[PMID: 38197495 DOI: 10.1002/ppul.26860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 12/04/2023] [Accepted: 01/02/2024] [Indexed: 01/11/2024]
Abstract
INTRODUCTION High-flow nasal cannula (HFNC) is commonly used as first step respiratory support in infants with moderate-to-severe acute viral bronchiolitis (AVB). This device, however, fails to effectively manage respiratory distress in about a third of patients, and data are limited on determinants of patient response. The respiratory rate-oxygenation (ROX) index is a relevant tool to predict the risk for HFNC failure in adult patients with lower respiratory tract infections. The primary objective of this study was to assess the relationship between ROX indexes collected before and 1 h after HFNC initiation, and HFNC failure occurring in the following 48 h in infants with AVB. METHOD This is an ancillary study to the multicenter randomized controlled trial TRAMONTANE 2, that included 286 infants of less than 6 months with moderate-to-severe AVB. Collection of physiological variables at baseline (H0), and 1 h after HFNC (H1), included heart rate (HR), respiratory rate (RR), fraction of inspired oxygen (FiO2 ), respiratory distress score (modified Wood's Clinical Asthma Score [mWCAS]), and pain and discomfort scale (EDIN). ROX and ROX-HR were calculated asSpO 2 FiO 2 RR $\frac{\left(\frac{{\mathrm{SpO}}_{2}}{{\mathrm{FiO}}_{2}}\right)}{\mathrm{RR}}$ and100 × ROX HR $100\times \frac{\mathrm{ROX}}{\mathrm{HR}}$ , respectively. Predefined HFNC failure criteria included increase in respiratory distress score or RR, increase in discomfort, and severe apnea episodes. The accuracies of ROX, ROX-HR indexes and clinical variable to predict HFNC failure were assessed using receiver operating curve analysis. We analyzed predictive factors of HFNC failure using multivariate logistic regressions. RESULT HFNC failure occurred in 111 of 286 (39%) infants, and for 56 (50% of the failure) of them within the first 6 h. The area under the curve of ROX indexes at H0 and H1 were, respectively, 0.56 (95% confidence interval [CI] 0.48-0.63, p = 0.14), 0.56 (95% CI 0.49-0.64, p = 0.09). ROX-HR performances were better but remained poorly discriminant. HFNC failure was associated with higher mWCAS score at H1 (p < 0.01) and lower decrease in EDIN scale during the first hour of HFNC delivery (p = 0.02). In the multivariate analyses, age and mWCAS score were were found to be independent factors associated with HFNC failure at H0. At H1, weight and mWCAS were associated factors. CONCLUSION In this study, neither ROX index, nor physiological variables usually collected in infants with AVB had early discriminatory capacity to predict HFNC failure.

Abstract
Bronchiolitis is a common seasonal viral illness in babies and children aged under two years. Its significance has increased in the light of a predicted surge in respiratory illness in children this winter and the continuing effect of the coronavirus disease 2019 (COVID-19) pandemic on parental anxiety and cross-infection. Children's nurses will have a central role in delivering high-quality care and support to children and families during this time. To support children's nurses to prepare for a surge, this article summarises the pathophysiology of bronchiolitis, risk factors, transmission, diagnosis and clinical management of children with the illness, including recent national policy changes. It also considers the potential effect of the COVID-19 pandemic on the healthcare system, children and families.

Eur J Pediatr 2022; 181:3977-3983. [PMID: 36102995 PMCID: PMC9525568 DOI: 10.1007/s00431-022-04607-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Revised: 08/27/2022] [Accepted: 09/01/2022] [Indexed: 11/15/2022]
Abstract
UNLABELLED Our objective was to evaluate the association of respiratory rate oxygenation index (ROX) with the need for positive pressure ventilation in children < 2 years of age with bronchiolitis on high flow nasal cannula (HFNC) therapy. We performed a single-center prospective observational study of a convenience sample of children < 2 years of age with bronchiolitis who had HFNC initiated in the pediatric emergency department between November and March, 2018-2020. ROX was calculated as pulse oximetry/FiO2/respiratory rate at HFNC initiation. Demographics, need for positive pressure ventilation (PPV), disposition, and hospital length of stay were collected. Logistic regression model was used to determine the odds ratio for PPV need relative to the highest ROX quartile. Of the 373 patients included, 49 (13.1%) required PPV. ROX was lower in patients who required PPV compared with those who did not (5.86 [4.71-7.42] vs. 6.74 [5.46-8.25]; p = 0.01). Logistic regression revealed that those patients whose ROX was in the lowest quartile (< 5.39) were three times more likely to require PPV compared to those in the highest quartile (> 8.21). These results held true after adjusting for confounders (odds ratio 3.1; 95% CI [1.3 to 7.5]; p = 0.02). The model's AUROC (0.701) indicated acceptable discrimination between cases and controls. CONCLUSION Low ROX index was associated with the need for PPV in children with bronchiolitis on HFNC. The risk stratification provided and ROX threshold for risk stratification require confirmation in other populations with a larger sample size. WHAT IS KNOWN • Demographic and clinical factors associated with high flow nasal cannula (HFNC) therapy in children with bronchiolitis has been studied. WHAT IS NEW • This is the first study to report the utility of association of Respiratory Rate Oxygenation (ROX) index for need for positive pressure ventilation (PPV) in children < 2 years of age with bronchiolitis on HFNC therapy. • ROX was lower in children who required PPV and children whose ROX was in the lowest quartile (< 5.39) were three times more likely to require PPV compared to those in the highest quartile (> 8.21).

