At the end of most abdominal operations, the fascial layer is closed by stitching edges of the wound together. However, because of logistic and/or technical reasons or the patient's critical condition, the surgeon is forced to leave the abdomen open. The current approach for temporary coverage of abdomen is vacuum assisted techniques (VAT). This technique requires the use of vacuum-assisted drainage to remove blood or watery fluid from a wound or operative site. Although this is the most successful and commonly used procedure, there are some limitations to this method. For example, VAT have little effect on preventing lateral movement of the wound edges. Therefore, VAT it is not the ideal procedure in aiding surgeons to closed the abdomen. The purpose of this study is to compare usual care (vacuum or non-vacuum methods for temporary coverage of the OA) versus usual care plus a novel new abdominal binder device called ABRO™ that may aid in the closure of patients who undergo open abdomen closure procedures.
Early detection and timely therapeutic intervention can improve the prognosis of patients with sepsis. However, early diagnosis of sepsis can be difficult; because determining which patients presenting with signs of infection during an initial evaluation, do currently have, or will later develop a more serious illness is not easy. Physiological deterioration often precedes clinical deterioration as patients develop critical illness. In this study, the investigators aim to evaluate vital signs in a global cohort of patients with acute secondary peritonitis, determining which parameters are statistically significant to predict in-hospital mortality and ICU admission.
This is a prospective randomized clinical study. The study will comprise the randomized decision to either A) primarily close the fascia after laparotomy for intra-abdominal infection (CLOSED); or B) leave the fascia open after laparotomy and apply a temporary abdominal closure (TAC) device (OPEN) with a vacuum drain. Although debatable, both procedures (CLOSED or OPEN abdomen) are acceptable based on current suggested standard of care. Thus, high quality data to direct clinical decision making in this highly lethal condition is urgently required.
This study aims to evaluate the efficacy of ultrasound derived variables in prediction of success of weaning from mechanical ventilation in critically ill patients with abdominal sepsis
This study is being done to compare two different Temporary Abdominal Closure methods that could be used in cases like yours. The methods being compared are the Barker's vacuum packing technique (BVPT) and the Open Abdomen Negative Pressure Therapy System (ABThera).
Septic shock of intra-abdominal origin is likely due to Gram-negative bacteria or mixed pathogens and associated with high levels of endotoxin. The injury to the endothelium results in an increase of endothelial permeability, interstitial edema and release of nitric oxide (NO) that is a very potent vasodilatator.  Polymyxins obtained from the Gram-positive bacterium Bacillus polymyxa are antibiotics known for their ability to bind LPS in the outer membrane of the Gram-negative bacterial cell wall as well as free endotoxins with high affinity. Polymyxin-B has been shown to block the activation of cells by a wide variety of LPS. Studies converged to show an improvement in the treatment of septic shock by removing circulating endotoxin.Starting Polymyxin-B hemoperfusion during the operative time is to block the initiation of various deleterious biological cascades induced by endotoxemia such as systemic inflammation, disseminated coagulation disorders, and shock, leading to organ dysfunction and death.
PSP (Pancreatic Stone Protein) is a compound naturally produced mainly in the pancreas and the gut. There is evidence from experimental and clinical trials that the levels of PSP in the blood rise in the presence of inflammation or infection. What is not yet well known about PSP is whether it is superior to other established blood tests (e.g. WBC or CRP) in predicting appendicitis in patients that present at the emergency room with abdominal pain and a clinical suspicion of appendicitis.
Protocol Synopsis Protocol title: Assessment of peritoneal immune response in patients with severe intra-abdominal sepsis managed by laparostomy and VAC Purpose: Assessment of peritoneal immune response in patients with severe intra-abdominal sepsis Design: Prospective, single-center study Patient Population: Male or female adults (>18 years) with severe intra-abdominal sepsis No. of Subjects: 60 patients divided into two groups, 30 patients with severe intra-operative sepsis and 30 patients without sepsis scheduled to undergo major abdominal operations (middle line incision>15cm). The study is estimated up to 2 year to enroll Duration of Follow-up: Follow-up will be performed daily while hospitalized, until patient discharged or deceased. Endpoints: 1. To measure the peritoneal cytokines levels in patients with severe intra-abdominal sepsis. 2. To correlate the cytokines levels in the abdominal cavity and the serum plasma. 3. To correlate cytokines response in serum plasma and peritoneal fluid with mortality and morbidity. 4. To compare cytokines results in serum plasma and peritoneal fluid between patients with severe intra-abdominal sepsis and patients undergoing major laparotomy without sepsis. 5. To assess the microbial load in the abdominal cavity in patients with severe sepsis. 6. To assess the biofilm formation in VAC polyurethane sponge.
