Background: Burns patients have been shown to exhibit a hyper-metabolic state of activity which can persist for up to two years post-burn. The relationship between total body surface area (TBSA) burned and resting metabolic rate (RMR) has been investigated in larger burns (≥20% TBSA), however not in small-moderate burns (≤15% TBSA). The majority of previous studies have looked at burns ≥ three months after the initial injury. This observational study examined acute effects of small-moderate burns (<15% TBSA) on RMR in burns patients using indirect calorimetry with the secondary aim to investigate the effects of surgery on RMR. Caloric intake was also recorded for comparison to RMR to determine energy balance.

Methods: 39 participants (32 male and 7 female) were included in this study via the inpatient burns ward at Fiona Stanley Hospital. Each patient was recruited upon admission to the ward with the day of the initial burn being considered as day 0. Data was collected on day four as able (± one day) and one day prior to and post-surgery as able.

Results: The pooled data bivariate correlation showed a significant weak relationship between RMR and TBSA (r=0.435, p=0.009), a significant relationship was also found between RMR and TBSA in males (r=0.634, p=0.001). Patients displayed a positive energy balance of 116kcal/day. The pre and post-surgery RMR data was found to be a non-significant change of -16kcal/day (t=-0.189, p=0.28).

Conclusion: This study demonstrated a moderate-strong correlation of RMR and TBSA in males for burns of ≤15% TBSA. The energy balance data showed an average difference of +116kcal/day aligning with the research showing that patients are fed conservatively during a burn injury.
