BACKGROUND: Half of pediatric in-hospital cardiopulmonary resuscitation (CPR) events have an initial rhythm of non-pulseless bradycardia with poor perfusion. Our study objectives were to leverage granular data from the ICU-RESUScitation (ICU-RESUS) trial to: (1) determine the association of early epinephrine administration with survival outcomes in children receiving CPR for bradycardia with poor perfusion; and (2) describe the incidence and time course of the development of pulselessness.
METHODS: Prespecified secondary analysis of ICU-RESUS, a multicenter cluster randomized trial of children (< 19 years) receiving CPR in 18 intensive care units in the United States. Index events (October 2016-March 2021) lasting ≥ 2 min with a documented initial rhythm of bradycardia with poor perfusion were included. Associations between early epinephrine (first 2 min of CPR) and outcomes were evaluated with Poisson multivariable regression controlling for a priori pre-arrest characteristics. Among patients with arterial lines, intra-arrest blood pressure waveforms were reviewed to determine presence of a pulse during CPR interruptions. The temporal nature of progression to pulselessness was described and outcomes were compared between patients according to subsequent pulselessness status.
RESULTS: Of 452 eligible subjects, 322 (71%) received early epinephrine. The early epinephrine group had higher pre-arrest severity of illness and vasoactive-inotrope scores. Early epinephrine was not associated with survival to discharge (aRR 0.97, 95%CI 0.82, 1.14) or survival with favorable neurologic outcome (aRR 0.99, 95%CI 0.82, 1.18). Among 186 patients with invasive blood pressure waveforms, 118 (63%) had at least 1 period of pulselessness during the first 10 min of CPR; 86 (46%) by 2 min and 100 (54%) by 3 min. Sustained return of spontaneous circulation was highest after bradycardia with poor perfusion (84%) compared to bradycardia with poor perfusion progressing to pulselessness (43%) and bradycardia with poor perfusion progressing to pulselessness followed by return to bradycardia with poor perfusion (62%) (p < 0.001).
CONCLUSIONS: In this cohort of pediatric CPR events with an initial rhythm of bradycardia with poor perfusion, we failed to identify an association between early bolus epinephrine and outcomes when controlling for illness severity. Most children receiving CPR for bradycardia with poor perfusion developed subsequent pulselessness, 46% within 2 min of CPR onset.

BACKGROUND: Few studies have evaluated the perceptions of healthcare providers in China regarding pediatric palliative care, particularly in critical care units (PICUs), where many children receive palliative care. To evaluate the knowledge, attitudes and practices of PICU personnel in China regarding pediatric palliative care.
METHODS: This cross-sectional study was conducted in five cities in China (Shanghai, Suzhou, Chongqing, Chengdu and Yunnan) between November 2022 and December 2022.
RESULTS: The analysis included 204 participants (122 females), with 158 nurses and 46 physicians. The average knowledge, attitude and practice scores were 9.75 ± 2.90 points (possible range, 0-13 points), 38.30 ± 3.80 points (possible range, 12-60 points) and 35.48 ± 5.72 points (possible range, 9-45 points), respectively. Knowledge score was higher for physicians than for nurses (P < 0.001) and for personnel with previous training in pediatric palliative care (P = 0.005). According to structural equation modelling knowledge had a direct positive effect on attitude (β = 0.69 [0.28-1.10], p = 0.001), and indirect on practice (β = 0.82 [0.36-1.28], p < 0.001); attitude had significant effect on practice as well (β = 1.18 [0.81-1.56], p < 0.001).
CONCLUSIONS: There is room for improvement in the knowledge, attitudes and practices of PICU personnel in China regarding pediatric palliative care. The findings of this study may facilitate the design and implementation of targeted education/training programs to better inform physicians and nurses in China about pediatric palliative care.

