Abstract: ［Abstract］Objective〖HTSS〗To observe the effect of cold and circulatory pressure therapy on soft tissue swelling of ankle fracture.
Methods〖HTSS〗Sixty-two patients with ankle fracture were randomly divided into the experimental group and the control group, each with 31 patients. After admission to the experimental group, the patients in the experimental group were treated with detumescence by circulating pressure cold therapy device. Patients in the control group were given routine orthopedic care and treated with ice packs. Visual Analogue Scale(VAS) score was used for pain assessment before,24,48,and 72 hours after treatment. The swelling of the affected limb was evaluated by measuring the swelling value of fixed point position(the circumference of medial and lateral malleolus).The incidence of tension blisters and preoperative waiting time were compared between the two groups.
Results〖HTSS〗With the extension of time, the swelling value and VAS score of affected limb in both groups showed a decreasing trend, and the reduction range of the swelling value and VAS score of affected limb in the experimental group was greater than that in the control group, and the interaction difference between groups, time points and between groups was statistically significant(P＜0.05).The incidence of tension blisters in the experimental group was significantly lower than that in the control group, and the preoperative waiting time was shorter than that in the control group, with statistically significant difference(P＜0.05).
Conclusion〖HTSS〗Early application of circulatory compression and cold therapy in patients with ankle fractures is beneficial to reduce the pain and soft tissue swelling and reduce the incidence of tension blisters.
