What is the primary purpose of a JP drain following surgery for open reduction and internal fixation?

The primary purpose of a JP (Jackson-Pratt) drain following surgery for open reduction and internal fixation is to prevent fluid from accumulating in the wound. After such surgical procedures, it is common for fluids such as blood, serous fluid, or other exudate to collect at the surgical site. If these fluids accumulate, they can lead to complications such as hematomas or seromas, which may increase the risk of infection and delay the healing process. The JP drain helps facilitate the continuous removal of this fluid, allowing for better visualization of the surgical site, reducing the risk of infection, and promoting a more favorable healing environment.

While controlling bleeding is important in the immediate postoperative period, the JP drain's specific function is not primarily to limit bleeding but rather to manage fluid accumulation. Similarly, the drain is not intended for the administration of medications, nor does it eliminate the need for wound irrigations, as those may still be necessary for managing the surgical site, depending on the clinical situation.
