Objective This study aimed to assess beliefs and attitudes of Argentinean neonatologists and neonatal nurses regarding end-of-life care of newborn infants, including withdrawal of clinically assisted nutrition and hydration (CANH). Study Design A five-domain survey was sent to 465 neonatal health care workers, which included demographic data, general ethical concepts, participation in end-of-life decisions, beliefs about end-of-life care practices, and presentation of four clinical scenarios. Standard statistical tests were used, and a multivariable analysis was done to evaluate variables independently associated with rejecting the withdrawal of CANH. Results A total of 227 questionnaires were anonymously completed, 60% by physicians and 40% by nurses. More respondents agreed to withdraw mechanical ventilation in comparison to CANH in patients under certain circumstances (88 vs. 62%, p < 0.01). The most accepted variables when deciding to withdraw care were the quality of life perceived by parents (86%) and their religious beliefs (73%). A total of 93% agreed that parents should be included in the decision, but only 74% acknowledged they are included in real practice. Considering the scenario of a newborn with severe and irreversible neurological compromise, 46% of respondents were opposed to suspending enteral nutrition. No independent variables were found to be associated with opposing the withdrawal of CANH. Of those agreeing to withdraw enteral feeds under certain circumstances, for the severely neurologically affected neonate 58% would either refuse to limit enteral feeds or consult with an ethics committee before doing so. When given the scenario of their own severe and irreversible neurological compromise, 68% agreed to have enteral feeds withdrawn to themselves, and they were more likely to agree with withdrawing feeds for the severely compromised neonate (odds ratio: 7.2; 95% confidence interval: 2.7–24.1). Conclusion While most health care providers agreed to withdraw life-sustaining support under certain conditions, many were reluctant to suspend CANH. Many responses differed when being asked as general statements versus actual clinical scenarios. Key Points Withdrawal of assisted nutrition is supported by the American Academy of Pediatrics in certain scenarios. Many neonatal intensive care units health care providers from Argentina are reluctant to suspend assisted nutrition. There is a need to learn how to deal with complex bioethical issues.

Background and Objectives: Nasal continuous positive airway pressure (NCPAP) is a useful method of respiratory support after extubation. However, some infants fail despite CPAP use and require reintubation. Some evidence suggests that synchronized nasal intermittent positive pressure ventilation (NIPPV) may decrease extubation failure in preterm infants. Nonsynchronized NIPPV (NS-NIPPV) is being widely used in preterm infants without conclusive evidence of its benefits and side effects. Our aim was to evaluate whether NS-NIPPV decreases extubation failure compared with NCPAP in ventilated very low birth weight infants (VLBWI) with respiratory distress syndrome (RDS). Methods: Randomized controlled trial of ventilated VLBWI being extubated for the first time. Before extubation, infants were randomized to receive NCPAP or NS-NIPPV. Primary outcome was the need for reintubation within 72 h. Results: 220 infants were included. The mean ± SD birth weight was 1,027 ± 256 g and gestational age 27.8 ± 1.9 weeks. Demographic and clinical characteristics were similar in both groups. Extubation failure was 32.4% for NCPAP versus 32.1% for NS-NIPPV, p = 0.98. The frequency of deaths, bronchopulmonary dysplasia, intraventricular hemorrhage, air leaks, necrotizing enterocolitis and duration of respiratory support did not differ between groups. Conclusions: In this population of VLBWI, NS-NIPPV did not decrease extubation failure after RDS compared with NCPAP. [ABSTRACT FROM AUTHOR]

Background Minimally invasive techniques for surfactant administration for infants with respiratory distress syndrome (RDS) of moderate severity have been proposed. The laryngeal mask airway (LMA) helps in securing the airway without the need of laryngoscopy, but still requires the use of positive pressure ventilation (PPV) to flush surfactant into the lungs. Objective This article compares the effectiveness of two techniques for LMA surfactant administration, instillation into the LMA lumen followed by PPV versus direct laryngeal instillation through a preinserted feeding tube inside the LMA during spontaneous respirations. Study Design This is a randomized controlled trial (RCT) of 18 rabbits with acquired respiratory distress after lung lavage. After surfactant was given, the rabbits remained on continuous positive airway pressure (CPAP). Gas exchange parameters were assessed at baseline and at 30 minutes and lung parenchyma pathology features were analyzed. Results Time required for surfactant administration, oxygenation improvement, and histopathologic findings did not differ between groups. The new technique decreased the need of PPV (p < 0.05). Conclusion In this animal model, surfactant administration through a preinserted feeding tube within the LMA lumen is safe and effective while providing the benefits of a minimally invasive approach. This technique reduces the need of PPV and may prevent its potential risks. [ABSTRACT FROM AUTHOR]

