In earlier studies, the definition of PIH is solely based on different absolute or relative thresholds. However, the time-course (eg, how fast blood pressure drops during induction) is rarely incorporated, whereas it might represent the hemodynamic instability of a patient. We propose a comprehensive model to distinguish hemodynamically unstable from stable patients by combining blood pressure thresholds with the magnitude and speed of decline.METHODSThis prospective study included 375 adult elective noncardiac surgery patients. Noninvasive blood pressure was continuously measured between 5 minutes before up to 15 minutes after the first induction agent had been administered. An expert panel rated whether the patient experienced clinically relevant hemodynamic instability or not. Interrater correlation coefficient and intraclass correlation were computed to check for consistency between experts. Next, an automated classification model for clinically relevant hemodynamic instability was developed using mean, maximum, minimum systolic, mean, diastolic arterial blood pressure (SAP, MAP, and DAP, respectively) and their corresponding time course of decline. The model was trained and tested based on the hemodynamic instability labels provided by the experts.RESULTSIn total 78 patients were classified as having experienced hemodynamic instability and 279 as not. The hemodynamically unstable patients were significantly older (7 years, 95% confidence interval (CI), 4-11, P < .001), with a higher prevalence of chronic obstructive pulmonary disease (COPD) (3% higher, 95% CI, 1-8, P = .036). Before induction, hemodynamically unstable patients had a higher SAP (median (first-third quartile): 161 (145-175) mm Hg vs 150 (134-166) mm Hg, P < .001) compared to hemodynamic stable patients. Interrater agreement between experts was 0.92 (95% CI, 0.89-0.94). The random forest classifier model showed excellent performance with an area under the receiver operating curve (AUROC) of 0.96, a sensitivity of 0.84, and specificity of 0.94.CONCLUSIONSBased on the high sensitivity and specificity, the developed model is able to differentiate between clinically relevant hemodynamic instability and hemodynamic stable patients. This classification model will pave the way for future research concerning hemodynamic instability and its prevention.","PeriodicalId":7799,"journal":{"name":"Anesthesia & Analgesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this randomized controlled trial was to evaluate the impact of remimazolam versus propofol on blood pressure changes during the therapeutic ERCP procedure.METHODSAdult patients scheduled for elective therapeutic ERCP were randomized to receive either remimazolam or propofol anesthesia (40 patients in each group). The primary outcomes included the change in mean arterial pressure (MAP) during induction and the area under the baseline (AUB), calculated as the blood pressure below baseline multiplied by the duration, throughout the procedure. These measures, respectively, indicated the severity of blood pressure decrease during anesthesia induction and the overall impact of blood pressure changes throughout the procedure. Any incidences of hypotension, defined as MAP <65 mm Hg for at least 1 minute, were recorded. The recovery time and any adverse events were also reported.RESULTSThe change in MAP after induction was smaller in the remimazolam group compared to the propofol group (-7.5 [-14.0 to 0] mm Hg vs -25.0 [-33.8 to -14.3] mm Hg), with a median difference of 17.0 mm Hg (95% confidence interval [CI], 12.0-22.0; P <.001). The AUB in the remimazolam group was less than in the propofol group (-373 [-82 to -854] mm Hg·min vs -705 [-272 to -1100] mm Hg·min), with a median difference of 255 mm Hg·min (95% CI, 29-477; P =.021). The incidence of hypotension was significantly lower for remimazolam than propofol (5% vs 30%; P =.006).

A systematic review of MEDLINE and Embase databases was performed. After screening of titles, abstracts, and full text, data were extracted from included studies. A pairwise meta-analysis of neuroprotective efficacy was performed using a random effects model. Heterogeneity was investigated using subgroup analysis, funnel plot asymmetry, and Egger's regression. The protocol was prospectively registered on PROSPERO (CRD42022301986). A total of 21 studies met the inclusion criteria. The data extracted included measurements from 1591 animals, involving models of HIE in mice, rats, and pigs. The meta-analysis found that both xenon and argon had significant (P < .0001) neuroprotective efficacies. The summary estimate for xenon was 39.7% (95% confidence interval [CI], 28.3%-51.1%) and for argon it was 70.3% (95% CI, 59.0%-81.7%).

