Abstract
OBJECTIVES To evaluate management changes and outcomes in critically ill children after formal echocardiography. DESIGN Retrospective cohort study between January 1, 2011, and December 31, 2020. SETTING Tertiary care children's hospital. PATIENTS Patients from 1 to 18 years who had formal echocardiography within 72 hours of ICU admission and who were intubated and on vasoactive infusions at the time of the study. Patients were stratified into two cardiac function groups: 1) near-normal cardiac function and 2) depressed cardiac function. METHODS Clinical variables were abstracted from the electronic medical record and placed in time sequence relative to echocardiography. Vasoactive and fluid management strategies in place before echocardiography were associated with markers of tissue perfusion and volume overload. Management changes after echocardiography were characterized and associated with outcomes. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Among patients eventually found to have depressed cardiac function, the use of vasoconstrictors was associated with worse lactate clearance and oxygen extraction ratio. Use of vasoconstrictors in this cohort was also associated with a more liberal fluid management strategy, evidence of increased lung water, and a worse Spo2/Fio2. An echocardiogram demonstrated depressed cardiac function was likely to be followed by management changes that favored inotropes and more conservative fluid administration. Patients with depressed cardiac function who were switched to inotropes were more likely to be extubated and to wean off vasoactive support compared with those patients who remained on vasoconstrictors. CONCLUSIONS Among patients with depressed cardiac function, alterations in management strategy after echocardiography are associated with shortened duration of intensive care interventions.

Abstract
There is a paucity of literature on the prevalence, predictors, prognostic markers, and outcomes of sepsis-induced myocardial dysfunction (SMD) in pediatric septic shock. The objectives of our study were to estimate the prevalence of SMD in pediatric septic shock by point-of-care functional echocardiography (POCFE) and to study the association of SMD with severity of illness, organ dysfunctions, and outcomes. This prospective, observational study was conducted over a period of 1 year (from July 2018 to July 2019) in a 12-bed, tertiary pediatric intensive care unit (PICU) of an academic and referral hospital in South India. Children presenting with septic shock were enrolled in the study. POCFE was done within 6 hours of PICU admission and patients were categorized as having SMD based on POCFE findings. The prevalence of SMD (left ventricle ± right ventricle) was 32% (32/100). More than half of the children (54.5%) died in SMD group, whereas only 7.5% died in non-SMD group ( p < 0.001). SMD was associated with higher organ dysfunctions, worse patient outcomes, and was found to be an independent predictor of mortality. The median lactate levels were higher in SMD group (3.15 [2.7, 5] vs. 2 [1.3, 2.7], p < 0.001) as compared with non-SMD group. We observed significantly lower median lactate clearance at 6 hours in SMD than non-SMD (30.0% [-14.44, 44.22] vs. 59.8% [45.83, 71.43], p < 0.001). Lactate levels at 6 hours with a threshold of 2.4 mmol/L was a good predictor of SMD with sensitivity and specificity of 73 and 80%, respectively. SMD is not an uncommon entity in children with septic shock. SMD was associated with worse patient outcomes, organ dysfunction, and mortality. Serum lactate trends may predict SMD and can be used as prognosticate markers as well.

Abstract
Background To evaluate the role of ultrasound during initial fluid resuscitation along with clinical guidance in reducing the incidence of fluid overload on day 3 in children with septic shock. Materials and methods It was a prospective, parallel limb open-labeled randomized controlled superiority trial done in the PICU of a government-aided tertiary care hospital in Eastern India. Patient enrolment took place between June 2021 and March 2022. Fifty-six children aged between 1 month and 12 years, with proven or suspected septic shock, were randomized to receive either ultrasound-guided or clinically guided fluid boluses (1:1 ratio) and subsequently followed up for various outcomes. The primary outcome was frequency of fluid overload on day 3 of admission. The treatment group received ultrasound-guided fluid boluses along with the clinical guidance and the control group received the same but without ultrasound guidance upto 60 mL/kg of fluid boluses. Results The frequency of fluid overload on day 3 of admission was significantly lower in the ultrasound group (25% vs 62%, p = 0.012) as was the median (IQR) cumulative fluid balance percentage on day 3 [6.5 (3.3-10.3) vs 11.3 (5.4-17.5), p = 0.02]. The amount of fluid bolus administered was also significantly lower by ultrasound [median 40 (30-50) vs 50 (40-80) mL/kg, p = 0.003]. Resuscitation time was shorter in the ultrasound group (13.4 ± 5.6 vs 20.5 ± 8 h, p = 0.002). Conclusion Ultrasound-guided fluid boluses were found to be significantly better than clinically guided therapy, in preventing fluid overload and its associated complications in children with septic shock. These factors make ultrasound a potentially useful tool for resuscitation of children with septic shock in the PICU.

