Deep inhalation has been shown to enhance the variability of the internal jugular vein (IJV).

The existing Kidney Disease: Improving Global Outcomes (KDIGO) criteria do not specifically address acute-on-chronic kidney injury in this high-risk population. Previous studies have proposed alternative diagnostic thresholds that identify more AKI cases than KDIGO and are associated with adverse outcomes. However, their association with endpoints including mortality and clinical utility in cardiac surgery patients remain unclear. This study aims to explore optimal perioperative serum creatinine (SCr) change thresholds associated with in-hospital mortality and compare their predictive performance with KDIGO and other proposed thresholds.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This retrospective cohort study included 1,081 adult cardiac surgery patients with impaired preoperative kidney function (eGFR 15-60 mL/min/1.73 m²). Postoperative SCr changes were assessed as maximum absolute increases within 48 h and maximum fold increases within 7 days. Multivariable Cox regression and restricted cubic spline (RCS) analyses were used to evaluate associations with endpoints including in-hospital mortality, the initiation of KRT, failure of kidney function recovery by hospital discharge (or death), and major adverse kidney events (MAKE), defined as a composite of in-hospital mortality, dialysis dependence at discharge, or non-recovery of kidney function by hospital discharge (or death). Optimal thresholds were derived using receiver operating characteristic (ROC) curve analysis and Youden's index. The predictive performance and net clinical benefit for in-hospital mortality were compared across KDIGO definition, previously proposed thresholds, and the newly derived thresholds using ROC and decision curve analysis (DCA).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Both the absolute increase in SCr within 48 h and the fold increase within 7 days were independently associated with in-hospital mortality (HR 1.66 and 1.59, respectively), RRT (OR 3.10 and 3.62, respectively), kidney function non-recovery (OR 1.43 and 1.38, respectively), and MAKE (OR 2.32 and 2.24, respectively). For in-hospital mortality, the optimal thresholds identified were 38 µmol/L and 2.177-fold, respectively. ROC analysis showed comparable predictive performance with KDIGO definition and other standards. For in-hospital mortality, decision curve analysis suggested a marginally higher net benefit for the new thresholds within the 10-30% threshold probability range.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;This study proposes new SCr thresholds specific to cardiac surgery patients with impaired kidney function.

We used up-down sequential analysis to determine values of Ce&lt;sub&gt;prop&lt;/sub&gt; that produced an effective response in 50% of patients (EC&lt;sub&gt;50&lt;/sub&gt;). Probit analysis was applied as a backup and sensitivity test.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The calculated EC&lt;sub&gt;50&lt;/sub&gt; of propofol in nalbuphine Group of 0.2 mg·kg&lt;sup&gt;-1&lt;/sup&gt; (3.57 [95% CI 3.36 to 3.79] μg·ml&lt;sup&gt;-1&lt;/sup&gt;) were lower compared to propofol in nalbuphine Group of 0.15 mg·kg&lt;sup&gt;-1&lt;/sup&gt; (4.04 [95% CI 3.85 to 4.22] μg·ml&lt;sup&gt;-1&lt;/sup&gt;) and sufentanil Group of 0.15 μg·kg&lt;sup&gt;-1&lt;/sup&gt; (4.07 [95% CI 3.88 to 4.25] μg·ml&lt;sup&gt;-1&lt;/sup&gt;) (P = 0.002). Differences between EC&lt;sub&gt;50&lt;/sub&gt; values for propofol in nalbuphine Group of 0.15 mg·kg&lt;sup&gt;-1&lt;/sup&gt; and sufentanil Group of 0.15 μg·kg&lt;sup&gt;-1&lt;/sup&gt; were not statistically significant. Minutely propofol requirement was also lower in 0.2 mg·kg&lt;sup&gt;-1&lt;/sup&gt; nalbuphine Group (0.22 [0.19 to 0.27] mg·kg&lt;sup&gt;-1&lt;/sup&gt;·min&lt;sup&gt;-1&lt;/sup&gt;) compared with 0.15 mg·kg&lt;sup&gt;-1&lt;/sup&gt; nalbuphine Group (0.30 [0.25 to 0.33] mg·kg&lt;sup&gt;-1&lt;/sup&gt;·min&lt;sup&gt;-1&lt;/sup&gt;) and 0.15 μg·kg&lt;sup&gt;-1&lt;/sup&gt; sufentanil Group (0.27 [0.24 to 0.37] mg·kg&lt;sup&gt;-1&lt;/sup&gt;·min&lt;sup&gt;-1&lt;/sup&gt;) (P = 0.020).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;During hysteroscopic surgery, when compared with sufentanil, 0.2 mg·kg&lt;sup&gt;-1&lt;/sup&gt; nalbuphine significantly reduced the EC&lt;sub&gt;50&lt;/sub&gt; for propofol to inhibit cervical dilation response and the propofol requirement, and did not delay the emergence from anesthesia. Whether 0.2 mg·kg&lt;sup&gt;-1&lt;/sup&gt; nalbuphine could improve perioperative prognosis is worthy of further studies.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Trial registration: &lt;/strong&gt;The study was then registered on August 9th, 2023 at the Chinese Clinical Trial Registry which participates in the World Health Organization International Clinical Trials Registry Platform (Identifier: ChiCTR2300074513) before enrolling the first pa","PeriodicalId":9190,"journal":{"name":"BMC Anesthesiology","volume":"25 1","pages":"342"},"PeriodicalIF":2.3,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12232795/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144583122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
