Randomized Controlled Trial Comparative Study
Comparison of traditional burn wound mapping with a computerized program.
Accurate burn estimation affects the use of burn resuscitation formulas and treatment strategies, and thus can affect patient outcomes. The objective of this process-improvement project was to compare the accuracy of a computer-based burn mapping program, WoundFlow (WF), with the widely used hand-mapped Lund-Browder (LB) diagram. Manikins with various burn representations (from 1% to more than 60% TBSA) were used for comparison of the WF system and LB diagrams. ⋯ The results of 100 samples, compared using Bland-Altman analysis, showed no difference between the two methods. WF was as accurate as LB mapping for all burn surface areas. WF may be additionally beneficial in that it can track daily progress until complete wound closure, and can automatically calculate burn size, thus decreasing the chances of mathematical errors.

Randomized Controlled Trial
A feasibility study assessing cortical plasticity in chronic neuropathic pain following burn injury.
The aim of this article is to evaluate the neuroplastic changes associated with chronic neuropathic pain following burn injury and modulation feasibility using transcranial direct current stimulation (tDCS). This is a crossover, double-blinded case series involving three patients with chronic neuropathic pain following burn injury. Participants were randomly assigned to undergo single sessions of both sham and active anodal tDCS over the primary motor cortex, contralateral to the most painful site. ⋯ Clinical outcomes did not change after a single session of tDCS. Results are consistent with previous studies showing that patients with chronic neuropathic pain have defective intracortical inhibition. This case series shows early evidence that chronic pain following burn injury may share similar central neural mechanisms, which could be modulated using tDCS.

Randomized Controlled Trial Comparative Study
Ketamine-propofol vs ketamine-dexmedetomidine combinations in pediatric patients undergoing burn dressing changes.
The aim of this study was to compare ketamine-propofol (KP) and ketamine-dexmedetomidine (KD) combinations for deep sedation and analgesia during pediatric burn wound dressing changes. After obtaining approval from the University Ethics Committee, burn wound care or wound dressing changes were performed on 60 American Society of Anesthesiologists physical status I and II inpatients aged between 8 and 60 months with second-degree burns ranging from 5 to 25% TBSA. After recording the demographic data, the heart rate, systolic arterial pressure, diastolic arterial pressure, peripheral oxygen saturation, respiratory rate, and Ramsey sedation scores were recorded for all patients before and during the procedure. ⋯ A significant amount of respiratory depression and hypoxia was observed in group KP but not in KD (P < .05). Both the KP and KD combinations were effective for sedation and analgesia during dressing changes in the pediatric burn patients. The KD combination can be considered as an excellent alternative for pediatric wound dressing changes which does not result in respiratory depression.

Randomized Controlled Trial Comparative Study
A randomized controlled pilot study comparing aqueous cream with a beeswax and herbal oil cream in the provision of relief from postburn pruritus.
Postburn itch is reported to affect up to 87% of the burn population. Although treatments for postburn itch are multimodal, they remain consistently ineffective. However, recent anecdotal evidence from several outpatients at a tertiary referral hospital suggests that a cream combining beeswax and several herbal oils may be effective in the minimization of postburn itch. ⋯ In addition, when managed with beeswax and herbal oil cream, participants found that their itch recurred later (P ≤ .001) and their use of antipruritic medications was lower (P = .023). Findings of this study suggest beeswax and herbal oil cream to be more effective in the minimization of postburn itch than aqueous cream. Given this, a larger study examining the efficacy of beeswax and herbal oil cream appears warranted.

Randomized Controlled Trial Comparative Study
Double-blind, randomized, pilot study assessing the resolution of postburn pruritus.
The objective of this study was to evaluate whether Provase®, a nonprescription moisturizer with a blend of protease enzymes, would reduce postburn itching in adult burn survivors relative to a control moisturizer. This was a prospective, single-center, double-blinded, pilot study where 23 burn survivors were randomized to either the treatment group, who applied Provase, or the control group, who applied the base moisturizer used in Provase every 8 hours for 4 weeks. Twelve were randomized to the treatment and 11 to the control groups with 9 participants in each group completing the study. ⋯ The affective itch characteristics were significantly reduced for the treatment group for bothersome at weeks 1, 2, 3, and 4; for annoying at week 4; and for unbearable at weeks 2, 3, and 4. Although this was a pilot study and not powered for statistical differences, there were statistically significant differences for itch duration, weekly frequency, itch episodes per day, itch TBSA, and reported affective burden of itch after treatment. Further investigation is recommended with a larger sample size treated for a longer period of time where participants are stratified based on acute or chronic itch.
