持续无痛快速扩张法及其临床应用

介绍了一种持续无痛快速注水法,即以疼痛开始为超负荷标准的满负荷扩张法。利用自行设计的注水装置,将扩张器内压始终控制在病人的疼痛阈值水平,维持注水速率和皮肤扩张速率的动态平衡。本法注水既非均速也非恒压。13例19个扩张器采用本法注水,5～20天完成。所需时间长短的差别取决于扩张器大小、部位、所扩张皮肤面积的大小及病人的敏感性。我们在详细比较和探讨了各种快速注水方法的基础上,提出了满负荷扩张法的特点和理论依据。

Full-load expansion technique and preliminary clinical application

For accelerating the inflation process of soft tissue expansion, a continu- ous inflation protocol regarding pain as the criterion of over-inflation, the full-load ex- pansion technique, was introduced. It is carried out by restricting persistently the pres- sure in the expander near the pain threshold in a state of dynamic equilibrium between the infusing rate and the skin expansion velocity, with a simple and practical assembled device. This inflation is neither at a uniform infusing rate nor at a constant filling pres- sure. 19 expanders in 13 patients were inflated following this protocol. Their inflations were respectively fulfilled in 5 to 20 days, depending individually on their anatomic re- gions, total volumes of infusion, areas of the overlying skin and the patient susceptibili- ties.
