The optimal fluid regimen, haemodynamic (or other) targets and fluid choice (colloid or crystalloid) for patients undergoing major surgery are based on rationales that are not supported by strong evidence. Practices vary substantially, guidelines are vague, small trials and meta-analyses are contradictory. The strongest and most consistent evidence, and biological plausibility because of tissue edema, supports a restrictive fluid strategy. But other evidence supports goal-directed therapy, requiring additional IV fluid. There is no good evidence that use and choice of colloids improves outcome. RELIEF will study the effects of fluid restriction, and the possible effect-modification of goal-directed therapy and colloids. The first will be randomly assigned; the latter will be measured covariates dictated by local practices and beliefs. Study Hypotheses A restrictive fluid regimen for adults undergoing major abdominal surgery leads to reduced complications and improved disability-free survival when compared with a liberal fluid regimen. Secondary hypothesis: The effects of fluid restriction are similar whether or not goal-directed therapy is used (assessed as a statistical test of interaction). A restrictive fluid regimen will reduce a composite of 30-day septic complications and mortality.
The purpose of this study is to assess the roll of pre-operative chest physiotherapy, in addition to the usual care given after major abdominal surgery, in the prevention of post-operative respiratory complications.
This is a research study testing SABER-Bupivacaine (an experimental pain-relieving medication). SABER-Bupivacaine is designed to continuously deliver bupivacaine, a common local anesthetic, for a few days in order to treat local post-surgical pain. The purpose of this study is to investigate safety (side effects) associated with the use of SABER-Bupivacaine and how well it works in reducing pain and opioid-related side effects following various kinds of abdominal surgeries.
Hypothesis: Plastic wound retractors reduce passage of bacteria from the abdomen to the surgical incision site in abdominal surgery Currently, plastic wound retractors are used in abdominal surgery to facilitate access to the abdominal cavity. This study aims to establish whether they also prevent bacteria crossing from the abdominal cavity to the surgical incision site. Patients undergoing abdominal surgery in which a plastic wound retractor (Alexis®)is used are eligible for inclusion in the study. Swabs are taken from the inside and the outside of the plastic wound retractor prior to removing the retractor from the abdomen. The bacterial flora from swabs taken inside and outside the plastic wound protector are then compared to see if there is any difference between inside and outside the retractor. Bacteria are classified as 'enteric'(i.e. from the gastrointestinal tract) or 'skin' bacteria, depending on their usual location. The study aims to establish whether a plastic wound retractor (Alexis®) reduces translocation of enteric bacteria to the surgical incision site.
The purpose of this study is to measure the acute renal dysfunction on the first, second, seventh and twentieth days.
Tissue hypoxia is one of the most important factors leading to the development of multiorgan failure. Patients presenting for emergent major abdominal surgery might suffer from organ hypoperfusion. Thus, early detection of the imbalance between oxygen supply and demand may improve the outcome. The investigators believe that hypoperfusion of the abdominal organs will cause a decrease of the saturation in the hepatic vein and in the IVC.
The study is planned to check the analgesic and anti-inflammatory properties of Atorvastatin in patients who will be undergoing abdominal surgery under spinal anesthesia. The investigators intend to monitor the analgesic requirements, the rate of wound healing and the inflammatory markers in this trial.
Summary Question: Does backward walking offer additional therapeutic value in patients after aortic aneurysm surgery? Participants: The study of backward walking as an addictive physiotherapy procedure was conducted in the group of 65 patients who underwent abdominal aorta surgery. The patients were randomly divided into three subgroups and three various models of physiotherapy were applied. Control group has only routine physiotherapy since therapeutic group I and II have also walking exercises forward in group I and backward in group II respectively.
This randomised placebo controlled double-blinded bicentre study (phase III) was designed to evaluate the preemptive and postoperative analgetic impact of etoricoxibe in open abdominal and thoracic surgery. Etoricoxib selectively inhibits isoform 2 of cyclo-oxigenase enzyme (COX-2). Therefore 120 patients (ASA-risk 1-2) with upcoming abdominal or thoracic surgery should be included into this study. Patients are randomly allocated to either the preemptive or the postoperative Etoricoxibe group. These two groups are divided each into two arms. Preemptive group patients get Etoricoxibe either twice (before and after surgery) or just a single preoperative dose. Postoperative group patients get placebo before surgery and either a drug application or a placebo again after surgery (so called 2x2 factorial study design). Cumulative use of morphine as assessed within first 48 hours after surgery is the primary trial outcome indicating the analgesic potency of Etoricoxibe. In addition, changes in patients level of sensibilisation will be measured with help of quantitative sensory testing (a standardised procedure) before and after surgery (secondary outcome). In addition pharmacogenetic testing will provide information about genetic aberrations (so called polymorphisms) of the patients enzymes that should be compared to the individual reaction regarding Etoricoxibe. The results will give hint about the analgesic impact of etoricoxibe in acute postoperative pain. There will be findings for preemptive analgesia and nerval processes. All this could lead to an improvement of postoperative pain relief while administrating preemptively a COX-2 selective inhibitor before surgery.
