An apparatus for supporting an extremity during tissue debridement and capturing fluid and tissue resulting from tissue debridement includes an extremity-supporting base and barrier shroud. The apparatus can be used in tissue debridement procedures to contain and control drainage of fluid and tissue. The apparatus supports and encloses a patient extremity, such as an arm or a leg. The base has a length, proximal end (i.e., nearest the patient's body), and distal end (i.e., farthest from the patient's body). The shroud has a top portion, bottom portion, and shroud drainage opening. A method includes debriding tissue from a patient extremity while supported by the base and at least partially enclosed within the barrier shroud, which acts as a shield for fluid and tissue emanating from the extremity. Fluid and tissue exits the shroud through a shroud drainage opening.