Background Enteral nutrition (EN) represents the preferred modality for nutrient administration in critically ill patients. However, it is fraught with challenges such as delayed initiation and recurrent interruptions, which can significantly impact patient clinical outcomes. A substantial proportion of these interruptions can be mitigated. In the present investigation, our objective was to scrutinize the practice of EN in the Pediatric Intensive Care Unit (PICU). We sought to ascertain the frequency and underlying causes of EN interruptions and assess their ramifications for nutrient delivery. Study design We conducted an observational study within the PICU of Mahatma Gandhi Mission\'s (MGM) Medical College and Hospital, Aurangabad. The study encompassed children admitted to the PICU for a period exceeding 24 hours who were receiving enteral feeds. We documented the time of commencing EN from the point of PICU admission, instances of enteral feeding interruptions, the number and duration of each interruption episode, and the reasons behind these interruptions. Subsequently, we categorized the causes of feeding interruptions into avoidable and non-avoidable determinants. Results Out of the 100 patients enrolled in this study, only 34% presented with normal nutritional status upon admission. Sixty-five percent of patients had their nutritional support initiated within the first 48 hours of admission to the PICU. The median duration from PICU admission to the initiation of EN was 32.5 hours, with a median interruption duration per patient of 40.96 hours. Common causes of interruptions included radiological procedures, respiratory distress, altered sensorium, presence of gastric aspirates, and surgical procedures. Upon analysis, it was determined that a substantial majority, constituting 74%, of these interruptions were avoidable. Conclusions The primary challenges associated with EN in the PICU encompass delayed initiation of enteral feeds and frequent interruptions. Importantly, a significant proportion of these issues are avoidable.

BACKGROUND: Nonpharmacological interventions for COVID-19 could reduce the incidence of children hospitalized in pediatric intensive care units (PICU) and the incidence of children with bacterial infections. This study aimed to evaluate changes in the bacterial profile of children in PICU before and during the COVID-19 pandemics.
METHODS: This is a retrospective study, involving clinical data of children with positive bacterial cultures admitted to the PICU respectively in 2019 and 2021.
RESULTS: In total 652 children were included in this study. The total number of hospitalized patients and the incidence of bacteria-positive children in 2021 were lower than those in 2019. There were no significant differences in the ratio of Gram-positive bacterial infection, Gram-negative bacteria infection or fungi infection between the two years. The rate of Streptococcus pneumoniae in 2021 was higher than that in 2019(p = 0.127). The incidence of Haemophilus influenzae in hospitalized patients decreased with a downward trend(p = 0.002). The distribution of previous underlying diseases in children admitted to PICU with different outcomes of bacterial infection between the two years were homogeneous (p > 0.05).
CONCLUSIONS: After the implementation of COVID-19 isolation, prevention and control measures, the number of hospitalizations and bacterial infections in PICU decreased, which may be due to changes in population\'s behavior patterns. Meanwhile, the incidence of Haemophilus influenzae in hospitalized patients decreased with a downward trend.

