RESUMO
OBJECTIVES: To compare high-flow nasal cannula (HFNC) versus nasal prong bubble continuous positive airway pressure (b-CPAP) in children with moderate to severe acute bronchiolitis. DESIGN: A randomized controlled trial was carried out from August 2019 to February 2022. (Clinical Trials Registry of India number CTRI/2019/07/020402). SETTING: Pediatric emergency ward and ICU within a tertiary care center in India. PATIENTS: Children 1-23 months old with moderate to severe acute bronchiolitis. INTERVENTION: Comparison of HFNC with b-CPAP, using a primary outcome of treatment failure within 24 hours of randomization, as defined by any of: 1) a 1-point increase in modified Wood's clinical asthma score (m-WCAS) above baseline, 2) a rise in respiratory rate (RR) greater than 10 per minute from baseline, and 3) escalation in respiratory support. The secondary outcomes were success rate after crossover, if any, need for mechanical ventilation (invasive/noninvasive), local skin lesions, length of hospital stay, and complications. RESULTS: In 118 children analyzed by intention-to-treat, HFNC ( n = 59) versus b-CPAP ( n = 59) was associated with a lower failure rate (23.7% vs. 42.4%; relative risk [95% CI], RR 0.56 [95% CI, 0.32-0.97], p = 0.031). The Cox proportion model confirmed a lower hazard of treatment failure in the HFNC group (adjusted hazard ratio 0.48 [95% CI, 0.25-0.94], p = 0.032). No crossover was noted. A lower proportion escalated to noninvasive ventilation in the HFNC group (15.3%) versus the b-CPAP group (15.3% vs. 39% [RR 0.39 (95% CI, 0.20-0.77)], p = 0.004). The HFNC group had a longer median (interquartile range) duration of oxygen therapy (4 [3-6] vs. 3 [3-5] d; p = 0.012) and hospital stay (6 [5-8.5] vs. 5 [4-7] d, p = 0.021). No significant difference was noted in other secondary outcomes. CONCLUSION: In children aged one to 23 months with moderate to severe acute bronchiolitis, the use of HFNC therapy as opposed to b-CPAP for early respiratory support is associated with a lower failure rate and, secondarily, a lower risk of escalation to mechanical ventilation.

OBJECTIVE: To determine if initial fluid resuscitation with balanced crystalloid (e.g., multiple electrolytes solution [MES]) or 0.9% saline adversely affects kidney function in children with septic shock. DESIGN: Parallel-group, blinded multicenter trial. SETTING: PICUs of four tertiary care centers in India from 2017 to 2020. PATIENTS: Children up to 15 years of age with septic shock. METHODS: Children were randomized to receive fluid boluses of either MES (PlasmaLyte A) or 0.9% saline at the time of identification of shock. All children were managed as per standard protocols and monitored until discharge/death. The primary outcome was new and/or progressive acute kidney injury (AKI), at any time within the first 7 days of fluid resuscitation. Key secondary outcomes included hyperchloremia, any adverse event (AE), at 24, 48, and 72 hours, and all-cause ICU mortality. INTERVENTIONS: MES solution ( n = 351) versus 0.9% saline ( n = 357) for bolus fluid resuscitation during the first 7 days. MEASUREMENTS AND MAIN RESULTS: The median age was 5 years (interquartile range, 1.3-9); 302 (43%) were girls. The relative risk (RR) for meeting the criteria for new and/or progressive AKI was 0.62 (95% CI, 0.49-0.80; p < 0.001), favoring the MES (21%) versus the saline (33%) group. The proportions of children with hyperchloremia were lower in the MES versus the saline group at 24, 48, and 72 hours. There was no difference in the ICU mortality (33% in the MES vs 34% in the saline group). There was no difference with regard to infusion-related AEs such as fever, thrombophlebitis, or fluid overload between the groups. CONCLUSIONS: Among children presenting with septic shock, fluid resuscitation with MES (balanced crystalloid) as compared with 0.9% saline resulted in a significantly lower incidence of new and/or progressive AKI during the first 7 days of hospitalization.

