Chain saw use may lead to hand-arm vibration syndrome. Objective tests revealed vasospasm in some chain saw operators, but blood flow and von Willebrand factor levels remained unchanged.

Area of Science:

  • Occupational Health
  • Vascular Physiology

Background:

  • Intensive chain saw use is linked to hand-arm vibration syndrome (HAVS), commonly known as vibration white finger.
  • HAVS is characterized by cold-induced vasospasm in the fingers.

Purpose of the Study:

  • To objectively assess cold-induced vasospasm in chain saw operators compared to controls.
  • To investigate the impact of chain saw use on finger blood flow and von Willebrand factor levels.

Main Methods:

  • Objective laboratory testing for cold-induced vasospasm in 12 chain saw operators and 12 matched controls.
  • Measurement of finger blood flow at varying temperatures and during hand vibration.
  • Analysis of plasma concentrations of von Willebrand factor antigen.

Main Results:

Related Experiment Videos

  • Five out of 12 chain saw operators showed abnormal results for cold-induced vasospasm, while all controls tested negative.
  • Finger blood flow measurements and von Willebrand factor levels did not differ significantly between operators and controls in the short or long term.

Conclusions:

  • Chain saw operation is associated with an increased incidence of cold-induced vasospasm.
  • Chain saw use does not appear to significantly alter finger blood flow or von Willebrand factor levels in the assessed parameters.
