A qualitative study was carried out with five professionals in a pediatric intensive care unit in 2022. Semi-structured interviews were used to find out how they felt about patients from their own culture, and about the role of their mother tongue in hospital care. Caregivers find it difficult to bring their own culture to the fore when caring for their patients. A description of the obstacles they encounter, as well as the advantages, is included.

Pediatric pulmonary critical care literature has continued to grow in recent years. Our aim in this review is to narrowly focus on publications providing clinically-relevant advances in pediatric pulmonary critical care in 2023.

OBJECTIVE: To determine whether implementation of an education-based intervention can sustainably improve upstream and downstream outcomes in intubated patients in a pediatric intensive care unit (PICU) in a low-resource country.
METHODS: Quality improvement study comparing airway-related morbidity in two previously studied patient cohorts pre-intervention (Epoch 1) and immediately post-intervention (Epoch 2) with a third cohort thirty-six months post-intervention (Epoch 3).
METHODS: PICU of the largest public children\'s hospital in El Salvador.
METHODS: 147 patients under 18 years requiring intubation and mechanical ventilation (MV) met inclusion criteria in the long-term follow-up period and were consecutively sampled without exclusion (Epoch 3) (compared to 98 previously studied patients in the short-term follow-up period (Epoch 2)).
METHODS: A low-cost, education-based intervention to close knowledge gaps, improve communication among PICU doctors, nurses, and respiratory therapists, and optimize patient outcomes.
RESULTS: The primary outcome measure was change in unplanned extubation (UE) between Epochs 2 and 3. Other outcomes included use of cuffed endotracheal tubes (ETT), rate of elective ETT change and days of MV. The 17 % decrease in UE previously reported for Epoch 2 was sustained in Epoch 3. There was a statistically significant increase in use of cuffed ETT from 35.7 % in Epoch 2-55.1 % in Epoch 3 (p = 0.003, z-score -2.99). There was also a statistically significant mean difference in rate of elective ETT change per 100 MV days from Epoch 2 to Epoch 3 of 1.7 (p = 0.007; 95 % CI 0.15-0.84). There was no change in MV days from Epoch 2 to Epoch 3 (p-value 0.764; 95 % CI -1.48-2.02). Beyond these quantifiable results, many unanticipated practice changes were observed three years after the initial intervention.
CONCLUSIONS: Sustained improvement in upstream and downstream outcomes (UE, cuffed ETT use, elective ETT change) for intubated patients in a low-resource PICU were observed three years after a low-cost, low-touch, education-based intervention.

BACKGROUND: High-flow nasal cannula therapy has garnered significant interest for managing pathologies affecting infants\' airways, particularly for humidifying areas inaccessible to local treatments. This therapy promotes mucosal healing during the postoperative period. However, further data are needed to optimize the use of these devices. In vivo measurement of pediatric airway humidification presents a challenge; thus, this study aimed to investigate the airflow dynamics and humidification effects of high-flow nasal cannulas on an infant\'s airway using computational fluid dynamics.
METHODS: Two detailed models of an infant\'s upper airway were reconstructed from CT scans, with high-flow nasal cannula devices inserted at the nasal inlets. The airflow was analyzed, and wall humidification was modeled using a film-fluid approach.
RESULTS: Air velocities and pressure were very high at the airway inlet but decreased rapidly towards the nasopharynx. Maximum relative humidity-close to 100%-was achieved in the nasopharynx. Fluid film development along the airway was heterogeneous, with condensation primarily occurring in the nasal vestibule and larynx.
CONCLUSIONS: This study provides comprehensive models of airway humidification, which pave the way for future studies to assess the impact of surgical interventions on humidification and drug deposition directly at operative sites, such as the nasopharynx or larynx, in infants.

Though pediatric cardiomyopathy is rare in children, there is significant associated morbidity and mortality. Etiology varies from inborn errors of metabolism to familial genetic mutations and myocyte injury. Major classes include dilated, hypertrophic, restrictive, and non-compaction. Diagnosis generally involves a combination of clinical history and echocardiography. The use of cross-sectional imaging is gaining popularity. Management varies between subtype and may involve a combination of medical and surgical interventions depending on clinical status.

