Application of vacuum sealing drainage in elderly patients with severe skin and soft tissue injury / 中华老年医学杂志

ABSTRACT

Objective To analyze the clinical effect of vacuum sealing drainage (VSD) on skin and soft tissue injury in elderly patients.Methods A total of 75 patients with severe skin and soft tissue injury who met the inclusion criteria were enrolled in this study.They were divided into two groups based on admission datesthe observation group (n =40,receiving VSD treatment,oddnumber date admission) and the control group (n=35,receiving routine dressing changes,even number date admission).The clinical indexes including pain score,wound healing time,infection rate and complications were analyzed and compared between the two groups.Results There was a significant difference in the average length of hospitalization between the two groups (21.3 days vl 30.7 days,t=7.60,P=0.0000).The infection rate was lower in the observation group than in the control group (12.5％ or 5/40 vs.54.3％ or 19/35,x2=13.12,P=0.0003).The incidence of complications was lower in the observation group than in the control group (15.0％ or 6/40 vs.42.9％ or 15/35,x2=5.87,P=0.0154).There were no deaths in the observation group,but one patient died from acute pulmonary embolism in the control group during hospitalization.Conclusions VSD can alleviate pain,reduce the infection rate,shorten the length of hospitalization and decrease bedridden complications in elderly patients with severe skin and soft tissue injury,and has valuable applications in clinical practice.
