RESUMEN
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.

OBJECTIVES: To evaluate the impact of point-of-care ultrasound (POCUS) use on clinicians within a PICU and to assess infrastructural elements of our POCUS program development. DESIGN: Retrospective observational study. SETTING: Large academic, noncardiac PICU in the United States. SUBJECTS: Patients in a PICU who had diagnostic POCUS performed. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Between January 1, 2017, and December 31, 2022, 7201 diagnostic POCUS studies were ordered; 1930 (26.8%) had a quality assurance (QA) record generated in an independent POCUS QA database. The cardiac domain was most frequently imaged (81.0% of ordered studies, 81.2% of reviewed studies). POCUS images changed clinician understanding of pathophysiology in 563 of 1930 cases (29.2%); when this occurred, management was changed in 318 of 563 cases (56.5%). Cardiac POCUS studies altered clinician suspected pathophysiology in 30.1% of cases (472/1568), compared with 21.5% (91/362) in noncardiac studies (p = 0.06). Among cases where POCUS changed clinician understanding, management changed more often following cardiac than noncardiac POCUS (p = 0.02). Clinicians identified a need for cardiology consultation or complete echocardiograms in 294 of 1568 cardiac POCUS studies (18.8%). Orders for POCUS imaging increased by 94.9%, and revenue increased by 159.4%, from initial to final study year. QA database use by both clinicians and reviewers decreased annually as QA processes evolved in the setting of technologic growth and unit expansion. CONCLUSIONS: Diagnostic POCUS imaging in the PICU frequently yields information that alters diagnosis and changes management. As PICU POCUS use increased, QA processes evolved resulting in decreased use of our initial QA database. Modifications to QA processes are likely necessary as clinical contexts change over time.
RESUMEN
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.

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.

BACKGROUND: Ketamine has traditionally been avoided for tracheal intubations (TIs) in patients with acute neurological conditions. We evaluate its current usage pattern in these patients and any associated adverse events. METHODS: We conducted a retrospective observational cohort study of critically ill children undergoing TI for neurological indications in 53 international pediatric intensive care units and emergency departments. We screened all intubations from 2014 to 2020 entered into the multicenter National Emergency Airway Registry for Children (NEAR4KIDS) registry database. Patients were included if they were under the age of 18 years and underwent TI for a primary neurological indication. Usage patterns and reported periprocedural composite adverse outcomes (hypoxemia < 80%, hypotension/hypertension, cardiac arrest, and dysrhythmia) were noted. RESULTS: Of 21,562 TIs, 2,073 (9.6%) were performed for a primary neurological indication, including 190 for traumatic brain injury/trauma. Patients received ketamine in 495 TIs (23.9%), which increased from 10% in 2014 to 41% in 2020 (p < 0.001). Ketamine use was associated with a coindication of respiratory failure, difficult airway history, and use of vagolytic agents, apneic oxygenation, and video laryngoscopy. Composite adverse outcomes were reported in 289 (13.9%) Tis and were more common in the ketamine group (17.0% vs. 13.0%, p = 0.026). After adjusting for location, patient age and codiagnoses, the presence of respiratory failure and shock, difficult airway history, provider demographics, intubating device, and the use of apneic oxygenation, vagolytic agents, and neuromuscular blockade, ketamine use was not significantly associated with increased composite adverse outcomes (adjusted odds ratio 1.34, 95% confidence interval CI 0.99-1.81, p = 0.057). This paucity of association remained even when only neurotrauma intubations were considered (10.6% vs. 7.7%, p = 0.528). CONCLUSIONS: This retrospective cohort study did not demonstrate an association between procedural ketamine use and increased risk of peri-intubation hypoxemia and hemodynamic instability in patients intubated for neurological indications.

