Abstract
Recent studies have indicated that protective lung strategies may improve outcomes in acute lung injury. We hypothesized that the use of a lower tidal volume early during septic shock may protect against the subsequent development of acute lung injury. Fourteen fasted, anesthetized, invasively monitored, mechanically ventilated, female sheep (26.4 ± 4.5 kg) underwent cecal ligation and perforation to induce sepsis. Sheep were then randomized to ventilation with low (6 mL/kg) or high (12 mL/kg) tidal volumes. A positive end-expiratory pressure of 10 cmH2O was applied in each case. Ringer’s lactate was titrated to maintain pulmonary artery occlusion pressure at baseline levels. No vasoactive agents or antibiotics were used. Survival time was longer in the low- than in the high-tidal-volume group (21.8 ± 2.4 vs. 17.6 ± 4.1 h, respectively, P PKeywords
