肺脓肿的空洞内引流治疗目前已很少采用,但作者认为仍可用于对抗生素耐药,或全身情况差而不能耐受手术治疗的病例。作者报道20例,其中男18、女2例,平均年龄45(15～75)岁。复合性损伤15例(包括颅脑损伤11例,伴不同程度昏迷8例),耳鼻喉科肿瘤2例,大面积灼伤、急性呼吸衰竭、脑血管意外各1例。本组20例中18例长期鼻气管插管作正压通气治疗,包括6例呼气末正压治疗,肺脓肿出现于通气治疗后3～40(平均20)天。方法正、侧位胸片见肺脓肿后,拍断层片准确定位。在透视放大下正确放置引流管,其中1例作双侧引流。以-50cmH_2O压力连续吸引,排空脓腔。每天用少量抗生素作脓腔冲洗3～4次。常用利福平、多粘菌素、庆大霉素。当冲洗液变清,且不再见
Cavity drainage of lung abscess drainage treatment is rarely used, but the authors believe that can still be used for antibiotic resistance, or poor general condition and can not tolerate surgery. The authors report 20 cases, including 18 males and 2 females, with an average age of 45 (15 ~ 75) years old. There were 15 cases of composite injury (including 11 cases of craniocerebral injury and 8 cases of coma with different degrees), 2 cases of ENT tumors, 1 case of extensive burns, acute respiratory failure and cerebrovascular accident. 18 cases of the group of 18 cases of long-term nasal endotracheal intubation for positive pressure ventilation, including 6 cases of positive end-expiratory pressure therapy, pulmonary abscess occurred in ventilation after 3 ~ 40 (average 20) days. Method is, lateral chest radiographs after lung abscess, filming accurate positioning slice. In the perspective of amplification properly placed drainage tube, including 1 case of bilateral drainage. Continuous suction with -50cmH_2O pressure, emptying the abscess. A small amount of antibiotics for abscess wash 3 to 4 times a day. Commonly used rifampicin, polymyxin, gentamicin. When the fluid becomes clear, and no longer see
