A method of percutaneous intratracheal catheter (PITC) was studied for postoperative respiratory care and prevention of postoperative pulmonary complications. The oxygen was insufflated through the catheter persistently at 2-4 liters per minute. Successful results were obtained in 20 patients who were in poor pulmonary risk such as older age, major operation and pre-existing pulmonary insufficiency, revealing more effectiveness in oxygenation rather than other devices of oxygen supply. An experimental study was performed to evaluate its efficacy using dogs with respiratory impairment, which were designed by removal of 6 ribs of 5 cm in each from the left thoracic wall and bilateral division of phrenic nerves. The animals were maintained under the condition of spontaneous respiration with air-insufflation through the PITC. The following results were obtained. End-expiratory pressure (0.22 cm H2(0)/1 min) increased. Functional reserve capacity increased. Alveolar ventilation increased. Dead space to tidal volume ratio decreased. PaO2 and PaCO2 improved to the normal range. The immediate postoperative use of this method has been found most satisfactory in respiratory care and elimination of postoperative pulmonary complications.
研究了一种经皮气管内导管（PITC）方法用于术后呼吸护理和预防术后肺部并发症。通过导管以每分钟2 - 4升的速度持续吹入氧气。在20例肺部风险较高的患者中取得了成功结果，这些患者年龄较大、接受大手术且术前存在肺功能不全，结果显示该方法在氧合方面比其他供氧设备更有效。进行了一项实验研究，使用呼吸功能受损的犬来评估其疗效，方法是从左胸壁每侧切除6根5厘米长的肋骨并双侧切断膈神经。动物通过PITC在空气吹入的情况下维持自主呼吸状态。获得了以下结果：呼气末压力（0.22厘米水柱/1分钟）增加；功能储备容量增加；肺泡通气增加；死腔与潮气量之比降低；动脉血氧分压（PaO2）和动脉血二氧化碳分压（PaCO2）改善至正常范围。已发现术后立即使用该方法在呼吸护理和消除术后肺部并发症方面最为令人满意。