BACKGROUND: Studies comparing the modified Schwartz formula with measured GFR (m-GFR) are lacking in critically ill children. METHODS: This prospective cohort study enrolled children aged 1 month to 12 years, within 24 h of admission. m-GFR measured by technetium-99m-labeled diethylenetriaminepentaacetic acid (99mTc-DTPA) and calculated by Russell's two-sample slope-intercept method. Serum creatinine was estimated by modified Jaffe method and estimated GFR (e-GFR) calculated by modified Schwartz formula. The primary outcome was to find agreement between the two methods. Bias, precision, and accuracy were calculated. Secondary outcomes were the incidence of AKI (by p-RIFLE criteria) and the difference between the two methods to diagnose AKI. RESULTS: A total of 208 pairs were analyzed. e-GFR showed good agreement with m-GFR with a mean bias of -4.37 ml/min/1.73 m2 and precision (SD of bias) of 33.07, 95% limit of agreement -69.18 to 60.45, and intraclass correlation of 74% (95%CI 66-80%, P < 0.001). e-GFR underestimated m-GFR by 19.8% (95% CI 7.9-31.7%). Accuracy of e-GFR values within 10%, 20%, and 30% of m-GFR were 68.3%, 72.6%, and 78.8%, respectively. Incidence of AKI within 24 h was 60.1% by e-GFR and 54.3% by m-GFR (kappa 0.569, P < 0.001; sensitivity of 85.8%, 95%CI (78-91.7%). CONCLUSIONS: The modified Schwartz formula shows good agreement with 99mTc-labeled DTPA double plasma sample clearance method for calculating GFR in critically ill children aged 1 month to 12 years. The underestimation of GFR should be kept in mind while applying the formula at the bedside in PICU.

Introduction: The chest X-ray (CXR) is the standard of practice to assess the tip of the endotracheal tube (ETT) in ventilated children. In many hospitals, it takes hours to get a bedside CXR, and it has radiation exposure. The objective of this study was to find the utility of bedside ultrasound (USG), in assessing the ETT tip position in a Pediatric Intensive Care Unit (PICU). Methods: It was a prospective study conducted in the PICU of a tertiary care center involving 135 children aged from 1 month to 60 months, requiring endotracheal intubation. In this study, the authors compared the position of the ETT tip by the CXR (gold standard) and USG. The CXR was taken in children to assess the correct position of the tip of ETT. The USG was used to measure the distance between the tip of ETT and the arch of the aorta, thrice in the same patient. The mean of the three USG readings was compared with the distance between the tip of the ETT and carina in CXR. Results: The reliability of three USG readings was tested by absolute agreement coefficient in intraclass correlation (ICC), 0.986 (95% CI: 0.981-0.989). The sensitivity and specificity of the USG in identifying the correct position of the ETT tip in children when compared to CXR were 98.10% (95% CI: 93.297-99.71%) and 50.0% (95% CI: 31.30-68.70%), respectively. Conclusion: In ventilated children <60 months of age, identifying the tip of ETTs by bedside the USG has good sensitivity (98.10%) but poor specificity (50.0%).

RESUMO
OBJECTIVES: To examine if the use of honey (medicated) for dressing is superior to standard care in terms of time to complete wound healing in stages 1-3 of pressure injuries in children admitted to the PICU. DESIGN: Multicenter, open-label, parallel-group, randomized trial. SETTING: Tertiary-care PICU from August 2017 to January 2019. PATIENTS: Critically ill children, 2 months to 17 years old, who developed pressure injury (stages 1-3) were included; those on more than two inotropes or with signs of acute wound infection or wounds with greater than 5 cm diameter or known allergy to honey were excluded. INTERVENTIONS: Children were randomized to receive either medicated honey dressing or standard (routine) wound care for the management of their pressure injury. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the time to complete wound healing. Manuka or active Leptospermum honey dressing/gel was used in the intervention group. Enrolled children were followed up until death or discharge from the hospital. A total of 99 children were enrolled: 51 in the intervention group and 48 in the standard care group. Baseline characteristics, including the nutritional status, were comparable between the groups. The most common sites of injury were bony prominences at face mask contact points. The median time to complete healing was 7 days (95% CI, 6-7 d) versus 9 days (7-10 d) in the intervention and standard care groups, respectively (p = 0.002; log-rank test). At any random time, children in the intervention group were about 1.9-fold more likely to have their pressure injury completely healed than those in the standard care group (hazard ratio 1.86; 95% CI, 1.21-2.87). There were no allergic reactions or secondary wound infections in the intervention group. CONCLUSIONS: The use of medicated honey dressings decreased the time to wound healing in critically ill children with pressure injuries. There were no allergic reactions or secondary bacterial infections in any of these children.

