Lung-Protective Ventilation for Pediatric Acute Respiratory Distress Syndrome: A Nonrandomized Controlled Trial.

OBJECTIVES: Despite the recommendation for lung-protective mechanical ventilation (LPMV) in pediatric acute respiratory distress syndrome (PARDS), there is a lack of robust supporting data and variable adherence in clinical practice. This study evaluates the impact of an LPMV protocol vs. standard care and adherence to LPMV elements on mortality. We hypothesized that LPMV strategies deployed as a pragmatic protocol reduces mortality in PARDS. DESIGN: Multicenter prospective before-and-after comparison design study. SETTING: Twenty-one PICUs. PATIENTS: Patients fulfilled the Pediatric Acute Lung Injury Consensus Conference 2015 definition of PARDS and were on invasive mechanical ventilation. INTERVENTIONS: The LPMV protocol included a limit on peak inspiratory pressure (PIP), delta/driving pressure (DP), tidal volume, positive end-expiratory pressure (PEEP) to Fio2 combinations of the low PEEP acute respiratory distress syndrome network table, permissive hypercarbia, and conservative oxygen targets. MEASUREMENTS AND MAIN RESULTS: There were 285 of 693 (41·1%) and 408 of 693 (58·9%) patients treated with and without the LPMV protocol, respectively. Median age and oxygenation index was 1.5 years (0.4-5.3 yr) and 10.9 years (7.0-18.6 yr), respectively. There was no difference in 60-day mortality between LPMV and non-LPMV protocol groups (65/285 [22.8%] vs. 115/406 [28.3%]; p = 0.104). However, total adherence score did improve in the LPMV compared to non-LPMV group (57.1 [40.0-66.7] vs. 47.6 [31.0-58.3]; p < 0·001). After adjusting for confounders, adherence to LPMV strategies (adjusted hazard ratio, 0.98; 95% CI, 0.97-0.99; p = 0.004) but not the LPMV protocol itself was associated with a reduced risk of 60-day mortality. Adherence to PIP, DP, and PEEP/Fio2 combinations were associated with reduced mortality. CONCLUSIONS: Adherence to LPMV elements over the first week of PARDS was associated with reduced mortality. Future work is needed to improve implementation of LPMV in order to improve adherence.

Scedosporium Infection in Recipients of Kidney Transplants from Deceased Near-Drowning Donor.

Scedosporium aurianticum infection developed in 2 recipients of kidney transplants in India, acquired from the same deceased near-drowning donor. Given the substantial risk for death associated with Scedosporium infection among solid-organ transplant recipients, safety protocols for organ transplantation from nearly drowned donors should be thoroughly revaluated and refined.

An Observational Study on Pattern of Empirical Acyclovir Therapy in Children With Acute Encephalitis From Northern India.

OBJECTIVES: To identify the prevalence of herpes simplex encephalitis (HSE), factors influencing the duration of empirical acyclovir and frequency of acute kidney injury (AKI) in children with acute encephalitis syndrome (AES). DESIGN: Prospective observational study. SETTING: Pediatric Emergency Department and PICU of a tertiary hospital in Northern India. PATIENTS: All consecutive, eligible children between 1 month and 12 years old presenting with AES, defined as altered consciousness for greater than 24 hours (including lethargy, irritability, or a change in personality) and two or more of the following signs: 1) fever (temperature ≥ 38°C) during the current illness, 2) seizures or focal neurological signs, 3) cerebrospinal fluid (CSF) pleocytosis, 4) electroencephalogram, and/or 5) neuroimaging suggesting encephalitis, who received at least one dose of acyclovir. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 101 children screened, 83 were enrolled. The median (interquartile range [IQR]) age was 3 years (1-6 yr). Thirty-one children (37.3%) were diagnosed with AES, of which four were labeled as probable HSE (three based on MRI brain, one based on serology). Scrub typhus, dengue, Japanese encephalitis, and mumps were the other infective causes. The median (IQR) duration of acyclovir therapy was 72 hours (24-264 hr); 21 children (25.3%) received acyclovir for less than 24 hours and 11 (13.3%) for greater than or equal to 14 days. New-onset AKI was seen in 18 children (21.7%) but was mostly transient. Death ( n = 8, 9.6%) and discontinuation of care due to futility or other reasons ( n = 15, 18%) were noted in 23 children (28%). Factors associated with duration of acyclovir greater than 7 days, on univariable analysis, were lower modified Glasgow Coma Score at admission, requirement of invasive ventilation, invasive intracranial pressure monitoring, and CSF pleocytosis (5-500 cells). On multivariable analysis, only CSF pleocytosis of 5-500 cells was associated with duration of acyclovir greater than 7 days. CONCLUSIONS: Given the low prevalence of HSE, and the risk of AKI, this study sensitizes the need to review our practice on initiation and stopping of empirical acyclovir in children with acute encephalitis.

Psychosocial issues among paediatric health-care workers posted in intensive care unit during COVID-19 pandemic: A questionnaire-based survey (Psy-Co-19 survey).

