ABSTRACT
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.
ABSTRACT
Aim: Survey of treatment practices and adherence to pediatric status epilepticus (PSE) management guidelines in India. Methods: This eSurvey was conducted over 35 days (15th October to 20th November 2023) and included questions related to hospital setting; antiseizure medications (ASMs); ancillary treatment; facilities available; etiology; and adherence to PSE management guidelines. Results: A total of 170 respondents participated, majority of them were working in tertiary level hospitals (94.1%) as pediatric intensivists (56.5%) and pediatricians (19.4%), and were in clinical practice for 2-10 years (46.5%). Majority use intravenous (IV) midazolam and levetiracetam as first- and second-line ASMs (67.1 and 51.2%, respectively). In cases with refractory status epilepticus (RSE), the most commonly used ASM is midazolam infusion (92.4%). For super-refractory status epilepticus (SRSE), the commonly used third-line ASMs include midazolam infusion (34.1%), thiopentone infusion (26.5%), high dose phenobarbitone (18.2%), and ketamine infusion (15.3%). Overall, in cases with SRSE, 44.7% respondents use ketamine infusion, 42.5% use add-on oral topiramate, and 34.7% use high-dose phenobarbitone (1-3 mg/kg/hour) infusion. Most respondents targeted both clinical and EEG seizure control (48.8%). Ancillary treatment used for SRSE included IV pyridoxine (57.1%), methylprednisolone (45.3%), IVIG (42.4%), ketogenic diet (40.6%), and second-line immunomodulation (33.5%). Most common causes were febrile SE, viral encephalitis, and febrile illness-related epilepsy syndrome (60.6%, 52.4%, and 37.1%, respectively). Facilities available included pediatric intensive care units (PICU) (97.1%), mechanical ventilation (98.2%), pediatric neurologist (68.8%), MRI brain (86.5%), EEG (69.4%), and viral PCR (58.2%). The compliance with guidelines for timing of initiation of ASM ranged from 63.5 to 88.8%. Conclusion: Intravenous midazolam bolus/es, levetiracetam, and midazolam infusion are commonly used first-, second-, and third-line ASMs, respectively. There were wide variations in use of ASMs for RSE and SRSE, ancillary treatment, and compliance to PSE management guidelines.

ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
OBJECTIVES: To evaluate the assortment of tracheobronchial abnormalities on computed tomography angiography (CTA) in children with congenital heart disease (CHD). METHODS: In this study approved by the Institute ethics committee, CTA studies of 182 children (age range: 2 days-8 years) with CHD, performed from July 2021 to March 2023 were analyzed. Two pediatric radiologists independently assessed the tracheobronchial airways (from the trachea to lobar bronchi) for developmental and branching anomalies and airway compromise (narrowing). In cases which demonstrated airway compromise, the extent and the cause of airway narrowing were evaluated, and the etiology were divided into extrinsic and intrinsic causes. Interobserver agreement between the two radiologists was calculated using kappa statistics. RESULTS: One hundred children demonstrated normal airway anatomy and no luminal narrowing. Airway narrowing was observed in 63 (34.6%) children (κ: 0.954), and developmental airway anomalies were seen in 32 (17.5%) children (κ: 0.935). Of the 63 children with airway narrowing, 47 (25.8%) children had extrinsic cause for narrowing, 11 (6%) children had intrinsic causes for narrowing, and 5 (2.7%) children had both intrinsic and extrinsic causes attributing to airway compromise. Significant airway narrowing (>50% reduction) was seen in 35 (19.2%) children (κ: 0.945). CONCLUSION: Tracheobronchial airway abnormalities are frequently associated in children with CHD and need to be appraised preoperatively. Cross-sectional imaging with CTA provides excellent information on tracheobronchial airway anatomy and caliber as well as delineates the possible etiology of airway narrowing, thus accurately diagnosing airway anomalies.

BACKGROUND: Fever in children is one of the most common reasons for outpatient visits as well as in-patient evaluation, often causing anxiety among parents and caregivers. Fever can be a standalone feature or be associated with other localising symptoms and signs like rash, lymphadenopathy, or any other organ system involvement with or without a focus of infection. The etiologies of fever vary depending on the clinical setting and epidemiology. India being a tropical country, sees a distinct spectrum of tropical infections. Physicians need to stay updated on the prevalent diseases in their region and the unique factors that may influence the clinical presentations and course of fever in the cohort of children they manage. The challenge lies in balancing the benefit of early treatment for severe diseases versus the harms of unnecessary investigations and treatment for self-resolving illnesses. OBJECTIVES: This review aims to provide a comprehensive overview of fever in children, covering its etiology, clinical features, and management strategies. This review offers an algorithmic approach to fever tailored to the Indian setting to guide physicians in identifying the disease based on clinical symptoms and signs, ordering essential laboratory investigations, and initiating appropriate management promptly. CONTENT: The review categorises fever into various segments like fever with localising signs like rash, lymphadenopathy, fever due to infection localised to a particular organ system, and fever without a focus including fever of unknown origin. It delves into the diverse etiological factors contributing to fever in each of these categories, encompassing infectious and non-infectious origins. It gives pointers to identify the etiology from history, examination, and confirm them with judicious use of diagnostic investigations with emphasis on identifying the red flag signs that require immediate attention, especially in vulnerable groups like neonates and young infants.
