ABSTRACT
AIMS: PD-1 block was reported to impair opioid-induced antinociception and affect cognitive function in rodents and non-human primates. This prospective multicenter cohort study aims to investigate the possible impact of neoadjuvant immunotherapy with PD-1 antibody on perioperative analgesic effect of opioids and postoperative delirium (POD) for non-small-cell lung cancer (NSCLC) patients. METHODS: Eighty-four NSCLC patients from three medical centers with neoadjuvant chemoimmunotherapy (nCIT) or chemotherapy (nCT) were enrolled. The primary outcome is the total perioperative opioid consumption defined as the sum of intraoperative and postoperative opioid use within 3 days after surgery. Secondary outcomes compromise of incidence of POD, pain intensity, and number of analgesic pump press. Tumor prognostic parameters and perioperative change of inflammatory cytokines and soluble PD-L1 level were also recorded. RESULTS: Eighty-one patients were included in the final analysis. The total opioid consumption (sufentanil equivalent) perioperatively in the nCIT group was significantly higher than that in the nCT group, with mean difference of 60.39 µg, 95% CI (25.58-95.19), p < 0.001. Multiple linear regression analysis showed that nCIT was correlated with increased total opioid consumption (ß = 0.305; 95% CI, 0.152-0.459; p < 0.001). The incidence of moderate-to-severe pain and cumulative analgesic pump press within 72 h was significantly higher in subjects with nCIT. There is no statistical difference in incidence of POD between groups within 72 h after surgery. The pathologic complete response rate and perioperative serum IL-6 level were higher in the nCIT group than in the nCT group. CONCLUSION: Patients with NSCLC receiving nCIT warrant increased opioid consumption perioperatively and suffered from more postoperative pain. CLINICAL TRIAL REGISTRATION: NCT05273827.

BACKGROUND: High doses of long-acting opioids were used to facilitate off-pump coronary artery bypass grafting procedure, which may result in opioid-related adverse events after surgery. Transcutaneous electrical acupoint stimulation (TEAS) had been reported to be effective in reducing intraoperative opioids consumption during surgery. The aim of this study is to assess whether TEAS with difference acupoints can reduce the doses of opioid analgesics. METHODS: This was a multicenter, randomized, controlled, double-blind trial. Patients underwent off-pump coronary artery bypass grafting under general anesthesia were enrolled. Eligible patients were randomly and equally grouped into sham acupuncture group (n = 105), regional acupoints combination group (n = 105), or distal-proximal acupoints combination group (n = 105) using a centralized computer-generated randomization system. Transcutaneous electrical acupoint stimulation was applied for 30 min before anesthesia induction. The primary outcome was the doses of sufentanil during anesthesia. Secondary outcomes included the highest postoperative vasoactive-inotropic scores within 24 h, intraoperative propofol consumption, length of mechanical ventilation, duration of cardiac care unit and postoperative hospital stay, incidence of postoperative complications, and mortality within 30 days after surgery. RESULTS: Of the 315 randomized patients, 313 completed the trial. In the modified intention-to-treat analysis, the doses of sufentanil were 303.9 (10.8) µg in the distal-proximal acupoints group, significantly lower than the sham group, and the mean difference was - 34.9 (- 64.9 to - 4.9) µg, p = 0.023. The consumption of sufentanil was lower in distal-proximal group than regional group (303.9 vs. 339.5), and mean difference was - 35.5 (- 65.6 to - 5.5) µg, p = 0.020. The distal-proximal group showed 10% reduction in opioids consumption comparing to both regional and sham groups. Secondary outcomes were comparable among three groups. CONCLUSION: Transcutaneous electrical acupoint stimulation with distal-proximal acupoints combination, compared to regional acupoints combination and sham acupuncture, significantly reduced sufentanil consumption in patients who underwent off-pump coronary artery bypass grafting surgery.