BACKGROUND AND OBJECTIVES: Among Southeast Asian countries, India has reported the highest mortality due to snakebite envenomation. To identify the risk factors of poor outcome (mortality/mechanical ventilation/renal replacement therapy-RRT) in pediatric snakebite envenomation. METHOD: Case records of children aged less than 13 years with snakebite envenomation admitted between June 2009 and July 2015 were reviewed retrospectively. Medical records of the patient died within 6 h, those required RRT before administration of antisnake venom (ASV), and those with unknown bites were excluded. RESULTS: A total of 308 patients were included. One hundred eighty (58.4%) had hemotoxic, and 128 (41.6%) had neuroparalytic envenomation. Median (interquartile range) bite to ASV time was 3 (2-6) h. Seventy-five (24.4%) patients received ASV within 6 h of bite. Poor outcomes occurred in 128 (41.6%), and 36 (11.7%) patients died. On binary logistic analysis (adjusted odds ratio, 95% confidence interval), age ≤5 years (2.97, 1.28-6.90), walking (6.15, 2.88-13.17), playing (3.36, 1.64-6.88), no tourniquet (2.39, 1.25-4.57), time to ASV more than 6 h (2.71, 1.45-5.06), fang marks (2.22, 1.21-4.07), neurotoxic envenomation (3.01, 1.11-8.13) and additional ASV dose (8.41, 2.99-23.60) were independently predicted the poor outcome (Hosmer and Lemeshow goodness of fit model p = 0.135; overall percentage of the model is 72.2% and R-square = 0.28). CONCLUSION: Age below 5 years, activity at/after the bite (playing/walking), no tourniquet, a longer bite to ASV time, presence of fang marks, neurotoxic envenomation and need for additional ASV dose were independent predictors of poor outcome in pediatric snakebite envenomation.

OBJECTIVE: Rapid advancements in medicine and changing standards in medical education require new, efficient educational strategies. We investigated whether an online intervention could increase residents' knowledge and improve knowledge retention in mechanical ventilation when compared with a clinical rotation and whether the timing of intervention had an impact on overall knowledge gains. DESIGN: A prospective, interventional crossover study conducted from October 2015 to December 2017. SETTING: Multicenter study conducted in 33 PICUs across eight countries. SUBJECTS: Pediatric categorical residents rotating through the PICU for the first time. We allocated 483 residents into two arms based on rotation date to use an online intervention either before or after the clinical rotation. INTERVENTIONS: Residents completed an online virtual mechanical ventilation simulator either before or after a 1-month clinical rotation with a 2-month period between interventions. MEASUREMENTS AND MAIN RESULTS: Performance on case-based, multiple-choice question tests before and after each intervention was used to quantify knowledge gains and knowledge retention. Initial knowledge gains in residents who completed the online intervention (average knowledge gain, 6.9%; SD, 18.2) were noninferior compared with those who completed 1 month of a clinical rotation (average knowledge gain, 6.1%; SD, 18.9; difference, 0.8%; 95% CI, -5.05 to 6.47; p = 0.81). Knowledge retention was greater following completion of the online intervention when compared with the clinical rotation when controlling for time (difference, 7.6%; 95% CI, 0.7-14.5; p = 0.03). When the online intervention was sequenced before (average knowledge gain, 14.6%; SD, 15.4) rather than after (average knowledge gain, 7.0%; SD, 19.1) the clinical rotation, residents had superior overall knowledge acquisition (difference, 7.6%; 95% CI, 2.01-12.97;p = 0.008). CONCLUSIONS: Incorporating an interactive online educational intervention prior to a clinical rotation may offer a strategy to prime learners for the upcoming rotation, augmenting clinical learning in graduate medical education.

