Contrast-induced nephropathy: identification of risks to promote good practices

Objective: To identify the risk factors for contrast-induced nephropathy (CIN) in patients who underwent percutaneous transluminal coronary angioplasty (PTCA) and discuss the nursing care from the perspective of good practices in order to minimize it. Method: Cross-sectional, retrospective, quantitative study carried out from January to December 2015, using documentary analysis through medical records. Results: Eighty-seven medical records were selected. The male sex prevailed with 67.8% (59), with a mean age of 58.8 ± 10.4. It was seen that 6 patients (6.8%) used contrast injections between 100 ml or more and 32 (36.8%) presented alterations in hematocrit values. Concerning the risk for nephropathy, 24 (27.6%) presented moderate to very high risk. Conclusion: Risk factors for CIN are common in patients who undergo PTCA. Thus, discussing nursing care that can collaborate in the identification and prevention of kidney injury is strategic and contributes to good practices.
