1. HIgh versus STAndard blood Pressure target in hypertensive high-risk patients undergoing elective major abdominal surgery: the HISTAP multicenter randomized clinical trial.
In 630 hypertensive high-risk adults undergoing major abdominal surgery, targeting intraoperative MAP ≥80 mmHg (vs ≥65 mmHg) reduced the composite of postoperative mortality and major organ dysfunction (RR 0.78) and decreased acute kidney injury. Benefits occurred under continuous hemodynamic monitoring and protocolized fluids.
Impact: This pragmatic multicenter RCT directly informs intraoperative blood pressure targets, showing clinically meaningful reductions in organ dysfunction, especially kidney injury, in a common high-risk population.
Clinical Implications: For hypertensive high-risk patients undergoing major abdominal surgery, consider targeting MAP ≥80 mmHg with continuous monitoring and protocolized fluids to lower postoperative organ dysfunction, balancing vasopressor exposure and patient comorbidities.
Key Findings
- Primary composite outcome occurred in 38.1% (MAP≥80) vs 48.9% (MAP≥65); RR 0.78 (95% CI 0.65–0.93; P=0.006).
- Acute kidney injury was less frequent with MAP≥80 (23.5% vs 33.7%; P=0.005).
- Mean intraoperative MAP separation was achieved: 88±9 vs 77±7 mmHg.
- Trial pre-registered (NCT05637606); conducted at 18 centers with protocolized fluids and continuous monitoring.
Methodological Strengths
- Multicenter randomized design with intention-to-treat analysis
- Pre-registered trial with clear MAP separation and standardized perioperative care
Limitations
- Open-label hemodynamic targeting may introduce performance bias
- Population limited to hypertensive high-risk abdominal surgery; generalizability to other surgeries uncertain
Future Directions: Evaluate optimal MAP targets across broader surgical populations, assess long-term renal and cardiovascular outcomes, and define vasopressor strategies minimizing adverse effects.
PURPOSE: The optimal mean arterial pressure (MAP) target in high-risk hypertensive patients undergoing major abdominal surgery remains unclear. The HISTAP trial evaluated whether targeting an intraoperative MAP ≥ 80 compared with ≥ 65 mmHg reduces postoperative organ dysfunction and 30-day mortality, in this population. METHODS: HISTAP was a multicenter, randomized trial conducted at 18 Italian centers between March 2023 and April 2025. The study included patients aged ≥ 60 years with chronic hypertension requiring home therapy, undergoing elective major abdomina
2. Noninvasive Respiratory Support for Adult Patients with Acute Respiratory Failure. An Official American Thoracic Society Clinical Practice Guideline.
This ATS guideline issues strong recommendations for HFNC in acute hypoxemic respiratory failure and for NIV in acute hypercapnic respiratory failure, with conditional use of CPAP/NIV in hypoxemia and HFNC in mild hypercapnia (pH >7.25). It strongly recommends HFNC or NIV for preoxygenation before intubation and suggests HFNC for low-risk and NIV for high-risk patients post-extubation.
Impact: Comprehensive, methodologically rigorous guidance across key clinical scenarios will standardize NIRS use, reduce intubations, and improve peri-intubation and post-extubation outcomes.
Clinical Implications: Adopt HFNC as first-line for acute hypoxemia, reserve NIV/CPAP conditionally; prioritize NIV in acute hypercapnia, consider HFNC only in mild acidemia with close monitoring; use HFNC/NIV for preoxygenation and tailor post-extubation support to reintubation risk.
Key Findings
- Strong recommendation for HFNC in acute hypoxemic respiratory failure to reduce intubation.
- Strong recommendation for NIV in acute hypercapnic respiratory failure to reduce mortality and intubation.
- HFNC or NIV strongly recommended for preoxygenation prior to intubation to prevent desaturation.
- Post-extubation: suggest HFNC for low-risk and NIV for high-risk patients to lower reintubation.
Methodological Strengths
- GRADE-based recommendations informed by systematic reviews and network meta-analyses
- Multidisciplinary panel and risk-stratified, scenario-specific guidance
Limitations
- Heterogeneity in included studies and interfaces may limit generalizability
- Conditional recommendations reflect variable certainty; resource and tolerance constraints affect implementation
Future Directions: Prospective trials comparing NIRS modalities by phenotype and interface, implementation science to optimize uptake, and cost-effectiveness across settings.
BACKGROUND: Acute hypoxemic and hypercapnic respiratory failure are among the most common reasons for ICU admission and need for invasive mechanical ventilation. Noninvasive respiratory support (NIRS) strategies-including high-flow nasal cannula (HFNC), noninvasive ventilation (NIV), and continuous positive airway pressure (CPAP)-may prevent intubation, improve outcomes, and reduce ICU utilization. However, there is uncertainty regarding optimal patient and modality selection, resulting in variable implementati
3. Does intraoperative anesthesia handovers associated with adverse outcomes? A systematic review and meta-analysis.
Across 14 studies, intraoperative anesthesia handovers were significantly associated with higher adjusted risks of adverse outcomes, including composite in-hospital mortality and morbidity (aRR 1.44). Findings highlight the safety implications of provider transitions during surgery.
Impact: Identifies a modifiable systems factor linked to worse outcomes, providing a strong rationale for standardized, audited handover protocols and staffing models in anesthesia.
Clinical Implications: Implement structured, checklist-driven handovers, minimize non-essential provider transitions, and target high-risk cases for continuous anesthetist coverage to improve perioperative safety.
Key Findings
- Meta-analysis of 14 studies showed increased composite in-hospital mortality/morbidity with handovers (aRR 1.44, 95% CI 1.23–1.69).
- Association persisted across sensitivity and subgroup analyses despite heterogeneity.
- Errors linked to handovers likely multifactorial, highlighting need to define high-risk characteristics of transitions.
Methodological Strengths
- Pre-registered protocol (PROSPERO) with comprehensive multi-database search
- Random-effects modeling with subgroup and sensitivity analyses; NOS-based bias assessment
Limitations
- Predominantly observational evidence with residual confounding
- Heterogeneity in handover definitions and outcome measures
Future Directions: Prospective studies to define causal mechanisms, evaluate standardized handover bundles, and quantify benefits in high-risk surgeries and long cases.
BACKGROUND: Intraoperative anesthesia handover is a common occurrence; however, limited research has explored its impact on patient outcomes. The purpose of this systematic review and meta-analysis was to assess the effects of anesthesia handovers on adverse outcomes in surgical settings. METHODS: All clinical studies that specifically investigated the association between anesthesia handovers and adverse patient outcomes were included. The MEDLINE, Cochrane Library trials, PubMed, Embase, and Web of Science dat
