31 DISCUSSION

32 The depth of burn is documented as partial or full thickness The extent of burns is assessed using –Wallace Rule of 9 in adult –Lund browder chart in children The palm of pt’s hand represents ~1% of pt’s BSA Burn assessment

33 Classification of burn

34 Lund & Browder charts Wallace rule of 9

35 Parkland’s formula –Total fluid requirement in the first 24H = 4 x pt’s weight (kg) x % TBSA –Infuse the first half in the first 8h –Infuse the rest in the next 16H  Start time = time of burn injury  Fluid of choice = hartmann’s solution Fluid regime

36 Adequate resuscitation is monitored by vital parameters and urine output 0.5 – 1ml/kg/h If urine output falls below 0.5ml/kg/h a bolus of 10ml/kg body weight can be given If urine output >2ml/kg/h the rate of infusion should be reduced

37 Next 24H Total volume = ½ of the first day Colloids (o.5ml/kg/%) and 5% glucose or isotonic glucose saline to make up the rest

38 Consequences of burns 1.Renal failure (acute tubular necrosis d/t hypovolaemia, haemoglobinuria and myoglobinuria) 2.Resp failure (smoke inhalation, airway obstruction, ARDS) 3.Catabolism and nutritional depletion 4.Venous thrombosis 5.Curling’s ulcer and erosive gastritis Short term consequences Early consequences 1.Permanent disfigurement 2.Prolonged hospitalization 3.Psychological problem 4.Impaired function Long term consequences 1.Hypovolaemia (loss of protein, fluid and electrolytes) 2.Metabolic derangements 3.hyponatraemia followed by risk of hypernatraemia, hyperkalaemia followed by hypokalaemia) 4.Sepsis 5.Hemolysis with anemia 6.hypothermia

39 CVS: – Acute phase: transient decrease in cardiac output d/t hypovolaemia, depressed myocardial function, increased blood viscosity and release of vasoactive substance causing poor organ and tissu perfusion – Second phase (metabolic phase) :after 48H  increased blood flow

40 Resp – Early compl : 0-24H – carbon monoxide poisoning and direct inhalational injury  airway obstruction and pulm edem – Delayed 2-5days: adult resp distress syndrome – Late: days to weeks – pneumonia, atelectasis and pulm emboli

41 Risk factors for the development of pneumonia in older adults with burn injury By Tam N. Pham et al. J burn care res jan –feb; 31(1) ‘ 105 – 110 Older adult with burns are at risk for worse outcomes because of factors related to age, comorbidities and response to treatment Pneumonia is the most common infection in hospitalizes burn patients and is frequently assoc with death

42 Respiratory complications in burns: an evolving spectrum of injury Boots, Robert J et all, clinical pulmonary medicine: may 2009 – vol 16 – issue 3 – pp Respiratory complications associated with burn injury are responsible for significant morbidity and mortality and occur in up to 41% of patients admitted to hospital after thermal injury Inhalation injury can be due to a combination of thermal, chemical and systemic effects and is the most significant complication in the early phase post burn injury (first 48hours), predisposing the patient to the development of pulmonary edema, acute respiratory distress syndrome and pneumonia

43 Age and general condition Site of the burn Extent of the burn Depth of the burn Assoc respiratory injury Prognosis of burn

44 Thank you

45 Points to learn Detail hx taking in burn case – Facial and neck involvement – Surrounding area: close vs open Clinical examination: – Sx of burn smoke – Sx of airway involvement: difficult articulation, change of voice, stridor Proper ASA classification Proper intraop management – Invasive monitoring – Fluid management Major burn : >10% in children, >15% in adult Major burn case admit icu – ventilated for airway protection/post op Proper burn management – inhalational, chem,etc Parkland formula is just a guide. Resuscitation must be based on pt’s cond and monitoring
