Pediatric burn patients often have hypertension and tachycardia for several years post-injury. Propranolol has shown to be effective in treating the hypermetabolic state secondary to a major burn injury. This study was conducted to document a safe and effective dosing regimen for three different age groups. One hundred four burn-injured children with a 30% to 92% total body surface area burn were treated for 1 to 2 years with propranolol in the outpatient setting. Guardians of the patients were instructed on how to take and monitor the systolic blood pressure and heart rate, and document their vital signs several times a day. The documentation was reviewed with the guardian and patient, and based on age-specific vital sign parameters, propranolol dosing adjustment was done to measure at least 15% to 20% reduction in admission heart rate. Mean doses for the age groups were as follows: 0 to 3 years 5.2 ± 2.8 mg/kg/day, 4 to 10 years 4.2 ± 1.8 mg/kg/day, and 11 to 18 years 2.9 ± 1.4 mg/kg/day. The propranolol dose decreased as time post-burn increased. On selected patients, propranolol was stopped due to changes in the heart rate, but at all times, it was safe and effective. No adverse effects were noted. The dosing regimen was not affected by burn size or gender. Propranolol can be safely stopped abruptly with no rebound hypertension. Individuals older than 10 years required a lower dose per kilogram following the burn injury than prepubertal burn survivors. Propranolol proved to be both safe and effective in the management of cardiovascular changes occurring in the hypermetabolic state.

The MolecuLight i:X Imaging Device is a portable, noninvasive, real-time camera used to visualize the bacterial load in a wound. It uses violet light illumination and a dual bandpass optical filter to capture the fluorescence of endogenous structures in the tissue matrix and harmful bacteria. The MolecuLight i:X captures images of wounds and highlights potentially detrimental levels of bacteria. This is an initial evaluation of using the MolecuLight i:X camera in the management of burns to demonstrate the following: the ability of the device to guide clinicians in their management of the burn (ie, detect, identify, and specify swabbing locations). Burn wounds were photographed under standard light and violet light illumination to compare presentations of obvious infection signs and symptoms. Microbiology swab samples were obtained to correlate any bacterial presence to the images. The fluorescence images were used to guide swabs to where the bacteria were congregating. Twenty patients were imaged. Four patients did not have bacterial contamination based on their images and swab results. Sixteen patients showed growth of Staphylococcus aureus, Pseudomonas aeruginosa, or other bacteria. Nine of the patients, by definition, had infections. These findings were correlated with the typical signs and symptoms of infection, the fluorescence images, and the microbiology results. The efficacy of the MolecuLight i:X is evident due to the microbiology results correlating to the images. Further research is being done to test the device in terms of being an early intervention tool. With these early results and guidance of swab samples, the MolecuLight i:X may be able to detect bacterial load before an infection and subsequent graft failure, thereby shortening lengths of hospital stay and improving overall healing.
