Introduction

In coronary angiography and PCI, contrast fluids are used. The most common type of contrast fluid used is fluid containing iodine. Iodine can cause contrast induced nephropathy, an acute deterioration in kidney function(> 25% or > 44 micromol/l elevation of creatinine) 2 to 5 days after intravascular fluid administration[1].

Prevention

For prevention of contrast nefropathy, in the Netherlands the guideline issued by the CBO is used[2]. It advised for patients with eGFR < 45 ml/min to hydrate periprocedural. In patients with eGFR < 60 ml/min in combination with risk factors for nephropathy are also advised to hydrate. Risk factors are mentioned in table 1.

Hydration schemes

Hydration in people with normal cardiac function is done by prehydration with 0.9% NaCl 3-4 ml/kg/hr in 4 hours and posthydration with the same scheme (table 2). In patients with cardiac dysfunction the hydration is spread out over 12 hours (in stead of 4 hours) or the fast scheme with sodium bicarbonate (NaHCO3) can be used.
