To describe the wide variation of histologic characteristics produced by electrosurgical burns.
Retrospective analysis.
University-associated teaching hospital.
Pigs and dogs.
Various power settings were employed with both monopolar and bipolar electrodes to incur electrosurgical damage. Animals were followed for up to 96 hours after injury.
Histologic analysis yielded characteristics of electrosurgical damage including areas of complete necrosis and coagulation, perivascular changes, endothelial damage, and hyperchromic pyknotic nuclei. White cell infiltration was seen only at the margin of necrotic zones of coagulation.
The wide spectrum of histology from electrosurgical burns is primarily a result of the area that is sampled. Surgeons should actively investigate any postsurgical complications involving electrosurgery to obtain a definitive cause.

使用单极和双极电极，采用不同的功率设置造成电外科损伤。损伤后对动物进行长达96小时的观察。
组织学分析得出电外科损伤的特征，包括完全坏死和凝固区域、血管周围变化、内皮损伤以及核固缩深染。仅在凝固性坏死区域边缘可见白细胞浸润。
电外科烧伤组织学表现的广泛差异主要是取样区域不同所致。外科医生应积极调查任何涉及电外科手术的术后并发症，以明确病因。
