Sudden cardiac arrest in infants and children:proposal for a diagnostic workup to identify the etiology. An 18-year multicenter evaluation in the Netherlands

Sudden cardiac arrest (SCA) studies are often population-based, limited to sudden cardiac death, and excluding infants. To guide prevention opportunities, it is essential to be informed of pediatric SCA etiologies. Unfortunately, etiologies frequently remain unresolved. The objectives of this study were to determine paediatric SCA etiology, and to evaluate the extent of post-SCA investigations and to assess the performance of previous cardiac evaluation in detecting conditions predisposing to SCA. In a retrospective cohort (2002–2019), all children 0–18 years with out-of-hospital cardiac arrest (OHCA) referred to Erasmus MC Sophia Children's Hospital or the Amsterdam UMC (tertiary-care university hospitals), with cardiac or unresolved etiologies were eligible for inclusion. SCA etiologies, cardiac and family history and etiologic investigations in unresolved cases were assessed. The etiology of arrest could be determined in 52% of 172 cases. Predominant etiologies in children ≥ 1 year (n = 99) were primary arrhythmogenic disorders (34%), cardiomyopathies (22%) and unresolved (32%). Events in children &lt; 1 year (n = 73) were largely unresolved (70%) or caused by cardiomyopathy (8%), congenital heart anomaly (8%) or myocarditis (7%). Of 83 children with unresolved etiology a family history was performed in 51%, an autopsy in 51% and genetic testing in 15%. Pre-existing cardiac conditions presumably causative for SCA were diagnosed in 9%, and remained unrecognized despite prior evaluation in 13%. Conclusion: SCA etiology remained unresolved in 83 of 172 cases (48%) and essential diagnostic investigations were often not performed. Over one-fifth of SCA patients underwent prior cardiac evaluation, which did not lead to recognition of a cardiac condition predisposing to SCA in all of them. The diagnostic post-SCA approach should be improved and the proposed standardized pediatric post-SCA diagnostics protocol may ensure a consistent and systematic evaluation process increasing the diagnostic yield. What is Known: • Arrests in infants remain unresolved in most cases. In children &gt; 1 year, predominant etiologies are primary arrhythmia disorders, cardiomyopathy and myocarditis. • Studies investigating sudden cardiac arrest are often limited to sudden cardiac death (SCD) in 1 to 40 year old persons, excluding infants and successfully resuscitated children. What is New: • In patients with unresolved SCA events, the diagnostic work up was often incompletely performed. • Over one fifth of victims had prior cardiac evaluation before the arrest, with either a diagnosed cardiac condition (9%) or an unrecognized cardiac condition (13%).

Efficacy of a loading dose of IV salbutamol in children with severe acute asthma admitted to a PICU:a randomized controlled trial

The optimal dose regimen for intravenous (IV) treatment in children with severe acute asthma (SAA) is still a matter of debate. We assessed the efficacy of adding a salbutamol loading dose to continuous infusion with salbutamol in children admitted to a pediatric intensive care unit (PICU) with SAA. This multicentre, placebo-controlled randomized trial in the PICUs of four tertiary care children’s hospitals included children (2–18 years) with SAA admitted between 2017 and 2019. Children were randomized to receive either a loading dose IV salbutamol (15 mcg/kg, max. 750 mcg) or normal saline while on continuous salbutamol infusion. The primary outcome was the asthma score (Qureshi) 1 h after the intervention. Analysis of covariance models was used to evaluate sensitivity to change in asthma scores. Serum concentrations of salbutamol were obtained. Fifty-eight children were included (29 in the intervention group). Median baseline asthma score was 12 (IQR 10–13) in the intervention group and 11 (9–12) in the control group (p = 0.032). The asthma score 1 h after the intervention did not differ significantly between the groups (p = 0.508, β-coefficient = 0.283). The median increase in salbutamol plasma levels 10 min after the intervention was 13 μg/L (IQR 5–24) in the intervention group and 4 μg/L (IQR 0–7) in the control group (p = 0.001). Side effects were comparable between both groups. Conclusion: We found no clinical benefit of adding a loading dose IV salbutamol to continuous infusion of salbutamol, in children admitted to the PICU with SAA. Clinically significant side effects from the loading dose were not encountered.What is Known:• Pediatric asthma guidelines struggle with an evidence-based approach for the treatment of SAA beyond the initial steps of oxygen suppletion, repetitive administration of inhaled β2-agonists, and systemic steroids.• During an SAA episode, effective delivery of inhaled drugs is unpredictable due to severe airway obstruction.What is New:• This study found no beneficial effect of an additional loading dose IV salbutamol in children admitted to the PICU.• This study found no clinically significant side effects from the loading dose

