Objectives: Mortality from pneumonia is three times higher in Asia compared with industrialized countries. We aimed to determine the epidemiology, microbiology, and outcome of severe pneumonia in PICUs across the Pediatric Acute and Critical Care Medicine Asian Network (PACCMAN)., Design: Prospective multicenter observational study from June 2020 to September 2022., Setting: Fifteen PICUs in PACCMAN., Patients: All children younger than 18 years old diagnosed with pneumonia and admitted to the PICU., Interventions: None., Measurements and Main Results: Clinical, microbiologic, and outcome data were recorded. The primary outcome was PICU mortality. Univariate and multivariable logistic regression was performed to investigate associations between PICU mortality and explanatory risk factors on presentation to the PICU. Among patients screened, 846 of 11,778 PICU patients (7.2%) with a median age of 1.2 years (interquartile range, 0.4-3.7 yr) had pneumonia. Respiratory syncytial virus was detected in 111 of 846 cases (13.1%). The most common bacteria were Staphylococcus species (71/846 [8.4%]) followed by Pseudomonas species (60/846 [7.1%]). Second-generation cephalosporins (322/846 [38.1%]) were the most common broad-spectrum antibiotics prescribed, followed by carbapenems (174/846 [20.6%]). Invasive mechanical ventilation and noninvasive respiratory support was provided in 438 of 846 (51.8%) and 500 of 846 (59.1%) patients, respectively. PICU mortality was 65 of 846 (7.7%). In the multivariable logistic regression model, age (adjusted odds ratio [aOR], 1.08; 95% CI, 1.00-1.16), Pediatric Index of Mortality 3 score (aOR, 1.03; 95% CI, 1.02-1.05), and drowsiness (aOR, 2.73; 95% CI, 1.24-6.00) were associated with greater odds of mortality., Conclusions: In the PACCMAN contributing PICUs, pneumonia is a frequent cause for admission (7%) and is associated with a greater odds of mortality., Competing Interests: Drs.

Enteric fever is an endemic disease in developing and low-middle income countries due to poor sanitation and hygiene. The majority of cases have mild symptoms and resolve with oral or intravenous antibiotics. However, multisystemic involvement due to enteric fever requiring intensive care is not uncommon and is associated with high mortality and morbidity. We report a 5-year-old boy from Mohali, Punjab, India with enteric fever who had fulminant course with several complications including transient intussusception, myocardial dysfunction, encephalopathy, and secondary hemophagocytic lymphohistiocytosis. He was treated with ceftriaxone, vasoactive drugs, mechanical ventilation, dexamethasone, and intravenous immunoglobulin and had favorable outcome despite life-threatening complications.

Background: Sepsis associated acute kidney injury (AKI) is linked with adverse outcomes in the PICU. Doppler-based renal resistive index (RRI) has shown promising results in adults for prediction of AKI. We aimed to explore the performance of RRI in children with sepsis., Methods: This prospective observational study (March - November 2022) included children aged 1-12 years with sepsis admitted to the PICU. RRI and urine neutrophil gelatinase associated lipocalin (NGAL) were measured within 12 h of admission. Children were followed up for 3 days. AKI (new and persistent) was defined as any child with KDIGO stage 2 or 3 AKI on day 3., Results: We enrolled 90 children but included 79 in final analysis. Two thirds (n = 53, 67%) had septic shock. Median (IQR) age was 6.2 years (4.1-9.2). RRI decreased with increasing age. Twenty-six (33%) children had AKI on day 3. Mean (SD) RRI was higher in the AKI group [0.72 (0.08) vs. 0.65 (0.07), p < 0.001].The area under ROC curve for RRI to detect AKI among the 1-4 year old group was 0.75 (95% CI:0.51, 0.98; p = 0.05) and among the 5-12 year old group was 0.76 (0.62, 0.89; p = 0.001). An RRI 0.71 predicted AKI with 100% sensitivity and 46.2% specificity among the 1-4-year-old group and RRI 0.69 predicted it with 70% sensitivity and 77.5% specificity in the 5-12-year-old group. RRI and eGFR at admission were independent predictors of AKI on multivariable analysis. Urine NGAL 94.8 ng/ml predicted AKI with 76.9% sensitivity and 77.4% specificity and AUROC was 0.74 (0.62, 0.86) among the 1-12-year-old group., Conclusions: RRI values varied with age. RRI showed good diagnostic accuracy to detect new/persistent AKI on day 3 in children with sepsis; however, it was less precise as an independent predictor., (© 2024.

