简要总结
This is a prospective observational study to find out the role of measuring renal resistive index in predicting acute kidney injuryin patients undergoing living donor liver transplantation surgeries. The renal resistive index (RRI) is a non-invasive ultrasonographic Doppler tool which measures blood flow velocity in intra-parenchymal renal arteries. Normal values are reported between 0.60 to 0.70 with the difference between both kidneys being mostly less than 5%. Tacrolimus is one of the drugs used in immunosuppressive therapy of organ transplant recipients and its potency has been proven in treating early graft dysfunction, graft loss, acute rejection, new onset diabetes after transplant and hypertension.
Study population includes those who are above 18years of age. Total sample size is 100. These patients RRI is measured pre operatively and follow up til POD 05 along with tacrolimus trough level, renal function biochemical parameters, eGFR, urine output etc.
Our secondary objective is to find the association with tacrolimus trough levels,eGFR along with RRI in predicting AKI.