OBJECTIVES: Mannitol is a commonly used osmotherapy agent in raised intracranial pressure. However, the side effects of mannitol are significant. In traumatic brain injury (adult and pediatric), hypertonic saline (3%) shows varied results in comparison with 20% mannitol. We compared the effect of 3% hypertonic saline versus 20% mannitol (using common dosing strategies) on raised intracranial pressure in pediatric acute CNS infections. DESIGN: Open-label randomized controlled trial. SETTING: PICU of a quaternary care academic institute. PATIENTS: Children 1-12 years old, with raised intracranial pressure and modified-Glasgow Coma Scale scores less than or equal to 8, were enrolled. INTERVENTIONS: Patients were randomly assigned to 20%-mannitol (n = 28), 0.5 gram/kg/dose versus 3%-hypertonic saline (n = 29), 10 mL/kg loading followed by 0.5-1 mL/kg/hr infusion. An intraparenchymal catheter was used to monitor the intracranial pressure. The primary outcome was the proportion of patients achieved target average intracranial pressure less than 20 mm Hg during 72 hours. Secondary outcomes were interventions, morbidity, and mortality. MEASUREMENTS AND MAIN RESULTS: The proportion of patients with target average intracranial pressure (< 20 mm Hg) was higher in hypertonic saline-group as compared to mannitol-group (79.3% vs 53.6%; adjusted hazard ratio 2.63; 95% CI: 1.23-5.61). Mean (± SE) reduction of intracranial pressure (-14.3 ± 1.7 vs -5.4 ± 1.7 mm Hg; p ≤ 0.001) and elevation of cerebral perfusion pressure (15.4 ± 2.4 vs 6 ± 2.4 mm Hg; p = 0.007) from baseline were significant in hypertonic saline-group. Mean (± SE) intracranial pressure over 72 hours was lower (14 ± 2 vs 22 ± 2 mm Hg; p = 0.009), and cerebral perfusion pressure was higher (65 ± 2.2 vs 58 ± 2.2; p = 0.032) in hypertonic saline-group. Hypertonic saline-group had higher modified-Glasgow Coma Scale score at 72 hours (median, interquartile range 10; 7-11 vs 7; 3-9; p = 0.003), lower mortality (20.7% vs 35.7%; p = 0.21), shorter duration of mechanical ventilation (5 vs 15 d; p = 0.002), and PICU stay (11 vs 19 d; p = 0.016) and less severe neurodisability at discharge (31% vs 61%; p = 0.049). CONCLUSIONS: In pediatric acute CNS infections, 3%-hypertonic saline was associated with a greater reduction of intracranial pressure as compared to 20% mannitol.

OBJECTIVE: The aim of this study was to compare the effectiveness of Ringer lactate (RL) versus normal saline (NS) in the correction of pediatric acute severe diarrheal dehydration, as measured by improvement in clinical status and pH (≥7.35). METHODS: A total of 68 children ages 1 month to 12 years with acute severe diarrheal dehydration (World Health Organization [WHO] classification) were randomized into RL (nâ=â34) and NS groups (nâ=â34) and received 100âmL/kg of the assigned intravenous fluid according to WHO PLAN-C for the management of diarrheal dehydration. The primary outcome was an improvement in clinical status and pH (≥7.35) at the end of 6 hours. Secondary outcomes were changes in serum electrolytes, renal and blood gas parameters, the volume of fluid required for dehydration correction excluding the first cycle, time to start oral feeding, hospital stay, and cost-effectiveness analysis. RESULTS: Primary outcome was achieved in 38% versus 23% (relative riskâ=â1.63, 95% confidence interval 0.80-3.40) in RL and NS groups, respectively. No significant differences were observed in secondary outcomes in electrolytes, renal, and blood gas parameters. None required second cycle of dehydration correction. Median (interquartile range) time to start oral feeding (1.0 [0.19-2.0] vs 1.5 [0.5-2.0] hours) and hospital stay (2.0 [1.0-2.0] vs 2.0 [2.0-2.0] days) was similar. The median total cost was higher in RL than NS group ((Equation is included in full-text article.)120 [(Equation is included in full-text article.)120-(Equation is included in full-text article.)180] vs (Equation is included in full-text article.)55 [(Equation is included in full-text article.)55-(Equation is included in full-text article.)82], Pâ≤â0.001). CONCLUSION: In pediatric acute severe diarrheal dehydration, resuscitation with RL and NS was associated with similar clinical improvement and biochemical resolution. Hence, NS is to be considered as the fluid of choice because of the clinical improvement, cost, and availability.

