Continuous expansion using an infusion pump was studied in seven patients. Tissue expanders were attached to outpatients under general anesthesia. After a period of 7 days, the skin expansion was initiated with the patient hospitalized. Saline solution (0.9%, 1-3 ml/h) was infused via a gauge needle connected to the expander valve and to the infusion pump. The expansion speed was determined by clinical parameters, such as pain and the expanded tissue viability, until the desired volume was achieved. The total time required for this procedure was 13-18 days. Based on continuous skin expansion, we attempted to test an alternative shorter procedure. This method was well accepted by doctors and patients, and no complications occurred. Although fibrosis was observed, it was not as pronounced as in the outpatients undergoing the conventional expansion treatment. A principal advantage of the continuous expansion method is the increased safety resulting from more effective clinical control and adequate systemic antibiotic therapy. Coupled with on important reduction the expansion time and allowing a faster return of the patients to their activities.
对7例患者进行了使用输液泵持续扩张的研究。在全身麻醉下将组织扩张器连接到门诊患者身上。7天后，在患者住院期间开始皮肤扩张。通过连接到扩张器阀门和输液泵的规格针头输注生理盐水溶液（0.9%，1 - 3毫升/小时）。根据疼痛和扩张组织活力等临床参数确定扩张速度，直至达到所需体积。该过程所需的总时间为13 - 18天。基于持续皮肤扩张，我们尝试测试一种替代的更短程序。该方法得到了医生和患者的良好接受，且未发生并发症。虽然观察到有纤维化，但不如接受传统扩张治疗的门诊患者明显。持续扩张方法的一个主要优点是通过更有效的临床控制和适当的全身抗生素治疗提高了安全性。同时显著缩短了扩张时间，并使患者能够更快地恢复活动。
