ABSTRACT

Objective:To evaluate the relationship between early postoperative recovery and frailty after digestive endoscopy-assisted minimally invasive surgery under intravenous anesthesia in the elderly.Methods:This study retrospectively selected hospitalized patients, aged ≥65 yr, scheduled for elective gastrointestinal endoscopic treatment.Early postoperative recovery time was defined as the period from the end of propofol administration to the achievement of a modified Aldrete score of 9.All the patients were divided into 2 groups according to whether the early recovery time after operation was less than 75%: normal early postoperative recovery time group and delayed early postoperative recovery time group.Frailty was assessed using the frailty phenotype (FP score 0-5), and the patient was diagnosed as frail (FP ≥3) or non-frail (FP 0-2). The age, sex, height, weight, smoking history, American Society of Anesthesiologists (ASA) Physical Status classification, type of operation, and baseline mean arterial pressure and heart rate were recorded.Logistic regression analysis was used to identify the risk factors for delayed early postoperative recovery time after minimally invasive digestive endoscopy under intravenous anesthesia in elderly patients.Results:A total of 214 patients were enrolled and divided into normal early postoperative recovery time group ( n=169) and delayed early postoperative recovery time group ( n=45). There were significant differences in frailty, age, drinking history of more than 10 yr, preoperative ASA Physical Status classification and propofol administration time between delayed early postoperative recovery time group and normal early postoperative recovery time group ( P<0.05). The results of logistic regression analysis indicated that frailty, age, ASA Physical Status classification Ⅲ, and propofol administration time were independent risk factors for the occurrence of delayed early postoperative recovery ( P<0.05). Conclusions:Frailty, age, ASA Physical Status classification Ⅲ and propofol administration time are independent risk factors for delayed early postoperative recovery time following digestive endoscopy-assisted minimally invasive surgery under intravenous anesthesia in elderly patients.

ABSTRACT

Objective:To analyze the key genes and mechanisms of sepsis secondary to multiple trauma based on bioinformatics methods.Methods:Data set GSE70311 was downloaded from Gene Expression Omnibus database.After data set pretreatment, differentially expressed genes (DEGs) in peripheral blood of patients with sepsis secondary to multiple injuries were screened using Limma R package.ClusterProfiler R package was used for gene ontology (GO) enrichment analysis and Kyoto encyclopedia of genes and genomes (KEGG) signaling pathway analysis of DEGs.Finally, the protein-protein interaction network was constructed by using the STRING online database and Cytoscape, and the hub genes of sepsis secondary to multiple injuries were identified based on Cytohubba.Results:In the GSE70311 dataset, 328 DEGs were obtained.The results of GO enrichment analysis showed that the biological processes involved in DEGs in sepsis secondary to multiple trauma mainly included T cell differentiation, positive regulation of cytokine production, defense response to bacteria, response to virus and defense response to virus, etc.The results of KEGG pathway enrichment analysis showed that DEGs were significantly enriched in hematopoietic cell lineage, Staphylococcus aureus infection, asthma, Th1 and Th2 cell differentiation, and antigen processing and presentation etc.signaling pathways in sepsis secondary to multiple trauma.Five hub genes were further screened by protein-protein interaction analysis, including STAT1, IFIT3, ISG15, IFIT1 and MX1. Conclusions:STAT1, IFIT3, ISG15, IFIT1 and MX1 are potential hub genes of sepsis secondary to multiple trauma, involved in T cell differentiation, positive regulation of cytokine production and defense response to pathogenic microorganisms, and enriched in Th1 and Th2 cell differentiation and antigen processing and presentation etc.signaling pathways.

ABSTRACT

Objective To investigate the effect of ultrasound-guided stellate ganglion block ( SGB) on perioperative inflammatory responses and postoperative recovery of gastrointestinal function in patients un-dergoing gastrointestinal surgery. Methods Fifty-five American Society of Anesthesiologists physical classⅠ-Ⅲpatients of both sexes, aged 18-64 yr, weighing 50-75 kg, undergoing elective gastrointestinal sur-gery, were divided into SGB group ( n=18) and control group ( C group, n=37) using a random number table method. Ultrasound-guided SGB was conducted with 0. 5% ropivocaine 7 ml at the left C6 level in SGB group. The equal volume of normal saline was given under ultrasound guidance at the same site in C group. Peripheral venous blood samples were collected at 5 min before SGB and 2, 4 and 24 h after SGB for deter-mination of plasma tumor necrosis factor-α ( TNF-α) , interleukin ( IL)-1β and IL-6 concentrations by en-zyme-linked immunosorbent assay. The increased level of leukocyte count ( leukocyte count at 24 h after SGB-leukocyte count at 24 h before SGB) was recorded. The recovery time of bowel sounds and anal or sto-ma exhaust time were also recorded. Results Compared with C group, the concentrations of TNF-αat 2 h after SGB and IL-1βat 2, 4 and 24 h after SGB were significantly decreased, the increased level of leuko-cyte count was decreased, and the recovery time of bowel sounds and anal or stoma exhaust time were short-ened in SGB group ( P<0. 05) . Conclusion Ultrasound-guided SGB can reduce perioperative inflammato-ry responses and promote the recovery of postoperative gastrointestinal function in the patients undergoing gastrointestinal surgery.

