Decongestion Strategies,ICP Monitoring in TBI,and Bedside Hemodynamics

Welcome to Issue #8 of ICU Weekly. This week, we dissect a comprehensive network meta-analysis on diuretic strategies in the critically ill, evaluate the clinical impact of ICP monitoring in severe traumatic brain injury, and review essential bedside practices including POCUS, transfusion thresholds, and post-arrest neuroprognostication.

Diuretic therapy for critically ill patients: a systematic review and network meta-analysis

Annals of Intensive Care · 2026 · DOI: 10.1016/j.aicoj.2026.100120

This network meta-analysis evaluated various diuretic strategies (continuous infusion vs. intermittent boluses, and loop diuretics alone vs. combination with thiazides, metolazone, or acetazolamide) in critically ill patients with fluid overload.

The primary outcomes assessed were resolution of fluid overload, incidence of acute kidney injury (AKI), and mortality. The study synthesized data from multiple randomized controlled trials to establish a hierarchy of efficacy and safety among the different regimens.

Impacts of intracranial pressure monitoring on mortality and length of stay in severe traumatic brain injury: a systematic review and meta-analysis

Eur J Trauma Emerg Surg · 2026 · n = 121,799 · DOI: 10.1007/s00068-026-03302-5

This systematic review and meta-analysis of 31 studies (including 121,799 patients) evaluated the association between intracranial pressure monitoring (ICPm) and clinical outcomes in severe traumatic brain injury (sTBI).

Pooled crude analysis demonstrated lower mortality in the ICP-monitored group (OR 0.79, 95% CI 0.68–0.91, p = 0.002), though heterogeneity was extremely high (I² = 92%). ICU and hospital lengths of stay were longer in the monitored group, and functional outcomes did not show a consistent benefit.

Effectiveness of Nurse‐Led, Touch‐Based Intervention in Improving Informal Caregivers' Engagement and Perceptions of Nurse Support During Neonatal Nursing Care: Protocol for Cluster Randomized Controlled Trial

Nursing Open · 2026 · Protocol · DOI: 10.1002/nop2.70733

This protocol outlines a two-arm parallel cluster randomized controlled trial (n=228 dyads) designed to evaluate a nurse-led, touch-based intervention grounded in caring theory.

The study aims to measure informal caregivers' engagement and perceptions of nursing support in the neonatal intensive care unit (NICU), establishing a structured framework for caregiver-neonate bonding.

TLS as Predictors and Targets in Neoadjuvant Chemoimmunotherapy for NSCLC

Thoracic Cancer · 2026 · DOI: 10.1111/1759-7714.70375

This review highlights the role of tertiary lymphoid structures (TLS) as critical prognostic biomarkers and therapeutic targets in neoadjuvant chemoimmunotherapy for non-small cell lung cancer (NSCLC). TLS facilitate local antigen presentation and immune activation, correlating with improved survival and checkpoint inhibitor responsiveness.

Machine Learning Models for Predicting Pain, Fatigue, Depression, Anxiety, and Malnutrition in Cancer Patients: A Systematic Review and Meta‐Analysis

J Nurs Scholarsh · 2026 · DOI: 10.1111/jnu.70123

A systematic review and meta-analysis of 34 studies evaluating machine learning models to predict cancer-related symptoms. The pooled AUCs ranged from 0.76 (pain, depression) to 0.86 (malnutrition), demonstrating acceptable discriminative performance but high heterogeneity and a lack of external prospective validation.

Hemodynamics01

POCUS in Undifferentiated Shock

The RUSH protocol (Rapid Ultrasound in Shock) is essential for bedside differentiation of distributive, cardiogenic, hypovolemic, and obstructive shock. Integrating VExUS (Venous Excess Ultrasound) scoring helps assess venous congestion, preventing harmful fluid overload during resuscitation.

Hematology02

Restrictive vs. Liberal Transfusion in the ICU

Robust evidence from trials like TRICC and TRISS supports a restrictive transfusion threshold (Hb < 7 g/dL) for most critically ill patients. This strategy reduces transfusion-related acute lung injury (TRALI) and circulatory overload (TACO) without increasing mortality, except in patients with active myocardial ischemia.

Neurocritical Care03

Neuroprognostication Post-Cardiac Arrest

Accurate neuroprognostication requires a multimodal approach. Guidelines recommend waiting at least 72 hours after return of spontaneous circulation (ROSC) and rewarming, combining clinical examination (pupillary reflexes), electrophysiology (EEG, somatosensory evoked potentials), and biomarkers (NSE, S-100B) to avoid premature withdrawal of life-sustaining therapy.

Closing note

Science is a way of thinking much more than it is a body of knowledge.
Carl Sagan · Broca's Brain · 1979

As intensivists, we are often forced to make rapid decisions with incomplete data. True clinical humility lies in recognizing the limitations of our evidence, constantly questioning our protocols, and adapting our bedside practices as high-quality science evolves.
