Comparison of ketamine-propofol vs remifentanyl-propofol induction on laryngeal mask insertion conditions: Which is the ideal induction agent combination? [Ketamin-propofol ve remifentanil-propofol indüksiyonunun laringeal maske yerleştirme: koşullari açisindan karş1laştirilmasi: ideal indüksiyon ajan kombinasyonu hangisi?]

Objective: many intravenous agents have been used for laryngeal mask insertion. to achieve successful laryngeal mask insertion,efficient anesthetic depth and mouth opening is necessary. this study aims to compare ketamine and remifentanyl effects on laryngeal mask insertion conditions. method: after routine and bis monitorisation,patients were divided into two groups by envelope method. one group received 1 meg kg' remifentanil for 30 s and 2 mg kg1 propofol,the other group received l mg kg' ketamine for 30 s and 2 mg kg'1 propofol for induction,and then laryngeal mask was inserted. hemodynamic values,bis values,laryngeal mask insertion scores and insertion time were recorded. results: adding ketamine or remifentanyl to propofol showed similar effects on laiyngeal mask insertion conditions. ketamine showed more stable hemodynamics. while remifentanyl achieved deeper anesthesia,no statistical difference was detected compared to ketamine. according to scheme classification,remifentanyl provided better results. conclusion: ketamine or remifentanyl with propofol are alternative agents for laryngeal mask insertion.
