[Perioperative fibrinogen concentrations in cardiac surgery with cardiopulmonary bypass].

Background: Patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) need many blood products due to deficiency of coagulation factors. Blood transfusion therapy in patients with excessive bleeding after CPB is generally empiric. We checked and studied the fibrinogen concentration and transfusion, as well as bleeding amount in the perioperative period.

[Use of landiolol hydrochloride for the prevention of atrial fibrillation after lung resection].

Background: We examined the effect of landiolol hydrochloride, a selective beta1-adrenoreceptor antagonist, on the incidence of atrial fibrillation(AF).

Methods: The incidence of AF after lung resection was evaluated retrospectively in patients with intraoperative treatment with landiolol hydrochloride or those without it. Landiolol hydrochloride (5 microg x kg(-1) x min(-1)) was administered intravenously from the beginning of anesthesia induction to the end of operation.

[The effect of corticosteroids on postoperative course after esophageal resection for carcinoma].

Background: The effect of steroids against inflammatory mediators is well known, but its benefit and adverse effect on the postoperative clinical course are uncertain after esophageal resection for carcinoma.

Methods: Forty-three cases undergoing esophageal resection for carcinoma were studied retrospectively. Twenty-six cases, given corticosteroids during operation or first postoperative day, were classified as the steroid group, and the other 17 cases were defined as the control group.