AIM: To understand the moral distress experienced by health-care workers (HCWs) in the COVID paediatric intensive care unit (PICU). We also aimed to assess the psychological well-being and the coping mechanisms used by HCWs. METHODS: A prospective observational cross-sectional study was conducted from July to September 2021, involving all HCWs who worked in the COVID PICU. Moral distress using Moral Distress for Health-care Professionals (MMD-HPs) scale, psychological well-being using Trauma Screening Questionnaire (TSQ) and coping strategies adopted by HCWs using Brief-COPE (Coping Orientation to Problems Experienced) were measured. RESULTS: One hundred and eighty-four HCW data were examined. The most common causes of moral distress among HCWs were compromised patient care caused by a lack of resources and caring for more patients than they could safely handle. Moral distress was the same regardless of the HCWs' job profile, marital status, number of children or age. The TSQ revealed psychological stress in 23.3% of HCWs with Post-traumatic Stress Disorder, significantly higher in HCWs under the age of 30 and without children. Few HCWs turned to substance use, self-blame or denial as coping mechanisms; instead, acceptance, self-distraction and emotional support were the most frequently used. CONCLUSION: The most common reasons for moral and psychological distress perceived by participants were insufficient staff and organisational support. Younger HCWs and those without children experienced higher levels of psychological distress. HCWs' typical coping mechanisms are constructive, such as seeking help and support from others, reframing situations and meditation. Health-care administrators must develop a framework to assist HCWs in dealing with such serious issues.

Comparison of Blood Pressure Measurements by Currently Available Multiparameter Monitors and Mercury Column Sphygmomanometer in Patients Admitted in Pediatric Intensive Care Unit.

Background: The multiparameter monitor (MPM) is replacing mercury column sphygmomanometers (MCS) in acute care settings. However, data on the former's accuracy in critically ill children are scarce and mostly extrapolated from adults. We compared non-invasive blood pressure (NIBP) measurements by MPMs with MCS in pediatric intensive care unit (PICU). Patients: Adequately sedated and hemodynamically stabilized children (age, 1-144 months) were prospectively enrolled. Materials and methods: Three NIBP measurements were obtained from MCS (Diamond®, India) and MPM (Intellivue MX800® or Ultraview SL®) in rapid succession in the upper limb resting in supine position. Respective three measurements were averaged to obtain a paired set of NIBP readings, one each from MCS and MPM. Such readings were obtained thrice a day. NIBP readings were then compared, and agreement was assessed. Results: From 39 children [median age (IQR), 30 (10-72) months], 1,690 sets of NIBP readings were obtained. A-third of readings were from infants and children >96 months, while 383 (22.6%) readings were from patients on inotropes. Multiparameter monitors gave significantly higher NIBP readings compared to MCS [median systolic blood pressure (SBP), 6.5 (6.4-6.7 mm Hg); diastolic blood pressure (DBP), 4.5 (4.3-4.6 mm Hg); mean arterial pressure (MAP), 5.3 (5.1-5.4 mm Hg); p < 0.05]. It was consistent across age, gender, and critical care characteristics. Multiparameter monitors overestimated SBP in 80% of readings beyond the maximal clinically acceptable difference (MCAD). Conclusions: Non-invasive blood pressure readings from MCS and MPMs are not interchangeable; SBP was 6-7 mm Hg higher with the latter. Overestimation beyond MCAD was overwhelming. Caution is required while classifying systolic hypotension with MPMs. Confirmation with auscultatory methods is advisable. More studies are required to evaluate currently available MPMs in different pediatric age groups. How to cite this article: Khan AA, Gupta PK, Baranwal AK, Jayashree M, Sahoo T.

Clinical Profile, Intensive Care Needs and Outcome of Children with Dilated Cardiomyopathy Associated with Vitamin D Deficiency: A 5-year PICU Experience.

Aim: To describe the clinical profile, treatment details, intensive care needs, and long-term outcome of children with dilated cardiomyopathy (DCM) associated with Vitamin D deficiency (VDD). Materials and methods: Case records of 14 children with DCM associated with VDD [25(OH)D3 levels <20 ng/mL] admitted to the pediatric intensive care unit (PICU) of a tertiary care teaching hospital between January 2017 and December 2021 were retrospectively analyzed for clinical features, echocardiographic findings, treatment details, intensive care needs, and outcomes. Results: The median (IQR) age was 6 (2-9) months and 71% (n=10) were males. The common modes of presentation included respiratory distress or failure (78.6%), congestive cardiac failure (71.4%), cardiogenic shock (37.5%), and seizures and encephalopathy (14.3% each). The median (IQR) serum calcium was 8.7 (7-9.5) mg%, ionized calcium 0.7 (0.7-1.1) mmol/L, alkaline phosphatase 343 (316-415) IU/L, phosphate 3.5 (2.6-4.5) mg%, PTH 115 (66-228) pg/mL, and 25(OH)D3 5 (3-7) ng/mL. The median (IQR) left ventricular ejection fraction (LVEF) at admission was 22 (17-25)%. The treatment included intravenous calcium infusion (35.7%), vitamin D supplementation in all (57.1% parenteral and 42.9% oral), mechanical ventilation (35.7%), and vasoactive drugs (57.1%). There was no mortality. The median (IQR) duration of PICU and hospital stay was 76 (31-98) hours and 6 (4.7-10) days, respectively. Out of 14 children, 10 (71.4%) were followed-up till median (IQR) of 10 (7-58) months. All were asymptomatic and had normal LEVF (except one had residual moderate mitral regurgitation). Conclusion: Vitamin D deficiency is a potentially treatable and reversible cause of DCM in children.

