A study to find whether there is any relationship between difference in blood pressure before heart surgery and blood pressure while on-heart bypass pump and the development of kidney damage after surgery, in patients undergoing valve surgery.

Relationship between difference of preoperative and cardiopulmonary bypass (CPB) mean arterial pressure (delta MAP), and acute kidney injury in cardiac surgical patients undergoing valve surgery

Eligibility

Inclusion criteria

Inclusion criteria: All patients above 18 years of age, with one of the above risk factors, scheduled for elective valve surgery, single, double or CABG with valve surgery on cardiopulmonary bypass will be included in the study.

Exclusion criteria

Exclusion criteria: 1. End-stage kidney disease (CKD class V) 2. Prior kidney transplantation

Design outcomes

Primary

MeasureTime frame
In patients with one risk factor for AKI, undergoing valvular heart surgery: To assess the effect of delta MAP on the incidence of post-operative AKI 24 hrs post-operatively, using the KDIGO classificationTimepoint: 24 hrs

Secondary

MeasureTime frame
1. Assess effect of CPB flow on incidence of post-operative AKI 24 hrs post-op, using KDIGO classification 2. Assess relationship between various post-op variables including mortality, use of IABP, low cardiac output state, significant inotrope use, lengths of ICU and hospital stay and incidence of AKI 3. Assess incidence of requirement of renal replacement therapy in this population 4. Correlate changes in plasma Neutrophil gelatinase-associated lipocalin (NGAL) with delta MAP on CPBTimepoint: 24 HRS
