     方法:2001年11月至2006年11月河北医科大学附属第四医院呼吸内科收治的气胸患者60例。男性53例,女性7例,年龄范围19~70岁,平均年龄40±14岁。入选条件:(1)符合自发性气胸诊断标准;(2)经胸腔闭式引流术治疗1 w后无效,患者同意进入本研究;(3)无严重心、肺功能障碍;(4)无纤维支气管镜检查的禁忌症。60例自发性气胸患者中,原发性气胸33例,继发性气胸27例;继发性气胸中慢性阻塞性肺病(COPD)14例、支气管扩张3例、肺癌5例、陈旧性肺结核4例、其他1例。根据气胸类型分类:闭合性气胸41例,开放性气胸14例和张力性气胸5例。
     实验器材:(1)双腔球囊漂浮导管(Swan-Ganz catheter)外径5~9 F,长60~110 cm,其远端包绕乳胶球囊,充气后直径0.6~2.2cm。近端有两个开口,一是带阀门并通向球囊;一是不带阀门通向球囊前端的管道,用于气道内注气、测压和注药。(2)纤维支气管镜专用球囊导管(型号:Bronchus blocker 170,德国Ruesch公司),导管长170 cm,外径2 mm;其远端包绕乳胶球囊(最大直径可膨胀2.0 cm)。近端阀门系统可与导管分离,阀门系统有两个开口,一个通向导管远端,用于注药和注入气体定位,另一个带阀门通向远端球囊。(3) Olympus BF-1T60型纤维支气管镜,其工作通道2.8 mm。(4)供纤维支气管镜应用的生物蛋白胶注射专用导管,医用生物蛋白胶。(5)心电监护仪、引导钢丝、压力表(脑脊液压力表)和手术丝线。
     60例患者随机分为A组对照组(应用纤维支气管镜专用球囊导管):30例,沿纤维支气管镜工作道插入纤维支气管镜专用球囊导管,将球囊置于可疑气胸肺破裂所属叶、段或亚段支气管,球囊充气、阻断气道气流,然后胸腔持续负压吸引,观察胸腔闭式引流瓶内气体引流情况,定位气胸肺破裂所属支气管;B组(应用双腔球囊漂浮导管):30例,采用丝线将双腔球囊漂浮导管固定于纤维支气管镜,并行气道内插入,将球囊置于可疑气胸肺破裂所属叶、段或亚段支气管,球囊充气,封堵支气管管腔,向充气球囊远端气道注气、测压,定位气胸肺破裂所属支气管。两组患者确定气胸肺破裂所属支气管后,均采用经纤维支气管镜活检孔插入专用的双腔医用生物蛋白胶注射导管,由支气管远端缓慢注入液态生物蛋白胶A胶和B胶,蛋白胶用量以完全封堵段或亚段支气管为宜,一般1~3支之间,观察引流管气体排出情况和评价两组疗效。
     两组患者于治疗前和治疗后(术后2小时)监测并记录静息状态下的生命体征和血氧饱和度(T、P、R、BP和SaO2)。记录两组定位及粘堵结果、操作时间、住院时间和不良反应。

Objective: To evaluate the efficacy and safety of localization technique with double-lumen balloon floating catheter (Swan-Ganz catheter) under the lead of bronchofibroscope in the treatment of pneumothorax, comparing with the catheter special for bronchofibroscope (Fogarty catheter).
     Methods: 60 patients with pneumatothorax were studied from November 2001 to November 2006. male 53 and female 7, ages ranging from 19 to 70 years old and the average age was 40±14. The selecting standards: (1) all the patients were suffered with spontaneous pneumothorax; (2) after the treatment of closed drainage of thoracic cavity for 1 week but had no effect, and willingly accepted the treatment of Swan-Ganz catheter;(3) without serious functional disorder of heart and lung system; (4) without the contraindications of bronchofiberscopy. These 60 patients include 33 idiopathic pneumothorax, 27 secondary pneumothorax. Among the patients with secondary pneumothorax, chronic obstructive pulmonary disease was 14, bronchiectasia was 3, lung cancer was 5, obsolete pneumonophthisis was 4 and others was 1. Pneumatothorax type: closed pneumothorax 41, open pneumothorax 14 and tension pneumothorax 5.
