Randomized Controlled Trial Clinical Trial
Hemofiltrastion does not influence early S-100B serum levels in septic shock patients receiving stress doses of hydrocortisone or placebo.
The prognosis in patients with hyperdynamic septic shock correlates with the presence and the severity of septic encephalopathy. However, the neurological evaluation is considerably influenced by the use of analgesia sedation during mechanical ventilation. An early concentration peak of the neuroprotein S-100B in serum reflects both cellular damage at an increased permeability of the blood-brain-barrier and a delayed renal elimination. Thus, the objective of this study was to analyze the effect of continuous veno-venous hemofiltration (CVVH) on early S-100B serum levels in septic shock patients, who were treated with either stress doses of hydrocortisone or placebo. ⋯ Early S-100B serum levels in septic shock patients receiving either stress doses of hydrocortisone or placebo were not influenced by CVVH. For the first time, we observed a similar extent of S-100B serum increase in CVVH patients, who had significantly higher S-100B serum values compared to those without CVVH, as reported for out-of-hospital cardiac arrest or severe traumatic brain injury. Hypercortisolemia induced by the infusion of stress doses of hydrocortisone did not significantly reduce early S-100B serum concentrations with time.