Abstract
OBJECTIVES Shock is a life-threatening condition in children in low- and middle-income countries (LMIC), with several controversies. This systematic review summarizes the etiology, pathophysiology and mortality of shock in children in LMIC. METHODS We searched for studies reporting on children with shock in LMIC in PubMed, Embase and through snowballing (up to 1 October 2019). Studies conducted in LMIC that reported on shock in children (1 month-18 years) were included. We excluded studies only containing data on neonates, cardiac surgery patients or iatrogenic causes. We presented prevalence data, pooled mortality estimates and conducted subgroup analyses per definition, region and disease. Etiology and pathophysiology data were systematically collected. RESULTS We identified 959 studies and included 59 studies of which six primarily studied shock. Definitions used for shock were classified into five groups. Prevalence of shock ranged from 1.5% in a pediatric hospital population to 44.3% in critically ill children. Pooled mortality estimates ranged between 3.9-33.3% for the five definition groups. Important etiologies included gastroenteritis, sepsis, malaria and severe anemia, which often coincided. The pathophysiology was poorly studied but suggests that in addition to hypovolemia, dissociative and cardiogenic shock are common in LMIC. CONCLUSIONS Shock is associated with high mortality in hospitalized children in LMIC. Despite the importance few studies investigated shock and as a consequence limited data on etiology and pathophysiology of shock is available. A uniform bedside definition may help boost future studies unravelling shock etiology and pathophysiology in LMIC.

Abstract
OBJECTIVES Fluid overload increases morbidity and mortality in PICU patients. Active fluid removal improves the prognosis but may worsen organ dysfunction. Preload dependence in adults does predict hemodynamic instability induced by a fluid removal challenge (FRC). We sought to investigate the diagnostic accuracy of dynamic and static markers of preload in predicting hemodynamic instability and reduction of stroke volume during an FRC in children. We followed the Standards for Reporting of Diagnostic Accuracy statement to design conduct and report this study. DESIGN Prospective noninterventional cohort study. SETTINGS From June 2017 to April 2019 in a pediatric cardiac ICU in a tertiary hospital. PATIENTS Patients 8 years old or younger, with symptoms of fluid overload after cardiac surgery, were studied. INTERVENTIONS We confirmed preload dependence by echocardiography before and during a calibrated abdominal compression test. We then performed a challenge to remove 10-mL/kg fluid in less than 120 minutes with an infusion of diuretics. Hemodynamic instability was defined as a decrease of 10% of mean arterial pressure. MEASUREMENT AND MAIN RESULTS We compared patients showing hemodynamic instability with patients remaining stable, and we built receiver operative characteristic (ROC) curves. Among 58 patients studied, 10 showed hemodynamic instability. The area under the ROC curve was 0.55 for the preload dependence test (95% CI, 0.34-0.75). Using a threshold of 10% increase in stroke volume index (SVi) during calibrated abdominal compression, the specificity was 0.30 (95% CI, 0.00-0.60) and the sensitivity was 0.77 (95% CI, 0.65-0.88). Mean arterial pressure variation and SVi variation were not correlated during fluid removal; r = 0.19; 95% CI -0.07 to 0.43; p = 0.139. CONCLUSIONS Preload dependence is not accurate to predict hemodynamic instability during an FRC. Our data do not support a reduction in intravascular volume being mainly responsible for the reduction in arterial pressure during an FRC in children.