Objectives: To study the impact of high flow nasal cannula (HFNC) vs. conventional oxygen therapy (COT) (by simple nasal cannula) as respiratory support after extubation on the rates of post-extubation airway obstruction (PEAO) among mechanically ventilated critically ill children., Methods: This open-label randomized controlled trial was conducted in pediatric intensive care unit (PICU) of a tertiary care teaching hospital in North India over a period of 7 mo (11 August 2021 to 10 March 2022). Children aged 3 mo to 12 y who required invasive mechanical ventilation for > 72 h and had passed spontaneous breathing trial (ready for extubation) were enrolled and randomized by computer generated block randomization to receive HFNC or COT after extubation. Primary outcome was rate of PEAO (assessed by modified Westley croup score, mWCS) within 48 h of extubation; and secondary outcomes were rate and number of adrenaline nebulization, treatment failure (requiring escalation of respiratory support), extubation failure, adverse events, and length of PICU stay in two groups., Results: During the study period, 116 children were enrolled (58 each in HFNC and COT groups). There was no difference in rate of PEAO (55% vs. 51.7%, respectively), need of adrenaline nebulization, extubation failure, adverse events, and duration of PICU stay in two groups. However, the HFNC group had significantly lower rates of treatment failure (27.6% vs. 48.3%, p = 0.02)., Conclusions: The rate of PEAO was similar in HFNC and COT groups. However, HFNC group had significantly lower rate of treatment failure requiring escalation of respiratory support., (© 2024. The Author(s), under exclusive licence to Dr. K C Chaudhuri Foundation.)

Respiratory samples from 139 hospitalized children were screened for the human bocavirus (HBoV) genome. Positive samples were sequenced for the partial VP1/VP2 gene followed by molecular and phylogenetic analyses. HBoV positivity was noted in 7.2% (10/139) of patients. All HBoV-positive children presented with fever, cough, and respiratory distress (90%, 9/10). Three children developed multisystemic viral illness, with one fatality. Eight children required intensive care management and five required mechanical ventilation. The nucleotide percent identity of the partial VP1/VP2 gene in the HBoV study strains ranged from 97.52% to 99.67%. Non-synonymous mutations in the VP1 protein were T591S (n = 8) and Y517S (n = 1) in the HBoV St1 strain and N475S (n = 8) and S591T (n = 2) in the HBoV St2 strain. One strain showed A556P, H556P, I561S, and M562R non-synonymous mutations. All the study strains belonged to the HBoV1 type. Seven HBoV strains belonged to the same lineage, and three belonged to another lineage. For evolutionary dynamics, GTR+I substitution model with uncorrelated relaxed lognormal clock and Bayesian Skyline tree prior showed 9.0 × 10 -4 (95% highest probability density interval: 3.1 × 10 -6 , 2.1 × 10 - 3) nucleotide substitutions per site per year. Clinical suspicion and virological screening are necessary to identify HBoV infections in children.

Objectives: To compare clinical, neurological, treatment and outcome of recurrent Guillian-Barré Syndrome (GBS) with non-recurrent GBS. Also, to compare different episodes of recurrent GBS., Methods: The patient's case records were retrieved retrospectively from the electronic database and case record files. Clinical profile, nerve conduction study, treatment, and outcome details of children with a diagnosis of GBS admitted in Pediatric Intensive Care Unit (PICU) from 2010 to March 2022 were screened. Recurrent GBS cases, as defined by the National Institute of Neurological and Communicative Diseases and Strokes (NINCDS) criteria, were analysed separately. The comparison was made between the first episode of recurrent GBS with non-recurrent GBS, and predictors of recurrence were identified. A comparison of course and outcome was also done between different episodes of GBS in recurrent cases., Results: Recurrent GBS was observed in 11 (4.7%) out of 234 cases during the study period. The presence of respiratory (p 0.015) and gastrointestinal illness (p 0.007) as preceding illnesses were associated with recurrence. No difference was noted between the first episode of recurrent GBS and non-recurrent GBS. The first and second episodes of GBS in 11 recurrent cases were similar in course and outcome., Conclusions: Recurrent GBS is underreported but a known entity. No difference was seen between the two episodes of recurrent GBS. However, more data is required to find the features of recurrent GBS so that limited PICU resources can be used judiciously and intervention planned accordingly., (© 2023.