     Experiment equipment: (1)Swan-Ganz catheter, outer diameter is 5~9F, length is 60~110cm and it's anterior extremity was encasemented with a balloon. The diameter after aerating is 0.6~2.2cm. There were two gabs in the proximal end, the one lead to the balloon with spigot; the other one lead to the conduit without spigot in front of the balloon which was used to pour gas, measure pressure and inject drug. (2) Catheter special for bronchofibroscope (pattern number: Bronch blocker 170, German Ruesch company), tube length 170cm, external diameter 2 mm; anterior extremity was encasemented with a balloon (maximum diameter 2.0 cm). The spigot system could be separated from conduit and had two debouches, the one lead to the anterior extremity of conduit in order to pour drug and localization, the other one with spigot lead to the balloon. (3) Olympus BF-1T60 bronchofibroscope, the working passageway was 2.8 mm. (4) The special conduit for injecting fibrin glue, medical fibrin glue. (5) Electrocardiogram monitor, aiming steel-wire, pressure gage (spinal fluid pressure gauge) and surgical thread .
     All the patients were divided into two groups randomly: control group (group A) and the study group (group B). Group A (fogarty catheter): 30 patients, fogarty catheter were inserted into the lung along the bronchofibroscope working way and placed the balloon on lobes of lung, segment or deutosegmental bronchus in that rupture exist, filling gas, blocked air current and made the cavitas thoracis negative pressure aspiration continuously. At last, the ruptured bronchus was aligned by observing the gas draining in drainage bottle. Group B (Swan-Ganz catheter): 30 patients, using the surgical thread to fix Swan-Ganz catheter and bronchofibroscope, then inserted into the airway together, placed the balloon on lobes of lung and segmental bronchus that rupture exist. At last, filling gas, blocking airway, pouring gas to the distal end, measuring pressure and align the ruptured bronchus. After ascertaining the ruptured bronchus, the special double-lumen injection catheter for fibrin glue was inserted into the working channel of bronchofibroscope. Fibrin glue A and B were infused into the bronchus distal end slowly. The dosage was proper to block the segmental bronchus completely.
     Then compare the result of localization, running time, adverse reactions between the two groups, and evaluate the effectiveness of the two methods in blocking the bronchus Results
     1 There was no statistically significance between the two groups in age, sex and type of the pneumothorax.
     2 The achievement ratio of localization and sealing Group A: 20 of 30 patients were succeeded in localization. 16 of 20 patients were succeeded in sealing at the first time and 2 were succeeded in sealing at the second time. Group B: 26 of 30 patients were succeeded in localization. 21 of 26 patients were succeeded in sealing at the first time and 3 were succeeded in sealing at the second time. No statistically significance between the two groups (P>0.05).
     3 The localization result of closed pneumothorax patients, group A: 10 of 20 patients were succeed in localization. Group B: 17 of 21 patients were succeed in localization, the difference of localizing ruptured bronchus between the two groups was statistically significant (P<0.05).
     4 The average running time and average stay of the two groups
     4.1The average running time A: 14.3±1.2 min, B: 14.8±1.3 min, and no statistically significance between the two groups (P>0.05).
     4.2The average stay A: 14.3±2.4 d, group B: 13.8±2.1 d, there was no statistically significance (P>0.05).
     5 Comparison of the security between the two groups
     5.1 The variation of vital sign
     The vital sign and saturation of blood oxygen were monitored respectively in the pre-treatment and post-treatment (two hours after the operation). There was no statistically significance between the two groups in post-treatment (P>0.05); and there is no statistically significance between the two group in pre-treatment (P>0.05); group A: there was statistically significant between the pre-treatment and post-treatment (P<0.05); group B: there was statistically significant between the pre-treatment and post-treatment (P<0.05).
     5.2 The adverse effect
     Group A: chest complaint 1, pneumonia 1 and fever 2 and pulmonary atelectasis 1. Group B: fever 1, pulmonary atelectasis 1.
     Conclusion
     1 Through this research, the method that using surgical thread to fix the double-lumen balloon floating catheter and bronchoscope, and further inserted into the airway together, pouring the gas to the airway and measuring pressure to locate the ruptured bronchus was used. And it comes to a new kind of convenient, safe and inexpensive method.
     2 As to the closed pneumothorax, the method which was using the double-lumen balloon floating catheter and bronchoscope inserted into the airway together is sensitive than the usage of the Fogarty catheter.
