Independent risk factors for sepsis in patients with large area burns / 中华创伤杂志

ABSTRACT

Objective To determine the independent risk factors for sepsis in patients with large area burns.Methods The study enrolled 307 patients with large area burns treated from June 2014 to June 2015.Related variables included age,gender,visit time,emergency eschar open,burn index,tangential excision of eschar during shock stage,delayed resuscitation during shock stage,oxygen pressure(PaO2),carbon dioxide pressure (PaCO2),assisted ventilation mode,mechanical ventilation time,inhalation injury,prophylactic tracheotomy,continuous lactic acid rise,refractory hypernatremia,heart-lung disease history,and diabetes history.Correlation of the variables with the incidence of sepsis was observed.Independent predictors of sepsis in patients with large burns were differentiated using the Logistic regression analysis.Results Delayed resuscitation during shock period (OR =1.747,95％ CI 1.822-7.431,P ＜ 0.05),continuous lactic acid rise (OR =1.758,95％ CI 1.137-4.002,P ＜ 0.05),refractory hypernatremia (OR =2.985,95％ CI 1.074-6.782,P ＜ 0.05),moderate and severe inhalation injury(OR =14.764,95％ CI 0.892-47.323,P ＜ 0.05) and burn index (OR =5.017,95％ CI 1.075-23.572,P ＜ 0.05) were found be independently associated with sepsis in patients with large burns.Conclusions These independent risk factors for sepsis in large area burn patients deserve more attention.Early and timely treatment measures may reduce the incidence of sepsis.
