目的评估背部成对皮瓣扩张器埋置在活体小型猪实验动物模型中的可行性及安全性。方法共选用6只10～12kg重的广西巴马小型猪,每头猪分别在背部两侧共设计6个5cm×7cm100mL埋扩张器的手术区域,背部脊柱左侧术区埋置扩张器,脊柱右侧术区作为对照组。结果实验组扩张皮瓣与对照组皮瓣的皮瓣存活率相比,有显著性差异(P<0.05)。但扩张皮瓣之间的存活率相比,没有显著性差异(P>0.05)。结论背部成对皮瓣埋置扩张器在小型猪模型中皮瓣存活率稳定,减少了个体差异,是用于扩张皮瓣研究的合适模型。
Objective To assess the feasibility and safety of dorsal paired flap dilators embedded in a live miniature pig experimental animal model. Methods A total of 6 Guangxi Bama miniature pigs weighing 10 ~ 12kg were selected. Six pigs with a 5-mm × 7cm, 100-mL burr were designed on each side of the back. The dorsal spine Right surgery as a control group. Results The flap survival rate in the experimental group was significantly different from that in the control group (P <0.05). However, there was no significant difference in the survival rate between the expanded flaps (P> 0.05). Conclusion The dorsal paired flaps embedded dilator is a suitable model for the study of dilatation flaps because of its stable flap survival rate and individual differences in miniature pig model.
