A rat model was developed to test the watertightness of sutures. In this model it was proved that welding by use of low-voltage coagulation current did not improve on the watertightness obtained with conventional skin suturing. The mean leak pressure after welding was about 4.2 cm H2O, i.e. statistically significantly lower than the mean leak pressure of the conventional suture, which is 14.1 cm H2O. Neither addition of protein solder nor an additional conventional suture improved these results. It is therefore concluded that low-voltage coagulation is unsuitable for welding tissues.
开发了一种大鼠模型来测试缝合线的水密性。在该模型中,已证明使用低压凝固电流进行焊接并不能改善传统皮肤缝合所获得的水密性。焊接后的平均渗漏压力约为4.2 cm H₂O,即统计学上显著低于传统缝合线的平均渗漏压力14.1 cm H₂O。添加蛋白焊料或额外的传统缝合线均未改善这些结果。因此得出结论,低压凝固不适用于组织焊接。
