Objectives: Children with trisomy 21 often have anatomic and physiologic features that may complicate tracheal intubation (TI). TI in critically ill children with trisomy 21 is not well described. We hypothesize that in children with trisomy 21, TI is associated with greater odds of adverse airway outcomes (AAOs), including TI-associated events (TIAEs), and peri-intubation hypoxemia (defined as > 20% decrease in pulse oximetry saturation [Sp o2 ])., Design: Retrospective database study using the National Emergency Airway Registry for Children (NEAR4KIDS)., Setting: Registry data from 16 North American PICUs and cardiac ICUs (CICUs), from January 2014 to December 2020., Patients: A cohort of children under 18 years old who underwent TI in the PICU or CICU from in a NEAR4KIDS center. We identified patients with trisomy 21 and selected matched cohorts within the registry., Interventions: None., Measurements and Main Results: We included 8401 TIs in the registry dataset. Children with trisomy 21 accounted for 274 (3.3%) TIs. Among those with trisomy 21, 84% had congenital heart disease and 4% had atlantoaxial instability. Cervical spine protection was used in 6%. The diagnosis of trisomy 21 (vs. without) was associated with lower median weight 7.8 (interquartile range [IQR] 4.5-14.7) kg versus 10.6 (IQR 5.2-25) kg ( p < 0.001), and more higher percentage undergoing TI for oxygenation (46% vs. 32%, p < 0.001) and ventilation failure (41% vs. 35%, p = 0.04). Trisomy 21 patients had more difficult airway features (35% vs. 25%, p = 0.001), including upper airway obstruction (14% vs. 8%, p = 0.001). In addition, a greater percentage of trisomy 21 patients received atropine (34% vs. 26%, p = 0.004); and, lower percentage were intubated with video laryngoscopy (30% vs. 37%, p = 0.023). After 1:10 (trisomy 21:controls) propensity-score matching, we failed to identify an association difference in AAO rates (absolute risk difference -0.6% [95% CI -6.1 to 4.9], p = 0.822)., Conclusions: Despite differences in airway risks and TI approaches, we have not identified an association between the diagnosis of trisomy 21 and higher AAOs., Competing Interests: Drs.

Objectives: To describe tracheal intubation (TI) practice by Advanced Practice Registered Nurses (APRNs) in North American PICUs, including rates of TI-associated events (TIAEs) from 2015 to 2019., Design/setting: Retrospective study using the National Emergency Airway Registry for Children with all TIs performed in PICU and pediatric cardiac ICU between January 2015 and December 2019. The primary outcome was first attempt TI success rate. Secondary outcomes were TIAEs, severe TIAEs, and hypoxemia., Subjects: Critically ill children requiring TI in a PICU or pediatric cardiac ICU., Interventions: None., Measurements and Main Results: Among 11,012 TIs, APRNs performed 1,626 (14.7%). Overall, TI by APRNs, compared with other clinicians, occurred less frequently in patients with known difficult airway (11.1% vs. 14.3%; p < 0.001), but more frequently in infants younger than 1 year old (55.9% vs. 44.4%; p < 0.0001), and in patients with cardiac disease (26.3% vs. 15.9%; p < 0.0001).There was lower odds of success in first attempt TI for APRNs vs. other clinicians (adjusted odds ratio, 0.70; 95% CI, 0.62-0.79). We failed to identify a difference in rates of TIAE, severe TIAE, and oxygen desaturation events for TIs by APRNs compared with other clinicians. The TI first attempt success rate improved with APRN experience (< 1 yr: 54.2%, 1-5 yr: 59.4%, 6-10 yr: 67.6%, > 10 yr: 63.1%; p = 0.021)., Conclusions: TI performed by APRNs was associated with lower odds of first attempt success when compared with other ICU clinicians although there was no appreciable difference in procedural adverse events. There appears to be a positive relationship between experience and success rates. These data suggest there is an ongoing need for opportunities to build on TI competency with APRNs., Competing Interests: Dr. Polikoff received funding from Novavax. Drs.

Objectives: Extremes of patient body mass index are associated with difficult intubation and increased morbidity in adults. We aimed to determine the association between being underweight or obese with adverse airway outcomes, including adverse tracheal intubation (TI)-associated events (TIAEs) and/or severe peri-intubation hypoxemia (pulse oximetry oxygen saturation < 80%) in critically ill children., Design/setting: Retrospective cohort using the National Emergency Airway for Children registry dataset of 2013-2020., Patients: Critically ill children, 0 to 17 years old, undergoing TI in PICUs., Interventions: None., Measurements and Main Results: Registry data from 24,342 patients who underwent TI between 2013 and 2020 were analyzed. Patients were categorized using the Centers for Disease Control and Prevention weight-for-age chart: normal weight (5th-84th percentile) 57.1%, underweight (< 5th percentile) 27.5%, overweight (85th to < 95th percentile) 7.2%, and obese (≥ 95th percentile) 8.2%. Underweight was most common in infants (34%); obesity was most common in children older than 8 years old (15.1%). Underweight patients more often had oxygenation and ventilation failure (34.0%, 36.2%, respectively) as the indication for TI and a history of difficult airway (16.7%). Apneic oxygenation was used more often in overweight and obese patients (19.1%, 19.6%) than in underweight or normal weight patients (14.1%, 17.1%; p < 0.001). TIAEs and/or hypoxemia occurred more often in underweight (27.1%) and obese (24.3%) patients ( p < 0.001). TI in underweight children was associated with greater odds of adverse airway outcome compared with normal weight children after adjusting for potential confounders (underweight: adjusted odds ratio [aOR], 1.09; 95% CI, 1.01-1.18; p = 0.016). Both underweight and obesity were associated with hypoxemia after adjusting for covariates and site clustering (underweight: aOR, 1.11; 95% CI, 1.02-1.21; p = 0.01 and obesity: aOR, 1.22; 95% CI, 1.07-1.39; p = 0.002)., Conclusions: In underweight and obese children compared with normal weight children, procedures around the timing of TI are associated with greater odds of adverse airway events., Competing Interests: Ms. Napolitano’s, Dr. Shults’s, Dr. Nadkarni’s, and Dr. Nishisaki’s institution received funding from the Agency for Healthcare Research and Quality (R18HS024511).

