Filter by:Intraoperative hemodynamic management is vital in the success of lung transplantation. Significant intraoperative hemodynamic compromise and hypoxic episodes may contribute to an increase in severe postoperative complications related to hypoperfusion, including cerebrovascular accidents, acute kidney injury, and mesenteric ischemia. In certain lung transplant recipients, intraoperative cardiopulmonary support is mandatory because certain factors would make "off-pump" transplants unsafe. These include severe pulmonary hypertension or severe ventricular dysfunction. In such patients, routine intraoperative support should be employed. However, it is possible to conduct the lung transplant without cardiopulmonary support in the remainder of patients who do not have severe pulmonary hypertension or right heart dysfunction. In such patients, the lung transplant may be started without cardiopulmonary support. However, cardiopulmonary support may be initiated "on-demand" if there is development or impending hemodynamic embarrassment or hypoxia. Conversely, the opposite approach would be to routinely conduct all lung transplant operations using cardiopulmonary support, which may also lead to specific ECMO-related complications. The investigators question whether on demand intraoperative ECMO in patients with significant risk factors will produce severe postoperative complications in a rate similar to routine ECMO.
The primary aim of this study is to investigate and test whether the use of combined indocyanine green (ICG) lymphography and ultra high frequency ultrasonography can correctly identify lymphatic vessels and venoles in close proximity to each other, for identification prior to lymphovenous anastomosis (LVA) surgery.
Rates of major complications and mortality in the first weeks after surgery remain very high: postoperative mortality is still around 2% in central Europe and the United States. Postoperative deaths are a consequence of postoperative complications. Postoperative complications that are most strongly associated with postoperative death include acute kidney injury and acute myocardial injury. To avoid postoperative complications it is thus crucial to identify and address modifiable risk factors for complications. One of these modifiable risk factors may be intraoperative hypotension. Intraoperative hypotension is associated with major postoperative complications including acute kidney injury, acute myocardial injury, and death. It remains unknown which blood pressure value should be targeted in the individual patient during surgery to avoid physiologically important intraoperative hypotension. In current clinical practice, an absolute mean arterial pressure threshold of 65mmHg is used as a lower "one-size-fits-all" intervention threshold. This "population harm threshold" is based on the results of retrospective studies. However, using this population harm threshold for all patients ignores the obvious fact that blood pressure varies considerably among individuals. In contrast to current "one-size-fits-all" perioperative blood pressure management, the investigators propose the concept of personalized perioperative blood pressure management. Specifically, the investigators propose to test the hypothesis that personalized perioperative blood pressure management reduces the incidence of a composite outcome of acute kidney injury, acute myocardial injury, non-fatal cardiac arrest, and death within 7 days after surgery compared to routine blood pressure management in high-risk patients having major abdominal surgery. The investigators will perform preoperative automated blood pressure monitoring for one night to define individual intraoperative blood pressure targets. Automated blood pressure monitoring is the clinical reference method to assess blood pressure profiles. The mission of the trial is to reduce postoperative morbidity and mortality after major surgery. The vision is to achieve this improvement in patient outcome by using the innovative concept of personalized perioperative blood pressure management. This trial is expected to change and improve current clinical practice and will have a direct impact on perioperative blood pressure management guidelines.
Lengthy hospitalization and immobility can lead to muscle loss resulting in reduced recovery rates and prolonged hospital stay or readmission. Older adults discharged from hospitals are at an increased risk for functional decline, falls and disability. Daily exercise and physical activities have proven to enhance the recovery and discharge process for older patients from the hospital and ultimately save vast amounts of dollars each year. The aim of this study is to initiate early mobilization and decrease the rate of functional decline in post-surgical older adults' patients in the acute care hospital setting in Alberta, Canada. The investigators are implementing a BE-FIT (BEdside reconditioning for Functional ImprovemenTs) a quality improvement, evidence-based exercise program that focuses on early mobilization and recovery by minimizing bed rest, promoting functional tasks, and encouraging self-management. Patients enrolled in the program will receive a bedside exercise plan to be completed independently throughout their stay in the hospital. Control patients will receive usual care without the added exercise plan. Patient mobility during their hospital stay will be assessed pre and post BE-FIT initiation according to a predetermined mobility scoring system. Secondary outcomes will include: time-to-mobility, length of stay, complication incidence and hospitalization costs.
