摘要 目的:研究两种自控镇痛[肌间沟法连续臂丛自控镇痛(PCNA)和连续静脉自控镇痛(PCIA)]对上肢断指再植肢体术后存活率的效果比较。方法:50例急诊断指有再植手术适应证患者,术前按单数、双数分为肌间沟法臂丛自控镇痛(PCNA)A组和静脉自控镇痛(PCIA)B组各25例,分别于术后4 h、12 h、24 h、48 h用彩色多普勒超声监测断指动脉的血流速度,观察断指再植肢体的皮肤颜色、皮肤温度的变化。结果:术后4 h两组各项指标比较,差异无统计学意义(P>0.05),12 h、24 h、48 h时A组均较B组血流速度快(平均相差12.5 cm/s),指脉搏波幅高(平均相差11.40 mm),而且A组均较B组肤色红润、温暖,差异有统计学意义(P<0.05),断指再植肢体存活率提高23%。结论:连续臂丛肌间沟自控镇痛(PCNA)可使再植肢体血管痉挛发生率降低,能有效地维持断指的血液循环,较静脉自控镇痛(PCIA)对断指再植手指的存活率有明显提高。