Abstract
Objectives: Point of care ultrasound (POCUS) in adult critical care environments has become the standard of care in many hospitals. A robust literature shows its benefits for both diagnosis and delivery of care. The utility of POCUS in the pediatric intensive care unit (PICU), however, is understudied. This study describes in a series of PICU patients the clinical indications, protocols, findings and impact of pediatric POCUS on clinical management. Design: Retrospective analysis of 200 consecutive POCUS scans performed by a PICU physician. Patients: Pediatric critical care patients who required POCUS scans over a 15-month period. Setting: The pediatric and cardiac ICUs at a tertiary pediatric care center. Interventions: Performance of a POCUS scan by a pediatric critical care attending with advanced training in ultrasonography. Measurement and Main Results: A total of 200 POCUS scans comprised of one or more protocols (lung and pleura, cardiac, abdominal, or vascular diagnostic protocols) were performed on 155 patients over a 15-month period. The protocols used for each scan reflected the clinical question to be answered. These 200 scans included 133 thoracic protocols, 110 cardiac protocols, 77 abdominal protocols, and 4 vascular protocols. In this series, 42% of scans identified pathology that required a change in therapy, 26% confirmed pathology consistent with the ongoing plans for new therapy, and 32% identified pathology that did not result in initiation of a new therapy. Conclusions: POCUS performed by a trained pediatric intensivist provided useful clinical information to guide patient management.

Abstract
OBJECTIVES Determine level of agreement among clinical signs of shock type, identify which signs clinicians prioritize to determine shock type and select vasoactive medications, and test the association of shock type-vasoactive mismatch with prolonged organ dysfunction or death (complicated course). DESIGN Retrospective observational study. SETTING Single large academic PICU. PATIENTS Patients less than 18 years treated on a critical care sepsis pathway between 2012 and 2016. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Agreement among clinical signs (extremity temperature, capillary refill, pulse strength, pulse pressure, and diastolic blood pressure) was measured using Fleiss and Cohen's κ. Association of clinical signs with shock type and shock type-vasoactive mismatch (e.g., cold shock treated with vasopressor rather than inotrope) with complicated course was determined using multivariable logistic regression. Of 469 patients, clinicians determined 307 (65%) had warm and 162 (35%) had cold shock. Agreement across all clinical signs was low (κ, 0.25; 95% CI, 0.20-0.30), although agreement between extremity temperature, capillary refill, and pulse strength was better than with pulse pressure and diastolic blood pressure. Only extremity temperature (adjusted odds ratio, 26.6; 95% CI, 15.5-45.8), capillary refill (adjusted odds ratio, 15.7; 95% CI, 7.9-31.3), and pulse strength (adjusted odds ratio, 21.3; 95% CI, 8.6-52.7) were associated with clinician-documented shock type. Of the 86 patients initiated on vasoactive medications during the pathway, shock type was discordant from vasoactive medication (κ, 0.14; 95% CI, -0.03 to 0.31) and shock type-vasoactive mismatch was not associated with complicated course (adjusted odds ratio, 0.3; 95% CI, 0.1-1.02). CONCLUSIONS Agreement was low among common clinical signs used to characterize shock type, with clinicians prioritizing extremity temperature, capillary refill, and pulse strength. Although clinician-assigned shock type was often discordant with vasoactive choice, shock type-vasoactive mismatch was not associated with complicated course. Categorizing shock based on clinical signs should be done cautiously.

Abstract
Background Sepsis-induced myocardial dysfunction has implications on outcome. For lack of echocardiography in resource-limited settings, myocardial biomarkers may be an alternative monitoring tool. Objective This study was planned to explore the longitudinal behavior of creatine phosphokinase-MB (CPK-MB) in children with sepsis with and without shock, and its correlation with clinical and echocardiographic parameters over the first 10 days. Design Prospective observational study. Setting Tertiary care hospital in a lower-middle-income economy of South Asia. Patients Children (3 months to 12 years) with nonshock sepsis (NSS) (n = 40) and septic shock survivors (SSSs) (n = 40) after optimal resuscitation. Patients with catecholamine refractory shock, preexisting heart disease, and cardiorespiratory event within the past 1 month were excluded from the study. Measurements and main results Pediatric logistic organ dysfunction (PeLOD) score, vasoactive inotrope score (VIS), CPK-MB, and echocardiographic measures of myocardial function were recorded on days 1, 3, 7, and 10. Echocardiography was repeated at 1 month. Both groups were similar at baseline. The SSSs had higher CPK-MB (180 vs 53 IU/L; p < 0.001) and PeLOD score (2 ± 0.4 vs 11.7 ± 5.1, p < 0.001) on day 1 compared to the NSS children. More than half of the SSS and none of the NSS patients had myocardial dysfunction. Reduction in CPK-MB over 10 days correlated well with improvement in PeLOD (p < 0.01), VIS (p = 0.04), and echocardiographic measures of myocardial dysfunction (p < 0.05) among SSSs. At 1 month follow-up, all had normal echocardiography. Conclusion The SSSs had markedly elevated CPK-MB, and its fall paralleled the improvement in clinical status and myocardial dysfunctions. The CPK-MB could be a potential monitoring tool for septic cardiomyopathy in resource-limited settings. How to cite this article Baranwal AK, Deepthi G, Rohit MK, Jayashree M, Angurana SK, Kumar-M P.

