Fluid overload is frequent and associated with mortality in critically ill patients, especially those with acute kidney injury. If fluid loading is a cornerstone of a resuscitation strategy, some authors promote an evacuation phase to limit the fluid overload exposure (deresuscitation strategy). In patients with continuous renal therapy, often presenting an inadequate diuresis, it includes the net ultrafiltration setting. A potential side effect of deresuscitation strategy is to induce iatrogenic hypovolemia. We have implemented a perfusion-based protocol to induce systematic early fluid removal on patients after haemodynamic stabilization. We would like to observe the impact on the fluid balance of such a protocol and to explore the recruitment capacity of our centre and exploratory outcomes to lead a future randomized control study.
Study Type
OBSERVATIONAL
Enrollment

After meeting eligibility criteria, patients have a net ultrafiltration of 2mL/kg/h with systematic perfusion monitoring (lactate concentration, central venous saturation, mottling score and capillary refill time) and restrictive input. If the patient presents hypoperfusion (at least to sign), net ultrafiltration is stopped and haemodynamic optimized. If the patient presents pulmonary oedema or right ventricular failure, with venous congestion, ultrafiltration is set at 3mL/kg/h. Ultrafiltration is set between 0.5 and 1mL/kg/h when the following criteria are fulfilled: weight inferior to the admission weight; central venous pressure inferior to 5mmHg; absence of clinical oedema. The haemodynamic status is reevaluated all six hours.
