The Effects of Sevoflurane vs. Propofol for Inflammatory Responses in Patients Undergoing Lung Resection: A Meta-Analysis of Randomized Controlled Trials.

ABSTRACT: Objective: Inflammatory cytokines are increased during one-lung ventilation in patients undergoing lung resection, and this increase can be fatal. Propofol and sevoflurane are the main anesthetics used for these patients. Unfortunately, there is no consensus on the best choice of an anesthetic agent concerning an inflammatory response in patients undergoing lung resection. This meta-analysis aimed to compare the effects of propofol and sevoflurane on the inflammatory response in patients undergoing lung resection. Methods: We searched electronic databases to identify randomized controlled trials comparing the effects of different anesthetics (sevoflurane vs. propofol) on the inflammatory response. The primary outcome concerned the concentration of systemic inflammatory cytokines. The secondary outcomes concerned the concentrations of inflammatory cytokines in the bronchoalveolar lavage (BAL) fluid from the dependent and independent lung. Random effects analysis of the meta-analyses were performed to synthesize the evidence and to assess the concentrations of inflammatory factors in the sevoflurane and propofol groups. Results: Eight trials involving 488 participants undergoing lung resection with one-lung ventilation were included. There was no significant difference in the concentrations of systemic interleukin (IL)-6, IL-10, or tumor necrosis factor α between the sevoflurane and propofol groups. Compared with the propofol group, BAL levels of IL-6 in the dependent ventilated lung were decreased in the sevoflurane group (three trials, 256 participants; standardized mean difference [SMD], -0.51; 95% confidence interval [CI], -0.90 to -0.11; p = 0.01; I ² = 46%). The BAL levels of IL-6 in the independent ventilated lung were also decreased by sevoflurane (four trials, 362 participants; SMD, -0.70; 95% [CI], -0.93 to -0.47; p < 0.00001; I ² = 0%). Conclusions: There was no difference in the systemic inflammatory response between the sevoflurane and propofol groups. However, compared with propofol, sevoflurane can reduce the local alveolar inflammatory response. Additional research is necessary to confirm whether the inflammatory response is direct or indirect.

Project description:BackgroundPropofol and sevoflurane are two commonly used perioperative anesthetics. Some studies have found that these anesthetic drugs affect tumorigenesis. Previous studies have mostly focused on in vitro experiments, and the specimens collected were mainly peripheral body fluids, lacking direct evidence of the impact of anesthetic drugs on human tissues. This study aimed to elucidate the effects of propofol and sevoflurane on lung cancer using next-generation sequencing through an in vivo experiment.MethodsPatients were randomly assigned to a group receiving either propofol or sevoflurane during surgery. Then, the patients' tumor and paired normal samples were collected and sequenced by next-generation sequencing. Differentially expressed genes (DEG) were analyzed by two statistical models, followed by cluster analysis, PCA, Gene Ontology, and KEGG pathway analysis. Candidate genes were confirmed by qRT-PCR.ResultsThe demographic data of the two study groups were not statistically significant. Through single-factor model analysis, 810 DEG in the propofol group and 508 DEG in the sevoflurane group were obtained. To better reflect the differential effects between propofol and sevoflurane while reducing the false-positive DEG, we used multifactor model analysis, which resulted in 124 DEG. In PCA and cluster analysis, four groups (propofol cancer group, propofol normal group, sevoflurane cancer group, sevoflurane normal group) were separated adequately, indicating the accuracy of the analysis. We chose seven significant pathways (cellular response to interleukin-1, chemokine-mediated signaling pathway, chemokine signaling pathway, cytokine-cytokine receptor interaction, inflammatory response, immune response, and TNF signaling pathway) for downstream analysis. Based on the pathway analysis, three candidate genes (CXCR1, CXCL8, and TNFAIP3) were chosen, and their qRT-PCR results were consistent with the sequencing results.ConclusionsThrough RNA-seq analysis, the effects of propofol and sevoflurane during lung cancer resection were different, mainly in inflammatory-related pathways, which might be possibly by targeting CXCL8.Trial registrationTrial registry number was ChiCTR1900026213 .

