As a consequence, the occurrence of acute renal failure (ARF), also known as contrast-induced nephropathy, is more frequently seen after the realization of these procedures, representing about 10% of all in-hospital ARF. The importance of preventing this complication is related with its strong association with higher morbidity and mortality rates in patients who present it. A number of drugs and interventions have been studied for preventing contrast-induced nephropathy, including intravenous hydration with normal and hypotonic saline solutions, oral hydration, mannitol, diuretics, dopamine and its antagonists (fenoldopam), calcium antagonists, theophylline, N-acetylcysteine, natriuretic atrial peptide and hemodialysis after or during contrast media administration.\n\nThere is only one study in humans that demonstrates the utility of the sodium bicarbonate to prevent the contrast-induced nephropathy, showing a reduction in the incidence of this complication of about 13.6%. Although this result could seem convincing, its relevance has been questioned because the definition used by the authors as contrast-induced nephropathy was an increase of 25% from basal creatinine. Although when compared, the absolute differences between basal and after-procedure creatinines were not statistically significative, the sample size was small and the participants were low-risk patients to develop contrast-induced nephropathy. It is also important to note that the control group was hydrated with a dextrose 5% solution with 154 mEq of NaCl, although today's most accepted prevention therapy is intravenous hydration with normal saline solution.\n\nComparison: Hydration previously, during and afterwards contrast media administration with normal saline solution (0.9%), compared to hydration previous, during and afterwards contrast media administration with a solution made of normal saline and sodium bicarbonate."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age over 18 years old\n* Indication for coronariography and/or percutaneous coronary intervention\n* Voluntary written consent for the realization of coronariography and/or percutaneous intervention and for the participation in this clinical trial\n* A MEHRAN contrast-induced nephropathy score of six or more\n\nExclusion Criteria:\n\n* Patients with chronic kidney failure requiring any kind of dialysis\n* Patients unable to complete follow-up\n* Multiple myeloma\n* Exposure to contrast 48 hours prior to study\n* Pregnancy\n* Patients unable to give consent\n* Already receiving sodium bicarbonate solutions\n* Receiving contrast media other than non-ionic'}, 'identificationModule': {'nctId': 'NCT00424320', 'briefTitle': 'Clinical Trial of Sodium Bicarbonate to Prevent Contrast-Induced Nephropathy', 'organization': {'class': 'OTHER', 'fullName': 'Instituto Nacional de Cardiologia Ignacio Chavez'}, 'officialTitle': 'Clinical Controlled Trial to Determinate the Role of Sodium Bicarbonate in the Prevention of Contrast-Induced Nephropathy in High-Risk Patients Undergoing to Diagnostic Coronariography and/or Percutaneous Coronary Intervention', 'orgStudyIdInfo': {'id': '06-001'}}, 'armsInterventionsModule': {'interventions': [{'name': 'Sodium bicarbonate', 'type': 'DRUG'}]}, 'contactsLocationsModule': {'locations': [{'zip': '01120', 'city': 'Mexico City', 'state': 'Mexico City (d.f.)', 'status': 'RECRUITING', 'country': 'Mexico', 'contacts': [{'name': 'Jesús Simón Domínguez, PharmD', 'role': 'CONTACT', 'phone': '52+55+52308098'}, {'name': 'Jesús Simón Domínguez, PharmD', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'ABC Medical Center', 'geoPoint': {'lat': 19.42847, 'lon': -99.12766}}, {'zip': '14080', 'city': 'Mexico City', 'state': 'Mexico City (d.f:)', 'status': 'RECRUITING', 'country': 'Mexico', 'contacts': [{'name': 'Emma M Miranda Malpica, MD, PhD', 'role': 'CONTACT', 'email': 'malpicae@yahoo.com.mx', 'phone': '52+55+55732911', 'phoneExt': '1236'}, {'name': 'Emma M Miranda Malpica, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Hilda E Delgadillo Rodríguez, MD', 'role': 'SUB_INVESTIGATOR'}, {'name': 'Juan P Herrera, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Carlos J González-Quesada, MD', 'role': 'SUB_INVESTIGATOR'}, {'name': 'Marco A Peña Duque, MD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Luís J Uribe González, MD, PhD', 'role': 'SUB_INVESTIGATOR'}, {'name': 'Pedro A Reyes López, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': 'Ignacio Chávez National Institute of Cardiology', 'geoPoint': {'lat': 19.42847, 'lon': -99.12766}}], 'centralContacts': [{'name': 'Emma Miranda Malpica, PhD', 'role': 'CONTACT', 'email': 'malpicae@yahoo.com.mx', 'phone': '52+55+55499120', 'phoneExt': '1232'}], 'overallOfficials': [{'name': 'Emma Miranda Malpica, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Ignacio Chávez National Institute of Cardiology'}, {'name': 'Marco A Martínez Ríos, MD, FACC', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Ignacio Chávez National Institute of Cardiology'}, {'name': 'Jorge Gaspar Hernández, MD', 'role': 'STUDY_CHAIR', 'affiliation': 'Ignacio Chávez National Institute of Cardiology'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Instituto Nacional de Cardiologia Ignacio Chavez', 'class': 'OTHER'}}}}
