Multivariate Analysis Of Pulmonary Infection After Off Pump Coronary Artery Bypass Grafting

Objectives: Off-pump coronary artery bypass grafting(OPCABG)has become the surgical treatment of coronary heart disease,especially the standard method of revascularization treatment of severe coronary artery disease.Postoperative pulmonary infection is one of the common complications of OPCABG.It is of great significance to improve the prognosis of patients by studying related risk factors,seeking to do secondary prevention,and adjusting perioperative treatment strategies.Method:The subjects of the study were patients who underwent OPCABG at the Second Hospital of Hebei Medical University from October 2015 to October 2017.Record patient’s information and refer to the criteria of the Centers for Disease Control and Prevention(CDC)for diagnosis of lung infections.conduct statistical analysis.Results: Of the 764 patients in the study,31 had pulmonary infections with an incidence of 4.1%.Postoperative pulmonary infections were significantly associated with mortality.Postoperative tracheal intubation for more than 24 hours,postoperative atrial fibrillation,interventricular septum thickening,increased left ventricular diameter,increased left ventricular diameter,and decreased ejection fraction were risk factors for pulmonary infection after OPCABG.Multivariate Logistic regression analysis showed that the intubation time of tracheal intubation was more than 24 hours and postoperative atrial fibrillation was closely related to postoperative OPCABG pulmonary infection.Conclusion:Extracting the trachea intubation as early as possible will help reduce the incidence of postoperative pulmonary infection.Postoperative atrial fibrillation is closely related to postoperative pulmonary infection.Preoperative ul-trasound results have a predictive effect on postoperative pulmonary infection.Preoperative cessation of smoking patients,the incidence of postoperative pulmonary infection can be no significant difference with non-smoking patients.In diabetics with well-controlled preoperative blood glucose control,the incidence of postoperative pulmonary infections may not be significantly different from non-diabetics.Perioperative management may reverse the effects of high-risk factors.
