Abstract: Objective To investigate the clinical efficacy of vacuum sealing drainage(VSD) in the treatment of postoperative wound healing of chest wall tuberculosis.Methods From January 2014 to may 2021,40 patients with poor wound healing after chest wall tuberculosis debridement in Hebei chest hospital were selected and randomly divided into observation group and control group,with 20 patients in each group.The observation group was treated with vacuum sealing drainage,and the control group was treated with general surgical dressing changeThe differences of pain perception,dressing time,healing evaluation after 7 days,secondary suture time and hospitalization time between the two groups were compared.Results The pain perception of dressing change was （3.27±0.80 ）in the observation group and （5.67±0.72 ）in the control group.There was significant difference between the two groups(P<0.05);The dressing change time was (5.33±14.08) minutes in the observation group and (22.07±2.52) minutes in the control group.There was significant difference between the two groups(P<0.05).The second suturing time of the wound was (14.06±2.14) days in the observation group and (23.14±3.38) days in the control group,which was statistically significant(P<0.05);the length of hospital stay was(23.80±2.81) days in the observation group and (35.73±4.43) days in the control group,which was statistically significant(P<0.05);there were 17 patients in the observation group and 10 patients in the control group(P<0.05).Conclusion The application of VSD in the treatment of chest wall tuberculosis,promote wound healing effect is significant.
