Abstract

The use of pneumatic tube system (PTS) transport has gained considerable popularity in modern hospitals but is also associated with sample hemolysis. The potential contribution of PTS-associated acceleration forces to high hemolysis rates observed in the emergency department (ED) has not been investigated before and can be easily examined nowadays using smartphone applications. The first aim of our study was to investigate whether our PTS induces hemolysis of patient samples obtained from our ED. We also explored a potential correlation between hemolysis index (HI) on the one hand and acceleration forces during PTS transport or other potential causes of hemolysis related to patient characteristics on the other for two different blood sampling techniques. Blood samples from 100 ED patients were collected in one Sarstedt S-Monovette® serum tube (PTStransported to laboratory) and two BD Vacutainer® serum tubes (one PTS-transported and one hand-carried). For all serum samples HI was measured. A smartphone was sent along with the samples in order to register accelerations during transport. Patient's erythrocyte sedimentation rate (ESR), mean corpuscular volume (MCV), hematocrit, total cholesterol, low density lipoprotein (LDL), and ...Continue Reading
