[Therapeutic goals for fluid management in profound shock].

The therapeutic goals for fluid replacement in 9 patients were studied. Five cases in sepsis, 2 in necrotizing pancreatitis and 2 in fat embolism were treated as dehydration or hypovolemia. Fluid replacement was performed with the view of obtaining the amelioration of circulation and urine output, even if CVP or PCWP had been elevated on admission. The values of CVP and PCWP, renal function and pulmonary function were assessed retrospectively. Out of 9 patients, one died of refractory shock, brain edema due to fat embolism and remaining one after recovery of shock. Out of 6 survivors, 2 showed oliguric renal failure, and 2 nonoliguric renal failure. The volume of administered fluid ranged from 5445 ml/10 hrs to 15820 ml/14 hrs and speeds of fluid administration were 545 ml/hr to 1248 ml/hr. CVP value on admission ranged from 4.0 to 22.0 cmH2O (3.0 to 16.3 mmHg), mean value 14.0 +/- 6.5 cmH2O. Through the course, the highest CVP and PCWP ranged from 12.5 to 26.5 (mean 19.8) mmHg and 14 to 36 (mean 20.9) mmHg, respectively. Out of 9 patients, 8 were suffering from respiratory distress, however, 7 recovered by PEEP except for one refractory shock. High values of CVP or PCWP could be recognized even if in hypovolemic shock and/or septic shock. Maintenance of higher values (18-20 mmHg) in CVP and/or PCWP during fluid resuscitation might be recommended because adequate fluid resuscitation could sustain the renal function, and result in good outcome.
