Active clinical trials for "Surgical Wound Infection"

This is a double blind randomized trial in which patients with colorectal cancer undergoing surgery will be selected to receive either a symbiotic formulation or placebo. The researchers will compare incidence of surgical site infection between the study groups.

There is a recent increase in incidence of surgical site infection after cardiac surgery in our hospital, in spite of specific measures taken concerning some aspects of the surgical procedures, targeting a better control of the classically known major risk factors of infections, in routine procedures involving a sternotomy such as coronary artery bypass graft, valvuloplasty, aortic surgery, or combined procedures. The first objective of this monocentric prospective cohort study, is to evaluate underestimated specific risk factors of surgical site infection, during the perioperative period, for patients undergoing cardiac surgery with sternotomy. Secondly, to estimate the specific risk associated with each class or micro-organisms responsible, and their profile of resistance. The outcomes concern the occurrence of a surgical site infection diagnosed by the surgeon in charge of the patient, one month and three months after surgery; it may concern the pre operative period, the procedure itself, or the early post operative period, characterized by a high density of cares, or even the late rehabilitation, after discharge of the surgical unit. Secondary outcome evaluate the profile of agents identified regarding the susceptibility of the prophylaxis recommended to prevent wound infection; it may suggest that an adequate antibiotic prophylaxis is often insufficient to take into account the responsible agents, and that decolonisation is not always that helpful, in view of emerging cases of failure due to developing resistance. Considering the low incidence of that type of complication, the investigators estimated that a period of two years might be necessary to include a sufficient number of patient, at least one thousand, in order to find a dozen of factors that might be significantly associated with an increased risk of surgical site infection. The evaluation is permitted by the collaboration between the anesthesiologists, surgeons, intensivists, hygienists, all along the presence of the patient in the department, until discharge out of the hospital and after readmission eventually for infectious complication.

Respiratory complications represent the second most frequent type of postoperative complications with an incidence estimated to range from 2.0% to 7.9% It has been shown that intra-operative protective ventilation is associated with a reduced risk of respiratory complications. The effects of intra-operative inspiratory oxygen fraction (FiO2) remain to be investigated. In this study, the investigators aim to investigate the association between intra-operative FiO2 and respiratory complication as well as surgical site infection and ICU admission in patients undergoing non-cardiothoracic surgery. The investigators primary hypothesis is that high intra-operative FiO2 increases the risk of postoperative respiratory complications independent of predefined risk factors.

A surgical site infection (SSI) is an infection that occurs after surgery in the part of the body

This is a nationwide multicenter,retrospective,observational real-world study. To assess the risk of perioperative complications in patients with tumor who received bevacizumab prior to unexpected operation. To assess the correlation of the interval time between the last dose of bevacizumab and operation and occurrence of perioperative complications. To explore the risk factors of perioperative comlications in patients with tumor received bevacizumab prior to unexpected operation.

To assess whether the practice of using separate sterile gloves and instruments to close wounds at the end of surgery compared to current routine hospital practice can reduce surgical site infection

This is a implementation research study of a surgical wound tele-monitoring online tool developed at the University of Edinburgh and demonstrated in the "Tracking wound infection with smartphone technology" (TWIST) randomised control trial (NCT02704897) conducted in NHS Lothian. The study design is based on the Medical Research Council (MRC) "Guidance for developing and evaluating complex interventions".

The negative effect of internal mammary harvesting on sternal perfusion is well known, especially in diabetic subjects. Microdialysis previously showed increased lactate tissue concentration after mammary artery preparation. Although high antibiotic concentration is of utmost importance in this region, no study previously measured the effect of internal mammary artery harvesting on target tissue antibiotic concentration. Study hypothesis: Internal mammary artery harvesting imposes an additional risk for deep sternal wound infection by impairing antibiotic tissue penetration. This effect is mediated by altered perfusion patterns and may be seen in cephalosporin and/or Teicoplanin treatment. Study objective: To evaluate the impact of left internal mammary artery preparation on target tissue antibiotic concentration of Cefazolin and Teicoplanin during cardiac surgery Design: This study is designed as an observational pharmacokinetic trial. Patients are their own controls by measuring antibiotic concentration in different subcutaneous tissues. Study population: Patients referred for coronary artery bypass grafting to the Department of Cardiothoracic Surgery with planned unilateral left internal mammary artery preparation and a high risk profile for deep sternal wound infections will be asked to participate in this trial.

Rationale: Surgical site infection (SSI) is one of the most frequently reported postoperative complication, occurring in up to one-third of patients. Its development causes a substantial increase in the clinical and economic burden of pancreatic surgery. Nowadays, the primary goal of a surgical department is the reduction of the SSI rate, based on a cautious approach to the prescription of the antibiotic prophylaxis (AP) to avoid the spread of multi-drug resistant (MDR) bacteria. An antimicrobial stewardship program and a patient-tailored antibiotic prophylaxis could be an optimal strategy to reduce the impact of infectious complications after pancreatic surgery. However, few data are available regarding this topic. Objective: To evaluate the useful of an antimicrobial stewardship program and a patient-tailored antibiotic prophylaxis in the reduction of the occurrence of SSI and the inappropriate use of key antibiotics in patients undergoing pancreatic surgery. Study design: A time series study will be conducted. The antimicrobial stewardship program is shared between three national high-volume centers of pancreatic surgery. Statistical significance and effect size were calculated by segmented regression analysis of interrupted time series of drug use, SSI rate, and costs for 3 years before and after the introduction of the program. Study population: Patients with an indication for elective pancreatic surgery. Main study parameters/endpoints: Primary outcome is the reduction of SSI rate. Secondary outcomes are the reduction of the use of the key antibiotics (such as piperacillin/tazobactam and carbapenems), the microbial whole-genome sequencing (WGS) of the carbapenemase-producing Enterobacteriaceae, and the reduction of the treatment costs

Background: Cancer-related fatigue (CRF), one of the indicators of QoL, is one of the most common side effects of cancer and its treatment. However, the pathophysiological mechanisms involved in CRF among cancer patients are not completely understood. Therefore, more in-depth researches on CRF of surgical patients suffering from gastric cancer are needed in Taiwan. Purpose: The purpose of this study is to examine the incidence rate and correlated factors (QoL and immune biomarkers) of CRF among gastric cancer patients undergoing major abdominal surgery. Method: A longitudinal study was conducted to recruit gastric cancer patients who scheduled to operate at surgical clinics from a northern medical center in Taiwan. The data will be collected with a structured questionnaire and Immune markers assessments via purposive sampling of 120 subjects. Before operation, on day 1 after operation, and on day 7 after operation, the biomarkers will be measured. The BFI-T questionnaire will be filled out before surgery and on day 1, 2, 7, 28 after surgery; The EORTC QLQ-C30 and EORTC QLQ-STO22 questionnaire will be filled out before surgery and on day 7, 28 after surgery; Type D scale-14(Taiwanese version) questionnaire will be filled out before surgery and on day 28 after surgery. Data will be analyzed by using descriptive statistics, paired t-test, Chi square test, Pearson's correlation, and the generalized estimating equation (GEE) was used to identify significant factors with QoL after operation. Anticipated achievement: The anticipated achievement of this study is to provide healthcare providers with more knowledge about CRF, and help them to enhance the quality of life on gastric cancer patients in the future.
