AbstractEach year in France 6000 to 9000 patients are splenectomised or spleen embolized. As spleen has immunological functions, it contributes to protect against infections. Thus, hypo or asplenia increase the risk of infection, especially the risk of Overwhelming Post-Splenectomy Infection (OPSI). OPSI is a medical emergency, characterized by aspecific symptoms, which may rapidly progress to fulminant infection and death in 50% of cases within 48 h. Encapsulated bacteria as Streptococcus pneumoniae, Haemophilus influenzae and Neisseria meningitidis are most of the time responsible of these infections in asplenic patients. To prevent OPSI, several measures are essential and must begin before a scheduled surgery or just after an urgent splenectomy. Patients must carry a card. The first proposed prevention measure is to enhance partial surgery when it's possible. Then, the two other measures, antibiotic prophylaxis and vaccination, shall be implemented whatever is the indication of surgery. Postoperative antibiotic prophylaxis by phenoxymethyl-penicillin is prescribed for two years minimum and lifelong prophylaxis should be offered to high risk of pneumococcal infection patients. Pneumococcal, H. influenzae type b and meningococcal vaccination should be administered 2 to 6 weeks before scheduled splenectomy and 2 weeks after urgent surgery. Yearly, patients must receive Influenza vaccination. As an interindividual variation exists in vaccinal response, measurement of serotype-specific antibodies can be used, if available, to individualized risk patients and to organize revaccination. Finally, to prevent OPSI, patient and next-of-kin must be educated about prevention measures and infectious risk to optimize patient's compliance.Copyright © 2013 Société française d’anesthésie et de réanimation (Sfar).
