Tracheal Intubation by Advanced Practice Registered Nurses in Pediatric Critical Care: Retrospective Study From the National Emergency Airway for Children Registry (2015-2019).

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.

Adverse Tracheal Intubation Events in Critically Ill Underweight and Obese Children: Retrospective Study of the National Emergency Airway for Children Registry (2013-2020).

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.

Relationship Distress at Home and Burnout Among 254 Pediatric Intensive Care Nurses.

OBJECTIVES: To assess the prevalence of relationship distress and burnout among PICU nurses. DESIGN: Cross-sectional, web-based survey. SETTING: Pediatric intensive care nursing practices in the United States. SUBJECTS: Pediatric intensive care nurses. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 254 pediatric intensive care nurses in the United States completed the survey consisting of demographic data, practice, and personal characteristics, Revised Dyadic Adjustment Scale, and modified Maslach Burnout Inventory. Relationship distress in consensus was noted in 45.6% of participants, and 26.3% reported distress in relationship satisfaction. Moderate to high burnout was reported by 65% nurses in the emotional exhaustion domain, 43% in depersonalization, and 27% of nurses reported low personal accomplishment. A significant difference in relationship satisfaction was found among nurses identified in different domains of burnout, showing that nurses who scored higher in depersonalization also reported higher distress in relationship satisfaction (p = 0.045). Interestingly, nurses who reported high personal accomplishment (thereby less burnout) reported higher distress in relationship consensus (p = 0.015). The difference in the satisfaction subscale between different age groups was significant, suggesting distress in satisfaction among nurses over the age of 40 (p = 0.004). Comparison of nurses actively involved in marriage counseling with those not actively involved in marriage counseling demonstrated a significant difference in relationship consensus (p = 0.046; odds ratio = 2.46; 95% CI, 0.99-6.06) and satisfaction (p = 0.004; odds ratio = 3.26; 95% CI, 1.42-7.47), suggesting an association between higher relationship distress and counseling. CONCLUSIONS: This study reflects the prevalence of relationship distress and its association with burnout and other practice and personal factors among PICU nurses. Nurses with high depersonalization experienced significantly higher distress in relationship satisfaction, and nurses who reported high personal satisfaction had significantly higher distress in relationship consensus.

Burnout and Psychological Distress Among Pediatric Critical Care Physicians in the United States.

OBJECTIVES: To estimate the prevalence of physician burnout, psychological distress, and its association with selected personal and practice characteristics among pediatric critical care physicians and to evaluate the relationship between burnout and psychological distress. DESIGN: Cross-sectional, online survey. SETTING: Pediatric critical care practices in the United States. SUBJECTS: Pediatric critical care physicians. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: A nonrandom sample of 253 physicians completed an online survey consisting of personal and practice characteristics, the Maslach Burnout Inventory, and the General Health Questionnaire. Nearly half of the participants (49%; 95% CI, 43-55%; n = 124) scored high burnout in at least one of the three subscales of the Maslach Burnout Inventory and 21% reported severe burnout. The risk of any burnout was about two times more in women physicians (odds ratio, 1.97; 95% CI, 1.2-3.4). Association between other personal or practice characteristics and burnout was not evident in this study, while regular physical exercise appeared to be protective. One third of all participants (30.5%) and 69% of those who experienced severe burnout screened positive for psychological distress. About 90% of the physicians reporting severe burnout have considered leaving their practice. CONCLUSIONS: Burnout is high among pediatric critical care physicians in the United States. About two thirds of the physicians with severe burnout met the screening criteria for psychological distress that suggests possible common mental disorders. Significant percentages of physicians experiencing burnout and considering to leave the profession has major implications for the critical care workforce.

End-Tidal Carbon Dioxide Use for Tracheal Intubation: Analysis From the National Emergency Airway Registry for Children (NEAR4KIDS) Registry.

