Acute Normovolemic Hemodilution on ROTEM in Cardiac Surgery

Mitral RegurgitationMitral Stenosis1 more

Impact of acute normovolemic hemodilution (ANH) using hydroxyethyl starch before initiating cardiopulmonary bypass (CPB) on whole blood viscoelastic profile after CPB has not been well established. Patients undergoing cardiac surgery employing moderate hypothermic CPB (n=40) are randomly allocated into one of two groups: in Group-ANH(n=20), ANH is applied by using a balanced hydroxyethyl starch (HES 130/0.6); and in Group-C, ANH is not applied. After weaning from CPB, intergroup differences of INTEM, EXTEM, FIBTEM and APTEM profiles are analyzed. As a primary outcome, inter-group difference between maxiaml clot firmness of EXTEM will be determined at 10 min after ANH in Group-ANH and that at control.

General and specific objectives of the search: evaluate the effects of the administration of Antithrombin III (ATIII) on the activation of the coagulation system and of the fibrinolysis, platelet function, inflammatory response and markers of organ damage in patients undergoing cardiac surgery by cardiopulmonary bypass (CPB) with low plasma levels of post-operative Antithrombin (AT).

Late Clinical Outcomes of Percutaneous Mitral Commissurotomy in Patients With Mitral Stenosis

Mitral Valve Stenosis

In this retrospective cohort study, out of 220 patients who had undergone successful PTMC between 2006 and 2018, the clinical course of 186 patients could be successfully followed. Peri-procedural clinical and echocardiographic data were collected for these patients. Cardiac-related death, undergoing a second PTMC or mitral valve replacement (MVR) were considered adverse cardiac events in follow-up for the purpose of this study. Patients with no history of these events were contacted and asked to undergo echocardiographic imaging, in order to assess the prevalence of mitral valve restenosis, defined as mitral valve area (MVA) < 1.5 cm2 and loss of ≥50% of initial area gain

Acute Normovolemic Hemodilution on Serum-creatinine Concentration in Cardiac Surgery

Mitral RegurgitationMitral Stenosis1 more

Serum-creatinine level (s-Cr) is an important factor for predicting perioperative patient's outcome regarding acute kidney injury. Although cardiopulmonary bypass (CPB), an essential procedure for cardiac surgery, dilutes patient's blood components, possible impact of applying acute normovolemic hemodilution (ANH) and CPB on s-Cr has not been well investigated. In patients undergoing cardiac surgery employing moderate hypothermic CPB (age 20-71 years, n=32), ANH will be randomly applied to 15 patients (Group-ANH) but not in 17 patients (Group-C) before initiating CPB. For ANH procedure consisting of 5 ml/kg of blood salvage and administering 5 ml/kg of balanced hydroxyethyl starch (HES) 130/0.4 for 15 min will be started at 30 min after anesthesia induction and before CPB application for surgery. In both groups, moderate hypothermic CPB will be initiated by using 1600-1800 ml of bloodless priming solution. The changes of hematocrit (Hct), Na+, K+, HCO3-, Ca2+, osmolarity, s-Cr will be determined before ANH (T1), after the first ANH of 2.5 ml/kg (T2), and after the second ANH of 2.5 ml/kg (T3), 30 sec and 60 sec after the initiation of CPB (T4, T5), immediately and 1 hour after the weaning from CPB (T6, T7) and at the end of surgery (T8). S-Cr will be determined by using a point-of-care test device (StatSensor™ Creatinine, Nova Biomedical, USA).
