A separation of the individual latex layers is a known complication of endotracheal armoured tubes manufactured by immersion technique. This can result in herniation into the lumen with obstruction of the tube. Diffusion of nitrous oxide into the inner hernia considerably intensifies the obstruction. This can lead to life-threatening situations. We observed a similar herniation caused by layer separation with subsequent tube obstruction of silicolatex anaesthesia tubes used in paediatric circuit systems. This is caused by manufacturing defects and above all by damage incurred in reprocessing. Therefore it is important to process the tubes carefully. A too-high drying temperature can cause premature layer separation. The tubes should never be processed more than 80 times. Routine examination of the tubes is imperative, especially at the predilection sites for layer separation.
单个乳胶层分离是通过浸渍技术制造的气管铠装管已知的并发症。这可能导致向管腔内疝出并造成管腔阻塞。氧化亚氮扩散到内部疝中会大大加剧阻塞。这可能导致危及生命的情况。我们观察到在儿科回路系统中使用的硅酮乳胶麻醉管因层分离导致类似的疝出，随后出现管腔阻塞。这是由制造缺陷引起的，尤其是再处理过程中造成的损坏。因此，小心处理这些管子很重要。过高的干燥温度会导致过早的层分离。这些管子的处理次数绝不应超过80次。对管子进行常规检查是必不可少的，尤其是在层分离的好发部位。
