View clinical trials related to Intra-Abdominal Hypertension.
Filter by:Acute pancreatitis(A) often complicated with Intra-abdominal Hypertension. After the onset of acute pancreatitis, capillary leakage causing ascites,upper gastrointestinal tract obstruction and paralytic ileus leading to an elevated IAP, severe IAH leads to ACS with high mortality. Neostigmine is an anti-cholinesterase drugs, can enhance intestinal peristalsis, promote flatus defecation. The aim of this study was to determine the effect of neostigmine on reducing abdominal pressure and clinical prognosis in patients with AP by promoting intestinal peristalsis and defecation.
The aim of the proposed study is to determine the incidence and prevalence of intra-abdominal hypertension and abdominal compartment syndrome in consecutive intensive care admissions using broad inclusion criteria.
The purpose of this study is to evaluate the changes of intraocular pressure due to the increase of intra abdominal pressure.
The goal of this study is to describe the influence of the chest wall on the respiratory system mechanics in morbidly obese patients and in patients with high intra-abdominal pressure. The effects of increasing and decreasing positive end-expiratory pressure (PEEP) on chest wall and total respiratory system mechanics, lung volumes and gas exchange will be evaluated, both during controlled and assisted mechanical ventilation. Patients will be studied, first, during the acute phase of respiratory failure, when requiring intubation and controlled mechanical ventilation. Then, patients will be evaluated again during weaning from the ventilator to assess the influence of PEEP in assisted ventilation prior to extubation.
- Intra-abdominal pressure(IAP) is defined as a steady state pressure of the abdominal cavity - many studies have proved IAP as a prognostic factor that elevated IAP influences hemodynamics and multiple organs dysfunction - In previous studies, most of them was based on the septic patients of medical diseases. And it is rare about sepsis of surgical diseases such as traumatized or postoperative patients - We hypothesized that intra-abdominal hypertension may affect clinical course such as length of stay of intensive care unit, weaning of mechanical ventilation, proceeding of enteral feeding and mortality - Our study was aimed to investigate prevalence of IAH and risk factors and to analyze clinical course and prognosis influenced by IAH in surgical patients with severe sepsis
This study assess the relation between intra abdominal pressure and collapsibility index of inferior vena cava in emergency bedside ultrasonography before and after fluid therapy.
As an important management of severe acute pancreatitis (SAP), enteral nutrition (EN), especially early enteral nutrition (EEN) increases the blood flow of gut mucosa and stimulates the intestinal motility. Moreover, EEN maintains the gut integrity, prevents bacterial and endotoxin translocation and thereby theoretically reduces the incidence of infections. Therefore, EEN has the ability to reduce the infectious complications, length of hospital stay and mortality of patients with SAP. However, the role of EEN is considered to be influenced by intra-abdominal hypertension (IAH) in patients with SAP. The previous studies showed that gut was the most sensitive splanchnic organ to the increase of intra-abdominal pressure (IAP). When IAH occurs, it reduces the blood flow of gut, and then results in the development of intestinal ischemia and edema. The hypoxia and hypoperfusion of intestine leads to the increase of permeability of the intestinal mucosal barrier, and then leads to bacterial translocation. Therefore, IAH could result in the gastrointestinal dysfunction. Nevertheless, the different impacts of specific IAP values on the tolerance of EEN have not been reported. Furthermore, the effects of early enteral feeding on the IAP in SAP also remain unknown. Due to the severe inflammatory response of SAP, could EEN increase the burden of bowel, cause expansion of intestinal cavity, thus increase IAP? However, there were rare literatures up to date reporting the association between EEN and IAH in patients with SAP. Therefore, the present study aimed to investigate the influence of specific IAP on the tolerance of early enteral feeding, as well as the effects of EEN on IAP in SAP patients. Moreover, the impacts of EEN on the disease severity and clinical outcome of SAP were also researched.
This pilot study will evaluate the effectiveness in actively removing the peritoneal fluid through the use of a commercial suction device compared to passive drainage of the same peritoneal fluid drained through standard surgical drains under bulb suction only, in critically ill patients who require an "open abdomen". Both techniques being used, the commercial KCI AbThera™ device and home made "Stampede" VAC system, are currently approved for use in Canada and used in our facility. The use or non-use of the open abdomen and its relationship to intra-abdominal hypertension (IAH) and the abdominal compartment syndrome (ACS), the level of IAH must be treated and if so how should be treated - remain controversial. The ultimate treatment for IAH/ACS is to leave the abdominal fascia open after laparotomy, utilizing some form of temporary abdominal closure (TAC) techniques, resulting in an "open abdomen"(OA). The decision to accept an OA can only be made in the operating room and is typically made quite arbitrarily (there is no current standard or protocol),and the TAC used is based on the surgeon's best judgment. The study intends to randomize patients after it has been decided that a TAC is required, which will be applied in the operating room while the patient is fully anesthetized. The only intervention required is to obtain small aliquots (a teaspoonful-15ml) of blood for the evaluation of inflammatory mediators levels, as well as the same volume of intra-peritoneal fluid-that is typically discarded in patients with OA.
Background: Fluid resuscitation is a cornerstone of the initial management of the critically injured trauma patient yet there are numerous controversies surrounding this very common practice. As a result, these controversies have been the subject of numerous clinical trials, evidence-based guidelines and systematic reviews. With the publication of the landmark SAFE Study the equipoise between the 2 treatments (which were representative solutions for colloid and crystalloids respectively), 4% albumin and saline, was established. This has however been brought into further doubt by the paucity of data on the use of hydroxyethylstarches (HES), which are less costly and have less side effects than albumin, in trauma. More recent findings by Gruen and colleagues have shown that as much as 5% of all trauma deaths are the result of fluid overload based on the North American fluid management model for trauma (pure crystalloid fluid management). A meta-analysis done by Kern and Shoemaker found that supranormal fluid resuscitation with crystalloids is beneficial when given before the onset of organ failure in critically ill surgical patients. Balogh and colleagues found out that when supranormal fuid resuscitation with crystalloids was applied to victims of severe trauma, this resulted in a statistically significant increase in the incidence of mortality, multiple organ failure, intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS). More recently, Kirkpatrick and colleagues reviewed and defined a 'secondary' ACS as a direct result of fluid resuscitation. They concluded that "excess resuscitation with crystalloid fluids might be harming patients and contributing to an increased occurrence of ACS." This study will serve as a pilot to test the hypothesis that there will be significant differences in clinical outcomes for patients with severe trauma treated with colloid (HES) plus crystalloid and crystalloid only fluid management regimens, most notably the incidence of IAH and ACS. It is hoped that the hybrid colloid (HES) plus crystalloid fluid management regimen will provide a means to avoid the untoward fluid overload and/or other complications of pure crystalloid fluid management and the costs/complications of albumin administration.
The observational study is designed to determine the feasibility of performing Intra-Abdominal Pressure (IAP) via bladder pressure measurements and of tracking IAP in neonates who require bladder catheterization. Correlation of IAP measurements with clinical status of the neonatal abdomen will help determine threshold values for Intra-Abdominal Hypertension (IAH) in the neonate.
