Role of the Surgical Glove in Modified Vacuum-Assisted Wound Healing
Article information
Abstract
Vacuum-assisted wound healing has been proven to be more efficacious than conventional dressings. Vacuum dressing has been frequently modified given the restrictions in resources available. Here we present a modified method of vacuum dressing by using surgical or gynaecological gloves for lower and upper limb wounds. Vacuum dressing was applied with parts of a surgical or gynaecological glove and Opsite with T-tailing of the suction outlet. Vacuum-assisted wound healing using the surgical gloves showed relatively good wound healing in the amputation stump, finger, arm, and leg in the cases studied.
INTRODUCTION
Vacuum-assisted wound healing [1,2] has been proven to be more efficacious than conventional dressings. The surgical glove is cheap, easily available, sterile, elastic, and effectively seals once snugly fit. It is malleable such that it can be applied to a part of the body with a multifaceted contour, and it takes its shape under a vacuum while maintaining it. On this basis an attempt has been made to use a surgical or gynaecological glove as a modified form of vacuum-assisted wound healing with the help of Opsite and a T-tail configuration of the suction tubing outlet [3].
IDEA
Under aseptic conditions, the wound was thoroughly debrided and cleaned of slough and necrotic tissue. The wound base was covered with a sterile sponge placed in two layers. An infant feeding tube or suction catheter or Ryle's tube is placed in between the two layers. The sponge is held in place over the wound by applying thin Opsite strips like Steri-Strips. A sterile surgical or gynaecological glove of appropriate size is taken and inserted over the foot, hand, or amputation stump (Fig. 1). The suction tube is brought out from the edge of the glove. A 15 cm×28 cm piece of Opsite is taken and cut in half along its length and applied covering entire margin of the stretched glove circumferentially. The edges can also be fixed with skin staples. The Opsite should not be put too tight in order to prevent skin excoriation and peripheral edema.
Measurements and oblique slit mark on gloves
Various measurements of the surgical and gynaecological gloves have been marked. The gloves can be cut and applied according to the length and size of the wound. An oblique cut (red line) can be made at an appropriate angle to obtain a wider opening in the arms of the gynaecological gloves and can be applied to areas like amputation stump ulcers.
Surgical gloves are available in various sizes. Gynaecological gloves of 7 ½ and 8 ½ sizes can be applied for lengthy wounds.
The arms of the gynaecological gloves can be cut and applied in an overlapping manner over the ends, in a telescopic fashion so that larger lengths can be constructed, and there is very minimal leakage through the overlapping ends of the gloves. This overlapping holds a vacuum and prevents leakage when a continuous suction is applied and does not require any adhesive tape or Opsite for sealing.
A circumferential Opsite occlusion seal with T-tail configuration [3] of the suction tube outlet is applied only at the end (s) of the wound. Once suction is applied, the shrinkage of the sponge beneath the glove can be appreciated over the glove. Surgical glove fits well to the hand and also the fingers of the surgical glove can be cut and applied for isolated finger injuries.
A gynaecological glove can be cut obliquely to obtain a greater circumference, which is similar to the cheatle slit in right hemicolectomy.
An intermittent vacuum is applied for 20 minutes of every hour at a negative pressure of 125 mm Hg.
To reduce maceration over the plantar region, the surface is covered by collagen, glycerine magnesium sulphate, or zinc oxide. A 12-hour to 24-hour gap between changing vacuum dressings has been observed to decrease maceration.
DISCUSSION
In attempts to use vacuum-assisted wound healing at the extremities, covering most of the wound area by an inexpensive surgical or gynaecological glove rather than Opsite significantly reduces the cost of each dressing. More sterile surgical and gynaecological gloves are readily available for this purpose. Opsite is used judiciously like a bottle cork to create a seal and cuff the ends of the glove vacuum unit. The surgical or gynaecological glove can be applied to the arms, legs, digits, and foot but is difficult for the adult thighs. The presence of external (Figs. 2-6) fixators would stretch the glove too much. Designing or altering sterile gloves or latex stockings for the purpose of vacuum dressing according to the need and contour of the site would further simplify the dressing In addition, the time required for each vacuum dressing application can be reduced. The efficacy of this modified surgical glove vacuum dressing should be compared to conventional vacuum dressings in further studies. In this series, the results were very effective.
Intussuscepting glove arms with end Opsite cuffs
For lengthy wounds, multiple gynaecological gloves can be cut and applied in a sequential overlapping manner.

(C) Glove vacuum was applied for 15 dressings and exposed bone was completely covered by granulation tissue. Later skin grafting was performed.