BACKGROUND: Septic acute kidney injury (AKI) accounts for more than half of all cases of AKI in critically ill children. The renal histology was found to alter the management in more than two-third of cases of adult acute renal failure. Better insight into the pathogenesis of pediatric septic AKI could be based on developing a clearer appreciation of the histopathological changes. No comprehensive study of the histopathological features of septic AKI in critically ill children has yet been performed. METHODS: This retrospective observational study was conducted at a level-III pediatric intensive care unit (PICU) from June 2013 to July 2014. Children (<13 years of age) who had expired due to sepsis and AKI and had post-mortem renal biopsies were included. Sepsis and AKI were defined according to the International pediatric sepsis consensus conference and Acute Kidney Injury Network (AKIN) definition and classification system, respectively. RESULTS: A total of 708 patients were admitted to the PICU during the study period, with mortality of 24 % (n = 170) and 62 complete data of post-mortem renal biopsies were included. The median (IQR) age was 12 (4.8-36) months, pediatric risk of mortality score (PRISM) III was 14 (12-18) and the time to biopsy after death was 24 (18-26) minutes. Normal histology was the most common change 41.9 % (n = 26), followed by acute tubular necrosis (ATN) 30.6 % (n = 19). A combination of changes involving tubules, glomeruli, interstitium, and blood vessels was noted in 21 % (n = 13) of the specimens. Eight percent (n = 5) of the specimens had features consistent with thrombotic microangiopathy. Normal histology was noted in 15.4 % (n = 4/26), 50 % (n = 13/26), and 34.6 % (n = 9/26) of AKI stage-I, II, and III, respectively. CONCLUSION: The most common renal histopathological change in septic AKI in critically ill children was normal histology followed by ATN.

Cleistanthus collinus, also known as Oduvanthalai in Tamil, is the most commonly encountered plant poison in southern India. The leaves are used for poisoning humans (suicide or homicide) and animals (cattle and fish) and as an abortifacient, especially in rural south India. Although this poisoning is commonly reported in adults, data regarding the use of N-acetylcysteine in pediatric poisoning is lacking. We report two previously healthy male siblings of pediatric age group who ingested the liquid extracted from crushed leaves of this plant given to them by their mother as a means of deliberate harm. Both patients developed distal renal tubular acidosis, with hypokalemia. The younger sibling also developed myocardial toxicity. Other significant findings noted include hypocalcemia, hypomagnesemia and elevated liver enzymes. Both patients received supportive care along with N-acetylcysteine infusion, and showed complete recovery within 10 days.