Abstract
Objective Follow-up of cardiac index and systemic vascular resistance index by bedside
echocardiography until resuscitation. Methods A set of hemodynamic parameters was obtained, including cardiac output,
stroke volume, cardiac index, systemic vascular resistance index, velocity
time integral, myocardial performance index, capillary refill time, and
heart rate at 0 hours after fluid boluses before the start of inotropes, and
followed up after 6 hours and 24 hours. Results Included were 45 patients with community-acquired septic shock. Septic foci
were gastroenteritis (24%), intestinal perforation requiring emergency
surgery (24%), pneumonia (20%), central nervous system infection (22%) and
soft tissue infection (8%). Klebsiella and Enterobacter were the most
frequent isolates. We estimated the factors affecting the cardiac index:
high central venous pressure at zero time (r = 0.33, p = 0.024) and
persistently high heart rate at hour 6 (r = 0.33, p = 0.03). The systemic
vascular resistance index was high in most patients at 0 and 24 hours and at
the time of resuscitation and inversely affected the cardiac index as well
as affecting the velocity time integral (r = -0.416, -0.61, 0.55 and
-0.295). Prolonged capillary refill time was a clinical predictor of the low
velocity time integral at 24 hours (r = -0.4). The mortality was 27%. Lower
systemic vascular resistance index and higher cardiac output were observed
in nonsurviving patients. Conclusion There was a persistently high systemic vascular resistance index in cold
shock patients that influenced the stroke volume index, cardiac index, and
velocity time integral. The use of echocardiograms for hemodynamic
measurements is important in pediatric septic shock patients to adjust
dilators, and vasopressor doses and achieve resuscitation targets in a
timely manner.

Abstract
OBJECTIVE To evaluate the role of echocardiography in reducing shock reversal time in pediatric septic shock. METHODS A prospective study conducted in the pediatric intensive care unit of a tertiary care teaching hospital from September 2013 to May 2016. Ninety septic shock patients were randomized in a 1:1 ratio for comparing the serial echocardiography-guided therapy in the study group with the standard therapy in the control group regarding clinical course, timely treatment, and outcomes. RESULTS Shock reversal was significantly higher in the study group (89% vs. 67%), with significantly reduced shock reversal time (3.3 vs. 4.5 days). Pediatric intensive care unit stay in the study group was significantly shorter (8±3 vs. 14±10 days). Mortality due to unresolved shock was significantly lower in the study group. Fluid overload was significantly lower in the study group (11% vs. 44%). In the study group, inotropes were used more frequently (89% vs. 67%) and initiated earlier (12[0.5-24] vs. 24[6-72]h) with lower maximum vasopressor inotrope score (120[30-325] vs. 170[80-395]), revealing predominant use of milrinone (62% vs. 22%). CONCLUSION Serial echocardiography provided crucial data for early recognition of septic myocardial dysfunction and hypovolemia that was not apparent on clinical assessment, allowing a timely management and resulting in shock reversal time reduction among children with septic shock.

