Post-surgical (bacterial) infections are the most frequent post-surgical complications, including deep or superficial wound infections, urinary tract infections, pneumonia, and even sepsis. Approximately 6.5-25% of all surgical patients will develop any type of bacterial infection. To personalize surgical infection management, (Artificial Intelligence) models are in the making to predict which patients are at high or low risk of developing a post-surgical infection. In order to benchmark these prediction models to the predictive capabilities of surgeons, the investigators aim to investigate the performance of surgeons in predicting the risk of a patient developing (any type) of post-surgical infection within 30 days.

Cerebral desaturations occur frequently in patients undergoing non-cardiac surgery. The definition of what constitutes a cerebral desaturation, the incidence of the phenomenon, the association between desaturations and perioperative outcome, and the mechanistic explanations of cerebral desaturations remain unexamined. This study seeks to identify the true incidence and magnitude of cerebral desaturations in high-risk non-cardiac surgical patients and the association between desaturations and perioperative outcome. The investigators will attempt to determine the following (1) The proper definition, incidence and severity of decreased cerebral saturation (rSO2) in high-risk non-cardiac surgical patients (2) the mechanisms surrounding decreases in rSO2 by correlating it with alterations in physiologic parameters (such as blood pressure, cardiac output, hemoglobin concentration, and carbon dioxide levels) and (3) to correlate the incidence and severity of decreased rSO2 with relevant perioperative. The investigators will also analyze a panel of inflammatory biomarkers to determine if these biomarkers have the ability to predict postoperative complications. The investigators will study 200 high-risk patients undergoing high-risk non-cardiac surgery. The investigators will determine the incidence and severity of decreases in rSO2, the associated factors with the occurrence of decreased rSO2, and the relationship between decreases in rSO2 and adverse perioperative outcome with a composite of well defined perioperative complications such as death, myocardial infarction, cerebrovascular accident, acute kidney injury, delirium, postoperative infections, and the need for mechanical ventilation.
NCT06547281
Utilizing machine learning techniques, investigators developed the geriatric infection assessment model, leveraging domestic databases to predict multiple postoperative infections in elderly patients. The model addresses the current gap in predictive tools tailored for elderly surgical patients in China, offering insights into both overall and specific infection risks.
NCT06044428
The goal of this observational study is to review whether postoperative infections can be detected earlier by a continuous measurement of body temperature of patients compared to single daily measurements. Within 25 weeks 100 patients, which underwent visceral surgery less than 48h ago, will be included. A patch (Steadytemp ®) will be attached to participants, continuously measuring the body temperature. In addition infection parameters and medication of the participants will be documented.
NCT05052619
Intra-abdominal infection is one of the most serious complications after pancreatic resection. The preventive use of antibiotics intraoperatively could reduce the incidence rate of postoperative intra-abdominal infection. According to the previous retrospective study, changes of serum lactate level on postoperative day1 could predict the incidence rate of postoperative intra-abdominal infection. This prospective RCT is to further validate and promote the findings and conclusion.
NCT03231228
This is a Phase 4, open-label, single-dose, parallel-group, multicenter, safety study of cefazolin (1 g or 2 g) in pediatric subjects between 10 and 17 years of age (inclusive) scheduled for surgery.
NCT03990974
This trial is a multi-center, double-blinded, randomized (1:1) clinical trial. The aim is to compare the postoperative infection rate between the 3 days postoperative AMP group and the placebo group in HCC patients undergoing hepatectomy.

Post-operative antibiotics for infection prophylaxis are routinely given to most surgical patients, and for orthopaedic surgery patients, the standard of care is treatment for 24 hours following any elective procedure (1). The most concerning risk for insufficient antibiotic coverage in the post-operative period is the development of a complicated infection requiring irrigation and debridement or revision surgery. Moreover, recovery from surgery is usually delayed in patients that have postoperative wound infections leading to increased resource utilization and increased economic cost for the health care system. It is clear that prophylactic antibiotic therapy is necessary in the immediate post-operative period, but the length required continues to be debated. Orthopaedic patients undergoing elective spine surgeries often require the placement of a hemovac drain which applies gentle suction to remove excess fluid/blood and to promote healing. Wound drains, however, may also increase the risk of post-operative infection because they expose the "clean" interior aspect of the wound to the "dirty" exterior area around the wound. Given this additional focus of infection, it is unknown whether prolonged antibiotic therapy post-operatively is needed to decrease the rate of infection in this population (2,3). There is sparse literature evaluating the effectiveness of prolonged antibiotic therapy in decreasing complicated post-operative infection requiring irrigation and debridement in this population (1,4). To our knowledge, there are no recent studies comparing prophylactic antibiotics for 24 hours only post-operatively versus 24 hours after removal of the drain. In fact, a recent evidence-based review of the literature by the North American Spine Society highlighted the need for research in this area (5). The proposed study will compare two patient populations who will receive various lengths of post-operative antibiotics. One will receive only 24 hours worth, and the other will receive antibiotics for 72 hours after surgery and the rate of complicated infection compared between the two. The absence of a demonstrable difference suggests that antibiotic prophylaxis for only 24 hours immediately post-operatively is sufficient for all elective spine patients undergoing posterior spine procedures requiring the placement of a hemovac drain.
