九岁以下小儿麻醉堠痉挛的发生率为17.4‰,几乎是全部麻醉病人喉痉挛发生率(8.7‰)的两倍。大多数喉痉挛并不一定导致合并症,但却完全有可能形成喉梗阻,误吸胃内容或心脏骤停致死。一、喉痉挛的病理生理麻醉时发生喉痉挛的病理生理机制尚未完全阐明,有可能是由于真声带关闭,导致呼吸道完全性或部分性阻塞。Keating认为喉痉挛真声带或真假声带同时在中线关闭对
The incidence of narcotic spasm in children under the age of nine was 17.4 ‰, almost twice the incidence of laryngospasm in all anesthesia patients (8.7 ‰).
