What is a negative effect of excess bleeding during surgery?

Excess bleeding during surgery can significantly impair the surgeon's ability to visualize the surgical site clearly. Proper visibility is crucial for the execution of precise surgical techniques and for ensuring that all necessary structures are properly addressed. When bleeding occurs excessively, it can obscure the view of the area being operated on, making it difficult to differentiate between healthy and pathological tissues, to place sutures accurately, or to follow the planned surgical protocol. This lack of clarity can lead to improper maneuvers, increased risk of complications, and an overall decrease in the quality of the surgical outcome.

In contrast, while increased patient anxiety, incomplete treatment, and longer surgery time may also be associated with excessive bleeding, the most immediate and direct impact is the inability to see the surgical site clearly, which can compromise the entire procedure.
