Brief summary

A Cochrane review found that using cord or placental blood for admission tests likely reduced retinopathy of prematurity requiring treatment and may have reduced severe intraventricular hemorrhage in very preterm infants.

What NurseJet pulled from the source

Five randomized trials included 365 preterm infants whose mean gestational age was under 29 weeks. Compared with sampling only from the infant, cord or placental admission sampling likely reduced treated retinopathy of prematurity and may have reduced severe intraventricular hemorrhage. Evidence for mortality and for blood-return devices or strict sampling protocols was very uncertain.

Why this matters for nurses

Neonatal nurses coordinate frequent laboratory testing while protecting a very small circulating blood volume. This review identifies cord or placental admission sampling as a promising conservation strategy while showing that evidence for other approaches remains limited.

Bedside takeaway

Cord or placental blood for admission tests may conserve infant blood and reduce selected preterm morbidities, but evidence for other strategies remains uncertain.

How This Applies in Practice

Use this when: Preparing admission laboratory testing for a very preterm infant in a neonatal unit with an approved placental or cord-blood sampling pathway.

On your shift

Confirm which ordered admission tests are validated for cord or placental blood and follow the unit collection protocol.
Document specimen source and monitor specimen adequacy, repeat draws, and subsequent cumulative blood sampling.
Escalate inadequate specimens or urgent testing needs without delaying clinically necessary infant sampling.

Keep in mind: The evidence comes from five small trials and does not validate every blood-conservation device or protocol. Follow neonatal policy and provider orders.

Key takeaways

The review included five randomized trials with 365 preterm infants; mean gestational age was under 29 weeks in every study.
Cord or placental admission sampling likely reduced retinopathy of prematurity requiring treatment compared with sampling only from the infant.
The same strategy may reduce severe intraventricular hemorrhage, but that evidence was low certainty.
Evidence for blood-return devices, strict sampling protocols, mortality, and long-term neurodevelopment was very uncertain or unavailable.

Practice implications

Within an approved neonatal pathway, coordinate which admission tests can use cord or placental blood, label and handle specimens correctly, and track subsequent sampling volume. Do not delay clinically necessary testing or improvise blood-return methods outside protocol.

Limitations & cautions

Only five small trials were included, and the different conservation strategies could not be treated as one intervention. Mortality and most major morbidity estimates were uncertain, and no study reported the specified long-term neurodevelopmental outcomes.

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.

A phase 3 double-blind randomized clinical trial of 271 pediatric and young adult sickle cell patients halted early for futility found that intravenous arginine did not shorten time to pain crisis resolution or decrease total parenteral opioid requirements compared with placebo.

Emergency PedsAI summaryReview source

Vaso-occlusive pain episodes represent the primary driver of emergency department visits and acute inpatient admissions in sickle cell disease (SCD). Patients frequently exhibit acute arginine deficiency during pain crises, and earlier phase 2 single-center trials suggested supplemental arginine might reduce hospital stay and opioid requirements. The multicenter phase 3 STArT trial, conducted across 10 US children's hospitals, evaluated whether intravenous arginine (200 mg/kg loading dose followed by 100 mg/kg every 8 hours) improved clinical outcomes compared to saline placebo in patients aged 3 to 21 years presenting to the ED with SCD pain requiring parenteral opioids. Among 274 randomized patients (271 received study drug; mean age 14.3 years; 51% male; 92% Black), the trial was halted early for futility. Time to crisis resolution—defined as time from initial infusion to final parenteral opioid dose—did not differ between arginine and placebo (median 60.8 hours [IQR 34.8–109.0] vs 65.8 hours [IQR 31.1–111.1]; absolute difference 7.2 hours; 95% CI -21.6 to 35.9). Secondary endpoints including cumulative parenteral opioid consumption, numeric pain scores, and safety profiles showed no significant differences.

Key takeaways

Multicenter double-blind phase 3 trial across 10 US children's hospitals enrolled 271 patients aged 3 to 21 years with severe sickle cell pain episodes.
Trial was terminated early by the data and safety monitoring board due to clinical futility.
Intravenous arginine did not shorten median time to pain crisis resolution compared with placebo (60.8 vs 65.8 hours; absolute difference 7.2 hours).
Arginine did not decrease cumulative parenteral opioid consumption or improve patient-reported pain intensity scores.

