Item Extubation Readiness Practices and Barriers to Extubation in Pediatric Subjects(AARC, 2021-04) Krasinkiewicz, Johnny M.; Friedman, Matthew L.; Slaven, James E.; Lutfi, Riad; Abu-Sultaneh, Samer; Tori, Alvaro J.; Pediatrics, School of MedicineBACKGROUND: Invasive mechanical ventilation is a lifesaving intervention that is associated with short- and long-term morbidities. Extubation readiness protocols aim to decrease extubation failure rates and simultaneously shorten the duration of invasive ventilation. This study sought to analyze extubation readiness practices at one institution and identify barriers to extubation in pediatric patients who have passed an extubation readiness test (ERT). METHODS: We performed a retrospective chart review of all pediatric subjects admitted between April 2017 and March 2018, and who were on mechanical ventilation. Exclusion criteria were cardiac ICU admission, tracheostomy, chronic ventilator support, limited resuscitation status, and death before extubation attempt. Data with regard to the method of ERT and reasons for delaying extubation were collected. RESULTS: There were 427 subjects included in the analysis with 69% having had an ERT before extubation. Of those, 39% were extubated per our daily spontaneous breathing trial (SBT) protocol, and the daily SBT failed in 30% but they had passed a subsequent pressure support and CPAP trial on the same day. The most common reasons for failing the daily SBT were a lack of spontaneous breathing (30% [75/252]), being intubated < 24 h (24% [60/252]), breathing frequency outside the target range (22% [55/252]), and not meeting tidal volume goal (14% [34/252]). The most common documented reasons for delaying extubation despite passing daily SBT were planned procedure (29% [26/90]), neurologic status (23% [21/90]), and no leak around the endotracheal tube (18% [16/90]). The median time between passing ERT and extubation was 7 h (interquartile range, 5–10). CONCLUSIONS: In our institution, there was variation in extubation readiness practices that could lead to a significant delay in liberation from invasive ventilation. Adjustment of our daily SBT to tolerate a higher work of breathing, such as higher breathing frequencies and lower tidal volumes, and incorporating sedation scoring into the protocol could be made without significantly affecting extubation failure rates.Item Food Protein-Induced Enterocolitis Syndrome Causing Hypovolemic Shock and Methemoglobinemia(Hindawi, 2018-04-30) Malin, Stefan W.; Lutfi, Riad; Friedman, Matthew L.; Teagarden, Alicia M.; Pediatrics, School of MedicineA 5-week-old previously healthy male presented with vomiting and diarrhea leading to hypovolemic shock and profound metabolic acidosis. He was subsequently found to have severe methemoglobinemia. The acidosis and shock improved with fluid resuscitation and methemoglobinemia was successfully treated with methylene blue. An extensive workup, including evaluations for infectious and metabolic etiologies, was unremarkable. However, a detailed dietary history revealed a recent change in diet, supporting a diagnosis of food protein-induced enterocolitis syndrome (FPIES). We present this case to highlight the importance of considering FPIES in an infant with vomiting and diarrhea, in the setting of a recent dietary change, leading to profound dehydration, metabolic acidosis, and methemoglobinemia. Diagnosis of FPIES, although difficult to make and one of exclusion, can be potentially life-saving.Item Impact of an untrained CPR Coach in simulated pediatric cardiopulmonary arrest: A pilot study(Elsevier, 2020-12-01) Badke, Colleen M.; Friedman, Matthew L.; Harris, Z. Leah; McCarthy-Kowols, Maureen; Tran, Sifrance; Pediatrics, School of MedicineAim To determine if an untrained cardiopulmonary resuscitation (CPR) Coach, with no access to real-time CPR feedback technology, improves CPR quality. Methods This was a prospective randomized pilot study at a tertiary care children's hospital that aimed to integrate an untrained CPR Coach into resuscitation teams