OBJECTIVES: Early shock reversal is crucial to improve patient outcomes. Capillary refill time (CRT) is clinically important to identify and monitor shock in children but has issues with inconsistency. To minimize inconsistency, we evaluated a CRT monitoring system using an automated compression device. Our objective was to determine proper compression pressure in children. METHODS: Clinician force for CRT was collected during manual CRT measurement as a reference for automated compression in a previous study (12.9 N, 95% confidence interval, 12.5-13.4; n = 454). An automated compression device with a soft inflation bladder was fitted with a force sensor. We evaluated the effectiveness of the automated pressure to eliminate pulsatile blood flow from the distal phalange. Median and variance of CRT analysis at each pressure was compared. RESULTS: A comparison of pressures at 300 to 500 mm Hg on a simulated finger yielded a force of 5 to 10 N, and these pressures were subsequently used for automated compression for CRT. Automated compression was tested in 44 subjects (median age, 33 months; interquartile range [IQR], 14-56 months). At interim analysis of 17 subjects, there was significant difference in the waveform with residual pulsatile blood flow (9/50: 18% at 300 mm Hg, 5/50:10% at 400 mm Hg, 0/51: 0% at 500 mm Hg, P = 0.008). With subsequent enrollment of 27 subjects at 400 and 500 mm Hg, none had residual pulsatile blood flow. There was no difference in the CRT: median 1.8 (IQR, 1.06-2.875) in 400 mm Hg vs median 1.87 (IQR, 1.25-2.8325) in 500 mm Hg, P = 0.81. The variance of CRT was significantly larger in 400 mm Hg: 2.99 in 400 mm Hg vs. 1.35 in 500 mm Hg, P = 0.02, Levene's test. Intraclass correlation coefficient for automated CRT was 0.56 at 400 mm Hg and 0.78 at 500 mm Hg. CONCLUSIONS: Using clinician CRT measurement data, we determined either 400 or 500 mm Hg is an appropriate pressure for automated CRT, although 500 mm Hg demonstrates superior consistency.

OBJECTIVES: Information obtained from point-of-care ultrasound during cardiopulmonary arrest and resuscitation (POCUS-CA) can be used to identify underlying pathophysiology and provide life-sustaining interventions. However, integration of POCUS-CA into resuscitation care is inconsistent. We used expert consensus building methodology to help identify discrete barriers to clinical integration. We subsequently applied implementation science frameworks to generate generalizable strategies to overcome these barriers. MEASURES AND MAIN RESULTS: Two multidisciplinary expert working groups used KJ Reverse-Merlin consensus building method to identify and characterize barriers contributing to failed POCUS-CA utilization in a hypothetical future state. Identified barriers were organized into affinity groups. The Center for Implementation Research (CFIR) framework and Expert Recommendations for Implementing Change (CFIR-ERIC) tool were used to identify strategies to guide POCUS-US implementation. RESULTS: Sixteen multidisciplinary resuscitation content experts participated in the working groups and identified individual barriers, consolidated into 19 unique affinity groups that mapped 12 separate CFIR constructs, representing all 5 CFIR domains. The CFIR-ERIC tool identified the following strategies as most impactful to address barriers described in the affinity groups: identify and prepare champions, conduct local needs assessment, conduct local consensus discussions, and conduct educational meetings. CONCLUSIONS: KJ Reverse-Merlin consensus building identified multiple barriers to implementing POCUS-CA. Implementation science methodologies identified and prioritized strategies to overcome barriers and guide POCUS-CA implementation across diverse clinical settings.

OBJECTIVES: To inform development of a preintubation checklist for pediatric emergency departments via multicenter usability testing of a prototype checklist. METHODS: This was a prospective, mixed methods study across 7 sites in the National Emergency Airway Registry for Pediatric Emergency Medicine (NEAR4PEM) collaborative. Pediatric emergency medicine attending physicians and senior fellows at each site were first oriented to a checklist prototype, including content previously identified using a modified Delphi approach. Each site used the checklist in 2 simulated cases: an "easy airway" and a "difficult airway" scenario. Facilitators recorded verbalization, completion, and timing of checklist items. After each simulation, participants completed an anonymous usability survey. Structured debriefings were used to gather additional feedback on checklist usability. Comments from the surveys and debriefing were qualitatively analyzed using a framework approach. Responses informed human factors-based optimization of the checklist. RESULTS: Fifty-five pediatric emergency medicine physicians/fellows (4-13 per site) participated. Participants found the prototype checklist to be helpful, easy to use, clear, and of appropriate length. During the simulations, 93% of checklist items were verbalized and more than 80% were completed. Median time to checklist completion was 6.2 minutes (interquartile range, 4.8-7.1) for the first scenario and 4.2 minutes (interquartile range, 2.7-5.8) for the second. Survey and debriefing data identified the following strengths: facilitating a shared mental model, cognitively offloading the team leader, and prompting contingency planning. Suggestions for checklist improvement included clarifying specific items, providing more detailed prompts, and allowing institution-specific customization. Integration of these data with human factors heuristic inspection resulted in a final checklist. CONCLUSIONS: Simulation-based, human factors usability testing of the National Emergency Airway Registry for Pediatric Emergency Medicine Preintubation Checklist allowed optimization prior to clinical implementation. Next steps involve integration into real-world settings utilizing rigorous implementation science strategies, with concurrent evaluation of the impact on patient outcomes and safety.