ABSTRACT
Background: Compared with cardiopulmonary bypass surgery, off-pump coronary artery bypass grafting (OPCABG) reduces trauma to the body. However, there is still a risk of neurological complications, including postoperative delirium (POD). To date, few studies have been conducted on the risk of POD in OPCABG patients, and no standardized prediction model has been established. Thus, this study sought to analyze the factors influencing POD in OPCABG patients and to construct a risk prediction model. Methods: A total of 1,258 patients with OPCABG were enrolled and divided into the training set for model construction (944 cases) and the test set for model validation (314 cases). A risk prediction model for POD in OPCABG patients was established by least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression, and a nomogram was drawn. The discrimination and calibration degree of the model was evaluated by the receiver operator characteristic (ROC) curve and calibration curve. Results: Eight variables [i.e., age, tissue oxygen saturation, mean arterial pressure (MAP), carotid stenosis, the anterior-posterior diameter of the aortic sinus, ventricular septum thickness, left ventricular ejection fraction (LVEF), and Mini-Mental State Examination (MMSE) scores] were screen out by the LASSO regression and multivariate logistic regression, and the model was constructed. The area under the ROC curve of the training set was 0.702 [95% confidence interval (CI): 0.662-0.743], and that of the test set was 0.658 (95% CI: 0.585-0.730). The results of the Hosmer-Lemeshow goodness-of-fit test showed that the predicted POD risk of OPCABG patients in the training and test sets was consistent with the actual POD risk (χ2=5.154, P=0.74). Conclusions: The occurrence of POD in OPCABG patients is related to age, tissue oxygen saturation, MAP, carotid artery stenosis, the anterior-posterior diameter of aortic sinus, ventricular septal thickness, LVEF, and MMSE scores. The prediction model constructed with the above variables had high predictive performance, and thus may be helpful in the early identification of such patients.
ABSTRACT
Sepsis is a syndrome characterized by a systemic inflammatory response due to the invasion of pathogenic microorganisms. The relationship between Lipocalin-2 (LCN2), elastase, neutrophil expressed (ELANE) and sepsis remains unclear. The sepsis datasets GSE137340 and GSE154918 profiles were downloaded from gene expression omnibus generated from GPL10558. Batch normalization, differentially expressed Genes (DEGs) screening, weighted gene co-expression network analysis (WGCNA), functional enrichment analysis, Gene Set Enrichment Analysis (GSEA), immune infiltration analysis, construction and analysis of protein-protein interaction (PPI) networks, Comparative Toxicogenomics Database (CTD) analysis were performed. Gene expression heatmaps were generated. TargetScan was used to screen miRNAs of DEGs. 328 DEGs were identified. According to Gene Ontology (GO), in the Biological Process analysis, they were mainly enriched in immune response, apoptosis, inflammatory response, and immune response regulation signaling pathways. In cellular component analysis, they were mainly enriched in vesicles, cytoplasmic vesicles, and secretory granules. In Molecular Function analysis, they were mainly concentrated in hemoglobin binding, Toll-like receptor binding, immunoglobulin binding, and RAGE receptor binding. In Kyoto Encyclopedia of Genes and Genomes (KEGG), they were mainly enriched in NOD-like receptor signaling pathway, Toll-like receptor signaling pathway, TNF signaling pathway, P53 signaling pathway, and legionellosis. Seventeen modules were generated. The PPI network identified 4 core genes (MPO, ELANE, CTSG, LCN2). Gene expression heatmaps revealed that core genes (MPO, ELANE, CTSG, LCN2) were highly expressed in sepsis samples. CTD analysis found that MPO, ELANE, CTSG and LCN2 were associated with sepsis, peritonitis, meningitis, pneumonia, infection, and inflammation. LCN2 and ELANE are highly expressed in sepsis and may serve as molecular targets.

At present, there is no relevant expert consensus indicating which ventilation device is more efficient for general anesthesia. The present literature review and meta-analysis compared the effects of the laryngeal mask airway and endotracheal intubation on airway complications during general anesthesia. The keywords 'laryngeal mask airway', 'endotracheal tube', 'tracheal tube', 'children', 'pediatric', 'anesthesia', 'randomized controlled trials' (RCTs) and 'randomized' were used to perform the literature search in PubMed. Quality assessment was performed by two reviewers according to domains defined by the Cochrane Collaboration tool. Data extraction, risk of bias assessment and quality of evidence assessment were performed with the Cochrane tool. A total of 16 RCTs were included. The results indicated that the effects of the laryngeal mask airway group on heart rate variability [mean difference=-13.76; 95% CI, -18.19-(-9.33); P<0.00001], the incidence of hypoxemia [odds ratio (OR)=0.52; 95% CI, 0.28-0.97; P=0.04] and the incidence of postoperative cough (OR=0.22; 95% CI, 0.12-0.40; P<0.0001) were significantly lower than those of the endotracheal intubation group. The success rate of one-time implantation in the laryngeal mask airway group was significantly higher than that noted in the endotracheal intubation group (OR=0.20; 95% CI, 0.07-0.59; P=0.003). However, no significant differences were noted between the two groups in bronchospasm, sore throat, mucosal injury, nausea and vomiting and reflux aspiration. In conclusion, the results indicated that laryngeal mask airway application can reduce complications during general anesthesia compared with endotracheal intubation.
