A new porous cohesive support bandage.

A new support bandage has been developed that is cohesive, sticking only to itself without adhering to the skin. It is warpknit product, impregnated with an acrylic compound, that consists of individual panels connected by a hinge stitch. It exhibits moderate extensibility under low loads which allows the health professional to apply the bandage so that it gives firm support to the underlying tissue without constriction. Its macroporous structure permits sufficient water vapor transmission to allow the underlying skin and/or wound to remain dry.

The effect of a collagen bandage lens on corneal wound healing: a preliminary report.

Collagen bandage lenses were inserted in 24 eyes of white New Zealand rabbits following 8-incision radial keratotomy. Specimens were examined at eight and 24 hours by light and electron microscopy. Treated eyes demonstrated more complete epithelial healing, as evidenced by surface microvilli and differentiation into multi-layers. In the treated eyes there was reduced stromal edema at the wound site, and reactive keratocytes were limited to the wound margins. Collagen bandage lenses therefore may be useful in the treatment of a variety of ocular surface problems.

Bandage-induced nail disorders.

It can be helpful at times to bandage around fingernails but constant bandaging can produce excess maceration. Chronic paronychia can be induced by the excess wetness. Other disorders that occur because of maceration are reviewed.

[Indications for bandaging of the legs].

Study of the literature on the prevention of deep vein thrombosis shows the inefficacy of calf bandaging in the ambulation phase. Since thrombosis starts soon after or during operation, prophylactic measures are successful only if performed from the beginning of hospitalization. Orthostatic disturbances are not a general problem in the mobilization phase, as is shown in a study on 20 patients after myocardial infarction or heart surgery in whom leg compression did not influence circulatory regulation. In chronic venous or lymphatic insufficiency, however, compression therapy is of proven value. Such patients should be identified and treated. On the other hand, leg bandaging as a general preventive measure in the mobilization phase is no longer justified, but is indicated in individual patients with venous or orthostatic problems.

Hydrophilic bandages in penetrating keratoplasty.

A retrospective analysis was conducted of 100 consecutive cases of penetrating keratoplasty revealing that in 68% of the cases hydrophilic bandage lenses were applied at some time during the course of the operative procedure or postoperatively. In 4% of the cases, lenses were applied before the actual start of keratoplasty and in 13% the lenses were applied before the conclusion of the operative procedure. In 28%, the initial lens application occurred within the first 10 postoperative days while in 18% initial application occurred prior to the time of suture removal. In the remaining 5% of the cases, the lens was applied relatively late in the postoperative course. Primary indications for bandage lens application were prophylactic in cases of infants, chemical burns, exposure, and dry eyes. Therapeutic indications included surface drying and erosion, wound margin defects, patient discomfort, and inflammatory episodes.

Should Esmarch bandages be used for exsanguination in knee arthroscopy and knee replacement surgery? A prospective trial of Esmarch exsanguination versus simple elevation.

In order to compare the adequacy of exsanguination produced by Esmarch bandages with that produced by simple elevation for 2 min, a blind randomized prospective trial was undertaken in 50 patients undergoing total knee replacement surgery and 50 patients undergoing knee arthroscopy surgery. The mean blood loss during total knee replacement was significantly greater in the group exsanguinated by elevation (P < 0.01). The haematocrit of samples of the arthroscopy drainage fluid was consistently less than 1%, irrespective of the method of exsanguination used. None of the operating surgeons reported that they considered that either knee replacement surgery or arthroscopic knee surgery had been made any more difficult by the use of elevation as a means of exsanguination. In view of the established risks of using Esmarch bandages, we would suggest that the use of this method of exsanguination in these fields of orthopaedic surgery is not justified.

Evaluation of a porous bovine collagen membrane bandage for management of wounds in horses.

