ABSTRACT
Objective:To observe the effect of dexmedetomidine used in ophthalmic surgery anesthesia on the recovery quality in children. Methods:Totally 126 children with ophthalmic surgery were randomly divided into the control group and the observation group with the same induction program. The control group was given propofol with target controlled infusion during the operation, while the observation group was given dexmedetomidine 0. 6μg·kg-1 before the induction, and infused up in 10min, propofol with target controlled infusion was used during the operation, and stopped infusion 10min before the end of the operation. The cough number and degree, the occurrence of agitation and extubation time of the two groups were observed and compared during the anesthesia recovery period. Results:The cough incidence and agitation incidence was 36. 51% and 4. 76% in the observation group, respectively, which were significantly lower than those in the control group (74. 60% and 33. 33%, P0. 05). Conclusion:Dexmedetomidine used in ophthalmic surgery anesthesia of children can effectively control cough frequency and degree during the recovery period and reduce the agitation to improve the quality of clinical anesthesia recovery.