Objective: To compare the effectiveness of early high-flow nasal cannula (HFNC) and low-flow oxygen support (LFOS) in children under 5 years with acute hypoxemic respiratory failure (AHRF) due to severe community-acquired pneumonia in low-middle-income countries. Methods: An open-label randomized clinical trial enrolled children aged 2-59 months with AHRF due to severe community-acquired pneumonia and randomized into HFNC and LFOS. In the LFOS group, the patient received cold wall oxygen humidified by bubbling through sterile water administered through simple nasal prongs at a fixed flow rate of 2 L/min. In the HFNC group, the patient received humidified, heated (37 °C), high-flow oxygen at a flow rate assigned based on weight range, with a titratable oxygen fraction. The primary outcome was treatment failure in 72 h (escalating the respiratory support method using any modality other than primary intervention). Results: Data was analyzed intention-to-treat (HFNC = 124; LFOS = 120). Median (IQR) age was 12 (6-20) and 11 (6-27) months, respectively. Treatment failure occurred in a significantly lower proportion in the HFNC group (7.3%, n = 9/124) as compared to the LFOS group (20%, n = 24/120) (relative risk = 0.36, 95% CI 0.18 to 0.75; p = 0.004; adjusted hazard ratio 0.34, 95% CI 0.16 to 0.73; p = 0.006). The intubation rate was significantly lower in the HFNC group (7.3%, n = 9/124 vs. 16.7%, n = 20/120; relative risk = 0.44, 95% CI 0.21 to 0.92, p = 0.023). There were no significant differences noted in other secondary outcomes. No mortality occurred. Conclusion: High-flow nasal cannula oxygen therapy used as early respiratory support in children under 5 years with acute hypoxemic respiratory failure due to severe community-acquired pneumonia was associated with significantly lower treatment failure compared with standard low-flow oxygen support.

OBJECTIVE: To study the association of cumulative fluid balance and clinical outcomes in a pediatric intensive care unit (PICU) practicing restrictive fluid protocol. METHODS: In this prospective cohort study, children aged less than 13 y admitted for more than 48 h were screened. Children with unstable hemodynamics throughout the stay were excluded. Fluid balance was calculated by percentage fluid overload (%FO) for the first 7 d. Patients were divided into positive fluid and negative fluid balance groups. The primary outcome was all-cause 28-d mortality. RESULTS: A total of 888 patients (positive fluid balance group = 531, negative fluid balance group = 357) were analyzed. Mean (SD) cumulative %FO was 1.52 (0.67) vs. -1.18 (0.71), p = < 0.001, and minimum and maximum cumulative %FO were -3.0% and 3.1%, respectively. There was no significant difference in all-cause 28-d mortality between the two groups (n = 104/531, 19.6% vs. n = 60/357, 16.8%, RR = 1.17, 95% CI 0.87 to 1.55; p = 0.29). There was no difference in organ dysfunction [mean (SD) sequential organ failure assessment (SOFA) score 3.3 (0.7) vs. 3.3 (0.6)], acute kidney injury (65% vs. 63.6%), need for renal replacement therapy (14% vs. 13%), and duration of ventilation (median, IQR 4, 2-6 vs. 4, 2-6 d). Longer stay in PICU (5, 3-9 vs. 4, 3-7 d; p = 0.014) and in hospital (8, 5-11 vs. 7, 4-10 d; p = 0.007) were noted in the positive fluid balance group. CONCLUSION: Cumulative fluid balance within 3% using restrictive fluid protocol was not associated with a significant difference in PICU mortality and morbidity.

OBJECTIVE: To determine the threshold of the inotropic score (IS) and vasoactive-inotropic score (VIS) for predicting mortality in pediatric septic shock. METHOD: This retrospective cohort study included children aged 1 mo to 13 y with septic shock, requiring vasoactive medication. The area under curve receiver operating characteristic (AUROC) was calculated using mean IS and mean VIS to predict PICU mortality, and Youden index cut points were generated. Sensitivity, specificity, and binary regression analysis were performed. RESULTS: A total of 176 patients were enrolled (survivor, n = 72, 41% and nonsurvivor, n = 104, 59%). For predicting the PICU mortality, AUROC (95% CI) of IS was 0.80 (0.74-0.86) [sensitivity of 88.5 (80.7-94) and specificity of 58.3 (46.1-69.8)] and AUROC of VIS was 0.88 (0.82-0.92) [sensitivity of 83.7 (75.1-90.2) and specificity of 80.6 (69.5-89)]. The respective cutoff scores of IS and VIS were 28 and 42.5. On regression analysis (adjusted odds ratio, 95% CI), illness severity (PRISM-III) (1.12, 1.05-1.12), worst lactate value (1.31, 1.08-1.58), IS (> 28) (3.98, 1.24-12.80), and VIS (> 42.5) (4.66, 1.57-13.87) independently predicted the PICU mortality (r2 = 0.625). CONCLUSION: Threshold of inotropic score (> 28) and vasoactive-inotropic score (> 42.5) were independently associated with PICU mortality. In addition to IS and VIS, severity and worst lactate value independently predicted septic shock mortality in PICU.

