The effect of negative pressure sealing drainage technology in the repair of deep burn wounds
Objective To study the role and effect of negative pressure sealing drainage technology in the repair of deep burn wounds,in order to provide reference for the treatment of deep burn wounds.Methods A total of 90 deep burn patients admitted to Tengzhou Central People's Hospital from January 2021 to December 2022 were selected as the study subjects.According to different wound repair methods implemented,the patients were divided into observation group and control group,with 45 cases in each group.The control group received routine scab removal and skin grafting treatment,while the observation group received negative pressure sealing drainage surgery for treatment on the basis of the control group.The incidence of complications,pain degree score,skin grafting healing time,hospital stay and various vital signs before and after surgery of the two groups were compared.Results The incidence of complications in the observation group was 4.44％,which was lower than 17.78％in the control group,and the difference was statistically significant(x2=4.050,P＜0.05).The pain degree score,skin graft healing time and hospital stay in the observation group were better than those in the control group,and the differences were statistically significant(P＜0.05).Before operation,there were no significant differences in the various vital signs between the two groups(P＞0.05);after surgery,the various vital signs in both groups were better than those before surgery,and the observation group was better than the control group,and the differences were statistically significant(P＜0.05).Conclusion Negative pressure sealing drainage technology could ensure close adhesion between the wound and the transplanted skin,fully drain necrotic tissue and subcutaneous hematoma,create a good recovery environment for granulation and microvascular regeneration,does not require local dressing changes and effectively improve the survival rate of skin grafting,shorten hospital stay,which was worthy of clinical promotion and application.