Objectives: To study the epidemiology of non-coronavirus disease-2019 (non-COVID-19) respiratory viral infections with respect to their clinical profile, intensive care needs and predictors of outcome once the non-pharmacological interventions (NPI) during the coronavirus disease-2019 (COVID-19) pandemic were relaxed., Methods: Retrospective analysis of children with Severe Acute Respiratory Illness (SARI) who were SARS-CoV-2 negative, admitted to the Pediatric Emergency/Intensive Care Unit (PICU) from July 2021 through October 2021 was conducted., Results: One hundred and thirty nine children with median age of 11 (4-28.5) mo were included. Besides respiratory symptoms in all, diarrhea was reported in 90 (64.7%) children. Nearly half (n = 66; 47%) presented in hypoxemic respiratory failure (SpO 2 <88%). Fifty-two (37.4%) children had co-morbidities, commonest being congenital heart disease in 12 (23.1%). Baseline parameters revealed leukopenia (specifically lymphopenia) 39 (28%), elevated aspartate transaminase [Serum glutamic-oxaloacetic transaminase (SGOT)] in 108 (77.6%), elevated N-acetyl-cysteine-activated creatinine kinase (CK-NAC) 23 (79%) and lactate dehydrogenase (LDH) 15 (88%). Intensive care needs included mechanical ventilation 51 (36.6%), vasoactive support 34 (24.5%), and renal replacement therapy 10 (7.1%). Forty-two (30.2%) children developed multi-organ dysfunction syndrome (MODS). One hundred and three (74.1%) children were discharged, 31 (22.3%) died, and 5 (3.6%) left against medical advice. On multivariate regression analysis, elevated liver enzymes (>5 times normal), hypoxemic respiratory failure at admission, hypotensive shock and MODS predicted mortality., Conclusions: A surge in non-COVID SARI was observed once lockdown measures were relaxed. Nearly 1/3 rd progressed to multi-organ failure and died. Elevated liver enzymes, hypoxemic respiratory failure at admission, hypotensive shock and MODS predicted death., (© 2023.

Objectives: To assess the pattern of fluid overload (FO) and its impact on mortality among mechanically ventilated children., Methods: In this secondary analysis of an open-label randomized controlled trial (ReLiSCh trial, October 2020-September 2021), hemodynamically stable mechanically ventilated children (n = 100) admitted to a tertiary level pediatric intensive care unit (PICU) in North India were enrolled. The primary outcome was pattern of FO (FO% >10% and cumulative FO% from day 1-7); and secondary outcomes were pattern of FO among survivors and non-survivors, and prescription practices of maintenance fluid., Results: The median (IQR) age was 3.5 (0.85-7.5) y and 57% were males. Common diagnoses were pneumonia (27%), scrub typhus (14%), Landry-Guillain-Barré syndrome (9%), dengue (8%), central nervous system infections (7%) and staphylococcal sepsis (6%). Common organ dysfunction included acute respiratory distress syndrome (ARDS) (41%), shock (38%), and acute kidney injury (AKI) (9%). The duration PICU stay was 11 (7-17) d and mortality was 12%. The FO% >10% was noted in 19% children; and there was significant increase in cumulative FO% from day 1-7 [1.2 (0.2-2.6)% to 8.5 (1.7-14.3)%, (p = 0.000)]. Among non-survivors, higher proportion had FO% >10% (66.7% vs. 12.5%, p 0.0001); and trend towards higher cumulative FO% on first seven days. From day 1-7, the percentage of maintenance fluid received increased from 60 (50-71)% to 70 (60-77)% (p = 0.691)., Conclusions: One-fifth of mechanically ventilated children had FO% >10% and there was significant increase in cumulative FO% from day 1-7. Non-survivors had significantly higher degree of FO., (© 2024. The Author(s), under exclusive licence to Dr. K C Chaudhuri Foundation.)

Objectives: To investigate the diagnostic accuracy of three-point ultrasonography for confirmation of endotracheal tube (ETT) position among children undergoing endotracheal intubation (ETI) with chest radiograph as reference standard., Methods: This prospective observational study was conducted from January 2021 through December 2021 (12 mo) in the pediatric emergency room (PER) and pediatric intensive care unit (PICU), Division of Pediatric Critical Care, Advanced Pediatrics Centre (APC), Post-Graduate Institute of Medical Education and Research (PGIMER), Chandigarh, India. Children aged 3 mo to 12 y, undergoing ETI in PER or PICU were included. Three-point ultrasonography (suprasternal notch and bilateral anterior chest) was done following ETI for confirmation of correct ETT position. Chest radiograph was used as a reference standard. Interobserver agreement between two investigators (IG and SKA) (kappa statistic) was determined for three-point ultrasonography to confirm the correct ETT position., Results: One hundred fifty-five children with median (IQR) age of 4.5 (1-7) y were enrolled; 60% (n = 94) were males. On neck ultrasound, bilaminar sign was present in 100% of children. On lung ultrasound, bilateral and unilateral pleural sliding were present in 97.4% and 2.6% children, respectively. Three-point ultrasonography identified the correct position of ETT in 97.4% children as compared to 83.2% on chest radiograph. Sensitivity of three-point ultrasonography to identify the correct position of ETT was 98%. The interobserver agreement between two examiners was 96.8% (kappa of 0.53, p = 0.000)., Conclusions: Three-point ultrasonography is an effective, sensitive, safe, and reproducible bedside method for identification of correct placement of ETT in children admitted to PER and PICU., (© 2024.

