伤口闭合
Key points
- 温和地处理组织是确保无瘢痕愈合的关键
- 当预计存在创面张力时应采用褥式缝合法
- 单丝缝线不容易引起粘膜炎症,但会降低患者的舒适度
注意事项
伤口闭合可保护手术部位并影响肉芽组织上角化细胞的迁移,从而确保并加速伤口愈合。一些伤口外翻可最大限度提高表皮对合。最常用的缝合类型是方结缝合,即在一个方向打两个结,然后在相反方向打第三个结。通常,间断缝合可比连续缝合提供更高的抗张强度。
方法概述
- 使用反三角缝合针可降低组织拖出缝线的风险
- 垂直穿透粘膜,即与粘膜呈 90° 角
- 在出口处用无齿镊固定缝针,然后将其从持针钳松开
- 温和的处理可避免组织缺血
- 缝线应在 7-14 天后拆除,具体取决于伤口长度、张力和患者的年龄
- 如果在褥式缝合时具有很高的粘膜张力,则宜延期拆除缝线
- 女性的口腔粘膜愈合时间长于男性
- 埋入的可吸收缝线可以留在原处
缝合和粘合材料
- 肠线不应再继续使用,目前已被性能更好的合成材料所代替
- 聚乙醇酸 (PGA) 缝线不受低 pH 值的影响。合成缝线通过水解作用去除,这是炎症反应引起的自然结果
- 丝线比合成材料价格便宜
- 复丝缝线有利于细菌迁移到组织
- 复丝替代品:聚乙烯、涤纶、聚丙烯或膨体聚四氟乙烯 (e-PTFE)。这些替代品更加坚固,可以降低所引起的炎症反应,但患者的舒适度较低
- 氰基丙烯酸酯粘合剂可能宜用于覆盖粘膜性供体部位
- 基于纤维蛋白的粘合剂在口腔手术中已不再具有任何适应证
