Methods Data of 67 cases of patients with atelectasis diagnosed by type-B ultrasonography and CT were compared, analyzed, and summarized between May 2007 and May 2009. Results The diagnosis coincidence rate which was got by comparing ultrasonography diagnosis of the one side atelectasis and pulmonary lobectomy atelectasis with CT diagnosis was 94.64%, and that of pulmonary segmental atelectasis was 54.55%. Conclusion Type-B ultrasonography can be used as the preferred screening atelectasis diagnosis.
目的:探讨PET-CT模拟定位对非小细胞肺癌合并肺不张适形调强放疗靶区确定的临床价值。方法:对经影像学和病理证实伴有肺不张的非小细胞肺癌12例患者,进行PET-CT模拟定位。根据PET-CT扫描显像结果,分别以GTV CT和GTVPET-CT勾画原发病灶,对用治疗计划系统计算出的两组数值加以比较。结果:GTVCT平均为141 cm3(99~185 cm3),GTVPET-CT平均为113 cm3(60~165 cm3),两者差异有显著性(t=5.497,Plt;0.001)。12例患者原发病灶体积的GTVPET-CT均较GTV CT有不同程度的缩小,平均缩小体积28 cm3(19%)。结论:PET-CT模拟定位,对非小细胞肺癌合并肺不张患者放疗靶区的精确定位具有重要的临床意义。
ObjectiveTo investigate the effect of recruitment maneuver (RM) following fibrobronchoscopy in invasively mechanically ventilated (IMV) patients with excessive airway secretions or foreign body aspiration. MethodsFrom September 2012 to July 2014, 200 eligible patients were randomly assigned to intervention group (n=100) and control group (n=100) . Airway clearance by fibrobronchoscopy was conducted in both the two groups, but RM was subsequently performed only in the intervention group. Outcome measurements included oxygenation index, partial pressure of carbon dioxide (PaCO2), heart rate (HR), air way resistance (Raw) and dynamic lung compliance (Cdyn) before and 2 hours after treatment, and duration of IMV and Intensive Care Unit (ICU) stay were also analyzed. ResultsAfter treatment with fibrobronchoscopy, oxygenation index [intervention vs. control: (291.14±38.49) vs. (241.39± 35.62) mm Hg (1 mm Hg=0.133 kPa)], PaCO2 [(41.65±7.73) vs. (38.87±7.97) mm Hg] and Cdyn [(48.94±11.21) vs. (39.59±10.98) mL/cm H2O (1 cm H2O=0.098 kPa) ] were significantly increased, while HR [(95.41±20.59) , vs. (106.47±19.11) beats/min] and Raw [(17.87±8.32) vs. (23.98±7.88) cm H2O/(L·s)] were significantly decreased in both groups (P < 0.01) . Duration of IMV and ICU stay in the intervention group were (15.72±6.42) and (19.85±8.12) days respectively, while in the control group were (20.49±7.21) and (27.87±10.33) days. Compared with the control group, patients in the intervention group had lower Raw, duration of IMV and ICU stay, and higher Cdyn, oxygenation index, and PaCO2 (P < 0.01) , but no significant difference was found in HR (P > 0.05) . ConclusionIn mechanically ventilated patients with excessive airway secretion or foreign body aspiration, recruitment maneuver following fibrobronchoscopy is of great clinical importance, due to the decrease of the duration of mechanical ventilation and ICU stay by re-inflating the collapsing alveoli, improving pulmonary ventilation and gas exchange, lung compliance and diffusion capacity.
目的探讨肋骨骨折导致的创伤性肺不张治疗中应用电子支气管镜肺段灌洗治疗的效果 方法回顾性分析新疆医科大学第六附属医院2009年10月至2013年4月肋骨骨折导致创伤性肺不张73例行电子支气管镜肺段灌洗治疗患者的临床资料,其中男52例、女21例,年龄29~83(36± 5)岁。按治疗方式将患者分为两组:灌洗组(37例)行电子支气管镜肺段灌洗,对照组(36例)采用肺不张的常规治疗。比较两组临床效果。 结果灌洗组呼吸频率及心率减慢,动脉血氧饱和度升至95%以上,肺复张明显好于对照组,差异有统计学意义(P < 0.05)。 结论电子支气管镜肺段灌洗治疗肋骨骨折导致的创伤性肺不张直视下诊断明确,起效快,创伤小,疗效确切。
Central lung cancer is a common disease in clinic which usually occurs above the segmental bronchus. It is commonly accompanied by bronchial stenosis or obstruction, which can easily lead to atelectasis. Accurately distinguishing lung cancer from atelectasis is important for tumor staging, delineating the radiotherapy target area, and evaluating treatment efficacy. This article reviews domestic and foreign literatures on how to define the boundary between central lung cancer and atelectasis based on multimodal images, aiming to summarize the experiences and propose the prospects.
