Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To determine if the time required to initiate desflurane based minimal flow anaesthesia can be reduced by initial delivery of 6 L/min vis a vis 4 L/min fresh gas flow in terms of achieving the desflurane end tidal concentration of 3.5% and denitrogenation of the breathing circuitTimepoint: When the End tidal concentration of desflurane achieved becomes 3.5% | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. To determine the fall in circuit anaesthetic gas concentration after initiation of minimal flow anaesthesia with the use of the two flows 2. to determine the desflurane consumption in the two groups during the period of studyTimepoint: Outcomes will be measured 15 min after initiation of desflurane and nitrous oxide delivery in breathing gases(the duration of study period is 15 mins after which study is going to be terminated) | — |