Abstract
BACKGROUND The aim of this study was to determine the predictive risk factors for development of severe bronchiolitis in patients with acute bronchiolitis with no previous chronic disease. METHODS Four hundred forty children aged 1-24 months hospitalised with acute bronchiolitis, were examined between February 2018 and February 2019 in this prospective study. RESULTS Eighty-five cases were regarded as severe bronchiolitis and 355 as mild-moderate bronchiolitis. Statistically significant differences were observed between the severe and mild-moderate bronchiolitis groups in terms of weight-for-age z-scores, history of bronchiolitis, haemoglobin levels, and time elapsed between the onset of symptoms and admission. Weight-for-age z-scores, the mean time interval between the onset of symptoms and admission, and mean haemoglobin values were lower in the severe bronchiolitis group while the mean number of bronchiolitis attacks was higher than in the mild-moderate bronchiolitis group. Logistic regression analysis determined that a low weight-for-age z-score increased the risk of severe bronchiolitis development 0.56-fold (CI: 0.409-0.760), a short duration between the onset of symptoms and admission increased the risk 0.62-fold (CI: 0.519-0.735), a frequent history of bronchiolitis increased the risk 1.81-fold (CI: 1.135-2.968) and low haemoglobin levels increased the risk 0.72-fold (CI: 0.537-0.969). CONCLUSION Low weight-for-age z-scores, a short duration between the onset of symptoms and admission, a high number of previous attacks and low haemoglobin levels were identified as independent parameters of severe bronchiolitis development.

Abstract
BACKGROUND Nasal continuous positive airway pressure (nCPAP) has been increasingly applied in the pediatric setting. However, there is no uniform standard for setting and titrating positive end-expiratory pressure (PEEP) level, which is paramount to the effectiveness of the treatment. This study aimed to investigate the optimal parameters for nCPAP in the treatment of severe bronchiolitis based on clinical efficacy and pulmonary function parameters. METHODS A before-after prospective study was conducted with a total of 152 study subjects. These 152 hospitalized patients with severe bronchiolitis were treated and observed from December 2018 to February 2019. Comparisons were made between subjects for clinical symptoms, oxygenation improvement, correction of CO2 retention, degree of airway obstruction and respiratory mechanics improvement between three different positive end-expiratory pressure levels (PEEP). RESULTS nCPAP could effectively improve the clinical manifestations, blood gas analysis, pulmonary function and respiratory muscle energy consumption. The m-WCAS score, PaCO2, TPTEF/TE, VPEF/VE, respiratory system compliance (Crs) and resistance (Rrs) were significantly different at different PEEP levels (P<0.05). Although there were no hemodynamic changes at peep parameter levels in the three groups. Group 2 (PEEP: 6 cmH2O) had optimal clinical effects, and improvement in airway obstruction and respiratory mechanics compared with the group 1 (PEEP: 4 cmH2O) and the group 3 (PEEP: 7 cmH2O). CONCLUSIONS PEEP of 6 cmH2O via nCPAP is considered as the optimal level in the treatment of infants with severe bronchiolitis.

Abstract
OBJECTIVES To explore the predictive ability of capillary blood gas (CBG) pCO2 for respiratory decompensation in infants aged ≤6 months with bronchiolitis admitted from the emergency department; to determine whether end-tidal CO2 (etCO2) capnography can serve as a less invasive substitute for CBG pCO2. STUDY DESIGN This was a prospective cohort study of previously healthy infants aged ≤6 months admitted for bronchiolitis from the emergency department (ED). Initial CBG pCO2 and etCO2 capnography were obtained in the ED prior to inpatient admission. Simple logistic regression modeling was used to examine the associations of CBG pCO2 and etCO2 capnography with respiratory decompensation. Pearson's correlation measured the relationship between CBG pCO2 and etCO2 capnography. RESULTS Of 134 patients, 61 had respiratory decompensation. There was a significant association between CBG pCO2 and respiratory decompensation (OR = 1.07, p = 0.003), even after outlying values were excluded (OR = 1.06, p = 0.005). End tidal CO2 capnography was not significantly associated with decompensation (OR = 1.02, p = 0.17), even after outlying values were excluded (OR = 1.02, p = 0.24). There was a moderate correlation between etCO2 capnography and CBG pCO2 (r = 0.39, p < 0.001). CONCLUSION In infants with bronchiolitis, CBG pCO2 provides an objective measure for predicting respiratory decompensation, and a single etCO2 measurement should not replace its use.