OBJECTIVES: To evaluate implementation of a video laryngoscope (VL) as a coaching device to reduce adverse tracheal intubation associated events (TIAEs). DESIGN: Prospective multicenter interventional quality improvement study. SETTING: Ten PICUs in North America. PATIENTS: Patients undergoing tracheal intubation in the PICU. INTERVENTIONS: VLs were implemented as coaching devices with standardized coaching language between 2016 and 2020. Laryngoscopists were encouraged to perform direct laryngoscopy with video images only available in real-time for experienced supervising clinician-coaches. MEASUREMENTS AND MAIN RESULTS: The primary outcome was TIAEs. Secondary outcomes included severe TIAEs, severe hypoxemia (oxygen saturation < 80%), and first attempt success. Of 5,060 tracheal intubations, a VL was used in 3,580 (71%). VL use increased from baseline (29.7%) to implementation phase (89.4%; p < 0.001). VL use was associated with lower TIAEs (VL 336/3,580 [9.4%] vs standard laryngoscope [SL] 215/1,480 [14.5%]; absolute difference, 5.1%; 95% CI, 3.1-7.2%; p < 0.001). VL use was associated with lower severe TIAE rate (VL 3.9% vs SL 5.3%; p = 0.024), but not associated with a reduction in severe hypoxemia (VL 15.7% vs SL 16.4%; p = 0.58). VL use was associated with higher first attempt success (VL 71.8% vs SL 66.6%; p < 0.001). In the primary analysis after adjusting for site clustering, VL use was associated with lower adverse TIAEs (odds ratio [OR], 0.61; 95% CI, 0.46-0.81; p = 0.001). In secondary analyses, VL use was not significantly associated with severe TIAEs (OR, 0.72; 95% CI, 0.44-1.19; p = 0.20), severe hypoxemia (OR, 0.95; 95% CI, 0.73-1.25; p = 0.734), or first attempt success (OR, 1.28; 95% CI, 0.98-1.67; p = 0.073). After further controlling for patient and provider characteristics, VL use was independently associated with a lower TIAE rate (adjusted OR, 0.65; 95% CI, 0.49-0.86; p = 0.003). CONCLUSIONS: Implementation of VL-assisted coaching achieved a high level of adherence across the PICUs. VL use was associated with reduced adverse TIAEs.

STUDY OBJECTIVE: To explore the association between video-assisted laryngoscopy (use of a videolaryngoscope regardless of where laryngoscopists direct their gaze), first-attempt success, and adverse airway outcomes. METHODS: We conducted an observational study using data from 2 airway consortiums that perform prospective surveillance: the National Emergency Airway Registry for Children (NEAR4KIDS) and a pediatric emergency medicine airway education collaborative. Data collected included patient and procedural characteristics and procedural outcomes. We performed multivariable analyses of the association of video-assisted laryngoscopy with individual patient outcomes and evaluated the association between site-level video-assisted laryngoscopy use and tracheal intubation outcomes. RESULTS: The study cohort included 1,412 tracheal intubation encounters performed from January 2017 to March 2021 across 11 participating sites. Overall, the first-attempt success was 70.0%. Video-assisted laryngoscopy was associated with increased odds of first-attempt success (odds ratio [OR] 2.01; 95% confidence interval [CI], 1.48 to 2.73) and decreased odds of severe adverse airway outcomes (OR 0.70; 95% CI, 0.58 to 0.85) including decreased severe hypoxia (OR 0.69; 95% CI, 0.55 to 0.87). Sites varied substantially in the use of video-assisted laryngoscopy (range from 12.9% to 97.8%), and sites with high use of video-assisted laryngoscopy (> 80%) experienced increased first-attempt success even after adjusting for individual patient laryngoscope use (OR 2.30; 95% CI, 1.79 to 2.95). CONCLUSION: Video-assisted laryngoscopy is associated with increased first-attempt success and fewer adverse airway outcomes for patients intubated in the pediatric emergency department. There is wide variability in the use of video-assisted laryngoscopy, and the high use is associated with increased odds of first-attempt success.

