Summary
Three practice-shaping papers stand out in anesthesiology and critical care: updated SCCM guidelines endorsing critical care ultrasonography (CCUS) to guide management with mortality benefit from targeted volume strategies; a focused PADIS update recommending dexmedetomidine over propofol, early mobilization, and melatonin in adult ICU care; and a large neonatal analysis showing neuromuscular blocker reversal reduces postoperative pulmonary complications. Together, they refine bedside imaging, sedation, and peri-extubation safety.
Research Themes
- Point-of-care ultrasound (POCUS/CCUS) to guide ICU management
- ICU sedation, mobilization, and sleep optimization (PADIS focused update)
- Pediatric anesthesia safety: neuromuscular blocker reversal and pulmonary outcomes
Selected Articles
1. Society of Critical Care Medicine Guidelines on Adult Critical Care Ultrasonography: Focused Update 2024.
This focused update synthesizes new evidence since 2016 and suggests using CCUS to guide management in septic shock, acute dyspnea/respiratory failure, and cardiogenic shock. Importantly, CCUS-guided targeted volume management is associated with improved mortality compared with usual care; evidence remains insufficient for cardiac arrest management.
Impact: Guidelines that align CCUS use with mortality benefits in volume management will shape ICU protocols and training, influencing widespread practice and research priorities.
Clinical Implications: Embed CCUS into protocols for shock states to guide fluid responsiveness and hemodynamic decisions; prioritize training and quality assurance in CCUS. Avoid overgeneralizing to cardiac arrest pending further evidence.
Key Findings
- CCUS is suggested to guide management in septic shock, acute dyspnea/respiratory failure, and cardiogenic shock.
- Targeted volume management using CCUS is associated with improved mortality compared with usual care.
- Insufficient evidence to recommend CCUS over standard care for cardiac arrest management.
Methodological Strengths
- Rigorous GRADE-based systematic review with evidence-to-decision framework
- Multidisciplinary panel with conflict-of-interest management and explicit PICO questions
Limitations
- Focused on five PICO applications; breadth may omit other CCUS uses
- Heterogeneity and limited randomized evidence in some domains (e.g., cardiac arrest)
Future Directions: Conduct multicenter RCTs on CCUS-driven protocols targeting hard outcomes; implementation science on training, credentialing, and quality control; evaluate cardiac arrest pathways.
2. A Focused Update to the Clinical Practice Guidelines for the Prevention and Management of Pain, Anxiety, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU.
This focused update recommends dexmedetomidine over propofol for ICU sedation, enhanced mobilization/rehabilitation, and melatonin to support sleep, while withholding recommendations for benzodiazepines in anxiety and antipsychotics for delirium. It broadens PADIS to include anxiety and emphasizes nonpharmacologic care alongside targeted pharmacologic choices.
Impact: Sedation and mobilization recommendations directly alter daily ICU practice and procurement, with potential downstream effects on delirium, ventilator duration, and recovery trajectories.
Clinical Implications: Prefer dexmedetomidine when feasible for ICU sedation; implement enhanced mobilization protocols; consider melatonin for sleep. Avoid routine benzodiazepines for anxiety and antipsychotics for delirium absent strong indications.
Key Findings
- Conditional recommendation for dexmedetomidine over propofol for sedation in adult ICU patients.
- Enhanced mobilization/rehabilitation and melatonin administration are suggested.
- No recommendation for benzodiazepines to treat anxiety or antipsychotics to treat delirium.
Methodological Strengths
- GRADE-based systematic reviews with explicit PICO and evidence-to-decision framework
- Inclusive, interprofessional task force with strict conflict-of-interest management
Limitations
- Predominantly conditional recommendations due to moderate/low certainty evidence in some areas
- Heterogeneous interventions and outcomes across included studies
Future Directions: Head-to-head RCTs comparing sedation strategies on delirium, ventilator-free days, and long-term outcomes; pragmatic trials for mobilization bundles; robust sleep interventions beyond melatonin.
3. Ventilation strategies and risk factors for intraoperative respiratory critical events and postoperative pulmonary complications in neonates and small infants: a secondary analysis of the NECTARINE cohort
In a 5,609-patient neonatal/infant cohort, intraoperative respiratory critical events occurred in 20.7% and PPCs in 17%. Pre-anesthesia respiratory disease and post-intubation NMBA use increased PPC risk, while neuromuscular blockade reversal (used in only 29.8%) was associated with substantially fewer PPCs, supporting routine reversal before extubation.
Impact: Provides high-quality pediatric anesthesiology evidence that NMBA reversal reduces PPCs, a modifiable perioperative risk with immediate practice implications.
Clinical Implications: Adopt routine neuromuscular blockade reversal before extubation in neonates/infants; screen for preexisting respiratory disease; standardize PPC prevention bundles regardless of ventilation mode.
Key Findings
- Intraoperative respiratory critical events occurred in 20.7% and PPCs in 17% of cases.
- Pre-anesthesia respiratory conditions and post-intubation NMBA use were associated with higher PPC risk.
- NMBA reversal was performed in 29.8%; lack of reversal increased PPCs (RR 1.50), while reversal reduced PPCs (RR 0.43).
Methodological Strengths
- Large, contemporary multicenter cohort focused on neonates and small infants
- Prespecified outcomes with clinically relevant effect estimates (relative risks)
Limitations
- Observational secondary analysis subject to residual confounding
- Limited detail on reversal agents/dosing and standardized ventilation protocols
Future Directions: Prospective interventional trials testing routine NMBA reversal strategies and PPC bundles; granular analyses of reversal agents, dosing, and timing; integration with neuromuscular monitoring adherence.