OBJECTIVE: To compare early goal-directed therapy (EGDT) 'with' and 'without' intermittent superior vena cava oxygen saturation (ScvO2) monitoring in pediatric septic shock. DESIGN: Open label randomized controlled trial. SETTING: Pediatric intensive care unit in a tertiary care center. PARTICIPANTS: Children aged 1 month to 12 year with septic shock. INTERVENTION: Patients not responding to fluid resuscitation (up to 40 mL/kg) were randomized to EGDT 'with' (n=59) and 'without' (n=61) ScvO2 groups. Resuscitation was guided by ScvO2 monitoring at 1-hour, 3-hour, and later on six-hourly in the 'with' ScvO2 group, and by clinical variables in the 'without' ScvO2 group. OUTCOME: Primary outcome was all-cause 28-day mortality. Secondary outcomes were time to and proportion of patients achieving therapeutic endpoints (at 6 hours and PICU stay), need for organ supports, new organ dysfunction (at 24 hours and PICU stay), and length of PICU and hospital stay. RESULTS: The study was stopped after interim analysis due to lower mortality in the intervention group. There was significantly lower all-cause 28-day mortality in EDGT with ScvO2 than without ScvO2 group [37.3% vs. 57.5%, adjusted hazard ratio 0.57, 95%CI 0.33 to 0.97, P=0.04]. Therapeutic endpoints were achieved early in 'with' ScvO2 group [mean (SD) 3.6 (1.6) vs. 4.2 (1.6) h, P=0.03]. Organ dysfunction by sequential organ assessment score during PICU stay was lower in 'with' ScvO2 group [median (IQR) 5 (2,11) vs. 8 (3,13); P=0.03]. There was no significant difference in other secondary outcomes. CONCLUSIONS: EGDT with intermittent ScvO2 monitoring was associated with reduced mortality and improved organ dysfunction in pediatric septic shock.

OBJECTIVE: To study the serum sodium level and clinical outcome in pediatric nontraumatic coma. METHODS: A prospective cohort study was conducted in a tertiary care pediatric intensive care unit (PICU) from September 2015 to June 2016. Children aged < 13 y with nontraumatic coma [modified-Glasgow Coma Scale (m-GCS) score ≤ 8 or fall of ≥ 3 from baseline within 24 h of admission] were included. Children who received intravenous fluids for > 24 h, those with developmental delay, or died within 24 h of admission were excluded. The serum sodium profile (mEq/L) in the first 72 h and clinical outcome [mortality, length of stay in mechanical ventilation, PICU, and hospital] were studied. RESULTS: Eighty patients [Died n = 26 and Survived n = 54] were enrolled. Median [interquartile range (IQR)] age and m-GCS were 21 (4-78) mo and 9 (7-11), respectively. The mean [standard deviation (SD)] Pediatric Risk of Mortality-III (PRISM-III) was 17.7 (4). The most common etiology was acute central nervous system (CNS) infections (30%, n = 24) followed by an intracranial bleed (11.3%, n = 9). Mean (Standard error, SE) sodium levels and fluctuation of serum sodium from baseline up to 72 h were similar between nonsurvivors and survivors [140.8 (1.3) vs. 139.6 (0.8), p = 0.421] and [1.2 (0.3) vs. 0.8 (0.2), p = 0.307], respectively. On multivariate analysis, the need for vasoactive therapy was an independent predictor of mortality [adjusted odds ratio = 20.78, 95% CI 4.24-101.85, p = < 0.001, R2 = 0.62]. CONCLUSION: Mean serum sodium within normal range and fluctuation of serum sodium of 0.8 to 1.2 mEq/L over 72 h was not associated with poor outcomes in pediatric nontraumatic coma. Vasoactive therapy was an independent predictor of mortality.

