Abstract:
Objective To investigate the effects of dexmedetomidine on sedation and inflammatory response in patients undergoing brachial plexus anesthesia, to provide a reference for the selection of sedative drugs in forearm traumatic patients undergoing brachial plexus block anesthesia .Methods 80 forearm traumatic patients underwent trauma surgery with brachial plexus nerve block from July 2015 to June 2016 were selected and randomly divided into two groups of dexmedetomidine group (dexmedetomidine group, D group) and normal saline group (control group, C group), each group of 40 cases.The mean arterial pressure (MAP), heart rate (HR) and blood oxygen saturation (SpO2) were recorded before operation (T0), incision (T1), 15 min (T2), 30 min (T3).Interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor-α(TNF-α) were measured at different time points. At the same time, the Ramsay sedation score and the degree of amnesia after operation were measured.Results There were no significant differences in MAP, HR and SpO2 before anesthesia between the two groups.In group D, MAP and HR were significantly lower than those in group C at T1, T2, T3 and T4, the difference was statistically significant (P<0.05).There was no statistical difference in SpO2 between the two groups.The Ramsay sedation score of group D at T1 to T4 was significantly higher than that of group C, the difference was statistically significant (P<0.05).The levels of IL-1β, IL-6 and TNF-αin group D were significantly lower than those in group C at T1 to T4, the difference was statistically significant (P<0.05).Conclusion Dexmedetomidine has good curative effect on forearm traumatic patients with brachial plexus block and less hemodynamics changes , which is beneficial to patients'forgotten of operation and inhibition of inflammatory reaction in forearm traumatic patients.