during simulated pediatric cardiac arrest. Simulation events were randomized to two arms: control (no CPR Coach) or intervention (CPR Coach). Simulations were run by pediatric intensive care unit (PICU) providers and video recorded. Scenarios focused on full cardiopulmonary arrest; neither team had access to real-time CPR feedback technology. The primary outcome was CPR quality. Secondary outcomes included workload assessments of the team leader and CPR Coach using the NASA Task Load Index and perceptions of CPR quality. Results Thirteen simulations were performed; 5 were randomized to include a CPR Coach. There was a significantly shorter duration to backboard placement in the intervention group (median 20s [IQR 0–27s] vs. 52s [IQR 38–65s], p=0.02). There was no self-reported change in the team leader's workload between scenarios using a CPR Coach compared to those without a CPR Coach. There were no significant changes in subjective CPR quality measures. Conclusions In this pilot study, inclusion of an untrained CPR Coach during simulated CPR shortened time to backboard placement but did not improve most metrics of CPR quality or significantly affect team leader workload. More research is needed to better assess the value of a CPR Coach and its potential impact in real-world resuscitation.Item Multi-Lobar Atelectasis in Children Receiving Venoarterial Extracorporeal Membrane Oxygenation for Cardiac Indications(Daedalus, 2022-11-15) Nader, Maria Abou; Friedman, Matthew L.; Mastropietro, Christopher W.; Pediatrics, School of MedicineBackground: Respiratory complications are common in patients who require venoarterial (VA) extracorporeal membrane oxygenation (ECMO) for cardiac indications. We aimed to examine the frequency and characteristics of patients who develop multi-lobar atelectasis early in the course of VA ECMO and to identify factors associated with its occurrence. Methods: We performed a single-center retrospective review of consecutive pediatric subjects on VA ECMO in the cardiovascular ICU from 2014 to 2019. Chest radiographs before VA ECMO initiation and daily for up to 5 d of VA ECMO support were reviewed. Multi-lobar atelectasis was defined as the collapse of ≥2 lobes of the same lung. Patients with multi-lobar atelectasis before or immediately after VA ECMO cannulation were excluded. Bivariate comparisons and multivariable logistic regression analyses were performed to identify factors independently associated with lung collapse. Results of the multivariable analysis are provided as odds ratio (OR) with 95% CI. Results: We reviewed 119 VA ECMO runs in 101 unique subjects. Multi-lobar atelectasis occurred in 36 runs (30%), with an isolated collapse of the left lung occurring most frequently (no. runs = 20). VA ECMO runs complicated by multi-lobar atelectasis were significantly longer and associated with lower hospital survival (51% vs 77%, survival in subjects without multi-lobar atelectasis; P = .01). Multivariable logistic regression analysis identified a subsequent ECMO run during the same admission to be independently associated with multi-lobar atelectasis (OR 5.4, 95% CI 1.2-21.5). Subanalysis of the subjects with isolated left lung collapse revealed male sex (OR 8.9, 95% CI 1.6-48.2) and subsequent ECMO run during the same admission (OR 4.0, 95% CI 1.2-13.6) to be independently associated with this complication, and mechanical ventilation at least 12 h before ECMO may be protective (OR 0.22, 95% CI 0.07-0.76). Conclusions: Multi-lobar atelectasis commonly occurred in children who were receiving VA ECMO for cardiac failure and was associated with worse outcomes. Male patients, a subsequent VA ECMO run during the same hospitalization, and patients in whom mechanical ventilation was initiated shortly before ECMO cannulation may be at increased risk for this complication.Item Neurological and Psychological Sequelae Associated With Multisystem Inflammatory Syndrome in Children(American Medical Association, 2023-07-03) Rollins, Caitlin K.; Calderon, Johanna; Wypij, David; Taylor, Alex M.; Kanjiker, Tahera