Fatores de risco no desenvolvimento de insuficiência renal aguda no pós-operatório de cirurgia cardiovascular

Abstract

The objective of this study was to identify risk factors for acute renal failure (ARF) in patients undergoing cardiovascular surgery with cardiopulmonary bypass. METHODS: Retrospective analytical study with primary data of 157 patients who underwent cardiopulmonary bypass surgery (CPB) at the Ana Nery Salvador-BA Hospital, from January to December 2017. RESULTS: A total of 114 patients with male prevalence were included (54.73%), with predominance of valve-only surgery (84.21%). Acute renal failure occurred in (16.66%) of the 114 patients studied. Risk factors associated with ARF were anoxia time 155.5 + - 84.207 in the ARF group (vs. 101.1 + - 38.25 in the group without ARF), CPB time 171.83 + - 70.3 in the ARF group. group with ARF (vs. 120.28 + - 38.25 in the group without ARF), previous AMI (with ARF 26.32%, without ARF 5.3%), intra or postoperative bleeding (with ARF 52.63 %, without ARF 22.1%), and previous cardiac surgery (with ARF 57.89%, without ARF 27.36%). CONCLUSION: Acute renal failure after cardiovascular surgery is a frequent complication. Being independent risk factors: time of anoxia, time of CPB, previous AMI, previous cardiac surgery and intraoperative or postoperative bleeding.