OBJECTIVE: Waveform capnography use has been incorporated into guidelines for the confirmation of tracheal intubation. We aim to describe the trend in waveform capnography use in emergency departments and PICUs and assess the association between waveform capnography use and adverse tracheal intubation-associated events. DESIGN: A multicenter retrospective cohort study. SETTING: Thirty-four hospitals (34 ICUs and nine emergency departments) in the National Emergency Airway Registry for Children quality improvement initiative. PATIENTS: Primary tracheal intubation in children younger than 18 years. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patient, provider, and practice data for tracheal intubation procedure including a type of end-tidal carbon dioxide measurement, as well as the procedural safety outcomes, were prospectively collected. The use of waveform capnography versus colorimetry was evaluated in association with esophageal intubation with delayed recognition, cardiac arrest, and oxygen desaturation less than 80%. During January 2011 and December 2015, 9,639 tracheal intubations were reported. Waveform capnography use increased over time (39% in 2010 to 53% in 2015; p < 0.001), whereas colorimetry use decreased (< 0.001). There was significant variability in waveform capnography use across institutions (median 49%; interquartile range, 25-85%; p < 0.001). Capnography was used more often in emergency departments as compared with ICUs (66% vs. 49%; p < 0.001). The rate of esophageal intubation with delayed recognition was similar with waveform capnography versus colorimetry (0.39% vs. 0.46%; p = 0.62). The rate of cardiac arrest was also similar (p = 0.49). Oxygen desaturation occurred less frequently when capnography was used (17% vs. 19%; p = 0.03); however, this was not significant after adjusting for patient and provider characteristics. CONCLUSIONS: Significant variations existed in capnography use across institutions, with the use increasing over time in both emergency departments and ICUs. The use of capnography during intubation was not associated with esophageal intubation with delayed recognition or the occurrence of cardiac arrest.

Cricoid Pressure During Induction for Tracheal Intubation in Critically Ill Children: A Report From National Emergency Airway Registry for Children.

OBJECTIVES: Cricoid pressure is often used to prevent regurgitation during induction and mask ventilation prior to high-risk tracheal intubation in critically ill children. Clinical data in children showing benefit are limited. Our objective was to evaluate the association between cricoid pressure use and the occurrence of regurgitation during tracheal intubation for critically ill children in PICU. DESIGN: A retrospective cohort study of a multicenter pediatric airway quality improvement registry. SETTINGS: Thirty-five PICUs within general and children's hospitals (29 in the United States, three in Canada, one in Japan, one in Singapore, and one in New Zealand). PATIENTS: Children (< 18 yr) with initial tracheal intubation using direct laryngoscopy in PICUs between July 2010 and December 2015. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Multivariable logistic regression analysis was used to evaluate the association between cricoid pressure use and the occurrence of regurgitation while adjusting for underlying differences in patient and clinical care factors. Of 7,825 events, cricoid pressure was used in 1,819 (23%). Regurgitation was reported in 106 of 7,825 (1.4%) and clinical aspiration in 51 of 7,825 (0.7%). Regurgitation was reported in 35 of 1,819 (1.9%) with cricoid pressure, and 71 of 6,006 (1.2%) without cricoid pressure (unadjusted odds ratio, 1.64; 95% CI, 1.09-2.47; p = 0.018). On multivariable analysis, cricoid pressure was not associated with the occurrence of regurgitation after adjusting for patient, practice, and known regurgitation risk factors (adjusted odds ratio, 1.57; 95% CI, 0.99-2.47; p = 0.054). A sensitivity analysis in propensity score-matched cohorts showed cricoid pressure was associated with a higher regurgitation rate (adjusted odds ratio, 1.01; 95% CI, 1.00-1.02; p = 0.036). CONCLUSIONS: Cricoid pressure during induction and mask ventilation before tracheal intubation in the current ICU practice was not associated with a lower regurgitation rate after adjusting for previously reported confounders. Further studies are needed to determine whether cricoid pressure for specific indication with proper maneuver would be effective in reducing regurgitation events.

Clinical Impact of External Laryngeal Manipulation During Laryngoscopy on Tracheal Intubation Success in Critically Ill Children.

