Abstract:
Objective To evaluate the treatment effect of combination of dexmedetomidine and droperidol on emergence agitation during general anesthesia recovery period in the elderly undergoing thoracotomy. Methods Sixty patients with severe emergence agitation during general anesthesia recovery period undergoing thoracotomy for esophageal cancer or pulmonary lobectomy, aged 66-75 years, falling into ASA physical status Ⅱ or Ⅲ, were divided into three groups, 20 patients in each according to table of random number: group droperidol (group F) and group dexmedetomidine (group D) and group dexmedetomidine combining droperidol (group DF). In group F, 0.06 mg/kg droperidol was administrated via central vein. In group D, 1 μg/kg dexmedetomidine was pumped via central vein in 10 min, followed by continuous infusion of dexmedetomidine in 0.2 μg·kg-1·h-1 for 1 h. While in group DF, 0.03 mg/kg droperidol was administrated via central vein and 0.5 μg/kg dexmedetomidine was pumped via central vein in 10 min, then followed by continuous infusion of dexmedetomidine in 0.2 μg·kg-1·h-1 for 1 h. The agitation scores and the Ramsay scores were collected after the beginning of anti-agitation. Arterial blood partial pressure of carbon dioxide was tested. Postoperative complications including nausea and vomiting were recorded. Results Compared with group D, the agitation scores at 5, 10, 15 and 20 min in group DF were lower (P ＜ 0.05). Comparing with group F, the agitation scores at 60, 90 and 120 min in group DF were lower (P ＜ 0.05). The incidence of over-sedation in group DF and in group D was less than that in group F (P ＜ 0.05). PaCO2 was unaltered in all the groups after treatment. The incidence of nausea, vomiting, bradycardia, hypertension, hypotension and respiration depression and long QT interval between the groups were comparable. Conclusion Combination of dexmedetomidine and droperidol is effective and safe in the treatment of agitation during sevoflurane general anesthesia recovery period in the elderly undergoing thoracotomy.