Children with severe acute asthma admitted to Dutch PICUs:A changing landscape

The number of children requiring pediatric intensive care unit (PICU) admission for severe acute asthma (SAA) around the world has increased. OBJECTIVES: We investigated whether this trend in SAA PICU admissions is present in the Netherlands. METHODS: A multicenter retrospective cohort study across all tertiary care PICUs in the Netherlands. Inclusion criteria were children (2-18 years) hospitalized for SAA between 2003 and 2013. Data included demographic data, asthma diagnosis, treatment, and mortality. RESULTS: In the 11-year study period 590 children (660 admissions) were admitted to a PICU with a threefold increase in the number of admissions per year over time. The severity of SAA seemed unchanged, based on the first blood gas, length of stay and mortality rate (0.6%). More children received highflow nasal cannula (P < 0.001) and fewer children needed invasive ventilation (P < 0.001). In 58% of the patients the maximal intravenous (IV) salbutamol infusion rate during PICU admission was 1 mcg/kg/min. However, the number of patients treated with IV salbutamol in the referring hospitals increased significantly over time (P = 0.005). The proportion of steroid-naïve patients increased from 35% to 54% (P = 0.004), with a significant increase in both age groups (2-4 years [P = 0.026] and 5-17 years [P = 0.036]). CONCLUSIONS: The number of children requiring PICU admission for SAA in the Netherlands has increased. We speculate that this threefold increase is explained by an increasing number of steroid-naïve children, in conjunction with a lowered threshold for PICU admission, possibly caused by earlier use of salbutamol IV in the referring hospitals

Early microcirculatory impairment during therapeutic hypothermia is associated with poor outcome in post-cardiac arrest children: a prospective observational cohort study

This study aimed to evaluate if the microcirculation is impaired during and after therapeutic hypothermia (TH) in children with return of spontaneous circulation after cardiac arrest (CA) and to assess if microcirculatory impairment predicts mortality. This has been reported for post-CA adults, but results might be different for children because etiology, pathophysiology, and mortality rate differ. This prospective observational cohort study included consecutive, non-neonatal post-CA children receiving TH upon intensive care admission between June 2008 and June 2012. Also included were gender-matched and age-matched normothermic, control children without cardiorespiratory disease. The buccal microcirculation was non-invasively assessed with Sidestream Dark Field Imaging at the start of TH, halfway during TH, at the start of re-warming, and at normothermia. Macrocirculatory, respiratory, and biochemical parameters were also collected. Twenty post-CA children were included of whom 9 died. During hypothermia, the microcirculation was impaired in the post-CA patients and did not change over time. At normothermia, the core body temperature and the microcirculation had increased and no longer differed from the controls. Microcirculatory deterioration was associated with mortality in the post-CA patients. In particular, the microcirculation was more severely impaired at TH start in the non-survivors than in the survivors - positive predictive value: 73-83, negative predictive value: 75-100, sensitivity: 63-100%, and specificity: 70-90%. The microcirculation is impaired in post-CA children during TH and more severe impairment at TH start was associated with mortality. After the stop of TH, the microcirculation improves rapidly irrespective of outcom

Self-esteem in children and adolescents after septic shock caused by Neisseria meningitidis: scars do matter

