【 摘 要 】

Objective: This study was designed to compare the effect of dexmedetomidine or ondansetron withhaloperidol, as a control, for the treatment of postoperative delirium in trauma patients.Methodology: A total of 96 adult trauma patients diagnosed with postoperative delirium were randomizedinto three equal groups. Patients were given either 1 μg/kg dexmedetomidine (Dexmed group) or 4 mgondansetron (Ondan group) or 5 mg haloperidol (Halo group), administered twice daily for 3 consecutivedays. Number of delirious patients, patients who needed “rescue haloperidol” and the total amount of“rescue haloperidol” during study period was calculated.Results: At the end of the study, the number of remaining delirious patients was 3, 6, and 2 in Dexmed,Ondan, and Halo groups, respectively, without statistical significance. During the study period, there wasno significant difference in the number of patients who needed “rescue haloperidol” between Dexmedand Halo groups (5 vs. 3; p = 0.7). However, the difference was significantly higher in Ondan groupcompared to Halo group (11 vs. 3; p = 0.03). The mean total “rescue haloperidol” dose was significantlyhigher in Ondan group compared to Halo group (p < 0.001), but there was no difference betweenDexmed and Halo groups (p = 0.07). At the same time of delirium assessment, mean arterial bloodpressure and mean score on Visual Analog Scale were not statistically different between Dexmed orOndan group versus Halo group. No serious adverse events were reported.Conclusion: Dexmedetomidine is a potential alternative treatment for postoperative delirium in traumapatients admitted to ICU.
