Endotracheal Tube Size Adjustments Within Seven Days of Neonatal Intubation

BACKGROUND AND OBJECTIVES

Neonatal endotracheal tube (ETT) size recommendations are based on limited evidence. We sought to determine data-driven weight-based ETT sizes for infants undergoing tracheal intubation and to compare these with Neonatal Resuscitation Program (NRP) recommendations.

METHODS

Retrospective multicenter cohort study from an international airway registry. We evaluated ETT size changes (downsizing to a smaller ETT during the procedure or upsizing to a larger ETT within 7 days) and risk of procedural adverse outcomes associated with first-attempt ETT size selection when stratifying the cohort into 200 g subgroups.

RESULTS

Of 7293 intubations assessed, the initial ETT was downsized in 5.0% of encounters and upsized within 7 days in 1.5%. ETT downsizing was most common when NRP-recommended sizes were attempted in the following weight subgroups: 1000 to 1199 g with a 3.0 mm (12.6%) and 2000 to 2199 g with a 3.5 mm (17.1%). For infants in these 2 weight subgroups, selection of ETTs 0.5 mm smaller than NRP recommendations was independently associated with lower odds of adverse outcomes compared with NRP-recommended sizes. Among infants weighing 1000 to 1199 g: any tracheal intubation associated event, 20.8% with 2.5 mm versus 21.9% with 3.0 mm (adjusted OR [aOR] 0.62, 95% confidence interval [CI] 0.41-0.94); severe oxygen desaturation, 35.2% with 2.5 mm vs 52.9% with 3.0 mm (aOR 0.53, 95% CI 0.38-0.75). Among infants weighing 2000 to 2199 g: severe oxygen desaturation, 41% with 3.0 mm versus 56% with 3.5mm (aOR 0.55, 95% CI 0.34-0.89).

CONCLUSIONS

For infants weighing 1000 to 1199 g and 2000 to 2199 g, the recommended ETT size was frequently downsized during the procedure, whereas 0.5 mm smaller ETT sizes were associated with fewer adverse events and were rarely upsized.

Validity Evidence for a Novel, Comprehensive Bag-Mask Ventilation Assessment Tool

OBJECTIVE

To develop a comprehensive competency assessment tool for pediatric bag-mask ventilation (pBMV) and demonstrate multidimensional validity evidence for this tool.

STUDY DESIGN

A novel pBMV assessment tool was developed consisting of 3 components: a 22-item-based checklist (trichotomized response), global rating scale (GRS, 5-point), and entrustment assessment (4-point). Participants' performance in a realistic simulation scenario was video-recorded and assessed by blinded raters. Multidimensional validity evidence for procedural assessment, including evidence for content, response-process, internal structure, and relation to other variables, was assessed. The scores of each scale were compared with training level. Item-based checklist scores also were correlated with GRS and entrustment scores.

RESULTS

Fifty-eight participants (9 medical students, 10 pediatric residents, 18 critical care/neonatology fellows, 21 critical care/neonatology attendings) were evaluated. The pBMV tool was supported by high internal consistency (Cronbach α = 0.867). Inter-rater reliability for the item-based checklist component was acceptable (r = 0.65, P < .0001). The item-based checklist scores differentiated between medical students and other providers (P < .0001), but not by other trainee level. GRS and entrustment scores significantly differentiated between training levels (P < .001). Correlation between skill item-based checklist and GRS was r = 0.489 (P = .0001) and between item-based checklist and entrustment score was r = 0.52 (P < .001). This moderate correlation suggested each component measures pBMV skills differently. The GRS and entrustment scores demonstrated moderate inter-rater reliability (0.42 and 0.46).

CONCLUSIONS

We established evidence of multidimensional validity for a novel entrustment-based pBMV competence assessment tool, incorporating global and entrustment-based assessments. This comprehensive tool can provide learner feedback and aid in entrustment decisions as learners progress through training.

Does videolaryngoscopy improve tracheal intubation first attempt success in the NICUs? A report from the NEAR4NEOS

OBJECTIVE

We hypothesized that videolaryngoscope use for tracheal intubations would differ across NICUs, be associated with higher first attempt success and lower adverse events.

