Curated with the assistance of AI (Perplexity). All content editorially reviewed.

This week: GPICS V3 redefines the minimum standards for every UK intensive care unit, the AAGBI/BIHS perioperative blood pressure guidelines raise the threshold for surgical delay — potentially ending thousands of unnecessary cancellations. Plus a practice-changing NEJM trial asks whether we really need arterial lines in all shocked patients, the FIBERTRACH RCT challenges routine bronchoscopy during tracheostomy, S-ketamine shows a compelling NNT of 8 for delirium prevention, and a BJA meta-analysis quantifies why femoral nerve blocks are falling out of favour.

GPICS Version 3 — Guidelines for the Provision of Intensive Care Services

FICM / ICS · Published 28 January 2026 · FICM announcement

The third edition of GPICS is the definitive reference for planning, commissioning and delivering adult intensive care in the UK — published a decade after GPICS V1 (2015). Key updates include: enhanced care (Level 1) integration with 30 new enhanced care interfaces; new terminology distinguishing "minimum standards" from "recommendations to provide a quality service"; new chapters on burn care, neurocritical care, and remote/rural ICUs; and updated workforce standards for ACCPs, nurses, and AHPs.

GPICS V3 covers airway management, respiratory, cardiovascular, renal, GI/nutrition, neurological, and infection control standards. It is the document by which ICUs are peer-reviewed by the CQC and other regulators — and underpins business cases for service development.

⚠ Tell your department: Download the full GPICS V3 PDF and review it against your unit's current configuration. The new minimum standards for enhanced care, workforce ratios, and remote/rural provision may require immediate service changes.

AAGBI/BIHS — Perioperative Blood Pressure Management Guidelines 2026

Anaesthesia · Published 14 January 2026 · DOI: 10.1111/anae.70082 · PubMed

The Association of Anaesthetists and British & Irish Hypertension Society have updated the 2016 joint guidelines on perioperative blood pressure management. Key changes:

⚠ Tell your department: Update your pre-assessment clinic BP thresholds for surgical cancellation. The new guidelines raise the "proceed" threshold — ensure all pre-assessment nurses and anaesthetists are briefed on the updated values to avoid inappropriate on-the-day cancellations.

Safe Drug Management in Anaesthetic Practice — 2026 Update

RCoA / Association of Anaesthetists / SALG · Published February 2026

The Royal College of Anaesthetists and the Association of Anaesthetists have jointly published the updated Safe Drug Management in Anaesthetic Practice guidance — the first revision since the 2020 publication. The guidance governs drug storage, access, and reconciliation across all anaesthetic environments (theatres, labour ward, ED, critical care, radiology).

Key principles: (1) Patient safety is the paramount priority above regulatory compliance; (2) Immediately Available Drugs (IADs) — including a neuromuscular blocking drug and vasoconstrictor — must be accessible without key/code/RFID lock; (3) Prefilled syringes are strongly recommended as tamper-evident, ready-to-use formats; (4) Departments must cultivate an open, vigilant culture addressing drugs of diversion risk for healthcare professionals.

⚠ Tell your department: Review local SOPs for drug storage against the 2026 guidance, particularly around IAD access procedures and drugs of diversion policy. Inspect whether emergency drugs are accessible without key actuation during a crisis.

NICE NG24 Blood Transfusion — TXA Expanded to All Surgical Bleeding

NICE · Updated 26 February 2026

NICE NG24 (Blood Transfusion) has been updated with new recommendations on tranexamic acid use in surgery. The previous threshold — TXA only for adults expected to lose >500ml — has been removed. TXA should now be offered if: surgery is performed in an operating theatre, there is a risk of bleeding, and the procedure will breach the skin or mucous membrane. The guidance is also extended to children using the same criteria.

The change is supported by new evidence demonstrating clinical safety and cost-effectiveness even for minor blood loss procedures. A 2024 national audit found that one in four eligible patients were not receiving TXA under the old guidance — this update simplifies decision-making and should increase appropriate use.

⚠ Tell your department: TXA is now indicated for virtually all operating theatre procedures with bleeding risk — no more estimating blood loss. Ensure pre-assessment and surgical team briefings reflect the new threshold. Relevant across ENT, orthopaedic, laparoscopic, and paediatric surgery.

