Criterios de alta hospitalaria para el recién nacido de muy bajo peso al nacimiento

Hospital discharge criteria for the pre-term newborn are mainly based on physiological competences (thermoregulation, respiratory stability, and feeding skills), although family support and ability to care for the baby, as well as a well-planned discharge are also cornerstones to ensure a successful discharge. In this article, the Committee of Standards of the Spanish Society of Neonatology reviews the current hospital discharge criteria in order for it to be useful as a clinical guide in Spanish neonatal units.

Utilidad del propéptido natriurético cerebral en el diagnóstico y manejo del ductus arterioso permeable

INTRODUCTIONnPatent ductus arteriosus (PDA) is a prevalent condition in preterm infants, and may be related to increased morbidity and mortality in the most immature newborns. Recent studies have examined the usefulness of brain natriuretic propeptide (proBNP) in the diagnosis of this pathology. The aim of the study was to evaluate the diagnostic efficacy of proBNP as a marker of hemodynamic overload in PDA.nnnPAIENTS AND METHODSnA retrospective study was conducted on preterm infants less than 32 weeks of gestation and/or weight less than 1500 grams. Echocardiogram and determination of proBNP levels were performed on all patients. Comparison was made by subgroups according to the presence of PDA and their haemodynamic characteristics.nnnRESULTSnOf the 60 patients enrolled, 71.7% had PDA, of which 86% had haemodynamically significant patent ductus arteriosus (HS-PDA). All of them, but one, received medical treatment with ibuprofen or acetaminophen. Surgical closure was required in 29.7% of HS-PDA. Higher values of proBNP were found in patients with HS-PDA (33338±34494.47pg/mL; p=.000) compared with patients with closed or non-haemodynamically significant ductus arteriosus. Higher values were also found in patients who required surgical closure of PDA (30596.8±14910.9; p=.004). A greater decrease inproBNP levels was found in the group of patients which duct closure after pharmacological treatment (68±24.69% vs -12.22±99.4%; p=.030). ProBNP cutoff-level for HS-PDA was calculated by ROC curve and it was 9321.5pg/mL (Specificity: 100%, Sensitivity: 94.6%).nnnCONCLUSIONSnProBNP levels are related to the presence or absence of haemodynamically significant patent ductus arteriosus; and its variations with treatment response. High values are also related to the need for surgical closure of PDA.

Cribado de cardiopatías congénitas críticas en el periodo neonatal. Recomendación de la Sociedad Española de Neonatología

Due to its severity, as well as the consequences of a late diagnosis, critical congenital heart defects (CCHD) represent a challenging situation, making an early diagnosis necessary and ideally before symptoms appear when circulatory collapse or death of the newborn can occur. Due to this, a prenatal and very early postnatal diagnosis is very important. Prenatal ultrasound screening and physical examination of the newborn can miss a considerable number of CCHD cases. Pulse oximetry screening has been demonstrated to be an effective, non-invasive, inexpensive, and well accepted tool in the early diagnosis of CCHD. The Spanish National Society of Neonatology, through its Standards Committee, and based on the current evidence, recommend the implementation of pulse oximetry screening of CCHD in Spain, and then to offer the best therapy possible to these newborn infants.

Factores de riesgo y marcadores bioquímicos de la enfermedad metabólica ósea del recién nacido prematuro

BACKGROUNDnMetabolic bone disease (MBD) of prematurity is a complication of multifactorial aetiology, which has been increasing, due to progressive decrease in mortality of preterm newborns. The aim of the study was to analyze risk factors of severe MBD and its analytical markers.nnnPATIENTS AND METHODnRetrospective study involving preterm infants less than 32 weeks gestational age and/or weight less tan 1,500 g born between january 2012 and december 2014. Comparison was made according to the presence of severe MBD.nnnRESULTSn139 patients were recruited. Mean value of 25(OH)D3 was 70.68 ± 25.20 nmol/L, being higher in patients born in spring-summer than in autumn-winter (80.94 ± 25.33 vs 61.13 ± 21.07; p = 0.000). Levels of 25(OH)D3 were similar in patients with severe MBD compared with the rest of patients (65.61 ± 26.49 vs 72.07 ± 24.89, P = 0.283). Higher levels of alkaline phosphatase (AP, IU/L ) (1314.19 ± 506.67 vs 476.56 ± 188.85; p = 0.000) were found in these patients. Cutoff point of AP 796.5 IU/L (S 95.2%, specificity 92.4%) was calculated by ROC curve. The risk factors most associated to severe EMO were restricted fetal growth, birth weight, duration of ventilation therapy and parenteral nutrition.nnnCONCLUSIONSnAP levels were the best marker of severe MBD development. EMO risk increases with the number of risk factors and lower levels of 25(OH)D3. Levels of 25(OH)D3 higher than 70nmol/L appear to protect from the development of severe MBD, even in patients with multiple risk factors.Background: Metabolic bone disease (MBD) of prematurity is a complication of multifactorial aetiology, which has been increasing due to progressive decrease in mortality of preterm newborns.

Recomendaciones para la identificación inequívoca del recién nacido

Newborn identification is a legal right recognised by international and national laws. Moreover, improving the accuracy of correct patient identification is an important goal of patient safety solutions programs. In this article, the Standards Committee of the Spanish Society of Neonatology establishes recommendations to ensure correct identification of the newborn whilst in hospital. Currently, the most reliable method of identification of the newborn is the combination of identification cord clamp and bracelets (mother bracelet, newborn bracelet and cord clamp with the same number and identical and exclusive barcode system for each newborn) and the collection of maternal and umbilical cord blood samples (for DNA testing only for identification purposes).

Recomendaciones para la prevención, la detección y el manejo de la hiperbilirrubinemia en los recién nacidos con 35 o más semanas de edad gestacional

Hyperbilirubinaemia is one of the most frequent causes of hospital readmission during the first week of life. Its detection is still a big challenge, mainly due to the early discharge from the hospital that can be associated with a delay of the diagnosis. The identification of those newborns at risk of developing significant hyperbilirubinaemia is one of the main priorities in the public health care system. An approach to the management of newborn jaundice is presented in this article, following the recommendations based on the medical evidence and on the opinion of the Standards Committee of the Spanish Society of Neonatology.

Criterios de alta hospitalaria del recién nacido a término sano tras el parto

Criteria for newborn hospital discharge have to include physiological stability and family competence to provide newborn care at home. In this document, the Committee of Standards of the Spanish Society of Neonatology reviews the minimum criteria to be met before hospital discharge of a term newborn infant. We include a review of hospital discharge criteria for the late preterm infants, as these infants are often not hospitalised and remain with their mother after birth. A shortened hospital stay (less than 48h after delivery) for healthy term newborns can be considered, but it is not appropriate for every mother and newborn. Newborn infants discharged before 48h of age, should be examined within 3-4 days of life.
