Standard operating procedures for autologous stem cell transplantation (SCT) aim to guarantee best possible engraftment. Three procedures are routinely used for transplant infusion: regular bag infusion (Procedure 1), injection via syringe (Procedure 2), and combination of regular bag infusion and syringe (Procedure 3). We conducted a retrospective analysis of all autologous stem cell transplants done in the hematology department of the Vivantes Clinic Neukoelln in Berlin, Germany, between January 1, 2016 and March 4, 2017. Of the total of 69 patients, 17 underwent Procedure 1, 32 Procedure 2, and 20 Procedure 3. Although speed of transplant reinfusion differed significantly between procedure types, these differences had no effect on duration of leukopenia. However, duration of leukopenia did correlate with need for blood transfusion and use of antibiotics. Our findings contradict the general perception that very rapid reinfusion is necessary. Nevertheless, considering the limitations of this study (retrospective, single center, small sample size) and that longer duration of aplasia is associated with greater need for intervention, efficient transplant reinfusion is advisable. More research is needed regarding timeliness and type of procedure used. © 2021. Japanese Society of Hematology.