Sultana Davalji; Rohde, Julia S.; Maiman, Moshe; Zambrano, Laura D.; Newhams, Margaret M.; Rodriguez, Susan; Hart, Nicholas; Worhach, Jennifer; Kucukak, Suden; Poussaint, Tina Y.; Son, Mary Beth F.; Friedman, Matthew L.; Gertz, Shira J.; Hobbs, Charlotte V.; Kong, Michele; Maddux, Aline B.; McGuire, Jennifer L.; Licht, Paul A.; Allen Staat, Mary; Yonker, Lael M.; Mazumdar, Maitreyi; Randolph, Adrienne G.; Campbell, Angela P.; Newburger, Jane W.; Overcoming COVID-19 Investigators; Pediatrics, School of MedicineImportance: Acute neurological involvement occurs in some patients with multisystem inflammatory syndrome in children (MIS-C), but few data report neurological and psychological sequelae, and no investigations include direct assessments of cognitive function 6 to 12 months after discharge. Objective: To characterize neurological, psychological, and quality of life sequelae after MIS-C. Design, setting, and participants: This cross-sectional cohort study was conducted in the US and Canada. Participants included children with MIS-C diagnosed from November 2020 through November 2021, 6 to 12 months after hospital discharge, and their sibling or community controls, when available. Data analysis was performed from August 2022 to May 2023. Exposure: Diagnosis of MIS-C. Main outcomes and measures: A central study site remotely administered a onetime neurological examination and in-depth neuropsychological assessment including measures of cognition, behavior, quality of life, and daily function. Generalized estimating equations, accounting for matching, assessed for group differences. Results: Sixty-four patients with MIS-C (mean [SD] age, 11.5 [3.9] years; 20 girls [31%]) and 44 control participants (mean [SD] age, 12.6 [3.7] years; 20 girls [45%]) were enrolled. The MIS-C group exhibited abnormalities on neurological examination more frequently than controls (15 of 61 children [25%] vs 3 of 43 children [7%]; odds ratio, 4.7; 95% CI, 1.3-16.7). Although the 2 groups performed similarly on most cognitive measures, the MIS-C group scored lower on the National Institutes of Health Cognition Toolbox List Sort Working Memory Test, a measure of executive functioning (mean [SD] scores, 96.1 [14.3] vs 103.1 [10.5]). Parents reported worse psychological outcomes in cases compared with controls, particularly higher scores for depression symptoms (mean [SD] scores, 52.6 [13.1] vs 47.8 [9.4]) and somatization (mean [SD] scores, 55.5 [15.5] vs 47.0 [7.6]). Self-reported (mean [SD] scores, 79.6 [13.1] vs 85.5 [12.3]) and parent-reported (mean [SD] scores, 80.3 [15.5] vs 88.6 [13.0]) quality of life scores were also lower in cases than controls. Conclusions and relevance: In this cohort study, compared with contemporaneous sibling or community controls, patients with MIS-C had more abnormal neurologic examinations, worse working memory scores, more somatization and depression symptoms, and lower quality of life 6 to 12 months after hospital discharge. Although these findings need to be confirmed in larger studies, enhanced monitoring may be warranted for early identification and treatment of neurological and psychological symptoms.Item Open abdomen during extracorporeal membrane oxygenation is a safe and effective treatment for abdominal compartment syndrome(Elsevier, 2022-09) Brown, Joshua; Warnock, Brielle; Turk, Eamaan; Hobson, Michael J.; Friedman, Matthew L.; Gray, Brian W.; Surgery, School of MedicineBACKGROUND/PURPOSE: Decompressive laparotomy and open abdomen for abdominal compartment syndrome have been historically avoided during Extracorporeal Membrane Oxygenation (ECMO) due to seemingly elevated risks of bleeding and infection. Our goal was to evaluate a cohort of pediatric respiratory ECMO patients who underwent decompressive laparotomy with open abdomen at a single institution and to compare these patients to ECMO patients without open abdomen. METHODS: We reviewed all pediatric respiratory ECMO (30 days-18 years) patients treated with decompressive laparotomy with open abdomen at Riley Hospital for Children (1/2000-12/2019) and compared these patients to concurrent respiratory ECMO patients with closed abdomen. We excluded patients with surgical cardiac disease. We assessed demographics, ECMO data, and outcomes and defined significance as p = 0.05. RESULTS: 6 of 81 ECMO patients were treated with decompressive laparotomy and open abdomen. Open and closed abdomen groups had similar age (p = 0.223) and weight (0.286) at cannulation, but the open abdomen group had a higher reliance on vasoactive medications (Vasoactive Inotropic Score, p = 0.040). Open abdomen group survival was similar to closed abdomen patients (66.7%, vs 62.7%, p = 1). Open abdomen patients had lower incidence of ECMO complications (33.3% vs 83.6%, p = 0.014), but the groups had similar bleeding complications (p = 0.412) and PRBC transfusion volume (p = 0.941). CONCLUSION/IMPACT: Pediatric ECMO patients with open abdomen after decompressive laparotomy had similar survival, blood products administered, and complications as those with a closed abdomen. An open abdomen is not a contra-indication to ECMO support in pediatric respiratory patients and should be considered in select patients.Item Progression of Respiratory Support Following Pediatric Extubation(Wolters Kluwer, 2020-12) Krasinkiewicz, Johnny M.; Friedman, Matthew L.; Slaven, James E.; Tori, Alvaro J.; Lutfi, Riad; Abu-Sultaneh, Samer; Pediatrics, School of MedicineObjectives: High-flow nasal cannula and noninvasive positive pressure ventilation have become ubiquitous in contemporary PICUs. Practice patterns associated with the use of these modalities have not been well described. In this study, we aimed to describe the use of high-flow nasal cannula and noninvasive positive pressure ventilation in children after extubation and analyze the progression of usage in association with patient factors. Our secondary aim was to describe interventions used for postextubation stridor. Design: Single-center retrospective cohort study. Setting: A 36-bed quaternary medical-surgical PICU. Patients: Mechanically ventilated pediatric patients admitted between April 2017 and March 2018. Exclusions were patients in the cardiac ICU, patients requiring a tracheostomy or chronic ventilatory support, and patients with limited resuscitation status. Interventions: None. Measurements and Main Results: Data regarding respiratory modality use was collected for the first 72 hours after extubation. There were 427 patients included in the analysis; 51 patients (11.9%) were extubated to room air, 221 (51.8%) to nasal cannula, 132 (30.9%) to high-flow nasal cannula, and 23 (5.4%) to noninvasive positive pressure ventilation. By 72 hours, 314 patients (73.5%) were on room air, 52 (12.2%) on nasal cannula, 29 (6.8%) on high-flow nasal cannula, eight (1.9%) on noninvasive positive pressure ventilation, and 24 (5.6%) were reintubated. High-flow nasal cannula was the most used respiratory modality for postextubation stridor. Multivariate analysis demonstrated that longer duration of invasive mechanical ventilation increased the odds of initial high-flow nasal cannula and noninvasive positive pressure ventilation use, and a diagnosis of cerebral palsy increased the odds of escalating from high-flow nasal cannula to noninvasive positive pressure ventilation in the first 24 hours post extubation. Conclusions: High-flow nasal cannula is commonly used immediately after pediatric extubation and the development of postextubation stridor; however, its usage sharply declines over the following 72 hours. Larger multicenter trials are needed to identify high-risk patients for extubation failure that might benefit the most from prophylactic use of high-flow nasal cannula and noninvasive positive pressure ventilation after extubation.Item Tracheostomy and Long-Term Mechanical Ventilation in Children after Veno-Venous Extracorporeal Membrane Oxygenation(Wiley, 2021-09) Mallory, Palen P.; Barbaro, Ryan P.; Bembea, Melania M.; Bridges, Brian C.; Chima, Ranjit S.; Kilbaugh, Todd J.; Potera, Renee M.; Rosner, Elizabeth A.; Sandhu, Hitesh S.; Slaven, James E.; Tarquinio, Keiko M.; Cheifetz, Ira M.; Friedman, Matthew L.; Biostatistics, School of Public HealthObjective 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 to 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 work informs anticipatory guidance provided to families of patients requiring prolonged respiratory ECMO support, and lays the foundation for future research.

