Ultrasound-guided vascular access in the neonatal intensive care unit: a nationwide survey.

Ultrasound-guided vascular access (USG-VA) is recommended by international practice guidelines but information regarding its use in the neonatal intensive care unit (NICU) is lacking. Our objective was to assess neonatologist's perceptions and current implementation of USG-VA in Spain. This was a nationwide online survey. The survey was composed of 37 questions divided in 4 domains: (1) neonatologist's background, (2) NICU characteristics, (3) personal perspectives about USG-VA, and (4) clinical experience in USG-VA. One-hundred and eighty survey responses from 59 NICUs (62% of Spanish NICUs) were analyzed. Most neonatologists (81%) perceive that competence in USG-VA is indispensable or very useful in clinical practice. However, 64 (35.5%) have never used USG-VA in real patients. Among neonatologists with some experience in USG-VA most perform less than 5 procedures per year (59% in venous access and 80% in arterial access) and a 38% and 60% have never used USG for venous and arterial access, respectively, in very low birth weight infants (VLBWI). More than a half of neonatologists (55.5%) use US to check catheter tip location but a 46.6% always perform a radiography for confirmation. Spanish neonatologists report that resident/fellow training in USG-VA is absent (52.2%) or unstructured (32%) in their units. The lack of adequate training is identified by a 60% of neonatologists as the most important barrier for implementation of USG-VA and 87% would recommend that future neonatologists receive formal training. CONCLUSION: Spanish neonatologists perceive that USG-VA is important in clinical practice but currently, these techniques are largely underused. Our results indicate that specific training in USG-VA should be implemented in the NICU. WHAT IS KNOWN: • Ultrasound-guided vascular access is recommended as the preferred method for central venous access and arterial line placement in children and adults. • The degree of current implementation of ultrasound for vascular access in the NICU and the perceptions of neonatologist about its use are largely unknown. WHAT IS NEW: • Most neonatologists consider that competence in ultrasound-guided vascular access is an indispensable aid for clinical practice. • However, most neonatologists are not adequately trained in ultrasound-guided vascular access and the technique is largely underused.

Randomized Trial on Echocardiography-Guided Ductus Arteriosus Treatment to Reduce Necrotizing Enterocolitis.

OBJECTIVE: Patent ductus arteriosus (PDA) approach remains controversial. We aim to evaluate whether echocardiography-guided (EchoG) PDA closure (to reduce drug exposure) and 24-h continuous ibuprofen infusion (24 h-IB) (to reduce peak concentration), compared with EchoG PDA closure plus conventional bolus (bolus-IB), reduces severe bowel adverse event rate in preterm infants with hemodynamically significant (hs) PDA. STUDY DESIGN: The study design is a multicenter, blinded, randomized controlled trial. Infants with <28 weeks of gestation underwent routine echocardiographic assessment (18-72 h of birth); infants with 28-33 weeks were screened only in cases where PDA was clinically suspected. HsPDA was considered if ductal diameter >1.5 mm and indicators of pulmonary overflow, systemic hypoperfusion, or both were present. Pharmacodynamic effect of CYP450 genotypes was also analyzed. RESULTS: One hundred forty-six infants [median gestational age 26 (25-28) weeks; median birth weight 881 (704-1,100) g] were randomized to 24 h-IB (n = 70) or bolus-IB (n = 76) study group at 86 (58-140) h from birth. Groups were comparable regarding perinatal and neonatal clinical data, but higher prevalence of male sex in the bolus-IB group was found. Neither severe bowel adverse event rate [10% (24 h-IB) and 2.6% (bolus-IB), p = 0.1] nor ductal closure rate was different between the study groups. Postnatal age and peripheral SaO2 at treatment start and pulmonary hemorrhage were associated with severe bowel events, independent of treatment group allocation. CYP2C8 genetic polymorphisms were associated with ibuprofen efficacy (p = 0.03). CONCLUSIONS: Ibuprofen intravenous continuous infusion compared with bolus infusion in preterm infants with hsPDA shows similar rates of success and does not reduce the prevalence of severe bowel events.

Congenital cutaneous candidiasis associated with maternal peripartum candidemia.

