Objective: To compare the analgesic effects of lidocaine aerosol and lidocaine injection combined with diclofenac potassium suppository in children undergoing circumcision. Methods: A total of 260 children undergoing circumcision in Baoji Maternal and Child Health Care Center were divided into the study group and control group via the random table method

with 130 cases in each group. The control group was given lidocaine local injection anesthesia with diclofenac potassium suppository

while the study group received lidocaine aerosol with diclofenac potassium suppository. The anesthetic effects of two groups were compared. Results: Compared with the control group

the preoperative coordination of the study group was higher

and the operation time and onset time of anesthesia were shorter (P<0. 05). The FLACC scores of pain degree at the beginning of surgery (T0)

after circumcision (T1) and at the end of surgery (T2) in the study group were lower than those in the control group (P<0. 05). The total satisfaction rate of anesthesia in the study group was higher than that of the control group (P<0. 05). Conclusion: Lidocaine aerosol combined with diclofenac potassium suppository has better analgesic effect on circumcision

with lower postoperative complication rate and higher overall satisfaction rate

which is worthy of clinical promotion and application.
