Randomized Controlled Trial
The effect of virtual reality on pain and range of motion in adults with burn injuries.
Few studies have empirically investigated the effects of immersive virtual reality (VR) on postburn physical therapy pain control and range of motion (ROM). We performed a prospective, randomized controlled study of the effects of adding VR to standard therapy in adults receiving active-assisted ROM physical therapy, by assessing pain scores and maximal joint ROM immediately before and after therapy on two consecutive days. Thirty-nine inpatients, aged 21 to 57 years (mean 35 years), with a mean TBSA burn of 18% (range, 3-60%) were studied using a within-subject, crossover design. ⋯ Ninety-seven percent of patients reported zero to mild nausea after the VR session. Immersive VR effectively reduced pain and did not impair ROM during postburn physical therapy. VR is easily used in the hospital setting and offers a safe, nonpharmacologic adjunctive analgesic treatment.

Multicenter Study
The effect of burn center and burn center volume on the mortality of burned adults--an analysis of the data in the National Burn Repository.
Regional variations of care, and improved outcomes with larger volumes, have been well described in the medical and surgical literature for a variety of conditions including heart surgery, vascular surgery, and orthopedic surgery. Burn care has not been recently subjected to such an analysis. The National Burn Repository (NBR) contains de-identified patient and burn center data to allow this analysis. ⋯ Mortality does not linearly improve with burn center volume and plateaus with increasing burn center size. The optimal burn center size is a complicated and contentious question. Future discussions about burn center size and density should incorporate not only mortality but also the region's ability to absorb surges in volume, and the optimal "staffing" ratios for the multidisciplinary aspects of burn care.

A lack of noninvasive tools to quantify edema has limited our understanding of burn wound edema pathophysiology in a clinical setting. Near-infrared spectroscopy (NIR) is a new noninvasive tool able to measure water concentration/edema in tissue. The purpose of this study was to determine whether NIR could detect water concentration changes or edema formation in acute partial-thickness burn injuries. ⋯ At 48 hours, deep partial-thickness injuries showed a 23% increase in water content compared with 18% superficial partial-thickness burns. NIR could detect differences in water content or edema formation in partial-thickness burns and unburned healthy regions. NIR holds promise as a noninvasive, portable clinical tool to quantify water content or edema in burn wounds.

Comparative Study
Healing of mid-dermal burns in a diabetic porcine model.
Wound healing is delayed in diabetic patients. We developed a diabetic-porcine burn model and compared the healing of partial-thickness burns in normal and diabetic pigs. We hypothesized that wound healing would be delayed in the diabetic swine. ⋯ All burns were completely reepithelialized at 21 days, and none of the wounds were infected. Reepithelialization of partial-thickness burns is delayed in streptozotocin-induced diabetic pigs when compared with normal pigs. It is unclear whether the delay in healing is due to the thinner skin or the metabolic consequences of diabetes or their combination.

This study tested the hypothesis that very young children who received more morphine for acute burns would have larger decreases in posttraumatic symptoms 3 to 6 months later. This has never before been studied in very young children, despite the high frequency of burns and trauma in this age group. Seventy 12- to 48-month-old nonvented children with acute burns admitted to a major pediatric burn center and their parents participated. ⋯ The correlation between morphine dose and amount of decrease in symptoms on the arousal cluster of the CSDC was significant (r = -0.63, P < .05). Findings from the current study suggest that, for young children, management of pain with higher doses of morphine may be associated with a decreasing number of posttraumatic stress disorder symptoms, especially those of arousal, in the months after major trauma. This extends, with very young children, the previous findings with 6- to 16-year olds.