OBJECTIVE: To evaluate the effect of a porous bovine-derived collagen membrane (PBCM) on the rates of wound healing, cellular events, presence of granulation tissue, and appearance at termination of the study in surgically created full-thickness cutaneous wounds of the distal portion of the extremities of horses. DESIGN: Treated wounds (n = 12) received a PBCM dressing and control wounds were covered with a nonadherent dressing. Forelimbs and hind limbs were cross paired; the right forelimb and left hind limb always received the same dressing application, as did the left forelimb and right hind limb. Limbs pairs were then randomly assigned to 1 of the 2 dressings. ANIMALS: Six healthy male horses (3 sexually intact, 3 geldings) ranging from 2 to 10 (mean, 6.5) years and weighing between 278 and 568 (mean, 408.5) kg were studied. PROCEDURE: Full-thickness skin wounds (6.25 cm2) were created on the dorsal metatarsi and metacarpi of the experimental animals. A preformed PBCM dressing was evaluated in half the wounds (n = 12). Control wounds (n = 12) were dressed with a nonadherent gauze dressing. At each bandage change, wounds were subjectively assessed and were photographed, and measurements of horizontal and vertical wound dimensions were documented. Wound biopsy specimens obtained on days 2, 5, 7, 10, 21, and 31 were evaluated for presence of collagen, fibrin, inflammation, epithelium, and cellular elements of healing. Planar morphometry was used to determine total wound area and granulation area from the wound photographs. Percentage of contraction and epithelialization were calculated from these values. Linear regression analysis of the square root of the total wound area and the granulation area was performed. Wound area measurements were analyzed, using ANOVA for repeated measures. Regressions were compared, using covariance analysis and ANOVA. Significance was considered at P < 0.05. RESULTS: Fibrin score, neutrophil score, and degree of inflammation were significantly greater in the PBCM-treated wounds. No significant differences in the total wound, epithelialized, or contraction areas were detected between the PBCM-treated and control (nonadherent-treated) wounds. Rates of wound healing were not statistically different between the 2 treatment groups, though they were significantly slower in the hind limbs, compared with the forelimbs. Scabs were formed more frequently in the PBCM-treated wounds. CONCLUSIONS: Application of a porous collagen bandage was not detrimental to full-thickness cutaneous wound healing in horses.

Compression bandaging for venous leg ulcers.

Effective compression heals leg ulcers and prevents their recurrence. Incorrect bandaging and poor technique are often features of leg ulcer management. A number of bandage systems are currently in use. Multi-layer systems appear to be more effective than single-layer systems.

Use of a four-layer bandage system in the treatment of an i.v. drug abuser with chronic upper extremity ulcerations: a case study.

A patient with a ten-year history of heroin abuse presented to a wound healing clinic for treatment of multiple ulcerations to his upper arm. The largest measured 3.5 cm x 1.7 cm. The patient related that these wounds came from his i.v. heroin use. Previous treatments included iodine packed gauze, saline soaked fine mesh gauze, dakins solution, and wet-to-dry dressings; all treatments were unsuccessful. Treatment included cleansing the wound with normal saline, packing the ulcers with a calcium alginate rope, and wrapping the arm using a four-layer bandage. The dressing remained in place for 7-day time intervals. During the course of treatment, the patient remained heroin-free. No unscheduled dressing changes occurred, nor did the patient report discomfort with the dressing or during dressing changes. The patient was able to maintain complete range of motion throughout care. Complete healing was noted by day 42. The calcium alginate dressing combined with the 4-layer bandage system has proved successful in treating the patient.

Pneumatonometry through bandage contact lenses.

Bandage soft contact lenses are an effective therapy for patients with a variety of corneal diseases. These patients often require accurate measurement of the intraocular pressure, necessitating movement or removal of the contact lens for slit-lamp Goldmann applanation tonometry. Intraocular pressure was measured in 21 normal, healthy volunteers, using a pneumatonometer (Alcon). A therapeutic soft contact lens (Plano T) was then placed on the eye and the pneumatonometer was used to remeasure the intraocular pressure through the contact lens. The average intraocular pressure without the contact lens was not statistically different from the intraocular pressure with the contact lens. These data suggest that pneumatonometry is an effective way to assess the intraocular pressure in patients wearing bandage contact lenses, thus eliminating the need to manipulate the lens solely for the purpose of intraocular pressure determination.

Distal arterial reconstruction using Esmarch's bandage technique to salvage upper extremity function in thoracic outlet syndrome caused by cervical ribs: a report of two cases.

We present herein the cases of two patients with thoracic outlet syndrome (TOS) who required arterial reconstruction due to gangrene of the fingers and/or hand. In both patients, the cervical ribs had produced intimal injury of the subclavian arteries, and the successive distal arterial embolism brought about severe ischemia of the affected upper extremity. To treat the TOS, the cervical ribs were resected through a supraclavicular incision. In the first patient, arterial reconstruction was performed from the subclavian artery to the radial collateral artery, a branch of the deep brachial artery, which resulted in minimizing amputation of the gangrenous hand. In the second patient, resection and direct anastomosis of the injured subclavian artery were performed, and bypass surgery from a brachial artery to an interosseous artery was carried out, preserving finger function. Reversed saphenous vein grafts were utilized and Esmarch's bandage technique was applied as a substitute for a vascular clamp in both patients. Following these case reports, we discuss the technique of performing distal bypass in the upper extremities and comment on the usefulness of Esmarch's bandage technique for preserving upper extremity function.

Tono-Pen estimation of intraocular pressure through bandage contact lenses.

The Tono-Pen was used to determine the reliability of intraocular pressure readings obtained through bandage contact lenses in 48 eyes of 24 healthy volunteers. The mean difference between readings obtained before lens insertion and readings obtained with the lens in place was 0.27 mm Hg and was not statistically significant (P greater than .2). The mean difference between readings obtained with the lens in place and readings obtained after lens removal was 0.85 mm Hg and was statistically significant (P less than .01). Ninety-five percent confidence intervals suggest that the true difference between mean Tono-Pen readings obtained with and without the lens in place ranges from -0.3 to +1.5 mm Hg. Our results suggest that the Tono-Pen is probably an effective way to estimate intraocular pressure through bandage contact lenses, with a probable true mean difference of less than 1.5 mm Hg and a standard deviation of about 2 mm Hg.

