Evaluation of Incision-Site Blood Flow Using Laser Speckle Contrast Imaging

Introduction: Maintaining blood flow at the incision site following dermal suturing is one of most important factors affecting postoperative wound healing outcomes. However, this issue has not yet been sufficiently investigated. We aimed to evaluate and compare closure with a combination two techniques/materials in pigs using laser speckle contrast imaging.Materials methods: Pigs (n = 4) were anesthetized, three incisions made upper lower abdomen each 6 per pig). The closed set-back continuous monofilament sutures (incision 1), interrupted 2), barbed 3) 8 for incision). Closure time was measured assessed 20 min after 3 imaging.Results: mean required close (4.36 ± 0.48 min) significantly shorter than that 2 (5.45 0.67 (p 0.019). Statistical analysis changes from baseline corrected points (10, 15, 20) showed reduction tended be smaller 0.579).Conclusions: impairment comparable sutures.