BACKGROUND: Parents of children who die in the pediatric intensive care unit (PICU) carry memories of their child\'s suffering throughout a lifelong grieving experience. Given their prolonged time at the bedside, PICU nurses are poised to attend to dying children\'s suffering.
OBJECTIVE: We aimed to explore how PICU nurses identify, assess, and attend to EOL suffering.
METHODS: Interpretive descriptive qualitative study with thematic analysis of virtual focus groups from a geographically diverse sample of PICU nurses.
RESULTS: Nurses participated in five focus groups (N = 19). Most identified as White (89%) females (95%) with a range of 1-24 years of PICU experience and involvement in >10 EOL care cases (89%). Nurses described approaches to suffering within five themes: 1) Identifying and easing perceptible elements; 2) Recognizing and responding to subtleties moment-to-moment; 3) Acclimating to family interdependence; 4) Synchronizing nurse in-the-room insight with systemic complexity; and 5) Accounting for ambiguity. Nurses detailed elements of suffering they could \"fix\" with straightforward, external interventions (e.g., pain medication). More complex tasks like optimizing care within familial and interprofessional team relationships while navigating psychosocial responses from children and families challenged nurses. Nurses attempted to minimize EOL suffering amidst ambiguity and complexity using internal processes including managing the environment and titrating moment-to-moment care.
CONCLUSIONS: While physical suffering may be remedied with direct nursing care, holistically attending to EOL suffering in the PICU requires both bolstering external processes and strengthening PICU nurses\' internal resources. Improving psychosocial training and optimizing interprofessional care systems could better support dying children and their families.

BACKGROUND: The ictal-interictal continuum (IIC) consists of several electroencephalogram (EEG) patterns that are common in critically ill adults. Studies focused on the IIC are limited in critically ill children and have focused primarily on associations with electrographic seizures (ESs). We report the incidence of the IIC in the pediatric intensive care unit (PICU). We then compare IIC patterns to rhythmic and periodic patterns (RPP) not meeting IIC criteria looking for associations with acute cerebral abnormalities, ES, and in-hospital mortality.
METHODS: This was a retrospective review of prospectively collected data for patients admitted to the PICU at Children\'s National Hospital from July 2021 to January 2023 with continuous EEG. We excluded patients with known epilepsy and cerebral injury prior to presentation. All patients were screened for RPP. The American Clinical Neurophysiology Society standardized Critical Care EEG terminology for the IIC was applied to each RPP. Associations between IIC and RPP not meeting IIC criteria, with clinical and EEG variables, were calculated using odds ratios (ORs).
RESULTS: Of 201 patients, 21% (42/201) had RPP and 12% (24/201) met IIC criteria. Among patients with an IIC pattern, the median age was 3.4 years (interquartile range (IQR) 0.6-12 years). Sixty-seven percent (16/24) of patients met a single IIC criterion, whereas the remainder met two criteria. ESs were identified in 83% (20/24) of patients and cerebral injury was identified in 96% (23/24) of patients with IIC patterns. When comparing patients with IIC patterns with those with RPP not qualifying as an IIC pattern, both patterns were associated with acute cerebral abnormalities (IIC OR 26 [95% confidence interval {CI} 3.4-197], p = 0.0016 vs. RPP OR 3.5 [95% CI 1.1-11], p = 0.03), however, only the IIC was associated with ES (OR 121 [95% CI 33-451], p < 0.0001) versus RPP (OR 1.3 [0.4-5], p = 0.7).
CONCLUSIONS: Rhythmic and periodic patterns and subsequently the IIC are commonly seen in the PICU and carry a high association with cerebral injury. Additionally, the IIC, seen in more than 10% of critically ill children, is associated with ES. The independent impact of RPP and IIC patterns on secondary brain injury and need for treatment of these patterns independent of ES requires further study.

OBJECTIVE: To describe the high-flow nasal cannula (HFNC) indications in the Spanish pediatric critical care units (PICUs).
METHODS: Descriptive cross-sectional observational study.
METHODS: Electronic survey among members of the Spanish Society of Pediatric Intensive Care (SECIP). It was sent weekly from April 10, 2023, to May 21, 2023.
METHODS: All SECIP members.
METHODS: None.
METHODS: The questions focused on workplace, years of experience, use or non-use of HFNC, justification and expectations regarding its application, starting point within each center, clinical criteria for indication, existence of clinical guidelines, evaluation during its use, and criteria and mode of withdrawal.
RESULTS: Two hundred and two participants, 176 were from Spain. Of these, 87/176 had over ten years of experience. One hundred sixty two use HFNC and 66/162 have HFNC clinical guidelines. Acute bronchiolitis (138/162) and respiratory assistance after extubation (106/56) are the two main indications. For 62/162 HFNC may reduce therapeutic escalation. Neuromuscular diseases (105/162) and anatomical airway diseases (135/162) are the two main contraindications. The reasons to do not use HFNC were the absence of evidence about it effectiveness (8/14) and its inadequate cost/effectiveness balance (8/14).
CONCLUSIONS: A majority of Spanish pediatric intensivists use HFNC. Its application and withdrawal appears to be primarily based on clinical experience. Besides, those who use HFNC are aware of its limitations and the lack of evidence in some cases. It is necessary to develop single-center and multicenter studies to elucidate the effectiveness of this therapy in the context of critically ill children.

