Introduction: Adequate sedation and analgesia are two crucial factors affecting recovery of intensive care patients. Improper use of sedation and analgesia in intensive care patients may adversely lead to brain oxygen desaturation. This study aims to determine cerebral oxygenation as measured by near-infrared spectroscopy (NIRS) and inotropic interventions received among mechanically ventilated children in the pediatric intensive care unit (PICU). Methods: This study is a nested case − control study in the PICU of Indonesian tertiary hospital. Children aged 1 month to 17 years on mechanical ventilation and were given sedation and analgesia were included in the study. Subjects were divided into two groups according to the protocol of the main study (Clinical Trial ID NCT04788589). Cerebral oxygenation was measured by NIRS at five time points (before sedation, 5-min, 1, 6, and 12 h after sedation). Results: Thirty-nine of the 69 subjects were categorized into the protocol group and the rest were in the control group. A decrease of >20% NIRS values was found among subjects in the protocol group at 5-min (6.7%), 1-h (11.1%), 6-h (26.3%), and 12-h (23.8%) time-point. The mean NIRS value was lower and the inotropic intervention was more common in the control group (without protocol), although not statistically significant. Conclusion: This study found that mechanically ventilated children who received sedation and analgesia based on the protocol had a greater decrease of >20% NIRS values compared to the other group. The use of sedation and analgesia protocols must be applied in selected patients after careful consideration.

RESUMO Objetivo: Analisar a correlação entre a lesão do glicocálix medida pelo nível sérico de sindecano 1 e as disfunções de órgãos avaliadas com o escore PELOD-2, assim como avaliar sua associação com a mortalidade em sepse pediátrica. Métodos: Realizou-se um estudo prospectivo observacional em um hospital terciário público. Sessenta e oito pacientes pediátricos, com diagnóstico de sepse segundo os critérios da International Pediatric Sepsis Consensus Conference, foram consecutivamente recrutados. Nos dias 1 e 5, realizaram-se dosagens dos níveis séricos de sindecano 1 e avaliação dos componentes do escore PELOD-2. Os pacientes foram seguidos por até 28 dias após o diagnóstico de sepse. Resultados: Em geral, o nível de sindecano 1 estava aumentado em todos os participantes, com nível significantemente mais elevado nos pacientes em choque (p = 0,01). O nível de sindecano 1 no dia 1 teve correlação positiva com o escore PELOD-2 no dia 1 e coeficiente de correlação de 0,35 (p = 0,003). Nos primeiros 5 dias após o diagnóstico de sepse, as alterações nos níveis de sindecano 1 tiveram correlação positiva com modificações no escore PELOD-2, com coeficiente de correlação de 0,499 (p < 0,001). Com utilização de um ponto de corte dos níveis de sindecano 1 no dia 1 ≥ 430ng/mL, a disfunção de órgãos (escore PELOD-2 ≥ 8) pôde ser predita com área sob a curva de 74,3%, sensibilidade de 78,6% e especificidade de 68,5% (p = 0,001). Conclusão: O nível de sindecano 1 no dia 1 teve correlação com o escore PELOD-2 no dia 1, porém não se associou com a mortalidade aos 28 dias. A disfunção de órgãos (PELOD-2 ≥ 8) pôde ser predita pelo nível de sindecano 1 nas primeiras 24 horas de sepse, sugerindo seu significante envolvimento na fisiopatologia da disfunção de órgãos associada à sepse.

Introduction: The fluid therapy is crucial in the treatment of critically ill children. Inadequate or excessive fluid resuscitation leads to increased mortality and morbidity, thus necessitating an accurate parameter for predicting fluid responsiveness when conducting fluid resuscitation. The inferior vena cava/abdominal aorta (IVC/Ao) ratio is suggested as a good guide for fluid resuscitation. However, the cutoff value for predicting fluid responsiveness in children has not been established. Is IVC/Ao ratio can be used to predict fluid responsiveness? Methods: The objective was to determine the accuracy and a cutoff value of IVC/Ao in predicting fluid responsiveness. A prospective cross-sectional study was conducted in the emergency room and the pediatric intensive care unit of the tertiary hospital from March to August 2017. We consecutively enrolled all critically ill children aged 1 month to 18 years' old who were hemodynamically unstable (shock). Measurements of IVC/Ao with ultrasound and stroke volume with ultrasound cardiac output monitor were obtained before and after fluid challenge. Results: Of 167 subjects enrolled in this study, only 58 subjects were included, most of whom were male (58.6%) and ranging in age from 1 to 11 months (32.8%). The mean IVC/Ao ratio before the fluid challenge in the fluid responsive group was 0.70 ± 0.053. The best cutoff of the IVC/Ao ratio is 0.675 with area under the curve 70.8% (95% confidence interval of 54.6%–87%), 75.7% sensitivity, and 61.9% specificity for predicting significant fluid responsiveness. Conclusion: The measurement of IVC/Ao is an accurate, sensitive, and specific parameter to predict fluid responsiveness. The best cut-off for the IVC/Ao ratio is 0.675.

Background. Mild elevation of serum amino-terminal pro-B-type natriuretic peptide (NT-pro-BNP) is associated with myocardial dysfunction. A significantly lower Smith–Madigan inotropic index (SMII) has been shown to accurately represent cardiac contractility among heart failure subjects. We aim to monitor the effect of fluid resuscitation on cardiac function among paediatric patients by measuring serum NT-pro-BNP and SMII. Methods. This is an observational study on 70 paediatric shock patients. NT-pro-BNP and noninvasive bedside haemodynamic monitoring were done by using an ultrasonic cardiac output monitor (USCOM, USCOM, Sydney, Australia). The presence of cardiac diseases was excluded. SMII was obtained from the USCOM. An increase in the stroke volume index (SVI) of ≥15% indicates fluid responders. Measurements were taken before and after fluid loading. Results. Preloading NT-pro-BNP and SMII category were significantly different between the fluid responsiveness group, p=0.001 and p=0.004, respectively. Higher median NT-pro-BNP (preloading NT-pro-BNP of 1175.00 (254.50–9965.00) ng/mL vs. 196.00 (65.00–509.00) ng/mL, p=0.002) was associated with fluid nonresponders (subjects >12 months old). Preloading NT-pro-BNP 12 years old. Delta NT-pro-BNP in fluid responders (15.00 (−16.00–950.00) ng/mL) did not differ from fluid nonresponders (505.00 (−797.00–1600.00) ng/mL), p=0.456. Postloading SMII >1.25 W·m−2 was associated with fluid responders (AUC: 0.683 (0.553–0.813), p = 0.011), 61.9% sensitivity, and 66.7% specificity, but not preloading SMII. Fluid responders had a higher mean postloading SMII compared to nonresponders (1.36 ± 0.38 vs. 1.10 ± 0.34, p=0.006). Conclusion. Higher NT-pro-BNP and lower SMII in the absence of cardiac diseases were associated with poor response to fluid loading. The SMII is affected by low preload conditions.
