Peripheral Perfusion Targeted Fluid Management

January 3, 2014 updated by: ME van Genderen, Erasmus Medical Center

Peripheral Perfusion Targeted Fluid Management in Critically Ill Patients: a Pilot Study

  • Impaired peripheral perfusion is related to worse outcome in critically ill patients. Although this is known, these parameters have never been used as target for hemodynamic therapy.
  • We hypothesize that targeting of fluid administration on parameters of peripheral perfusion might prevent excessive fluid administration, leading to less formation of tissue edema, less respiratory dysfunction and shorter duration of mechanical ventilation in critically ill patients.

Detailed Description

Rationale: Currently, fluid administration of critically ill patients is aimed at optimizing conventional hemodynamic parameters such as stroke volume and cardiac output. Fluid is infused repeatedly until patients become "non-responsive", i.e. cardiac output does not increase anymore. However, the ultimate goal of hemodynamic therapy should be to improve peripheral (i.e. tissue) perfusion. Recently we have shown that 1) increasing stroke volume does not always have an effect on peripheral perfusion and 2) that peripheral perfusion is not impaired when stroke volume can still be increased with fluid infusion. Furthermore, repeated administration of fluid in order to reach a maximum cardiac output can lead to an enormous accumulation of fluid in the patient. This leads to formation of lung edema and respiratory dysfunction and is associated with prolonged mechanical ventilation and ICU-stay. Recently, techniques have been developed which allow bedside assessment of peripheral perfusion. Although impaired peripheral perfusion was related to worse outcome, these parameters have never been used as target for hemodynamic therapy.

Objective: To study whether peripheral perfusion targeted fluid management (PPTFM) leads to less fluid administration, improved respiratory function and shorter mechanical ventilation.

Study design: The study is a pilot study and is designed as a randomized controlled trial. The study will be conducted as a single-center study at the Intensive Care of the Erasmus Medical Center.

Study population: We aim to include 40 adult patients who are admitted to the Intensive Care with hemodynamic instability (defined as mean arterial pressure < 65 mmHg and an arterial lactate concentration > 3.0 mmol/l) due to severe sepsis and septic shock.

Intervention: In the intervention group fluid management is targeted on peripheral perfusion parameters while in the control group fluid is administered in order to optimize cardiac output.

Main study parameters/endpoints: The main study endpoints are daily fluid balance and duration of mechanical ventilation.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There is a possible risk that in the treatment group the patients will remain hypovolemic. To ensure that this will not occur, fluids will be administrated in this group, irrespective of peripheral perfusion parameters, until cardiac index is 2,5 L/min/m2. Assessment of peripheral perfusion is performed with non-invasive optical techniques that impose no burden to the patient.

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.

Arms and Interventions

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
NO_INTERVENTION: Control
The fluid management algorithm of the control group is based on the standard care procedure of our ICU as recommended in guidelines: the patient's fluid status is assessed by performing a fluid challenge with a bolus of 250 ml colloids. When the patients is fluid responsive (i.e. showing an increase in stroke volume > 10% ) he will receive an additional bolus of 250 ml of colloids. After each fluid challenge, patients will be revaluated for fluid responsiveness to access need of further fluid administration.
EXPERIMENTAL: PPTFM
The fluid management algorithm of the intervention group uses identical therapy (i.e. fluids) yet targeted at different endpoints (i.e. peripheral perfusion parameters). After evaluation of peripheral perfusion, only patients with a "bad peripheral perfusion" (i.e. 3 out of 4 criteria considered as bad) will receive a fluid challenge, the same way as in the standard care procedure (i.e. bolus of 250 ml of fluid). After each fluid challenge, patients will be re-evaluated for peripheral perfusion to access further need in fluid challenges. To ensure that no hypovolemia will occur in the intervention group, fluid will be administered irrespectively of peripheral perfusion parameters, if cardiac index falls below a value of 2,5 L/min/m2.
