This month's issue is led by Euroanaesthesia 2026's landmark blood pressure finding: targeting MAP above 65 in noncardiac surgery — despite a compelling mechanistic case — does not improve outcomes in 15,603 patients across 15 RCTs. Two BJA articles this month demand protocol updates: a clear FiO2 washout signal (high oxygen causes atelectasis) and a PADDI preplanned analysis showing dexamethasone causes meaningful hyperglycaemia in diabetic patients. In obstetrics, the Lancet's three-paper PPH series consolidates the evidence for fibrinogen-first haemostasis. And the MHRA has issued two drug recalls requiring immediate stock checks.

Intraoperative Blood Pressure Targets in Noncardiac Surgery — Higher MAP (70–90) Does Not Improve Outcomes vs MAP 65

LEAD CHANGE THIS MONTH FINAL FRCA

This SR/MA (15 RCTs, n=15,603) presented at Euroanaesthesia 2026 in Rotterdam is the most comprehensive evaluation of intraoperative blood pressure targets yet assembled. Two parallel trials — the Veelo 3,500-patient Amsterdam trial and the IMPROVE-multi 1,300-patient German multicentre trial — anchored the analysis. Both stopped early for futility.

Primary findings: Higher MAP targets (70, 80, or 90 mmHg, individualised or fixed) compared with routine MAP 65 showed no difference in: (1) AKI (RR 0.95, 95% CI 0.85–1.06); (2) Acute myocardial injury (RR 1.02, 95% CI 0.94–1.12); (3) In-hospital or 30-day mortality (RR 1.00). The one signal was postoperative delirium (pooled RR 0.73, p=0.04) but trial sequential analysis confirmed this remained inconclusive — insufficient cumulative evidence for firm conclusions.

CRITICAL APPRAISAL

This is a robust finding. The physiological rationale for higher MAP targets — improved coronary and renal perfusion pressure — is compelling, but the clinical trials consistently fail to demonstrate patient benefit. Likely explanations: (1) Most surgery patients have adequate autoregulation at MAP 65, so higher targets add vasopressor exposure without end-organ benefit; (2) The trials may not have captured the patients most likely to benefit (those with impaired cerebrovascular autoregulation). The delirium signal (RR 0.73) is hypothesis-generating and supports the ASPIRE 85 trial now recruiting. Crucially: this does not mean hypotension is safe — profound hypotension (MAP <60 for >5 minutes) remains associated with harm and should be corrected urgently regardless of target strategy.

UK PRACTICE IMPLICATION

MAP 65 mmHg remains the validated standard for intraoperative blood pressure management in noncardiac surgery. Routine vasopressor use to maintain MAP >70 or >80 is not supported by RCT evidence and exposes patients to unnecessary vasopressor side effects (tachycardia, arrhythmia, peripheral ischaemia). However: individualise. Known cerebrovascular disease, severe aortic stenosis, or impaired cerebral autoregulation are scenarios where individual MAP targets above 65 remain clinically justified — these populations were often excluded from trials.

TELL YOUR DEPARTMENT

Target MAP ≥65 mmHg as the primary intraoperative blood pressure goal in elective noncardiac surgery. Do not routinely target MAP >70 without patient-specific indication. Correct any MAP <60 promptly regardless of baseline strategy.

High vs Low FiO2 During Anaesthetic Washout Before Extubation — High FiO2 Increases Postoperative Atelectasis: RCT

CHANGE THIS MONTH FINAL FRCA

The practice of administering high-flow 100% oxygen during the washout phase before extubation (to ensure rapid volatile agent clearance and pre-oxygenate against apnoea) is almost universal. This BJA RCT challenges that convention. Patients were randomised to FiO2 100%, 70%, or 40% during the washout period. Atelectasis was measured by electrical impedance tomography. The FiO2 100% arm showed significantly higher postoperative atelectasis on EIT compared with FiO2 40%. This is consistent with absorption atelectasis physiology: high FiO2 depletes nitrogen from alveoli, which are then absorbed by pulmonary capillary blood, causing alveolar collapse.

IMPLEMENTATION: CHANGE YOUR WASHOUT PROTOCOL

During the anaesthetic washout phase (end of surgery, before extubation): use FiO2 40–50% rather than 100%. This maintains adequate oxygenation during the washout period whilst preventing absorption atelectasis. The volatile agent will clear slightly more slowly at lower FiO2, but SpO2 remains safe with this approach in non-obese, non-compromised patients. For high-risk airways, obesity, OSA, or known difficult extubation: individualise — the safety margin from pre-oxygenation may justify FiO2 100% in these specific cases.

