BACKGROUND The bifurcation into tibial nerve and common peroneal nerve is generally targeted for sciatic nerve block at popliteal approach. However, it is sometimes difficult to determine the exact bifurcation point in clinical situation. The mean distance between the popliteal fossa and division of sciatic nerve (DPDSN) was reported approximately 6 cm ±(More)
PURPOSE To investigate whether ulinastatin pretreatment (6000 U.kg-1 before CPB and before declamping of aorta) influenced the production of cytokines and adhesion molecules in the peripheral circulation. METHODS This prospective randomized study was performed in 22 patients undergoing cardiac surgery. They were divided into two groups. Patients in Group(More)
A 77-year-old female had acute myocardial infarction and ventricular septal perforation (VSP). An operation was performed 14 days after VSP. During cardiopulmonary bypass, a patch was sutured in place on the left side of the defect under a mild hypothermia with topical cardiac cooling procedure. In the postoperative period, mechanical ventilation was(More)
The effects of ulinastatin on the serum interleukin 8 and 6 (IL-8, 6), granulocyte elastase (GEL), creatinphosphokinase (CK) and CK-MB were studied during open heart surgery under cardiopulmonary bypass (CPB). Eleven patients (group I) did not receive ulinastatin. Thirteen patients (group II) received 600,000 units of ulinastatin intravenously before CPB(More)