Background: Nasal tracheal intubation (TI) represents a minority of all TI in the pediatric intensive care unit (PICU). The risks and benefits of nasal TI are not well quantified. As such, safety and descriptive data regarding this practice are warranted., Methods: We evaluated the association between TI route and safety outcomes in a prospectively collected quality improvement database (National Emergency Airway Registry for Children: NEAR4KIDS) from 2013 to 2020. The primary outcome was severe desaturation (SpO 2  > 20% from baseline) and/or severe adverse TI-associated events (TIAEs), using NEAR4KIDS definitions. To balance patient, provider, and practice covariates, we utilized propensity score (PS) matching to compare the outcomes of nasal vs. oral TI., Results: A total of 22,741 TIs [nasal 870 (3.8%), oral 21,871 (96.2%)] were reported from 60 PICUs. Infants were represented in higher proportion in the nasal TI than the oral TI (75.9%, vs 46.2%), as well as children with cardiac conditions (46.9% vs. 14.4%), both p  < 0.001. Severe desaturation or severe TIAE occurred in 23.7% of nasal and 22.5% of oral TI (non-adjusted p  = 0.408). With PS matching, the prevalence of severe desaturation and or severe adverse TIAEs was 23.6% of nasal vs. 19.8% of oral TI (absolute difference 3.8%, 95% confidence interval (CI): - 0.07, 7.7%), p  = 0.055. First attempt success rate was 72.1% of nasal TI versus 69.2% of oral TI, p  = 0.072. With PS matching, the success rate was not different between two groups (nasal 72.2% vs. oral 71.5%, p  = 0.759)., Conclusion: In this large international prospective cohort study, the risk of severe peri-intubation complications was not significantly higher. Nasal TI is used in a minority of TI in PICUs, with substantial differences in patient, provider, and practice compared to oral TI.A prospective multicenter trial may be warranted to address the potential selection bias and to confirm the safety of nasal TI., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s) 2024.)

Objective: Our objective is to characterize the incidence of tracheostomy placement and of new requirement for long-term mechanical ventilation after extracorporeal membrane oxygenation (ECMO) among children with acute respiratory failure. We examine whether an association exists between demographics, pre-ECMO and ECMO clinical factors, and the placement of a tracheostomy or need for long-term mechanical ventilation., Methods: A retrospective multicenter cohort study was conducted at 10 quaternary care pediatric academic centers, including children supported with veno-venous (V-V) ECMO from 2011 to 2016., Results: Among 202 patients, 136 (67%) survived to ICU discharge. All tracheostomies were placed after ECMO decannulation, in 22 patients, with 19 of those surviving to ICU discharge (14% of survivors). Twelve patients (9% of survivors) were discharged on long-term mechanical ventilation. Tracheostomy placement and discharge on home ventilation were not associated with pre-ECMO severity of illness or pre-existing chronic illness. Patients who received a tracheostomy were older and weighed more than patients who did not receive a tracheostomy, although this association did not exist among patients discharged on home ventilation. ECMO duration was longer in those who received a tracheostomy compared with those who did not, as well as for those discharged on home ventilation, compared to those who were not., Conclusion: The 14% rate for tracheostomy placement and 9% rate for discharge on long-term mechanical ventilation after V-V ECMO are important patient-centered findings. This study informs anticipatory guidance provided to families of patients requiring prolonged respiratory ECMO support, and lays the foundation for future research., (© 2021 Wiley Periodicals LLC.)

This study seeks to evaluate the association between acute kidney injury (AKI), fluid overload (FO), and mortality in children supported with extracorporeal membrane oxygenation (ECMO) for refractory respiratory failure. This retrospective observational cohort study was performed at six tertiary care children's hospital intensive care units, studying 424 patients < 18 years of age supported with ECMO for ≥ 24 hours for a respiratory indication from January 1, 2007, to December 31, 2011. In a multivariate analysis, FO level at ECMO initiation was not associated with hospital mortality, whereas peak FO level during ECMO was associated with hospital mortality. For every 10% increase in peak FO during ECMO, the odds of hospital mortality were approximately 1.2 times higher. Every 10% increase in peak FO during ECMO resulted in a significant relative change in the duration of ECMO hours by a factor of 1.08. For hospital survivors, every 10% increase in peak FO level during ECMO resulted in a significant relative change in the duration of mechanical ventilation hours by a factor of 1.13. In this patient population, AKI and FO are associated with increased mortality and should be considered targets for medical interventions including judicious fluid management, diuretic use, and renal replacement therapy.
