Sevoflurane and airway anaesthesia.

摘要

I read with interest the article from Kim et al1 regarding the optimal dose of propofol during airway procedures under sevoflurane anaesthesia. Sevoflurane is an excellent agent for inhalational induction. However, I feel the agent is not ideal for airway manipulation or for that matter many procedures under spontaneous breathing. Despite the rapid onset of unconsciousness with sevoflurane, I have found that onset of 'surgical anaesthesia' is quite delayed and at times difficult to achieve. Simply increasing inhaled concentrations often results in apnoea rather than the adequate depth required for surgical intervention or airway manipulation.
