About heart valve causing regurgitation Pulmonary effusion related problems

Objective To explore the perioperative risk factors and their effects of pulmonary complications after heart valve replacement. METHODS Taking 356 patients with heart valve replacement from February 2009 to August 201 1 as the study subjects, we analyzed their postoperative factors related to valve replacement and observed their roles in perioperative pulmonary complications. Results ***There were 23 cases of pulmonary complications (6.5%), and the risk factors for pulmonary complications after heart valve replacement included the need for vasoactive drug support (OR = 2.10), secondary chest opening (OR = 2.12), intra-aortic balloon counterpulsation (OR = 2.21), pleural effusion (OR = 2.67), postoperative cerebrovascular accidents (OR = 5.51) and postoperative renal failure requiring renal dialysis. postoperative cerebrovascular accident (OR = 5.51) and postoperative renal failure requiring renal dialysis (OR = 9.89). Conclusion: A number of risk factors increase the incidence of postoperative pulmonary complications after heart valve replacement, especially cerebrovascular accident, phrenic nerve injury and postoperative renal failure requiring renal dialysis. Special attention should be paid to the protection of lung function to minimize the occurrence of complications in these patients.
