A transtracheal catheter (TTC) (Scoop) was implanted in 24 patients (19 men, 5 women) with a mean age of 64 +/- 9 (47 to 78) years. The pO2 was 6.78 +/- 1.65 kPa. Two patients suffered from pulmonary restriction, 22 from severe COPD with a FEV1 of 880 +/- 165 ml. Purulent tracheitis developed in six patients. The pre-Scoop catheter had to be removed in three. In four patients, bronchoscopic aspiration of mucus plugs adhering to the tip of the TTC was necessary. In one patient, the TTC was removed after an uneventful course due to patient's discomfort; another patient no longer qualified for LOT. 19 patients were using the TTC without major problems. Of those, five have died due to severe lung disease. By using TTC, oxygen consumption is halved for the same degree of oxygenation. 12 are using a demand valve device (Oxymatic), which allows a further conservation of oxygen. Patients prefer LOT by a TCC for cosmetic reasons and lack of nasal discomfort.
24例患者（19例男性，5例女性）植入了经气管导管（TTC）（Scoop型），平均年龄64±9（47至78）岁。动脉血氧分压为6.78±1.65kPa。2例患者存在肺限制性疾病，22例患有重度慢性阻塞性肺疾病（COPD），第一秒用力呼气容积（FEV1）为880±165ml。6例患者发生了化脓性气管支气管炎。3例患者的Scoop导管置入前的导管必须移除。4例患者需要通过支气管镜抽吸附着于TTC尖端的黏液栓。1例患者在病情平稳后因患者不适而移除了TTC；另1例患者不再符合长期氧疗（LOT）标准。19例患者使用TTC没有出现重大问题。其中，5例患者因严重肺部疾病死亡。使用TTC时，在相同氧合程度下耗氧量减半。12例患者使用按需阀装置（Oxymatic），这可以进一步节省氧气。由于美观原因以及没有鼻部不适，患者更喜欢通过TCC进行长期氧疗。