STUDY DESIGN

Data from the National Emergency Airway Registry for Neonates (01/2015 to 12/2017) included intubation with direct laryngoscope or videolaryngoscope. Primary outcome was first attempt success. Secondary outcomes were adverse tracheal intubation associated events and severe desaturation.

RESULTS

Of 2730 encounters (13 NICUs), 626 (23%) utilized a videolaryngoscope (3% to 64% per site). Videolaryngoscope use was associated with higher first attempt success (p < 0.001), lower adverse tracheal intubation associated events (p < 0.001), but no difference in severe desaturation. After adjustment, videolaryngoscope use was not associated with higher first attempt success (OR:1.18, p = 0.136), but was associated with lower tracheal intubation associated events (OR:0.45, p < 0.001).

CONCLUSION

Videolaryngoscope use is variable, not independently associated with higher first attempt success but associated with fewer tracheal intubation associated events.

Management of newborns exposed to mothers with confirmed or suspected COVID-19

There is limited information about newborns with confirmed or suspected COVID-19. Particularly in the hospital after delivery, clinicians have refined practices in order to prevent secondary infection. While guidance from international associations is continuously being updated, all facets of care of neonates born to women with confirmed or suspected COVID-19 are center-specific, given local customs, building infrastructure constraints, and availability of protective equipment. Based on anecdotal reports from institutions in the epicenter of the COVID-19 pandemic close to our hospital, together with our limited experience, in anticipation of increasing numbers of exposed newborns, we have developed a triage algorithm at the Penn State Hospital at Milton S. Hershey Medical Center that may be useful for other centers anticipating a similar surge. We discuss several care practices that have changed in the COVID-19 era including the use of antenatal steroids, delayed cord clamping (DCC), mother-newborn separation, and breastfeeding. Moreover, this paper provides comprehensive guidance on the most suitable respiratory support for newborns during the COVID-19 pandemic. We also present detailed recommendations about the discharge process and beyond, including providing scales and home phototherapy to families, parental teaching via telehealth and in-person education at the doors of the hospital, and telehealth newborn follow-up.

Term Neonate Presenting with the Combined Occurrence of Mucolipidosis Type II and Leigh Syndrome

Mucolipidosis II α/beta (MLII) is an autosomal recessive disease in which a gene mutation leads to improper targeting of lysosomal enzymes with an end result of accumulation of lysosomes in the mitochondria resulting in a dysfunctional mitochondria. 1 Leigh syndrome (LS) is a rare progressive neurodegenerative disorder associated with dysfunctional mitochondria and oxidative phosphorylation. 4 Both disease processes typically present in infancy. 3 7 Herein, we present a case of an infant diagnosed with both mucolipidosis II and Leigh syndrome. Genetic analysis in this case revealed two mutations (NDUFA12 c.178C > T p.Arg60* and GNPTAB c.732_733delAA) on the long arm of chromosome 12 as the etiology of MLII and LS in this neonate, respectively. We are unaware of any previously published cases of the presence of these two diseases occurring in the same patient. The complex clinical presentation of this case led to a delay in the diagnosis, and we believe that the clinical phenotypes of these two conditions were likely worsened. The genetic alterations presented in this case occurred as a result of mutations on chromosome 12. We suggest further investigation into the potential overlap in the pathophysiology, specifically the inheritance pattern, linkage disequilibrium, mitochondrial-lysosomal interaction, or crosstalk contributing to both diseases.

Comparison of Neonatal Intubation Practice and Outcomes between the Neonatal Intensive Care Unit and Delivery Room

BACKGROUND

Characteristics of neonatal tracheal intubations (TI) may vary between the neonatal intensive care unit (NICU) and delivery room (DR). The impact of the setting on TI outcomes is not well characterized.

OBJECTIVE

The aim of this study was to define variation in neonatal TI practice between settings, and identify the association between setting and TI success and safety outcomes.

DESIGN

This was a retrospective cohort study of TIs in the National Emergency Airway Registry for Neonates from October 2014 to September 2017. The setting (NICU vs. DR) was the exposure of interest. The outcomes were first attempt success, course success, success within 4 attempts, adverse TI-associated events, severe desaturation, and bradycardia. We compared TI characteristics and outcomes between settings in univariable analysis. Factors significant in univariable analysis (p < 0.1) were included in a logistic regression model, with adjustment for clustering by center, to identify the independent impact of the setting on TI outcomes.