Abstract
Objective: To determine the indication and necessity of echocardiographic assessment and therapeutic interventions in critically ill children. Methods: A total of 140 children, including 75 mechanically ventilated (MV) and 65 spontaneously breathing (SB) children, who were admitted consecutively from March to August 2013 were evaluated prospectively. Data regarding the indication for echocardiography and therapeutic approaches used were documented. For evaluating disease severity, the Pediatric Risk of Mortality Score III (PRISM) was ascertained. The correlation between PRISM score and the requirement of echocardiographic evaluations were analyzed. Results: Patients ages were between 45 days to 18 years. The male-to-female ratio was 1.33. In 35.4% patients who underwent echocardiographic evaluation, no definitive alteration occurred in treatment approach, whereas in the remaining 64.6% patients, decisive or supplemental information was gathered. Echocardiography was indicated in 88% MV children and 46.2% SB children. Echocardiographic evaluation was necessary in MV children and there was a positive correlation between the PRISM score and the requirement of echocardiographic assessment (p<0.001). Conclusion: Echocardiographic evaluation is an invaluable tool especially in MV children and the requirement of echocardiographic assessment increases according to clinical severity. Basic training for intensivists in this procedure is crucial and needs to be improved and supported in critically ill.

Abstract
OBJECTIVE The aim of this study was to verify the association of echocardiogram, ferritin, C-reactive protein, and leukocyte count with unfavorable outcomes in pediatric sepsis. METHODS A prospective cohort study was carried out from March to December 2014, with pediatric critical care patients aged between 28 days and 18 years. Inclusion criteria were diagnosis of sepsis, need for mechanical ventilation for more than 48h, and vasoactive drugs. Serum levels of C-reactive protein, ferritin, and leukocyte count were collected on the first day (D0), 24h (D1), and 72h (D3) after recruitment. Patients underwent transthoracic echocardiography to determine the ejection fraction of the left ventricle on D1 and D3. The outcomes measured were length of hospital stay and in the pediatric intensive care unit, mechanical ventilation duration, free hours of VM, duration of use of inotropic agents, maximum inotropic score, and mortality. RESULTS Twenty patients completed the study. Patients with elevated ferritin levels on D0 had also fewer ventilator-free hours (p=0.046) and higher maximum inotropic score (p=0.009). Patients with cardiac dysfunction by echocardiogram on D1 had longer hospital stay (p=0.047), pediatric intensive care unit stay (p=0.020), duration of mechanical ventilation (p=0.011), maximum inotropic score (p=0.001), and fewer ventilator-free hours (p=0.020). CONCLUSION Cardiac dysfunction by echocardiography and serum ferritin value was significantly associated with unfavorable outcomes in pediatric patients with sepsis.

Abstract
OBJECTIVES To evaluate whether lactate clearance and normalization during emergency care of pediatric sepsis is associated with lower rates of persistent organ dysfunction. STUDY DESIGN This was a prospective cohort study of 77 children <18 years of age in the emergency department with infection and acute organ dysfunction per consensus definitions. In consented patients, lactate was measured 2 and/or 4 hours after an initial lactate; persistent organ dysfunction was assessed through laboratory and physician evaluation at 48 hours. A decrease of ≥ 10% from initial to final level was considered lactate clearance; a final level < 2 mmol/L was considered lactate normalization. Relative risk (RR) with 95% CIs, adjusted in a log-binomial model, was used to evaluate associations between lactate clearance/normalization and organ dysfunction. RESULTS Lactate normalized in 62 (81%) patients and cleared in 70 (91%). The primary outcome, persistent 48-hour organ dysfunction, was present in 32 (42%). Lactate normalization was associated with decreased risk of persistent organ dysfunction (RR 0.46, 0.29-0.73; adjusted RR 0.47, 0.29-0.78); lactate clearance was not (RR 0.70, 0.35-1.41; adjusted RR 0.75, 0.38-1.50). The association between lactate normalization and decreased risk of persistent organ dysfunction was retained in the subgroups with initial lactate ≥ 2 mmol/L and hypotension. CONCLUSIONS In children with sepsis and organ dysfunction, lactate normalization within 4 hours was associated with decreased persistent organ dysfunction. Serial lactate level measurement may provide a useful prognostic tool during the first hours of resuscitation in pediatric sepsis.

Enzymatic changes in myosin regulatory proteins may explain vasoplegia in terminally ill patients with sepsis. Biosci Rep 2016; 36:BSR20150207.