OBJECTIVES: External laryngeal manipulation is a commonly used maneuver to improve visualization of the glottis during tracheal intubation in children. However, the effectiveness to improve tracheal intubation attempt success rate in the nonanesthesia setting is not clear. The study objective was to evaluate the association between external laryngeal manipulation use and initial tracheal intubation attempt success in PICUs. DESIGN: A retrospective observational study using a multicenter emergency airway quality improvement registry. SETTING: Thirty-five PICUs within general and children's hospitals (29 in the United States, three in Canada, one in Japan, one in Singapore, and one in New Zealand). PATIENTS: Critically ill children (< 18 years) undergoing initial tracheal intubation with direct laryngoscopy in PICUs between July 1, 2010, and December 31, 2015. MEASUREMENTS AND MAIN RESULTS: Propensity score-matched analysis was performed to evaluate the association between external laryngeal manipulation and initial attempt success while adjusting for underlying differences in patient and clinical care factors: age, obesity, tracheal intubation indications, difficult airway features, provider training level, and neuromuscular blockade use. External laryngeal manipulation was defined as any external force to the neck during laryngoscopy. Of the 7,825 tracheal intubations, the initial tracheal intubation attempt was successful in 1,935/3,274 intubations (59%) with external laryngeal manipulation and 3,086/4,551 (68%) without external laryngeal manipulation (unadjusted odds ratio, 0.69; 95% CI, 0.62-0.75; p < 0.001). In propensity score-matched analysis, external laryngeal manipulation remained associated with lower initial tracheal intubation attempt success (adjusted odds ratio, 0.93; 95% CI, 0.90-0.95; p < 0.001). CONCLUSIONS: External laryngeal manipulation during direct laryngoscopy was associated with lower initial tracheal intubation attempt success in critically ill children, even after adjusting for underlying differences in patient factors and provider levels. The indiscriminate use of external laryngeal manipulation cannot be recommended.

Effect of Location on Tracheal Intubation Safety in Cardiac Disease-Are Cardiac ICUs Safer?

OBJECTIVES: Evaluate differences in tracheal intubation-associated events and process variances (i.e., multiple intubation attempts and oxygen desaturation) between pediatric cardiac ICUs and noncardiac PICUs in children with underlying cardiac disease. DESIGN: Retrospective cohort study using a multicenter tracheal intubation quality improvement database (National Emergency Airway Registry for Children). SETTING: Thirty-six PICUs (five cardiac ICUs, 31 noncardiac ICUs) from July 2012 to March 2016. PATIENTS: Children with medical or surgical cardiac disease who underwent intubation in an ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Our primary outcome was the rate of any adverse tracheal intubation-associated event. Secondary outcomes were severe tracheal intubation-associated events, multiple tracheal intubation attempt rates, and oxygen desaturation. There were 1,502 tracheal intubations in children with underlying cardiac disease (751 in cardiac ICUs, 751 in noncardiac ICUs) reported. Cardiac ICUs and noncardiac ICUs had similar proportions of patients with surgical cardiac disease. Patients undergoing intubation in cardiac ICUs were younger (median age, 1 mo [interquartile range, 0-6 mo]) compared with noncardiac ICUs (median 3 mo [interquartile range, 1-11 mo]; p < 0.001). Tracheal intubation-associated event rates were not different between cardiac ICUs and noncardiac ICUs (16% vs 19%; adjusted odds ratio, 0.74; 95% CI, 0.54-1.02; p = 0.069). However, in a sensitivity analysis comparing cardiac ICUs with mixed ICUs (i.e., ICUs caring for children with either general pediatric or cardiac diseases), cardiac ICUs had decreased odds of adverse events (adjusted odds ratio, 0.71; 95% CI, 0.52-0.97; p = 0.033). Rates of severe tracheal intubation-associated events and multiple attempts were similar. Desaturations occurred more often during intubation in cardiac ICUs (adjusted odds ratio, 1.61; 95% CI, 1.04-1.15; p = 0.002). CONCLUSIONS: In children with underlying cardiac disease, rates of adverse tracheal intubation-associated events were not lower in cardiac ICUs as compared to noncardiac ICUs, even after adjusting for differences in patient characteristics and care models.

Hemolytic uremic syndrome complicated by Clostridium septicum bacteremia and new-onset type 1 diabetes mellitus. Report of a case
.

We report the unusual case of a 5-year-old male hospitalized for management of diabetic ketoacidosis (DKA) and new-onset type 1 diabetes mellitus (T1DM) who developed acute renal injury secondary to hemolytic uremic syndrome (HUS). He was diagnosed with Shiga toxin-producing entero-hemorrhagic Escherichia coli (EHEC) 0157:H7-positive HUS 48 hours after being diagnosed with new-onset T1DM/DKA. His hospital course was complicated by Clostridium septicum sepsis with colonic perforation. This patient's diagnosis of new-onset T1DM just prior to HUS is novel. Furthermore, some cases of HUS and concurrent atraumatic C. septicum infection have been documented, but only two other survivor cases have been found, and no previous cases report of concurrent T1DM complicating atraumatic C. septicum infection have been documented so far. Aggressive surgical management and appropriate early antibiotic therapy may have been important for this child's survival.

Recurrent rhabdomyolysis in a teenager with psychosis-intermittent hyponatremia-polydipsia syndrome.

