HighlightsCation Exchange Resins have been the mainstream treatment for chronic hyperkalemia.In 1987 the first case series of uremic patients with colonic perforations associated with the use of sodium polystyrene sulfonate was reported.The pathologic damage of Cation Exchange Resin in gastrointestinal tract goes from mucosal edema, ulcers, pseudomembranes, and the most severe transmural necrosis.Surgeons must avoid therapies with intestinal osmotic challenge implication in patients presenting gastrointestinal adverse reactions derived from Cation Exchange Resins.

IntroductionThe traumatic injuries to the tongue can go form section to partial or complete amputation, the latter being a rare presentation in the setting of facial trauma or even in patients with mental illness.Case reportWe present 25-year-old patient with traumatic partial amputation of the tongue who presented to the emergency department with successful surgical repair with good functional and esthetic outcome.DiscussionThe tongue can suffer a broad type of traumatic injuries, in the setting of active bleeding, the muscular planes must be closed with absorbable sutures to stop the hemorrhage and prevent hematoma formation. Tongue surgical repair in the setting of a total section requires integrity of arterial and venous flow, so anastomosis must be executed.ConclusionAmputation of the tongue can put the patient's life at risk and its management needs to be mastered by the surgeons treating polytraumatized patients.
