Intravenous n-3 Fatty Acids and Sudden Cardiac Death in Hemodialysis Patients

Renal FailureChronic

The main purpose of this study is to investigate whether intravenous infusion of a lipid emulsion with a high content of n-3 polyunsaturated fatty acids can improve heart rate variability and ventricular repolarization and reduce ventricular arrhythmias in hemodialysis patients.

Intraoperative Fluid Therapy for Deceased Donor Renal Transplantation

Kidney Failure

Delayed graft function (DGF) is defined as requirement for dialysis in the first week following kidney transplantation. DGF is a common complication occurring in 39% of the deceased donor renal transplants at the investigators' institution with significant cost and outcome implications. The 3 major risk factors for DGF are donor graft characteristics, recipient factors and perioperative management. The most easily modifiable of these factors is perioperative management, in particular intraoperative fluid therapy. The investigators propose to compare the amount of fluid administered using the current standard of care with the fluid administered when optimizing the cardiac output (CO) using Esophageal Doppler Monitoring (EDM) to guide fluid therapy. EDM measures blood flow in the descending aorta, optimizing stroke volume (SV) and cardiac output (CO) by indicating when fluid administration fails to produce an increase in CO.

Use of Bedside Ultrasonography on the Incidence of Acute Renal Failure in High-risk Surgical Patients...

Acute Kidney Injury

The mortality and postoperative complications of high risk surgeries vary in the different series. The management of this group of patients in intensive care unit (ICU) is fundamental to improve these outcomes. The objective of this study will be to evaluate whether the use of bedside ultrasound has an impact on the management of this group of patients with a consequent reduction in the incidence of acute renal failure in ICU and, secondarily, the incidence of associated complications. All adult patients (≥ 18 years old) admitted to ICU at Hospital das Clinicas of UFMG in the immediate postoperative period of major surgery with indication of ICU monitoring will be included and randomly randomized to the control or intervention group. The control group will be conducted by the intensive care physicians in charge without the US, while the second group will be conducted based in US findings. The US protocol will consist of a pulmonary US in four windows in each hemithorax , qualitative assessment of contractility and variation of inferior vena cava diameter. The primary outcome will be the development of acute renal failure as measured by the KDIGO score. Secondary outcomes will be length of ICU and hospital stay, ICU and 28 days mortality, length spent in mechanical ventilation, accumulated water balance, noradrenaline and dobutamine dose. Serum and urinary biomarkers will also be evaluated. Key words: ultrasound, high-risk surgery, intensive care

Sodium Chloride and Contrast Nephropathy

Kidney FailureChronic4 more

This phase II, open, non-inferiority, randomized and controlled clinical trial is aimed to ascertain the incidence of contrast nephropathy in outpatients undergoing CT scan with contrast. Patients will be randomized to receive oral prophylaxis with capsules of sodium chloride and free water ingestion or prophylaxis with sodium chloride 0.9% intravenous solution. The total dose (mmol) of sodium chloride will be the same regardless administration via. The contrast will be iodixanol. Patients >65 years, of both sexes, with at least one of the following criteria: diabetes, stable heart failure or chronic kidney disease (estimated glomerular filtration rate between 30 and 60 ml/min), undergoing CT scan with contrast, and who give written informed consent, will be included in the study. Patients with estimated glomerular filtration rate <30 ml/min, serum potassium <3.5 mEq/L, infusion of iodine contrast in the previous 15 days, administration of nephrotoxic drugs in the previous 72 hours or expected in the following hours after contrast infusion, decompensated chronic conditions (heart failure, chronic obstructive pulmonary disease, hypertension), allergy to iodine contrast, or the presence of hyperchloremia or hypernatremia, will be excluded from the study. Contrast nephropathy will be defined as the increase of serum creatinine >0.3 mg/dL from baseline, or the reduction of estimated glomerular filtration rate (MDRD-4) >25% from baseline, in the first 48 hours after contrast administration.

Intraocular Pressure and Hemodialysis Midwestern Brazil

Renal InsufficiencyChronic1 more

Objective: To evaluate the variation in intraocular pressure in patients with chronic kidney disease, according to the time interval between hemodialysis sessions and to the influence of weight and blood pressure on intraocular pressure. Methods: This was a cross-sectional study in which 78 eyes of 39 patients on hemodialysis, at the Santa Casa de Misericordia de Goiânia hospital, were analyzed in June 2014. Patients were divided into groups according to the days on which they underwent hemodialysis. The mean, standard deviation, and median of the intraocular pressure, blood pressure, and weight were calculated. P-values <0.05 were considered statistically significant.

Interventional Study Targeting Oral Infections in Patients With Chronic Kidney Disease

Mouth DiseasesRenal Insufficiency1 more

This study aims to investigate the prevalence of oral infection in chronic renal disease patients and to examine whether a focused oral hygiene intervention can reduce oral infection leading to reduced systemic inflammatory parameters in chronic renal disease patients in hemodialysis, chronic renal disease patients waiting for kidney transplantation, and chronic renal disease patients who has been transplanted 1-1½ year previously. The results will be compared to a gender- and age-matched healthy control group.

Doppler-based Renal Resistive Index in Assessing Renal Dysfunction Reversibility in ICU Patients...

Acute Kidney Injury

Acute kidney injury (AKI) is common in intensive care unit (ICU) patients and remains associated with a dismal prognosis. The diagnosis of AKI relies on functional criteria (oliguria and serum creatinine elevation), which carry several important limitations. Additionally, the investigators lack biomarker that may predict short term renal prognosis. Doppler-based renal resistive index (RI) measurement is a rapid and noninvasive investigative tool that may hold promise for early AKI detection in ICU patients or in differentiating transient from persistent AKI in selected critically ill patients. Although several studies have suggested adequate performance in predicting short-term reversibility of AKI, most of these studies were performed in limited patient samples. Additionally, a recent study has identified discrepant results regarding its diagnostic performance. The main objective of this large prospective multicentre study is to assess diagnostic performance of Doppler-based renal resistive index in diagnosing persistent AKI in critically ill patients requiring mechanical ventilation.