PENG Block in Femoral Neck Fractures — Prehabilitation and Pain: RCT Confirms Benefit

CHANGE THIS MONTH FINAL FRCA

The pericapsular nerve group (PENG) block targets sensory branches supplying the hip joint capsule (femoral nerve, obturator nerve accessory, articular branches) with a simple ultrasound-guided injection anterior to the hip capsule. This RCT specifically examined PENG block for prehabilitation in femoral neck fractures — the block was given early after fracture diagnosis (not just preoperatively) to enable patient mobilisation and physiotherapy before surgery.

Key findings: Patients receiving PENG block versus placebo had significantly reduced pain scores, were able to participate in prehabilitation physiotherapy, required less opioid analgesia before surgery, and had reduced postoperative opioid requirements. Femoral neck fractures in older adults are common ED presentations — offering PENG block in the acute setting (even before anaesthetic review) is feasible and evidence-supported.

UK PRACTICE: CONSIDER PENG BLOCK AT POINT OF CARE

PENG block for femoral neck fractures: straightforward technique (in-plane linear probe, 20mL 0.25–0.375% levobupivacaine, injection between iliopsoas and iliopectineal eminence). Can be performed by trained anaesthetists, emergency physicians, or orthopaedic surgeons in the ED or pre-assessment. The block provides analgesic benefit for 12–18h and allows earlier mobilisation. Review your trust's pathway for hip fractures — early PENG block should be available before operative anaesthetic review.

Opioid-Free Anaesthesia in VATS — SR/MA: Significantly Reduces PONV and Chronic Pain Without Compromising Haemodynamics

INFORMING PRACTICE FINAL FRCA

Opioid-free anaesthesia (OFA) typically combines dexmedetomidine, ketamine, lidocaine (and often local/regional anaesthesia) as opioid-sparing multimodal analgesia. This SR/MA specifically examined OFA in video-assisted thoracoscopic surgery (VATS), where PONV is a major issue due to thoracic manipulation and single-lung ventilation. Results: OFA significantly reduced PONV and chronic postoperative pain compared with opioid-based approaches. Intraoperative bradycardia was more frequent with OFA (predominantly due to dexmedetomidine), but hypotension rates were similar. This evidence supports OFA adoption for elective VATS in eligible patients.

CRITICAL APPRAISAL

The chronic pain reduction is the most clinically significant finding — persistent post-thoracotomy/post-VATS pain is underappreciated and contributes significantly to post-discharge opioid use. The mechanism may be opioid-induced hyperalgesia prevention. However, OFA requires a well-structured multimodal protocol (dexmedetomidine infusion, epidural or ESPB/ICNB, paracetamol + NSAID, ketamine bolus) and careful patient selection — not appropriate for haemodynamically unstable patients or those with severe bradyarrhythmia risk. Ensure your institution has an OFA protocol before adoption.

Enteral vs IV Magnesium Replacement in Critically Ill Adults — Non-Inferior at 72 Hours

CHANGE THIS MONTH FINAL FRCA

Hypomagnesaemia (serum Mg <0.75 mmol/L) is present in 40–65% of ICU patients and is associated with refractory hypokalaemia, atrial arrhythmias, and prolonged ventilation. Standard replacement is IV magnesium sulphate (10–20 mmol over 60 minutes, repeated daily). This non-inferiority RCT (McMaster 6/7) demonstrates enteral magnesium via NGT achieves equivalent serum levels at 72 hours with less IV access requirement and fewer phlebitis events in haemodynamically stable ICU patients. For surgical ICU patients in the early postoperative period with NGT in situ: enteral Mg is a practical and evidence-based alternative to IV.

VExUS Venous Excess Ultrasound Grading System — SR/MA Confirms Predictive Value; IVC-Gating Limitation in ICU

INFORMING PRACTICE FINAL FRCA

VExUS (IVC diameter + hepatic, portal, and intrarenal Doppler) Grade 2–3 reliably predicts AKI and poor outcomes in critical illness, as confirmed by this SR/MA. Increasingly relevant for perioperative fluid management: post-cardiac surgery and post-major abdominal surgery patients accumulate venous congestion that causes end-organ injury. A technical caveat for ICU use: IVC dilatation (≥2 cm) as an entry criterion misses organ Doppler abnormalities in patients where IVC is not dilated — assess hepatic and portal Doppler directly if congestion is clinically suspected.

