气管内长期插管引起支气管狭窄,一般并不常见,但对婴幼儿来说,则与显著的死亡率有关。作者用氩激光治疗威胁生命的小儿获得性支气管狭窄8例,取得了满意的效果。病人与方法患婴4男4女,年龄3周至2岁,因慢性肺疾病或上呼吸道梗阻行持续插管导致至少有90%(7/8例)以上的支气管腔阻塞。治疗时的全部操作采用全麻和肌松剂。以3.5mm的软支气管镜谨慎地插入。用300或600μm石英激光纤维与氩激光相连接。通过支气管镜能恰好地看到纤维端。在这种方式下。可使激光的能量得到正确地控制而传递到预定的部位。有2个小婴儿激光纤维通过一3 mm的硬支气管镜穿过的。全部病例,支气管镜放在一个内窥镜
Long-term endotracheal intubation caused by bronchial stenosis, are generally not common, but for infants and young children, and significant mortality. The authors used argon laser treatment of life-threatening pediatric acquired bronchoconstriction in 8 cases, and achieved satisfactory results. Patients and Methods Infants with 4 males and 4 females, aged 3 weeks to 2 years, and at least 90% (7/8) of bronchoconstrictive obstruction due to persistent intubation due to chronic lung disease or upper airway obstruction. The whole operation of treatment with general anesthesia and muscle relaxants. Insert softly with a 3.5mm bronchoscope. A 300 or 600 μm quartz laser fiber is connected to an argon laser. Through the bronchoscope can just see the fiber end. In this way. Laser energy can be properly controlled and delivered to a predetermined site. There are 2 small baby laser fibers passing through a 3 mm hard bronchoscope. All cases, bronchoscopy on an endoscope
