Background: Currently, the pneumatic tube system is used in the hospitals to reduce the transportation time of documents, medicines, and medical supplies. However, the transportation of blood gas within hospitals still depends on available hospital couriers, who may take long transport distances and cannot accommodate the moving promptly. Additionally, there is a lack of comparative data on blood gas values in pediatric patients transported via the pneumatic tube system versus hospital couriers.
Objectives: To compare the differences in blood gas transit time, blood gas values and transportation cost between a transit of blood gas sample via the customized container through pneumatic transportation system and via hospital couriers.
Method: An experimental study was conducted to compare the differences in blood gas transit time, blood gas values, and transportation costs between customized container through a pneumatic transportation system and hospital couriers for infants weighing 2 kilograms or more who needed blood gas analysis. Each sample of blood gas were transported by using both methods. Data were collected from 25 pairs of arterial blood gas samples and 36 pairs of venous blood gas samples from May 27 to December 5, 2023.
Result: Among 61 pairs of blood gas, mean + SD of transportation time by pneumatic tube system and by hospital couriers were 61.6 ± 4.9 and 148.2 ± 46.5 seconds, respectively (p value <0.001). Arterial and venous blood gas analyses (pH, PO2, PCO2 and HCO3 values) showed no statistically significant difference (p value <0.001) between the two transportation methods. There were no complications (hemolysis, clotting and air contamination) during blood gas transportation on both methods. The transportation cost using the pneumatic tube system was about half that of hospital couriers (approximately 27.5 and 50 Baht per round, respectively)
Conclusion: The blood gas values from transportation by customized container through pneumatic tube system did not differ from hospital couriers, and the transportation cost using the pneumatic tube system was lower than that of hospital couriers.