Why this matters on shift

Emergency and pediatric nurses are on the front lines of administering rapid parenteral analgesia and titrating scheduled opioids during severe sickle cell vaso-occlusive crises. Demonstrating that IV arginine confers no opioid-sparing or crisis-shortening benefit clarifies that nurses should continue prioritizing prompt evidence-based opioid titration, aggressive hydration, and individualized pain protocols.

Bedside takeaway

In a 271-patient multicenter pediatric trial halted early for futility, IV arginine did not shorten time to sickle cell pain crisis resolution (median 60.8 vs 65.8 hrs) or reduce total opioid requirements compared to placebo.

Nursing implications

Do not delay or alter standard guideline-directed parenteral opioid delivery for sickle cell pain crises in anticipation of arginine therapy, and maintain rigorous pain assessments and adverse-effect monitoring on shift.

Limitations & cautions

Trial halted prematurely for futility; enrolled cohort limited to pediatric and transitional young adult patients aged 3 to 21 years; findings may not generalize to older adult sickle cell populations.

Critical care medicine (PubMed)Oct 1, 2026Systematic Review

A systematic review and meta-analysis of 16 cohorts encompassing over 2.6 million pediatric encounters found that the Phoenix Sepsis Criteria significantly outmatched the 2005 IPSCC criteria for predicting in-hospital mortality (AUC 0.81 vs 0.71), but demonstrated low specificity in ICU cohorts (0.48).

In 2024, the Society of Critical Care Medicine released the Phoenix Sepsis Criteria (PSC) to replace the 2005 systemic inflammatory response syndrome (SIRS)-based pediatric sepsis consensus definitions. This systematic review and meta-analysis evaluated the prognostic accuracy of the PSC for in-hospital mortality across hospital settings and compared it directly with the 2005 International Pediatric Sepsis Consensus Conference (IPSCC) definitions. Analyzing 15 studies encompassing 16 distinct cohorts and 2,601,038 pediatric patient encounters, the PSC demonstrated a pooled sensitivity of 0.77 (95% CI 0.67–0.85), a specificity of 0.73 (95% CI 0.51–0.87), a diagnostic odds ratio of 9.2 (95% CI 5.1–16.8), and an overall area under the receiver operating characteristic curve (AUC) of 0.81 (95% CI 0.75–0.84). The PSC significantly outperformed the 2005 IPSCC criteria (AUC 0.71; difference 0.10; 95% CI 0.04–0.19). Subgroup analysis revealed that while PSC specificity was high in emergency departments (0.99), it dropped substantially in pediatric intensive care units (0.48), underscoring that the tool functions primarily for mortality risk stratification rather than early frontline triage screening.

Key takeaways

Meta-analysis synthesized 15 diagnostic studies and 16 cohorts covering 2,601,038 pediatric hospital encounters.
Phoenix Sepsis Criteria demonstrated an overall pooled AUC of 0.81 for predicting in-hospital mortality, significantly superior to 2005 IPSCC (AUC 0.71).
Diagnostic specificity varied dramatically by clinical setting, reaching 0.99 in emergency departments but dropping to 0.48 in intensive care units.
Authors emphasize that the Phoenix criteria serve to stratify mortality risk once organ dysfunction develops, rather than replacing early frontline triage screening.

Why this matters on shift

Pediatric, emergency, and critical care nurses are responsible for identifying early clinical deterioration in children with suspected infection. Understanding that the Phoenix Sepsis Criteria excel at mortality risk stratification but have lower specificity in ICUs reinforces that nurses cannot rely solely on PSC scores to rule out evolving septic shock at the bedside.

Bedside takeaway

A meta-analysis of 16 cohorts (2,601,038 pediatric encounters) found Phoenix Sepsis Criteria outperformed 2005 IPSCC for predicting mortality (AUC 0.81 vs 0.71), but lower ICU specificity (0.48 vs 0.99 in ED) means it should not replace frontline screening.

Nursing implications

Utilize institutional rapid bedside screening protocols (vital signs, perfusion assessment, altered mental status) for early sepsis identification at triage, and apply Phoenix organ dysfunction criteria to track disease progression and escalate care in confirmed infection.

Limitations & cautions

Substantial heterogeneity across included studies; retrospective design in multiple cohorts; variable laboratory availability in lower-resource healthcare settings.
