| Objective To investigate the influence of dexmedetomidine on the caudal block with ropivacaine in children.Methods60patients suffering from indirect inguinal hernia or hydrocele of tunica vaginalis and aged1-6years were enrolled in our study. They were divided into two groups randomly to receive0.25%ropivacaine lmg/kg (group R) and0.25%ropivacaine lmg/kg and dexmedetomidine1μg/kg (group RD). The intra-operative heart rate(HR), respiratory rate(RR), tidal volume(TV), blood pressure(BP) and SpO2were normally monitored. The time of the onset of caudal block, the recovery of consciousness and the administration of analgesics were recorded. We select the Ramsay score to estimate the recovery from anesthesia and post-operative agitation and the FLACC Pain Assessment Tool to assess post-operative pain.Results The age, weight, duration of operation and the onset of caudal block were comparable (p>0.05). Group RD displayed The recovery time were increased, post-operative agitation and the overall dose of analgesics of group RD were reduced in comparison with group R, while group RD displayed a markedly prolonged antalgic duration(p<0.05).Conclusions Dexmedetomidine (1μg/kg) can enhance the effect of ropivacaine for the caudal block in children. |