Project description:BackgroundThe purpose of this randomised, single-centre study was to prospectively investigate the impact of anaesthetic techniques for craniotomy on the release of cytokines IL-6, IL-8, IL-10, and to determine whether intravenous anaesthesia compared to inhalational anaesthesia attenuates the inflammatory response.MethodsThe study enroled 40 patients undergoing craniotomy, allocated into two equal groups to receive either sevoflurane (n = 20) or propofol (n = 20) in conjunction with remifentanil and rocuronium. The lungs were ventilated mechanically to maintain normocapnia. Remifentanil infusion was adjusted according to the degree of surgical manipulation and increased when mean arterial pressure and the heart rate increased by more than 30 % from baseline. The depth of anaesthesia was adjusted to maintain a bispectral index (BIS) of 40-60. Invasive haemodynamic monitoring was used. Serum levels of IL-6, IL-8 and IL-10 were measured before surgery and anaesthesia, during tumour removal, at the end of surgery, and at 24 and 48 h after surgery. Postoperative complications (pain, vomiting, changes in blood pressure, infection and pulmonary, cardiovascular and neurological events) were monitored during the first 15 days after surgery.ResultsCompared with patients anaesthetised with sevoflurane, patients who received propofol had higher levels of IL-10 (p = 0.0001) and lower IL-6/IL-10 concentration ratio during and at the end of surgery (p = 0.0001). Both groups showed only a minor response of IL- 8 during and at the end of the surgery (p = 0.57).ConclusionsPatients who received propofol had higher levels of IL-10 during surgery. Neither sevoflurane nor propofol had any significant impact on the occurrence of postoperative complications. Our findings should incite future studies to prove a potential medically important anti-inflammatory role of propofol in neuroanaesthesia.Clinical trial registrationIdentified as NCT02229201 at www.clinicaltrials.gov.

Project description:Background and aimTotal intravenous anesthesia (TIVA) has proven advantage over inhalational anesthesia in terms of stable hemodynamic, eco-friendly, and good recovery profile, but apprehension regarding adequate depth of anesthesia and intraoperative recall is still pertaining. This study aims to compare propofol-dexmedetomidine-based TIVA with sevoflurane-based inhalational anesthesia in modified radical mastectomy in terms of depth of anesthesia, intraoperative recall, recovery profile, and hemodynamic status.Settings and designThis prospective randomized controlled study was conducted at a tertiary care center over a time frame of 1 year.MethodologyIn this randomized controlled study, 100 patients were randomly distributed into two groups: TIVA (Group T) and inhalational anesthesia (Group I). Group T patients received injection dexmedetomidine: 1 μg.kg-1 over 10 min followed by 0.7 μg.kg-1.h-1 and injection propofol: 25-100 μg.kg-1.min-1. Ventilation was maintained with oxygen-air gas flow. In Group I, patients were ventilated with nitrous oxide-oxygen (50:50) and sevoflurane. Rest of anesthesia for both the groups was same. Primary objective was to achieve adequate depth of anesthesia as monitored by intraoperative bispectral index value (BIS, 40-60). Hemodynamic variables, recovery profile, and amount of individual anesthetic agent consumed were recorded for comparison between two groups. For comparison of scale variables between two groups, independent sample t-test for significant difference between two sample means has been followed.ResultsIntraoperative BIS and hemodynamic variables were comparable (P > 0.05). Emergence time was 5.10 min in the TIVA group versus 8.38 min in the inhalational group (P = 0.00). Modified Aldrete score was comparable in two groups (P > 0.05). Cost of TIVA agents consumed per patient was 40% lesser than inhalational agents.ConclusionTIVA maintains adequate depth of anesthesia along with stable hemodynamic and good recovery profile, at low cost in an eco-friendly manner.

Project description:The aim of the present study was to elucidate the influence of the anesthetics propofol and sevoflurane on gene expression in patients undergoing coronary artery bypass graft surgery (CABG) and to provide a basis for the selection of the appropriate anesthetic. The gene expression profiles of patients receiving one of the two anesthetics were analyzed prior to and following the induction of anesthesia. GSE4386 microarray data obtained from the Gene Expression Omnibus database was used to identify the differentially expressed genes (DEGs) by significance analysis of the microarray. The data set contained data regarding atrial tissue samples from 40 patients that underwent CABG, and that received either propofol (n=10) or sevoflurane (n=10) or were control subjects (n=20). The 20 control samples comprised the same patients prior to undergoing CABG. The Kyoto Encyclopedia of Genes and Genomes and Gene Ontology (GO) Enrichment Analysis was applied to the DEGs using the Database for Annotation, Visualization and Integration Discovery functional annotation bioinformatics microarray tool. A total of 242 and 560 DEGs were identified in the human atrial samples treated with propofol and sevoflurane, respectively. Among these, 116 upregulated DEGs and no downregulated DEGs were found to be unique to sevoflurane, while 10 upregulated and 212 downregulated DEGs were unique to propofol. The majority of the pathways that were significantly over-represented among the upregulated DEGs were associated with the immune response, such as Toll- and NOD-like receptors and Jak-STAT signaling pathways. GO enrichment analysis revealed that the downregulated DEGs unique to sevoflurane treatment were involved in the immune response and glucose metabolism, while the upregulated DEGs were associated with cellular ion homeostasis and epithelial cell development. Compared with propofol, sevoflurane appeared to exert a more marked effect on biological pathways, such as drug metabolism, glycolysis, cellular ion homeostasis and epithelial cell development.
