Context: Few studies have compared recovery profiles of desflurane and isoflurane for patients undergoing elective supratentorial craniotomy. It is not known if the choice of inhalational agent can affect the duration of transient postoperative neurological deficits in these patients. Aims: To compare the effect of desflurane and isoflurane on time-to-emergence and time-to-recovery of transient postoperative neurological deficits in patients undergoing supratentorial craniotomy. Settings and Design: Prospective, double-blinded, randomized controlled trial at a tertiary care hospital. Methods and Materials: We randomly assigned 60 patients to receive either desflurane or isoflurane during elective supratentorial craniotomy for intra-axial mass lesions. Time-to-emergence and time-to-recovery of transient postoperative neurological deficits were recorded and compared. Statistical Analysis Used: Parametric variables were compared by the Student's t test. Baseline data was compared using Pearson's chi square test, Fisher's exact test and two proportion Z test. Results: There was a 35.7%, 31.4% and 34.5% reduction in median times to eye opening, obeying commands and orientation in the desflurane group (n=27) as compared to the isoflurane group (n=28). Five patients were enrolled but not included for analysis-Twelve patients sustained transient neurological deficits after surgery (desflurane, n=3; isoflurane, n=9). No significant difference in the time-to-recovery of transient postoperative neurological deficits was observed. Conclusions: Desflurane significantly reduced emergence times, and was able to facilitate an early neurological examination for patients. Additional studies are required to establish the impact of inhalational agents on transient postoperative neurological deficits.
