|Intra-Abdominal Hypertension||Drug: furosemide||Not Applicable|
Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) have been shown to cause organ dysfunction and mortality in different populations of critically ill patients. According to consensus definitions published by the World Society for the Abdominal Compartment Syndrome (WSACS), secondary IAH is due to a disease process outside the abdominal cavity. It is mainly caused by massive fluid resuscitation leading to bowel and abdominal wall edema or increased intra-abdominal volume and decreased abdominal wall compliance. Large observational studies have shown that positive fluid balance is an independent risk factor for mortality. The development of secondary IAH may be one of the mechanisms involved in this phenomenon. This has lead to the hypothesis that prognosis may be improved by managing fluid overload and aiming for a negative fluid balance as soon as possible after the resuscitation phase of the disease.
Several authors have shown in case reports and small series that renal replacement therapy with ultrafiltration can be used successfully to remove excess fluid and lower intra-abdominal pressure (IAP), but renal replacement therapy is invasive and clinicians may be reluctant in considering this therapy in patients with preserved diuresis and kidney function. In an effort to achieve the same goal using a less invasive technique, the new medical management algorithm for IAH published by the WSACS recommends the use of judicious diuresis in order to achieve a negative fluid balance and a decrease in IAP.
However, the kidney is especially sensitive to the deleterious effects of IAH and may be unresponsive to diuretics in the presence of IAH. Also, ongoing inflammation and capillary leak may lead to relative hypovolemia and impaired response to diuretics.
We plan a multicenter study to evaluate the influence of furosemide on fluid balance and IAP in critically ill patients with secondary intra-abdominal hypertension and to document the effect on the function of other organ systems. The aim of this study is to evaluate the feasibility and the safety of the furosemide administration protocol and to provide preliminary data to allow for an adequate power calculation.

|Intervention Model:||Parallel Assignment|
|Official Title:||The Influence of Furosemide on Fluid Balance and Intra-abdominal Pressure in Mechanically Ventilated Critically Ill Patients With Secondary Intra-abdominal Hypertension|
|Study Start Date :||February 2010|
|Estimated Primary Completion Date :||December 2011|
|Estimated Study Completion Date :||March 2012|
No Intervention: Control group
Patients will be receiving standard of care ICU treatment of their underlying disease according to internationally accepted guidelines and recommendations.
Experimental: Furosemide group
patients will be receiving standard of care ICU treatment of their underlying condition according to international guidelines and recommendations. In addition, furosemide will be administered in continuous infusion as per protocol in order to achieve a preset target diuresis that is adjusted according to haemodynamic tolerance.
Loading dose: 0,5mg/kg Start continuous infusion at a dose of 0,1mg/kg/h and titrate according to diuretic response.
Target value for diuresis = (amount of fluids administered at inclusion/kg/h) + 0.5mL/kg/h If safety check is satisfactory: increase target diuresis with 1mL/kg/h per 4h to a maximum of (amount of fluids administered at inclusion/kg/h) + 2.5mL/kg/h Maximal dose of furosemide: 0.3mg/kg/h Safety check every 4h. Furosemide is administered for 24h. If safety checks are satisfactory, additional periods of 24 can be added up to a maximum of 72h.
