A new method for the experimental assessment of finger haemodynamic effects induced by a hydraulic breaker in operative conditions

Background Injuries due to high-pressure injections are frequently underestimated occupational accidents, which may have disabling outcomes. Methods The occupational injuries logbooks of two shipyards were examined. Twelve accidents due to the utilization of high-pressure equipment were reported. Data were obtained by reviewing the employers’ logbooks and hospital records. Results Contaminants were epoxy paint and stucco, paint solvent, hydraulic and industrial oil. In three cases, the palm was injured and the fingers in nine. In 91% of cases, the accident occurred in the last 2 hr of the work shift. Mishandling (n¼9) and rupture of the high-pressure equipment (n¼3) were the causes. Mean time to medical treatment was 42.5 hr (SD 56.0). Ten workers were permanently disabled. Conclusions Prompt surgical intervention with debridement and decompression was done in two workers, who healed completely. The ten patients who were not treated immediately eventually experienced a high rate of disability and five of them also suffered amputation