Abstract
OBJECTIVES The appropriateness of interfacility transfer admissions for bronchiolitis to pediatric centers is uncertain. We characterized avoidable transfer admissions for bronchiolitis. We hypothesized that a higher proportion of hospitalized infants transferred from a community emergency department (ED) or hospital (transfer admission) would be discharged within 48 hours with little or no intervention, compared with direct admissions from an enrolling ED (nontransfer admission). METHODS We analyzed a 17-center, prospective infant cohort (age <1 year) hospitalized for bronchiolitis (2011-2014). An avoidable transfer admission (primary outcome) was hospitalization for <48 hours without an intervention for severe illness in which a pediatric specialist could be beneficial (oxygen, advanced airway management, life support). Parenteral fluids and routine medications were excluded. We compared admissions by patient, ED, inpatient, and transferring hospital characteristics to identify factors associated with avoidable transfer admissions. Multivariable logistic regression was used to identify predictors of avoidable transfer admission. RESULTS Among 1007 infants, 558 (55%) were nontransfer admissions, 164 (16%) were transfer admissions, and 204 (20%) were referrals from clinics; 81 (8%) were missing referral type. Significantly fewer transferred infants were hospitalized for <48 hours with little or no intervention (40 of 164; 24% [95% confidence interval 18%-32%]) than nontransferred infants (199 of 558; 36% [95% confidence interval 32%-40%]; P = .007). Avoidable transfer admissions were more likely to be children of color, have nonprivate insurance, receive fewer ED interventions, and originate from small EDs. A multivariable model revealed that minority race and/or ethnicity, normal oxygenation, and small ED transfers increased odds of avoidable transfer admission. CONCLUSIONS Although most transferred infants hospitalized for bronchiolitis required interventions for severe illness, 1 in 4 admissions were potentially avoidable.

Abstract
Viral testing is not always recommended in children with bronchiolitis due to doubts concerning its prognostic use. In this retrospective study, we investigated how the RSV testing would influence the frequency of nosocomial infections (NI). The files of 305 children, hospitalized due to the respiratory syncytial virus (RSV) infection in the period 2010-2014, were reviewed in the study. We found ten cases of NI. The RSV preventive measures did not vary in the consecutive years investigated, but the number of viral tests substantially varied. In 2010, 2012, and 2014, when ca. 2 tests per RSV(+) patient were performed, the risk of NI per patient was 1.3%, while in 2011 and 2013, when the RSV testing was less frequent, the accumulated risk per patient was 5.2%. There was a strong adverse relationship between the number of tests performed and the number of NI (rho = -0.975). The children with NI, when compared to those without NI, required a longer hospital stay, generating higher hospital costs regarding treatment, productivity loss, and indirect costs. The expenditure for RSV testing in the years of a low NI risk was higher than that in the high-risk years. Conversely, the expenditure related to NI management was lower in the years of a low NI risk. Each euro spent on RSV testing saved over 26 € from the NI management expenditure. We conclude that RSV testing is needed in the hospital setting to isolate the infected children and to prevent nosocomial RSV spread. This strategy is health advantageous and requires less resources than NI treatment.

Abstract
OBJECTIVE We aimed to compare the heated humidified high-flow nasal cannula (HHHFNC) flow rate of 1-L·kg·min-1 (1 L) with 2-L·kg·min -1 (2 L) in patients with severe bronchiolitis presenting to the pediatric emergency department. STUDY DESIGN We performed a study in which all patients were allocated to receive these two flow rates. The primary outcome was admitted as treatment failure, which was defined as a clinical escalation in respiratory status. Secondary outcomes covered a decrease of respiratory rate (RR), heart rate (HR), the clinical respiratory score (CRS), rise of peripheral capillary oxygen saturation (SpO2 ), and rates of weaning, intubation, and intensive care unit (ICU) admission. RESULTS One hundred and sixty-eight cases (88 received the 1-L flow rate and 80, the 2-L flow rate) were included in the analyses. Treatment failure was 11.4% (10 of 88) in the 1-L group, and 10% (8 of 80) in the 2-L group (P = .775). Significant variation in the intubation rate or the ICU admission rate was not determined. At the 2nd hour, the rate of weaning (53.4% vs 35%; P = .017), the falling down of the CRS (-2.1 vs -1.5; P < .001), RR (-15.2 vs -11.8; P < .001), and HR (- 24.8 vs - 21.2; P < .001), and the increase of SpO 2 (4.8 vs 3.6; P < .001) were significantly more evident in the 1-L group. CONCLUSION HHHFNC with the 1-L·kg·min-1 flow rate, which provides a more frequent earlier effect, reached therapy success as high as the 2-L·kg·min -1 flow rate in patients with severe acute bronchiolitis.