BACKGROUND: Determine if apneic oxygenation (AO) delivered via nasal cannula during the apneic phase of tracheal intubation (TI), reduces adverse TI-associated events (TIAEs) in children. METHODS: AO was implemented across 14 pediatric intensive care units as a quality improvement intervention during 2016-2020. Implementation consisted of an intubation safety checklist, leadership endorsement, local champion, and data feedback to frontline clinicians. Standardized oxygen flow via nasal cannula for AO was as follows: 5 L/min for infants (< 1 year), 10 L/min for young children (1-7 years), and 15 L/min for older children (≥ 8 years). Outcomes were the occurrence of adverse TIAEs (primary) and hypoxemia (SpO2 < 80%, secondary). RESULTS: Of 6549 TIs during the study period, 2554 (39.0%) occurred during the pre-implementation phase and 3995 (61.0%) during post-implementation phase. AO utilization increased from 23 to 68%, p < 0.001. AO was utilized less often when intubating infants, those with a primary cardiac diagnosis or difficult airway features, and patient intubated due to respiratory or neurological failure or shock. Conversely, AO was used more often in TIs done for procedures and those assisted by video laryngoscopy. AO utilization was associated with a lower incidence of adverse TIAEs (AO 10.5% vs. without AO 13.5%, p < 0.001), aOR 0.75 (95% CI 0.58-0.98, p = 0.03) after adjusting for site clustering (primary analysis). However, after further adjusting for patient and provider characteristics (secondary analysis), AO utilization was not independently associated with the occurrence of adverse TIAEs: aOR 0.90, 95% CI 0.72-1.12, p = 0.33 and the occurrence of hypoxemia was not different: AO 14.2% versus without AO 15.2%, p = 0.43. CONCLUSION: While AO use was associated with a lower occurrence of adverse TIAEs in children who required TI in the pediatric ICU after accounting for site-level clustering, this result may be explained by differences in patient, provider, and practice factors. Trial Registration Trial not registered.

OBJECTIVES: Mechanically ventilated children post-hematopoietic cell transplant (HCT) have increased morbidity and mortality compared with other mechanically ventilated critically ill children. Tracheal intubation-associated adverse events (TIAEs) and peri-intubation hypoxemia universally portend worse outcomes. We investigated whether adverse peri-intubation associated events occur at increased frequency in patients with HCT compared with non-HCT oncologic or other PICU patients and therefore might contribute to increased mortality. DESIGN: Retrospective cohort between 2014 and 2019. SETTING: Single-center academic noncardiac PICU. PATIENTS: Critically ill children who underwent tracheal intubation (TI). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data from the local airway management quality improvement databases and Virtual Pediatric Systems were merged. These data were supplemented with a retrospective chart review for HCT-related data, including HCT indication, transplant-related comorbidity status, and patient condition at the time of TI procedure. The primary outcome was defined as the composite of hemodynamic TIAE (hypo/hypertension, arrhythmia, cardiac arrest) and/or peri-intubation hypoxemia (oxygen saturation < 80%) events. One thousand nine hundred thirty-one encounters underwent TI, of which 92 (4.8%) were post-HCT, while 319 (16.5%) had history of malignancy without HCT, and 1,520 (78.7%) had neither HCT nor malignancy. Children post-HCT were older more often had respiratory failure as an indication for intubation, use of catecholamine infusions peri-intubation, and use of noninvasive ventilation prior to intubation. Hemodynamic TIAE or peri-intubation hypoxemia were not different across three groups (HCT 16%, non-HCT with malignancy 10%, other 15). After adjusting for age, difficult airway feature, provider type, device, apneic oxygenation use, and indication for intubation, we did not identify an association between HCT status and the adverse TI outcome (odds ratio, 1.32 for HCT status vs other; 95% CI, 0.72-2.41; p = 0.37). CONCLUSIONS: In this single-center study, we did not identify an association between HCT status and hemodynamic TIAE or peri-intubation hypoxemia during TI.

