Pin-site infection is one of the most troublesome complications of external fixation. The present study aimed to compare the rate of pin-site infection following silver sulfadiazine with dry dressing.
This was a prospective randomized controlled study among 30 clients that compared the outcome of pin dressing using silver sulfadiazine (study group = 15) with dry dressing (control = 15). All eligible subjects of open tibial fracture had an emergency debridement with external fixation. Pin tract infection was considered to be present if superficial inflammation (erythema, cellulitis), serous or purulent discharge occurred around a pin site and deep infection of osteolysis around the pin, and sequestrum.
Seven subjects (46.7%) had pin-site infection in the present study group while six subjects (40.0%) had it in the control group, with comparable severity.
There was no significant difference in prevalence of pin-site infection between both groups (p = 0.97). Therefore, either silver sulfadiazine or dry dressing could be advocated.
针道感染是外固定最棘手的并发症之一。本研究旨在比较磺胺嘧啶银与干性敷料治疗后的针道感染发生率。
这是一项针对30例患者的前瞻性随机对照研究，比较了使用磺胺嘧啶银进行针道换药的结果（研究组=15例）与干性敷料（对照组=15例）。所有符合条件的开放性胫骨骨折患者均接受了外固定紧急清创术。如果针道周围出现浅表炎症（红斑、蜂窝织炎）、浆液性或脓性分泌物，以及针周围的骨溶解和死骨形成等深部感染，则认为存在针道感染。
本研究组有7例患者（46.7%）发生针道感染，而对照组有6例患者（40.0%）发生针道感染，严重程度相当。
两组针道感染发生率无显著差异（p=0.97）。因此，磺胺嘧啶银或干性敷料均可采用。
