Randomized Controlled Trial Multicenter Study Clinical TrialAn immune-enhancing enteral diet reduces mortality rate and episodes of bacteremia in septic intensive care unit patients.
To determine whether early enteral feeding in a septic intensive care unit (ICU) population, using a formula supplemented with arginine, mRNA, and omega-3 fatty acids from fish oil (Impact), improves clinical outcomes, when compared with a common use, high protein enteral feed without these nutrients. ⋯ Immune-enhancing enteral nutrition resulted in a significant reduction in the mortality rate and infection rate in septic patients admitted to the ICU. These reductions were greater for patients with less severe illness.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of the phosphodiesterase III inhibitors olprinone, milrinone, and amrinone on hepatosplanchnic oxygen metabolism.
To measure the hepatic venous oxygen saturation in patients after cardiac surgery and to compare the effects of olprinone (OLP), a newly synthesized phosphodiesterase III inhibitor, with those of milrinone (MIL) and amrinone (AMR) on hepatosplanchnic oxygen dynamics. Phosphodiesterase III inhibitors are used to improve the hemodynamic state after cardiac surgery. However, the effect of these agents on the hepatosplanchnic circulation has not been investigated thoroughly. ⋯ These results suggest that OLP enhances hepatosplanchnic blood flow and thus may be beneficial in protecting the hepatosplanchnic organs after cardiac surgery.

Comparative StudyEvaluation of a thoracic bioimpedance cardiac output monitor during cardiac catheterization.
To evaluate the accuracy and precision of an advanced thoracic bioimpedance cardiac output monitor by comparing it with conventional thermodilution. ⋯ The correlation between conventional thermodilution and thoracic bioimpedance cardiac output estimates was good and the standard deviation of the differences was lower than that reported for commercially available devices. The system can be used in the cardiac catheterization lab for reliable and continuous noninvasive measurement of cardiac output.

Randomized Controlled Trial Clinical TrialCarbamezapine for pain management in Guillain-Barré syndrome patients in the intensive care unit.
To evaluate carbamezapine (CBZ) for neuritic pain relief in Guillain-Barré syndrome (GBS) patients in the intensive care unit (ICU). ⋯ The pain in GBS has a dual origin, and we recommend CBZ as an adjuvant to treat pain in GBS patients, during the recovery phase in the ICU, to reduce the narcotic requirement.

The hemodynamic effects of inhaled nitric oxide and endogenous nitric oxide synthesis blockade in newborn piglets during infusion of heat-killed group B streptococci.
To determine the effects of therapy with inhaled nitric oxide (NO) gas and partial or complete blockade of endogenous NO synthesis with N(omega)nitro-L-arginine (L-NA) on the hemodynamic responses to group B streptococci infusion in newborn piglets. ⋯ Pulmonary hypertension and shock resulting from GBS infusion in newborn piglets are much worse if endogenous NO production is completely inhibited. Continuous inhaled NO with or without low-dose L-NA inhibits the decrease in cardiac output.
