Effect of bidirectional traction skin tension reduction technique in treatment of patients with poor healing at position of thoracic drainage tube

Objective To explore the effect of bidirectional traction skin tension reduction technique in the treatment of patients with poor healing at position of thoracic drainage tube.

Methods A total of 100 patients with poor healing at thoracic drainage tube after thoracoscopic surgery for lung cancer were randomly divided into observation group and control group, with 50 cases in each group. After preparing the wound bed, the control group was treated with traditional dressing change until wound healing, while the observation group was treated with bidirectional traction skin tension reduction technique to close the wound. The wound healing time, the number of dressing change, wound healing quality and satisfaction degree of wound nursing were compared between the two groups.

Results Wound healing time and the number of dressing change in the observation group were significantly shorter and less than those in the control group (P < 0.05). At 3 months of wound healing, the score of each item and total score of the Vancouver Scar Scale in the observation group were significantly lower than those in the control group (P < 0.05). The total satisfaction rate of wound healing in the observation group was 94.00%, which was significantly higher than 72.00% in the control group (P < 0.05).

Conclusion In the treatment of patients with poor healing at thoracic drainage tube after thoracoscopic surgery for lung cancer, the application of bidirectional traction skin tension reduction technology can promote wound healing, shorten wound healing time, improve wound healing quality, reduce scar hyperplasia, and increase patients' satisfaction degree to wound nursing.
