Eighty attempts at placing suction catheters in the left main bronchus were analysed by studying chest radiographs. When angled catheters were used via a tracheostomy tube the success rate was 75%; the rate fell to 15% when straight tubes were used through an orotracheal tube. Assessment and control of the tube length was found to be important to avoid kinking and subsequent obstruction of the catheters.
通过研究胸部X光片，对80次将吸引导管置入左主支气管的尝试进行了分析。当通过气管造口管使用弯头导管时，成功率为75%；当通过口气管插管使用直管时，成功率降至15%。发现评估和控制导管长度对于避免导管扭结和随后的阻塞很重要。
