Abstract Introduction: there is growing evidence for the usefulness of plasmapheresis in different clinical entities. There are many international records of plasmapheresis, but the information in Colombia and even in Latin America, is limited. Objective: to perform a descriptive analysis of the experience in plasmapheresis of an academic institution in Bogotá, Colombia. To analyze the characteristics of the technique, indications, complications and demographic characteristics of patients. Material and methods: descriptive analysis of plasmapheresis sessions performed in the Hospital Universitario San Ignacio in patients older than 18 years during the period from August 2008 to August 2011. All sessions were conducted by the technique of transmembrane filtration. No anticoagulation was used in any of them. Results: 278 sessions of plasmapheresis were analyzed in 33 adult patients over a period of three years. 69.7% of patients were female, with mean age of 42 years. 57% of the sessions were conducted in patients diagnosed with myasthenia gravis and alveolar hemorrhage. The average volume of plasma exchange was 1.28. 9.3% of the sessions presented at least one complication. Hypotension was frequently documented in the sessions performed with 3.5% albumin. 12% of electrolytes records had hypocalcemia and 47% hypermagnesemia. There were no therapy-related deaths and despite the non-use of anticoagulant, no clotting of the circuit in any of the sessions was presented. Conclusions: Given our experience, we believe that plasmapheresis is a safe therapy. It is necessary to assess the need for administration of anticoagulant to the plasmapheresis circuit since no clotting in it in any session was documented and its use could be associated with adverse events. Continuous monitoring of electrolytes is essential and its replacement should be individualized. (Acta Med Colomb 2014; 39: 29-34).
