吸烟对再植成活后断指远期血流灌注的影响

目的观察吸烟对再植成活伤指血流灌注的长期和即刻影响。方法2004-12～2007-01应用脉冲超声多普勒速度仪(PUDVP)和电子温度计,对21例(28指)恢复吸烟男性再植成活中节手指的长期和即刻血流灌注进行观察,并与同期术后戒烟患者伤指的血流灌注进行比较。结果断指再植术后吸烟组指动脉平均血流最大速度与指动脉血流量低于术后戒烟组(P<0.05),手指末节温度吸烟组与戒烟组差别不显著(P>0.05)。试验吸烟后再植断指指动脉最大血流速度迅速下降,1、3.5、15、30min分别降低11.1%、60.0%、20.9%、8.6%;最大血流量同时分别下降9.2%、33.2%、12.3%、9.1%。吸烟后手指末节温度缓慢下降,5min后达最低值,然后逐渐回升,30min后恢复达试验前90%。结论吸烟不会导致再植成活断指失活,但明显降低伤指血流灌注,建议患者尽可能减少吸烟、甚至戒烟。

The impact of smoking on ling-term blood flow perfusion of surviving digits following replantation

Objective To investigate the long-term and instant impact of smoking on blood flow perfusion of surviving digits after replantation course. Method From December 2004 to January 2007, the long-term and instant blood flow perfusion of 28 midplate digits of 21 male cases who recovered smoking after surviving replantation course were observed by pulsed ultrasonic doppler velocimetry(PUDVP) and electronic thermomete. The measurement results was analyzed and compared with digit blood perfusion of patients who gav...
