Title Vibration-induced white finger and cold response of digital arterial vessels in occupational groups with various patterns of exposure to hand-transmitted vibration
Bibliographic information Apr. 1998, Vol.24, No.2, p.138-144. Illus. 18 ref.
Abstract The change in finger systolic blood pressure (FSBP) at 15 and 10░C as the percentage of the pressure at 30░C (FSBP%) was measured in 455 healthy referents and 822 workers exposed to hand-transmitted vibration from vibrating tools. The prevalence of white finger was 1.1% for the referents and ranged from 9.0% to 51.6% for the vibration-exposed groups. After adjustment for age, smoking and drinking habits, the FSBP% was significantly lower in the vibration-exposed groups than in the reference group. Groupwise, the FSBP% was inversely related to the prevalence of white finger, the estimated exposure and total operating time. FSBP measurement during cold provocation is a useful laboratory test for white finger. A quantitative relationship between cold-induced digital arterial hyperresponsiveness and occupational exposure to hand-transmitted vibration was suggested. Topics: age; alcoholism; blood pressure; blood vessels; cold pressor test; dose-response relationship; fingers; hand-arm vibration; Raynaud's phenomenon; smoking; vibrating tools.