ABSTRACT
OBJECTIVE: Postoperative pulmonary complications are a series of disorders that can contribute to respiratory distress and prolonged mechanical ventilation postoperatively. We hypothesise that a liberal oxygenation strategy during cardiac surgery leads to a higher incidence of postoperative pulmonary complications than a restrictive oxygenation strategy. METHODS: This study is a prospective, observer-blinded, centrally randomised and controlled, international multicentre clinical trial. RESULTS: After obtaining a written informed consent, 200 adult patients undergoing coronary artery bypass grafting will be enrolled and randomised to receive either restrictive or liberal oxygenation perioperatively. The liberal oxygenation group will receive 1.0 fraction of inspired oxygen throughout the intraoperative period, including during cardiopulmonary bypass. The restrictive oxygenation group will receive the lowest fraction of inspired oxygen required to maintain arterial partial pressure of oxygen between 100 and 150 mmHg during cardiopulmonary bypass and a pulse oximetry reading of 95% or greater intraoperatively, but no less than 0.3 and not higher than 0.80 (other than induction and when the oxygenation goals cannot be reached). When patients are transferred to the intensive care unit, all patients will receive an initial fraction of inspired oxygen of 0.5, and then fraction of inspired oxygen will be titrated to maintain a pulse oximetry reading of 95% or greater until extubation. The lowest postoperative arterial partial pressure of oxygen/fraction of inspired oxygen within 48 hours of intensive care unit admission will be the primary outcome. Postoperative pulmonary complications, length of mechanical ventilation, intensive care unit stay, hospital stay, and 7-day mortality after cardiac surgery will be analysed as secondary outcomes. CONCLUSION: This is one of the first randomised controlled observer-blinded trials that prospectively evaluates the influence of higher inspired oxygen fractions on early postoperative respiratory and oxygenation outcomes in cardiac surgery patients using cardiopulmonary bypass.
ABSTRACT
Background: Multiple organ failure (MOF) is the main cause of early death in septic shock. Lungs are among the organs that are affected in MOF, resulting in acute lung injury. A large number of inflammatory factors and stress injury in sepsis can lead to alterations in mitochondrial dynamics. Numerous studies have confirmed that hydrogen can alleviate sepsis in the animal model. The purpose of this experiment was to explore the therapeutic effect of high concentration (67%) hydrogen on acute lung injury in septic mice and its mechanism. Methods: The moderate and severe septic models were prepared by cecal ligation and puncture. Hydrogen with different concentrations was inhaled for one hour at 1 h and 6 h after the corresponding surgery. The arterial blood gas of mice during hydrogen inhalation was monitored in real time, and the 7-day survival rate of mice with sepsis was recorded. The pathological changes of lung tissues and functions of livers and kidneys were measured. The changes of oxidation products, antioxidant enzymes and pro-inflammatory cytokines in lungs and serums were detected. Mitochondrial function was measured. Results: The inhalation of 2% or 67% hydrogen improves the 7-day survival rate and reduces acute lung injury as well as liver and kidney injury in sepsis. The therapeutic effect of 67% hydrogen inhalation on sepsis was related to increasing antioxidant enzyme activity, reducing oxidation products and pro-inflammatory cytokines in lungs and serums. Compared with the Sham group, mitochondrial dysfunction was alleviated in hydrogen groups. Conclusions: Hydrogen inhalation by high or low concentration can both significantly improve sepsis; however, a high concentration demonstrates a better protective effect. High concentration hydrogen inhalation can significantly improve the mitochondrial dynamic balance and reduce the lung injury in septic mice.
