The effect of an antimicrobial drain sponge dressing on specific bacterial isolates at tracheostomy sites.

Patients with tracheostomies frequently experience complications, including bacteremia, sepsis, pneumonia, and multi antibiotic-resistant bacterial infections. A prospective, descriptive, randomized, controlled, clinical case series involving seven men and three women was conducted on patients in the neuroscience unit of a long-term rehabilitation hospital during a period of 25 days to compare the use of an nonwoven drain sponge dressing containing an antimicrobial (polyhexamethylene biguanide) to a non-impregnated, nonwoven drain sponge dressing on tracheostomy sites. Specifically, the purpose of the study was to compare the presence of four bacterial pathogens (methicillin-resistant Staphylococcus aureus, Enterobacter cloacae, Pseudomonas aeruginosa, and Staphylococcus aureus) and resident normal skin flora (alpha-hemolytic Streptococci and Staphylococcus epidermidis) at the tracheostomy sites. Culture results for total days of growth showed an absence of pathogens and presence of normal skin flora for 11 study days in patients randomized to the antimicrobial dressing group and an absence of pathogens and presence of normal skin flora for six study days in patients randomized to the control group. The results of this descriptive case series suggest that an antimicrobial drain sponge dressing could be an important adjunct in the control of infections in patients with tracheostomies without compromising normal skin flora.

Polyethylene oxide gel: a new dressing after endoscopic sinus surgery.

The purpose of dressings after endoscopic sinus surgery is to absorb secretions, tamponade bleeding, discourage adhesions, and facilitate sinus and nasal hygiene. The ideal dressing should conform to the irregularities of the nasal-sinus cavity and resist adherence to the wounds so it can be easily removed. It should be economical, non-irritating, and antiseptic. The failure of previous dressings to fulfill all of these criteria led the author to evaluate a new alternative. Polyethylene oxide gel (Vigilon) was identified as a potential improvement and investigated in a clinical trial of 60 cases. This paper presents the author's observations and technique for application. Polyethylene oxide gel resulted in no significant complications. It appears superior to previously described dressings, primarily because of patient comfort at removal.

Comparison of the effects of selected dressings on the healing of standardized abrasions.

OBJECTIVE: To find out which type of dressing (semipermeable film, hydrocolloid, conventional method, or no dressing) allowed abrasions to heal in the least amount of time and had the greatest decrease in wound area. DESIGN AND SETTING: A 4 x 9 factorial was used for this study. There were two independent variables with four levels and two dependent variables. Research was performed at the Athletic Training Research Laboratory at Indiana State University. SUBJECTS: Fourteen subjects (eight males, six females), ages 23 to 34 years, participated in this study. MEASUREMENTS: From daily photographs, the day the wounds were healed was determined. The photographs were also used to measure wound area on the first and last days of the study. Subjects received four treatments (dressings and control), and placement of the dressings was determined by random assignment. RESULTS: Data were analyzed using a repeated-measures multivariate analysis of variance to determine if differences existed among treatment groups for healing time and change in area. Student-Newman-Keuls post hoc testing was performed to determine specifically where the differences occurred. Our results indicate that healing time is affected by covering the wound, and area is decreased by using DuoDerm or Bioclusive. CONCLUSIONS: Bioclusive should be used in the athletic training setting. Bioclusive and DuoDerm are equally effective, but Bioclusive is less expensive. Bioclusive is more expensive than Coverlet, but it is also more effective in reducing the area of the wound.

A prospective, open-label study to assess the clinical performance of a foam dressing in the management of chronic wounds.

Polyurethane foam dressings are used to help absorb wound exudate while maintaining a moist wound environment. To assess the clinical performance of a foam dressing, a prospective, open-label evaluation of 57 outpatients (mean age 69 years) with delayed/non-healing wounds (one per patient, average duration 1.4 +/- 4.1 years) of different etiologies was conducted in 15 medical centers in Germany. Physicians assessed the clinical appearance of the wound bed, periwound skin, and exudate level at the beginning and final evaluation and dressing performance characteristics were rated. Patients were asked to assess their wound pain as none, mild, moderate, or strong. After three dressing changes (performed approximately 3 days apart), slough and necrotic tissue on the wound surface changed from an average of 54% (+/- 33%) to 29% (+/- 25%). At baseline, granulation tissue covered an average of 41% (+/- 31%) of the wound bed compared to 59% (+/- 24%) at the final assessment and the proportion of wounds assessed as heavily exudating decreased from 32% to 11%. During the evaluation, the proportion of patients without periwound skin problems increased from 49% to 66% and the percentage of patients with wound pain decreased from 45% to 26%. Between 80% and 90% of the participating physicians rated the product attributes assessed as "very good" or "good."

