帕瑞昔布钠不同给药时机对THA患者超前镇痛的效果分析

目的 探讨帕瑞昔布钠(PS)不同给药时机对全髋关节置换(THA)患者超前镇痛的临床效果.方法 前瞻性纳入接受THA患者60例,将其分为3组:A组术前3d开始静脉注射PS(40 mg/d),直至术前当天;B组手术切皮前30 min静脉注射PS 40 mg;C组术前3d开始与A组相同时间点静脉注射生理盐水.采用视觉模拟评分法(VAS)评价患者术后6、24、48、72 h静息疼痛;记录患者术后自控镇痛泵(PCIA)的使用时间和总剂量;观察患者术后首次独立下地时间.结果 术后各时间点VAS评分A、B组均明显低于C组(P＜0.05),A组术后6、24 h的VAS评分又明显低于B组(P＜0.05).A、B、C组PCIA的使用时间分别为(25.05±10.32)、(36.75±13.91)、(50.40±15.17)h,两两比较差异有统计学意义(P＜0.05);PCIA中有效镇痛药物舒芬太尼总使用剂量A、B、C组分别为(29.25±4.58)、(34.50±5.09)、(62.65±10.52)μg,A、B组使用剂量明显低于C组(P＜0.05).A、B、C组首次独立下地时间分别为(2.75±0.81)、(3.05±1.08)、(4.10±0.92)d,A、B组相比C组下地时间更早(P＜0.05).结论 术前3d连续使用PS则可提高THA患者镇痛效果,有利于功能康复和提高患者满意度.

Preemptive analgesic effect of administration timing of parecoxib sodium in patients with total hip arthroplasty

Objective To investigate the clinical preemptive analgesic efficacy of parecoxib sodium(PS) at different administration timing in the patients with total hip arthroplasty(THA).Methods Sixty patients receiving THA were prospectively enrolled and randomized into three groups.The group A started to be intravenously injected by PS 40mg/d on preoperative 3 d until operation day;the group B was intravenously injected by parecoxib sodium 40mg at preoperative 30 min;the group C began to be intravenously injected by the same dosage of normal saline at the same time point as the group A.The rest pain was assessed by using the visual analog scale(VAS) at postoperative 6,24,48,72 h.The duration of patient-controlled intravenous analgesia(PCIA) and total dosage were recorded.The first time unaided ambulation time was observed.Results The VAS scores at various postoperative time points in the group A and B were significantly lower than those in the group C(P＜0.05),the VAS scores at postoperative 6,24 h in the group A were remarkably lower than those in the group B.The PCIA duration in the group A,B and C were 25.05±10.32),(36.75± 13.91),(50.40 ± 15.17)h,respectively,the pair-wise comparison of the group A,B and C showed statistical difference(P＜0.05).The total dosages of PCIA drug in the group A,B and C were(29.25 ± 4.58),(34.50 ± 5.09),(62.65 ±10.52)tg,respectively,the dosage in the group A and B was significantly lower than that in the group C(P＜0.05).The first time unaided ambulation time in the group A,B and C were (2.75 ± 0.81),(3.05 ± 1.08),(4.10 ±-0.92)d respectively,which in the group A and B was earlier than that in the group C (P＜0.05).Conclusion Continuously using PS on preoperative 3 d can increase the analgesic effect in THA patients and is conducive to the functional rehabilitation and increase the patient satisfaction.