Introduction. Infant botulism (IB) is the most common form of human botulism in Argentina. Our objective was to describe the main aspects of diagnosis and management of patients with IB admitted to the pediatric intensive care unit (PICU). Methods. Observational, descriptive, and retrospective study. The PICU database with IB diagnosis in 2005-2020 period was used. Demographic variables, diagnostic methods, days of conventional mechanical ventilation (CMV), non-invasive ventilation (NIV), length of stay in the PICU and mortality upon hospital discharge were recorded. Results. In total, 21 patients with IB were recorded; 14 were male, their median age was 5 months (IQR: 2-6 m). Diagnosis was made by bioassay, and the toxin was identified in the serum of 12 patients. Only 1 patient did not require CMV; 1 patient had a tracheostomy; 18 patients received antibiotics; 5 received NIV. No patient was administered antitoxin and no patient died. The median length of stay in the hospital was 66 days (IQR: 42-76); in the PICU, 48 days (IQR: 29-78); and the median use of CMV, 37 days (IQR: 26-64). The delay until diagnostic confirmation was 15.8 ± 4.8 days. Conclusions. All patients were diagnosed using the bioassay technique, which resulted in a diagnostic delay that exceeds the recommended period for the administration of a specific treatment. No patient received a specific treatment. IB was related to a low mortality, but also to prolonged use o  MV and length of hospital stay, which were associated with cross infections and frequent antibiotic use.
Introducción. El botulismo del lactante (BL) es la forma más frecuente de botulismo humano en Argentina. El objetivo es describir aspectos esenciales del diagnóstico y tratamiento de pacientes con BL internados en el servicio de terapia intensiva pediátrica (STIP). Métodos. Estudio observacional, descriptivo y retrospectivo. Se utilizó la base de datos del STIP con diagnóstico de BL en el período 2005-2020. Se registraron variables demográficas, métodos de diagnóstico, días de asistencia respiratoria mecánica convencional (ARMC), de ventilación no invasiva (VNI), estadía en STIP, mortalidad al alta hospitalaria. Resultados. Se registraron 21 pacientes con BL; 14 pacientes fueron varones, con una mediana de edad de 5 meses (RIC 2-6 m). El diagnóstico se realizó mediante técnica de bioensayo y se detectó la toxina en suero en 12 pacientes. Uno solo no requirió ARMC; 1 paciente fue traqueostomizado; 18 pacientes recibieron antibióticos; 5 recibieron VNI. Ningún paciente recibió antitoxina y no hubo fallecidos. La mediana de estadía hospitalaria fue 66 días (RI: 42-76); de internación en STIP, 48 días (RI: 29-78); y de ARMC, 37 días (RI: 26-64). La demora en la confirmación diagnóstica fue 15,8 ± 4,8 días. Conclusiones. La totalidad de los pacientes fueron diagnosticados con la técnica de bioensayo, que generó un tiempo de demora diagnóstica que excede los lapsos recomendados para la administración del tratamiento específico. Ningún paciente recibió tratamiento específico. El BL presentó baja mortalidad, pero tiempos de ARM e internación prolongados, que se asocian a infecciones sobreagregadas y uso frecuente de antibióticos.

Introduction. In pediatric intensive care units, a large number of drugs are used, many of which are prescribed for condition beyond those established in their summary of product characteristics (off-label and unlicensed drug prescriptions). The objective of this study was to describe drug use and estimate the prevalence of off-label and unlicensed drugs in a pediatric intensive care unit of a tertiary care Spanish hospital. Population and methods. Cross-sectional, observational study with a single cohort of children admitted to a pediatric intensive care unit. The study was conducted in 2017. Each drug prescription, its conditions of use and administration were reviewed. In addition, the summary of product characteristics of drugs used were analyzed in order to identify whether they were used according to their conditions of authorization, or whether they were used in an off-label or unlicensed manner. Results. The sample included 97 patients. At least one off-label or unlicensed drug was administered to 74.2% (n = 72) of patients; 23.8% (n = 243) corresponded to off-label prescriptions and 8.7% (n = 89), unlicensed prescriptions. A sub-analysis by age group showed that the age group that received a higher number of total prescriptions (n = 611) and a higher percentage of off-label and/or unlicensed drug prescriptions (38.4%) was under 2 years of age. Conclusions. Off-label and/or unlicensed drug prescription is a common practice in the pediatric intensive care unit. This study allowed us to document the complexity of therapeutics in children.
Introducción. En las unidades de cuidados intensivos pediátricos, se utiliza gran cantidad de medicamentos, muchos prescritos fuera de las condiciones establecidas en su ficha técnica (prescripciones off-label y unlicensed). El objetivo de este estudio fue describir el uso de medicamentos y estimar la prevalencia de fármacos off-label y unlicensed en una unidad de cuidados intensivos pediátricos de un hospital de tercer nivel español. Población y métodos. Estudio transversal, observacional, de una cohorte de niños ingresados en una unidad de cuidados intensivos pediátricos. El estudio se llevó a cabo en 2017. Se revisó cada fármaco prescrito, sus condiciones de uso y administración. Además, se analizaron las fichas técnicas de los fármacos implicados con la finalidad de identificar si el uso de los medicamentos se realizaba según sus condiciones de autorización, o bien se hacía fuera de prospecto (off-label) o como unlicensed. Resultados. La muestra fue de 97 pacientes. El 74,2 % (n = 72) de los pacientes recibieron algún fármaco off-label o unlicensed. El 23,8 % (n = 243) de las prescripciones fueron off-label y el 8,7 % (n = 89), unlicensed. El subanálisis realizado por grupos de edad mostró que el grupo de edad que recibió mayor número de prescripciones totales (n = 611) y el mayor porcentaje de fármacos prescritos en condiciones off-label y/o unlicensed (38,4 %) fue el de menores de 2 años. Conclusiones. La prescripción de fármacos off-label y/o unlicensed es una práctica habitual en la unidad de cuidados intensivos pediátricos. Este estudio permite documentar la complejidad de la terapéutica en niños.

