文摘目的 探讨收肌管阻滞(ACB)联合静脉自控镇痛(PCIA)对行全膝关节置换术患者术后抑郁状态的影响。方法选择行全膝关节置换术的患者随机分为ACB联合PCIA组(A组)40例和PCIA组(B组)40例。B组术后给予PCIA镇痛方法,A组在B组基础上术前联合ACB镇痛。记录术后2 h(T_(1))、6 h(T_(2))、12 h(T_(3))、24 h(T_(4))、72 h(T_(5))静息和运动VAS评分,术后补救镇痛药物使用情况,恶心呕吐发生情况,术前、术后1 d、术后3 d医院焦虑抑郁量表(HADS)评分。结果A组患者T1~T4时静息和运动VAS评分明显低于B组(P<0.05);A组患者术后补救镇痛药物使用量明显减少(P<0.05),恶心呕吐发生率明显降低(P<0.05);A组患者术后1 d HADS评分及术后出现显著的抑郁症状(HADS-D≥8)的患者比例明显低于B组(P<0.05);术后1 d HADS评分与T1~T4时静息和运动VAS评分呈明显正相关(P<0.05);术后3 d HADS评分与T_(1)~T_(3)时静息和运动VAS评分呈明显正相关(P<0.05)。结论ACB联合PCIA相比单纯PCIA在全膝关节置换术后镇痛效果更加显著,并可减少术后抑郁的发生,促进患者快速康复。
