Which site is preferred for IV access in OMSA procedures?

The antecubital fossa is preferred for IV access in Oral & Maxillofacial Surgery Assistant (OMSA) procedures due to several favorable factors. This area is located at the crease of the elbow and contains significant veins, such as the median cubital vein, which is typically large and easily accessible. The placement of the IV in this location allows for a more stable and reliable access point, which is crucial during procedures that may require sedatives or anesthetics for patient comfort and safety.

Additionally, the antecubital fossa is less mobile compared to other areas like the wrist or the back of the hand, minimizing the chances of dislodging the IV during surgery. This stability is essential in maintaining continuous access to the bloodstream, especially if multiple medications are required throughout the procedure. Moreover, using veins in the antecubital fossa generally presents a lower risk of complications such as infiltration and phlebitis compared to veins found in the wrist or the back of the hand.

Using the back of the hand or the wrist for IV access can be less favorable because the veins in these areas are typically smaller, more superficial, and more prone to movement, increasing the difficulty of maintaining the IV line during a surgical procedure. The forearm