Clinical Features Associated With Need for Mechanical Ventilation in Children With Guillain-Barré Syndrome: Retrospective Cohort From India.

OBJECTIVES: To analyze the clinical features associated with the need for mechanical ventilation (MV) in children with Guillain-Barré syndrome (GBS). DESIGN: Retrospective cohort study, 2010-2019. SETTING: PICU. PATIENTS: All children, 1 month to 12 years old, diagnosed with GBS in our single-center PICU. INTERVENTION: Retrospective chart and data review. MEASUREMENTS AND MAIN RESULTS: Out of 189 children identified with a diagnosis of GBS, 130 were boys (69%). The median (interquartile range [IQR]) age was 6 years (3-9 yr). At admission, the Hughes disability score was 5 (4-5), and cranial nerve palsies were present in 81 children (42%). Autonomic instability subsequently occurred in a total of 97 children (51%). In the 159 children with nerve conduction studies, the axonal variant of GBS (102/159; 64%) predominated, followed by the demyelinating variant (38/189; 24%). All children received IV immunoglobulins as first-line therapy at the time of admission. The median (IQR) length of PICU stay was 12 days (3-30.5 d). Ninety-nine children (52%) underwent invasive MV, and median duration of MV was 25 days (19-37 d). At admission, upper limb power less than or equal to 3 (p = 0.037; odds ratio (OR), 3.5 [1.1-11.5]), lower limb power less than or equal to 2 (p = 0.008; OR, 3.5 [1.4-8.9]), and cranial nerve palsy (p = 0.001; OR, 3.2 [1.6-6.1]) were associated with subsequent need for MV. Prolonged (> 21 d) MV was associated with more severe examination findings at admission: upper limb power less than or equal to 2 (p < 0.0001; OR, 4.2 [2.5-6.9]) and lower limb power less than or equal to 1 (p < 0.0001; OR, 4.5 [2.6-7.9]). CONCLUSIONS: In children with GBS, referred to our center in North India, severe neuromuscular weakness at admission was associated with the need for MV. Furthermore, greater severity of this examination was associated with need for prolonged (> 21 d) MV. Identification of these signs may help in prioritizing critical care needs and early PICU transfer.

Mortality audit of COVID-19 infection among children.

Background & objectives: As severe COVID-19 and mortality are not common in children, there is a scarcity of data regarding the cause of mortality in children infected with SARS-CoV-2. This study was aimed to describe the all-cause mortality and COVID-19 death (disease-specific mortality) in children with SARS-CoV-2 infection admitted to a paediatric COVID facility in a tertiary care centre. Methods: Data with respect to clinical, epidemiological profile and causes of death in non-survivors (0-12 yr old) of SARS-CoV-2 infection admitted to a dedicated tertiary care COVID hospital in north India between April 2020 and June 2021 were retrieved and analyzed retrospectively. Results: A total of 475 SARS-CoV-2-positive children were admitted during the study period, of whom 47 died [18 neonates, 14 post-neonatal infants and 15 children (1-12 yr of age)]. The all-cause mortality and COVID-19 death (disease-specific mortality) were 9.9 per cent (47 of 475) and 1.9 per cent (9 of 475), respectively. Underlying comorbidities were present in 35 (74.5%) children, the most common being prematurity and perinatal complications (n=11, 24%) followed by congenital heart disease (n=6, 13%). The common causes of death included septic shock in 10 (21%), COVID pneumonia/severe acute respiratory distress syndrome in nine (19%), neonatal illnesses in eight (17%), primary central nervous system disease in seven (15%) and congenital heart disease with complication in six (13%) children. Interpretation & conclusions: Our results showed a high prevalence of underlying comorbidities and a low COVID-19 death (disease-specific mortality). Our findings highlight that mortality due to COVID-19 can be overestimated if COVID-19 death and all-cause mortality in children infected with SARS-CoV-2 are not separated. Standardized recording of cause of death in children with SARS-CoV-2 infection is important.

Is Lumbar Puncture Avoidable in Low-Risk Neonates with Suspected Sepsis?