BACKGROUND: Ketamine has traditionally been avoided as an induction agent for tracheal intubation in patients with neurologic conditions at risk for intracranial hypertension due to conflicting data in the literature. The objective of this study was to evaluate and compare the effects of ketamine versus other medications as the primary induction agent on peri-intubation neurologic, hemodynamic and respiratory associated events in pediatric patients with neurologic conditions at risk for intracranial hypertension. METHODS: This retrospective observational study enrolled patients < 18 years of age at risk for intracranial hypertension who were admitted to a quaternary children's hospital between 2015 and 2020. Associated events included neurologic, hemodynamic and respiratory outcomes comparing primary induction agents of ketamine versus non-ketamine for tracheal intubation. RESULTS: Of 143 children, 70 received ketamine as the primary induction agent prior to tracheal intubation. Subsequently after tracheal intubation, all the patients received adjunct analgesic and sedative medications (fentanyl, midazolam, and/or propofol) at doses that were inadequate to induce general anesthesia but would keep them comfortable for further diagnostic workup. There were no significant differences between associated neurologic events in the ketamine versus non-ketamine groups (p = 0.42). This included obtaining an emergent computed tomography scan (p = 0.28), an emergent trip to the operating room within 5 h of tracheal intubation (p = 0.6), and the need for hypertonic saline administration within 15 min of induction drug administration for tracheal intubation (p = 0.51). There were two patients who had clinical and imaging evidence of herniation, which was not more adversely affected by ketamine compared with other medications (p = 0.49). Of the 143 patients, 23 had pre-intubation and post-intubation intracranial pressure values recorded; 11 received ketamine, and 3 of these patients had intracranial hypertension that resolved or improved, whereas the remaining 8 children had intracranial pressure within the normal range that was not exacerbated by ketamine. There were no significant differences in overall associated hemodynamic or respiratory events during tracheal intubation and no 24-h mortality in either group. CONCLUSIONS: The administration of ketamine as the primary induction agent prior to tracheal intubation in combination with other agents after tracheal intubation in children at risk for intracranial hypertension was not associated with an increased risk of peri-intubation associated neurologic, hemodynamic or respiratory events compared with those who received other induction agents.

BACKGROUND: Airway management checklists have improved paediatric patient safety in some clinical settings, but consensus on the appropriate components to include on a checklist for paediatric tracheal intubation in the ED is lacking. METHODS: A multidisciplinary panel of 14 experts in airway management within and outside of paediatric emergency medicine participated in a modified Delphi approach to develop consensus on the appropriate components for a paediatric airway management checklist for the ED. Panel members reviewed, modified and added to the components from the National Emergency Airway Registry for Children airway safety checklist for paediatric intensive care units using a 9-point appropriateness scale. Components with a median score of 7.0-9.0 and a 25th percentile score ≥7.0 achieved consensus for inclusion. A priori, the modified Delphi method was limited to a maximum of two rounds for consensus on essential components and one additional round for checklist creation. RESULTS: All experts participated in both rounds. Consensus was achieved on 22 components. Twelve were original candidate items and 10 were newly suggested or modified items. Consensus components included the following categories: patient assessment and plan (5 items), patient preparation (5 items), pharmacy (2 items), equipment (7 items) and personnel (3 items). The components were formatted into a 17-item clinically usable checklist. CONCLUSIONS: Using the modified Delphi method, consensus was established among airway management experts around essential components for an airway management checklist intended for paediatric tracheal intubation in the ED.