To investigate self-esteem and its relation to scars, amputations, and orthopedic sequelae in children and adolescents long term after meningococcal septic shock (MSS) caused by Neisseria meningitidis. The Dutch versions of the Self-Perception Profile for Children (SPP-C; 8-11 years) and the Self-Perception Profile for Adolescents (SPP-A; 12-17 years) were used to assess self-esteem. The Patient and Scar Assessment Scale (PSAS) was used to evaluate scar severity. MSS boys aged 8-11 years achieved higher, more favorable scores on self-esteem, whereas same-aged MSS girls reported comparable levels of self-esteem compared with the respectively same-aged reference boys and girls. MSS boys and girls aged 12-17 years obtained unfavorable scores on self-esteem compared with respectively same-aged reference boys and girls. Overall gender did not have an effect on self-esteem. Severity of illness, age at time of illness, and age at time of follow-up were not significant predictors of self-esteem. MSS adolescents with scars reported lower global self-worth than MSS adolescents without scars. The worse MSS children evaluated their scars, the worse their outcomes on social acceptance. The worse MSS adolescents evaluated their scars, the worse their outcomes on close friendship, but the better their outcomes on social acceptance and behavioral conduct. In this cross-sectional study, favorable outcomes for self-esteem were found in MSS children, whereas MSS adolescents reported lower self-esteem compared with reference adolescents. Adolescents with scars reported lower global self-worth than MSS adolescents without scar

Short-Term Health-Related Quality of Life of Critically Ill Children Following Daily Sedation Interruption

OBJECTIVE: Our earlier pediatric daily sedation interruption trial showed that daily sedation interruption in addition to protocolized sedation in critically ill children does not reduce duration of mechanical ventilation, length of stay, or amounts of sedative drugs administered when compared with protocolized sedation only, but undersedation was more frequent in the daily sedation interruption + protocolized sedation group. We now report the preplanned analysis comparing short-term health-related quality of life and posttraumatic stress symptoms between the two groups. DESIGN: Preplanned prospective part of a randomized controlled trial. SETTING: Two tertiary medical-surgical PICUs in the Netherlands. PATIENTS: Critically ill children requiring mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Eight weeks after a child's discharge from the PICU, health-related quality of life was assessed with the validated Child Health Questionnaire and, only for children above 4 years old, posttraumatic stress was assessed with the Dutch Children's Responses to Trauma Inventory. Additionally, health-related quality of life of all study patients was compared with Dutch normative data. Of the 113 patients from two participating centers in the original study, 96 patients were eligible for follow-up and 64 patients were included (response rate, 67%). No difference was found with respect to health-related quality of life between the two study groups. None of the eight children more than 4 years old showed posttraumatic stress symptoms. CONCLUSIONS: Daily sedation interruption in addition to protocolized sedation for critically ill children did not seem to have an effect on short-term health-related quality of life. Also in view of the earlier found absence of effect on clinical outcome, we cannot recommend the use of daily sedation interruption + protocolized sedation

Long-term health-related quality of life in survivors of meningococcal septic shock in childhood and their parents

To assess long-term health-related quality of life (HR-QoL) in patients who survived meningococcal septic shock in childhood, and their parents. All consecutive patients with meningococcal septic shock requiring intensive care treatment between 1988 and 2001, and their parents. HR-QoL was assessed by the Child Health Questionnaire and the SF-36. Scores were compared with reference data of Dutch general population samples. Lower scores indicated poorer HR-QoL, higher scores more favourable HR-QoL. One hundred and forty-five patients (response rate 82%) agreed to participate (age PICU admission 3.5 years; follow-up interval 10 years; age follow-up 14.6 years (all medians)). In patients, regardless of age and of patient- versus parent-report, significantly lower scores were found mainly on physical (physical functioning, general health perception) domains and/or physical summary score. In patients or =12 years, according to patients themselves, significantly higher scores were found on psychosocial domains. As to parents themselves, we found significantly higher scores on the majority of HR-QoL scales (both physical and psychosocial). In patients who survived meningococcal septic shock in childhood significantly lower HR-QoL scores were found on the physical domains. This could indicate that the patient's disease episode and present health status had a negative impact on their present physical HR-QoL. Overall long-term HR-QoL in parents was significantly highe