ABSTRACT
Background: The neuroprotective effect of remote ischemic preconditioning (RIPC) in patients undergoing elective cardiopulmonary bypass (CPB)-assisted coronary artery bypass graft (CABG) or valvular cardiac surgery remains unclear. Methods: A randomized, double-blind, placebo-controlled superior clinical trial was conducted in patients undergoing elective on-pump coronary artery bypass surgery or valve surgery. Before anesthesia induction, patients were randomly assigned to RIPC (three 5-min cycles of inflation and deflation of blood pressure cuff on the upper limb) or the control group. The primary endpoint was the changes in S-100 calcium-binding protein ß (S100-ß) levels at 6 h postoperatively. Secondary endpoints included changes in Neuron-specific enolase (NSE), Mini-mental State Examination (MMSE), and Montreal Cognitive Assessment (MoCA) levels. Results: A total of 120 patients [mean age, 48.7 years; 36 women (34.3%)] were randomized at three cardiac surgery centers in China. One hundred and five patients were included in the modified intent-to-treat analysis (52 in the RIPC group and 53 in the control group). The primary result demonstrated that at 6 h after surgery, S100-ß levels were lower in the RIPC group than in the control group (50.75; 95% confidence interval, 67.08 to 64.40 pg/ml vs. 70.48; 95% CI, 56.84 to 84.10 pg/ml, P = 0.036). Compared to the control group, the concentrations of S100-ß at 24 h and 72 h and the concentration of NSE at 6 h, 24 h, and 72 h postoperatively were significantly lower in the RIPC group. However, neither the MMSE nor the MoCA revealed significant between-group differences in postoperative cognitive performance at 7 days, 3 months, and 6 months after surgery. Conclusion: In patients undergoing CPB-assisted cardiac surgery, RIPC attenuated brain damage as indicated with the decreased release of brain damage biomarker S100-ß and NSE. Clinical trial registration: [ClinicalTrials.gov], identifier [NCT01231789].
ABSTRACT
BACKGROUND: The ClearSight system measures blood pressure non-invasively and determines cardiac output by analyzing the continuous pressure waveform. We performed a multi-center clinical study in China to test the equivalence of cardiac output measured with the ClearSight system (CSCO) and cardiac output measured with the pulmonary artery catheter bolus thermodilution (TDCO) method. METHODS: We included adult patients undergoing cardiac surgery in three Chinese hospitals and measured TDCO and CSCO simultaneously after induction of anesthesia. Hemodynamic stability was required during measurement of TDCO and CSCO. At least four TDCO determinations were performed. The corresponding CSCO was determined as the average over a 30-s period following the injection of each bolus. A data pair for the comparison included the average of three or four accepted TDCO values and the average of the matching CSCO values. Main outcomes included Bland-Altman analysis of bias and standard deviation (SD) and the percentage error (PE). RESULTS: One hundred twenty-five subjects were enrolled, and 122 TDCO and CSCO data pairs were available for analysis. Ninety-five (75.4%) data pairs were collected in hemodynamically stable conditions, mean (SD) CSCO was 4.21 (0.78) l/min, and mean TDCO was 3.90 (0.67) l/min. Bias was 0.32 (0.51) l/min, and PE was 25.2%. Analyzing all 122 data pairs resulted in a mean CSCO of 4.19 (0.82) l/min and a mean TDCO of 3.83 (0.71) l/min. Resulting bias was 0.36 (0.53) l/min, and PE was 26.4%. CONCLUSIONS: CSCO and TDCO agreed with a low systematic bias. Besides, mean PE was well below the pre-defined 30%. Hemodynamic stability only had a small impact on the analysis. We conclude that CSCO is equivalent to TDCO in cardiac surgery patients. The trial was retrospectively registered in ClinicalTrials.gov, identifier NCT03807622 ; January 17, 2019.
ABSTRACT
PURPOSE: To study the feasibility and outcomes of ketamine as an anesthetic adjunct during monitored anesthesia care (MAC) in transcatheter aortic valve replacement (TAVR). DESIGN: This was a retrospective study. METHODS: Data from 155 consecutive TAVR patients at a tertiary care high-volume TAVR medical center were reviewed and analyzed. FINDINGS: Among the 155 TAVR cases under MAC, intravenous ketamine was administered as an adjunct in 126 patients. The most common ketamine dose was 20 mg. There was no significant difference for postoperative stroke, intraoperative conversion to general anesthesia, postoperative delirium, need for permanent pacemaker implantation, perivalvular leak and length of stay between the ketamine and non-ketamine groups. The ketamine group demonstrated a statistically significant lower 30-day mortality (P = .0381) and intraoperative cardiac arrest (P = .0025) rate when compared to the nonketamine group. CONCLUSIONS: Our results demonstrated that employing ketamine as an adjunct during MAC for TAVR is a feasible option.

