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 continuous inflation protocol regarding pain as the criterion of over-inflation,the full-load expansion technique,was introduced. It is carried out by restricting persistently the pressure 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 pressure. 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 regions ,total volumes of infusion,areas of the overlying skin and the patient susceptibilities .
