Analysis of Airborne Dust as a Result of Plaster Cast Sawing

SUMMARY – Plaster splints are used daily in surgical and orthopedic fi elds in order to immobilize injured children and adults. Th e aim of this study was to measure the aerodynamic diameter and concentration of dust particles in the air caused by sawing plaster splints (calcium sulfate dehydrate). We performed fractional measurements of airborne dust particles. Th e measured particles, which can potentially be inhaled, may have a specifi c negative eff ect on human health. Measurements were conducted in laboratory research facilities that simulated hospital conditions within a casting room and the associated waiting room. Measurements within the casting room were made using two particle collector devices and one laser photometer. Th e measurement for the simulated waiting room was performed using the same principles and devices. Th e collected plaster dust particles diff ered in aerodynamic diameter and concentration according to the various locations observed. Th e highest concentration of particles of all sizes was recorded at the site of cast sawing. Th ere was direct correlation between distance from the source and concentration of airborne particles ; this concentration was lowest in the waiting room. Th e concentrations of plaster dust recorded were lower than the recommended minimal limit values for total and respiratory fractions in Croatia. Accordingly, it can be assumed that sawing of plaster splints has no harmful health eff ects on the exposed patients and health personnel.