This study compared differences in weight loss, comorbidity resolution and complications and reoperations between a recently established sleeve gastrectomy (SG) and prior laparoscopic Rox-en-Y gastric bypass (RYGB).
Despite modern approaches to the diagnosis and treatment of acute bowel obstruction (ABO), postoperative mortality ranges from 5 to 32%, and complications occur up 23% of cases. One of the formidable infectious and inflammatory complications of ABO is sepsis. The main component of the development of sepsis in ABO is bacterial translocation (BT). BT is the migration of intestinal bacteria or their products through the intestinal mucosa into the mesenteric lymph nodes and further into normally sterile tissues and organs. Today there are several methods for detecting BT: 1. direct method - the detection of 16s rRNA (ribosomal ribonucleic acid) in mesenteric lymph nodes (MLN); 2. indirect method - the detection of serum lipopolysaccharide-binding protein (LBP) and presepsin (Soluble CD14 subtype or sCD14-ST). The aim of this study is to determine the diagnostic and prognostic significance of bacterial translocation as a predictor of the complications development in patients with malignant and benign acute bowel obstruction by assessing the relationship of biomarkers in the systemic circulation (LBP, sCD14-ST) with the detection of microorganism genes (16s rRNA) in mesenteric lymph nodes.
The incidence of myocardial injury after non-cardiac surgery (MINS) is approximately 12-15% and is associated with an increased risk of 30-day mortality, 1-year mortality, and 2-year major vascular events. Using both traditional longitudinal analysis techniques and novel methods in machine learning, investigators will explore whether intraoperative and postoperative vital signs can enhance MINS surveillance by providing temporal prediction of MINS events.
There are 2 types of surgical procedures to remove the appendix : open appendectomy or laparoscopic appendectomy. About 60000 appendectomies are performed every year in France. Early diagnosis of acute appendicitis is essential to prevent the risk of disease progression, leading to complicated appendicitis and an increased risk for mortality. Data regarding appendicitis management in the literature are numerous. However, the impact of COVID-19 pandemic on the management of those patients has led to a decrease in the number of visits for acute appendicitis (ER), but a higher proportion of complicated appendicitis, probably due to the patient's delayed decision to go to emergency department at the onset of clinical symptoms. Complicated appendicitis may also lead to an overuse of antibiotics, a longer hospital stay, and a higher global cost for the health system. This aim of this study was to evaluate whether this hypothesis was valid for the regional NANCY-METZ area (CHR Metz and CHRU Nancy). The main research hypothesis was that the pandemic caused by SARS-COVID 19 was significantly linked to an increased incidence of perioperative complications in patients who underwent an appendectomy for acute appendicitis in this region (North-east part of France).
Purpose: The purpose of this study is to create prediction models for when major complications occur after elective colectomy surgery. Justification: After surgery, patients can have multiple complications. Accurate risk prediction after surgery is important for determining an appropriate level of monitoring and facilitating patient recovery at home. Objectives: Investigators aim to develop and internally validate prediction models to predict time-to-complication for each individual major medical complications (pneumonia, myocardial infarction (MI) (i.e. heart attacks), cerebral vascular event (CVA) (i.e. stroke), venous thromboembolism (VTE) (i.e. clots), acute renal failure (ARF) (i.e. kidney failure), and sepsis (i.e. severe infections)) or adverse outcomes (mortality, readmission) within 30-days after elective colectomy. Data analysis: Investigators will be analyzing a data set provided by the National Surgical Quality Improvement Program (NSQIP). Descriptive statistics will be performed. Cox proportional hazard and machine learning models will be created for each complication and outcome outlined in "Objectives". The performances of the models will be assessed and compared to each other.
An observational, analytical, multicentre prospective cohort study will be conducted throughout Colombia. A sample size of 1353 patients is needed to achieve significance in our primary objective; however, convenience sampling is considered, as we aim to include all the institutions and patients possible. The data collection will be carried out prospectively for one week, and all patients will have a follow-up of a maximum of 30 days in-hospital. The primary outcome will be to determine the in-hospital mortality. We aim to contribute with accurate information on in-hospital postoperative mortality in Colombia. Thus, by following precisely the instructions created by The Lancet Commission on Global Surgery. The data obtained will help formulate public policies in the surgical field adjusted to the Colombian population, improving the quality of the surgical divisions in the different Colombian institutions, positively affecting the attention and development of the Colombian healthcare system.
