Methods The clinical data of 85 patients (51 males and 34 females; 4-75 years old) with wound who received negative pressure treatment between May 2009 and December 2010 were retrospectively analyzed. Results After receiving negative pressure treatment for once in 79 patients and twice in 6, the wound improved obviously. All cases received regular methods such as skin grafting or tissue flap transferring to reconstruct the wound. All of the 85 patients healed by first intention and the skin grafts or flaps survived well. Conclusion Negative pressure treatment is a simple, effective, stable and safe method for wound treatment, which can accelerate eliminating necrotic tissue of wound of different types at different parts, improve the wound condition and shorten the period of therapy.
ObjectiveTo investigate the effect of vacuum sealing drainage (VSD) combined with autologous platelet-rich plasma gel (PRP) on postoperative wound infection and chronic poor wound healing, so as to provide more economical and safe treatment in clinic.MethodsThe patients with postoperative wound infection and chronic poor wound healing in the Second Affiliated Hospital of Nanchang University and Sixth Affiliated Hospital of Sun Yat-sen University from September 2018 to July 2019 were collected, then were divide into PRP+VSD group and VSD group according to treatment methods. The patients in the PRP+VSD group were filled with PRP and activator calcium thrombin following debridement, then covered with silver ion dressing and continuous VSD; in the VSD group were directly covered with silver ion dressing and then continuous VSD. The general situations of patients in the two groups during the process of replacing the VSD and the wound condition during dressing replacing were observed.ResultsThere were 100 patients in this study, 50 in the PRP+VSD group and 50 in the VSD group. There were no significant differences in the age, gender, body mass index, wound area before treatment, and wound infection type between the two groups (P>0.05). Compared with the VSD group, the PRP+VSD group had higher score of fresh granulation tissue coverage area (P<0.05), shorter wound closure time (P<0.05), shorter wound healing time (P<0.05), lower pain score (P<0.05), and less hospitalization expenses (P<0.05), lower rates of second debridement (P<0.05) and recurrent infection (P<0.05).ConclusionAutologous PRP combined with VSD in treatment of postoperative wound infection and chronic poor wound healing could shorten growth time of wound granulation tissue, promote rapid wound healing, reduce cost, and provide an economic, safe, and effective treatment method for clinical practice.
ObjectiveTo explore the leakage management and skin care by improved homemade portable vacuum sealing drainage device used for enterocutaneous fistula, in order to solve such confusing problems as leakage collection and nursing for patients with inconvenient activity. MethodsThe homemade portable vacuum sealing drainage device was made by using hydrophilic fiber of silver ion antimicrobial dressings, leak-proof strings, skin protective film, transparent patches, sputum suction tube, bottle of portable infusion, and negative pressure drainage bottle. Between January 2011 and September 2013, patients with enterocutaneous fistula admitted into our hospital were divided into traditional treatment group and portable vacuum sealing treatment group according to the admission time, and traditional center negative pressure suction treatment and portable negative pressure drainage method were used respectively for the two groups of patients. We verified the effect of the mobile vacuum sealing drainage device through comparing these two groups in terms of wound healing time, redness, burst and impregnation of the skin. ResultsThe wound healing time was significantly shorter for patients in the portable vacuum sealing drainage treatment group (P<0.05), and patients in this group also had a lower occurrence of skin redness, impregnation and burst. ConclusionHomemade portable negative pressure drainage device for enterocutaneous fistula patients can reduce the incidence of skin complications such as redness, impregnation and burst, promote patients' activity, and reduce the patients' pain.
Objective To evaluate the clinical effect of vacuum sealing drainage (VSD) technology in the treatment of high perianal abscess. Methods A total of 38 cases of high perianal abscess who underwent surgery in our hospital from May. 2014 to Feb. 2016 were randomly divided into 2 groups: the VSD group (n=19) and the control group (n=19). The cases of VSD group were performed with closure of internal orifice+VSD technique, and the cases of control group were treated with radical operation of perianal abscess (low incision combined with high thread operation). The following indexes of cases in 2 groups were compared and analyzed, including postoperative pain score, wound healing time, postoperative anal function score, and prognosis. Results There were significant differences in pain score (3.53±0.70vs. 5.11±0.74), postoperative anal function score (0vs. 1), and wound healing time〔(27.58±4.95) dvs. (44.68±6.53) d〕between VSD group and control group,P<0.05. Compared with the control group, the pain score and anal function score of the VSD group were both lower, and the wound healing time was shorter. However, there was no statistically significant difference in incidence of fistula between the two groups〔5.3% (1/19)vs. 15.8% (3/19),P=0.60〕. Conclusion In the treatment of high perianal abscess, VSD technology can relieve pain in patients, shorten the wound healing time, protect the anal function, and the prognosis is as well as low incision combined with high thread operation, so VSD is a better treatment method for high perianal abscess.
Objective To observe the clinical effect of vacuum sealing drainage (VSD) in the treatment of mesh infection following inguinal hernia repair. Methods A total of 24 patients who suffered form mesh infection following inguinal hernia repair and got treatment in our hospital from February 2012 to December 2015 were collected and divided into 2 groups according to the type of treatment, 12 patients (13 sides) of VSD group received treatment of VSD, and 12 patients (13 sides) of conventional group received conventional treatment. Comparison between the 2 groups in mesh retention rate, the wound healing time, hospitalization cost, and hospital stay was performed. Results There was significant difference in mesh retention rate〔76.9% (10/13)vs. 30.8% (4/13)〕, the wound healing time〔(20.5±4.4) dvs. (29.7± 6.7) d〕, hospitalization cost〔(18 430.1±7 180.2) RMBvs. (12 201.1±6 453.2) RMB〕, and hospital stay〔(23.5±4.1) dvs. (30.7±6.5) d〕between the VSD group and conventional group (P<0.050). Compared with conventional group, the mesh retention rate and hospitalization cost were higher, the wound healing time and hospital stay were shorter in VSD group. Conclusions VSD can effectively control the mesh infection following hernia repair, improve the mesh retention rate. The VSD can also promote growth of granulation tissue in cavity, shorten the wound healing time and hospital stay, but has a high hospitalization cost than conventional treatment.
ObjectiveTo discuss nursing measures and experiences for children with extensive skin avulsion injury of lower limbs treated by vacuum sealing drainage (VSD). MethodsWe reviewed the perioperative nursing data of 48 child patients with extensive skin avulsion injury in lower limbs who underwent VSD treatment between December 2010 to October 2012. And the data were compared with those for 56 children with the same disease and treatment between January 2007 and November 2010. ResultsIn these 48 children, 19 received once, 23 received twice, and 6 received 3 times of vacuum sealing drainage. During the treatment, 5 drainage tubes were blocked and were solved with normal saline, and 3 drainage tubes had leakage and two of them were reconnected and the other one became normal after changing the dressing. For VSD, the time between being wounded and skin-grafting was 13.6 days, and the average hospitalization time was 24.3 days. Compared with the traditional method group, children in the VSD group had fewer drug changes during hospitalization, lower infection rate, and shorter hospitalization stay, and the differences were significant (P<0.05). ConclusionKeeping drainage tube airtight, normal and effective is as important as nutrition and mental nursing in the treatment of children's extensive skin avulsion injury in lower limbs, which can decrease infection rate, reduce average hospitalization time, and increase operative efficacy.