RESULTS

There were 3,145 TI encounters (2279 NICU, 866 DR) in 9 centers. Almost all baseline characteristics significantly varied between settings. First attempt success rates were 48% (NICU) and 46% (DR). In multivariable analysis, the setting was not associated with first attempt success. DR was associated with a higher adjusted OR (aOR) of success within 4 attempts (1.48, 95% CI 1.06-2.08) and a lower aOR for bradycardia (0.43, 95% CI 0.26-0.71).

CONCLUSION

Significant differences in patient, provider, and practice characteristics exist between NICU and DR TIs. There is substantial room for improvement in first attempt success rates. These results suggest interventions to improve safety and success need to be targeted to the distinct setting.

Neonatal Intubation Practice and Outcomes: An International Registry Study

BACKGROUND AND OBJECTIVES

Neonatal tracheal intubation is a critical but potentially dangerous procedure. We sought to characterize intubation practice and outcomes in the NICU and delivery room (DR) settings and to identify potentially modifiable factors to improve neonatal intubation safety.

METHODS

We developed the National Emergency Airway Registry for Neonates and collected standardized data for patients, providers, practices, and outcomes of neonatal intubation. Safety outcomes included adverse tracheal intubation-associated events (TIAEs) and severe oxygen desaturation (≥20% decline in oxygen saturation). We examined the relationship between intubation characteristics and adverse events with univariable tests and multivariable logistic regression.

RESULTS

We captured 2009 NICU intubations and 598 DR intubations from 10 centers. Pediatric residents attempted 15% of NICU and 2% of DR intubations. In the NICU, the first attempt success rate was 49%, adverse TIAE rate was 18%, and severe desaturation rate was 48%. In the DR, 46% of intubations were successful on the first attempt, with 17% TIAE rate and 31% severe desaturation rate. Site-specific TIAE rates ranged from 9% to 50% (P < .001), and severe desaturation rates ranged from 29% to 69% (P = .001). Practices independently associated with reduced TIAEs in the NICU included video laryngoscope (adjusted odds ratio 0.46, 95% confidence interval 0.28-0.73) and paralytic premedication (adjusted odds ratio 0.38, 95% confidence interval 0.25-0.57).

CONCLUSIONS

We implemented a novel multisite neonatal intubation registry and identified potentially modifiable factors associated with adverse events. Our results will inform future interventional studies to improve neonatal intubation safety.

Oropharyngeal Administration of Colostrum Increases Salivary Secretory IgA Levels in Very Low-Birth-Weight Infants

AIM

Oropharyngeal administration of colostrum (OAC) has been proposed to provide mother's early milk to very low-birth-weight (VLBW) infants in the first few days of life. The aim of this study was to test the hypothesis that OAC would increase salivary secretory IgA (SsIgA).

METHODS

Overall, 30 VLBW infants randomized to receive OAC or sterile water had salivary sampling for SsIgA on the day of life (DOL) 2,7, and 14. The incidence of late-onset sepsis (LOS) and necrotizing enterocolitis (NEC) was determined prospectively. Within and between-group comparisons were made by paired and independent samples t-tests.

RESULTS

Baseline characteristics were similar between groups. SsIgA was higher in OAC versus the control group (p < 0.05) on DOL 7, but not subsequently on DOL 14. There was no difference in LOS or NEC.

CONCLUSION

OAC increased SsIgA at DOL 7. A large, multicenter trial is needed to determine if OAC decreases LOS or NEC in VLBW infants.

Cost-effective and low-technology options for simulation and training in neonatology

The purpose of this review is to explore low-cost options for simulation and training in neonatology. Numerous cost-effective options exist for simulation and training in neonatology. Lower cost options are available for teaching clinical skills and procedural training in neonatal intubation, chest tube insertion, and pericardiocentesis, among others. Cost-effective, low-cost options for simulation-based education can be developed and shared in order to optimize the neonatal simulation training experience.