In light of the opioid epidemic, MMA use has increased rapidly over the past decade. We hypothesize that the rapid adoption of MMA has resulted in variation in practice. This cross-sectional study aimed to determine how MMA practices have changed over the past 6 years and whether there is variation in use by patient, provider, and facility characteristics.METHODSOur study population includes all patients undergoing surgery with general anesthesia at 1 of 6 geographically similar hospitals in the United States between January 1, 2017 and December 31, 2022. Intraoperative pain medications were obtained from the hospital's perioperative information management system. MMA was defined as an opioid plus at least 2 other nonopioid analgesics. Frequencies, χ2 tests (χ2), range, and interquartile range (IQR) were used to describe variation in MMA practice over time, by patient and procedure characteristics, across hospitals, and across anesthesiologists. Multivariable logistic regression was conducted to understand the independent contributions of patient and procedural factors to MMA use.RESULTSWe identified 25,386 procedures among 21,227 patients. Overall, 46.9% of cases met our definition of MMA. Patients who received MMA were more likely to be younger females with a lower comorbidity burden undergoing longer and more complex procedures that included an inpatient admission. MMA use has increased steadily by an average of 3.0% each year since 2017 (95% confidence interval =2.6%-3.3%). There was significant variation in use across hospitals (n = 6, range =25.9%-68.6%, χ2 = 3774.9, P < .001) and anesthesiologists (n = 190, IQR =29.8%-65.8%, χ2 = 1938.5, P < .001), as well as by procedure characteristics. The most common MMA protocols contained acetaminophen plus regional anesthesia (13.0% of protocols) or acetaminophen plus dexamethasone (12.2% of protocols). During the study period, the use of opioids during the preoperative or intraoperative period decreased from 91.4% to 86.0% of cases; acetaminophen use increased (41.9%-70.5%, P < .001); dexamethasone use increased (24.0%-36.1%, P < .001) and nonsteroidal anti-inflammatory drugs (NSAIDs) increased (6.9%-17.3%, P < .001). Gabapentinoids and IV lidocaine were less frequently used but also increased (0.8%-1.6% and 3.4%-5.3%, respectively, P < .001).CONCLUSIONSIn a large integrated US health care system, approximately 50% of noncardiac surgery patients received MMA. Still, there was wide variation in MMA use by patient and procedure characteristics and across hospitals and anesthesiologists. Our findings highlight a need for further research to understand the reasons for these variations and guide the safe and effective adoption of MMA into routine practice.","PeriodicalId":7799,"journal":{"name":"Anesthesia & Analgesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monocyte epigenetic alterations leading to immune tolerance could explain postoperative increased susceptibility to infections. This research explores whether changes in monocyte DNA accessibility contribute to postoperative innate immune dysregulation.METHODSDamage-associated molecular patterns (DAMPs) and ex vivo cytokine production capacity were measured in a randomized controlled trial (n = 100) in colorectal surgery patients, with additional exploratory subgroup proteomic (proximity extension assay; Olink) and epigenomic analyses (Assay for Transposase-Accessible Chromatin [ATAC sequencing]). Monocytes of healthy volunteers were used to study the effect of high-mobility group box 1 (HMGB1) and heat shock protein 70 (HSP70) on cytokine production capacity in vitro.RESULTSPlasma DAMPs were increased after surgery. HMGB1 showed a mean 235% increase from before- (preop) to the end of surgery (95% confidence interval [CI] [166 - 305], P < .0001) and 90% increase (95% CI [63-118], P = .0004) preop to postoperative day 1 (POD1). HSP70 increased by a mean 12% from preop to the end of surgery (95% CI [3-21], not significant) and 30% to POD1 (95% CI [18-41], P < .0001). Nuclear deoxyribonucleic acid (nDNA) increases by 66% (95% CI [40-92], P < .0001) at the end of surgery and 94% on POD1 (95% CI [60-127], P < .0001). Mitochondrial DNA (mtDNA) increases by 370% at the end of surgery (95% CI [225-515], P < .0001) and by 503% on POD1 (95% CI [332-673], P < .0001). In vitro incubation of monocytes with HSP70 decreased cytokine production capacity of tumor necrosis factor (TNF) by 46% (95% CI [29-64], P < .0001), IL-6 by 22% (95% CI [12-32], P = .0004) and IL-10 by 19% (95% CI [12-26], P = .0015). In vitro incubation with HMGB1 decreased cytokine production capacity of TNF by 34% (95% CI [3-65], P = .0003), interleukin 1β (IL-1β) by 24% (95% CI [16-32], P < .0001), and IL-10 by 40% (95% CI [21-58], P = .0009). Analysis of the inflammatory proteome alongside epigenetic shifts in monocytes indicated significant changes in gene accessibility, particularly in inflammatory markers such as CXCL8 (IL-8), IL-6, and interferon-gamma (IFN-γ). A significant enrichment of interferon regulatory factors (IRFs) was found in loci exhibiting decreased accessibility, whereas enrichment of activating protein-1 (AP-1) family motifs was found in loci with increased accessibility.CONCLUSIONSThese findings illuminate the complex epigenetic modulation influencing monocytes' response to surgical stress, shedding light on potential biomarkers for immune dysregulation. Our results advocate for further research into the role of anesthesia in these molecular pathways and the development of personalized interventions to mitigate immune dysfunction after surgery.","PeriodicalId":7799,"journal":{"name":"Anesthesia & Analgesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cerebral desaturation is considered as one of the factors associated with burst suppression. Our study investigates the association between cerebral desaturation and burst suppression by analyzing their concurrence. Additionally, we aim to examine their association with cardiac surgical phases to identify potential for targeted interventions.METHODSWe retrospectively analyzed intraoperative 1-minute interval observations in 51 patients undergoing cardiac surgery. Processed EEG and cerebral oximetry were collected, with the anesthesiologists blinded to the information. The associations between cerebral desaturation (defined as a 10% decrease from baseline) and burst suppression, as well as with phase of cardiac surgery, were analyzed using the Generalized Logistic Mixed Effect Model. The results were presented as odds ratio and 95% confidence intervals (CIs). A value of P < .05 was considered statistically significant.RESULTSThe odds of burst suppression increased 1.5 times with cerebral desaturation (odds ratio [OR], 1.52, 95% CI, 1.11-2.07; P = .009). Compared to precardiopulmonary bypass (pre-CPB), the odds of cerebral desaturation were notably higher during CPB (OR, 22.1, 95% CI, 12.4-39.2; P < .001) and post-CPB (OR, 18.2, 95% CI, 12.2-27.3; P < .001). However, the odds of burst suppression were lower during post-CPB (OR, 0.69, 95% CI, 0.59-0.81; P < .001) compared to pre-CPB. Compared to pre-CPB, the odds of concurrent cerebral desaturation and burst suppression were notably higher during CPB (OR, 52.3, 95% CI, 19.5-140; P < .001) and post-CPB (OR, 12.7, 95% CI, 6.39-25.2; P < .001). During CPB, the odds of cerebral desaturation (OR, 6.59, 95% CI, 3.62-12; P < .001) and concurrent cerebral desaturation and burst suppression (OR, 10, 95% CI, 4.01-25.1; P < .001) were higher in the period between removal of aortic cross-clamp and end of CPB. During the entire surgery, the odds of burst suppression increased 8 times with higher inhalational anesthesia concentration (OR, 7.81, 95% CI, 6.26-9.74; P < .001 per 0.1% increase).CONCLUSIONSCerebral desaturation is associated with intraoperative burst suppression during cardiac surgery, most significantly during CPB, especially during the period between the removal of the aortic cross-clamp and end of CPB. Further exploration with simultaneous cerebral oximetry and EEG monitoring is required to determine the causes of burst suppression. Targeted interventions to address cerebral desaturation may assist in mitigating burst suppression and consequently enhance postoperative cognitive function.","PeriodicalId":7799,"journal":{"name":"Anesthesia & Analgesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
