Respiratory Dysfunction Criteria in Critically Ill Children: The PODIUM Consensus Conference

Comparison of sleep quality between outpatient and hospitalized children with respiratory tract dysfunction

OBJECTIVES

The main objective of the study to compare the effect of hospitalized and outpatient settings on quality of sleep in children with respiratory tract dysfunction.

METHODOLOGY

A descriptive correlational study was carried out at Dhi-Qar Health Directorate pediatric hospitals. The period of the study was from the November 19, 2023 to March 10, 2024. Purposive sample (non-probability) of 250 children (male and female). A total of (125) children were chosen from the children whose admitted to the hospitals, and a total of (125) children were chosen from the outpatient settings. The study instrument consisted of three parts: the sociodemographic sheet, clinical diagnosis sheet, and sleep quality scale. The questionnaire was modified according to experts' recommendation to use it for children with respiratory tract dysfunction. The questionnaire was evaluated by a panel of 15 experts from diverse medical and nursing professions. Both descriptive and inferential statistics were used to analyze the data.

RESULTS

The study findings that effect outpatient settings have more effect from hospitalized settings on quality of sleep in children with respiratory tract dysfunction (M ± SD = 1.322 ± 0.1522).

CONCLUSION

A study showed that the quality of sleep in children with respiratory tract dysfunction was generally average, whether in hospitalized or outpatient settings, outpatient settings had greater difficulties falling asleep and waking than children in hospitalized.

Stratifying Severity of Acute Respiratory Failure Severity in Cyanotic Congenital Heart Disease

Hypoxemia is used to stratify severity in acute respiratory failure (ARF) but is less useful in cyanotic congenital heart disease (CCHD) due to an inability to differentiate hypoxemia from lung injury versus cardiac shunting. Therefore, we aimed to determine whether variables related to respiratory mechanics were associated with outcomes to assist in stratifying ARF severity in pediatric CCHD. We performed a retrospective cohort study from a single cardiac intensive care unit enrolling children with CCHD with ARF requiring mechanical ventilation between 2011 and 2019. Time-averaged ventilator settings and oxygenation data in the first 24 h of ARF were screened for association with the primary outcome of 28-day mortality. Of 344 eligible patients, peak inspiratory pressure (PIP) and driving pressure (ΔP) were selected as candidate variables to stratify ARF severity. PIP (OR 1.10, 95% CI 1.02-1.19) and ΔP (1.11, 95% CI 1.01-1.24) were associated with higher mortality and fewer ventilator-free days (VFDs) at 28 days after adjusting for age, severity of cardiac history, and FiO₂. A three-level (mild, moderate, severe) severity stratification was established for both PIP (≤ 20, 21-29, ≥ 30) and ΔP (≤ 16, 17-24, ≥ 25), showing increasing mortality (both P < 0.01), decreasing VFDs and increasing ventilator days in survivors (all P < 0.05) across increasing pressures. Overall, we found that higher PIP and ΔP were associated with mortality and duration of ventilation across a three-level severity stratification system in pediatric CCHD with ARF, providing a practical method to prognosticate in subjects with multifactorial etiologies for hypoxemia.

Definition, Incidence, and Epidemiology of Pediatric Acute Respiratory Distress Syndrome: From the Second Pediatric Acute Lung Injury Consensus Conference

OBJECTIVES

In 2015, the Pediatric Acute Lung Injury Consensus Conference (PALICC) provided the first pediatric-specific definitions for acute respiratory distress syndrome (pediatric acute respiratory distress syndrome [PARDS]). These definitions have since been operationalized in cohort and interventional PARDS studies. As substantial data have accrued since 2015, we have an opportunity to assess the construct validity and utility of the initial PALICC definitions. Therefore, the Second PALICC (PALICC-2) brought together multiple PARDS experts and aimed to identify and summarize relevant evidence related to the definition and epidemiology of PARDS and create modifications to the definition of PARDS.

DATA SOURCES

MEDLINE (Ovid), Embase (Elsevier), and CINAHL Complete (EBSCOhost).

STUDY SELECTION

We included studies of subjects with PARDS, or at risk for PARDS, excluding studies pertaining primarily to adults except as specified for identifying age-specific cutoffs.

DATA EXTRACTION

Title/abstract review, full-text review, and data extraction using a standardized data collection form.

DATA SYNTHESIS

The Grading of Recommendations Assessment, Development, and Evaluation approach was used to identify and summarize evidence and develop recommendations. A total of 97 studies were identified for full-text extraction addressing distinct aspects of the PARDS definition, including age, timing, imaging, oxygenation, modes of respiratory support, and specific coexisting conditions. Data were assessed in a Patient/Intervention/Comparator/Outcome format when possible, and formally summarized for effect size, risk, benefit, feasibility of implementation, and equity. A total of 17 consensus-based definition statements were made that update the definition of PARDS, as well as the related diagnoses of "Possible PARDS" and "At-Risk for PARDS." These statements are presented alongside a summary of the relevant epidemiology.

CONCLUSIONS

We present updated, data-informed consensus statements on the definition for PARDS and the related diagnoses of "Possible PARDS" and "At-Risk for PARDS."
