This prospective clinical audit evaluated adherence to recommended qNM monitoring standards in adult patients undergoing general anesthesia at a major Portuguese tertiary hospital. Over five predefined weekdays between March and May 2025, all adult patients receiving general anesthesia across six operating or procedural areas were assessed. Of 329 patients included, 308 (93.6%) received NMBAs. Quantitative neuromuscular monitoring was omitted in 13.0% despite universal device availability.

The aim of this pilot study was to evaluate the feasibility and preliminary effects of a tablet-based augmented reality (AR) system integrated into routine perioperative patient transfer on preoperative anxiety in pediatric patients. In this single-center, quasi-experimental pilot study, 27 pediatric patients aged 3-10 years were assigned to an AR (n = 13) or control (n = 14) group based on surgery month. The AR system, implemented on a standard tablet device, overlaid virtual characters onto real-world surroundings to guide patients from the surgical center entrance to the operating room. The primary outcome was preoperative anxiety assessed using the modified Yale Preoperative Anxiety Scale (mYPAS) at operating room entry. Secondary outcomes included guardian-rated comfort visual analog scale scores and postoperative agitation. The AR group was younger than the control group. Median mYPAS scores at operating room entry were lower in the AR group than in the control group (28.3 [23.3-36.7] vs. 40.0 [36.7-52.9]; median difference - 11.7; 95% CI, - 18.4 to - 1.60; p = 0.01).

Patients undergoing gastric cancer surgery often present with anemia, which may impair microvascular endothelial function and tissue oxygenation. How preoperative anemia influences intraoperative sublingual microcirculation and macro- and micro-circulatory coherence under GDFT is not known. Patients undergoing open radical gastrectomy were divided into anemic and non‑anemic groups according to their hemoglobin (Hb) levels. All patients received GDFT guided by pulse pressure variation. Sublingual microcirculatory (microvascular flow index [MFI], proportion of perfused vessels [PPV], total and perfused vessel density) and macrocirculatory (cardiac index [CI] and mean arterial pressure [MAP]) variables were measured before (T0) and immediately after induction of general anesthesia (T1), after tumor resection (T2) and at the end of surgery (T3). Mixed linear models were used to compare intergroup differences in sublingual microcirculation over time, and to analyze the correlations between macro- and micro-circulatory variables. Correlations between preoperative Hb and changes in MFI from each intraoperative time point to T0 were additionally assessed. A total of 49 patients were analyzed in present study. MFI showed a significant group‑by‑time interaction between the two groups (P = 0.030). In anemic patients (n = 22), MFI was significantly lower than that in non‑anemic patients (n = 27) at T1 (P = 0.013), and between-group differences were no longer evident at T3 (P = 0.461) under GDFT, although MFI remained below baseline in both groups. PPV was lower in anemic patients at T2 (P = 0.010). Correlation analyses demonstrated that lower preoperative Hb levels were associated with greater reductions in ΔMFI from T1 to T0 (Pearson's r = 0.343, P = 0.016) and T2 to T0 (Spearman's ρ = 0.369, P = 0.009). No significant associations were found between macro- and micro-circulatory variables in either group. Under GDFT, anemic patients exhibited greater perioperative alterations in sublingual microcirculation, particularly after anesthesia induction and tumor resection. Lower preoperative Hb concentrations were associated with greater reductions in MFI. Further, the lack of detectable associations between macrocirculatory and sublingual microcirculatory variables suggests that conventional hemodynamic targets may not fully reflect sublingual microvascular perfusion in this vulnerable population.Trial registration number: NCT07583927.</p>","PeriodicalId":15513,"journal":{"name":"Journal of Clinical Monitoring and Computing","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149194149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acute kidney injury may occur early, since the kidney is particularly vulnerable to elevated intra-abdominal pressure (IAP). Accurate and timely measurement of IAP is essential for early detection of IAH and the initiation of appropriate therapeutic interventions. Therefore, the aim of this study was to assess the accuracy of an IAP monitoring system compared to a reference standard, the CO2 insufflator, during laparoscopy. The second aim was to assess the changes in renal biomarker levels during and after increases in IAP through pneumoperitoneum. A prospective cohort study in patients undergoing laparoscopy at the University Medical Center Groningen. IAP measurements were performed with a urinary catheter using an IAP monitoring system (Accuryn® Monitoring System, Accuryn Medical) and compared to the pressure set at the CO2-insufflator system. Bland-Altman analysis was performed with accounting for repeated measures. Urine samples were collected at several time-points and Kidney Injury Molecule 1 (KIM-1), Tissue Inhibitor of Metalloproteinase 2 (TIMP-2), urinary Neutrophil Gelatinase-Associated Lipocalin (NGAL), Liver-type Fatty Acid-Binding Protein (L-FABP), and albumin-creatinine ratio were measured.

