Hydration Guided by Remote Dielectric Sensing (ReDS) System for Preventing Acute Kidney Injury in Elderly Patients With Renal Insufficiency for Coronary Angiography and Intervention

Condition(s) studied

Investigational drug(s) / intervention(s)

Tailored hydration guided by ReDS system: If initial lung water index is ≥35%, the hydration rate is 1ml/kg/h; If the initial lung water index is \<35% but ≥20%, the hydration rate is 2ml/kg/h; If the initial lung water index is \<20%, the hydration rate is designed to 5ml/kg/h. We re-check the lung water index after the contrast procedure. If the lung water index is \>35% or if there is a more than 2-fold increase in the lung water index compared to pre-procedure, adjust the fluid infusion rate to 0.5ml/kg/h. If the lung water index after the contrast procedure is ≥20% but \<35%, adjust the fluid infusion rate to 1ml/kg/h. If the lung water index after the contrast procedure is still \<20%, adjust the fluid infusion rate to 5ml/kg/h.

Study summary

Explore the effectiveness and safety of tailored hydration guided by lung water index monitor system for prevention of acute kidney injury after percutaneous coronary intervention for elderly patients with renal insufficiency.
