The consensus conference on blood saving has allowed us to formulate some interesting guidelines. The autologous and homologous transfusion require the patient's consent. For volemic replacement crystalloid solutions are used for phlebotomies below 10-15%, and colloid solutions for those greater than 10-15% of the blood mass. Severe isovolemic hemodilution (Ht <20%) necessitates the reduction of the dosage of some drugs. A limit of Hb around 9 g/dl after phlebotomy may be acceptable in the absence of cerebral and coronary vascular disease. Phlebotomies are therefore possible also when the Hb values are 10 g/dl (Ht 30%). Hb values around 7 g/dl in the late postoperative period (from day 3 to 6) may be accepted only if well tolerated. The blood salvaged during surgery and at the beginning of the postoperative phase must always be centrifugated, washed and microfiltered. Subsequently, in the first 8 hours it is possible to reinfuse red cells after sedimentation and microfiltration. The techniques of predeposit, hemodilution and recovery are valid especially if associated with careful control of postoperative bleeding by means of aspiration under controlled pressure (at minimum negative values and sometimes positive ones), monitoring of blood loss from drainage and application of elastic compression bandages.