Abstract
The current study was conducted with the hypothesis that failure of maintenance of the vascular tone may be central to failure of the peripheral circulation and spiralling down of blood pressure in sepsis. Namely, we examined the balance between expression of myosin light chain (MLC) phosphatase and kinase, enzymes that regulate MLCs dephosphorylation and phosphorylation with a direct effect on pharmacomechanical coupling for smooth muscle relaxation and contraction respectively. Mechanical recordings and enzyme immunoassays of vascular smooth muscle lysates were used as the major methods to examine arterial biopsy samples from terminally ill sepsis patients. The results of the present study provide evidence that genomic alteration of expression of key regulatory proteins in vascular smooth muscles may be responsible for the relentless downhill course in sepsis. Down-regulation of myosin light chain kinase (MLCK) and up-regulation of MLCK may explain the loss of tone and failure to mount contractile response in vivo during circulation. The mechanical studies demonstrated the inability of the arteries to develop tone when stimulated by phenylephrine in vitro. The results of our study provide indirect hint that control of inflammation is a major therapeutic approach in sepsis, and may facilitate to ameliorate the progressive cardiovascular collapse.

Abstract
OBJECTIVE Echocardiography has become an indispensable bedside diagnostic tool in the realm of pediatric intensive care units (PICU). It has proven to be an influential factor in the formula of clinical decision-making. This study aimed to delineate the impact of echocardiography on the management of critically ill pediatric patients in the PICU at Sultan Qaboos University Hospital, Oman. METHOD This was a retrospective cohort study conducted in a five-bed PICU. Patients admitted to the PICU from January of 2011 to December of 2012 were reviewed. Those who have undergone bedside echocardiography during their ICU stay were recruited. Electronic patient record was used as data source. RESULTS Over a-24-month period, 424 patients were admitted in this PICU. One hundred and one clinically indicated transthoracic echocardiograms were performed. 81.8% of these presented new findings (n=82) that significantly impacted the clinical decision of patient management, namely, alteration in drug therapy and procedure, whereas no difference in the management was yielded in the remaining 17.8% of the studied cases. CONCLUSIONS Echocardiography had a significant impact on the management of PICU patients. Such salutary effect was consequently reflected on the outcome. Pediatric intensivists are encouraged to acquire such bedside skill.

Abstract
AIMS We previously reported that vasodilatation was common in pediatric septic shock, regardless of whether they were warm or cold, providing a rationale for early norepinephrine (NE) to increase venous return (VR) and arterial tone. Our primary aim was to evaluate the effect of smaller fluid bolus plus early-NE versus the American College of Critical Care Medicine (ACCM) approach to more liberal fluid boluses and vasoactive-inotropic agents on fluid balance, shock resolution, ventilator support and mortality in children with septic shock. Secondly, the impact of early NE on hemodynamic parameters, urine output and lactate levels was assessed using multimodality-monitoring. METHODS In keeping with the primary aim, the early NE group (N-27) received NE after 30ml/kg fluid, while the ACCM group (N-41) were a historical cohort managed as per the ACCM Guidelines, where after 40-60ml/kg fluid, patients received first line vasoactive-inotropic agents. The effect of early-NE was characterized by measuring stroke volume variation(SVV), systemic vascular resistance index (SVRI) and cardiac function before and after NE, which were monitored using ECHO + Ultrasound-Cardiac-Output-Monitor (USCOM) and lactates. RESULTS The 6-hr fluid requirement in the early-NE group (88.9+31.3 to 37.4+15.1ml/kg), and ventilated days [median 4 days (IQR 2.5-5.25) to 1day (IQR 1-1.7)] were significantly less as compared to the ACCM group. However, shock resolution and mortality rates were similar. In the early NE group, the overall SVRI was low (mean 679.7dynes/sec/cm5/m2, SD 204.5), and SVV decreased from 23.8±8.2 to 18.5±9.7, p=0.005 with NE infusion suggesting improved preload even without further fluid loading. Furthermore, lactate levels decreased and urine-output improved. CONCLUSION Early-NE and fluid restriction may be of benefit in resolving shock with less fluid and ventilator support as compared to the ACCM approach.
