What is the correct composition of the tumescent solution used in an endoscopic brow lift?

The correct composition of the tumescent solution used in an endoscopic brow lift is characterized by a balance of saline, lidocaine, and epinephrine. The tumescent solution is designed to provide local anesthesia while also facilitating hemostasis and minimizing surgical bleeding.

In particular, the first option has a specific combination of 200 ml of saline which serves as the base solution to create a tumescent effect, increasing the volume in the subcutaneous space and making the tissue easier to manipulate during surgery. The inclusion of 1 amp of epinephrine is crucial as it acts as a vasoconstrictor, reducing bleeding during the procedure by shrinking blood vessels in the area where the surgery is performed. The addition of 25 ml of 1% lidocaine provides effective pain relief, ensuring patient comfort throughout the procedure.

This composition reflects standard practice in cosmetic procedures like an endoscopic brow lift, where maintaining hemostasis while providing adequate anesthesia is vital for patient outcomes. The other options either do not align with the typical recommended volumes or concentrations of the components for effective local anesthesia and vasoconstriction in this setting.
