Hypertonic Saline In Stabilized Hyperdynamic Sepsis

Hypertonic saline with or without colloidal solution has been successfully used for treating hemorrhagic shock in animal experiments and clinical studies. Due to its various effects at systemic, organ, and microcirculatory levels, the substance appears to be a promising candidate for improving tissue oxygenation in sepsis. We therefore investigated the hypothesis that infusion of hypertonic saline would further improve O-2 delivery, O-2 extraction, and O-2 uptake in hyperdynamic septic shock patients already stabilized by adequate volume and catecholamine infusion. Twenty-one patients received 2-4 mL/kg body weight of hypertonic saline in hydroxyethyl starch within 15 min. This hypertonic saline infusion caused a rapid significant increase in O-2 delivery by 14% but only a marginal increase in O-2 consumption (7% by cardiovascular Fick [p < .05], 4% by respiratory gases [n.s.]). Hypertonic saline increased the already elevated cardiac output by 24%. The pulmonary capillary wedge pressure increased from 14 +/- 3 to 23 +/- 3 mmHg and pulmonary shunt fraction increased 15%, but arterial PO2 did not fall. Except for the increase in pulmonary capillary wedge pressure, none of the cardiovascular changes lasted longer than 60 min. Plasma sodium levels increased from 138 +/- 25 to 163 +/- 38 mmol/L and normalized within 24 h. In these hyperdynamic septic patients, hypertonic saline infusion produced a transient increase in circulation, but no evidence of a substantial increase in O-2 consumption. Either there was no significant O-2 debt due to the already elevated O-2 delivery levels at baseline (700 mL/min/m(2)) or the global O-2 measurements we used were not able to detect discrete regional hypoxia.
