摘要
目的改进传统的敷料包堆加压皮片固定法。方法在动物实验和临床应用的基础上,改用弹力网和透明气囊替代皮片传统的固定方法。结果临床应用46例获得满意效果。气囊内压力为45~50mmHg,维持压力在30mmHg(X±S=32.45±1.87mmHg)以上。皮片成活率达97.8%,优良率达91.3%,与同期所行54例传统包堆法相比较,在皮片成活率和成活质量方面具有显著性差异(χ2=8.86>χ20.05=7.815,P<0.05)。结论本法优于传统的包堆法,具有科学。
Objective To reform the traditional tie over dressing and make it more scientific and practical. Methods On the basis of animal experiment and clinical application,the former fixed appendix and dressing were replaced with elastic net and transparent gasbag. Results The method has been successfully applied for skin grafting in 46 cases with satisfied results. The pressure in the gasbag is 45 to 50 mmHg, maintaining over 30 mmHg (±S==32.45±1.87 mmHg). The rates of survival and good in grafting are 97.8 % and 91.3 % respectively, which are statistically significant in comparison with traditional method in 54 cases inthe corresponding period (χ 2=8.86>χ 2 0.05 =7.815,P<0.05). Conclusion This method as a new tie over dressing in free skin grafting is more scientific, practical and convenient than the traditional one.
