Abstract:Role of negative pressure dressing and moist wound healing are well established in the treatment of both acute and chronic wounds with certain advantages and disadvantages in both the techniques. Both these techniques prevents wound colonization, but the negative pressure dressing method has proved to have a greater potency to remove secretions, prevent wound invasion and eradication established infection. In both these techniques there is no accessibility to wound environment. Limited access dressing (LAD) is… Show more
“…For applying LAD over extremity wounds [10][11][12] (Figure 1), either ethylene oxide presterilized customized polythene bag are used or based on the shape, size and site of the wound customized polythene bag is sealed using semi automatic plastic sealing machine and sterilized by immersion in 2.45% w/v glutaraldehyde solution for 20 minutes. Two thick nasogastric tubes (extra holes are made if required) after placed in between the bag and wound are brought out through the polythene cover at the predetermined site.…”

“…The efficacy of LAD in eradication of resistant bacterial infections [10], was studied (2010; unpublished) on 60 patients with one or more wounds. Out of 60 patients, in 57 (95%) patients bacterial growth was detected, treatment with LAD for 10 days resulted in no growth in 34/57 (59.6%) patients, and reduction in the number of organisms in 19/57 (33.33%) patients.…”

“…In a preliminary study [10] (August 2005, September 2007 at Burns ward Kasturba Medical College, Manipal) to prove leech effect two identical groups of 54 thermal burns (less than 48 hrs duration) patients were made: Control group and LAD treated group each comprising of 27 extremities burn matching in age, sex and TBSA burn. There was no statistically significant difference in occurrence of SIRS on Day 1 (control group 26 vs LAD group 23; p value 0.742), but on Day 5 the difference in occurrence of both SIRS (control group 18 vs LAD group 23, p value 0.029) and occurrence of organ Dysfunction (control group 12 vs. LAD group 4; p value 0.017) was significant.…”

“…Since LAD combines principles of both moist wound dressing and negative pressure dressing with some extra advantages over both these methods, it offer a consistent and better chance of limb salvage. Negative pressure of LAD along with placement of drains in infectesfascial planes of foot (concept of target tissue [10]) and leg helps to stop the spread of infection along fascial/ peritendinous planes.…”
Moist wound healing and Negative pressure wound therapy (NPWT) are newer concepts in wound management. NPWT has been shown to be a safe and effective treatment for complex diabetic foot wounds. Limited Access Dressing (LAD) combines the principles of moist wound healing and NPWT along with a provision of two additional ports (1216Frtube) for instilling antimicrobial solution of choice and alters the wound environment without any need to change the dressing. LAD utilizes definite intermittent negative pressure schedule (30 minutes of negative suction and 3½ hours of rest period; minimum 30mmHg of negative pressure). Intermittent negative pressure regimen of LAD reduces the total duration of negative pressure and need for specially designed suction devices. The LAD design has notable advantages, while avoiding some major disadvantages such as an inaccessible offensive smelling wound environment and relatively high treatment cost.
