High-yield critical care science, written every week

Targeted temperature,fluid overload limits,and neuromuscular control

Welcome to Issue #5. This week we synthesize updated consensus frameworks on post-cardiac arrest temperature regulation, scrutinize fluid responsiveness versus oliguria in septic AKI, and review neuromuscular blockade strategies in moderate-to-severe ARDS.

Temperature control in acute brain injury

Intensive Care Med · 2026 · DOI: 10.1007/s00134-026-08367-9

This 2026 statement reconciles conflicting post-cardiac arrest trials (TTM-1 vs TTM-2) and extends targeted temperature control principles to traumatic brain injury and hypoxic-ischemic brain injury (HIBI).

The framework reinforces strict normothermia (36.5°C–37.5°C) as the non-negotiable minimum standard, while reserving moderate hypothermia (32°C–34°C) for refractory intracranial hypertension or severe cerebral edema. Active fever control using feedback-controlled cooling devices remains superior to passive cooling.

Effectiveness of Nurse-Led, Touch-Based Intervention in Improving Informal Caregivers' Engagement

Nurs Open · 2026 · n = 228 dyads (protocol) · DOI: 10.1002/nop2.70733

This trial protocol describes a two-arm cluster RCT in neonatal intensive care evaluating a structured, touch-based caregiver involvement model.

Because this publication is purely a study protocol, direct clinical outcomes remain unproven (CEBM Level 5). However, it highlights the growing emphasis on family-centered interventions in high-acuity environments.

The Effects of Virtual Reality Applications on Perceived Stress, Anxiety and Fatigue Among Nurses Working in the Intensive Care Unit

Nurs Crit Care · 2026 · n = 60 · DOI: 10.1111/nicc.70617

A randomized controlled trial testing short VR sessions during work breaks against standard rest periods for adult ICU nurses.

The intervention group demonstrated significant reductions in Perceived Stress (PSS-10, p < 0.001), State Anxiety (STAI-S, p < 0.001), and Fatigue (FSS, p < 0.001) compared to controls.

Fluid Stewardship01

Oliguria is a physiological signal, not an automatic fluid bolus mandate

Isolated oliguria (< 0.5 mL/kg/h) in hemodynamically stable patients with septic AKI frequently reflects vasomotor tone alteration or ADH release, not fluid responsiveness. Administering crystalloid boluses without passive leg raise (PLR) or velocity-time integral (VTI) evidence increases venous congestion and worsens renal perfusion pressure.

ARDS Therapeutics02

Re-evaluating Neuromuscular Blockade: ACURASYS vs. ROSE

Continuous NMBAs for 48 hours (ACURASYS) improve oxygenation and lower barotrauma risk in severe ARDS (PaO2/FiO2 < 120) with strong patient-ventilator dyssynchrony. However, routine paralysis under deep sedation (ROSE) offers no survival benefit over light sedation. Reserve early cisatracurium for severe dyssynchrony or refractory driving pressure > 15 cmH2O.

Neurocritical Care03

Corneal and pupillary reflexes post-arrest

Bilateral absence of pupillary light and corneal reflexes at > 72 hours post-ROSC remains a highly specific predictor of poor neurological outcome (false positive rate near 0%), provided neuromuscular blockers and hypothermia-induced metabolic suppression have cleared.

Closing note

It is what we think we know already that often prevents us from learning.
Claude Bernard · Experimental Medicine · 1865

Re-evaluating classic paradigms—whether hypothermia target depth, fluid boluses for oliguria, or routine paralysis in ARDS—requires clinical humility. True stewardship means matching interventions to granular physiology, not habit.