Objectives: To assess the efficacy and safety of bicarbonate infusion in children with Acute Diarrhea and Severe Dehydration (ADSD) having severe Non-Anion Gap Metabolic Acidemia (sNAGMA)., Methods: Children (aged 1-144 mo) with ADSD and sNAGMA (pH ≤7.2 and/or serum bicarbonate ≤15 mEq/L) were enrolled in an open-label randomized design. Controls (n = 25) received WHO-recommended rehydration therapy with Ringer Lactate, while intervention group (n = 25) received additional bicarbonate deficit correction. Primary outcome was time taken to resolve metabolic acidemia (pH >7.30 and/or bicarbonate >15 mEq/L). Secondary outcome measures were adverse outcome [composite of pediatric intensive care unit (PICU) transfer and deaths], acute care area free days in 5 d (ACAFD 5 ), hospital stay, and adverse effects., Results: Time taken to resolve metabolic acidemia was significantly lesser with intervention [median (IQR); 8 h (4, 12) vs. 12 h (8, 24); p = 0.0067]. Intervention led to acidemia resolution in significantly more children by 8 h and 16 h (17/25 vs. 9/25, p = 0.035 and 23/25 vs. 17/24, p = 0.018, respectively). Patients with fluid refractory shock needed lesser inotropes in intervention group [median Vasoactive Inotrope Score (VIS), 10.5 vs. 34]. Intervention led to significantly lesser adverse outcome (0/25 vs. 5/25, p = 0.049), and noticeably more ACAFD 5 [median (IQR); 2 (1, 2) vs. 1 (1, 2); p = 0.12]. Two patients died in the control group while none in the intervention group. No adverse effect was documented., Conclusions: Additional calculated dose of bicarbonate infusion led to significantly early resolution of metabolic acidemia, lesser utilization of critical care facilities, and lesser adverse outcome in children with ADSD and sNAGMA, compared to standard therapy, with no adverse effect., (© 2023.

Objectives: To investigate the barriers and facilitators involved in the back-referral process of newborns from a tertiary care centre to district Special Newborn Care Units (SNCUs) for step-down care., Methods: The study employed mixed methods, including feedback questionnaires for parents of back-referred neonates, in-depth interviews with doctors and nurses from six SNCUs, and focused group discussions with medical staff at a tertiary-level institute. The study was conducted over a period of seven and a half months in a north Indian tertiary care centre., Results: The back-referral process received positive acceptance from parents and healthcare personnel. Notable barriers included the lack of Retinopathy of Prematurity (ROP) screening services in some SNCUs, inadequate free transport facilities for back-referral, and deficiencies in two-way communication. Parents provided valuable feedback for improvement, suggesting back-referral to the SNCU nearest to their home, daytime back-referral with adequate prior notice, and the availability of post-partum obstetric care at SNCUs for the mother. Inadequate environmental hygiene and limited availability of ROP services were identified as concerns. Facilitators included effective communication, proximity-based back-referral, and ongoing mentoring of SNCUs by tertiary centres., Conclusions: Establishing efficient two-way communication between tertiary centres and district SNCUs, provision of essential facilities at SNCUs, and ensuring a seamless continuum of care are pivotal for successful back-referral of convalescent neonates. Addressing these factors can contribute to improving the back-referral process, level 3 bed availability at the tertiary centres and neonatal health outcomes., (© 2023.

Objectives: To assess the impact of restricted vs. usual/liberal maintenance fluid strategy on fluid overload (FO) among mechanically ventilated children., Methods: This open-label randomized controlled trial was conducted over a period of 1 y (October 2020-September 2021) in a Pediatric intensive care unit (PICU) in North India. Hemodynamically stable mechanically ventilated children were randomized to 40% (restricted group, n = 50) and 70-80% (usual/liberal group, n = 50) of maintenance fluids. The primary outcome was cumulative fluid overload percentage (FO%) on day 7. Secondary outcomes were FO% >10%; vasoactive inotropic score, sequential organ failure assessment score, pediatric logistic organ dysfunction score and oxygenation index from day 1-7; ventilation free days (VFDs) and PICU free days (PFDs) through day 28; and mortality., Results: The restricted group had statistically non-significant trend towards lower cumulative FO% at day 7 [7.6 vs. 9.5, p = 0.40]; and proportion of children with FO% >10% (12% vs. 26%, p = 0.21) as compared to usual/liberal group. The increase in FO% from day 1-7 was significant in usual/liberal group as compared to restricted group (p <0.001 and p = 0.134, respectively). Restricted group received significantly lower amount of fluid in the first 5 d; had significantly higher VFDs (23 vs. 17 d, p = 0.008) and PFDs (19 vs. 15 d, p = 0.007); and trend towards lower mortality (8% vs. 16%, p = 0.21)., Conclusions: Restricted as compared to usual/liberal maintenance fluid strategy among mechanically ventilated children was associated with a trend towards lower rate and severity of FO and mortality; and significantly lower fluid volume received, and higher VFDs and PFDs., (© 2023.

