Lubrication is an important factor for passage of a suction catheter through a tracheal tube. This study was carried out to evaluate the effects of lubricants on resistance against removal of a suction catheter from a tracheal tube in an experimental setting.
A tracheal tube (I.D. of 7.5mm) was inserted into a mannequin, and the resistance against removal of a suction catheter from the tube was measured.
Lubrication was improved by using a lubricant (lidocaine jelly or KY jelly), but there was no difference between the effects of the two lubricants. The use of water as lubricant markedly decreased lubrication. Differences in lubrication depending on the type of tracheal tube used, probably due to differences in coating, were also found.
The use of water as a lubricant is not recommended for tracheal suction.
润滑是吸引导管通过气管导管的一个重要因素。本研究旨在评估在实验环境中润滑剂对从气管导管移除吸引导管时阻力的影响。
将一根内径为7.5毫米的气管导管插入人体模型中，并测量从该导管移除吸引导管时的阻力。
使用润滑剂（利多卡因凝胶或KY胶）可改善润滑，但两种润滑剂的效果之间没有差异。用水作为润滑剂会显著降低润滑效果。还发现，根据所使用气管导管的类型不同，润滑效果存在差异，这可能是由于涂层不同所致。
不建议将水用作气管吸引的润滑剂。
