    Clinical   effect of constant magnetic field on postoperative wound healing
  【Abstract】  AIM: To investigate the clinical effect of constant magnetic field on postoperative wound healing. METHODS: One hundred and twenty patients (40 cases of caesarean operation, 28 cases of orthopaedics, 20 cases of surgical sutures and 32 cases of appendicitis), according to the kinds of these operations, were randomly divided into 2  groups (n=60). The experimental group was bound up with magnetic adhesive bandages, which were made of 0.2 T constant magnetic flakes. The control group was bound up with bandages free of magnetic flakes. Ten days later, the conditions of postoperative wound healing were observed, and the clinical curative effects were evaluated. RESULTS: Compared with those in the control group, total efficiencies of wound healing in experimental group showed statistically significant differences (96.7% vs 90.0%, P<0.05). No difference was found among the kinds of operation in the experimental group (P>0.05). CONCLUSION: The constant magnetic field can promote the wound healing and has a wide range of clinical application.

  【摘要】 目的: 观察0.2 T恒磁场对术后伤口愈合的影响. 方法: 手术后患者120例(其中妇科剖腹产40例、骨科28例、外伤缝合术20例、阑尾炎手术32例)按手术类型等分为两组: 实验组和对照组. 两组均正常换药,实验组用0.2 T恒磁片制作的敷带包扎治疗,对照组用空白敷带包扎,不曝磁. 10 d后对创伤愈合情况进行观察,并对疗效进行评价. 结果: 实验组有效率为96.7%,对照组有效率为90.0%,组间疗效差异显著(P<0.05). 实验组不同手术种类之间的疗效无差异(P>0.05). 结论: 稳恒磁场能提高术后的伤口愈合速度和质量,临床适用范围较广.

  0引言
  磁场作为一种可施加于人体的外来物理因子,在临床上应用广泛. 近年来,国内外进行了许多关于磁场生物效应的基础和应用研究,随着生物医学工程学的快速发展,该领域的相关研究已成为生物工程学界的研究热点[1]. 但由于磁场生物效应的研究资料大部分是基于动物实验,临床试验资料相对较少,因此磁场临床疗效的合理评价和作用机制仍有待于进一步研究[2]. 我们探讨0.2 T恒磁场对120例患者术后伤口愈合的影响,以期为临床磁疗的广泛应用提供理论依据.
  1材料和方法
  1.1材料敷带和恒磁片由陕西众邦药业科技有限公司提供,粘性敷带由无菌纱布制成(经60Coγ射线灭菌),磁片(1 cm)为钕铁硼稀土材料,经磁强计实测中心磁场强度为0.2 T.
