临床观察发现,断肢后局部动脉灌注利多卡因能扩张微血管,提高断肢再植存活率。断肢地鼠颊囊微血管的活体测量结果证明动脉局部灌注或局部滴注利多卡因后微动脉明显扩张。本文在此基础上初步探讨利多卡因
Clinical observations found that local arterial perfusion of lidocaine after amputation can expand the microvascular and improve the survival rate of replantation limbs. In vivo measurements of the hamstring cheek pouch capillaries demonstrated that there was a significant expansion of the arterioles after local arterial perfusion or local drip of lidocaine. This article based on this preliminary study of lidocaine
