Abstract:
Objective To investigate the effect of dexmedetomidine on tracheal intubation in patients with ICU.Methods A total of 76 severe cases of patients treated in ICU of Kunming General Hospital of Chinese PLA from January 2015 to January 2016 were selected as the subjects,randomly divided into control and observation groups,38 cases in each group.The two groups underwent radial artery puncture before the trachea intubation,and the venous passage was established.The observation group received iv infusion of dexmedetomidine hydrochloride (0.5 g/kg) for 10 min,and the control group received iv injection of normal saline.Then the two groups were given iv infusion of appropriate atracurium and propofol.The anesthesia dosages of two groups were observed;The levels of angiosthenia (MAP),heart rate (HR) and plasma corticosterone were detected before intubation (T1),after intubation (T2),3 min after intubation (T3) and 5 min after intubation (T4) in two groups.Results Propofol and CIS atracurium anesthesia dose of the two groups had no significant difference.The levels of MAP,HR and plasma corticosterone in observation group were significantly lower than those in the control group at T4 and T3 time (P ＜ 0.05).Conclusion Application of dexmedetomidine anesthesia could reduce the stress response in patients with endotracheal intubation in ICU and maintain stable hemodynamics and plasma corticosterone.
