Spider Bite Wound Care and Review of Traditional and Advanced Treatment Options
Background: Approaches to chronic wound care are worlds apart: In developing nations, the care of chronic wounds often involves traditional management with local products (eg, honey, boiled potato peels, aloe vera gel, banana leaves); whereas in developed nations, more expensive and technologically advanced products are available (eg, wound vacuum, saline wound chamber, hyperbaric oxygen therapy, antibacterial foam). The cost for wound care plays a significant role in total health care costs, and that cost is expected to rise dramatically.
Case Presentation: A healthy, 60-year-old man presented after being bitten by a spider 6 days earlier. He was treated and prescribed clindamycin 300 mg 4 times daily for 14 days. Despite treatment, the wound continued to enlarge, and the patient showed symptoms of septicemia. The patient was admitted to the hospital and remained for 3 days. On discharge the patient was given a prescription for doxycycline 100 mg twice a day for 10 days and instructed to use iodoform gauze to pack the wound during daily dressing changes. However, the gauze was ineffective. The patient’s dressing was switched to an antibacterial foam dressing impregnated with gentian violet and methylene blue.
Conclusions: There is a disparity in available wound care product availability. Modern products may yield faster healing times with fewer adverse effects than traditional products. Products used by local healers can produce satisfactory results when more modern products are unavailable and at a fraction of the cost.
Separate studies in 2011 and 2010 from Fukuda and colleagues and Majtan and colleagues, respectively, reported that honey eliminates pathogens from wounds, augments correct moisture balance, and elevates cytokine activity.8,9 Additional studies in 2006, 2008, and 2014 by Henriques and colleagues, Van den Berg and colleagues, and Majtan suggested that honey reduces reactive oxygen species, is responsible for direct antimicrobial effects in a healing wound, inhibits free radical production, and promotes antitumor activity, respectively.10-12 Van den Berg and colleagues suggested that buckwheat honey is the most effective honey in reducing reactive oxygen species.11
Sterile banana leaves. In medically underserved and rural areas, boiled banana leaves are used to treat burns and nonhealing wounds. In a 2015 study, Waffa and Hayah compared gauze dressings with sterile banana leaves wound dressing in patients with partial thickness burns. Topical antibiotics were added to each type of dressing. The results suggested that the banana leaf dressings were easier to remove, patients reported less pain overall, less pain with dressing changes, and demonstrated a decreased time to healing when contrasted with gauze.13 In 2003, Gore and Akolekar compared autoclaved banana leaves with boiled potato peels in the treatment of patients with partial thickness burns. The time to epithelialization, eschar formation, and skin graft healing were equal in both groups. However, banana leaves were 11 times cheaper and rated easier to prepare than boiled potato peels.14 In a study comparing petroleum gauze with sterile banana leaves, Chendake and colleagues reported that in measures of overall pain and trauma during dressing changes, patients with contused and sutured wounds on the face and neck achieved better outcomes with boiled banana leaves compared with petroleum gauze.15
Boiled potato peels. This treatment is used in rural areas of the world as an adjunct for wound care. In 2015, Manjunath and colleagues theorized that the use of boiled potato peels in patients with necrotizing fasciitis decreased the acidic environment created by the bacteria. Additionally, the study asserted that the toxic wound environment created by the bacteria was neutralized by the potassium content in the peel, and the flavonoids in the peel acted as a free radical scavenger.16 In 2011, Panda and colleagues, using povidone-iodine as a baseline control, reported that peel extract and a peel bandage of sweet potato showed an increased wound closure percentage measured by enhanced epithelialization.17 This increased epithelialization was attributed to the antioxidant effect of the peels enhancing collagen synthesis.17
In contrast, in 1996, a study by Subrahmanyam compared autoclaved potato peel bandages with honey dressings as adjuncts in burn patients with < 40% of the total body surface area affected. The author reported that 90% of the wounds treated with honey were sterile in 7 days, while infection persisted in the potato peel group after 7 days. In the same study, 100% of the wounds treated with honey were healed in 15 days vs 50% in the potato peel group.18 In 1990, Keswani and colleagues compared boiled potato peels with plain gauze as adjuncts in the treatment of burn patients and concluded that although the potato peels had no antibacterial effect, the wounds in both groups had identical bacterial species. But the wounds treated with the potato peels showed reduced desiccation, permitting the survival of skin cells, and enhanced epithelial regeneration.19
