• W2945864083 abstract "BACKGROUND Perioperative anxiety is common in pediatric patients undergoing surgery. AIMS The aim of this study was to determine whether an infusion of dexmedetomidine prior to hernia repair in children provides better postoperative anxiety outcomes that a preoperative infusion of midazolam. METHODS Ninety 6-11-year-old children, who were scheduled to undergo elective hernia repair, were enrolled for this double-blind, randomized controlled trial. Group D (n = 45) received an intravenous infusion of dexmedetomidine (0.5 μg/kg) and Group M (n = 45) received an intravenous infusion of midazolam (0.08 mg/kg) in 20 mL of normal saline for 10 minutes before the induction of anesthesia. Pre- and postoperative scores on the modified Yale Preoperative Anxiety Scale were the main outcomes. Secondary outcomes included systolic blood pressure, diastolic blood pressure, heart rate, and postoperative pain measured on a visual analogue scale and patient satisfaction using a numerical rating scale. RESULTS Postoperative anxiety in Group D was significantly lower than preoperative anxiety (2 hours postoperatively mean difference [95% CI]: 2.83 [0.87-4.79], P = 0.036, 4 hours postoperatively mean difference [95% CI]: 3.29 [1.39-5.20], P = 0.005). Preoperative and postoperative anxiety in Group M was similar. Anxiety scores in Group D were also significantly lower than anxiety in Group M 2 hours (mean difference [95% CI]: 1.89 [0.52-3.26], P = 0.01) and 4 hours (mean difference [95% CI]: 3.32 [1.98-4.66], P < 0.001) postoperatively. Systolic blood pressure, diastolic blood pressure and heart rate were lower in Group D than in Group M after administration of sedative drugs until children left PACU (SBP mean difference [95% CI]: 13.87 [10.30-17.43], P < 0.001, DBP mean difference [95% CI]: 5.96[3.80-8.11], P < 0.001, HR mean difference [95% CI]: 10.36 [7.58-13.13], P < 0.001). Pain was also significantly lower in Group D than in Group M at 2 hours (median difference [95% CI]: 1 [0.26-1.34], P = 0.004), 4 hours (median difference [95% CI]: 1 [0.31-1.02], P = 0.003), and 1 day (median difference [95% CI]: 0 [0.22-0.76], P = 0.003) postoperatively. Patient satisfaction scores were significantly higher in Group D than in Group M 1 day (median difference [95% CI]: 0 [-0.83 to -0.24], P = 0.006) and somewhat higher 1 week (median difference [95% CI]: 0 [-0.67 to -0.04], P = 0.06) postoperatively. CONCLUSION Compared with midazolam, a single preoperative intravenous dose of dexmedetomidine appears to provide better postoperative anxiolytic effects for children undergoing same-day surgery." @default.