CPOC — Best Practice Guidance: Perioperative Care Services for Children & Young People

Centre for Perioperative Care (CPOC) / RCoA · February 2026 Consultation

CPOC has published — for the first time — a best practice guidance document for perioperative care services for children and young people (aged 0–18 years), endorsed by the Royal College of Anaesthetists. The guidance describes how a CYP perioperative service should be established, delivered and governed in any hospital treating children, covering the full perioperative pathway from pre-assessment through to discharge.

The document is currently in consultation phase. Key themes include age-appropriate shared decision-making, anaesthetic lead for paediatric services, and minimum standards for safe paediatric anaesthetic environments.

EVERDAC — Do All Shocked Patients Need an Arterial Line? (NEJM)

N Engl J Med · November 2025 (featured in NEJM 12/19 March 2026 issue) · ICU Reach Summary

EVERDAC randomised 1,010 adults with shock (admitted to ICU within 24 hours; ~90% on vasopressors, ~54% septic shock) across 9 French ICUs to either: (a) noninvasive BP monitoring with automated brachial cuff — no arterial catheter in first 4 hours, or (b) early arterial catheter insertion within 4 hours (standard care). Arterial catheterisation was permitted later in the noninvasive group if prespecified safety criteria were met.

Outcome

Verdict: Noninvasive BP monitoring is noninferior to early arterial catheter insertion for 28-day mortality in ICU shock patients. Arterial lines carried a significantly higher risk of haemorrhage. This does not mean "never insert arterial lines" — but it challenges the reflex of early insertion in all shocked patients.

⚡ CONTROVERSY

The EVERDAC trial kept arterial lines out of the noninvasive arm even in patients on >100 μg/min norepinephrine — an extreme protocol unlikely to reflect most UK ICU practice. Critics note the trial was conducted in predominantly medical ICUs, limiting applicability to surgical or post-operative patients. The consensus interpretation is: in haemodynamically stable shock with adequate noninvasive monitoring, defer arterial line insertion — but retain clinical discretion in the surgical/post-op context.

ACTiVE Trial — Automated Ventilation vs Conventional: No Benefit in Ventilator-Free Days (JAMA)

JAMA · Published December 8, 2025; editorial March 12, 2026 · DOI: 10.1001/jama.2025.24384

1,514 critically ill adults requiring invasive mechanical ventilation at 7 ICUs (Netherlands and Switzerland) were randomised to INTELLiVENT-ASV (fully automated closed-loop ventilation) vs. protocolised conventional mechanical ventilation within 1 hour of ICU intubation.

Outcome

ACTiVE (ASV)

Conventional

VFD-28 (median)16.716.3
28-day mortality~27%~27%
Extubation failure (reintubation <24h)7.7%7.3%

The automated system showed numerically improved "ventilation quality" in the first 6 hours (more time in optimal respiratory physiology zones), but this was statistically non-significant after adjustment for multiple comparisons. The editorial (JAMA, March 2026) noted that highly optimised conventional ventilation protocols in academic ICUs is a significant barrier to demonstrating superiority of automation — this "ceiling effect" problem may limit generalisability to less-resourced settings.

FIBERTRACH — No Benefit to Routine Bronchoscopy During Percutaneous Tracheostomy

Crit Care Med · Published 2 March 2026 · DOI: 10.1097/CCM.0000000000007100 · PubMed

Multicenter RCT across 4 Spanish ICUs (n=442; 221 per arm) comparing routine fiberoptic bronchoscopy (FB) guidance vs. non-endoscopic percutaneous dilatational tracheostomy (PDT) by experienced intensivists. Primary outcome: perioperative complications.

Results: Complication rates were similar — FB group 11.3% vs. non-FB group 13.1% (95%CI −6.8 to 10.4; p=0.663). Critically, FB guidance was associated with higher peak inspiratory pressures (47.4 vs. 37.1 cmH₂O; p<0.001) and higher end-procedure PaCO₂ (44.3 vs. 41.5 mmHg; p=0.001), indicating FB adds physiological burden without reducing complications.

S-Ketamine Reduces Postoperative Delirium in Elderly Arthroplasty — NNT = 8

Anesthesiology · January 2026; 144(1):63–76 · DOI: 10.1097/ALN.0000000000005800 · PubMed

Double-blind RCT of 372 elderly patients (≥65 years) undergoing total hip or knee arthroplasty under neuraxial anaesthesia (not general). Patients randomised to S-ketamine (n=186) or normal saline placebo (n=186). Primary outcome: POD within 3 days.

