Silver hydrogel dressings are antimicrobial, nonadherent, and have an absorptive capacity many times their weight. Fifty-nine (49.44 ± 16.85 years) foot and ankle patients with incisions >1 cm were prospectively enrolled to compare infection, scarring, and complication rates between the postoperative use of a silver hydrogel sheet (SHS) dressing and a standard petroleum-based (P) dressing. Overall, there were 5 (8.47%) infections; 4 (6.78%) superficial and 1 (1.69%) deep. The SHS group had 1 (3.45%) superficial infection, whereas the P group had 3 (10.00%) superficial infections and 1 (3.33%) deep infection. Infection incidence was similar for both groups (P = .37). However, in the P group, 3 (10.00%) patients developed wound dehiscence and 1 (1.69%) patient developed a fibrinous scab. Compared with SHS patients, the P patients had a greater incidence of incisional complications (1 [3.45%] vs 8 [26.67%], respectively; P = .03). The percent change in scar length was greater in the SHS group (18.04 ± 41.10%) when compared with the P group (2.00 ± 9.93%; P < .001) while the percent change in scar width was similar in the 2 groups (P = .19). The lower incidence of incisional complications and the greater reduction in scar length suggest that the inherent properties of the silver hydrogel dressing aid in postsurgical healing.
银水凝胶敷料具有抗菌、不粘连的特性，且其吸收能力是自身重量的许多倍。对59例（年龄49.44±16.85岁）切口大于1厘米的足踝部患者进行前瞻性研究，比较术后使用银水凝胶片（SHS）敷料和标准凡士林基（P）敷料时的感染、瘢痕形成及并发症发生率。总体而言，共有5例（8.47%）发生感染；4例（6.78%）为浅表感染，1例（1.69%）为深部感染。SHS组有1例（3.45%）浅表感染，而P组有3例（10.00%）浅表感染和1例（3.33%）深部感染。两组的感染发生率相似（P = 0.37）。然而，在P组中，3例（10.00%）患者出现伤口裂开，1例（1.69%）患者出现纤维痂。与SHS组患者相比，P组患者切口并发症的发生率更高（分别为1例[3.45%]和8例[26.67%]；P = 0.03）。与P组（2.00±9.93%）相比，SHS组瘢痕长度的百分比变化更大（18.04±41.10%；P < 0.001），而两组瘢痕宽度的百分比变化相似（P = 0.19）。切口并发症发生率较低以及瘢痕长度减少幅度更大表明，银水凝胶敷料的固有特性有助于术后愈合。
