Brief summary

Across 18 randomized studies with 4,094 children aged 24 months or younger with bronchiolitis, high-flow nasal cannula reduced treatment failure versus low-flow oxygen but did not significantly reduce mechanical ventilation or outperform CPAP.

What NurseJet pulled from the source

This systematic review and meta-analysis included 18 randomized studies and 4,094 children aged 24 months or younger with bronchiolitis. Trials compared high-flow nasal cannula with low-flow nasal cannula or continuous positive airway pressure. High-flow therapy did not significantly reduce mechanical ventilation versus low-flow oxygen (RR 0.69, 95% CI 0.33 to 1.44) or CPAP (RR 0.90, 95% CI 0.65 to 1.24). Compared with low-flow oxygen, it reduced treatment failure (RR 0.44, 95% CI 0.23 to 0.87) and shortened pediatric ICU stay by 0.40 days (95% CI 0.02 to 0.78 days shorter). Compared with CPAP, treatment failure and PICU stay did not differ significantly. The review supports high-flow therapy as an escalation option from low-flow oxygen, but it does not show that high-flow prevents intubation or performs better than CPAP across the studied outcomes.

Why this matters for nurses

Pediatric nurses frequently monitor infants receiving escalating oxygen support and identify signs of treatment failure. This review matters because it separates a lower failure rate versus low-flow oxygen from the absence of evidence that high-flow reduces mechanical ventilation or outperforms CPAP.

Bedside takeaway

Worth knowing that high-flow nasal cannula reduced treatment failure versus low-flow oxygen in bronchiolitis, but did not significantly reduce mechanical ventilation or outperform CPAP.

Key takeaways

Eighteen randomized studies included 4,094 children aged 24 months or younger with bronchiolitis.
High-flow nasal cannula reduced treatment failure versus low-flow oxygen, with a pooled risk ratio of 0.44.
High-flow therapy did not significantly reduce mechanical ventilation compared with either low-flow oxygen or CPAP.
Treatment failure and PICU length of stay did not differ significantly between high-flow therapy and CPAP.

Practice implications

For pediatric teams, the findings support following locally approved criteria for starting, monitoring, and escalating high-flow therapy rather than assuming it prevents intubation. Device selection, settings, reassessment, and movement to CPAP or invasive support remain clinician-directed and protocol-specific.

Limitations & cautions

The review pooled studies with different respiratory-support comparisons, and the abstract does not provide certainty ratings, detailed risk-of-bias findings, or standardized definitions of treatment failure. It also does not identify which patient subgroups or high-flow protocols are most likely to benefit.

Western journal of nursing research (PubMed)Oct 15, 2026Systematic Review

A systematic review and meta-analysis of 38 studies including 19,033 patients identified clinical severity scales—specifically Modified Fisher grade and Fisher grade—and hemodynamic status as the strongest predictors of cerebral vasospasm following subarachnoid hemorrhage.

Emergency ICUAI summaryReview source

Systematic ReviewResearchQuality ImprovementAI summary · original source linked below

Cerebral vasospasm is a severe complication of aneurysmal subarachnoid hemorrhage (SAH) that frequently precipitates delayed cerebral ischemia and increases patient mortality. To clarify clinical predictors and inform intensive care nursing assessments, investigators conducted a systematic review and meta-analysis across eight databases through August 2024, evaluating study quality with the Joanna Briggs Institute checklist and Risk of Bias 2.0 tool. Across 38 included studies (27 in the meta-analysis) encompassing 19,033 patients, clinical severity metrics showed the strongest association with cerebral vasospasm: Modified Fisher grade (odds ratio [OR] 2.88; 95% CI, 2.04–4.07), Fisher grade (OR 2.27; 95% CI, 1.91–2.69), and hemodynamic status (OR 2.56; 95% CI, 1.17–5.59). Aneurysm-related characteristics and comorbid conditions were also linked to increased vasospasm risk, whereas clinical biomarkers and inflammatory markers demonstrated comparatively smaller effect sizes.

Key takeaways

Systematic review and meta-analysis synthesized 38 studies (27 in meta-analysis) encompassing 19,033 patients after subarachnoid hemorrhage.
Radiographic and clinical severity scales showed the strongest association with cerebral vasospasm: Modified Fisher grade (OR 2.88; 95% CI, 2.04–4.07) and Fisher grade (OR 2.27; 95% CI, 1.91–2.69).
Hemodynamic instability was strongly associated with vasospasm risk (OR 2.56; 95% CI, 1.17–5.59).
Aneurysm features and comorbidities also increased risk, while clinical biomarkers and inflammatory markers demonstrated smaller effect sizes.

Why this matters on shift

Neurocritical care nurses are the first line of defense in detecting subtle neurological deterioration and hemodynamic shifts in patients hospitalized for subarachnoid hemorrhage. Understanding that initial Fisher grade and hemodynamic status carry the highest statistical odds for vasospasm reinforces rigorous serial neurological scoring and strict blood pressure monitoring during the peak vasospasm window.

Bedside takeaway

In a meta-analysis of 19,033 SAH patients, Modified Fisher grade (OR 2.88), Fisher grade (OR 2.27), and hemodynamic status (OR 2.56) were the strongest predictors of cerebral vasospasm.

Nursing implications

Identify admission Fisher or Modified Fisher scores during shift handoff, maintain strict hemodynamic parameters per provider orders, and immediately escalate focal neurological deficits, altered sensorium, or transcranial Doppler velocity increases.

Limitations & cautions

Synthesized observational studies with heterogeneous definitions and reporting standards; meta-analysis reflects statistical associations rather than prospective causal prediction models; abstract does not detail specific individual biomarker cutoff values.

