Effects of dexmedetomidine + propofol intervention during general anesthesia induction on endotracheal intubation

摘要

Objective: To investigate the effects of dexmedetomidine + propofol intervention during general anesthesia induction on endotracheal intubation. Methods: A total of 218 patients receiving tracheal intubation general anesthesia in the hospital between January 2017 and December 2017 were divided into the control group (n=109) and the dexmedetomidine group (n=109) by random number table method. Control group underwent routine propofol anesthesia induction and dexmedetomidine group underwent dexmedetomidine anesthesia induction on the basis of propofol. The differences in the severity of inflammatory response and stress response were compared between the two groups of patients after general anesthesia induction (T0), 1 min after endotracheal intubation (T1), 5 min after endotracheal intubation (T2) and 10 min after endotracheal intubation (T3). Results: At T0, there was no statistically significant difference in serum levels of inflammatory factors and stress hormones between the two groups. At T1, T2 and T3, serum inflammatory factors CRP, IL-1, IL-6, IL-8 and TNF-α levels of dexmedetomidine group were lower than those of control group; serum stress hormones ACTH, Cor, NE, AngⅠ and AngⅡ levels were lower than those of control group. Conclusion: Dexmedetomidine + propofol general anesthesia induction can effectively reduce the inflammatory stress response caused by endotracheal intubation.
