ABSTRACT

Conclusion:

As a result in cases over 60 years old, desfluran can be preferred due to rapid recovery and also it would be safer to follow the patients in recovery period, with BIS monitorization, in recovery unit.

Results:

We found SEOT as 9.25±0.35/min and 7.45±0.35/min, SRT as 9.15±0.34/min and 7.35± 0.31/min, ET as 7.95±0.30/min and 6.00±1.49/min, CT as 11.40±0.48/min and 9.65±0.48/min, PACU discharge time as 48.75±1.19/min and 38.10±0.83/min, in Group I and II respectively with values shorter in desfluran group (p<0.05). There was no statistically significant difference in BIS values.

Material and Methods:

40 cases over 60 years old who were planned to perform lumbar disc surgery under general anesthesia in group ASA I-II were included in the study and subjects were randomly divided into two groups. In both groups, anesthesia was inducted with intravenous (IV) propofol per 1.5-2 mg/kg. In the first group (n=20) anesthesia was maintained with the mixture of sevofluran (0.6-1.75%), 50% air and 50% O2, and in the second group (n=20), anesthesia was maintained with desfluran (2-6%), 50% air and 50% O2 mixture. Following the end of anesthesia spontaneous eye open time (SEOT), spontaneous respiration time (SRT), intubation time (ET), consciousness time (CT), discharge time from the postanesthesia care unit ( PACU discharge) and BIS values in this period were recorded.

Objective:

Our study was performed to the patients over 60 years old, who take anaesthesia more than two hours, to compare the recovery durations of desfluran and sevofluran and the bispectral index values (BIS) within this period.
