This study is intended to present a rare but possible respiratory complication during a shoulder arthroscopy performed in the beach chair position. Fluid leaked into the mediastinum during the procedure when the infusion pump was being used, which caused respiratory difficulty. Treatment was conservative, with extubation delay, stay at the Intensive Care Unit, diuretic drugs, and support action. In the fourth postoperative day, the patient was asymptomatic regarding such complication.
