In this study in 90 rats the measured rate of healing, pO2 in sites of postoperative scar and histological specimen of identical excisional wounds produced by CO2-laser, scalpel and combination are compared. The data of healing laser wounds via scalpel ones show slow laser wound healing. We explain, this by inhibition of the inflammation phase due to diminishing macrophages migration into the wound. pO2 data in postoperative scar after laser and scalpel wounds show that laser thermal alteration does not influence CO2 regimen in the scar.
在这项针对90只大鼠的研究中，比较了通过二氧化碳激光、手术刀以及二者联合产生的相同切除伤口的术后瘢痕部位的愈合速率、pO2以及组织学标本。激光伤口与手术刀伤口的愈合数据表明激光伤口愈合缓慢。我们解释，这是由于巨噬细胞向伤口迁移减少导致炎症期受到抑制。激光和手术刀伤口术后瘢痕的pO2数据表明，激光热改变不会影响瘢痕中的二氧化碳状态。
