The authors present their experience with correct placement of an endotracheal tube. Thirty children were intubated for different indications following the same method. The correct position of the tube was confirmed by chest films. The method included: 1. Tracheal tube introduction by direct laryngoscopy. 2. Deliberate tube displacement to the main right bronchus. 3. Auscultatory carina detection while giving positive pressure ventilation with ambu, when the respiratory murmur appears in the left hemithorax. 4. Tube withdrawal a distance equal to the patient's little finger length, leaving off the tracheal tube tip at an appropriate distance from the carina. The placement was found correct in 29 cases.
作者介绍了他们在正确放置气管导管方面的经验。30名儿童因不同适应证采用相同方法进行插管。通过胸部X线片确认导管位置正确。该方法包括：1. 通过直接喉镜插入气管导管。2. 故意将导管移位至右主支气管。3. 使用复苏球囊进行正压通气时，通过听诊确定气管隆突位置，当左侧胸廓出现呼吸音时。4. 将导管拔出相当于患者小指长度的距离，使气管导管尖端与隆突保持适当距离。结果发现29例放置正确。
