Key result
Dexmedetomidine significantly improved anesthetic stability by better maintaining bispectral index scores and hemodynamic parameters during the intraoperative period compared to propofol and isoflurane (p<0.05).

Does dexmedetomidine improve anesthetic stability (BIS and hemodynamic indices) compared to propofol and isoflurane in patients undergoing elective surgery under general anesthesia?
p-value: p=<0.05
Dexmedetomidine provides superior intraoperative hemodynamic stability and depth of anesthesia compared to propofol and isoflurane in patients undergoing elective surgery.

, and Group I with isoflurane at 1 minimum alveolar concentration (MAC) for 10 minutes and then maintained between 0.5 MAC and 1.5 MAC until the duration of surgery. To maintain the surgical plane of anesthesia, the BIS score was monitored between 40 and 65. The quantitative variables were expressed as mean±SD and compared between groups using Student's unpaired t-test. Data analysis was done using SPSS Statistics for Windows version 20.0 (IBM Corp., Armonk, NY, USA). A p-value of <0.05 was considered statistically significant. Results During intergroup comparison among study drugs, the mean BIS values were statistically significant among the groups (p<0.05). Hemodynamic indices were significantly better maintained in the dexmedetomidine group as compared to the isoflurane and propofol groups throughout the intraoperative period (p<0.05). Conclusion Dexmedetomidine is better than propofol and isoflurane in maintaining the BIS score and hemodynamic parameters during the intraoperative period.

Kumar et al. (2022) conducted an RCT in Elective surgical procedures requiring general anesthesia (n=60). Dexmedetomidine vs. Propofol and Isoflurane was evaluated on Anesthetic stability assessed by bispectral index (BIS) and hemodynamic indices (heart rate and mean arterial pressure) (p=<0.05). Dexmedetomidine significantly improved anesthetic stability by better maintaining bispectral index scores and hemodynamic parameters during the intraoperative period compared to propofol and isoflurane (p<0.05).