Natriuresis-guided loop diuretic titration uses spot urinary sodium measurements to tailor decongestive therapy in acute heart failure (AHF). In this sex-specific analysis of the randomized PUSH-AHF trial, investigators evaluated 310 patients (45% women) assigned to natriuresis-guided therapy versus standard of care. In men, natriuresis-guided therapy produced significantly greater mean 24-hour total natriuresis compared with standard care (443 vs 354 mmol, p = 0.004), whereas women showed no significant difference between treatment arms (357 vs 336 mmol, p = 0.533; adjusted p-interaction = 0.276). Notably, the median 24-hour natriuretic response per milligram of loop diuretic (bumetanide equivalents) was significantly lower in women receiving natriuresis-guided therapy than standard care (23 vs 52 mmol/mg, p = 0.001), while no difference was observed in men (38 vs 45 mmol/mg, p = 0.337; adjusted p-interaction = 0.009). Clinically, natriuresis guidance was associated with a 49% lower risk of 180-day all-cause mortality or HF rehospitalization in men (adjusted HR 0.51; 95% CI, 0.30–0.86; p = 0.011), but showed no benefit in women (adjusted HR 1.40; 95% CI, 0.67–2.91; p = 0.368; adjusted p-interaction = 0.026).

Key takeaways

Sex-specific analysis of the PUSH-AHF randomized trial evaluated 310 patients (45% women) with acute heart failure.
In men, natriuresis-guided therapy increased 24-hour urinary sodium excretion (443 vs 354 mmol, p = 0.004) and reduced 180-day mortality/rehospitalization by 49% (adjusted HR 0.51, p = 0.011).
In women, natriuresis guidance did not increase total natriuresis (357 vs 336 mmol, p = 0.533) or improve 180-day clinical outcomes (adjusted HR 1.40, p = 0.368; p-interaction = 0.026).
Women in the guided arm exhibited a blunted natriuretic response per milligram of loop diuretic (23 vs 52 mmol/mg bumetanide, p = 0.001).

Why this matters on shift

Cardiology and telemetry nurses frequently manage intensive loop diuretic infusions and collect spot urinary sodium samples during acute decompensated heart failure admissions. These findings demonstrate that diuretic responsiveness and natriuresis-guided protocols may operate differently by biological sex, warning clinicians that intensifying diuretic doses based solely on spot sodium targets may not yield uniform decongestive or prognostic benefits across all patient groups.

Bedside takeaway

In the PUSH-AHF trial (310 patients), natriuresis-guided diuretic therapy reduced 180-day mortality/readmission in men (aHR 0.51) but showed no benefit in women (aHR 1.40; p-interaction=0.026).

Nursing implications

Collect urine samples for spot sodium strictly at ordered intervals during acute decongestion, maintain accurate intake/output records, monitor serum electrolytes and renal function closely during diuretic uptitration, and recognize that blunted urinary sodium output in female patients may reflect altered pharmacodynamics rather than simple noncompliance with fluid restrictions.

Limitations & cautions

Post-hoc subgroup analysis of a randomized trial with limited sample size (n = 310, including 139 women); findings are hypothesis-generating and require prospective validation in sex-stratified clinical trials before modifying clinical guidelines.

Pediatrics (PubMed)Oct 1, 2026Clinical Guideline

The American Academy of Pediatrics updated its clinical practice guideline for diagnosing and managing urinary tract infections in infants and children aged 8 days to 5 years with low medical complexity.

Peds EmergencyAI summaryReview source

Clinical GuidelineGuidelineQuality ImprovementPatient EducationAI summary · original source linked below

Urinary tract infections (UTIs) occur in approximately 7% of febrile infants and represent one of the most common bacterial infections in pediatric practice. Replacing the 2011 guidance, the American Academy of Pediatrics issued an updated clinical practice guideline with three companion technical reports for children 8 days to 5 years of age with low medical complexity. Developed using the GRADE framework with evidence-to-decision panels, the update provides eight Key Action Statements (two strong and six conditional recommendations ranging from low to very low certainty of evidence) and four Good Practice Statements. Core guidance spans the diagnostic evaluation of suspected UTI, targeted antimicrobial selection and treatment duration, indications for renal and bladder ultrasound and voiding cystourethrography, prevention of structural sequelae including vesicoureteral reflux, and structured screening and treatment for bowel and bladder dysfunction.

Key takeaways

AAP updated its pediatric UTI guideline for children aged 8 days to 5 years with low medical complexity.
Formulates 8 Key Action Statements (2 strong, 6 conditional) and 4 Good Practice Statements using GRADE methodology.
Refines diagnostic sampling criteria, acute antibiotic selection, and targeted duration to minimize antimicrobial resistance.
Updates indications for renal imaging, vesicoureteral reflux evaluation, and systematic management of bowel and bladder dysfunction.

Why this matters on shift

Pediatric and emergency nurses are central to identifying febrile infants at risk for UTI, executing proper catheterized or clean-catch urine specimen collection, and guiding families through antibiotic completion and scheduled follow-up imaging. Standardizing diagnostic thresholds prevents both delayed pyelonephritis treatment and unnecessary antibiotic exposure in young children.

Bedside takeaway

AAP updated its pediatric UTI guideline for children 8 days to 5 years, delivering 8 Key Action Statements on diagnostic sampling, targeted antibiotic therapy, imaging indications, and bowel-bladder dysfunction.

Nursing implications

Collect clean catheterized urine specimens rather than bag samples for culture in non-toilet-trained febrile infants, reinforce completing prescribed antibiotic courses with parents, and assess older toddlers for withholding and bowel/bladder dysfunction during discharge education.

Limitations & cautions

Guideline applies specifically to children with low medical complexity and excludes those with neurogenic bladder, known high-grade anatomical urological anomalies, or immunodeficiency; evidence certainty for several recommendations remains low to very low.
