Abstract:
Objective To investigate the changes of serum and urine fluorion organic fluoride poisoning by inhaling, and to probe into the clinical application value of concentrations in different degrees and at different time in patients with acute evaluating the sertm and urine fluorion concentration in acute organic fluoride poisoning by inhaling. Method A study was carried out in 23 patients, who suffered from acute organic fluoride poisoning by inhaling and were admitted Zhejiang Quhua Hospital, from December 2000 to December 2008. According to the occupational acute organic fluoride poisoning diagnostic criteria(GBZ66-2002),23 patients were divided into mild poisoning group,moderate poisoning group and severe poisoning group. Serum and urine fluorion concentration of patients at 1,2,3,4,5 d after poisoning were measured by using Ion-Selective Electrodes. Fluorion concentration of 10 staffs of Fluorine chemical company was also measured at the same period as the control group. The values of serum and urine fluorion concentration were analyzed. Differences in serum and urine fluorion concentration between groups at different time points were compared by repeated measures ANOVA and variability were deemed as statistical significance when P ＜ 0.05. Results Compared with mild poisoning group, there was no statistically significant difference ( P ＞ 0.05) in serum and urine fluorion concentration at the same time point in 1 to 5 days after poisoning in moderate poisoning group, but there was statistically significant differences ( P ＜ 0.05 or P ＜0.01) in severe poisoning group. Compared with moderate poisoning group, there was statistically significant difference ( P ＜ 0.05) in serum and urine fluorion concentration at the same time point in 1 to 5 days after poisoning in severe poisoning group. Serum fluorion concentration in 1 to 5 days after poisoning in each poisoning groupswere statistically higher than those in control group ( P ＜ 0.05), but there was statistically significant elevation ( P＜ 0.05) in urine fluorion concentration only in 1 day in mild poisoning group, in 1 to 3 days in moderate poisoning groups, in 1 to 5 days in severe poisoning group. Conclusions Serum fluorion concentration can be used as the severity index of diagnosis and determine the extent in 5 days after acute organic fluoride poisoning by inhaling,and urine fluorion concentration can also be used as diagnostic indicators of intoxication, but only in earlier stage or severe poisoning.
