Critical careCluster-randomized crossover trial

CRITICAL CARE · OCTOBER 29, 2026

Adding chlorhexidine to standardized mechanical oral care did not reduce ventilator-associated pneumonia.

Across 1,035 ventilated adults and 10,024 ventilator-days, twice-daily 0.12% chlorhexidine produced a VAP rate of 18.8 versus 16.9 per 1,000 ventilator-days without chlorhexidine.

FRONTLINE FIVE EM INTERPRETATION

Preserve toothbrushing, moisturization, suctioning, and secretion management, but do not assume routine chlorhexidine adds benefit. The nonsignificant result does not prove equivalence, and the confidence interval permits modest benefit or harm.

Critical careSystematic review & meta-analysis

Albumin did not reduce acute kidney injury during critical-care fluid resuscitation.

Across nine randomized trials and 11,778 patients, albumin produced a pooled AKI risk ratio of 1.00; renal-replacement therapy was more frequent in the pooled analysis, driven by 20% albumin trials.

CardiologyMulticenter randomized trial

Left bundle-branch area pacing reduced the 24-month composite outcome compared with right ventricular pacing.

In 482 analyzed patients with AV block, preserved LVEF, and high expected pacing burden, the primary composite occurred in 2.4% versus 12.5%.

Septic shockMulticenter retrospective cohort

Inter-clinician diagnostic disagreement marked a more complex septic-shock phenotype.

Among 2,233 patients, disagreement was documented in 9.5%. The overall mortality association was not significant; a culture-positive subgroup signal remained imprecise and cannot establish causation.

Critical carePropensity-adjusted cohort

Plasma exchange showed an adjusted survival association in streptococcal septic shock.

Among 149 adults at three tertiary ECMO centers, 31 received rescue plasma exchange. Adjusted analyses favored treatment, but severe baseline imbalance and multiple time-related biases prevent a causal claim.
