[Efficacy of goal-directed therapy in the treatment of septic shock].
OBJECTIVE
To investigate the efficacy and effect on outcome of goal-directed therapy in patients with septic shock compared with conventional therapy.


METHODS
Sixteen patients with septic shock were randomly assigned to receive goal-directed therapy, with central venous pressure (CVP) 8-12 mm Hg (1 mm Hg=0.133 kPa), mean arterial pressure (MAP) >or=65 mm Hg, venous oxygen saturation (SvO(2))>0.70 (superior vena cava saturation), and urine output >or=0.5 ml/min as therapeutic goals. Another 17 patients received conventional therapy as controls. The arterial oxygen saturation (SaO(2)), SvO(2), MAP, CVP, heart stroke volume cardiac index (CI), serum lactate, volume of fluid, amount of vasopressors, the numbers of organ injured and patients who needed continuity blood purification (CBP) and/or ventilation were recorded serially for 6-48 hours, and they were compared between the two groups. The mortality of the patients in two groups on 7 days and 14 days were also recorded.


RESULTS
There were no significant differences between the groups with respect to base-line characteristics. During the interval from 24 to 48 hours, the patients assigned to goal-directed therapy had a significantly higher in SaO(2), SvO(2), MAP, CVP, CI (P<0.05 or P<0.01), a lower lactate concentration (P<0.01), significantly more fluid during 6-24 hours and less vasopressors (both P<0.01). Seven and 14 days in-hospital mortality were lower in goal-directed therapy group as compared with the control group(P<0.05).


CONCLUSIONS
The efficacy of goal-directed therapy in patients with septic shock is significantly better than conventional therapy in ameliorating outcome of shock and can be easily used in intensive care unit (ICU).
