Abstract:
OBJECTIVE: To evaluate the application value of finger systolic blood pressure(FSBP) in the diagnosis of vibration-induced vascular injury. METHODS: Thirty patients with vibration-induced vascular injury [vibration-induced white finger(VWF)] were selected as the case group by a non-randomized concurrent controlled trial, and 30 hand-transmitted vibration workers without VWF were selected as the control group. The FSBP test was performed on the tested hands of all subjects, and the FSBP index of each Finger(F_( i)) was measured. RESULTS: The F_i of the index finger, middle finger, ring finger and tail finger of the tested hand in the case group were lower than that in the control group(all P<0.01). In the case group, the F_i of index finger was lower than ring finger and tail finger(all P<0.01). The abnormal rates of F_i on the index, middle and ring fingers in the case group were higher than those in the control group(86.7% vs 10.0%, 76.7% vs 13.3%, 43.3% vs 10.0%, all P<0.01). The area under the receiver operator characteristic curve of the measured F_i of the index finger, middle finger, ring finger and tail finger were 0.884, 0.843, 0.764 and 0.687 respectively. The diagnostic cut off value of the F_i of index finger was 80.2%. The sensitivity and specificity were 86.7% and 90.0%, respectively. CONCLUSION: FSBP test has a good application value in the diagnosis of vibration-induced vascular injuries. It is suggested that the F_i of index finger be the first choice as the diagnostic index, and the abnormal value can be set at 80.0%.
