The Influence of Furosemide on Fluid Balance and Intra-abdominal Pressure in Critically Ill Patients

February 19, 2010 updated by: Ziekenhuis Netwerk Antwerpen (ZNA)

The Influence of Furosemide on Fluid Balance and Intra-abdominal Pressure in Mechanically Ventilated Critically Ill Patients With Secondary Intra-abdominal Hypertension

Intra-abdominal hypertension (IAH) is a frequent cause of organ dysfunction in critically ill patients. Secondary IAH is mainly caused by excessive fluid resuscitation.The World Society for the Abdominal Compartment Syndrome (WSACS) recommends using diuretics to remove excess fluids and decrease intra-abdominal pressure (IAP). However, critically ill patients may not tolerate negative fluid balance in the acute phase of their disease and the injured kidney may not respond to diuretics. The aim of this study is to evaluate the influence of furosemide on fluid balance, IAP and kidney function in critically ill patients.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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.
