Abstract:
Objective To observe the analgesia effects of ropivacaine with sufentanil or dezocine on continuous femoral nerve block (FNB)after total knee arthroplasty (TKA).Methods Sixty un-dergoing selective unilateral TKA patients,received postoperative analgesia with continuous FNB for 48 hours,were randomly divided into three groups according to the drug formulations:0.225% ropiv-acaine (group R),0.1 5% ropivacaine mixed dezocine 10 mg (group D),and 0.1 5% ropivacaine mixed sufentanil 1 μg/kg (group S);the visual analogue scale (VAS)in resting state (RVAS), active functional exercise state (AVAS),passive functional exercise state (PVAS)were recorded at 1,3,7 d after surgery.The other analgesics dosage and the incidence of nausea and vomiting and other complications were recorded.Results Compared with preoperative state,the RVAS scores in three groups were significantly lower at 1,3,7 d after surgery,the PVAS scores were significantly lower at 7 d after surgery (P <0.05).Compared with group R,the RVAS scores were significantly higher ei-ther in groups S or D at the 3 d postoperatively (P <0.05).There were no significantly difference in adverse reaction among three groups.Conclusion Ropivacaine combined with sufentanil or dezocine through continuous FNB can provide a effectual postoperative analgesia in TKA patients without an increase in adverse events.But compared to 0.225% ropivacaine,0.1 5% ropivacaine with sufentanil or dezocine may not keep a longer analgesia duration,this is more obvious observed in dezocine group.
