ABSTRACT
ObjectiveTo investigate the changes of arterial base deficits (BD) in the early stageof extensive burned patients. MethodsWe perform a retrospective review of 126 patients with a totalbody surface area (TBSA) over 30% whose resuscitations were initiated with the Ruijin formula to ob-serve the BD changes and analyze the relationship of BD and TBSA at different postburn time intervals insurvivors and deaths. ResultsWithin 48h after burn injury, the BD value improved gradually. Thedifference between survivors and nonsurvivors was significant at 4 to 8h interval after burn injury ( P <0.05). BD was correlated with TBSA strongly during 4 to 16h after burn injury ( P ≤0.05)in nonsur-vivors, but not in survivors. The incidence of the shock－ related complications in survivors was higherthan in nonsurvivors. ConclusionBD could be one of monitor index in the shock stage after severeburM injury.