Knowledge of tracheostomy practices and outcomes of ECMO-supported children who undergo tracheostomy on ECMO may inform decision-making. Design: Retrospective cohort study Setting: ECMO centers contributing to the Extracorporeal Life Support Organization (ELSO) Registry Patients: Children birth to 18 years who received ECMO support for 7 days or greater for respiratory failure from January 1st 2015 to December 31st 2019. Interventions: None Measurements and Main Results: 3685 children received at least seven days of ECMO support for respiratory failure. The median duration of ECMO support was 13.0 days (IQR 9.3-19.9), and in-hospital mortality was 38.7% (1426/3685). A tracheostomy was placed during ECMO support in 94/3685 (2.6%). Of those who received a tracheostomy on ECMO, the procedure was performed at a median 13.2 days (IQR 6.3-25.9) after initiation of ECMO. Surgical site bleeding was documented in 26% of children who received a tracheostomy (12% after tracheostomy placement). Among children who received a tracheostomy, the median duration of ECMO support was 24.2 days (IQR 13.0-58.7); in-hospital mortality was 30/94 (32%). Those that received a tracheostomy before 14 days on ECMO were older (median age 15.8 years (IQR 4.7-15.5) versus 11.7 years (IQR 11.5-17.3); p-value=0.002) and more likely to have been supported on VV-ECMO (84% vs 52%, p=0.001). Twenty-two percent (11/50) of those who received a tracheostomy before 14 days died in the hospital, compared to 19/44 (43%) of those who received a tracheostomy at 14 days or later (p=0.03). Conclusions: Tracheostomies during ECMO were uncommon in children. One in four patients who received a tracheostomy on ECMO had surgical site bleeding. Children who had tracheostomies placed after 14 days were younger and had worse outcomes, potentially representing tracheostomy as a “secondary” strategy for prolonged ECMO support.Item Veno-Venous Extracorporeal Membrane Oxygenation for Children With Cancer or Hematopoietic Cell Transplant: A Ten Center Cohort(Wolters Kluwer, 2021) Bridges, Brian C.; Kilbaugh, Todd J.; Barbaro, Ryan P.; Bembea, Melania M.; Chima, Ranjit S.; Potera, Renee M.; Rosner, Elizabeth A.; Sandhu, Hitesh S.; Slaven, James E.; Tarquinio, Keiko M.; Cheifetz, Ira M.; Rowan, Courtney M.; Friedman, Matthew L.; Biostatistics, School of Public HealthWe performed a multi-center retrospective cohort study of children aged 14 days to 18 years in the United States from 2011 to 2016 with cancer or hematopoietic cell transplant (HCT) who were supported with veno-venous extracorporeal membrane oxygenation (V-V ECMO). We compared the outcomes of children with oncological diagnoses or HCT supported with V-V ECMO to other children who have received V-V ECMO support. In this cohort of 204 patients supported with V-V ECMO, 30 (15%) had a diagnosis of cancer or a history of HCT. There were 21 patients who had oncological diagnoses without HCT and 9 children were post-HCT. The oncology/HCT group had a higher overall ICU mortality (67% vs. 28%, p<0.001), mortality on ECMO (43% vs 21%, p<0.01), and ICU mortality among ECMO survivors (35% vs 8%, p<0.01). The oncology/HCT group had a higher rate of conversion to veno-arterial (V-A) ECMO (23% vs. 9%, p=0.02) (RR 2.5, 95% CI 1.1–5.6). Children with cancer or HCT were older (6.6 years vs 2.9 years, p=0.02) and had higher creatinine levels (0.65 mg/dL vs 0.4 mg/dL, p=0.04) but were similar to the rest of the cohort for other pre-ECMO variables. For post-HCT patients, survival was significantly worse for those whose indication for HCT was cancer or immunodeficiency (0/6) as compared to other nonmalignant indications (3/3) (p=0.01).