[Study on the volume flows through polymeric membranous dressing with silver ions].

The volume flows through double-layer polymeric membranous dressing, formed by three types of theromoplastic polymeric fibers called Textus Bioactive were studied. The first layer contains two types of fibers: the polymeric fibers containing hydrophobic core and hydrophilic surfaces with silver zeolite and hydrophilic super absorbing polymers (SAP). The second layer of membrane contains third type of polymeric fibers, arranged parallel to surface's skin, creating a net, which prevents membranous dressing from sticking to treated wound. The pressure characteristics of the volume flux were determined and it was stated that the value of this flux is dependent on the value of hydrostatic pressure difference (deltaP) and the concentration difference (deltaC) of solutions separated by membrane. Experimental results show that the membranous dressing Textus Bioactive posses the rectifying properties with reference to volume flows. These properties occurs above a threshold value of deltaC. Using the Kedem-Katchalsky equations, the model of the volume flows through membranous dressing Textus Bioactive was made.

[Dressing and wound care pain].

Wound care is an important step for promoting wound healing. Nevertheless it is also a major source of pain for patients with wounds. The results of a survey showed that not only burn patients but also non-burn ones suffered from wound care pain which occurred in inpatients and outpatients. One of the significant factors causing wound care pain was that the dressing adhered to the wound bed. Although some agencies claimed that particular dressings with low adhesion can result in painless removal, the actual effects needed to be verified. Results of clinical trials revealed that for relieving wound care pain of certain kinds of wound, it was recommended to use particular dressings, such as banana leaf dressing, boiled potato peel bandage, Acticoat, Mepital or Mefix.

Evaluation of an alginate dressing for pressure ulcers.

Pressure ulcers that secrete moderate to large amounts of fluid often cause leakage from under dressings, odor, staining of clothing, denuding of the skin, and pain. Two highly absorbent dressings derived from seaweed have been introduced into the U.S. market for use in the management of exuding wounds. Severely debilitated patients with full-thickness pressure ulcers were treated for one week to three months with one of these alginate dressings (Kaltostat). The handling and performance characteristics of the dressing are discussed.

A new high water vapor permeable polyetherurethane film dressing.

This study summarizes the Ph.D.-research project concerning the development of a new high water vapor permeable wound dressing. The dressing is composed of a 15 microns thin polyetherurethane (PEU) film, which has many non-interconnected cavities to enable a high water vapor permeability up to 20.1 g.m-2.h-1.kPa-1. Since only water vapor permeates through the PEU dressing, the wound exudate underneath is condensed into a gelatinous coagulum. Epithelialization was accelerated by 25% under the clot-permissive PEU film compared with the fluid retaining OpSite film. In clinical situations on donor sites and grafted full-thickness burn wounds, the PEU film indeed prevented fluid accumulation and induced the formation of a "red" coagulum underneath. It furthermore reduces pain significantly compared to conventional paraffin gauze dressing. In conclusion, the optimum environment for epithelialization is a wound, in which the exudate is permitted to gelatinize between moist and dry.

Independent dressing after spinal cord injury: a functional time evaluation.

Functional skill independence is generally defined as the ability to perform a functional task. The time required for completion, however, is usually not a major consideration. Postdischarge follow-up interviews indicated that patients do not always continue to perform all reacquired functional skills that were considered important rehabilitation goals. A pilot study was done to look at the skill of dressing independently to determine if time was a factor in the decision to retain, modify, or completely delegate this activity. Ten patients with C6-level quadriplegia, who were capable of self-dressing at discharge, participated in the study. They were timed for dressing at home. Although all ten patients were capable of dressing independently within one hour, none did so routinely. "Too much time and too much work" were the reasons stated. The implication is that a functional skill must be accomplished within the individual's concept of an appropriate time and/or energy framework in order to be considered truly functional.

Whitehead's varnish and Jelonet--a better dressing for skin graft donor sites than Jelonet alone.

Two methods of skin autograft donor site management were evaluated in 40 patients in a prospective randomised double-blind clinical trial. Donor sites were dressed using either a standard dressing of Jelonet, gauze, wool and a crêpe bandage or Jelonet, Whitehead's varnish (compound iodoform paint BPC), gauze, wool and a crêpe bandage. Donor site pain was assessed daily using a linear analogue scale, and the healing time of the donor area was recorded. Whitehead's varnish significantly reduced donor site pain compared to the standard dressing (P = 0.0006). Although overall healing time was not statistically different in the two groups, larger donor sites treated with Jelonet and Whitehead's varnish healed more quickly than those treated with the standard dressing alone.