OBJECTIVE: Performing lumbar punctures (LP) in all clinically suspected neonatal sepsis, as per current recommendations, results in many "negative" LPs. LPs are not without their own risks. With the intention of minimizing unnecessary LPs among neonates, we aimed to identify a subgroup at extremely low risk of developing possible meningitis so that an LP could be safely avoided in it. STUDY DESIGN: This was a prospective, observational, and cross-sectional study in a level III neonatal unit. We included 300 episodes, in which LP was performed for suspected sepsis. We recorded a comprehensive set of clinico-demographic variables, laboratory parameters, sickness score, organ dysfunction score, and organ localization and studied association of these factors with "definite (culture positive) or possible meningitis." "Possible" meningitis was defined with liberal criteria, intending not to miss any meningitis. A subgroup without a single factor associated with "definite or possible meningitis" was analyzed for incidence of meningitis. RESULTS: There were 121 episodes of "definite or possible meningitis" among 300 episodes of sepsis. On unadjusted analysis, apnea, irritability, high-pitched cry, seizures, neutrophilia, high C-reactive protein (CRP), score for acute neonatal physiology and perinatal extension II (SNAPPE-II), urine output, and leukomalacia were associated with "definite or possible" meningitis (p < 0.05). On multivariate analysis, no apneas, no neutrophilia, and normal CRP were independently associated with "no definite or possible meningitis." Nevertheless, the subgroup that had a combination of no apneas, no neutrophilia, and normal CRP (n = 118) had a 29% probability of "definite or possible meningitis." CONCLUSION: The lowest risk subgroup had a 29% chance of having "definite or possible" meningitis. There is no subgroup that we could identify among neonates with suspected sepsis, in which it is safe to avoid an LP. KEY POINTS: · LP are performed in all cases of late onset neonatal sepsis.. · Previous authors unsuccessfully tried to identify high-risk groups for performing LP.. · We were unable to identify an extremely low-risk group in which LP could be safely avoided..

Clinico-Laboratory Profile, Intensive Care Needs and Short-Term Outcome of Multisystem Inflammatory Syndrome in Children (MIS-C): Experience during First and Second Waves from North India.

OBJECTIVES: To describe the clinico-laboratory profile, intensive care needs and outcome of multisystem inflammatory syndrome in children (MIS-C) during the first and second waves. METHODOLOGY: This retrospective study was conducted in the paediatric emergency and paediatric intensive care unit (PICU) of a tertiary care teaching hospital in North India involving 122 children with MIS-C admitted during the first wave (September 2020-January 2021, n = 40) and second wave (February 2021-September 2021, n = 82) of coronavirus disease 2019 (COVID-19). RESULTS: The median (interquartile range) age was 7 (4-10) years and 67% were boys. Common manifestations included fever (99%), abdominal symptoms (81%), rash (66%) and conjunctival injection (65%). Elevated C-reactive protein (97%), D-dimer (89%), procalcitonin (80%), IL-6 (78%), ferritin (56%), N-terminal pro B-type natriuretic peptide (84%) and positive severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) antibody (81%) were common laboratory abnormalities. Cardiovascular manifestations included myocardial dysfunction (55%), shock (48%) and coronary artery changes (10%). The treatment included intensive care support (57%), non-invasive (33%) and invasive (18%) ventilation, vasoactive drugs (47%), intravenous immunoglobulin (IVIG) (83%), steroids (85%) and aspirin (87%). The mortality was 5% (n = 6). During the second wave, a significantly higher proportion had positive SARS-CoV-2 antibody, contact with COVID-19 and oral mucosal changes; lower markers of inflammation; lower proportion had lymphopenia, elevated IL-6 and ferritin; lower rates of shock, myocardial dysfunction and coronary artery changes; lesser need of PICU admission, fluid boluses, vasoactive drugs and IVIG; and shorter hospital stay. CONCLUSION: MIS-C is a febrile multisystemic disease characterized by hyperinflammation, cardiovascular involvement, temporal relationship to SARS-CoV-2 and good outcome with immunomodulation and intensive care. During the second wave, the severity of illness, degree of inflammation, intensive care needs, and requirement of immunomodulation were less as compared to the first wave.

Acute Diarrhea and Severe Dehydration in Children: Does Non-anion-gap Component of Severe Metabolic Acidemia Need More Attention?

Background: Despite significant loss of bicarbonate during acute diarrhea, pediatric data are scarce with acute diarrhea/severe dehydration (ADSD) and severe non-anion-gap metabolic acidemia (sNAGMA). We planned to study their clinical profile, critical care needs, and outcome. Patients: Children (1 month-12 years) with ADSD and sNAGMA (pH <7.2 and/or bicarbonate <15 mEq/L, and normal/mixed anion gap) admitted in Pediatric Emergency Department from January 2016 to December 2018 were enrolled. Children with pure high-anion-gap metabolic acidemia were excluded. Methods: Medical records were reviewed retrospectively. The primary outcome was time taken to resolve acidemia. Secondary outcomes were acute care area free days in 5 days (ACAFD5), and adverse outcome as composite of Pediatric Intensive Care Unit (PICU) admission and/or death. Results: Out of 929 diarrhea patients admitted for intravenous therapy, 121 (13%; median age, 4 months) had ADSD and sNAGMA. Median (IQR) pH was 7.11 (7.01-7.22); 21% patients had pH <7.00. Hyperchloremia (96%) and hypernatremia (45%) were common. About 12% patients each required inotropes and ventilation, while 58% had acute kidney injury (AKI). Median (IQR) time for resolution of acidemia among survivors was 24 (12, 24) hours. Thirty-two patients had adverse outcome. Higher grades of sNAGMA were associated with shock, AKI, coma, hypernatremia, hyperkalemia, adverse outcome, and lesser ACAFD5. Shock, ventilation, renal replacement therapy (RRT), and higher grades of sNAGMA were predictors of adverse outcome, with former two being independent predictors. Conclusion: Severe non-anion-gap metabolic acidemia in children with ADSD is associated with organ dysfunctions, dyselectrolytemias, and lesser ACAFD5. Resolution of acidemia took unacceptably longer time. Higher grades of sNAGMA were a predictor of adverse outcomes. Trials are suggested to assess the role of additional bicarbonate therapy.