When Henry Beecher and colleagues first systematized CRT measurement in 1947, they recognized its potential as a rapid method to evaluate circulatory status in trauma casualties, establishing a foundational framework that would influence intensive care practice for decades to come. However, clinicians soon discovered that relying on visual inspection alone introduced troubling variability between observers and even within the same observer's assessments, with expertise and training significantly influencing measurement accuracy. This recognition of CRT's limitations sparked a concerted effort to transform the measurement from a purely subjective exercise into a standardized, objective clinical tool. Researchers systematically refined protocols by establishing consistent pressure application techniques, standardized measurement sites, and defined normal thresholds (approximately 3 s for healthy adults). These methodological advances set the stage for rigorous clinical validation. Subsequent research revealed that CRT correlated powerfully with microvascular blood flow and independently predicted mortality and organ dysfunction in septic patients. Meta-analyses encompassing over 60,000 patients confirmed that abnormal CRT carried substantially elevated mortality risk, particularly when measured using standardized techniques. More recently, the ANDROMEDA-SHOCK trials demonstrated that CRT could serve not merely as a prognostic marker but as an actionable resuscitation target.

We evaluated whether associations between corticosteroid timing and clinical outcomes differed by hemodynamic trajectory phenotype defined by dynamic time warping clustering of Blood Pressure-Vasopressor Index (BPRI) trajectories across three ICU cohorts. We conducted a retrospective cohort study using MIMIC-IV as the derivation cohort and eICU-CRD and PINES as validation cohorts. Adult patients with septic shock receiving vasopressors were included. Hemodynamic phenotypes were identified from 168-h BPRI trajectories. Corticosteroid timing was classified as early (≤ 6 h) or late (> 6 h) after sepsis onset. In MIMIC-IV, inverse probability of treatment weighting with cause-specific Cox regression was used to estimate associations between timing and 28-day mortality, hospital length of stay, and ventilation duration within each phenotype. Validation cohorts were analyzed using multivariable Cox regression, and cohort-specific estimates were summarized using random-effects meta-analysis with I2. Two phenotypes were identified in MIMIC-IV: Deteriorated (N=2,082, 38%), with declining hemodynamics and higher mortality, and Improved (N=3,361, 62%), with stable or rising trajectories. Similar trajectory patterns were observed in eICU-CRD and PINES. In the Deteriorated phenotype, late corticosteroids were associated with lower 28-day mortality in MIMIC-IV (HR 0.88 [0.78-0.98]) and shorter ventilation duration (HR 0.65 [0.58-0.73]) compared with early administration. The mortality association was not consistently replicated in validation cohorts, whereas the ventilation association was observed in PINES Deteriorated patients. In the Improved phenotype, late steroids showed no consistent mortality or hospital length-of-stay association. Exploratory hemodynamic response analysis showed a more favorable BPRI slope for late versus early steroids in the Deteriorated phenotype. Hemodynamic trajectory phenotypes identified clinically meaningful variation in the relationship between corticosteroid timing and outcomes in septic shock. In the Deteriorated phenotype, delayed corticosteroid initiation was associated with lower 28-day mortality and shorter recovery, whereas the Improved phenotype showed no mortality advantage from delayed treatment.