Abstract
OBJECTIVE To use a large current prospective cohort of infants <29 weeks to compare bronchopulmonary dysplasia (BPD) rates in black and white infants. STUDY DESIGN The Prematurity and Respiratory Outcome Program (PROP) enrolled 835 infants born in 2011-2013 at <29 weeks of gestation; 728 black or white infants survived to 36 weeks postmenstrual age (PMA). Logistic regression was used to compare BPD outcomes (defined as supplemental oxygen requirement at 36 weeks PMA) between the races, adjusted for gestational age (GA), antenatal steroid use, intubation at birth, and surfactant use at birth. RESULTS Of 707 black or white infants with available BPD outcomes, BPD was lower in black infants (38% vs 45%), even though they were of significantly lower GA. At every GA, BPD was more common in white infants. The aOR for BPD was 0.60 (95% CI, 0.42-0.85; P = .004) for black infants compared with white infants after adjusting for GA. Despite the lower rate of BPD, black infants had a higher rate of first-year post-prematurity respiratory disease (black, 79%; white, 63%). CONCLUSIONS In this large cohort of recently born preterm infants at <29 weeks GA, compared with white infants, black infants had a lower risk of BPD but an increased risk of persistent respiratory morbidity.

Abstract
INTRODUCTION We performed a retrospective study to evaluate demographics, clinical course, outcome, and radiological findings of children with respiratory syncytial virus (RSV) infection. METHODS Four hundred patients admitted between October 2013 and May 2016 were enrolled. Clinical and radiographic trends were evaluated for association with severity of RSV presentation. Severity was defined as hospitalization >2 days, pediatric intensive care unit admission, or need for mechanical ventilation. RESULTS Common clinical findings included fever (78.5%), coughing (97%), rhinorrhea/congestion (93%), and hypoxia (44.8%). Hypoxia was seen in 64.7% of the severe group compared with 32.0% in the nonsevere group ( P < .001). Airspace opacification was seen in 49.2% of chest X-rays of the severe group compared with 26.4% in the nonsevere group ( P < .001). CONCLUSION Higher incidence of hypoxia or airspace opacification on chest X-ray may be predictors of poorer outcomes for patients with RSV infection.

Abstract
BACKGROUND AND OBJECTIVES Early risk stratification of infants with bronchiolitis receiving airway support is critical for focusing appropriate therapies, yet the tools to risk categorize this subpopulation do not exist. Our objective was to identify predictors of "escalated care" in bronchiolitis. We hypothesized there would be a significant association between escalated care and predictors in the emergency department. We subsequently developed a risk score for escalated care. METHODS We conducted a retrospective cohort study of previously healthy infants aged <12 months with bronchiolitis. Our primary outcome was escalated care (ie, hospitalization with high-flow nasal cannula, noninvasive or invasive ventilation, or intensive care admission). The predictors evaluated were age, prematurity, day of illness, poor feeding, dehydration, apnea, nasal flaring and/or grunting, respiratory rate, oxygen saturation, and retractions. RESULTS Of 2722 patients, 261 (9.6%) received escalated care. Multivariable predictors of escalated care were oxygen saturation <90% (odds ratio [OR]: 8.9 [95% confidence interval (CI) 5.1-15.7]), nasal flaring and/or grunting (OR: 3.8 [95% CI 2.6-5.4]), apnea (OR: 3.0 [95% CI 1.9-4.8]), retractions (OR: 3.0 [95% CI 1.6-5.7]), age ≤2 months (OR: 2.1 [95% CI 1.5-3.0]), dehydration (OR 2.1 [95% CI 1.4-3.3]), and poor feeding (OR: 1.9 [95% CI 1.3-2.7]). One of 217 (0.5%) infants without predictors received escalated care. The risk score ranged from 0 to 14 points, with the estimated risk of escalated care from 0.46% (0 points) to 96.9% (14 points). The area under the curve was 85%. CONCLUSIONS We identified variables measured in the emergency department predictive of escalated care in bronchiolitis and derived a risk score to stratify risk of this outcome. This score may be used to aid management and disposition decisions.