Neuroimaging Spectrum of Severe Hypernatremia in Infants with Neurological Manifestations.

BACKGROUND: Variable neurological manifestations and imaging findings have been described in children with severe hypernatremia. We aimed to describe the spectrum of neuroimaging changes in infants with severe hypernatremia. METHODS: This retrospective study included infants with severe hypernatremia (serum sodium >160 mEq/L), abnormal neurological examination, and an abnormal magnetic resonance imaging (MRI) of the brain over a period of 2 years in a tertiary care hospital. Relevant clinical data, including the feeding practices, clinical features, complications, and biochemical and radiological parameters, were entered in a structured pro forma. MRI findings were classified as vascular (hemorrhages and cerebral sinus venous thrombosis), osmotic demyelination syndrome (pontine and extrapontine myelinolyses), and white matter changes. RESULTS: The common clinical features in the neonates were poor feeding (n = 4) and decreased urine output (n = 4); the older infants presented with gastrointestinal losses (n = 5). All cases had dehydration with encephalopathy. The patterns of radiological injury were vascular (hemorrhages, n = 5 and venous thrombosis, n = 3), osmotic demyelination (n = 8), and white matter changes (n = 7). Coagulopathy was correlated with the vascular complications (r = 0.8, p < 0.0001); the degree of dehydration was correlated with the venous thrombosis (r = 0.7, p < 0.04) and acute kidney injury (r = 0.8, p < 0.001). Neurological sequelae were seen in four cases and correlated with hypernatremia (r = 0.6, p = 0.03) and hyperosmolarity (r = 0.6, p = 0.03). CONCLUSION: Characteristic neuroimaging findings are vascular changes in the form of venous thrombosis and hemorrhages, osmotic demyelination and white matter tract injury, and/or mostly combinations of these findings. Severe hypernatremia and resulting hyperosmolarity frequently cause neurological sequelae in neonates and infants.

Hemophagocytic Lymphohistiocytosis in a PICU of a Developing Economy: Clinical Profile, Intensive Care Needs, Outcome, and Predictors of Mortality.

OBJECTIVES: To describe the clinical profile, intensive care needs, outcome, and predictors of mortality in critically ill children with hemophagocytic lymphohistiocytosis. DESIGN: Retrospective case series. SETTING: PICU of a tertiary care teaching hospital in North India. PATIENTS: Children 2 months to 12 years old with the diagnosis of hemophagocytic lymphohistiocytosis admitted to PICU from January 2012 to April 2019 (7» yr). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Sixty-two children with hemophagocytic lymphohistiocytosis (60 secondary and two primary) were enrolled. The median (interquartile range) age of the study group was 82 months (50.5-124 mo). The median (interquartile range) Pediatric Risk of Mortality III score was 16 (10-23). Majority of hemophagocytic lymphohistiocytosis was infection-associated (n = 51; 82.3%). Among these, scrub typhus accounted for 29% of cases (n = 18), dengue 17.7% (n = 11), bacterial sepsis 14.5% (n = 9), enteric fever 6.5% (n = 4), and other infections 14.5% (n = 9). Systemic-onset juvenile idiopathic arthritis accounted for 9.7% of cases (n = 6) and malignancy for 4.8% patients (n = 3). Majority of cases were treated with steroids (77.4%) and IV immunoglobulin (25.8%). Various complications noted were shock (71%), acute kidney injury (66.1%), acute respiratory distress syndrome (41.9%), disseminated intravascular coagulation (54.8%), CNS dysfunction (54.8%), multiple organ dysfunction syndrome (82.3%), and healthcare-associated infections (14.5%). Intensive care needs for primary illness and/or hemophagocytic lymphohistiocytosis included mechanical ventilation (74.2%); packed RBC (72.3%), fresh frozen plasma (40.3%), and platelet (48.4%) transfusion; vasoactive drugs (71%); and renal replacement therapy (24.2%). The median duration of PICU stay was 5 days (2.5-9.5 d) and mortality was 59.7% (n = 37). On univariate analysis, nonsurvivors had higher Pediatric Risk of Mortality III score; higher proportion of shock, acute kidney injury, acute respiratory distress syndrome, disseminated intravascular coagulation, and multiple organ dysfunction syndrome; the need for blood and blood components, mechanical ventilation, vasoactive drugs, and renal replacement therapy; higher Vasoactive-Inotropic Score; and prolonged duration of mechanical ventilation compared with survivors. CONCLUSIONS: Hemophagocytic lymphohistiocytosis in PICU is commonly secondary to tropical infections and associated with high mortality. Higher severity of illness; shock and multiple organ dysfunction syndrome; need for blood and blood products, mechanical ventilation, vasoactive drugs, and renal replacement therapy; higher Vasoactive-Inotropic Score; and prolonged mechanical ventilation predicted death. Treatment of underlying infection and a less intense immunosuppressive therapy (steroids ± IV immunoglobulin) are suggested options. A high index of suspicion for complicating hemophagocytic lymphohistiocytosis is required in children with prolonged fever, cytopenias, organomegaly, and organ dysfunction not responding to conventional treatment.

