Recovery from desflurane and sevoflurane anaesthesia after prolonged surgery - A comparative study using Index of Consciousness (IoC) monitoring

Abstract

Background: The present study compared the recovery from desflurane and sevoflurane anaesthesia in patients after prolonged surgery using Index of Consciousness (IoC) monitoring scale. Materials and Methods: A total of 50 patients between 18 to 60 years of age, scheduled to undergo prolonged surgeries (lasting for more than 120 minutes) were included in this study and randomly divided in two groups (Group A: Desflurane; Group B: Sevoflurane) of 25 patients each. Results: The patients who received Desflurane had better recovery characteristics than Sevoflurane. Results showed that for attaining value of IoC-95, mean time required by patients of group A was 1.82 (± 0.50) minutes as compared to 5.36 (± 0.95) minutes by group B. Similarly for attaining value of IoC-99 (i.e. state of complete consciousness), mean time required by patients of group A was 11.04 (± 1.62) minutes as compared to 22.84 (± 4.85) minutes by group B. The results were significantly different (p< 0.05) for both the values of IoC. Conclusion: The present study concludes that inhalation based desflurane anaesthesia has a faster recovery than sevoflurane anaesthesia in prolonged surgeries, when both are guided by IoC monitoring.
