BACKGROUND/AIMS: The objective of this study was to compare the depth and width of thermal spread caused on rat uterine tissue after application of 3 different electrosurgical generators.
Alsa Excell 350 MCDSe (Unit A), Meditom DT-400P (Unit M), and ERBE Erbotom VIO 300 D (Unit E) electrosurgical units (ESUs) were used. The number of Wistar Hannover rats required to obtain valid results was 10. The primary objective of the study was to compare the 3 ESUs using the same instrument and the same waveform. The secondary objective of the study was to compare the differences between monopolar and bipolar systems of each ESU separately using the same waveform.
The thermal spread caused by each ESU using monopolar instruments with continuous and interrupted waveforms was significantly different. Among the 3 devices, Unit A caused the largest thermal uterine tissue spread. On the other hand, Unit E caused the most superficial thermal tissue spread, and the smallest thermal spread among all ESUs.
Surgeons should note that different ESUs used with the same power output might create different thermal effects especially in the monopolar configuration within the same waveform, for the same duration, and with the same instrument.
背景/目的：本研究的目的是比较3种不同的电外科发生器作用于大鼠子宫组织后产生的热扩散深度和宽度。
使用Alsa Excell 350 MCDSe（A组）、Meditom DT - 400P（M组）和ERBE Erbotom VIO 300 D（E组）电外科设备（ESU）。获得有效结果所需的Wistar Hannover大鼠数量为10只。本研究的主要目的是使用相同的仪器和相同的波形比较这3种ESU。本研究的次要目的是使用相同的波形分别比较每个ESU的单极和双极系统之间的差异。
使用具有连续和间断波形的单极仪器时，每个ESU引起的热扩散有显著差异。在这3种设备中，A组引起的子宫热组织扩散最大。另一方面，E组引起的热组织扩散最浅，且在所有ESU中热扩散最小。
外科医生应注意，相同功率输出下使用不同的ESU可能会产生不同的热效应，特别是在相同波形、相同持续时间和相同仪器的单极配置中。