BACKGROUND: Cutaneous congenital candidiasis (CCC) is a rare condition consisting of invasive fungal infection of the epidermis and dermis that mostly affects preterm infants. Maternal vaginal candidiasis is present in half of the cases, although the occurrence of invasive candidiasis during pregnancy or peripartum period is exceptional. CASE REPORT: We present the case of a full-term infant that was born by vacuum-assisted vaginal delivery to an apparently healthy 33 year-old woman with no history of intravenous drug use or vaginal candidiasis during pregnancy. The newborn showed a diffuse maculopapular rash with respiratory distress and bilateral interstitial lung infiltrates, requiring nasal continuous positive airway pressure support. Blood cultures obtained from the mother due to intrapartum fever yielded Candida albicans. Cultures of vaginal discharge and neonate skin also yielded C. albicans with the same in vitro susceptibly pattern. No alternative source for candidemia was identified. The clinical course after starting a systemic antifungal therapy was favorable in both the mother and the neonate, with clearance of candidemia and resolution of the skin lesions. CONCLUSIONS: CCC must be considered in full-term newborns with maculopapular rash at birth or during the first days of life. The absence of alternative sources for bloodstream infection in the present case suggests a potential etiopathogenic relationship between CCC and maternal candidemia. It is reasonable to rule out postpartum candidemia when CCC is suspected.

ANTECEDENTES: La candidiasis congénita cutánea (CCC) es una entidad infrecuente que consiste en una infección invasiva de la epidermis y dermis, fundamentalmente en neonatos pretérmino. La candidiasis vaginal materna puede estar presente en la mitad de los casos, si bien el desarrollo de candidiasis invasiva durante el embarazo o el periodo post-parto es excepcional. CASO CLÍNICO: Presentamos el caso de un recién nacido a término mediante parto vaginal asistido con ventosa de una mujer de 33 años aparentemente sana y en la que no se recogían antecedentes de uso de drogas por vía parenteral o candidiasis vaginal durante el embarazo. El neonato presentaba un exantema maculopapular difuso asociado a dificultad respiratoria e infiltrados pulmonares intersticiales bilaterales, por lo que precisó de soporte ventilatorio con presión positiva nasal contínua. Los hemocultivos realizados a partir de muestras de sangre de la madre debido a la presencia de fiebre intraparto fueron positivos para Candida albicans. Los cultivos de secreción vaginal y de la piel del neonato también revelaron C. albicans con idéntico perfil de sensibilidad in vitro. No se identificó ninguna fuente alternativa de candidemia. La evolución clínica fue favorable tanto en la madre como en el recién nacido tras el inicio de un tratamiento antifúngico, con aclaramiento de la candidemia y resolución de las lesiones cutáneas. CONCLUSIONES: El diagnóstico de CCC debe ser considerado en el recién nacido a término con exantema maculopapular al nacimiento o en los primeros días de vida. La ausencia de un origen alternativo de infección en nuestro caso sugiere una asociación etiopatogénica potencial entre la CCC y la candidemia materna. En escenarios sugerentes de CCC resulta razonable descartar la presencia de candidemia materna en el periodo post-parto

Evaluation of specific quality metrics to assess the performance of a specialised newborn transport programme.

There is a lack of consensus on quality indicators suitable for neonatal transport. The aim of this study is to make a proposal for specific quality indicators for newborn transport. A retrospective descriptive study was performed (2009 to 2015) where twenty-four indicators were selected, evaluated and classified according to the 6 dimensions of quality of the Institute of Medicine. Among the 24 evaluated quality metrics, there were 3 of them which needed a correction when evaluating neonatal transport performance, because they were significantly correlated with gestational age. They were (a) stabilisation time, (b) prevalence of newborn arterial hypotension (defined by gestational age) and (c) unnoticed hypothermia at referral hospital.Conclusion: Quality evaluation through the definition of specific metrics in newborn transport is feasible. These indicators should be defined or adjusted for newborn population to measure the actual performance of the transport service.What is Known:• Quality indicators may help in defining metrics for clinical practice, promoting benchmarking and defining areas of improvement.• Newborn characteristics call for a specialised care, and quality measure during newborn transport require specific metrics. Quality metrics for paediatric transport have been defined using Delphi method. Some of these measures need to be specific for newborn, due to their intrinsic characteristics.What is New:• Using evidence-based literature and our newborn transport experience, specific quality indicators for newborn transport are suggested.• Data analysis shows how some indicators need to be adjusted for gestational age.

Impact of a Developmental Care Training Course on the Knowledge and Satisfaction of Health Care Professionals in Neonatal Units: A Multicenter Study.

