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.

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.

Renal insufficiency in children born preterm: examining the role of neonatal acute kidney injury.

OBJECTIVE: To identify the prevalence of renal insufficiency (RI) in children with a history of prematurity and acute kidney injury (AKI). STUDY DESIGN: This prospective cohort study evaluated renal function in children born preterm at 5-9 years of age. Univariable analyses compared perinatal and follow-up data from subjects with and without AKI history, and with and without current RI. Regression analyses were attempted to model RI as a function of AKI and other clinical risk factors. RESULTS: Fifteen of 43 (35%) participants had previously undiagnosed RI. Only children with no AKI history or neonatal stage 1 AKI presented for follow-up. Children born preterm with a history of stage 1 AKI had higher serum creatinine (sCr) at follow-up, but were not more likely to have RI compared to children without stage 1 AKI history (RI prevalence 30% and 36% in AKI and non-AKI group, respectively). CONCLUSION: The high prevalence of RI in this preterm cohort at middle childhood follow-up highlights the need for routine kidney health assessments in this population. Large multicenter studies are needed to further characterize the impact of premature birth and mild AKI on renal function throughout childhood.
