Many bipolar sterilization failures have occurred because of incomplete desiccation of the endosalpinx. This study compared the effect upon human fallopian tubes of different waveforms of electrical energy at advancing power settings. When the Valleylab SSE2-L generator was attached to the Kleppinger bipolar forceps, complete desiccation was confirmed with the power set at 25 W in a cutting waveform. Other waveforms (coagulation and blend) failed to complete the task at the same power setting. An inline current meter assures the operator that all the available energy is delivered. This information should help to reduce bipolar sterilization failures.
许多双极绝育失败是由于输卵管内膜干燥不完全所致。本研究比较了在递增功率设置下不同电能波形对人体输卵管的影响。当Valleylab SSE2-L发生器连接到Kleppinger双极钳时，在切割波形下将功率设置为25 W可确认完全干燥。其他波形（凝固和混合）在相同功率设置下未能完成任务。内置电流表可确保操作员所有可用能量均已输送。这些信息应有助于减少双极绝育失败。
