Randomized Controlled TrialA randomized, double-blind, placebo-controlled study assessing the anti-inflammatory effects of ketamine in cardiac surgical patients.
To determine whether ketamine administration affects markers of inflammation in cardiac surgery with cardiopulmonary bypass (CPB) and to investigate differences between 2 low-dose ketamine regimens. ⋯ Low-dose ketamine (0.5 mg/kg) attenuates increases in CRP, IL-6, and IL-10 while decreasing vasodilatation after CPB.

Comparative StudyImpact of vasopressin on hemodynamic and metabolic function in the decompensatory phase of hemorrhagic shock.
To explore how the potent vasoconstrictive features of vasopressin impact the rate of cardiovascular collapse and metabolic derangements associated with prolonged hemorrhagic shock. ⋯ Administration of vasopressin used as an adjunct to maintain blood pressure in the decompensatory phase of hemorrhagic shock slows cardiovascular collapse, but has an adverse effect on metabolic and hemodynamic function. Further investigation is warranted to clarify the role of vasopressin in the delayed management of severe hemorrhagic shock.

Fenoldopam inhibits nuclear translocation of nuclear factor kappa B in a rat model of surgical ischemic acute renal failure.
Vasoactive compounds are known to modulate gene transcription, including nuclear factor kappa B (NF-kappaB), in renal tissues, but the molecular effects of fenoldopam in this setting are not known. The authors used a rat model of surgical acute ischemic nephropathy to test the hypothesis that fenoldopam attenuates ischemia/reperfusion (I/R)-induced NF-kappaB-mediated inflammation. ⋯ Data from this rat model of renal I/R suggest that the mechanism by which fenoldopam attenuates I/R-induced inflammation appears to involve inhibition of NF-kappaB translocation and signal transduction.