REBOARREST: Prehospital REBOA in Non-Traumatic OHCA — Neutral on All Outcomes

INFORMING PRACTICE

REBOA in non-traumatic OHCA aimed to improve coronary and cerebral perfusion during CPR. REBOARREST found no improvement in ROSC, survival, or neurological outcome versus standard ALS. Consistent with ECPR data — the intervention complexity appears to eliminate any haemodynamic gain in non-traumatic arrest. Does not apply to traumatic cardiac arrest (zone-1 REBOA for haemorrhagic arrest). For anaesthetists involved in cardiac arrest response: do not adopt REBOA for medical OHCA based on current evidence.

CHANGE WHEN GUIDELINE UPDATES FINAL FRCA

AREANEW NG258 REQUIREMENT
Tryptase samplingThree samples: 30–120 min (peak); 3–4 hours; and baseline (>24h or at follow-up). All three required for meaningful interpretation.
Observation periodMinimum 4–6 hours. Severe/incomplete response: 24h admission.
Allergy referralMandatory for all confirmed or suspected anaphylaxis — document at discharge.
DocumentationSuspected trigger (all drugs/agents used), severity, treatment, tryptase results, referral confirmation — all required in anaesthetic record.

PERIOPERATIVE ANAESTHESIA POINT

Perioperative anaphylaxis most commonly occurs at induction. For any suspected intraoperative anaphylactic reaction: (1) stop all agents and list ALL drugs given; (2) draw first tryptase at 30–120 min from event onset — this is time-critical and often missed in post-event management; (3) draw second tryptase at 3–4 hours; (4) arrange baseline tryptase at 24h or outpatient follow-up; (5) make allergy referral before patient leaves hospital. Update your departmental perioperative anaphylaxis protocol and anaesthetic record template to capture all three sample timings.

Two major UK maternity safety reports (Ockenden Nottingham Review, 24 June; Baroness Amos Final Report, 30 June) both call for binding national maternity standards. RCoA and OAA have jointly endorsed recommendations. Both reports highlight inadequate anaesthetic presence in maternity emergencies and communication failures between teams. OAA leads should: (1) review 24-hour anaesthetic cover arrangements for obstetric units; (2) audit emergency team communication protocols; (3) review consent and communication practices for women from Black and Asian backgrounds regarding epidural provision and pain management.

DigiSep Trial: Clinical Metagenomics in Sepsis — RCT Impact on Outcomes, Costs, and Quality of Life

INFORMING PRACTICE FINAL FRCA

Clinical metagenomics (sequencing all microbial DNA in a blood or bronchoalveolar sample simultaneously, bypassing culture) is an emerging diagnostic approach for ICU sepsis. The DigiSep trial — the first adequately powered RCT — evaluated whether metagenomics-guided management improved outcomes in sepsis/septic shock patients compared with standard culture-based microbiology. Outcomes included clinical outcomes, healthcare costs, and health-related quality of life. Published by the German Society of Anaesthesiology and Intensive Care (GSAIC) Trials Group in ICM, 30 June 2026.

CLINICAL SIGNIFICANCE

Clinical metagenomics offers pathogen identification within 6–12 hours (vs 24–72h for standard cultures) and detects organisms missed by conventional culture (fungi, atypical bacteria, viruses, polymicrobial infections). The DigiSep result will determine whether faster pathogen identification translates to antibiotic deescalation, shorter ICU stays, or improved mortality. This trial is highly relevant to UK ICUs considering whether to commission metagenomics services. Watch for the full results at PubMed PMID: 42377463.

Bicarb in ICU is only supported by RCT evidence at: pH ≤7.20 AND AKI Stage 2-3 AND on vasopressors (BICAR-ICU criteria). Outside this: BIHCA and SODa-BIC confirm bicarb does not improve outcomes and causes hypernatraemia and alkalosis. Update your ICU default prescribing accordingly. Bicarb remains appropriate for: TCA overdose (QRS prolongation), hyperkalaemic arrest, and metabolic alkalosis correction in specific scenarios — but not for routine acidosis management in shock.

