概括

落在地板上的口腔粘膜移植 (BMG) 显示没有致病细菌. 赫西丁 (CHX) 有效地去污染了移植物,这表明在适当清洗后安全地重复使用意外污染的BMG.

科学领域:

泌尿器科泌尿器科泌尿器科泌尿器科
微生物学微生物学
手术创新在外科创新.

背景情况:

口腔粘膜移植 (BMG) 在重建性手术中使用.
在手术过程中,BMG的意外污染会造成手术部位感染 (SSI) 的风险.
对于受污染的移植物来说,清除污染的协议至关重要.

研究的目的:

为了评估意外掉落的BMG的微生物污染.
为了评估2%的化 (CHX) 作为一种消毒方法.
为了确定 gentamicin 灌对预防 SSI 的影响.

主要方法:

Burn Injuries

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
