Transporting blood components through a pneumatic tube system
Introduction: Urgent blood component transfusions may be life-saving for patients in hemorrhagic shock. Measures to reduce the time taken to provide these transfusions, such as uncrossmatched transfusion or abbreviated testing, are available. However, transport time is still an additional delay and the use of a pneumatic tube system (PTS) may be an alternative to shorten the transport time of blood components.
Objectives: To assess pneumatic tube system transportation of blood components based on a validation protocol.
Methods: Pre- and post-transport quality control laboratory parameters, visual appearance, transport time and temperature of the packed red blood cells (RBCs), thawed fresh plasma (TFP), cryoprecipitate (CR), and platelet concentrate (PC) were evaluated. Parameters were compared between transport via pneumatic tube and courier.
Results: A total of 23 units of RBCs, 50 units of TFP, 30 units of CR and ten units of PC were evaluated. No statistically significant differences were found between pre- and post-transport laboratory results. There was also no difference in laboratory parameters between transport modalities (PTS versus courier). All blood components transported matched regulatory requirements for quality criteria. The temperature during transport remained stable and the transport time via PTS was significantly shorter than the courier’s transport time (p < 0.05).
Conclusion: The PTS was considered a fast, safe and reliable means of transportation for blood components, also securing quality prerequisites.