OBJECTIVE: It is not clear whether video laryngoscopy (VL) is associated with a higher first-pass success rate in pediatric patients with limited neck mobility when compared with direct laryngoscopy (DL). We sought to determine the association between the laryngoscopy method and first-pass success. METHODS: In this retrospective cohort study, we examined intubation data extracted from 2 prospectively collected, multicenter, airway management safety databases (National Emergency Airway Registry and the National Emergency Airway Registry for children), obtained during the years 2013-2018 in the emergency department. Intubations were included if patients were aged younger than 18 and had limited neck mobility. We compared first-pass success rates for ED intubations that were performed using VL versus DL. We built a structural causal model to account for potential confounders such as age, disease category (medical or trauma condition), other difficult airway characteristics, use of sedatives/paralytics, and laryngoscopist training level. We also analyzed adverse events as a secondary outcome. RESULTS: Of 34,239 intubations (19,071 in the National Emergency Airway Registry and 15,168 in the National Emergency Airway Registry for children), a total of 341 intubations (1.0%) met inclusion criteria; 168 were performed via VL and 173 were performed via DL. The median age of patients was 124 months (interquartile range, 48-204). There was no difference in first-pass success between VL and DL (79.8% vs 75.7%, P = 0.44). Video laryngoscopy was not associated with higher first-pass success (odds ratio, 1.11; 95% confidence interval 0.84-1.47, with DL as a comparator) when a structural causal model was used to account for confounders. There was no difference in the adverse events between VL and DL groups (13.7% vs 8.7%, P = 0.19). CONCLUSION: In children with limited neck mobility receiving tracheal intubation in the ED, neither VL nor DL was associated with a higher first-pass success rate.
RESUMEN
OBJECTIVES: To determine the association between preintubation respiratory support and outcomes in patients with acute respiratory failure and to determine the impact of immunocompromised (IC) diagnoses on outcomes after adjustment for illness severity. DESIGN: Retrospective multicenter cohort study. SETTING: Eighty-two centers in the Virtual Pediatric Systems database. PATIENTS: Children 1 month to 17 years old intubated in the PICU who received invasive mechanical ventilation (IMV) for greater than or equal to 24 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: High-flow nasal cannula (HFNC) or noninvasive positive-pressure ventilation (NIPPV) or both were used prior to intubation in 1,825 (34%) of 5,348 PICU intubations across 82 centers. When stratified by IC status, 50% of patients had no IC diagnosis, whereas 41% were IC without prior hematopoietic cell transplant (HCT) and 9% had prior HCT. Compared with patients intubated without prior support, preintubation exposure to HFNC (adjusted odds ratio [aOR], 1.33; 95% CI, 1.10-1.62) or NIPPV (aOR, 1.44; 95% CI, 1.20-1.74) was associated with increased odds of PICU mortality. Within subgroups of IC status, preintubation respiratory support was associated with increased odds of PICU mortality in IC patients (HFNC: aOR, 1.50; 95% CI, 1.11-2.03; NIPPV: aOR, 1.76; 95% CI, 1.31-2.35) and HCT patients (HFNC: aOR, 1.75; 95% CI, 1.07-2.86; NIPPV: aOR, 1.85; 95% CI, 1.12-3.02) compared with IC/HCT patients intubated without prior respiratory support. Preintubation exposure to HFNC/NIPPV was not associated with mortality in patients without an IC diagnosis. Duration of HFNC/NIPPV greater than 6 hours was associated with increased mortality in IC HCT patients (HFNC: aOR, 2.41; 95% CI, 1.05-5.55; NIPPV: aOR, 2.53; 95% CI, 1.04-6.15) and patients compared HCT patients with less than 6-hour HFNC/NIPPV exposure. After adjustment for patient and center characteristics, both preintubation HFNC/NIPPV use (median, 15%; range, 0-63%) and PICU mortality varied by center. CONCLUSIONS: In IC pediatric patients, preintubation exposure to HFNC and/or NIPPV is associated with increased odds of PICU mortality, independent of illness severity. Longer duration of exposure to HFNC/NIPPV prior to IMV is associated with increased mortality in HCT patients.

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.

