General anaesthesia with sevoflurane using VIMA technique

Overview

The paper summarizes our first experience with VIMA technique of sevoflurane anaesthesia. 12 patients scheduled for minor surgical, orthopedicor trauma surgery were induced with VIMA – tidal breath induction technique with sevoflurane. During induction, there was observed apnoea in 3patients, excitatory phenomenons in 2 patients and cough (once) during laryngeal mask insertion. The loss of consciousness assessed as a lack ofeye-lash reflex was observed after 95,6±30 secs. The insertion of laryngeal mask was possible after 190,2±66,6 secs after the beginning of sevofluraneadministration. After 42,1±28,5 mins of anaesthesia duration, the recovery was standard with times to laryngeal mask removal 423,1±173 secs,eye-opening 454,5±173 secs and orientation 514±196 sec. VIMA technique is simple and safe technique of general anaesthesia. It is well tolerated bypatients. Anaesthesia is preferentially maintained using low-flow technique.
