🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
Circulation (2025) - Practice Guideline
Key Findings
- The 2025 update provides post-ROSC recommendations for initial blood pressure, oxygen, ventilation, and glucose goals to improve physiologic stabilization.
- New or updated guidance on seizures, temperature control, advanced neuromonitoring, and neuroprognostication aims to improve neurologic outcome assessment and survivorship care.
📋 Practice Implication: Use the updated AHA post-arrest framework to structure ICU stabilization, seizure evaluation, temperature management, and multimodal prognostication after ROSC.

Critical care medicine (2026) - Meta-Analysis
Key Findings
- Across 20,447 mechanically ventilated adults, conservative versus liberal oxygen targets showed no substantial difference in 90-day mortality (RR 1.01; 95% CI 0.94-1.09).
- In the post-cardiac arrest subgroup, conservative targets showed a possible survival benefit (RR 0.89; p = 0.05), while organ support-free days and adverse events were comparable overall.
📋 Practice Implication: Avoid assuming that higher oxygen targets improve outcomes after ROSC; titrate oxygen deliberately while awaiting condition-specific trial evidence.

Resuscitation (2025) - Meta-Analysis
Key Findings
- Among 762 post-ROSC AMI-cardiogenic-shock patients, temporary mechanical circulatory support did not improve longest-follow-up survival versus standard care (46% vs 41%; RR 1.10; 95% CI 0.94-1.29; p = 0.23).
- Patients with no cardiac arrest or an arrest duration under 10 minutes had improved survival with mechanical support (56% vs 45%; RR 1.25; 95% CI 1.06-1.47; p = 0.007), but device-related complications increased.
📋 Practice Implication: Reserve temporary mechanical support for carefully selected post-arrest shock patients rather than applying it routinely, and balance any subgroup benefit against device complications.

Critical care medicine (2026) - Meta-Analysis
Key Findings
- GFAP levels increased in patients with poor neurologic outcomes at 24 hours (Δ 138.1 pg/mL), 48 hours (Δ 471.1 pg/mL), and 72 hours (Δ 745.7 pg/mL) after ROSC.
- Prognostic accuracy improved over time, with summary AUC values of 0.76 at 24 hours, 0.84 at 48 hours, and 0.88 at 72 hours; moderate bias and absent standardized cutoffs limit routine use.
📋 Practice Implication: Treat GFAP as a promising adjunct to delayed multimodal prognostication, not as a standalone trigger for withdrawal of life-sustaining treatment.
|
Resuscitation (2026) - Meta-Analysis
Key Findings
- Across three randomized trials, video versus direct laryngoscopy showed no difference in first-pass intubation success (RR 0.88; 95% CI 0.63-1.22) or overall success (RR 1.00; 95% CI 0.90-1.12).
- Video laryngoscopy was associated with lower esophageal intubation rates, but observational evidence showed no consistent improvement in ROSC or survival and overall certainty was very low.
📋 Practice Implication: Choose the airway device according to operator skill and workflow; video laryngoscopy may reduce esophageal placement but should not be expected to improve survival by itself.

Summary
The highest-significance evidence emphasizes updated AHA adult advanced life support and post-cardiac arrest care, while recent syntheses address oxygen targets, temporary mechanical support, and GFAP-based neuroprognostication. Conservative oxygenation was comparable to liberal targets overall with a possible post-arrest survival benefit; routine mechanical support did not improve survival in unselected AMI-related cardiogenic shock after ROSC, whereas GFAP performance improved through 72 hours but remains investigational.