STUDY OBJECTIVE: We sought to describe the tracheal intubation technique across a network of children's hospitals and explore the association between intubation technical adjuncts and first-attempt success as well as between laryngoscopy duration and the incidence of hypoxemia. METHODS: We conducted a prospective observational study in 4 tertiary pediatric emergency departments of the Videography in Pediatric Resuscitation Collaborative. Children undergoing tracheal intubation captured on video were eligible for inclusion. Data on intubator background, patient characteristics, technical characteristics (eg, use of videolaryngoscopy and apneic oxygenation), and procedural outcomes were obtained through a video review. RESULTS: We obtained complete data on first attempts in 494 patients. The first-attempt success rate was 67%, the median laryngoscopy duration was 35 seconds (interquartile range 25 to 40), and hypoxemia occurred in 15% of the patients. Videolaryngoscopy was used for at least a part of the procedure in 48% of the attempts, and it had no association with success or the incidence of hypoxemia. Attempts in which videolaryngoscopy was used for the entire procedure (compared with direct laryngoscopy for the entire procedure) had a longer duration (the difference between the medians was 6 seconds; 95% confidence interval, 1 to 12 seconds). Intubation attempts longer than 45 seconds had a greater incidence of hypoxemia (29% versus 6%). Furthermore, apneic oxygenation was used in 8% of the first attempts. CONCLUSION: Among children undergoing tracheal intubation in a group of pediatric emergency departments, first-attempt success occurred in 67% of the patients. Videolaryngoscopy use was associated with longer laryngoscopy durations but was not associated with success or the incidence of hypoxemia.

The Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network originated over 20 years ago to foster research to optimize the care of critically ill infants and children. Over this period, PALISI has seen two major evolutions: formalization of our network infrastructure and a broadening of our clinical research focus. First, the network is unique in that its activities and meetings are funded by subscriptions from members who now comprise a multidisciplinary group of investigators from over 90 PICUs all over the United States (US) and Canada, with collaborations across the globe. In 2020, the network converted into a standalone, nonprofit organizational structure (501c3), making the PALISI Network formally independent of academic and clinical institutions or professional societies. Such an approach allows us to invest in infrastructure and future initiatives with broader opportunities for fund raising. Second, our research investigations have expanded beyond the original focus on sepsis and acute lung injury, to incorporate the whole field of pediatric critical care, for example, efficient liberation from mechanical ventilator support, prudent use of blood products, improved safety of intubation practices, optimal sedation practices and glucose control, and pandemic research on influenza and COVID-19. Our network approach in each field follows, where necessary, the full spectrum of clinical and translational research, including: immunobiology studies for understanding basic pathologic mechanisms; surveys to explore contemporary clinical practice; consensus conferences to establish agreement about literature evidence; observational prevalence and incidence studies to measure scale of a clinical issue or question; case control studies as preliminary best evidence for design of definitive prospective studies; and, randomized controlled trials for informing clinical care. As a research network, PALISI and its related subgroups have published over 350 peer-reviewed publications from 2002 through September 2022.

BACKGROUND: Fluid administration in children undergoing surgery requires precision, however, determining fluid responsiveness can be challenging. Ultrasound has been used widely in the emergency department and intensive care units as a noninvasive, bedside manner of determining volume status, but the intraoperative period presents unique challenges as often the chest and abdomen are inaccessible for ultrasound. We investigate whether carotid artery ultrasound, specifically carotid flow time, can be used to determine fluid responsiveness in children under general anesthesia. METHODS: Prospective observational study of 87 children ages 1-12 years who were scheduled for elective noncardiac surgery. Ultrasound of the carotid artery and heart was performed at three time points: (1) after inhalational induction of anesthesia with the subject spontaneously breathing, (2) during positive pressure ventilation through endotracheal tube or supraglottic airway with tidal volume set at 8 ml/kg with PEEP of 10 cmH2 O, and (3) after a 10 ml/kg fluid bolus. Carotid flow time and cardiac output were measured from saved images. RESULTS: Corrected carotid flow time (FTc) increased with initiation of positive pressure ventilation in both fluid responders and nonresponders (352.7 vs. 365.3 msec, p = .005 in fluid responders; 348.3 vs. 365.2 msec, p = .001 in nonresponders). FTc increased after fluid bolus in both responders and nonresponders (365.3 vs. 397.6 msec, p < .001 in fluid responders; 365.2 vs. 397.2 msec, p < .001 in nonresponders). However, baseline FTc during spontaneous ventilation or positive pressure ventilation prior to fluid bolus was not associated with fluid responsiveness. DISCUSSION: Flow time increases with initiation of positive pressure ventilation and after administration of a fluid bolus. FTc may serve as an indicator of fluid status but does not predict fluid responsiveness in children under general anesthesia.
