162例开胸手术后胸腔感染的危险因素分析

目的 调查开胸手术后患者胸腔感染的危险因素,探讨有效的预防和控制措施.方法 对162例开胸手术后患者的胸水或胸腔引流管前端2 cm进行细菌培养,并对其进行回顾性调查分析,提出相应的预防措施.结果 162例开胸手术后患者胸腔感染的发生率为12.96％,感染与手术时间、术后污染、肺部病灶蔓延、胸管留置时间有显著相关性；与患者年龄、性别、胸管类型等因素无关；检出病原菌19株,以铜绿假单胞菌为主,占26.31％,其次为金黄色葡萄球菌,占21.05％.结论 开胸手术后患者胸腔感染与手术时间、术后污染、肺部病灶蔓延、胸管留置时间密切相关,应积极采取有效措施,降低开胸手术后患者胸腔感染的发生率.

Risk factors for chest infections in 162 patients after thoracotomy

OBJECTIVE To investigate the risk factors for chest infection after thoracotomy,and discuss the effective preventive and control measures.METHODS Bacterial culture was performed for pleural effusion or 2cm length of the head of chest drainage tube from 162 patients after thoracotomy,and the results were retrospectively analyzed.The corresponding preventive measures were proposed.RESULTS Of 162 patients who underwent thoracotomy,the rate of chest infection after thoracotomy was 12.96%,which was significantly correlated with the surgery time,pollution,spread of lung lesions and chest tube retention time,and was unrelated to age,gender,type of chest tube and so on.19 strains of pathogenic bacteria were detected,and Pseudomonas aeruginosa was the major species,accounting for 26.31%,followed by Staphylococcus aureus,accounting for 21.05%.CONCLUSION The chest infection in patients after thoracotomy is closely related to the surgery time,postoperative pollution,spread of lung lesions and chest tube retention time.We should take effective measures actively to reduce the incidence of chest infections after thoracotomy.