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., (© 2023 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Introduction: Acute lower respiratory tract infections (ALRTIs) are the commonest cause of mortality in children mostly attributed to respiratory viruses. During the coronavirus disease 2019 (COVID-19) pandemic, the dynamics and transmission of infections changed worldwide due to widespread public health measures. This study aimed to understand the pattern of respiratory viruses associated with ALRTIs in children pre and during COVID-19 pandemic in India., Methodology: Respiratory samples were collected from ALRTI patients during pre-pandemic period (October 2019 to February 2020; n = 166), Delta (July 2021 to December 2021; n = 78) and Omicron wave (January 2022 to July 2022; n = 111). Samples were screened for Influenza (Inf) A pdmH1N1, InfA H3N2, InfB, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), human bocavirus (hBoV), human rhinovirus (hRV), and parainfluenza virus (PIV-2 and PIV-3) by nucleic acid amplification techniques (NAATs)., Results: Significantly higher proportion of children with ALRTIs had virus/es isolated during pre-pandemic period than during mid-pandemic period [78.9% (131/166) vs. 52.9% (100/189); p < 0.001). RSV positivity was significantly higher (51.2%) in pre-pandemic period than 10.3% and 0.9% during the Delta and Omicron waves respectively. No significant difference in positivity rate of Inf A pdmH1N1, Inf A H3N2 and Inf B was seen. The increase in positivity of hRV (39.2% vs 42.3% vs 56.8%) and hBOV (1.2% vs 5.1% vs 9%) was documented in pre-pandemic, delta wave and omicron wave respectively., Conclusions: The COVID-19 pandemic significantly impacted the frequency and pattern of respiratory viruses among hospitalized children with ALRTIs in India., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2023 Mannat Kang, Subhabrata Sarkar, Suresh Kumar Angurana, Pankaj Singh, Meenakshi Rana, Ishani Bora, Rishi Chetanya, Bharatendu Singh, Jayashree Muralidharan, Radha Kanta Ratho.)

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., Competing Interests: Dr. Sankhyan disclosed that he is the site principal investigator (PI) for a funded international multicentric trial on treatment of tuberculous meningitis in children (Short intensive treatment for children with tuberculous meningitis, the “SURE trial”), which is being coordinated by the University College London and is an investigator-initiated academic trial. He is also the site PI for a pharmaceutical-sponsored (PTC United States) trial on Ataluren in Duchenne muscular dystrophy. The remaining authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2023 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.)

Objective: Multisystem inflammatory syndrome (MIS-C) in children is a febrile illness that has overlapping presentation with other locally prevalent illnesses. Clinicolaboratory profile of children admitted with MIS-C and dengue were compared to understand their presentation at the outset., Methods: This was a retrospective study of children ≤ 12 y admitted with MIS-C (WHO definition) or laboratory-confirmed dengue between August 2020 and January 2021 at a tertiary center in North India., Results: A total of 84 children (MIS-C - 40; dengue - 44) were included. The mean (SD) age [83.5 (39) vs. 91.6 (35) mo] was comparable. Rash (72.5% vs. 22.7%), conjunctival injection (60% vs. 2.3%), oral mucocutaneous changes (27.5% vs. 0) and gallop rhythm (15% vs. 0) were seen more frequently with MIS-C, while petechiae [29.5% vs. 7.5%], myalgia (38.6% vs. 10%), headache (22.7% vs. 2.5%), and hepatomegaly (68.2% vs. 27.5%) were more common with dengue. Children with MIS-C had significantly higher C-reactive protein (124 vs. 3.2 mg/L) and interleukin 6 (95.3 vs. 20.7 ng/mL), while those with dengue had higher hemoglobin (12 vs. 10.2 g/dL) lower mean platelet count (26 vs. 140 × 10 9 /L), and greater elevation in aspartate (607 vs. 44 IU/L) and alanine (235.5 vs. 56 IU/L) aminotransferases. The hospital stay was longer with MIS-C; however, PICU stay and mortality were comparable., Conclusion: In hospitalized children with acute febrile illness, the presence of mucocutaneous features and highly elevated CRP could distinguish MIS-C from dengue. The presence of petechiae, hepatomegaly, and hemoconcentration may favor a diagnosis of dengue., (© 2022. The Author(s), under exclusive licence to Dr. K C Chaudhuri Foundation.)