Accelerated healing of carbon dioxide laser burns in rats treated with composite polyurethane dressings.

Healing time, infection rate, and residual scar formation were compared in carbon dioxide laser burns in rats treated in four ways: Spandra composite dressing, OpSite composite dressing, Petrolatum Gauze (USP), and no treatment. There were no infections and no differences in scar formation among the treatment groups. The mean healing times were ten days for the polyurethane dressings (Spandra and OpSite), 13 days for Petrolatum Gauze, and 16 days for the untreated group. Spandra was easier to apply and handle than OpSite. These findings suggest that synthetic gas-permeable dressings promote healing after cutaneous carbon dioxide laser surgery more effectively than conventional treatments of ointment-impregnated gauze or leaving the wound exposed to the air.

Porous removable rigid dressing for complicated below-knee amputation stumps.

For management of complicated below-knee amputation stumps, a porous removable rigid dressing has been fabricated that can be suspended with a supracondylar cuff or with a waist belt. In addition to permitting frequent observation, eliminating the need for elastic stump bandaging, and maintaining the advantage of the conventional rigid dressing of soft-tissue immobilization to reduce the pain and prevent trauma to the stump, the porous removable rigid dressing facilitates edema reduction and wound healing, prevents moisture building, permits frequent change of dressings and promotes fast stump shrinkage.

Delivery of the topical antimicrobial agents silver sulfadiazine, gentamicin and nystatin to infected burn wounds in rats from preloaded synthetic dressings.

1. A synthetic burn dressing made from polyethylene glycol - 400 (PEG) and poly-2-hydroxyethyl methacrylate (PHEMA) can be prepared to contain topical antimicrobial agents. 2. Sheets of these antimicrobial loaded dressings may be applied to the wounds or alternatively, the synthetic dressing incorporating the active drugs may be formed directly on the burn wound from the PEG-PHEMA drug mixture. 3. The antimicrobials (silver sulfadiazine, gentamicin and nystatin) are continuously and effectively released from the solid dressing over 2-11 days.

[Potentials of a scanning electron microscopic method in studying dressing materials].

The possibilities of the scanning electron microscopy (SEM) technique were evaluated in the studies of functional properties of dressing materials. It was shown that the use of SEM enables the disclosing of the effect of structural characteristics of the dressing materials on their atraumaticity, the appraisal of the absorption capacity of the dressings, and the exploration of the time course of wound healing under the dressings.

[Use of tissue adhesives and collagen dressings in wedge-like and transverse kidney resection in rabbits].

In cuneiform and transversal inferior renal pole resection in 64 rabbits either surgical spray adhesive "Chirurcoll-Polfa" or adhesive-collagenous dressing was applied to the parenchyma. Morphological examinations were performed 14 days and 1, 3 and 6 months after the operation. The adhesive-collagenous dressing was found to be the best method of wound dressing to cover the surface after transversal renal pole resection. The technique of adhesive-collagenous dressing was more useful compared to the use of adhesive alone. The adhesive-collagenous bandage assures better wound tightness with smaller adhesive amount than in exclusive adhesive application and causes less adhesions which almost always develops after the spray adhesive application.

Fluid handling properties of hydrogel dressings.

The fluid handling properties of four hydrogel dressings were examined in a laboratory-based study to determine their ability to absorb liquid from or donate liquid to a range of standard test substrates simulating wound tissue in various states of hydration. The tests suggest that three of the dressings are likely to be effective fluid-donating agents, and one of the dressings has a dual ability to donate or absorb liquid depending upon moisture content and nature of the substrate to which it is applied. These observations are discussed in the context of the clinical use of hydrogel dressings.

[In vitro and in vivo studies of a temporary absorbable dressing].

The major advantage of biodegradable synthetic wound dressings compared to other synthetic materials and biological tissue derivatives is avoidance of the necessity to change the dressing. The copolymer films used in this study were made of lactic and caproic acid. They pose no problems concerning immunology or transmission of diseases. Moreover, the substances released by degradation may possibly influence the process of wound healing. The material proved to be non-toxic and was used successfully as a carrier for cell culture with keratinocytes. The permeability for bacteria is determined by degradation. Evaluation of the bacteriological studies indicates secure protection against secondary contamination of the films for at least 15 days, however. Concerning application, dressing properties, wound healing and wound retraction, no disadvantages were found in comparison with the results of the competition's film Opsite. Based on these findings, the films are now used in a clinical study as a wound dressing for split-skin donor sites.
