OBJECTIVE: To evaluate the effects of early short-term, isovolaemic haemofiltration at 45 ml/kg/h on physiological and clinical outcomes in patients with septic shock. DESIGN: Retrospective study before and after a change of unit protocol (study period 8 years). SETTING: Intensive care unit of metropolitan hospital. PATIENTS: Eighty patients with septic shock. INTERVENTIONS: Introduction of a new septic shock protocol based on early isovolaemic haemofiltration (EIHF). In the pre-EIHF period (before), 40 patients received conventional supportive therapy. In the post-EIHF period (after), 40 patients received EIHF at 45 ml/kg/h of plasma-water exchange over 6 h followed by conventional continuous venovenous haemofiltration (CVVH). Anticoagulation policy remained unchanged. MEASUREMENTS AND MAIN RESULTS: The two groups were comparable for age, gender and baseline APACHE II score. Delivered haemofiltration dose was above 85% of prescription in all patients. PaO2/FiO2 ratio increased from 117+/-59 to 240+/-50 in EIHF, while it changed from 125+/-55 to 160+/-50 in the control group (p<0.05). In EIHF patients, mean arterial pressure increased (95+/-10 vs 60+/-12 mmHg; p<0.05), and norepinephrine dose decreased (0.20+/-2 vs 0.02+/-0.2 microg/kg/min; p<0.05). Among EIHF patients, 28 (70%) were successfully weaned from the ventilator compared with 15 (37%) in the control group (p<0.01). Similarly, 28-day survival was 55% compared with 27.5% (p<0.05). Length of stay in the ICU was 9+/-5 days compared with 16+/-4 days (p<0.002). CONCLUSIONS: In patients with septic shock, EIHF was associated with improved gas exchange, haemodynamics, greater likelihood of successful weaning and greater 28-day survival compared with conventional therapy.