Background: Pressure support (PS) as a spontaneous breathing trial (SBT) was considered inferior to continuous positive airway pressure (CPAP) and T-piece because PS underestimated post-extubation work of breathing in physiologic studies. We aimed to compare PS and CPAP as SBT methods for assessing clinical outcomes in children., Methods: This was an open label randomized non-inferiority trial conducted between December 2019 and August 2021 among children aged 1 month to 12 years deemed ready for weaning after at least 48 h of invasive ventilation in PICU. Children were randomized to undergo a 2-h SBT with PS of 8 cm H 2 O in addition to PEEP 5-6 cm H 2 O or CPAP (5-6 cm H 2 O). The primary outcome was successful liberation from invasive ventilation for 72 h after first SBT. Secondary outcomes included first SBT pass rate, need for post-extubation respiratory support (high flow oxygen and/or non-invasive ventilation), and length of PICU stay., Findings: Of the 247 enrolled children, 244 completed the trial (121 in PS and 123 in CPAP group). Median (IQR) age was 24 (9, 84) months. Median (IQR) duration of invasive ventilation before randomization was 4.5 (3, 6.5) days. Successful liberation from invasive ventilation after first SBT occurred in 97 (80.2%) children in PS and 93 (75.6%) children in CPAP group [difference 4.6; 95% CI (-5.8, 15); p = 0.39]. First SBT pass rate between PS and CPAP [111 (91.7%) versus 105 (85.4%); difference 6.3; 95% CI (-1.6, 14.3); p = 0.12] was similar. Need for post-extubation respiratory support [52 (43%) versus 49 (40%)], rate of reintubation within 72 h [14 (11.6%) versus 12 (9.8%)] and median (IQR) length of PICU stay [9 (6, 15) versus 8 (5.5, 13) days] were comparable. Four (1.6%) children, all in CPAP group had unfavourable outcome (1 died, 3 discontinued care)., Interpretation: In invasively ventilated children, 2-h SBT with pressure support was non-inferior to CPAP in predicting successful liberation from invasive ventilation., Funding: None., Competing Interests: All authors declare no competing interests., (© 2023 The Author(s).)

Objective: To describe the clinical and laboratory profile, management, intensive care needs, and outcome of children with toxic shock syndrome (TSS) admitted to the pediatric intensive care unit (PICU) of a tertiary care center in North India., Methods: This retrospective study was conducted in the PICU of a tertiary care hospital in North India over a period of 10 y (January 2011-December 2020) including children < 12 y with TSS (n = 63)., Results: The median (interquartile range, IQR) age was 5 (2-9) y, 58.7% were boys, and Pediatric Risk of Mortality III (PRISM-III) score was 15 (12-17). The primary focus of infection was identified in 60.3% children, 44.5% had skin and soft tissue infections, and 17.5% (n = 11) had growth of Staphylococcus aureus. Common manifestations were shock (100%), rash (95.2%), thrombocytopenia (79.4%), transaminitis (66.7%), coagulopathy (58.7%), and acute kidney injury (AKI) (52.4%); and involvement of gastrointestinal (61.9%), mucus membrane (55.5%), respiratory (47.6%), musculoskeletal (41.3%), and central nervous system (CNS) (31.7%). The treatment included fluid resuscitation (100%), vasoactive drugs (92.1%), clindamycin (96.8%), intravenous immunoglobulin (IVIG) (92.1%), blood products (74.6%), mechanical ventilation (58.7%), and renal replacement therapy (31.7%). The mortality was 27% (n = 17). The duration of PICU and hopsital stay was 5 (4-10) and 7 (4-11) d, respectively. Higher proportion of nonsurvivors had CNS involvement, transaminitis, thrombocytopenia, coagulopathy, and AKI; required mechanical ventilation and blood products; and had higher vasoactive-inotropic score., Conclusion: TSS is not uncommon in children in Indian setup. The management includes early recognition, intensive care, antibiotics, source control, and adjunctive therapy (IVIG and clindamycin). Multiorgan dysfunction and need for organ supportive therapies predicted mortality., (© 2022. The Author(s), under exclusive licence to Dr. K C Chaudhuri Foundation.)