BACKGROUND: The cardioprotective properties of sevoflurane have been reported in studies of the left ventricle. However, whether this volatile anesthetic would also be beneficial for pulmonary vascular remodeling and associated right ventricular hypertrophy (RVH) remained to be explored. Here, we investigated the potential benefit of sevoflurane to right heart function in experimental pulmonary arterial hypertension (PAH). METHODS: Adult Wistar rats received one dose peritoneal injection of monocrotaline (MCT, 60 mg/kg) or the equal volume of normal saline. Two weeks later, rats were treated with sevoflurane or sham exposure. PAH status and cardiac function were assessed by echocardiography weekly, and the body weight (BW) was monitored every week. After 6 weeks of exercise, Fulton's index calculation, histological observation, IL-6 and TNF-α immunohistochemical analyses, evaluation of MDA, SOD and GSH-Px levels and NF-κB and MAPK active determination were performed in lung and RV tissue samples. RESULTS: MCT induced pulmonary vascular remodeling, RVH, increased Fulton's index (P<0.01), and right ventricular failure (RVF) in rats. Animals inhaled sevoflurane had an increased cardiac output (P<0.05) and lower incidence of RVF (P<0.05). Also, these animals had a reduced RVEDD, RVWTd and PAID (P<0.05), increased PV (P<0.05), reduced wall thickness and vascular wall area of pulmonary small vascular (vascular external diameter 50-150 um) (P<0.01), reduced RV fibrosis, and increased RV cardiomyocyte area (P<0.01). Furthermore, sevoflurane reduced IL-6 and TNF-α expression in lungs and heart (P<0.01), decreased level of MDA (P<0.01) and increased activity of SOD and GSH-Px (P<0.01). In addition, it decreased the activities of NF-κB and MAPK pathways (P<0.01). CONCLUSION: Sevoflurane reduces pulmonary vascular remodeling and RVH in PAH induced by MCT in rats. This effect is likely due to down-regulation of inflammatory factors IL-6 and TNF-α, reduced level of oxidative stress and the inhibition of NF-κB and MAPK pathways.
ABSTRACT
BACKGROUND: Intraoperative hemodynamic collapse during transcatheter aortic valve implantation (TAVI) is a devastating complication that requires mechanical support. In this study, we sought to analyze our early experience in using cardiopulmonary bypass (CPB) support to circumvent circulatory compromise during TAVI. METHODS: Between January 2018 and December 2020, 102 consecutive patients (54 males; mean age, 71.2±8.9 years) received TAVI at Tianjin Chest Hospital, and an emergency CPB device was used in 6 of these patients (5.9%). The clinical data of the CPB and no-CPB groups were analyzed to identify the factors associated with intraoperative hemodynamic collapse requiring CPB. RESULTS: All 6 patients who needed emergency CPB support were successfully weaned from the device. This group had a higher Society of Thoracic Surgeons Score [4.09 (2.02, 6.85) vs. 7.47 (5.07, 23.46); P=0.030], more patients with a left ventricular ejection fraction (LVEF) ≤30% [4 (66.7%) vs. 2 (2.1%); P=0.000], a larger right ventricle anteroposterior diameter [20.50 (19.75, 21.25) vs.19.00 (17.00, 20.00); P=0.016], and a higher degree of aortic regurgitation [4.50 (2.75, 5.00) vs. 2.00 (1.00, 4.00); P=0.018] compared to the no-CPB group. The CPB group also had a higher in-hospital mortality rate than did the no-CPB group (16.7% vs. 4.7%; P=0.026). Multivariable analysis determined that the presence of lower pre-TAVI LVEF was associated with intraoperative hemodynamic collapse. CONCLUSIONS: Our results indicate that LVEF is an independent risk factor for requiring emergency CPB during the TAVI procedure. The need for emergency CPB support was associated with higher in-hospital mortality.
