Low Flow Anaesthesia, is There a Difference Between 2 Modern Anaesthetic Machines Using Different Gas Reservoir
- Conditions
- General Anaesthesia
- Registration Number
- NCT02013869
- Lead Sponsor
- Jan Jakobsson
- Brief Summary
To study the Flow-I breathing circle during low flow general anaesthesia, whether this non-below system has advantages reduced time to reach Et 1MAC (minimal alveolar concentration) and lower consumption of inhaled agent
- Detailed Description
Assessing whether there are clinical differences in anaesthetic performance between standard anaesthesia workstation including a below and the new Flow-I device without a below

- PARALLEL
- Primary Outcome Measures
Name Time Method Time to reach 1.5 MAC (minimal alveolar concentration) Et 1 hour The time needed, seconds, to increase the end tidal desflurane concentration during wash-in from a 1 MAC to a 1.5 MAC with a constant fresh gas flow of 1 L/min and the vaporiser set a 3 MAC ( minimal alveolar concentration) (18%) will be compared between the two study groups
- Secondary Outcome Measures
Name Time Method amount of inhaled agent consumed ml/min 5 hours The vaporiser will be weighed before and after each case and the amount of vapor, desflurane, consumed during the anaesthesia will be calculated Gr/min.
Postoperative Quality of Recovery 72 hours Quality of recovery will be followed during the first 72 hours after anaesthesia
