The application of early goal directed therapy in patients during burn shock stage.

Early goal directed therapy (EGDT) provided at the earliest stages of burn shock, has significant benefits for ordinary burn patients, however, its effect on patients with more than 80% of total surface area burned (TBSA) still remains unclear. In this study, 34 extensively burned patients with (87.3±5.6)% of total surface area burned were collected from January 2008 to January 2014. All burn patients here had similar monitoring or treatment modalities. Of these 34 burn patients, 13 patients were treated with EGDT under pulse indicator continuous cardiac output (PICCO) monitoring, and 21 patients were treated with conventional fluid management. Information obtained in the course of treatment included mean arterial pressure (MAP), central venous oxygen saturation (ScvO2), oxygenation index (PaO2/FiO2), blood lactic acid and urine volume, infusion volume (mL·1% TBSA-1·Kg-1), complications of over-resuscitation (hydrothorax or pulmonary edema), case rate of burn sepsis and fatality. Our results demonstrated that there existed significant difference between the two groups in parameters below: 1. Higher ScvO2 (%) after EGDT (EGDT: 78.1±8.6, CG: 65.5±11.2; t=-3.446, P<0.05), 2. Higher PaO2/FiO2 after EGDT (EGDT: 381.4±56.6, CG: 328.9±48.6; t=2-875, P<0.05), 3. Lower mean infusion volume after EGDT (mL·1% TBSA-1·Kg-1) (EGDT: 3.29±0.26, CG: 3.71±0.31; t=5.292, P<0.05), 4. Lower complications of over-resuscitation after EGDT (EGDT: 2/13, CG: 15/21; P<0.05); However, no statistical significance existed in parameters below: 1. MAP (EGDT: 76.2±13.1, CG: 74.3±15.6; t=-0.36, P>0.05), 2. Urine volume (EGDT: 0.83±0.12, CG: 0.85±0.17; t=0.370, P>0.05), 3. Case of burn sepsis (EGDT: 13/13, CG: 20/21; P=1), 4. Case fatality (EGDT: 1/13, CG: 3/21; P=1). The finding results showed that patients with more than 80% of total surface area burned during burn shock phase could get better outcome from EGDT.
