研究目的:

本研究旨在评估早期彻底清创、负压引流与局部抗蛇毒血清浸润联合应用对中华眼镜蛇咬伤后组织坏死的早期干预效果,明确该方案在减少坏死组织体积、缩短创面愈合时间、降低致残率及改善患者预后方面的临床价值,为优化蛇伤局部坏死治疗策略提供循证依据。  

Objectives of Study:

To evaluate the efficacy of the combined application of early radical debridement, negative pressure drainage, and local antivenom infiltration in the early intervention of tissue necrosis after Naja atra bite, and to clarify the clinical value of this protocol in reducing necrotic tissue volume, shortening wound healing time, reducing disability rate, and improving patient prognosis, so as to provide evidence-based basis for optimizing the treatment strategy of local necrosis after snakebite.

测量指标:

Outcomes:

指标中文名:

治疗后7天坏死组织体积变化率

指标类型:

主要指标

Outcome:

Rate of change in necrotic tissue volume at 7 days post-treatment

Type:

Primary indicator

测量时间点:

治疗后7天

测量方法:

采用三维扫描或透明网格纸描记法测量创面坏死组织面积,结合创面深度计算坏死组织体积,计算治疗后7天坏死组织体积较基线的变化率。

Measure time point of outcome:

7 days post-treatment

Measure method:

The area of necrotic tissue on the wound surface is measured using three-dimensional scanning or transparent grid paper tracing. The necrotic tissue volume is calculated by combining the wound depth, and the rate of change in necrotic tissue volume at 7 days post-treatment compared with baseline is computed.

指标中文名:

创面完全上皮化时间

指标类型:

次要指标

Outcome:

Time to complete wound epithelialization

Type:

Secondary indicator

测量时间点:

从入组至创面完全上皮化的时间

测量方法:

每日观察创面,记录创面完全上皮化(无渗液、无坏死组织、创面完全被新生上皮覆盖)的时间。

Measure time point of outcome:

From enrollment to complete wound epithelialization

Measure method:

The wound is observed daily, and the time to complete wound epithelialization (defined as no exudate, no necrotic tissue, and complete coverage of the wound by new epithelium) is recorded.
