Aim: Oxygen saturation is frequently monitored with pulse oximetry to assess vital signs in critically ill patients. Optimally, pulse oximetry closely tracks arterial oxygen tension (PaO2), which provides guidance in oxygen titration. We investigated whether monitoring peripheral oxygen saturation (SpO2) could accurately guide oxygen titration in newborn infants.Methods: Twenty seven thousand two hundred thirty seven SpO2 readings were retrospectively paired with arterial oxygen saturation (SaO2) and PaO2 results from blood gas analyses performed in infants with arterial catheters in place.Results: SpO2 overestimated SaO2 readings by 2.9 ± 5.8%. When pulse oximetry readings were within the defined oxygen saturation target range, 7809 (20.9%) SaO2 values were below and 2830 (7.6%) exceeded the target range. In 57% of patients, PaO2 levels < 6 kPa was diagnosed while SpO2 readings were > 90%. PaO2 > 11 kPa was recorded in 19% of cases, when SpO2 readings were < 95%. Infants treated with supplemental oxygen showed a threefold increased risk of hypoxaemia compared to infants breathing room air. Sensitivity and specificity for detecting upper and lower target range limits were fair to good. For SpO2 values below 91%, ISO quality criteria were no longer fulfilled.Conclusions: Based on arterial blood gas analyses as reference, pulse oximetry readings did not fulfil the performance requirements for titrating oxygen in neonatal patients.

Enteral supplementation with arachidonic acid (AA) and docosahexaenoic acid (DHA) in extremely preterm infants has shown beneficial effects on retinopathy of prematurity and pulmonary outcome whereas exclusive DHA supplementation has been associated with increased pulmonary morbidity. This secondary analysis evaluates pulmonary outcome in 204 extremely preterm infants, randomized to receive AA (100 mg/kg/day) and DHA (50 mg/kg/day) enterally from birth until term age or standard care. Pulmonary morbidity was primarily assessed based on severity of bronchopulmonary dysplasia (BPD). Serum levels of AA and DHA during the first 28 days were analysed in relation to BPD. Supplementation with AA:DHA was not associated with increased BPD severity, adjusted OR 1.48 (95 % CI 0.85-2.61), nor with increased need for respiratory support at post menstrual age 36 weeks or duration of oxygen supplementation. Every 1 % increase in AA was associated with a reduction of BPD severity, adjusted OR 0.73 (95 % CI 0.58-0.92). In conclusion, in this study, with limited statistical power, enteral supplementation with AA:DHA was not associated with an increased risk of pulmonary morbidity, but higher levels of AA were associated with less severe BPD. Whether AA or the combination of AA and DHA have beneficial roles in the immature lung needs further research.

Parenteral nutrition (PN) is recognized as a complex high-risk therapy. Its practice is highly variable and frequently suboptimal in pediatric patients. Optimizing care requires evidence, consensus-based guidelines, audits of practice, and standardized strategies. Several pediatric scientific organizations, expert panels, and authorities have recently recommended that standardized PN should generally be used over individualized PN in the majority of pediatric patients including very low birth weight premature infants. In addition, PN admixtures produced and validated by a suitably qualified institution are recommended over locally produced PN. Licensed multi chamber bags are standardized PN bags that comply with Good Manufacturing Practice and high-quality standards for the finished product in the frame of their full manufacturing license. The purpose of this article is to review the practical aspects of PN and the evidence for using such multi-chamber bags in pediatric patients. It highlights the safety characteristics and the limitations of the different PN practices and provides some guidance for ensuring safe and efficient therapy in pediatric patients.

Aim: To explore the incidence and characteristics of inpatient neonatal adverse events in a Swedish setting.Methods: A retrospective record review, using a trigger tool, performed by registered nurses and a neonatologist, at a University Hospital. The identified adverse events were categorised by, for example, preventability, severity and time of occurrence.Results: A random selection of 150 admissions representing 3531 patient days were reviewed (mean [SD] birthweight 2620 [1120]g). Three hundred and sixty adverse events were identified in 78 (52.0%) infants, and 305 (84.7%) of these were assessed as being preventable. The overall adverse event rate was 240 per 100 admissions and 102.0 per 1000 patient days. Preterm infants had a higher rate than term infants (353 versus 79 per 100 admissions, p = 0.001); however, with regard to the length of stay, the rates were similar. Most adverse events were temporary and less severe (n = 338/360, 93.9%) and the most common type involved harm to skin, tissue or blood vessels (n = 163/360, 45.3%). Forty percent (n = 145) of adverse events occurred within the first week of admission.Conclusion: Adverse events were common in neonatal care, and many occurred during the first days of treatment. Characterisation of adverse events may provide focus areas for improvements in patient safety.