Sustained gentamicin release by presoaked medicated bandage contact lenses.

Current therapeutic regimens for external ocular infections require instillation of antibiotics up to every quarter of an hour in concentrations higher than those commercially available. As an alternative to topically applied gentamicin eye drops, the possibility of sustained gentamicin release by bandage contact lenses was investigated. Ten hydrogel bandage contact lenses (61.4% HEMA and 38.6% water content) were soaked overnight in a 0.5% solution of sterile, unpreserved, commercially available gentamicin, and fitted thereafter on ten eyes of healthy adult volunteers. Gentamicin concentrations in the tear film were determined 10, 30, and 60 minutes, and 4, 8, 24, 48, 72, and 96 hours after fitting, using agar diffusion bioassay. Bactericidal concentrations (greater than 1.6 micrograms/ml) were found up to 3 days after contact lens fitting in all subjects. No toxic topical or systemic effects were seen.

[Therapeutic hydrophilic bandage lenses after perforating keratoplasty in severe eye chemical burns].

BACKGROUND: The prognosis of penetrating keratoplasty after severe eye burns is uncertain. Beside of immune reactions the outcome is determined by surface problems. PATIENTS AND METHODS: Between July 1991 and October 1993 in 15 patients (16 eyes) with grade IV eye burns penetrating keratoplasties with large diameters (11-16 mm) were carried out. Cultured corneas were used with an intact epithelium. In 9 eyes hydrophilic bandage lenses (Geaflex 70, Fa. Wöhlk, Kiel) were applied initially, in the remainder 7 eyes within 7 days postoperatively. RESULTS: The lens radius best suited was found out by trial, because corneal topography was not possible for many weeks. In 12 (75%) eyes the lens had to be fitted steep, with a radius from < or = 8.7. A change in lens radius during the healing course was rare. The frequent use of artificial tear drops was important, because many eyes showed clinical manifestations of dry eye syndrome. Complications during soft contact lens wearing were rare. In 5 eyes microbiological examination was positive, but successfully treated. Under the protection of soft contact lenses 9 eyes maintained an intact epithelium. In the remainder eyes severe vascularisation with large persistent epithelial defects occurred mostly as a consequence of immune reactions. These keratoplasties developed on growth of inflammatory pannus or progressive ulceration. The average of the follow-up time was 22 months. CONCLUSION: The use of large diameter keratoplasties in combination with hydrophilic bandage lenses proved to be successful to maintain the integrity of the epithelium in these high-risk keratoplasties. The prognosis of these transplants is, however, determined by immune reactions.

Rosin (colophony) and zinc oxide in adhesive bandages. An appropriate combination for rosin-sensitive patients?

Adhesives and bandages containing zinc oxide (ZnO) and rosin are often used for treatment of ulcers. The aim of this work was to study a possible inhibitory effect of ZnO on the elicitation of allergic contact reactions to rosin and to determine whether such an effect might be due to the formation of zinc resinates. Patch testing in rosin-sensitive patients was performed with mixes of ZnO and rosin. The eliciting capacities of one mix in which zinc resinates might be formed and another mix in which the formation of zinc resinates was prevented, were compared to the eliciting capacity of rosin alone. If a reduction of the allergic response was observed for the mix in which zinc resinates might form and if no reduction was observed for the mix in which formation of zinc resinates was prevented, this would support the hypothesis that the reduction in eliciting capacity was due to formation of zinc resinates. However, we could not see any difference in eliciting capacity when comparing the 2 mixes with a test preparation of rosin. Commercial adhesives (bandages) containing ZnO and rosin were patch tested in 7 rosin-sensitive patients. The concentration of abietic acid in the adhesives was determined with HPLC. Abietic acid was detected in all but one of those declared to contain rosin. The patients reacted to the adhesives in which abietic acid was detected. For rosin-sensitive persons, the addition of ZnO to rosin-containing adhesives cannot be regarded as an appropriate measure to inhibit the elicitation of allergic reactions.

Post-keratoplasty corneal ulcers and bandage lenses.

285 cases of penetrating keratoplasty in whom hydrophilic bandage lenses were fitted were analyzed for the occurrence of corneal ulcers. Of these eyes 26 developed culture-proven bacterial ulcers. No correlation could be made between any particular type of contact lens and the development of corneal ulcer. Although no single factor could be delineated which may be responsible for this problem, this risk appears to be escalated where host defense mechanisms are impaired. The clinician should recognize the potential risk in using bandage lenses when the cornea is immunosuppressed and completely denervated.
