超声引导罗哌卡因复合地塞米松髂筋膜间隙阻滞应用于全膝关节置换术围术期的镇痛效果

目的 探讨超声引导罗哌卡因复合地塞米松髂筋膜间隙阻滞(FICB)在全膝关节置换术(TKA)围术期的镇痛效果.方法 将行TKA治疗的48例患者根据随机数字表法分为观察组和对照组,每组24例.两组术前0.5 h均在超声引导下行FICB,观察组注入0.375％罗哌卡因30 ml+地塞米松10 mg,对照组注入0.375％罗哌...

Analgesic effect of ultrasound-guided ropivacaine combined with dexamethasone fascia iliaca compartment block for perioperative period of total knee arthroplasty

Objective To investigate the analgesic effect of ultrasound-guided ropivacaine combined with dexamethasone fascia iliac compartment block(FICB)during perioperative period of total knee arthroplasty(TKA).Methods The 48 patients undergone TKA were randomly divided into observation group and control group according to the number table method,24 patients in each group.The two groups patients were performed with FICB under the ultrasound-guided at 0.5 h preoperation;30 ml of 0.375%ropivacacine with 10 mg of dexamethasone were used in the observation group,and 30 ml of 0.375%ropivacaine was used in the control group,respectively.Perioperative analgesic effect,opioid dosage within 48 h after operation,incidence rate of nausea and vomiting,and FICB related complications were observed in the two groups.Results VAS of the resting and exercise at 12,24,36 h after drug injection and the times of analgesia pump pressure in the observation group were both lower(less)than those of the control group(P<0.05);there was no differences of VAS of the resting and exercise at 3,6,8,48 h after drug injection,and incidence rate of nausea and vomiting between the two groups(P>0.05).No FICB related complications were found in either group.Conclusions Compared with ropivacaine alone,ultrasound-guided ropivacaine combined with dexamethasone FICB can prolong postoperative analgesia time and reduce opioid dose at 48 h postoperation.