Background: Most children with Guillain-Barré syndrome (GBS) recover but may suffer from long-term sequelae, interfering with development and quality of life. Owing to the lack of published data, we aimed to assess the long-term neurological, behavioral, functional, quality of life, and school performance outcomes them., Methods: Design: Cross-sectional observational., Setting: Pediatric intensive care unit., Patients: Children, aged one to 12 years, with GBS admitted over five years (July 2012 to June 2017) were enrolled during one year (July 2017 to June 2018). These children were assessed for the following outcomes: neurological (Hughes disability score, Pediatric Cerebral Performance Category [PCPC], Pediatric Overall Performance Category [POPC], and Glasgow Outcome Scale-Extended Pediatric version [GOS-E Peds] scales), behavioral (Childhood Psychopathology Measurement Schedule [CPMS]), functional (Vineland Social Maturity Scale [VSMS]-Indian Adaptation), quality of life (Pediatric Quality of Life [PedsQL]), and school performance (Parent-Directed Questionnaire)., Results: Eighty children were enrolled after a median of 3.0 (1.3-4.2) years from discharge. The majority (95%) had favorable neurological recovery (Hughes disability score 0 to 1). Favorable outcome was noted in 95% of children on PCPC, 87.5% on POPC, 60% on GOS-E Peds, 86.2% on CPMS, 92.5% on VSMS, and 98% on PedsQL. The majority (97.5%) of childre were attending schools, and 57.7% had satisfactory school performance. The presence of quadriparesis at admission, mechanical ventilation, tracheostomy requirement, poor ambulatory status at discharge, and longer pediatric intensive care unit and hospital stay predicted unfavorable neurological outcome on different tools. Absence of quadriparesis at admission and no requirement of mechanical ventilation predicted a favorable result on all outcome measures., Conclusions: On long-term follow-up, most children with severe GBS showed favorable neurological, behavioral, functional, and quality of life outcomes. Severe clinical presentation and prolonged intensive care unit stay predict poor long-term outcome., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Objectives: To compare the epidemiological, clinical profile, intensive care needs and outcome of children hospitalized with SARS-CoV-2 infection during the first and second waves of the pandemic., Methods: This was a retrospective study of all children between 1 mo and 14 y, admitted to a dedicated COVID-19 hospital (DCH) during the first (1st June to 31st December 2020) and second waves (1st March to 30th June 2021)., Results: Of 217 children, 104 (48%) and 113 (52%) were admitted during the first and second waves respectively. One hundred fifty-two (70%) had incidentally detected SARS-CoV-2 infection, while 65 (30%) had symptomatic COVID-19. Comorbidities were noted in 137 (63%) children. Fifty-nine (27%) and 66 (30%) children required high-dependency unit (HDU) and ICU care respectively. Severity of infection and ICU needs were similar during both waves. High-flow oxygen (n = 5, 2%), noninvasive ventilation [CPAP (n = 34, 16%) and BiPAP (n = 8, 5%)] and invasive ventilation (n = 45, 21%) were respiratory support therapies needed. NIV use was more during the second wave (26% vs. 13%; p = 0.02). The median (IQR) length (days) of DCH stay among survivors was longer during the first wave [8 (6-10) vs. 5.5 (3-8); p = 0.0001]., Conclusions: Disease severity, associated comorbidities, PICU and organ support need and mortality were similar in the first and second waves of the pandemic. Children admitted during the second wave were younger, had higher proportion of NIV use and shorter length of COVID-19 hospital stay., (© 2022.

Background: Staphylococcus aureus co-infection is seldom reported in children with severe dengue., Methodology: In this retrospective study, we reported five children with severe dengue and S. aureus co-infection admitted to pediatric intensive care unit (PICU) during July-December 2021., Results: All children had prolonged fever, persistence of bilateral pleural effusion beyond the critical phase, thrombocytopenia and raised inflammatory markers [C-reactive protein (CRP) and procalcitonin]. S. aureus was isolated from pleural fluid (n = 2, 40%), blood (n = 2, 40%) and endotracheal aspirate (n = 1, 20%). Four children (80%) grew methicillin-sensitive S. aureus, while 1 (20%) had methicillin-resistant S. aureus. Two children (40%) had septic thromboemboli in skin, and 1 (20%) had limb cellulitis. One child required anterior thoracotomy, pericardiectomy and bilateral pleural decortication, while all other children required intercostal chest tube drainage. All children required prolonged targeted antibiotics, invasive mechanical ventilation and had prolong stay in PICU and all of them survived., Conclusion: In children with severe dengue, persistence of fever, persistence of pleural effusion beyond critical phase and raised CRP and procalcitonin should raise suspicion of bacterial/S. aureus co-infection., (© The Author(s) [2022].

