[Effect of fibrinogen concentrate on coagulopathy patient with left ventricular assist system in surgical repair of thoracic abdominal aortic aneurysm (TAAA): a case report].

We describe a case in which fibrinogen concentrate was useful to improve anticoagulation after aortic graft replacement. A 44-year-old man with left ventricular assist system (LVAS) underwent thoracic abdominal aortic aneurysm (TAAA) graft replacement. LVAS requires anticoagulant therapy for thromboprophylaxis.

[Time course changes in perfusion index and pleth variability index during electroconvulsive therapy].

Background: Electroconvulsive therapy (ECT) is a widely acceptable therapy for psychiatric symptoms. ECT provokes abrupt hemodynamic changes, and sometimes induces serious cardiac complications. In this study, we examined the time course of changes in perfusion index (PI) and pleth variability index (PVI) during ECT using Radical-7 (Masimo Corp.

[Removal of sevoflurane and nitrous oxide from waste anesthetic gases by using Anesclean, the system for treating waste anesthetic gases].

Background: The system for treating waste anesthetic gases, Anesclean, has been developed recently. This system can collect volatile anesthetics from waste anesthetic gases, and then decompose nitrous oxide (N2O) into N2 and O2 immediately. The purpose of this study was to investigate the efficacy of this treating system, Anesclean, on removal of greenhouse effect gases in our university hospital.

Comparison of the effects of vasopressin and norepinephrine on organ perfusion during septic shock in streptozotocin-induced diabetic rats.

Purpose: The purpose of this study was to compare the effects of norepinephrine (NE) and vasopressin on systemic hemodynamics, renal and mesenteric artery blood flow, inflammatory response and inducible nitric oxide synthase (iNOS) activity during endotoxin shock in streptozotocin-induced diabetic rats.

Methods: The study was designed to include three sets of experiments: (1) measurement of changes in systemic hemodynamics and mesenteric and renal artery blood flow; (2) measurement of biochemical variables; and (3) measurement of iNOS activity in the mesenteric artery. Systemic hemodynamics, regional artery blood flow changes and biochemical variables were assessed before treatment and 1, 2 and 3 h after treatment.