Prescription practice and clinical utility of chest radiographs in a pediatric intensive care unit: a prospective observational study.

BACKGROUND: Chest radiograph (CXR) prescribing pattern and practice vary widely among pediatric intensive care units (PICU). 'On demand' approach is increasingly recommended as against daily 'routine' CXRs; however, the real-world practice is largely unknown. METHODS: This was a prospective observational study performed in children younger than 12 years admitted to PICU of a tertiary care teaching hospital in India. Data were collected on all consecutive CXRs performed between December 2016 and April 2017. The primary outcome was to assess the factors that were associated with higher chest radiograph prescriptions in PICU. Secondary outcomes were to study the indications, association with mechanical ventilation, image quality and avoidable radiation exposure. RESULTS: Of 303 children admitted during the study period, 159 underwent a total of 524 CXRs in PICU. Median (IQR) age of the study cohort was 2 (0.6-5) years. More than two thirds [n = 115, 72.3%] were mechanically ventilated. Most CXRs (n = 449, 85.7%) were performed on mechanically ventilated patients, amounting to a median (IQR) of 3 (2-5) radiographs per ventilated patient. With increasing duration of ventilation, the number of CXRs proportionately increased in the first two weeks of mechanical ventilation. In non-ventilated children, about two thirds (68%) underwent only one CXR. Majority of the prescriptions were on demand (n = 461, 88%). Most common indications were peri-procedure prescriptions (37%) followed by evaluation for respiratory disease status (24%). About 40% CXRs resulted in interventions; adjustment in ventilator settings (13.5%) was the most frequent intervention. In 26% (n = 138) of radiographs, image quality required improvement. One or more additional body part exposure other than chest and upper abdomen were noted 336 (64%) images. Children with > 3 CXR had higher PRISM III score, more often mechanically ventilated, had higher number of indwelling devices [mean (SD) 2.6 (1.2) vs. 1.7 (1.0)] and stayed longer in PICU [median (IQR) 11(7.5-18.5) vs. 6 (3-9)]. CONCLUSION: On demand prescription was the prevalent practice in our PICU. Most non-ventilated children underwent only one CXR while duration of PICU stay and the number of devices determined the number of CXRs in mechanically ventilated children. Quality improvement strategies should concentrate on the process of acquisition of images and limiting the radiation exposure to unwanted body parts.

Fungaemia due to rare yeasts in paediatric intensive care units: A prospective study.

BACKGROUND: Considering the emergence of fungaemia due to rare yeasts at our centre, we performed a systematic epidemiologic study on fungaemia due to rare yeast. OBJECTIVES: We undertook the present prospective observational study to explore the epidemiological features and clinical characteristics of fungaemia due to rare yeasts in paediatric ICUs at our centre. METHODS: The successive yeasts isolated from blood at our PICUs during December 2017 through March 2019 were identified by molecular methods. Fungaemia due to yeasts other than C. albicans, C. tropicalis, C. glabrata, C. krusei and C. parapsilosis was categorised as rare yeasts. Antifungal susceptibility testing of the yeast isolates was performed as per clinical and laboratory standards institute (CLSI) guidelines. We also compared different clinical parameters of fungaemia due to common versus rare yeasts, and rare yeasts in neonates versus non-neonates. RESULTS: During the study period, 212 yeast isolates were obtained from 159 patients at PICUs of our hospital, and 127 isolates from 98 patients (61.6%) were categorised as rare yeasts. Neonates acquired fungaemia significantly earlier after ICU admission than non-neonates (median:4 vs 6 days; p = .005). Regarding epidemiology study of rare yeast fungaemia, Wickerhamomyces anomalus (43.8%) and Candida utilis (40.8%) were common isolates; surgical intervention and gastrointestinal disease were significantly associated; overall, azole, echinocandin and amphotericin B resistance was at 9.1%, 1.02% and 1.02%, respectively; overall mortality was 65.3%. CONCLUSIONS: The emergence of rare yeasts especially W. anomalus and C. utilis causing fungaemia in our children demands urgent attention to control the spread.

Cost analysis of pediatric intensive care: a low-middle income country perspective.

