Low Flow Anaesthesia, is There a Difference Between 2 Modern Anaesthetic Machines Using Different Gas Reservoir

Not Applicable
Terminated
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

Primary Outcome Measures
NameTimeMethod
Time to reach 1.5 MAC (minimal alveolar concentration) Et1 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
NameTimeMethod
amount of inhaled agent consumed ml/min5 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 Recovery72 hours

Quality of recovery will be followed during the first 72 hours after anaesthesia
