Bromide concentrations of anesthetists
Serum bromide concentrations were measured in 12 operating room workers (primarily anesthetists) from two hospitals where halothane is administered daily. These halothane exposed workers were compared with ten healthy laboratory technicians. Serum bromide concentrations in the halothane exposed group ranged from 0.24 to 0.97 and averaged 0.53 mM/l. The corresponding values for laboratory workers ranged from 0.11 to 1.25 and averaged 0.38 mM/l. The two groups were not significantly different at the P < 0.05 level. Measurements of halothane concentration at the anesthetist's head level in an operating room from each hospital showed 30 and 104 ppm halothane.