OBJECTIVE: To study the clinical outcomes of red blood cell (RBC) transfusion practices in critically ill children. METHOD: This prospective cohort study was conducted in a tertiary care pediatric intensive care unit (PICU) from March-2015 to January-2018. Inverse probability of treatment weighting (IPTW) using propensity score analysis was used. Children aged 1 mo to 12 y admitted to the PICU were screened. Patients were classified into 'transfused' and 'nontransfused', based on whether they received a transfusion or not. Patients with hematological malignancies, or immunosuppressant drugs, or those who received repeated transfusions, or received transfusion before admission, or died within 24 h were excluded. The primary outcome was all-cause 28 d mortality. Secondary outcomes were new-onset organ dysfunction, mechanical ventilation duration, and length of PICU and hospital stay. RESULTS: A total of 1014 patients [transfused = 277; nontransfused = 737) were included. In IPTW analysis, the risk of all-cause 28 d mortality was 53% higher in transfused than nontransfused patients [hazard ratio = 1.53, 95% CI: 1.18-1.98, p = 0.001 by Log-rank test]. Organ dysfunction was higher in transfused than nontransfused patients [3.8% vs. 1.3%, hazard ratio = 3.0, 95% CI: 1.40-6.48, p = 0.005]. The risk of staying in the mechanical ventilation was similar in both groups [hazard ratio = 1.03, 95% CI: 0.86-1.23, p = 0.756]. The risk of extended stay in the PICU and hospital was 16% and 21% higher in transfused than nontransfused patients [hazard ratio = 1.16, 95% CI: 1.03-1.30; p = 0.005; and 1.21, 95% CI: 1.08-1.36; p = 0.001], respectively. CONCLUSION: Red blood cell transfusion was independently associated with higher all-cause 28 d mortality and morbidities in critically ill children.

OBJECTIVES: To study the incidence of contrast-induced acute kidney injury (CI-AKI), evaluate its risk factors, study the role of plasma neutrophil gelatinase-associated lipocalin (NGAL) and evaluate the outcome of CI-AKI in critically ill children. METHODS: In this prospective cohort study, children aged 1 mo to 12 y who underwent contrast computed tomography (CECT) for various medical indications were included. Patients without renal function test before contrast administration, children with chronic kidney disease, children admitted for less than 48 h, and those with serum bilirubin more than 5 mg per dL were excluded. Serum creatinine and estimated-Glomerular filtration rate (e-GFR) were measured at admission, immediately before, and at 6, 24, 48 h after contrast. Plasma neutrophil gelatinase-associated lipocalin (NGAL) was measured before and 6 h after contrast. The incidence of CI-AKI by p-RIFLE (Pediatric Risk, Injury, Failure, Loss, End Stage Renal Disease) criteria, its risk factors, the diagnostic role of NGAL in CI-AKI, and outcomes [30 d unfavorable outcome (death, readmission) and renal recovery] were studied. RESULTS: One hundred children were enrolled. The indications for CECT were brain (58%) and respiratory pathology (20%). Incidence of CI-AKI was 35% (95% CI 26.4% to 44.8%); 71% in 'Risk,' and 29% in the 'Injury' stage. After multivariate logistic regression, age younger than 2 y was independently associated with CI-AKI. There was no significant difference in NGAL before (ROC-AUC 0.38, 95% CI 0.26 to 0.50) and 6 h after CECT scan (AUC 0.41, 95% CI 0.29 to 0.54) to predict CI-AKI. There were 7% deaths but no readmission at 30 d. Among 33 CI-AKI patients who survived, the operational definition of renal recovery was achieved in 51.5% (n = 17), complete renal recovery was achieved in 97% (n = 32), and partial renal recovery was achieved in 3% (n = 1) of patients at discharge, while none received renal supportive therapy. CONCLUSIONS: The incidence of contrast-induced acute kidney injury was 35% with age younger than two year being independently associated with CI-AKI. NGAL did not predict the CI-AKI.