BACKGROUND: The impact of health-related continuing education courses on knowledge acquisition and clinical practice is infrequently evaluated, despite higher numbers of people enrolling in them. The majority of health care professionals working in neonatal intensive care units (NICUs) have received no training in developmental care (DC). The purpose of this study was to determine whether participation in a theoretical-practical course on DC had an effect on the degree of knowledge possessed by professionals in general terms and with respect to neonatal intensive care. The relationship between course satisfaction and knowledge acquisition was also studied. METHODS: This was an observational multicenter study conducted in 20 neonatal units in Madrid. A pre- and post-course questionnaire evaluated both knowledge and satisfaction levels regarding the course on DC and the Newborn Individualized Developmental Care and Assessment Program (NIDCAP). We carried out a multivariate linear regression analysis to determine whether there was a correlation between knowledge gained and satisfaction level. RESULTS: A total of 566 professionals participated, with a 99% pre-course and a 90% post-course response rate. The mean rate of correct pre-course answers was 65%, while the mean rate of post-course correct answers was 81% (p < 0.001). Results were similar at all levels of neonatal care (Level I: 64% vs 80%; Level II: 64% vs. 83%; and LEVEL III: 65% vs. 81%). Scores on a scale of satisfaction from 1 to 5 were high (averages of above 4 for all lectures and workshops). Pre-course knowledge scores, but not satisfaction, significantly influenced post-course knowledge (ß 0.499; p < 0.01). CONCLUSION: Previous DC knowledge among Madrid health care professionals was similar, regardless of the level of neonatal care. Course attendance significantly improved the rate of correct answers. Although course satisfaction was high, there did not seem to be a correlation between knowledge gained and satisfaction.

Determination of Acidity in Donor Milk.

BACKGROUND: There is no uniformity among milk banks on milk acceptance criteria. The acidity obtained by the Dornic titration technique is a widely used quality control in donor milk. However, there are no comparative data with other acidity-measuring techniques, such as the pH meter. OBJECTIVE: The objective of this study was to assess the correlation between the Dornic technique and the pH measure to determine the pH cutoff corresponding to the Dornic degree limit value used as a reference for donor milk quality control. METHODS: Fifty-two human milk samples were obtained from 48 donors. Acidity was measured using the Dornic method and pH meter in triplicate. Statistical data analysis to estimate significant correlations between variables was carried out. The Dornic acidity value that led to rejecting donor milk was ≥ 8 Dornic degrees (°D). RESULTS: In the evaluated sample size, Dornic acidity measure and pH values showed a statistically significant negative correlation (τ = -0.780; P = .000). A pH value of 6.57 corresponds to 8°D and of 7.12 to 4°D. CONCLUSION: Donor milk with a pH over 6.57 may be accepted for subsequent processing in the milk bank. Moreover, the pH measurement seems to be more useful due to certain advantages over the Dornic method, such as objectivity, accuracy, standardization, the lack of chemical reagents required, and the fact that it does not destroy the milk sample.

Tumor-induced rickets in a child with a central giant cell granuloma: a case report.

Tumor-induced osteomalacia/rickets is a rare paraneoplastic disorder associated with a tumor-producing fibroblast growth factor 23 (FGF23). We present a child with symptoms of rickets as the first clinical sign of a central giant cell granuloma (CGCG) with high serum levels of FGF23, a hormone associated with decreased phosphate resorption. A 3-year-old boy presented with a limp and 6 months later with painless growth of the jaw. On examination gingival hypertrophy and genu varum were observed. Investigations revealed hypophosphatemia, normal 1,25 and 25 (OH) vitamin D, and high alkaline phosphatase. An MRI showed an osteolytic lesion of the maxilla. Radiographs revealed typical rachitic findings. Incisional biopsy of the tumor revealed a CGCG with mesenchymal matrix. The CGCG was initially treated with calcitonin, but the lesions continued to grow, making it necessary to perform tracheostomy and gastrostomy. One year after onset the hyperphosphaturia worsened, necessitating increasing oral phosphate supplements up to 100 mg/kg per day of elemental phosphorus. FGF23 levels were extremely high. Total removal of the tumor was impossible, and partial reduction was achieved after percutaneous computed tomography-guided radiofrequency, local instillation of triamcinolone, and oral propranolol. Compassionate use of cinacalcet was unsuccessful in preventing phosphaturia. The tumor slowly regressed after the third year of disease; phosphaturia improved, allowing the tapering of phosphate supplements, and FGF23 levels normalized. Tumor-induced osteomalacia/rickets is uncommon in children and is challenging for physicians to diagnose. It should be suspected in patients with intractable osteomalacia or rickets. A tumor should be ruled out if FGF23 levels are high.