Introduction Propofol has long been used as an anesthetic agent during pediatric surgery. Its use in pediatric intensive care units has been largely controversial. A beneficial use of propofol is to facilitate weaning of other pain and sedation infusions such as opiates and benzodiazepines. However, some have advocated to not use propofol due to fear of possible adverse effects including propofol infusion syndrome and hemodynamic instability. The purpose of this study was to determine both the safety of propofol infusions in critically ill pediatric patients, as well as the change in the requirement of other pain and sedation infusions by use of a propofol infusion. Methods Single-center, retrospective data (January 2011 to January 2020) was obtained manually using a study-specific data extraction tool created for electronic medical records. The data obtained included variables of interest that measured physiological parameters and pain/sedation infusion (morphine, fentanyl, hydromorphone, midazolam, and dexmedetomidine) rates during three time periods: before propofol initiation, immediately after discontinuation, and four hours after discontinuation. The physiological parameters were then compared to the pain and sedation infusion rates using paired Wilcoxon signed-rank tests. Results There was a total of 33 patients with an average age of 11.1 years who were given a median initial propofol infusion of 50 mcg/kg/min with a peak dose of 75 mcg/kg/min over an average of eight hours. Age had a weak and insignificant correlation with initial rate and duration and a moderate and significant correlation with peak rate and duration. Physiological parameters did not vary at any time point measured. There was a significant reduction in other pain and sedation infusions after discontinuation of propofol. Conclusion Propofol infusions are hemodynamically tolerated and the majority of patients who are on other pain and sedation infusions tolerate complete discontinuation of these infusions following propofol discontinuation.

OBJECTIVE: We aimed to evaluate and compare the prognostic performance of common pediatric mortality scoring systems (the Pediatric Index of Mortality 2 [PIM2], PIM3, Pediatric Risk of Mortality [PRISM], and PRISM4 scores) to determine which is the most applicable score in our pediatric study cohort.
METHODS: This prospective observational multicenter cohort study was conducted in four tertiary-care pediatric intensive care units (PICUs) in Turkey. All children, between 1 month and 16 years old, admitted to the participating PICUs between October 1, 2019, and March 31, 2020, were included in the study. Discrimination between death and survival was assessed by area under the receiver operating characteristic plot (AUC) for each model. The Hosmer-Lemeshow goodness-of-fit (GOF) test was used to assess the calibration of the models, RESULTS: A total of 570 patients (median age 35 months) were enrolled in the study. The observed mortality rate was 8.2% (47/570). The standardized mortality ratio (SMR) of PIM2, PIM3, PRISM, and PRISM4 with 95% confidence interval (CI) were 0.94 (0.68-1.23), 1.27 (0.93-1.68), 0.86 (0.63-1.13), and 1.5 (1.10-1.97), respectively. The AUC with 95% CI was 0.934 (0.91-0.96) for PIM2, 0.934 (0.91-0.96) for PIM3, 0.917 (0.88-0.95) for PRISM, and 0.926 (0.88-0.97) for PRISM4 models. The Hosmer-Lemeshow test showed that the difference between observed and predicted mortality by PIM3 (p = 0.003) and PRISM4 (p = 0.008) was statistically significant whereas PIM2 (p = 0.28) and PRISM (p = 0.62) showed good calibration.
CONCLUSIONS: The overall performance of (both discrimination and calibration) PRISM and PIM2 scoring systems in Turkish pediatric patients aged 1 month to 16 years was accurate and had the best fit for risk groups according to our study. Although PIM3 and PRISM4 have good discriminatory power, their calibration was very poor in our study cohort.