ABSTRACT
The aim of the present study was to determine the effect of dexmedetomidine on hemodynamic changes and inflammatory responses in patients undergoing off-pump coronary artery bypass grafting (OPCABG). A total of 300 patients about to receive OPCABG were randomized evenly into the control group (n=116) and study group (n=123). Intravenous dexmedetomidine pump infusion was administered to patients in the study group at a rate of 0.4 µg.kg-1.h-1. The control group received physiological saline at the same infusion speed. Changes in hemodynamic parameters and inflammatory indices were compared between the two groups. Hemodynamic parameters, such as the heart rate and mean arterial pressure, were lower in patients from the study group, compared with that in the control group (both P<0.05). The levels of pro-inflammatory factors, such as interleukin (IL)-6, tumor necrosis factor-α and C-reactive protein, were also reduced in the study group (P<0.05). The observed levels of IL-10 were lower in the control group compared with that in the study group, although a statistically significant difference was not achieved. Thus, the administration of dexmedetomidine in patients undergoing OPCABG stabilized hemodynamics and reduced inflammation. The present study was registered at the Chinese Clinical Trial Registry, under the trial registration number ChiCTR-OOC-15005978 (2015).
ABSTRACT
BACKGROUND: Bicuspid aortic valve (BAV) is common congenital malformation, bicuspid aortic stenosis accounts for a substantial proportion of patients with aortic valve stenosis (AS). Bicuspid AS are more likely to have aortic dilatation with slightly less elliptical annuli, which might lead to paravalvular aortic valve regurgitation (AR) and permanent pacemaker implantation (PPM) after TAVI with higher mortality. Our study aims to understand the therapeutic efficacy and safety of transcatheter aortic valve implantation (TAVI) with a supra-annular structure-based sizing strategy in Chinese AS patients with BAV versus tricuspid aortic valve (TAV). METHODS: Seventy-four consecutive tricuspid AS patients and 44 bicuspid AS patients were included and enrolled in the study for analysis. Both groups underwent TAVI performed using balloon sizing less than mild paravalvular AR to assess the proper prosthesis size. The myocardial function within 1 year postoperative were sequentially evaluated using the New York Heart Association (NYHA) class, and echocardiography measurements. The incidence rates of complications at 30 days and 1 year were analyzed. During the 1-year follow-up, the time of death from any cause or complications in both groups was recorded. RESULTS: The study found that the percentage of patients with class III-IV of NYHA dropped after TAVI in both groups, and no significant difference between both groups at 1 year. Compared with the tricuspid AS group patients, Bicuspid group patients had more improvement in mean aortic valve gradient from baseline to 1year (-47.47±13.38 vs. -50.22±19.25 mmHg, P<0.05). There were no significant differences in 30-day and one-year compliance outcomes except a lower incidence of AR at post-procedure and 30 days in the tricuspid AS group as the Bicuspid AS group. There were no statistically significant differences in the time of death from any cause or significant complications between groups. CONCLUSIONS: TAVI has acceptable therapeutic efficacy and safety and is feasible for AS patients with BAV in China.
ABSTRACT
Significance of intercellular adhesion molecule-1 (ICAM-1) and S-100ß protein (S-100ß) were investigated in sevoflurane combined with epidural anesthesia for radical resection of lung cancer. In total, 172 patients who underwent radical resection of lung cancer from May 2014 to January 2016 and 160 blood samples from healthy patients in the same period were selected for prospective analysis. Lung cancer patients were the therapy group (TG). Venous blood (2 ml) was taken from patients before anesthesia (T1) and after anesthesia at 30 min (T2), 3 h (T3) and 24 h (T4), respectively. Healthy physical examination samples were the control group (CG). Enzyme linked immunosorbent assay (ELISA) was used to detect the concentration of ICAM-1 and RT-PCR to detect the concentration of S-100ß. The changes of ICAM-1 and S-100ß concentrations and their significance to patients were analyzed. The serum ICAM-1 and S-100ß concentrations in TG were significantly higher than those in CG (P<0.001), and were the highest at T1 (P>0.001), followed by T2 (P<0.001). Of the 172 patients 27 cases had adverse complications during the perioperative period. Patients were divided into the ICAM-1 high concentration group (CHCG), the ICAM-1 low concentration group (CLCG) and the S-100ß high concentration group (SHCG) and the S-100ß low concentration group (SLCG). The 3-year survival rate of CHCG was significantly lower than CLCG and SLCG (P<0.001). ICAM-1 and S-100ß protein in sevoflurane combined with epidural anesthesia for radical resection of lung cancer can effectively predict the perioperative adverse complications of patients, and have better monitoring significance for the prognosis of patients.
