Thermal injury within the first 4 months of life

Abstract

Aim To determine the incidence, magnitude of injury, fluid management, role of surgery and outcome in newborns and infants under 4 months of age admitted to a Burns Unit. Method Retrospective analysis of patient records. Results 86 patients under the age of 4 months were admitted over a 37 year period (0.34% of admissions). Their injuries were caused by hot water in 45 and fire in 38, primitive heating devices in 2 and non-accidental paraffin burn in 1. Twenty-eight sustained superficial partial thickness burns, 12 deep partial thickness and 46 full thickness injuries. The total body surface area ranged from 1 to 55% with an average of 11.5%. Bacterial contamination of the burn wounds was present on admission in 52.3% and consisted of both gram positive and gram negative organisms. The resuscitation formula of 3.5 ml/kg/% burn on the first day and 1.5 ml/kg/% burn on the second day plus maintenance fluid at 30–120 ml/kg/day was not always adequate in maintaining haemodynamic stability. Three surgical methods were employed in 59 patients (69%). These included early tangential excision in 25, excision with or without allograft and delayed grafting in 27, and conventional therapy with eventual grafting in 7 patients. Releasing escharotomies were required in 9 children. Nineteen children required amputations. Three craniectomies, 2 tracheostomies and 1 colostomy were additional procedures. The mortality was 9.3%. Three causes of death were identified: magnitude of injury, sepsis and inhalation injury. Conclusion Neonates and infants are very vulnerable and preventable environmental factors are often implicated. Fire and hot water are the most common causes resulting in significant physical trauma. Resuscitation especially during the first few days of life can be problematic. Wound infection and sepsis are common and surgery should be individualised. Long-term outcome is very satisfactory for those with small burns however those with larger burns may remain permanently disfigured.