BACKGROUND: Globally, Pediatric Intensive Care Unit (PICU) admissions are amongst the most expensive. In low middle-income countries, out of pocket expenditure (OOP) constitutes a major portion of the total expenditure. This makes it important to gain insights into the cost of pediatric intensive care. We undertook this study to calculate the health system cost and out of pocket expenditure incurred per patient during PICU stay. METHODS: Prospective study conducted in a state of the art tertiary level PICU of a teaching and referral hospital. Bottom-up micro costing methods were used to assess the health system cost. Annual data regarding hospital resources used for PICU care was collected from January to December 2018. Data regarding OOP was collected from 299 patients admitted from July 2017 to December 2018. The latter period was divided into four intervals, each of four and a half months duration and data was collected for 1 month in each interval. Per patient and per bed day costs for treatment were estimated both from health system and patient's perspective. RESULTS: The median (inter-quartile range, IQR) length of PICU stay was 5(3-8) days. Mean ± SD Pediatric Risk of Mortality Score (PRISM III) score of the study cohort was 22.23 ± 7.3. Of the total patients, 55.9% (167) were ventilated. Mean cost per patient treated was US$ 2078(₹ 144,566). Of this, health system cost and OOP expenditure per patient were US$ 1731 (₹ 120,425) and 352 (₹ 24,535) respectively. OOP expenditure of a ventilated child was twice that of a non- ventilated child. CONCLUSIONS: The fixed cost of PICU care was 3.8 times more than variable costs. Major portion of cost was borne by the hospital. Severe illness, longer ICU stay and ventilation were associated with increased costs. This study can be used to set the reimbursement package rates under Ayushman Bharat - Pradhan Mantri Jan Arogya Yojana (AB-PMJAY). Tertiary level intensive care in a public sector teaching hospital in India is far less expensive than developed countries.

Intensive Care Unit-Acquired Weakness in Children: A Prospective Observational Study Using Simplified Serial Electrophysiological Testing (PEDCIMP Study).

BACKGROUND: To study the incidence and time of onset of intensive care unit-acquired weakness in a prospective cohort of children (2-12 years) by serial simplified electrophysiological assessment (Pediatric Critical Illness Myopathy Polyneuropathy study, PEDCIMP). METHODS: A single-center, prospective cohort study (Trial Registry Number: NCT02763709; PEDCIMP2016) was conducted at the pediatric intensive care unit of a tertiary care hospital in North India. A complete electrophysiological evaluation (4 motor nerves and 2 sensory nerves) was performed at baseline in children (2-12 years) admitted to the ICU with a pediatric risk of mortality (PRISM) of > 20 with more than 24-h stay. Following the entry evaluation, a minimal alternate day simplified electrophysiological testing of the unilateral common peroneal nerve and the sural nerve was assessed. A 25% reduction in compound muscle action potential (CMAP) and sensory nerve action potential from baseline was considered significant for ICUAW and was confirmed by complete electrophysiological re-evaluation. RESULTS: Of the total 481 children assessed for eligibility, 97 were enrolled. The median age of the cohort was 7 years. Sepsis (81%); need for vasoactive support (43%); multiorgan dysfunction (26%) were the common reasons for admission. Of the 433 eligible patient ICU days, 380 electrophysiological observations were done. A significant decrease of > 25% in CMAP of common peroneal nerve was not detected in any of the 380 observations. However, two children unfit for inclusion were diagnosed with ICUAW during the study period. CONCLUSIONS: Children admitted with PRISM > 20 have a very low incidence of intensive care unit-acquired weakness by serial clinical and abbreviated electrophysiological evaluation.

Thiamine Status in Children with Septic Shock from a Developing Country: A Prospective Case-Control Study.

OBJECTIVE: Mitochondrial dysfunction is central to sepsis-induced multi-organ dysfunction. Thiamine deficiency may contribute to mitochondrial dysfunction and thus high mortality. Study was planned to assess thiamine status in children with septic shock in comparison to healthy controls from a developing country and to study the effect of thiamine levels on its outcome. METHODS: A prospective case-control study (April 2017 to May 2018) enrolling consecutive children with septic shock as 'cases' (n = 76), their healthy siblings (n = 51) and apparently healthy children from immunization clinic (n = 35) as 'controls'. Whole blood total thiamine (WBTT) level was measured on days 1, 10 and 1-month post-discharge. Outcome parameters were acute care area free days on days 14 and 28, and mortality. RESULTS: WBTT [nMol/l; median (interquartile range, IQR)] was significantly lower on day 1 in cases compared with sibling controls [23.1 (21.8-26.3) vs. 36.9 (33.6-40.5); p < 0.001]. It fell further on day 10 [20.8 (18.1-21.1); p < 0.02]. Levels rose significantly 1-month post-discharge [35.5 (31.2-36.6)] and became comparable to sibling controls (p = 0.4). Immunization clinic controls also had lower WBTT [42.3 (40.1-45.9)], but was significantly higher than sibling controls and cases at 1-month post-discharge (p < 0.001). Survivors and non-survivors of septic shock were similar. WBTT levels did not correlate with any of the severity indicators of septic shock or its outcomes. CONCLUSIONS: WBTT was significantly low in all children, and fell further during septic shock. Observed severe deficiency might have precluded any further association of thiamine levels with severity of septic shock and its outcome. Data obtained may inform trials on metabolic resuscitation in paediatric septic shock in developing countries. Lay summaryThiamine deficiency may contribute to high mortality in paediatric septic shock as thiamine is an essential factor for functioning of mitochondria, the powerhouse of the cells. This prospective case-control study was conducted to assess thiamine status in children with septic shock in comparison with healthy controls in a developing country. Consecutive children with fluid-refractory septic shock were enrolled as 'cases'. Their apparently healthy siblings, and apparently healthy children from immunization clinic, were enrolled as 'controls'. The whole blood total thiamine (WBTT) level was measured on days 1, 10 and 1 month after hospital discharge. Seventy-six children were enrolled as cases, 51 children as sibling controls and 35 children as immunization clinic controls. WBTT was significantly lower on day 1 in cases as compared with their sibling controls. It fell further on day 10. The level rose significantly after a month of discharge and became comparable to sibling controls. Immunization clinic controls also had lower WBTT but was significantly higher compared with sibling controls and cases at 1-month post-discharge. Survivors and non-survivors of septic shock had similar WBTT levels. Observed severe deficiency might have precluded any further association of thiamine levels with septic shock outcome.