OBJECTIVE: We hypothesized that collaborative intervention to improve weighted pediatric readiness score (WPRS) will be associated with decreased pediatric intensive care (PICU) mortality, PICU and hospital length of stay.
METHODS: This study analyzes the transfer of acutely ill and injured patients from general emergency departments (GEDs) to our institution. The intervention involved customized assessment reports focusing on team performance and systems improvement for pediatric readiness, sharing best practices and clinical resources, designation of a nurse PECC at each GED and ongoing interactions at 2 and 4 months. Data was collected from charts before and after the intervention, focusing on patients transferred to our pediatric emergency department (ED) or directly admitted to our PICU from the GEDs. Clinical outcomes such as PICU length of stay (LOS), hospital LOS, and PICU mortality were assessed. Descriptive statistics were used for demographics, and various statistical tests were employed to analyze the data. Bivariate analyses and multivariable models were utilized to examine patient outcomes and the association between the intervention and outcomes.
RESULTS: There were 278 patients in the pre-intervention period and 314 patients in the post-intervention period. Multivariable analyses revealed a significant association between the change in WPRS and decreased PICU LOS (β=-0.05 [95% CI: -0.09, -0.01), p=0.023), and hospital LOS (β=-0.12 [95% CI: -0.21, -0.04], p=0.004), but showed no association between the intervention and other patient outcomes.
CONCLUSIONS: In this cohort, improving pediatric readiness scores in GEDs was associated with significant improvements in PICU and hospital length of stay. Future initiatives should focus on disseminating pediatric readiness efforts to improve outcomes of critically ill children nationally.
UNASSIGNED: Improving pediatric readiness scores in general emergency departments is associated with improved downstream clinical outcomes demonstrated by reduced PICU and hospital length of stay.

UNASSIGNED: Gastrointestinal bleeding (GI) is a prevalent condition among pediatric patients, with a reported incidence of 6.4%, often severe enough to require admission to the pediatric intensive care unit (PICU). There are multiple therapies utilized in the management of GI bleeding in pediatrics, among which continuous intravenous (IV) infusion of omeprazole is used off-label without standard pediatric dosing recommendations. Reviewing the current literature reveals a lack of studies assessing the efficacy, safety, and appropriate dosing regimen of continuous omeprazole infusion in children with GI bleeding. This study aimed to evaluate the efficacy and safety of continuous IV omeprazole infusion in comparison to other therapeutic modalities in children.
UNASSIGNED: This study is a single-center, retrospective chart review of children admitted to the PICU at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia. The treatment group included pediatric patients with GI bleeding and receiving omeprazole IV continuous infusion over ≥24 h while the control group included pediatric patients with GI bleeding managed using other therapies. Primary outcomes were the efficacy of omeprazole continuous infusion in stopping GI bleeding, and PICU length of stay (LOS). Secondary outcomes included instances of rebleeding post- therapy discontinuation, transfusion requirements, and the safety of omeprazole continuous infusion.
UNASSIGNED: The study included 81 critically ill pediatric patients, 22 of whom received continuous infusion omeprazole while 59 received other therapies. The results indicated that patients in the control group had a significantly shorter PICU LOS (8 vs. 18.5 days, p < 0.001) and bleeding episode (4 vs. 10.5 days, p < 0.001) than those in the treatment group. However, no significant differences were observed between the two groups regarding secondary outcomes. The treatment group had a significantly lower all-cause mortality rate during hospitalization compared to the control group (16 patients [72.7%] vs. 56 patients [94.9%], respectively, p = 0.005).
UNASSIGNED: Empirical use of omeprazole continuous intravenous infusion in children with GI bleeding was not favorable in terms of shortening PICU LOS and duration of GI bleeding. Our study results provide evidence supporting the safety and tolerability of omeprazole continuous infusion. Additional larger studies are necessary to determine the implication of such results.
