ISTH updates factor-concentrate guidance for perioperative bleeding

Journal of thrombosis and haemostasis : JTH (PubMed)Aug 28, 2026

AI-summarized from the linked source. Educational brief, not medical advice.

Brief summary

Updated ISTH guidance reviews current evidence and expert consensus on fibrinogen, prothrombin complex, recombinant factor VIIa, and factor XIII concentrates for acquired perioperative coagulopathy.

What NurseJet pulled from the source

The guidance addresses major surgical bleeding in cardiac, trauma, obstetric, and transplant settings. It describes acquired perioperative coagulopathy as multifactorial and updates the ISTH's 2018 document using newer clinical studies, systematic reviews, evolving practice, and expert consensus. The PubMed abstract establishes the agents and settings covered but does not provide dosing or individual recommendation strength.

Why this matters for nurses

Critical-care, emergency, perioperative, and obstetric nurses coordinate rapid assessment, specimen collection, blood-product and medication administration, warming, monitoring, and escalation during major bleeding. The update provides a current evidence framework for multidisciplinary protocols without replacing local algorithms or prescriber-directed selection.

Bedside takeaway

Use the current multidisciplinary bleeding protocol and verify every factor concentrate rather than treating the agents as interchangeable.

How This Applies in Practice

Use this when: Supporting a patient with major perioperative, traumatic, obstetric, or transplant-related bleeding and an activated coagulation-management pathway.

On your shift

Communicate the bleeding source, estimated loss, temperature, hemodynamic trend, transfusions, medications, and ordered coagulation results to the response team.
Verify the prescribed concentrate, indication, dose, route, compatibility, and required monitoring with the approved protocol before administration.
Trend clinical bleeding, hemodynamics, laboratory response, and possible thrombotic or transfusion-related complications and escalate changes promptly.

Keep in mind: The abstract does not define product-specific dosing or selection. Follow the major-bleeding protocol, facility policy, and provider orders.

Key takeaways

The ISTH document covers factor-concentrate use for bleeding in cardiac surgery, trauma, obstetric care, and organ transplantation.
It reviews fibrinogen concentrate, prothrombin complex concentrate, recombinant activated factor VII, and factor XIII concentrate.
The guidance incorporates evidence published since the prior 2018 ISTH guidance and evolving bleeding-management practice.
Its pragmatic guidance is based on the available evidence and expert consensus; the abstract does not support a single universal regimen.

Practice implications

Activate the approved major-bleeding pathway, communicate the surgical context and evolving blood loss, obtain ordered coagulation testing promptly, and verify the exact product, dose, route, and monitoring plan before administration. Track response and complications through the local protocol.

Limitations & cautions

The accessible PubMed abstract describes the guidance scope but does not list agent-specific indications, contraindications, doses, evidence certainty, or recommendation strength. Those details require review of the full guidance, and expert consensus contributes where evidence is limited.

Renal failure (PubMed)Sep 7, 2026Research Article

A single-center retrospective cohort found that approximately one quarter of laboratory-defined acute kidney injury cases on internal medicine wards were not documented, particularly when maximal creatinine was lower.

Med-SurgAI summaryReview source

Research ArticleResearchQuality ImprovementAI summary · original source linked below

Among 161 adult hospitalizations meeting serum-creatinine criteria for acute kidney injury, 39 cases (24.2%) were undocumented. Length of stay and in-hospital mortality did not differ significantly by documentation status.

Key takeaways

In the 149 hospitalizations with a demonstrable creatinine change, 33 cases (22.1%) were undocumented.
Higher maximal creatinine was associated with lower adjusted odds of underdocumentation.
The study did not test whether a detection or documentation intervention improves care or outcomes.

Why this matters on shift

A smaller creatinine rise may receive less attention even when it meets the study's laboratory definition of acute kidney injury, which can affect how renal risk is communicated across the inpatient team.

Bedside takeaway

Trend ordered renal-function results and communicate clinically important changes through local escalation and documentation workflows.

Nursing implications

Trend ordered renal-function results and communicate clinically important changes through the care team according to local escalation and documentation workflows.

Limitations & cautions

Abstract-only summary. This was a retrospective, single-center study of 161 hospitalizations; urine-output criteria and reliable preadmission creatinine values were unavailable, and the reference creatinine method may affect case classification.

Journal of midwifery & women's health (PubMed)Sep 7, 2026Research Article

A retrospective analysis of US natality data found no statistically significant yearly difference in neonatal mortality between freestanding birth centers and hospitals among term, singleton, vertex births without major medical risk factors from 2015 through 2024.

L&D / OB PedsAI summaryReview source

Research ArticleResearchPatient EducationAI summary · original source linked below

Adjusted neonatal-mortality odds for freestanding birth centers fluctuated around 1.0 across the 10-year study period. No individual year showed a statistically significant difference from hospital births, including 2020 and 2021 when birth-center volume increased.

Key takeaways

The analysis was restricted to births meeting selected low-risk criteria.
The study found no evidence that higher birth-center use during the pandemic years increased neonatal mortality.
The observational design cannot establish that birth setting itself caused the mortality pattern.

Why this matters on shift

The findings add national outcome data for counseling and systems planning around freestanding birth-center care for appropriately selected low-risk pregnancies.

Bedside takeaway

Apply local eligibility, surveillance, escalation, and transfer protocols when caring for planned low-risk birth-center patients.

Nursing implications

Keep eligibility, surveillance, escalation, and transfer decisions anchored to local birth-center criteria and maternal-newborn protocols.

Limitations & cautions

Abstract-only summary. The study used retrospective vital-record data, was limited to selected low-risk births, and cannot exclude residual differences between people who delivered in birth centers and hospitals.

Pediatric emergency care (PubMed)Sep 7, 2026Research Article

A double-blind randomized trial found no reduction in vomiting or faster oral tolerance with intravenous pantoprazole versus placebo in children with acute gastroenteritis and persistent vomiting after ondansetron.

Peds EmergencyAI summaryReview source

Research ArticleResearchMedication SafetyAI summary · original source linked below

The trial randomized 100 children. Vomiting episodes and oral tolerance at 6 and 12 hours did not differ significantly, while median hospital stay was 2 days with pantoprazole and 1 day with placebo.

Key takeaways

The median participant age was 14 months, and 67% of participants were male.
Oral tolerance at 12 hours was 86% in both groups.
The longer stay associated with pantoprazole requires cautious interpretation because this was a single-center trial.

Why this matters on shift

The trial does not support empiric intravenous proton-pump inhibition for persistent vomiting in pediatric acute gastroenteritis after ondansetron.

Bedside takeaway

Clarify the indication for empiric acid suppression and keep hydration and oral-tolerance assessment central to care.

Nursing implications

Prioritize the ordered hydration and oral-tolerance plan, document ongoing emesis, and clarify the indication before administering empiric acid suppression.

Limitations & cautions

Abstract-only summary. This was a single-center study of 100 children in Tehran, and the abstract does not describe adverse events or explain why hospitalization was longer in the pantoprazole group.
