In Ghana Silver Sulfadiazine (often in the form of Dermazine cream) is easily the most frequently used topical agent for dressing of burn injuries. It is a white, highly insoluble compound that is synthesized from silver nitrate and sodium sulfadiazine [7] [8]. It is available in 1% concentration in a water-soluble cream base. The cream is relatively painless to apply and has an in vitro activity against a wide range of organisms including S. aureus, E. coli, Klebsiella species, Pseudomonas aeruginosa, Proteus species, and Candida albicans [8].

However, there are quite a few downsides to the use of Silver Sulfadiazine. Acute hemolytic anemia has been reported in burn patients treated with silver sulfadiazine who lacked the enzyme glucose-6 phosphatase [9]. The most frequently associated clinical finding is a transient leukopenia that occurs within several days of the initiation of therapy. This is associated with a disproportionate decrease in circulating neutrophils. The incidence is from 5% to 15% of patients treated [10], and it has been proposed that there is a direct toxic effect of silver sulfadiazine on bone marrow. Some of the benefits of this topical agent are its ease of use and its ability to reduce pain. It has some tissue-penetrating ability, but is limited to the surface epidermal layer Thus tissue penetration is poor [11] [12].

Another disadvantage to the use of Silver Sulfadiazine is that the antimicrobial effectiveness has been observed to last for up to 24 hours [8]. This implies that the agent has to be applied on a daily or twice-daily basis. When this is not adhered to the cream becomes a broth, a medium for bacteria culture in the wound.

In our situation dressings are done after every 72 hours. With this regimen, our patients and their relatives have to spend about $300 each week. This is already a huge financial strain on patients and their families. Twice daily dressings will mean $1400 on the average per week for each patient.

Another shortcoming to the use of Silver Sulfadiazine is the possibility that it may retard epithelialization [13].

For these reasons we, in our centre, have stayed away from the use of Silver Sulphadiazine. This in our opinion has resulted in good epithelialization of wounds and have avoided all the problems associated with the use of Silver Sulfadiazine.

Recommendations for the management of burn blisters are varied and range from leaving blisters intact [14], to removing the blistered skin immediately [15], or delaying removal [16]. This lead author recommends leaving burn blisters intact. Blisters form in the stratum spinosum layer of the epidermis. An intact blister usually indicates a superficial partial-thickness wound, which will heal spontaneously within 3 weeks. If, under these circumstances, the blistered skin is removed, the wound is converted from an absolutely painless one to a painful one, this also elicits the metabolic response to trauma [17]. It may further result in an open wound exposed to colonization by bacteria and potential infection [14]. Additionally it is the opinion of this author that that blistered skin serves as a biological dressing of the wound. It is also very rare to have an infection of burn wound with intact blisters. Therefore, this lead author prefers to leave blisters intact, and recommends that they be dressed gingerly protecting the blisters (Figure 1).

Patients who are ambulatory are encouraged to have a supervised shower prior to wound dressing. Bathing in the Bath tub is discouraged as soon as the patient is found to be ambulatory. Though there is no empirical evidence, there is always the possibility that the use of a single bathtub for all the burn patients may lead to cross-infection no matter how conscientious the staff maybe with cleaning and decontamination of the bath in between patients.

In 2003, the International Wound Bed Preparation Advisory Board established an algorithmic approach to wound management with the development of the ‘T.I.M.E.’ acronym [18] [19]. This Identified four components of wound bed preparation, which address the different pathophysiological abnormalities underlying chronic wounds:

1) Tissue management.

2) Inflammation and infection control.

3) Moisture balance.

4) Epithelial (edge) advancement.

The T.I.M.E. framework comprises the comprehensive strategies that can be applied to the management of different types of wounds to maximize the potential for wound healing [20].

Winter’s seminal paper from 1962 showed that a moist wound environment accelerates healing. According to his work wounds heal 50% faster if kept moist (Winter, 1962) [21]. Moist wounds enhance the regrowth of new skin (epithelialisation). Other studies have also shown that a moist wound prevents tissue dehydration and cell death [22].

Our centre employs the use of Vaseline gauze for burn wound dressing. The use of Vaseline gauze is seen as the nearest, easiest and the most cost-effective method of dressing that helps one to achieve the TIME concept.

Vaseline Gauze is a sterile, occlusive dressing consisting of fine-mesh, absorbent gauze impregnated with approximately three times its weight of white petrolatum.

Petrolatum impregnate remains moist to minimize drying out and adherence. It acts by sealing water into the skin.

The non-adherent fine mesh reduces pain and trauma during dressing changes

· The gauze also Conforms to body contours to help seal air leaks and unwanted fluid loss.

· It is generally non-toxic, non-sensitizing and non-irritating.

When using Vaseline the wound will scab less and the new skin will be less raised (or not at all).

Infection is common in burns because the injury causes the skin to lose its natural barrier to microbes; this allows pathogens to have a direct entry route to the wound. Bacteria and fungi are the most common pathogens found in burn wounds; these can originate from the patient’s own skin, gut and respiratory microflora, as well as through contact with the hospital environment or healthcare workers [23] [24].

In addition, burn wounds usually produce high levels of exudate, which creates a suitably moist, nutrient-rich environment for bacterial growth [25] [26] and may result in infection [27]. Infection of burn wounds can delay healing and encourage scarring. Furthermore, without appropriate treatment, an infection may develop into something more serious, such as multi-organ dysfunction syndrome or invasive infections, such as bacteraemia, or sepsis [28]. Data from the French Burns Centres indicates that 19% of inpatients with burns develop an infection [29]. Thus, not all burn patients develop wound infection.

It is difficult to diagnose whether a burn wound is infected or not because the burn injury itself can appear inflamed, which is a symptom of infection. Secondly, the presence of micro-organisms in the wound does not necessarily mean that it is infected. However, sometimes, colonisation can shift to infection: this progression depends on three factors, namely, host immune function, the level of bacterial inoculum and bacterial virulence [30]. According to the guidelines of the French Society for Burn Injuries (SFETB), antibiotics should be administered once an infection has been diagnosed [31]. Thus the advice is that antibiotics should be used only when wound infection is diagnosed in a burn patient.

In our centre antibiotics are initiated on presentation. Intravenous antibiotics (IV Ceftazidime) is routinely used based on work done by the author [32]. Antibiotics are initiated on presentation because most of the burn patients apply topical “first aid” prior to presentation at the hospital. Some of the substances applied to the wounds as “first aid” include, Gentian violet, Ashes from the coal pot, sawdust, toothpaste, seawater, Vaseline petroleum gel, Aloe Vera ointment, milk and egg yolk. Some have even presented to the hospital after applying cow dung as “first aid” (Figure 2).

The burn wound is initially sterile from the heat however the application of these topical substances makes the wound contaminated -most likely leading to infection. Depending on the substances applied as “first aid” antibiotic cover for anaerobes is added (IV Metronidazole).
