Abstract
BACKGROUND: Burn injury is associated with a high mortality risk. Recent epidemiological data on burn injury and mortality rate from Saudi Arabia is lacking. OBJECTIVE: This study aimed to analyze the survival rates and its predictability using the Baux score in patients with burn injury at a tertiary care hospital in Saudi Arabia. MATERIALS AND METHODS: This retrospective study included all patients admitted to the burn unit at King Fahd Hospital of the University, Al Khobar, between March 2014 and February 2020. Patients' burn characteristics and calculated revised Baux scores were collected. The age, burn wound size, type of burn, burn extension, and Baux score of the survivors and non-survivors were compared. RESULTS: A total number of 102 patients were included, and their mean age was 24.2 years (range: 9 months to 78 years). The mean affected total body surface area was 26.4%. Ninety patients (88%) suffered from flame/scald burn. The mortality rate was 17.6% (18 patients); all these patients had flame burns. No patient with a revised Baux score ≥110 survived (n = 14; 77% of the total deaths), while there was no mortality at score <36. Inhalational injuries were reported in 18 patients, of which 13 (72%) died. Patients with patent airway and no inhalation injury were 19 times more likely to survive than those with a compromised airway (P < 0.001). In terms of the depth of burn, partial thickness increased the likeliness of survival by 10 times compared with full thickness (P < 0.003). CONCLUSION: Inhalational injury and burn size were the most prognostic factors of burn injury in this study. As all cases of mortality were from flame burns, regulation on flammable materials and safety measures should be promoted to the public.
