Once-daily aminoglycoside dosing (ODA) is used in most patient populations to optimize antibacterial activity and reduce toxicity. Unfortunately, burn patients are excluded from ODA due to concerns over altered pharmacokinetics resulting in a shortened half-life and low peak aminoglycoside concentrations. Retrospective studies suggest that ODA may be appropriate if higher milligram/kilogram doses are used. However, no prospective clinical trials in burn patients exist to confirm these findings. ⋯ Burn patients with adequate renal function and <20% TBSA are candidates for ODA. Tobramycin half-life was similar to healthy, non-burn patients. The larger than normal volume of distribution supports the use of the higher empiric dose of 10mg/kg total body or adjusted weight in non-obese and obese patients, respectively, with further dose adjustment based on therapeutic drug monitoring.

An overabundant discharge of inflammatory mediators plays a significant role in intestinal injury throughout the early stages of critical burns. The present study aims to explore the outcome of 200mM hypertonic saline (HS) resuscitation on the intestinal injury of critically burned rats. ⋯ The overall findings of this study suggest that preliminary resuscitation with 200mM HS after severe thermal injury reduces intestinal edema, inhibits systemic inflammatory response, and attenuates intestinal p38 MAPK activation, thus reduces burns-induced intestinal injury.

Polyneuropathy is a debilitating condition which may be associated with large burns. The aim of this integrative review is to identify factors that contribute to the development of critical care polyneuropathy in patients admitted to an intensive care unit with a severe burn injury. PubMed, Scopus, CINHAL and EMBASE were searched up until July 2016. ⋯ Overall, factors identified as contributing to the development of critical care polyneuropathy in burn injured patients included prolonged ventilation (>7 days), large and deep total body surface area burns (mean TBSA 40%), and sepsis. Critical care polyneuropathy in burn patients remains challenging to diagnose and treat. To date, there is a lack of long term studies describing the impact of critical care polyneuropathy on functional performance or participation in activities of daily living in the burns population and this is consistent with the general literature addressing the lack of follow up assessments and long term consequences of persistent muscle weakness.

Early excision of burns reduces the incidence of local and systemic infections caused by colonising microorganisms, and reduces mortality and length of hospital stay. Appropriate antibiotic prophylaxis can reduce the risk of postoperative wound infections and skin graft loss. Antibiotic selection should be based on likely pathogens. However, there are few studies that have investigated the early pathogenic colonisers of acute burn wounds. ⋯ Increased colonisation of acute burn wounds with pathogenic gram-negative bacteria was associated with increased size of burn.

To study the relationship between day of admission and important outcomes among patients with burn injuries. ⋯ Weekend admission is associated with increased mortality among patients with burn injury >65years old. Weekend admission is also associated with increased morbidity and prolonged length of stay.
