简要总结

This is an Open-label, Prospective, Multicenter Study to Assess the SAfety of Regional Citrate Anticoagulation Delivered by the multiFiltratePRO system in Adult Patients Requiring Continuous Renal Replacement Therapy (SARCA Study).

详细描述

In short, AKI is a major complication in intensive care patients, often occurring in the context of multiple organ failure, and some of these patients may need CRRT. The major advantage of CRRT is improved hemodynamic stability compared to intermittent HD. Continuous anticoagulation during CRRT may be needed to prevent premature clotting of the circuit and deliver the prescribed dialysis dose. Unfractionated heparin is the most commonly used anticoagulation during CRRT mainly as a result of familiarity, low cost, and ease of administration. But the main drawback is the risk of bleeding.

An alternative technique to avoid systemic anticoagulation is regional extracorporeal anticoagulation with citrate (RCA). The advantages of RCA are improved circuit patency and fewer bleeding complications. The use of RCA may also reduce the ICU staff workload. Studies have shown longer filter running times which reduced circuit change and set-up time. In addition, anticoagulation related bleeding, and CRRT-related blood transfusions were minimized. Therefore, CRRT with RCA might be more economical than conventional anticoagulation.

The study is to explore the possibility of using the multiFiltrate PRO system with the Ci-Ca module, Cifoban® (Trisodium citrate 4%), Calrecia® (Calcium chloride dihydrate), Ci-Ca dialysate K2 and K4, AV1000 (disposable cassette), and multiBic solution in subjects who are critically ill and receiving CRRT in an acute setting.

研究组 & 干预措施

Ci-Ca Arm

Experimental

The study population will include critically ill subjects who are a minimum of 18 years old, in an acute setting, requiring CRRT. the Subjects will receive Regional Citrate Anticoagulation (RCA) which will be delivered by MultiFiltiratePRO system

干预措施: Dialysis (Combination Product)

结局指标

主要结局

Symptoms and systemic ionized calcium level

时间窗: Up to 1 month

Defined as a symptomatic episode of delirium, coma, nausea, vomiting, constipation, muscle weakness, hypertension, bradycardia, deemed attributable to hypercalcemia with a confirmed systemic ionized calcium \> 1.5mmol/L.

Arterial pH measure and bicarbonate level

时间窗: Up to 1 month

Arterial pH \> 7.55 and bicarbonate \> 30 mmol/L in the absence of exogenous bicarbonate administered

Serum sodium (Na) level

时间窗: Up to 1 month

Serum sodium (Na) level \> 150 mmol/L and \> 5 mmol/L rise in systemic Na above the prescribed CRRT fluids. Na level in the absence of hypertonic intravenous Na infusion

Drop in hemoglobin (Hgb)

时间窗: Up to 1 month

Bleeding resulting in more than 2 g/dL drop in hemoglobin (Hgb) in 24-hour period or need for transfusion

Symptoms and total-to-ionized calcium ratio

时间窗: Up to 1 month

Patients with impaired citrate metabolism or citrate overdose can exhibit citrate accumulation. Symptomatic citrate accumulation presents with symptoms of tetany/spasms, seizures, systemic hypocoagulability, hypotension, or cardiac events; and should be confirmed with: 1. A total-to-ionized calcium ratio \> 2.5; OR 2. A total-to-ionized calcium ratio greater than 2.25 together with one or more of the following criteria: 1. an increase in calcium supplementation, 2. decreasing systemic ionized calcium, and 3. metabolic acidosis. When a clinical presentation is possibly associated with an abnormal concentration of systemic ionized calcium or an altered acid-base balance, the labs ({Calcium: systemic ionized calcium, post-filter ionized calcium and total calcium}, bicarbonate, sodium, potassium, magnesium, phosphate) should be checked immediately.

次要结局

  • Circuit life(The life of a circuit is 72 hrs and then it needs to be replaced . Subject participation is upto 1 month.)
