Abstract

Description

TWO-PART DRESSING SUITABLE FOR USE IN SURGERY Field of the Invention
This invention relates to a product for use in surgery, and in particular to a film that can be used for skin sterilisation. Background of the Invention
It has been estimated that up to 55% of patients in US ICU are infected with methicillin-resistant S. aureus (M1RSA). The UK Health Protection Agency has reported that, in 2000, the rate of S. aureus bacteremias was 1634 per 100,000 people and that, of these, between 34 and 49% were methicillin-resistant. The risk of MRSA infection in hospitals is exaggerated by poor sterilisation techniques.
Currently, skin sterilisation is typically a two-part process. Many surgeons instruct patients to shower with antiseptic soap prior to the procedure. Once in theatre, sterilisation is via chlorhexidine or povidone iodine or isopropyl alcohol (in procedures without electrocauterisation). Povidone iodine should be allowed to dry, but this often does not happen.
Summary of the Invention
The present invention is based on the realisation that the use of a simple product can provide effective sterilisation prior to surgery, without the disadvantages of procedures described above, and can indeed be helpful to the surgeon, in locating the point of incision. According to the present invention, such a product (preferably an adhesive dressing, carries on one face a gel or semi-solid comprising an antimicrobial compound. Such a dressing is applied to the locus of incision at any suitable time before surgery, and maintains that locus sterile until surgery.
In a broad aspect of the invention, a gel for application to a patient comprises an antimicrobial compound. That compound can provide effective skin sterilisation, and reduce the risk of infection. Description of the Invention
In one embodiment of the present invention, a shaped sterile dressing can be applied pre-operatively, e.g. up to 24 hours before surgery, and which provides a bactericidal compound in situ. The compound may be any effective material, such as a synthetic anti-bacterial agent, but it will often be preferred to use a "natural" chemical product that is more likely to encourage patient uptake; a particularly useful compound of this type is tea tree oil. Other examples are vegetable, carrier, base or essential oils such as lavender, camomile, manuka, rosewood, paperbark, meadowfoam, macadamia nut, sea buckthorn seed, tamanu, quinoa or gotu kola oil. This dressing provides pre-surgical sterilisation and also a surgical guide. This is particularly appropriate for surgeons who make "named" incisions.
A product of the invention, whether a gel, dressing or plaster, may also be made available over the counter, for patients to use before or following surgery or as a form of medicated product.
The backing film for use in the product of the invention makes the patient, nursing staff and surgeon aware of the locus of incision, as well as keeping that locus clean. An additional advantage of using a backing film is that bacteria are immobilised.
Suitable materials, which may be adhesive, include those available as Steridrape and Opsite.
The backing film provides a physical barrier and a sterile zone. It may be removed prior to surgery, so that the relatively large protected zone leaves an agent that kills bacteria in the area of incision.
A relatively small area is covered by a material which is or carries the gel (or hydrogel or hydrocolloid). Such a two-part product is preferred.
For pre-operative use, it is important that the active agent should leach out of the carrier. A gel, hydrogel or hydrocolloid is particularly useful for this purpose. Gel materials in which the active agent can be held, and from which it can be released, are well known. For post-operative use, a product of the invention can act as a healing agent.
A two-part dressing of the invention can be used in various ways. The two parts may be applied at the same time, and then one or other may be removed before surgery. The backing film or "frame" that defines the wound area may be applied first, or the central part (which is used primarily to disinfect the wound area) may be applied before that. The central part may be applied before or after surgery.
The term "frame" is used herein to define an area within which the wound is to be found, and may define an aperture within which the wound is not covered, or it may cover the wound. The surgeon may wish to make an incision through this film.
Either or each of the two parts may comprise adhesive. It is also possible that either or each part may be held in situ by other means, including any semi-solid carrier material. The term "wound" is used herein to define an existing wound or the site of a surgical incision that may be made after application of one or both parts of the two-part dressing.
A product of the invention will typically be packaged in sterile form. The two parts may be provided together or separately. The invention will now be described by way of example only with reference to the accompanying drawing, which is a plan view of a two-part dressing embodying the invention. It is suggested that such a dressing is applied 24 hours before the surgery. It may be removed before surgery takes place. After surgery, the gasket dressing is positioned around the site, and the carrier is left in position. The inner dressing may then be applied. The post-operative dressing may then be removed, leaving a dressing on the skin. A new two-part dressing may then be applied over the original marker, to be left in position; the outer and inner dressing may be applied sequentially, if desired. This treatment may be repeated, if desired.
