Pulmonary collapse after intubation is common, and it is caused by a variety of factors.
A 21-year-old man presented at our operation room to undergo an appendectomy. Except for a history of cigarette smoking, his history was negative. Anesthesia was induced with 100% oxygen and sevoflurane, remifentanil infusion, and propofol. Neuromuscular block was obtained with rocuronium. The tip and cuff of a tracheal tube were lubricated with a topical metered-dose of 8% Lidocaine pump spray. After intubation, SPO2 suddenly decreased. The chest x-ray revealed right upper lobe atelectasis. Fiber optic bronchoscopy showed that a large amount of yellow sticky mucus had been secreted into the right main bronchus.
In Japan, 8% Lidocaine pump spray contains menthol and ethanol as additives. These additives, particularly menthol, might have led to excessive mucus production, although we did not analyze the mucus secretion.
插管后肺萎陷很常见，且由多种因素引起。
一名21岁男性到我们手术室接受阑尾切除术。除吸烟史外，其既往史无异常。采用100%氧气、七氟醚、瑞芬太尼输注及丙泊酚诱导麻醉。使用罗库溴铵实现神经肌肉阻滞。气管导管的尖端和套囊用局部定量的8%利多卡因泵喷雾润滑。插管后，血氧饱和度（SPO2）突然下降。胸部X线显示右上叶肺不张。纤维支气管镜检查显示右主支气管内分泌了大量黄色粘性黏液。
在日本，8%利多卡因泵喷雾含有薄荷醇和乙醇作为添加剂。尽管我们未对黏液分泌进行分析，但这些添加剂，尤其是薄荷醇，可能导致了黏液分泌过多。