Intensive Care Needs and Short-Term Outcome of Multisystem Inflammatory Syndrome in Children (MIS-C): Experience from North India.

OBJECTIVES: To describe the intensive care needs and outcome of multisystem inflammatory syndrome in children (MIS-C). METHODOLOGY: This retrospective study was conducted in the pediatric emergency, pediatric intensive care unit (PICUs) and the coronavirus disease 2019 (COVID 19) hospital of a tertiary teaching and referral hospital in North India over a period of 5 months (September 2020 to January 2021). Clinical details, laboratory investigations, intensive care needs, treatment and short-term outcome were recorded. RESULTS: Forty children with median interquartile range age of 7 (5-10) years were enrolled. The common clinical features were fever (97.5%), mucocutaneous involvement (80%), abdominal (72.5%) and respiratory (50%) symptoms. Shock was noted in 80% children. Most cases (85%) required PICU admission where they received nasal prong oxygen (40%), non-invasive (22.5%) and invasive (22.5%) ventilation and vasoactive drug support (72.5%). The confirmation of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) exposure was in the form of positive serology (66.7%), reverse transcriptase polymerase chain reaction (10%), and contact with SARS-CoV-2 positive case (12.5%). The common echocardiographic findings included myocardial dysfunction (ejection fraction <55%; 72.5%), and coronary artery dilatation or aneurysm (22.5%). The immunomodulatory treatment included intravenous immunoglobulin (2 g/kg) (100%) and steroids (methylprednisolone 10-30 mg/kg/day for 3-5 days) (85%). Aspirin was used in 80% and heparin (low molecular weight) in 7.5% cases. Two children died (5%) and median duration of PICU and hospital stay in survivors were 5 (2-8) and 7 (4-9) days, respectively. Children with shock showed higher total leucocyte count and higher rates of myocardial dysfunction. CONCLUSION: Cardiovascular involvement and shock are predominant features in severe disease. Early diagnosis can be challenging given the overlapping features with other diagnoses. A high index of suspicion is warranted in children with constellation of fever, mucocutaneous, gastrointestinal and cardiovascular involvement alongwith evidence of systemic inflammation and recent or concurrent SARS-CoV-2 infection. The short-term outcome is good with appropriate organ support therapies and immunomodulation.

Quality Improvement Initiative to Reduce Intravenous Line-related Infiltration and Phlebitis Incidence in Pediatric Emergency Room.

AIM AND OBJECTIVE: To reduce the incidence of infiltration and phlebitis by 50% over 2 months among children admitted to the emergency room (ER) of a tertiary care hospital. MATERIALS AND METHODS: The study was conducted in the pediatric ER of a tertiary care hospital in North India. All children aged >28 days, receiving intravenous (IV) medication and/or fluids, were enrolled between June (2017) and September (2017). Existing practices of IV line insertion and maintenance were observed and recorded. The visual infusion phlebitis score and infiltration assessment scale were to grade the extent of two. The intervention classified as "IV line insertion and maintenance bundle" included the introduction of low-cost mobile sterile compartment trays, audit and feedback, organizational change, introduction of infection control nurse and quality improvement (QI) team formations were implement in different Plan-Do-Study-Act (PDSA) cycles. Reduction in the "incidence of phlebitis and infiltration" was outcome measures while "scores on checklist of IV line insertion and IV line maintenance and administration of drugs" were process measures. RESULT: The process measures, for IV line insertion, maintenance and administration of drugs through IV line, revealed an increase in scores on the checklist. There was a significant decrease in the incidence of infiltration and phlebitis from 82.9 and 96.1% to 45 and 55%, respectively, postimplementation of all PDSA cycles. CONCLUSION: Multifaceted QI IV line insertion and maintenance bundle reduced the incidence of infiltration and phlebitis. These interventions when integrated into daily work bundles along with continuous education and motivation help in sustaining the goal and attaining long-term success.
