目的 评价地佐辛配伍丙泊酚联合喉罩用于无痛纤维支气管镜检查的效果。 方法 将2012年10月－12月拟行纤维支气管镜检查，且按美国麻醉医师协会分级Ⅰ或Ⅱ级的60例患者，随机分为芬太尼组（F组）、地佐辛组（D组）、生理盐水组（N组）,每组20例。采用双盲法给药，静脉注射芬太尼（10 μg/mL）或地佐辛（1 mg/mL）或生理盐水0.1 mL/kg，5 min后3组缓慢静脉注射丙泊酚2 mg/kg诱导后置入喉罩，术中保留自主呼吸，持续泵入丙泊酚4～6 mg/（kg·h）维持麻醉，观察3组患者诱导前（T0）、诱导后时（T1）、纤维支气管镜操作时（T2）、术毕时（T3）及拔除喉罩时（T4）的生命体征，记录丙泊酚总用量、苏醒时间、苏醒时的呼吸道疼痛视觉模拟评分（VAS），记录术中及术后有关并发症的发生情况。 结果 与N组相比，D、F两组丙泊酚总用量减少、苏醒时间缩短，头昏及术中体动发生率、VAS评分明显降低（P＜0.05）；呼吸暂停的发生率D组最低（P＜0.05）；恶心、呕吐的发生率F组最高（P＜0.05）。 结论 地佐辛配伍丙泊酚联合喉罩用于无痛纤维支气管镜检查，麻醉效果满意，术后镇痛效果好，值得临床推广。
Objective To investigate the manifestations, diagnosis and treatment of tracheobronchopathia osteochondroplastica ( TO) . Methods Two cases of TO were described and 76 cases in the medical literature after 2000 were reviewed. Results TO usually manifests in adults, and affects both genders. The clinical presentation of TO is nonspecific. Bronchoscopy remains the gold standard for diagnosing this condition. Hard sessile nodules arising from the anterior and lateral walls of the airway,typically sparing the posterior membrane, are classic appearance that can be easily recognized. The CT scan is more sensitive and specific, which plays an important role in the diagnosis of TO. Bronchial biopsies disclose the abnormal presence of cartilage and bone tissue in the bronchial submucosa. To date there is nospecific treatment for the disease. Only a minority of cases develop into significant upper airway obstruction and require invasive procedures to remove or bypass the obstacle on affected airways. Conclusions TO is a stable or slowly progressive benign disease. Chest computed tomography and fiberoptic bronchoscopy are thebest diagnostic procedures to identify TO.
Objective To compare the diagnostic value of sterile sputumsuction tube with protected specimen brush in mechanically ventilated patients with serious lung infection, and explore the safety and efficacy of bronchofibroscope combining mechanical ventilation in the treatment of severe lung infection.Methods Seventy-four severe lung infection patients with invasive mechanical ventilation support were recruited in the study. Based on the routine treatment, the subjects were randomly divided into a control group received only mechanical ventilation, and a treatment group received sputum aspiration and bronchial lavage by bronchofibroscope combiningmechanical ventilation. Lower respiratory tract secretion was collected to analyze the bacterial etiology with sterile sputum suction tube in the control group, and with protectedspecimen brush in the treatment group. Results The positive rate of sputum suction tube and protected specimen brush was 70. 27% and 75. 68% , respectively, with no statistical difference between the two groups ( P gt; 0. 05) . The PaO2 of the treatment group increased and PaCO2 decreased obviously after sputum aspiration and bronchial lavage by bronchofibroscope ( P lt; 0. 01) . The total effective rate was also highly increased, and the heart rate and respiration were stable in the treatment group. The time of mechanical ventilation and the length of ICU stay were all shortened in the treatment group compared with the control group. Conclusions Sterile sputum suction tube can not only acquire accurate pathogen, but also is a simple and economical method for patients with severe lung infection with mechanical ventilation. Sputum aspiration and bronchial lavage with bronchofibroscope combining mechanical ventilation are effective and safe treatment for patients with severe lung infection.
Abstract： Objective To evaluate the effect of 100% carbolic acid via bronchofiberscope for the treatment of bron- chopleural fistula. Methods We retrospectively analyzed clinical data of 12 patients with postoperative bronchopleural fistula in Liaoning Tumor Hospital from February 2009 to March 2012. There were 11 male patients and 1 female patient with their average age of 58.0 （45-71） years. All the patients had primary lung cancer, including squamous cell carcinoma in 8 patients and adenocarcinoma in 4 patients， central lung cancer in 8 patients and peripheral lung cancer in 4 patients. Three patients were after right total pneumonectomy， 6 patients were after left total pneumonectomy， 2 patients were after right middle and lower lobectomy， and 1 patient was after left upper lobectomy. All the patients received 100% carbolic acid instillation via bronchofiberscope， and 0.5-1.0 ml carbolic acid solution was instilled on the mucosal surface around the fistula each time. The presence of bubbles in thoracic drainage was observed. If some bubbles remained, such treatment was repeated after 1 week. The effectiveness was analyzed. Results All the 12 patients were cured after carbolic acid treatment, including 8 patients after 5 times of carbolic acid instillation， 2 patients after 7 times of carbolic acid instillation， and 2 patients after 2 times of carbolic acid instillation. The average time for fistula closure was 33 days. All the patients were treated in our outpatient clinic except 2 patients who were too weak but cured after 42 days and 50 days of hospitalization respectively. Conclusion The use of 100% carbolic acid instillation via bronchofiberscope can provide satisfactory clinical outcomes for the treatment of bronchopleural fistula.
Abstract： Objective To evaluate clinical outcomes of painless flexible fiberoptic bronchoscopy in the treatment for pulmonary complications in postoperative pediatric patients with congenital heart diseases. Methods We retrospectively analyzed clinical data of 58 patients who received fiberoptic bronchoscopy for pulmonary complications after surgical repair for atrial septal defect， ventricular septal defect， tetralogy of Fallot， double outlet right ventricle or transposition of the great arteries in First Affiliated Hospital of Harbin Medical University From August 2009 to February 2012. There were 26 male patients and 32 female patients with their age ranging from 20 days to 2 years. Olympus xp-60 fiberoptic bronchoscopy was used for removal of airway secretions and bronchial alveolar lavage under anesthesia with propofol， fentanyl and lidocaine. Pulse oximetry， respiratory sound and chest X-ray changes were observed. Results The examination time of painless fiberoptic bronchoscopy was 10-25 minutes in the 58 patients. After removal of airway secretions by fiberoptic bronchoscopy， their respiratory status improved significantly， pulse oxygen saturation increased by 5%-12%， and their pulmonary crackles were significantly reduced. In 29 patients with atelectasis， their pulmonary lobes demonstrated significant reexpansion in chest X-ray reviews on the next day after fiberoptic bronchoscopy， and 8 patients received another fiberoptic bronchoscopy treatment on the next day to achieve complete pulmonary reexpansion. One patient with severe pulmonary hypertension （PH） stayed in intensive care unit （ICU） for 6 days， 3 patients with transposition of the great arteries stayed in ICU for 5 days， 3 patients with double outlet of right ventricle and moderately high PH stayed in ICU for 4 days， and all the other patients were discharged from ICU within 48 hours after admission. There was no severe complication related to fiberoptic bronchoscopy， except 2 patients with minor nasal mucosa bleeding who were cured with hemostatic drugs and local compression. Conclusion Painless flexible fiberoptic bronchoscopy can significantly enhance clinical outcomes and shorten ICU stay for postoperative pediatric patients with congenital heart diseases.