Postpartum Haemorrhage 2026 — Lancet Series: Epidemiology, Prevention, and Diagnosis & Treatment

CHANGE WHEN GUIDELINE UPDATES FINAL FRCA

The Lancet published a major three-paper PPH series in June 2026, consolidating the evidence base for the most common cause of maternal mortality globally. Each paper covers a distinct phase of the PPH challenge:

PAPERFOCUSKEY MESSAGES FOR OBSTETRIC ANAESTHESIA
Paper 1: EpidemiologyConsequences and missed opportunities1 in 25 deliveries globally; UK rates rising (14.6 per 1000 births). Black and Asian women at higher risk. Early involvement of anaesthetic team reduces mortality.
Paper 2: PreventionFrom evidence to implementation at scaleOxytocin 10 IU IM/IV remains first-line. Carbetocin for high-risk CS. TXA prophylaxis reduces PPH rate when given before skin closure in high-risk cases. Heat loss prevention. Delayed cord clamping compatible with TXA timing.
Paper 3: Diagnosis and treatmentA race against timeFibrinogen-first: targeted haemostasis based on ROTEM/TEG or fibrinogen <2g/L. Fibrinogen concentrate or cryoprecipitate. Avoid FFP as first-line in PPH (poor fibrinogen efficiency). Cell salvage for massive PPH. Early ICU involvement for haemodynamic instability.

KEY PRACTICE CHANGES — OBSTETRIC ANAESTHESIA

The strongest new messages: (1) Fibrinogen replacement (not FFP) first when ROTEM/TEG or fibrinogen <2g/L — fibrinogen concentrate or cryoprecipitate; (2) TXA 1g IV should be given early in PPH (not just in severe haemorrhage) consistent with WOMAN trial; (3) Cell salvage should be immediately available for high-risk deliveries; (4) Black and Asian women have higher PPH risk — ensure parity of documentation, early escalation, and access to cell salvage regardless of patient preference regarding autologous blood.

Intraoperative Dexamethasone 8mg and Glycaemic Response in Patients with Diabetes — PADDI Preplanned Analysis

CHANGE THIS MONTH FINAL FRCA

Dexamethasone 8mg IV is now near-universal in elective surgery as antiemetic prophylaxis. The PADDI trial (over 8,000 patients) evaluated whether dexamethasone increased surgical site infections — it did not. This preplanned subgroup analysis of patients with diabetes mellitus examines the glycaemic consequences specifically. Dexamethasone 8mg at induction caused clinically significant hyperglycaemia in diabetic patients, peaking 2–4 hours post-administration and persisting into the postoperative period.

CLINICAL IMPLICATION

If you routinely give dexamethasone 8mg IV to all elective surgical patients (which is best practice for PONV prophylaxis), then for patients with diabetes (both type 1 and type 2, and steroid-dependent patients): plan glucose monitoring 2-4 hours post-induction and arrange postoperative glucose checks before discharge or within the first HDU check. Consider insulin sliding scale or modified VRIII protocol for high-risk diabetic patients receiving dexamethasone. This does not mean withholding dexamethasone — the PONV prevention benefit outweighs the manageable hyperglycaemia risk — but it requires active glucose management planning.

SSC 2026 Update — Brief Summary (see Issues 3 & 4 for full coverage). The 2026 Surviving Sepsis Campaign guidelines (129 statements, 46 new) added several practical ICU points not previously highlighted: mucolytics (carbocisteine, HTS) are now explicitly NOT recommended in mechanically ventilated patients following the MARCH trial harm signal (carbocisteine: GI bleed RR 6.51; HTS: bronchoconstriction RR 5.73). Antibiotic deescalation upgraded from suggestion to recommendation when susceptibilities available. Source control within 6 hours where feasible.

ANZCA 2026 GLP-1 Agonist Perioperative Guidance Update (see Issues 3 & 5 for full coverage). ANZCA updated guidance recommends against routinely withholding GLP-1 agonists preoperatively — the risk of hyperglycaemia and disease disruption may equal or exceed the poorly-quantified aspiration risk. Individual assessment remains appropriate where clinical gastroparesis is present. RCoA/AAGBI UK-specific guidance expected. For patients with known GLP-1-related GI symptoms: extended fasting (8h solids) and consider RSI if any doubt about gastric emptying.
