['Two years ago the authors began to use Swan-Ganz catheters to generate more complex hemodynamic data as a better guide to resuscitation of burns. This study uses the information to identify differences between survivors and nonsurvivors.', 'Fifty-three consecutive patients with major burns were treated using Swan-Ganz-generated data. Additional information was collected, including demographics, intake and output, medications, and arterial blood gas (including calculated oxygen consumption). Statistical analysis incorporated adjustments for autocorrelation.', 'The patients included 38 men and 15 women, averaged 43.7 years of age, and had a mean burn size of 40%. Thirteen patients suffered severe inhalation injury. Data collected hourly over 3 days were collapsed across 6-hour observation periods. Mean values, when plotted across time, discriminated the 37 survivors from the 16 nonsurvivors. Poor response to resuscitation as evidenced by increased use of colloid fluid and cardiotonic drugs plus failure to maximize oxygen consumption were associated with nonsurvival.'] Do survival in major burn injuries is predicted by early response to Swan-Ganz-guided resuscitation?
