Protocol summary

Study aim
The purpose of this study was to compare the effect of CO2 and contrast media on the occurrence of nephropathy in patients undergoing angiography or angioplasty of the lower extremity.
Design
A single-blind, parallel controlled, randomized clinical trial is performed on 166 eligible patients.
Settings and conduct
This study is single blind and patients are not aware of the type of intervention.Both groups receive Ejection Fraction (EF) -based hydration 12 hours before the procedure and 6 hours after the procedure. Patients in the co2 group receive a maximum of 60 cc of CO2 gas with a maximum of 20 cc of contrast agents (if needed) during diagnostic or therapeutic action. The contrast-receiving group will be diagnosed or treated with a maximum of 500 cc through the artery sheath.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Age over 18 years Estimated Glomerular filtration rate (GFR) greater than 30 ml / min /1.73 m2 based on Modification of Diet in Renal Disease (MDRD) equation. Exclusion criteria: Contact contrast over the past month Patients with intracardiac shunt, History of kidney or heart transplantation, More than 15% change in serum creatinine level over the past two days, Patients undergo regular hemodialysis, Patients with a history of proteinuria and Cirrhotic patients.
Intervention groups
Patients groups: 1.angiography or angioplasty of the lower extremities with CO2 gas 2.angiography or angioplasty of the lower extremities with contrast media.
Main outcome variables
Contrast induce acute kidney injury

Randomization description
Simple randomization The computer generates random numbers between 0 and 1. If the random number is less than 0.500, the person enters group T. If the random number is greater than 0.500, the person enters group C.
Blinding (investigator's opinion)
Single blinded
Blinding description
After obtaining informed consent, patients are divided into two groups based on random numbers, but the patients do not know which groups they belong to.