Objective: Alarm fatigue (AF) happens when professionals are exposed to many alarms and they become desensitized to them. It is related to proliferation of devices, not standardized alarm limits, and high prevalence of "nonactionable alarms," i.e., false alarms (triggered by equipment issues) or nuisance alarms (physiological change not requiring clinical action). When AF happens, response time seems to be longer and important alarms could be dismissed. After evaluating the situation in our neonatal intensive care unit (NICU), an alarm management program (AMP) was developed to reduce AF. The objective of this study were to compare the proportion of true alarms, nonactionable alarms, and to measure response time to alarms in the NICU before and after implementing an AMP and also to determine variables associated with nonactionable alarms and response time., Study Design: This was a cross-sectional study. A total of 100 observations were collected between December 2019 and January 2020. After an AMP was implemented, 100 new observations were collected between June 2021 and August 2021. We estimated the true and nonactionable alarms proportion. Univariate analyses were performed to determine variables associated with nonactionable alarms and response time. Logistic regression was performed to assess independent variables., Results: The proportion of true alarms before and after AMP was 31 versus 57% ( p  = 0.001), whereas the proportion of nonactionable alarms was 69 versus 43% ( p  = 0.001). Median response time was significantly reduced (35 versus 12 seconds; p  = 0.001). Before AMP, neonates with less intensive care needs had a higher proportion of nonactionable alarms and a longer response time. After AMP, response time was similar for true and nonactionable alarms. For both periods, the need of respiratory support was significantly associated with true alarms ( p  = 0.001). In the adjusted analysis, response time ( p  = 0.001) and respiratory support ( p  = 0.003) remained associated with nonactionable alarms., Conclusion: AF was highly prevalent in our NICU. This study shows that after the implementation of an AMP, response time to alarms and the proportion of nonactionable alarms can be significantly reduced., Key Points: · AF happens when professionals are exposed to many alarms and they become desensitized to them.. · The presence of AF can compromise patients' safety.. · The implementation of an AMP can reduce AF.., Competing Interests: None declared., (Thieme.

Introduction. With the use of aggressive parenteral nutrition in very low birth weight infants, alterations in calcium and phosphate metabolism were detected. In 2016, a prevention strategy was implemented through calcium phosphate monitoring and early supplementation. Our objective was to study whether this strategy reduces the prevalence of osteopenia and to identify associated risk factors. Population and methods. Quasi-experiment comparing the prevalence of osteopenia between two groups: one after implementing the calcium phosphate monitoring and supplementation strategy (01/01/2017-12/31/2019) and another prior to such intervention (01/01/2013-12/31/2015). Results. A total of 226 patients were included: 133 in the pre-intervention period and 93 in the post-intervention period. The overall prevalence of osteopenia was 26.1% (95% CI: 20.5-32.3) and it was reduced from 29.3% (95% CI: 21.7-37.8) in the pre-intervention period to 21.5% (95% CI: 13.6-31.2) in the post-intervention period, with no statistical significance (p = 0.19). In the multivariate analysis, the NEOCOSUR score for risk of death at birth, use of postnatal corticosteroids, and the intervention period were independently associated with osteopenia. Being born after the intervention reduced the probability of alkaline phosphatase > 500 IU/L by 71%, regardless of the other variables included in the model. Conclusion. Calcium phosphate monitoring and early supplementation is a protective factor against the development of osteopenia in very low birth weight infants., (Sociedad Argentina de Pediatría.)

Introduction: The objective of this study was to analyze available resources, guidelines in use, and preparedness to care for newborn infants at maternity centers in Argentina during the COVID-19 pandemic., Method: Cross-sectional study based on a survey administered to medical and nursing staff. In May 2020, Argentine facilities with more than 500 annual births were contacted; 58 % of these were from the public sector., Results: In total, 104/147 facilities answered (71 %). All had guidelines for care during the pandemic, and 93 % indicated they had been trained on how to use them. A companion was not allowed during childbirth in 26 % of private facilities and in 60 % of public ones (p < 0.01). Deferred cord clamping was recommended in 87 %; rooming-in with asymptomatic newborns was promoted in 62 %; breastfeeding using protective measures was recommended in 70 %; and breast milk using a bottle, in 23 %. In 94 %, family visiting in the Neonatology Unit was restricted. Difficulties included the unavailability of individual rooms for symptomatic newborn infants and a potential shortage of health care staff and personal protective equipment., Conclusions: All facilities are aware of the national guidelines to fight the pandemic. Most have the resources to comply with the recommended protective measures. There is uncertainty as to whether personal protective equipment, staff, and physical space available at the different facilities would be enough if cases increased significantly., Competing Interests: None, (Sociedad Argentina de Pediatría.)

