

Varicella-zoster virus (VZV) is a human pathogen of the α-herpesvirus family. Some fetuses infected in utero around 8-20 weeks of pregnancy show signs of congenital varicella syndrome (CVS). Infants born to mothers who develop varicella within 5 days before and 2 days after delivery can experience severe disease with increased mortality. The best diagnostic modality is polymerase chain reaction (PCR), which can be done using vesicular swabs or scrapings, scabs from crusted lesions, tissue from biopsy samples, and cerebrospinal fluid. The prevention and management of varicella infections include vaccination, anti-VZV immunoglobulin, and specific antiviral drugs. In this article, we have reviewed the characteristics of VZV, clinical manifestations, management of perinatal infections, and short- and long-term prognosis.

Enteroviral Infections in Infants.

Enteroviruses (EVs) are major pathogens in young infants. These viruses were traditionally classified into the following four subgenera: polio, coxsackie A and B, and echoviruses. Now that poliomyelitis seems to be controlled in most parts of the world, coxsackie and echoviruses are gaining more attention because (i) the structural and pathophysiological similarities and (ii) the consequent possibilities in translational medicine. Enteroviruses are transmitted mainly by oral and fecal-oral routes; the clinical manifestations include a viral prodrome including fever, feeding intolerance, and lethargy, which may be followed by exanthema; aseptic meningitis and encephalitis; pleurodynia; myopericarditis; and multi-system organ failure. Laboratory diagnosis is largely based on reverse transcriptase-polymerase chain reaction, cell culture, and serology. Prevention and treatment can be achieved using vaccination, and administration of immunoglobulins and antiviral drugs. In this article, we have reviewed the properties of these viruses, their clinical manifestations, and currently available methods of detection, treatment, and prognosis.

Lung ultrasound assessment of pulmonary edema in neonates with chronic lung disease before and after diuretic therapy.

INTRODUCTION: Bronchopulmonary dysplasia (BPD) is characterized by lung injury with varying degrees of disrupted alveolarization, vascular remodeling, inflammatory cell proliferation, and pulmonary edema. Diuretics are often used to ameliorate the symptoms or progression of BPD. Our primary objective was to use lung ultrasound (LUS) to determine if diuretics decrease pulmonary edema in infants with BPD. The secondary objective was to assess changes in respiratory support during the first week after initiation of diuretics. METHODS: Premature infants requiring noninvasive respiratory support and starting diuretic therapy for evolving BPD were compared with a similar group of infants not receiving diuretics (control). For the diuretic group, LUS exams were performed before and on Days 1, 3, and 6 after initiation of treatment. For the control group, LUS was performed at equivalent time points. A composite pulmonary edema severity (PES) score of 0-5 was calculated based on the total number of B-lines in six scanned areas. Respiratory support parameters (FiO2 , nasal cannula flow, or CPAP) were also recorded. RESULTS: Infants in the diuretic (n = 28) and control (n = 23) groups were recruited at median corrected gestational ages of 34.2 (33.3-35.9) and 34.0 (33.4-36.3) weeks, respectively (p = 0.82). PES scores, FiO2 , and respiratory flow support decreased significantly from Days 0 to 6 (p < 0.0001, p = 0.001, and p = 0.01, respectively) in the diuretic group, but not in the control group. CONCLUSION: Diuretic use is associated with decreased pulmonary edema and improved oxygenation in infants with BPD during the first week of treatment.

Idiopathic infantile arterial calcification: a case report of successful extracorporeal membrane oxygenation support.

Idiopathic infantile arterial calcification is a rare cause of infantile ischemic cardiac failure with extremely poor prognosis. We present the first case report of successful extracorporeal membrane oxygenation support and outcome in a child with idiopathic infantile arterial calcification (IIAC). This 6-week-old infant presented with cardiogenic shock and circulatory collapse. The patient underwent extracorporeal cardiopulmonary resuscitation, allowing stabilization, diagnosis, and treatment with etidronate, followed by successful discharge to home.