OBJECTIVE: To report a case of recurrent hyponatremia and rhabdomyolysis in a teenager with psychogenic polydipsia. CASE SUMMARY: A 16-year-old boy was admitted with recurrent episodes of hyponatremia and rhabdomyolysis secondary to psychogenic polydipsia. He was treated with hypertonic saline, intravenous fluids, and supportive care. DISCUSSION: Psychogenic polydipsia is a condition characterized by compulsive drinking. Severe hyponatremia is a rare, but serious complication in patients with psychogenic polydipsia. Failure in cell volume regulatory mechanisms, defective osmoregulation, defective urinary dilution, and enhanced secretion of vasopressin are believed to play a role in the development of hyponatremia. Rhabdomyolysis can complicate severe hyponatremia, although the exact mechanism is not known. Antipsychotic drugs are also implicated in rhabdomyolysis. CONCLUSIONS: Severe hyponatremia and rhabdomyolysis can complicate psychogenic polydipsia. Patients receiving antipsychotic drugs with concomitant severe hyponatremia need to be monitored for rhabdomyolysis.

Refractory hypotension from massive bupropion overdose successfully treated with extracorporeal membrane oxygenation.

An 11-month-old male infant presented with history of bupropion ingestion (750 mg/kg). He developed seizures, respiratory failure, and severe hypotension with metabolic acidosis refractory to inotropic support. The patient received mechanical ventilation, intralipids, phenytoin, inotropic support (dopamine, norepinephrine, and epinephrine), and extracorporeal membrane oxygenation (ECMO). Inotropes were weaned upon initiation of ECMO and discontinued 66 hours after ingestion. Total ECMO duration was 71 hours. The patient was extubated on hospital day 8 and has not had any neurological sequelae upon 12-month follow-up examinations. We report for the first time successful use of ECMO after ingestion of a potentially fatal dose of bupropion.

Family Presence During Pediatric Tracheal Intubations.

IMPORTANCE: Family-centered care, which supports family presence (FP) during procedures, is now a widely accepted standard at health care facilities that care for children. However, there is a paucity of data regarding the practice of FP during tracheal intubation (TI) in pediatric intensive care units (PICUs). Family presence during procedures in PICUs has been advocated. OBJECTIVE: To describe the current practice of FP during TI and evaluate the association with procedural and clinician (including physician, respiratory therapist, and nurse practitioner) outcomes across multiple PICUs. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study in which all TIs from July 2010 to March 2014 in the multicenter TI database (National Emergency Airway Registry for Children [NEAR4KIDS]) were analyzed. Family presence was defined as a family member present during TI. This study included all TIs in patients younger than 18 years in 22 international PICUs. EXPOSURES: Family presence and no FP during TI in the PICU. MAIN OUTCOMES AND MEASURES: The percentage of FP during TIs. First attempt success rate, adverse TI-associated events, multiple attempts (≥ 3), oxygen desaturation (oxygen saturation as measured by pulse oximetry <80%), and self-reported team stress level. RESULTS: A total of 4969 TI encounters were reported. Among those, 81% (n = 4030) of TIs had documented FP status (with/without). The median age of participants with FP was 2 years and 1 year for those without FP. The average percentage of TIs with FP was 19% and varied widely across sites (0%-43%; P < .001). Tracheal intubations with FP (vs without FP) were associated with older patients (median, 2 years vs 1 year; P = .04), lower Paediatric Index of Mortality 2 score, and pediatric resident as the first airway clinician (23%, n = 179 vs 18%, n = 584; odds ratio [OR], 1.4; 95% CI, 1.2-1.7). Tracheal intubations with FP and without FP were no different in the first attempt success rate (OR, 1.00; 95% CI, 0.85-1.18), adverse TI-associated events (any events: OR, 1.06; 95% CI, 0.85-1.30 and severe events: OR, 1.04; 95% CI, 0.75-1.43), multiple attempts (≥ 3) (OR, 1.03; 95% CI, 0.82-1.28), oxygen desaturation (oxygen saturation <80%) (OR, 0.97; 95% CI, 0.80-1.18), or self-reported team stress level (OR, 1.09; 95% CI, 0.92-1.31). This result persisted after adjusting for patient and clinician confounders. CONCLUSIONS AND RELEVANCE: Wide variability exists in FP during TIs across PICUs. Family presence was not associated with first attempt success, adverse TI-associated events, oxygen desaturation (<80%), or higher team stress level. Our data suggest that FP during TI can safely be implemented as part of a family-centered care model in the PICU.