ABSTRACT

Objeoctive To compare the effects of etomidate and propofol on cerebral oxygen metabolism in patients undergoing abdominal surgery.Methods Thirty-six ASA Ⅰ or Ⅱ patients aged 30-64 yr weighing 42-73 kg undergoing abdominal surgery under general anesthesia were randomly divided into 2 groups (n=18 each):group E etomidate and group P propofol.Left radial artery was cannulated for continuous direct BP monitoring.A catheter was inserted into right internal jugular vein(LJV) and advanced cephalad until jngatar bulb for blood sampling.Both groups received midazolam 0.08 ms/ks,fentanyl 3μg/kg and vecurunium 0.1 mg/kg and in addition group P received propofol 1.5 mg/ks and group E etomidate 0.3 mg/kg respectively for induction of anesthesia.Anesthesia was maintained with propofol infusion at 4-6 mg·kg-1·h-1 in group P and etomidate infusion at 0.4-0.7 mg·kg-1·h-1 in group E and intermittent iv boluses of fentanyl and vecuronium.ECG,MAP,HR,SpO2 and PET CO2 were continuously monitored.Blood samples were taken from radial artery and IJV for blood gas analysis and lactic acid measurement before induction of anesthesia(T1),immediately after intubation (T2),30 min after skin incision (T3) and at the end of operation(T4).The rate of cerebral O2 extraction (CERO2) was calculated.Results The hemodynamic variables were within the normal range throughout the anesthesia and operation.The oxygen saturation and oxygen partial pressure of both arterial and venous blood(SaO2,SjvO2,PaO2,PjvO2) rose significantly after induction of anesthesia in both groups.There was no significant difference in arterial and venous blood lactic acid level and SaO2,SjvO2,CaO2,CjvO2,Da-jvO2 or CERO2 at all time points between the two groups.Conclusion Both etomidate and propofol combined with midazolam and fentanyl can decrease cerebral O2 metabolic rate and there is no significant difference between the two groups.

ABSTRACT

Objective To investigate the correlation between gene polymorphism within human β defensin 1 (DEFB1) and fungal susceptibility to severe sepsis through case-control association study.Methods A total of211 patients with severe sepsis in ICU were enrolled in the present case control study. Sepsis in this study was diagnosed according to the definition of American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference in 1992 and 2002. Based on the development of fungal infection during ICU stay, all 211 patients were divided into fungal infection group (Group Ⅰ) and control group (Group C). Alleles and genotypes of-1816A/G, -390A/T, -52A/G, -44C/G and-20A/G within DEFB1 gene were assayed in all 211 patients by means of DNA direct sequencing, Allele-specific PCR amplifications or high-throughput site-specific TaqMan assay. Genetic analysis was employed to calculate the distribution frequency of haplotypes. The correlation between the genomic variations (allele,genotype and haplotype) and fungal infection was analyzed by Chi-square test or Fisher's exact test.Odds ratio (OR) was employed to reflect the correlation degree of genetic factor with fungal susceptibility to severe sepsis. Results Group Ⅰ enrolled 80 patients, of whom 43 pstients were male, at age of (60.81 ± 18.30) years. Group C enrolled 131 patients, of whom 80 patients were male, at mean age of (60.42 ± 17.03) years. No significant difference was found between two groups in aspect of gender and age (P>0.05). The genetic locus of -1816A/G, -390A/T, -52A/G, -44C/G and -20A/G of both groups were in agreement with Hardy Weinberg equilibrium. No significant difference was found between two groups in the distribution of allelic frequencies and genotype frequencies (P >0.05). No significant difference was found in the distribution frequency of four common haplotypes of the above five genetic locus such as AAACG, ATGCA, GTGGG and ATACG (all P > 0.05). Conclusions Genetic locus of -1816A/G, -390A/T, -52A/G, -44C/G and-20A/G within DEFB1 gene have no correction with fungal infections in severe sepsis, suggesting that DEFB1 gene polymorphism may not serve as a key genetic marker for the predisposition to fungal infection in severe sepsis.
