Although several studies have investigated models of nerve electrical injury, only a few have focused on electrical injury to peripheral nerves, which is a common and intractable problem in clinical practice. Here, we describe an experimental rat model of peripheral nerve electrical injury and its assessment. ⋯ We presented a model of peripheral nerve electrical injury that avoided the interference of various external factors, such as current instability, compression of the surrounding tissues, and altered blood supply. The model allowed quantitation and ranking of the nerve injury into four degrees. It facilitated effective evaluation of nerve function impairment and repair after injury. It can be used post-surgically to evaluate peripheral nerve impairment and reconstruction and enables translational interpretation of results, which may improve understanding of the mechanisms underlying the progression of peripheral nerve electrical injury.

Burn survivors undergoing complex glycemic derangements in the acute period after burn are at significantly increased risk of worse outcomes. Although most critical care investigations recommend intensive glycemic control to prevent morbidity and mortality, conflicting recommendations exist. To date, no literature review has studied outcomes associated with intensive glucose control in the burn intensive care unit (ICU) population. ⋯ A majority of the studies (6/8) reported higher risk for hypoglycemia with tight glucose control, but few reported instances of adverse sequela associated with hypoglycemia. Intensive glucose control may provide benefit to burn patients, but complications associated with hypoglycemia must be considered. This review recommends an individualized patient-centered approach factoring comorbidities, burn injury characteristics, and risk factors when determining whether to employ intensive glucose control.

Opioid prescription and opioid disorders in burns: A large database analysis from 1990 to 2019.
Opioids remain crucial in the management of burn pain. A comprehensive analysis of opioid use in burns and their complications has not been investigated. ⋯ The risk of opioid-related disorders has nearly doubled since the year 2000 warranting precautions when prescribing pain medications to burn patients.

Patients with extremely severe burns often require rapid wound closure with a tangential excision or escharectomy combined with a skin graft to reduce life-threatening complications such as infection. Traditional tangential excision surgery using the Watson or Humby knife does not allow accurate excision of necrotic tissue and often removes too much active tissue, which is detrimental to the rapid healing of the wound. Importantly, the Versajet hydrosurgical system, with its smaller handle, allows for more precise excision of necrotic burn tissue and preserves more active dermal tissue, positively affecting wound healing and scarring. This study compared the safety and efficacy of hydrosurgical combined with autologous skin grafting to conventional excision combined with autologous skin grafting in patients with extremely severe burn. ⋯ The hydrosurgical debridement group presented with shorter operative time, less blood loss during surgery, faster postoperative nutritional recovery, less postoperative inflammatory response and faster wounds healing, and did not increase the hospitalization cost, postoperative bacterial culture of the wounds and the number of skin grafting surgeries. In patients with extremely severe burn, hydrosurgical debridement combined with autologous skin grafting group is safer and more effective than those in the conventional debridement combined with autologous skin grafting group.
