Vasopressin deficiency and vasodilatory state in end-stage liver disease.
Relative vasopressin deficiency, a contributor to vasodilatory septic shock, also may be a cause of the vasodilatory state in liver disease. This study assessed endogenous vasopressin levels in patients with liver disease and their hemodynamic response to exogenous vasopressin. ⋯ Patients with liver disease have lower vasopressin levels than controls and respond with a brisk vasoconstrictor response to exogenous vasopressin. Therefore, relative endogenous vasopressin deficiency may contribute to vasodilatory shock in liver disease similar to what has been observed in septic shock.

Risk factors for gastrointestinal complications in patients undergoing coronary artery bypass graft surgery.
To determine the risk factors for the development of gastrointestinal complications (GICs) after coronary artery bypass graft (CABG) surgery. ⋯ A delayed diagnosis of complications is an important problem in the management of major surgical GICs. The present results suggest that surgeons and intensivists must be alert to patients older than 70 years, a cardiopulmonary bypass time longer than 60 minutes, reoperation for bleeding after CABG surgery, and postoperative creatinine level higher than 1.7 mg/dL.

Effects of fenoldopam mesylate infusion on splanchnic perfusion after myocardial revascularization on cardiopulmonary bypass: an ultrasound Doppler study.
To measure the effects of fenoldopam mesylate infusion on splanchnic blood flow in patients undergoing myocardial revascularization with cardiopulmonary bypass. ⋯ The infusion of fenoldopam increased the flow through the celiac artery and superior mesenteric artery; the effect was higher for the latter. These changes did not affect the hemodynamic variables.
