Plastic drapes are used in surgery for a wide range of purposes, but currently marketed drapes often become detached from the wound edge during surgery. The purpose of this study was to determine the appropriate adhesive layer thickness for optimal peel and shear strength and the smallest peeled area to improve surgical drape wound adhesion.
Thirty-two rats were randomly assigned to four groups of different adhesive layer thickness (50, 100, 300 and 800-1000 μm). The rats were anaesthetized, and drapes were applied to the dorsal chest. After incision, the peeled area was visualized by dropping ink in the wound site to measure the peeled area over time.
All drapes peeled off from the wound edge, and the peeled area increased over time. The peeled area decreased in the order of 50 μm > 100 μm > 800-1000 μm > 300 μm.
It is possible to control the peeling of plastic drapes during surgery by limiting the peeled area at the time of cutting. Three-hundred micrometres is the suitable adhesive layer thickness to minimize the peeled area at cutting.
塑料手术巾在手术中有广泛的用途，但目前市场上的手术巾在手术过程中经常从伤口边缘脱落。本研究的目的是确定合适的胶层厚度，以获得最佳的剥离和剪切强度以及最小的剥离面积，从而改善手术巾与伤口的粘连。
32 只大鼠随机分为四组，胶层厚度分别为 50、100、300 和 800-1000μm。大鼠麻醉后，在背部胸部敷上手术巾。切口后，在伤口部位滴入墨水，观察剥离区域，以随时间测量剥离区域。
所有手术巾均从伤口边缘剥离，剥离区域随时间增加而增加。剥离区域的顺序为 50μm>100μm>800-1000μm>300μm。
通过限制切割时的剥离区域，可以控制手术中塑料手术巾的剥离。300μm 是合适的胶层厚度，可以最大限度地减少切割时的剥离区域。
