What is the purpose of keeping one arm on an arm board during surgery?

The purpose of keeping one arm on an arm board during surgery is primarily to provide access for intravenous infusion of fluids, blood, or medications. This positioning allows healthcare providers to have a stable and accessible site for intravenous access, which is critical for administering necessary treatments throughout the surgical procedure.

Utilizing an arm board ensures that the arm remains in a fixed position, preventing movement that could disrupt the IV line or cause complications such as infiltration or phlebitis. Additionally, this setup helps maintain a clear field for surgical teams, minimizing the risk of accidental injury to the patient or interference with surgical instruments.

Maintaining the arm on the board also supports efficient monitoring of fluid administration and allows for easier assessment of the infusion site without the need to reposition the patient's arm constantly. This contributes to overall patient safety and optimal surgical outcomes.