Aims and Objectives: To study the epidemiology, microbiological profile, and outcome of culture positive sepsis among outborn neonates at a tertiary care teaching hospital in Northern India., Materials and Methods: Neonates ( n  = 406) with blood culture positive sepsis were enrolled prospectively over a period of 1 year (February 2018-January 2019). Demographic details, clinical features, microbiological profile, antibiotic sensitivity pattern, treatment, and outcome were recorded., Results: The mean (±SD) age at presentation was 2.4 (±0.6) days and 2/3rd were males. The mean (±SD) gestation was 35.5 (±3.4) weeks, birth weight was 2215 (±219) g, and 42.4% were preterm. The proportion of neonates with early and late onset sepsis were 69% and 31%, respectively. Predominant isolates were Gram-negative (46.5%), Gram-positive (27.6%) organisms, and yeast (25.9%). Klebsiella pneumoniae (46.5%), Acinetobacter baumannii (17.5%), and Escherichia coli (8%) were common Gram-negative; and coagulase negative Staphylococcus (CONS) (70%), Staphylococcus aureus (13.4%), and Enterococcus (12.5%) were common Gram-positive organisms. Among Gram-negative organisms, the antibiotic sensitivity pattern was ciprofloxacin 45%, cephalosporins 15-40%, aminoglycosides 20-42%, piperacillin-tazobactam 49%, carbapenems 34-51%, tetracyclines 55-70%, doxycycline 55%, chloramphenicol 42%, and colistin 98%; and among Gram-positive organisms were methicillin 30%, clindamycin 52%, vancomycin 100%, teicoplanin 98%, and linezolid 99%. The survival rate was 60.3%. The neonates with Gram-negative sepsis had higher requirement of oxygen, mechanical ventilation, and vasoactive drugs; had more complications; and lower survival (50.3% vs. 72.3%, p = .003) when compared to Gram-positive sepsis., Conclusions: Gram-negative organisms were commonest cause of neonatal sepsis, had low sensitivity to commonly used antibiotics, and associated with poor outcome.

Carbamazepine is commonly used antiseizure medication with a narrow therapeutic range. The data on carbamazepine poisoning in children from India is limited. In this retrospective study, the authors reported 10 children with carbamazepine poisoning admitted to pediatric intensive care unit (PICU) of a tertiary care teaching hospital in North India over a period of 8 y (2013 to 2020). The median age was 5.5 (4.3-6) y and 60% cases were males. All had accidental ingestion and the dose ingested was 96 (80-103) mg/kg. The common clinical features were drowsiness (100%), tachycardia (80%), vomiting (60%), seizures (60%), respiratory failure (60%), and dystonia (50%). At admission, 60% children had coma. The treatment included gastric lavage (70%), single-dose-activated charcoal (60%), multidose-activated charcoal (30%), mechanical ventilation (60%), and dialysis (20%). The duration of PICU and hospital stay was 36 (22-45) h and 48 (48-60) h, respectively. There was no mortality., (© 2022. Dr. K C Chaudhuri Foundation.)

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., (© The Author(s) [2022].

Acute encephalitis is a syndromic diagnosis. In the last two decades, a unique clinico-radiological entity, named acute encephalopathy with biphasic seizures and late restricted diffusion (AESD), has been reported in children from Asia. It is characterised by an acute febrile illness with seizures and encephalopathy, with some initial improvement followed by a second flurry of seizures and deep encephalopathy, 3-4 days later. MRI may show a pattern of 'bright tree appearance'. An aetiological agent may not always be identified but an infectious trigger is proposed. Immunomodulatory therapy has been tried with variable results. The prognosis is variable, and children are usually left with neurological sequelae including epilepsy and cognitive impairment. We describe a female infant who presented with the typical clinico-radiological syndrome of AESD and human bocavirus was identified in the stool. She received steroids and antiepileptic drugs. She has persistent cognitive impairment at follow-up but remained seizure free., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022. No commercial re-use.

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., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2022 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.)

Background: Prospective data on hand hygiene compliance in pediatric emergency department (PED) settings is limited. We studied the impact of quality improvement measures on the overall and health care personnel wise hand hygiene compliance rates in a busy PED., Methods: The baseline hand hygiene compliance rates were audited from May-July 2018. The quality improvement interventions included various structural changes to the environment, administrative changes, education and training. During the interventions, auditing was continued for 2 months (August - September 2018). Statistical Process control charts were created., Results: We observed a significant increase in overall compliance rates from 31.8 to 53.9% ( p < 0.001). These improvements were observed in the children (29.6 to 46.4%, p < 0.001) as well as neonatal area (35.7% to 59.7, p < 0.001) of PED as well as amongst various health care personnel and in four out of the five moments of hand hygiene., Conclusion: Hand hygiene compliance improved significantly in a busy PED of a lower middle-income country following quality improvement interventions. Such improvement was observed amongst all categories of health care personnel and different types of hand hygiene opportunities. This study demonstrates the feasibility and efficacy of simple quality improvement interventions in a challenging hospital environment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Angurana, Chetal, Mehta, Suthar, Sundaram, Singh, Kaur, Kaur, Biswal, Kumar and Jayashree.)