Introduction: Morbidity and mortality are high in congenital diaphragmatic hernia. Some tools help to predict survival, both prenatally (observed/expected lung-to-head ratio [OELHR], presence of the liver in the chest) and postnatally (Congenital Diaphragmatic Hernia Study Group [CDHSG] score). Our objective was to identify the risk factors associated with mortality and estimate the risk-adjusted mortality in the prenatal period in the subgroup of patients with isolated left-sided hernia., Poulation and Methods: Retrospective and analytical study of patients born at Hospital Italiano de Buenos Aires between 2011 and 2018. A multivariate analysis was done to assess mortality-associated risk factors. For riskadjusted mortality in the prenatal period, the ratio between the observed mortality and the mean "expected" mortality based on the OELHR was estimated., Results: A total of 53 patients were included. Their median gestational age was 38 weeks, and their mean birth weight was 3054 g. Isolated hernia was observed in 73 % of patients. Overall mortality was 45 %, and higher in patients with associated malformations. In the multivariate analysis, the presence of severe pulmonary hypertension estimated by postnatal echocardiogram was independently associated with mortality (adjusted odds ratio: 6.4, 95 % confidence interval: 1.02-40). The observed overall mortality in patients with isolated left-sided hernia was similar to that expected (ratio: 1.05)., Conclusion: Overall mortality was similar to that expected based on the OE-LHR. In our population, severe pulmonary hypertension after birth was a determining factor of mortality., Competing Interests: None, (Sociedad Argentina de Pediatría.)

Introduction: Anemia is a complication in very low birth weight (VLBW) infants, and lab tests are a predominant risk factor. At least one red blood cell transfusion is given in more than 50 % of cases. Transfusions are associated with a higher risk for infections, intracranial hemorrhage, necrotizing enterocolitis, and bronchopulmonary dysplasia. In 2012, Hospital Italiano de Buenos Aires implemented a strategy to collect a lower blood volume by phlebotomy. The objective of this study was to assess its association with the number of transfusions., Methods: Before-and-after, quasi-experimental study. The number of transfusions was compared between two groups of VLBW preterm infants with different blood collection volumes. The correlation between the collection volume and the number of transfusions was assessed estimating Spearman's coefficient. A logistic regression model was used to adjust for confounders., Results: The study included 178 patients with a mean gestational age of 29.4 weeks (standard deviation: 2.7) and a birth weight of 1145 g (875-1345). The baseline red series profile was similar between both groups. The number of transfusions (p = 0.017) and the transfusion volume (p = 0.048) decreased significantly. The correlation coefficient was 0.83. In the multivariate analysis, collection volume and birth weight were associated with a requirement of more than three transfusions., Conclusion: A lower blood collection volume in VLBW preterm infants is independently associated with fewer transfusion requirements., Competing Interests: The authors report no conflicts of interest in this work., (Sociedad Argentina de Pediatría.)

Introduction: Bronchopulmonary dysplasia is the most common chronic pulmonary sequela among very low birth weight infants. The objective of this study was to estimate its incidence in our Neonatal Unit over the past 5 years and analyze associated risk factors., Population and Methods: An observational and analytical study was conducted in a retrospective cohort, using data obtained from a prospective database of infants born at Hospital Italiano de Buenos Aires with a birth weight of less than 1500 grams between January 2010 and December 2014. The incidence of bronchopulmonary dysplasia and its association with several secondary outcome measures were studied., Results: Two hundred and forty-five patients were included. The incidence of moderate/severe bronchopulmonary dysplasia was 22%, and it was associated with a younger gestational age and lower birth weight. A significant association was observed with surfactant use, mechanical ventilation requirement, and length of mechanical ventilation. Patients with moderate/severe bronchopulmonary dysplasia had a higher incidence of patent ductus arteriosus and late-onset sepsis. A lower birth weight (adjusted odds ratio |-#91;aOR|-#93;: 0.99, 95% confidence interval |-#91;CI|-#93;: 0.991-0.997, p< 0.001) and the length of mechanical ventilation (aOR: 1.08, 95% CI: 1.01-1.15, p < 0.01) remained associated following adjustment for other outcome measures. In addition, an association was observed among patients with intrauterine growth restriction born at less than 32 weeks of gestational age (OR: 4.71, 95% CI: 1.68-13.2)., Conclusions: The incidence ofbronchopulmonary dysplasia in our unit was associated with a lower birth weight and the length of mechanical ventilation. Among infants born at less than 32 weeks of gestation, intrauterine growth restriction accounted for an additional risk.