Results: POD rate 8.06% (S-ketamine) vs. 20.43% (placebo); adjusted OR 0.29 (95%CI 0.14–0.63; p=0.002). NNT ≈ 8. S-ketamine also reduced pain during exercise and rescue analgesia. Side effects (hallucinations, dizziness, nightmares) were more common in the S-ketamine group but manageable.

PEFB vs PVB for Rib Fracture Analgesia — Noninferiority RCT

BJA · 2026; 136:677–686 · DOI: 10.1016/j.bja.2025.09.058 · PubMed

Level I trauma ICU RCT (France, n=90) comparing continuous posterior extrathoracic fascial plane block (PEFB), paravertebral block (PVB), and systemic analgesia in multiple rib fracture patients. Primary outcome: morphine consumption at 24h.

Results: PEFB was noninferior to PVB at 24h (17 vs. 22 mg morphine; p<0.001 for noninferiority). However, PEFB required rescue thoracic epidural in 30% vs. 6.7% for PVB (p=0.043), and PVB provided superior pain during coughing and better respiratory parameters.

Single-Shot Femoral Nerve Block and Falls Risk — RR 3.62 (BJA SR/MA)

BJA · Online January 2026 · DOI: 10.1016/j.bja.2025.11.018 · PubMed

MECIR/PRISMA-compliant systematic review and meta-analysis of 31 trials assessing fall, buckling, and near-fall risk following single-shot femoral nerve block (sFNB) after lower limb orthopaedic surgery.

Results: sFNB increased fall risk vs. non-motor-blocking techniques (RR 2.75; p=0.02), vs. neuraxial blockade (RR 6.35; p=0.03), and vs. systemic analgesia (RR 6.43; p=0.03). Overall RR for falls vs. no-block: 3.62 (95%CI 1.83–7.19; absolute risk increase 0.9%). Also increased buckling (RR 5.95) and near-falls (RR 4.56). Moderate certainty evidence.

PulmCrit: "Four Fatal Flaws in the New AHA/ACC PE Risk-Stratification System"

EMCrit / PulmCrit (Josh Farkas) · 7 March 2026 · Full post

Josh Farkas' detailed critique of the newly published 2026 AHA/ACC PE Guidelines identifies four fundamental problems with the new risk-stratification framework — of particular relevance to intensivists and anaesthetists managing perioperative PE:

⚡ CONTROVERSY

Farkas concludes: "Hospitals and clinicians should continue using their current PE algorithms rather than updating them based on the new guidelines." The ESC 2019 risk-stratification system remains the preferred framework in the UK. This post is essential reading before updating any departmental PE protocol.

THIS WEEK'S ACTION POINTS

  1. Download and read GPICS V3 — know the new minimum standards for your ICU. You'll need this for governance meetings, business cases, and your ARCP.
  2. Update your pre-assessment clinic BP thresholds — the new AAGBI/BIHS guidelines raise the "proceed" threshold, potentially reducing unnecessary on-the-day cancellations.
  3. Review your department's drug storage SOPs against the new RCoA/AAGBI Safe Drug Management 2026 guidance — particularly IAD access and drugs of diversion policy.
  4. Update your TXA prescribing practice: NICE NG24 now recommends TXA for all operating theatre procedures with any bleeding risk — no more estimated blood loss threshold.
  5. Revisit your ICU protocol for arterial line insertion in shock following EVERDAC — individualise rather than insert reflexively in all cases.
  6. Review your unit's PDT protocol following FIBERTRACH — routine bronchoscopy adds physiological burden without reducing complications when performed by experienced operators.
  7. Consider S-ketamine as a delirium-prevention adjunct in elderly patients undergoing arthroplasty under neuraxial anaesthesia (NNT≈8).
  8. Favour motor-sparing alternatives (adductor canal block, iPACK) over single-shot femoral nerve blocks for arthroplasty — the BJA SR/MA confirms RR 3.62 for falls.
  9. Before updating any departmental PE protocol, read the PulmCrit STRATIFY/PE guidelines critique — continue using ESC 2019 risk stratification, not AHA 2026.