ABSTRACT
OBJECTIVE: To perform a comprehensive nationwide survey of more than 90% of all cardiovascular hospitals in China to assess the current 2018 status of transesophageal echocardiography (TEE) equipment, operating physicians, education, impact on surgery, and reimbursement. DESIGN: In this nationwide survey, 716 cardiovascular hospitals in mainland China were included. A 15-question electronic survey was sent to these hospitals and the data were received directly from the questionnaire website for analysis. SETTING: Cardiovascular hospitals in mainland China. PARTICIPANTS: Departments of anesthesiology in cardiovascular hospitals in mainland China. INTERVENTIONS: Answer a 15-question survey. MEASUREMENTS AND MAIN RESULTS: About 90% of hospitals have acquired machines to perform TEEs with most of the machines controlled by the ultrasound department. Anesthesiologists performed intraoperative TEEs in 45% of the hospitals, but only 15% of the hospitals have anesthesiologists who have met the basic TEE training requirements. Most anesthesiologists (68%) believed TEE significantly contributed to patient care during cardiovascular surgeries. The overwhelming majority of surveyed hospital staff (93%) stated that they were planning to continue or start intraoperative TEE examinations in the future. CONCLUSION: Many hospitals in China have acquired equipment to perform intraoperative TEE examinations during cardiovascular surgeries. However, the number of anesthesiologists who can perform TEEs independently still is not adequate. Standardized trainings, a formal certification process, and governmental payment model changes must be provided to ensure high-quality TEE services and better surgical outcomes in China.

OBJECTIVE: To investigate the effects of etomidate and propofol on immune function in patients with lung adenocarcinoma. METHODS: Sixty patients who were scheduled for lung cancer surgery under general anesthesia were studied. The patients were randomly divided into an etomidate total intravenous anesthesia group (group E) and a propofol total intravenous anesthesia group (group P), with 30 cases in each group. RESULTS: Within group comparison: The percentage of CD4+ in the two groups was significantly reduced at 24 hours post-operation (T2) compared with the percentage before surgery, whereas the percentage of CD8+ was higher at T2. Between group comparison: The CD4+ percentage of group E was higher than that of group P (P < 0.05) at T2, whereas the CD8+ percentage was lower than that of group P (P < 0.05) at T1. CONCLUSION: Using etomidate for anesthesia has less of an effect on immune function in patients with lung adenocarcinoma.
ABSTRACT
The high incidence of postoperative cognitive dysfunction (POCD) after extracorporeal circulation has seriously affected the prognosis and quality of life. Its mechanism may involve the inflammatory response and oxidative stress,the excessive phosphorylation of tau protein, the decreased blood volume and oxygen in the cerebral cortex. Appropriate early warning indicators of POCD after the extracorporeal circulation should be chosen to facilitate the cross validation of the results obtained different technical approaches and thus promote the early diagnosis and treatment of POCD.

OBJECTIVES: To compare the therapeutic efficacy of recombinant human brain natriuretic peptide and prostaglandin E1 in the treatment of pulmonary hypertension after mitral valve replacement. METHODS: Sixty patients with postoperative pulmonary hypertension were divided randomly into 3 groups that received saline, prostaglandin E1, and natriuretic peptide infusions for 12 hours each. The hemodynamics data were monitored consecutively, and the levels of thromboxane A2 and cyclic guanosine monophosphate were detected pretreatment, after treatment, and 1 week after surgery. RESULTS: The arterial pressure, pulmonary arterial pressure, and pulmonary capillary wedge pressure decreased 1 hour after prostaglandin E1 treatment and rebounded after treatment discontinuation. The pulmonary arterial pressure and pulmonary capillary wedge pressure in the natriuretic peptide group decreased 3 hours after treatment; pulmonary arterial pressure decreased less than that of the prostaglandin group, and there was no evidence of hemodynamic rebound after treatment discontinuation. The natriuretic peptide had no significant effects on arterial pressure. In both the prostaglandin and natriuretic peptide groups, cyclic guanosine monophosphate increased after the treatment, which was even higher in the latter group. Prostaglandin E1 could lead to the decrease of thromboxane A2, which was not seen in the natriuretic peptide group. CONCLUSIONS: Both brain natriuretic peptide and prostaglandin E1 can effectively reduce pulmonary hypertension; however, natriuretic peptide has a slower and milder efficacy. The effects of these 2 drugs in reducing the pulmonary arterial pressure may be mediated through different pathways.
