Optimal Sevoflurane Concentration for Intubation in Combination of Clincal Remifentanil Doses
Summary
Intubation is a procedure that requires well relaxed muscles while general anesthesia is performed. In order to get adequate muscle relaxation, remifentanil, sevoflurane or both agents in combination have been reported as they can provide adequate conditions for laryngoscopy and tracheal intubation without using muscle relaxants. However, there were no previous studies to find the effective dose of sevoflurane in combination with different bolus doses of remifentanil to obtain adequate endotracheal intubation conditions without using muscle relaxants. The aim of this study is to investigate the change in the minimum sevoflurane alveolar concentration which produces an adequate endotracheal intubation condition when sevoflurane is combined with different bolus doses of remifentanil used in clinical practice.
