Item Association of Extubation Failure Rates With High-Flow Nasal Cannula, Continuous Positive Airway Pressure, and Bilevel Positive Airway Pressure vs Conventional Oxygen Therapy in Infants and Young Children: A Systematic Review and Network Meta-Analysis(American Medical Association, 2023-06-05) Iyer, Narayan Prabhu; Rotta, Alexandre T.; Essouri, Sandrine; Fioretto, Jose Roberto; Craven, Hannah J.; Whipple, Elizabeth C.; Ramnarayan, Padmanabhan; Abu-Sultaneh, Samer; Khemani, Robinder G.IMPORTANCE: Extubation failure (EF) has been associated with worse outcomes in critically ill children. The relative efficacy of different modes of noninvasive respiratory support (NRS) to prevent EF is unknown. OBJECTIVE: To study the reported relative efficacy of different modes of NRS (high-flow nasal cannula [HFNC], continuous positive airway pressure [CPAP], and bilevel positive airway pressure [BiPAP]) compared to conventional oxygen therapy (COT). DATA SOURCES: MEDLINE, Embase, and CINAHL Complete through May 2022. STUDY SELECTION: Randomized clinical trials that enrolled critically ill children receiving invasive mechanical ventilation for more than 24 hours and compared the efficacy of different modes of postextubation NRS. DATA EXTRACTION AND SYNTHESIS: Random-effects models were fit using a bayesian network meta-analysis framework. Between-group comparisons were estimated using odds ratios (ORs) or mean differences with 95% credible intervals (CrIs). Treatment rankings were assessed by rank probabilities and the surface under the cumulative rank curve (SUCRA). MAIN OUTCOMES AND MEASURES: The primary outcome was EF (reintubation within 48 to 72 hours). Secondary outcomes were treatment failure (TF, reintubation plus NRS escalation or crossover to another NRS mode), pediatric intensive care unit (PICU) mortality, PICU and hospital length of stay, abdominal distension, and nasal injury. RESULTS: A total of 11 615 citations were screened, and 9 randomized clinical trials with a total of 1421 participants were included. Both CPAP and HFNC were found to be more effective than COT in reducing EF and TF (CPAP: OR for EF, 0.43; 95% CrI, 0.17-1.0 and OR for TF 0.27, 95% CrI 0.11-0.57 and HFNC: OR for EF, 0.64; 95% CrI, 0.24-1.0 and OR for TF, 0.34; 95% CrI, 0.16- 0.65). CPAP had the highest likelihood of being the best intervention for both EF (SUCRA, 0.83) and TF (SUCRA, 0.91). Although not statistically significant, BiPAP was likely to be better than COT for preventing both EF and TF. Compared to COT, CPAP and BiPAP were reported as showing a modest increase (approximately 3%) in nasal injury and abdominal distension. CONCLUSIONS AND RELEVANCE: The studies included in this systematic review and network meta-analysis found that compared with COT, EF and TF rates were lower with modest increases in abdominal distension and nasal injury. Of the modes evaluated, CPAP was associated with the lowest rates of EF and TF.Item Executive Summary: International Clinical Practice Guidelines for Pediatric Ventilator Liberation, A PALISI Network Document(American Thoracic Society Journals, 2022-08-15) Abu-Sultaneh, Samer; Iyer, Narayan Prabhu; Fernández, Analía; Gaies, Michael; González-Dambrauskas, Sebastián; Hotz, Justin Christian; Kneyber, Martin C.J.; López-Fernández, Yolanda M.; Rotta, Alexandre T.; Werho, David K.; Baranwal, Arun Kumar; Blackwood, Bronagh; Craven, Hannah J.; Curley, Martha A.Q.; Essouri, Sandrine; Fioretto, Jose Roberto; Hartmann, Silvia M.M.; Jouvet, Philippe; Korang, Steven Kwasi; Rafferty, Gerrard F.; Ramnarayan, Padmanabhan; Rose, Louise; Tume, Lyvonne N.; Whipple, Elizabeth C.; Wong, Judith Ju Ming; Emeriaud, Guillaume; Mastropietro, Christopher W; Napolitano, Natalie; Newth, Christopher J.L.; Khemani, Robinder G.RATIONALE: Pediatric specific ventilator liberation guidelines are lacking despite the many studies exploring elements of extubation readiness testing. The lack of clinical practice guidelines has led to significant and unnecessary variation in methods used to assess pediatric patients' readiness for extubation. METHODS: Twenty-six international experts comprised a multi-professional panel to establish pediatric specific ventilator liberation clinical practice guidelines, focusing on acutely hospitalized children receiving invasive mechanical ventilation for more than 24 hours. Eleven key questions were identified and first prioritized using the Modified Convergence of Opinion on Recommendations and Evidence. Systematic review was conducted for questions which did not meet an a-priori threshold of ≥80% agreement, with Grading of Recommendations, Assessment, Development, and Evaluation methodologies applied to develop the guidelines. The panel evaluated the evidence, drafted, and voted on the recommendations. MEASUREMENTS AND MAIN RESULTS: Three questions related to systematic screening, using an extubation readiness testing bundle and use of a spontaneous breathing trial as part of the bundle met Modified Convergence of Opinion on Recommendations criteria of ≥80% agreement. For the remaining 8 questions, 5 systematic reviews yielded 12 recommendations related to the methods and duration of spontaneous breathing trials; measures of respiratory muscle strength; assessment of risk of post-extubation upper airway obstruction and its prevention; use of post-extubation non-invasive respiratory support; and sedation. Most recommendations were conditional and based on low to very low certainty of evidence. CONCLUSION: This clinical practice guideline provides a conceptual framework with evidence-based