ABSTRACT
Objective To explore the clinical efficacy and safety of closed negative pressure drainage(VSD) in the treatment of elderly patients with abdominal trauma and infection.Methods 82 elderly patients with abdominal trauma and infection were selected into clinical research,they were divided into two groups according to the treatment time number.41 cases of odd numbers were in the control group,they were given conventional dressing change and antibiotic therapy.41 cases of double numbers were in the observation group,they were given VSD therapy and antibiotic therapy.The clinical efficacy and safety after treatment was evaluated.Results The daily volume of the observation group [(48.67 ± 3.87) mL] was significantly increased compared with the control group,the dressing times [(8.59 ±1.04) times],hospitalization time [(18.33 ± 1.50) d] were significantly reduced compared with the control group,the differences were statistically significant(t =8.56,7.88,6.74,all P ＜ 0.05).The VAS score after treatment of the observation group was (3.38 ± 0.51)points,which was significantly lower than those before treatment and of the control group,the difference was statistically significant (t =8.06,7.56,all P ＜ 0.05).The infection control rate of the observation group was 92.68％,which was higher than that of control group,and the incidence of adverse reactions of the observation group was 4.88％,which was lower than that of the control group,the differences were statistically significant(x2 =6.87,7.69,all P ＜ 0.05).Conclusion The effect of vacuum sealing drainage technique in the treatment of elderly abdominal trauma and wound infection is significantly,it can effectively control the infection,reduce the number of dressing,relieve the pain of patients,and has the advantages of simple operation,high safety,which is suitable for promotion and application.
