To avoid inadvertent cutting of vessels before adequate sealing, what is essential during bipolar activation?

• A. Ensure entire activation cycle is completed prior to cutting.
• B. Cut before activation completes.
• C. Never seal vessels.
• D. Always perform a second activation after cutting.

Answer: (A)

During bipolar vessel sealing, energy is delivered to the vessel to denature collagen and elastin in the vessel wall, creating a reliable seal. The full activation cycle allows heat and tissue effects to propagate and establish a secure hemostatic bond. If you cut before this cycle finishes, the seal may be incomplete and the vessel can bleed or re-open. Therefore, you wait for the entire activation to complete while the vessel is still grasped and compressed, then cut once the seal is established. Cutting early, never sealing, or adding a second activation after cutting does not reliably ensure hemostasis and can increase the risk of vessel injury or bleeding.