recommendations for best practices related to pediatric ventilator liberation.Item A Network Meta-analysis of Dexamethasone for Preventing Post-Extubation Upper Airway Obstruction in Children(American Thoracic Society Journals, 2022-08-17) Iyer, Narayan Prabhu; López-Fernández, Yolanda M.; González-Dambrauskas, Sebastián; Baranwal, Arun K.; Hotz, Justin C.; Zhu, Meng; Zhang, Yuan; Craven, Hannah J.; Whipple, Elizabeth C.; Abu-Sultaneh, Samer; Khemani, Robinder G.RATIONALE: Peri-extubation corticosteroids are commonly used in children to prevent upper airway obstruction (UAO). However, the best timing and dose combination of corticosteroids is unknown. OBJECTIVES: To compare effectiveness of different corticosteroid regimens in preventing UAO and reintubation. METHODS: MEDLINE, CINAHL and Embase search identified randomized trials in children using corticosteroids to prevent UAO. All studies used dexamethasone. The studies were categorized based on timing of initiation of dexamethasone (early use: >12 hours prior to extubation) and the dose (high dose: (>/= 0.5mg/kg/dose). We performed Bayesian network meta-analysis (NMA) with studies grouped into four regimens- High dose, Early use (HE); Low dose, Early use (LE); High dose, Late use (HL) and Low dose, Late use (LL). RESULTS: 8 trials (n=903) were included in the analysis. For preventing UAO, (odds ratio, 95% credible interval), HE (0.13; 0.04, 0.36), HL (0.39; 0.19, 0.74) and LE (0.15; 0.04, 0.58) regimens appear to be more effective compared to no dexamethasone (low certainty). HE and LE had the highest probability of being the top ranked regimens for preventing UAO [surface under the cumulative ranking (SUCRA) 0.901 and 0.808 respectively]. For preventing reintubation, the effect estimate was imprecise for all four dexamethasone regimens compared to no dexamethasone (very low certainty). HE and LE were the top ranked regimens (SUCRA 0.803 and 0.720 respectively) for preventing reintubation. Sensitivity analysis showed that regimens which started >12 hours prior to extubation were likely more effective than regimens started >6 hours prior to extubation. CONCLUSIONS: Peri-extubation dexamethasone can prevent post-extubation UAO in children but effectiveness is highly dependent on timing and dosing regimen. Early initiation (ideally >12 hours prior to extubation) appears to be more important than the dose of dexamethasone. Ultimately the specific steroid strategy should be personalized considering the potential for adverse events associated with dexamethasone and the individual risk of UAO and reintubation.Item Operational Definitions related to Pediatric Ventilator Liberation(Elsevier, 2022-12-20) Abu-Sultaneh, Samer; Iyer, Narayan Prabhu; Fernández, Analía; Gaies, Michael; González-Dambrauskas, Sebastián; Hotz, Justin Christian; Kneyber, Martin C.J.; López-Fernández, Yolanda M.; Rotta, Alexandre T.; Werho, David K.; Baranwal, Arun Kumar; Blackwood, Bronagh; Craven, Hannah J.; Curley, Martha A.Q.; Essouri, Sandrine; Fioretto, Jose Roberto; Hartmann, Silvia M.M.; Jouvet, Philippe; Korang, Steven Kwasi; Rafferty, Gerrard F.; Ramnarayan, Padmanabhan; Rose, Louise; Tume, Lyvonne N.; Whipple, Elizabeth C.; Wong, Judith Ju Ming; Emeriaud, Guillaume; Mastropietro, Christopher W.; Napolitano, Natalie; Newth, Christopher J.L.; Khemani, Robinder G.BACKGROUND: Common, operational definitions are crucial to assess interventions and outcomes related to pediatric mechanical ventilation. These definitions can reduce unnecessary variability amongst research and quality improvement efforts, to ensure findings are generalizable and can be pooled to establish best practices. RESEARCH QUESTION: Can we establish operational definitions for key elements related to pediatric ventilator liberation using a combination of detailed literature review and consensus-based approaches? STUDY DESIGN AND METHODS: A panel of 26 international experts in pediatric ventilator liberation, two methodologists and two librarians conducted systematic reviews on eight topic areas related to pediatric ventilator liberation. Through a series of virtual meetings, we established draft definitions which were voted upon using an anonymous web-based process. Definitions were revised by incorporating extracted data gathered during the systematic review and discussed in another consensus meeting. A second round of voting was conducted to confirm the final definitions. RESULTS: In eight topic areas identified by the experts, 16 preliminary definitions were established. Based on initial discussion and the first round of voting, modifications were suggested for 11 of the 16 definitions. There was significant variability in how these items were defined in the literature reviewed. The final round of voting achieved ≥80% agreement for all 16 definitions in the following areas: what constitutes respiratory support (invasive mechanical ventilation and non-invasive respiratory support), liberation and failed attempts to liberate from invasive mechanical ventilation, liberation from respiratory support, duration of non-invasive respiratory support, total duration of invasive mechanical ventilation, spontaneous breathing trials, extubation readiness testing, 28-ventilator free days, and planned vs rescue use of post-extubation non-invasive respiratory support. INTERPRETATION: We propose these consensus-based definitions for elements of pediatric ventilator liberation, informed by evidence, be used for future quality improvement initiatives and research studies to improve generalizability, and facilitate comparison.