OBJECTIVE: To examine medical and psychosocial risk factors associated with the development of acute stress in parents of patients unexpectedly admitted to the PICU.
METHODS: Cross-sectional observational study.
METHODS: Two tertiary care children\'s hospitals with mixed medical/surgical/cardiac PICU.
METHODS: Parents of patients unexpectedly admitted to the PICU.
METHODS: None.
RESULTS: 265 parents of 188 children were enrolled of whom 49 parents (18%) met ASD qualification and 108 (41%) parents developed ASD symptoms as determined by the ASDS-5 scale. Risk factors making parents likely to meet ASD qualification include parents from area served by Penn State (p < 0.001), prior psychiatric illness (p < 0.01), and female gender (p < 0.05), while graduating college was protective (p < 0.05). In the multivariate analysis, parents from area served by Penn State (OR 3.00 (1.49-6.05) p < 0.01) and parents with prior psychiatric illness (OR 2.16 (1.03-4.52) p < 0.05) were associated with ASD qualification. Parents who graduated college or had prior medical problems were not significant.Risk factors making parents more likely to develop ASD symptoms (significant symptoms that do not meet ASD qualification) include patients with higher PRISM-III scores (p < 0.01), patients receiving cardiovascular support (p < 0.05), parents with a history of prior physical/sexual abuse (p < 0.01), parental involvement in the past with a major disaster/accident (p < 0.01), a family member admitted to an ICU in the past (p < 0.05) and preexisting parental psychiatric/medical disorders (p < 0.001). In a multivariate analysis, prior parental psychiatric disorder (OR 4.11 (1.80-6.42) p < 0.001), history of parental abuse (OR 3.11 (1.14-5.08) p < 0.05), and parental prior medical problem (OR 2.03 (1.01-3.05) p < 0.05) were associated with the development of ASD symptoms. However, PRISM-III score and prior involvement in major disaster were not significant.
CONCLUSIONS: A combination of psychosocial parental risk factors and patient factors were associated with acute stress in parents. Further studies evaluating targeted hospital interventions towards parents most at-risk are needed.

BACKGROUND: Significant improvements in under-five mortality in Malawi have been demonstrated over the past thirty years; however, Malawian healthcare remains with gaps in availability and access to quality pediatric critical care nursing training and education. To improve expertise of pediatric critical care nurses in Malawi, Kamuzu University of Health Sciences (KUHeS), Queen Elizabeth Central Hospital (QECH), and Mercy James Center (MJC) entered a partnership with Seed Global Health, a US non-governmental organization. A needs assessment was conducted to understand the training needs of nurses currently working in pediatric critical care and in preparation for the development of a specialized Master\'s in Child Health pathway in Pediatric Critical Care (PCC) Nursing at KUHeS.
METHODS: The needs assessment was completed using a survey questionnaire formatted using an ABCDE (Airway, Breathing, Circulation, Disability, and Exposure) framework. The questionnaire had Likert scale and yes/no questions. Data was manually entered into excel and was analyzed using descriptive statistics.
RESULTS: One hundred and fifty-three nurses at QECH and MJC responded to the survey. Most nurses were between the ages of 25 and 35 years (N = 98, 64%), female (N = 105, 69%), and held either a Bachelors (N = 72, 47%) or diploma (N = 70, 46%) in nursing. Nurses had high rates of confidence in certain skills: airway management (N = 120, 99%), breathing assessment & management (N = 153, 100%). However, nurses demonstrated little to no confidence in areas such as: mechanical ventilation (N = 68, 44%), ECG evaluation (N = 74, 48%), and arterial blood gas collection & interpretation (N = 49, 32%).
CONCLUSIONS: It is important to identify priority areas for training and skills development to address in the PCC master\'s within the child health pathway at KUHeS. Ideally this partnership will produce practice-ready PCC nurses and will establish a recognized PCC nursing workforce in Malawi.
