[The effectiveness of a system using re-useable linens to reduce the expense of surgical operations].

We introduced a system that uses re-useable linens for surgical operations in 2008. After 3 years from introduction we were able to reduce the expense of about yen 4,340,000 per year and CO2 production of 9,548 kg CO2 x m(-2) per year. We were convinced of the effect on reducing the expense of surgical operations and of decreasing the level of CO2 production that leads to global warming.

[Effect on fetal umbilical arterial blood of administration of vasopressors for hypotension after spinal anesthesia during cesarean section].

Spinal anesthesia was performed in 40 patients undergoing cesarean section. When systolic blood pressure dropped below 100 mmHg, phenylephrine 100-200 microg (P group) or ephedrine 5-10 mg (E group) was administered. The pH of the umbilical arterial blood was collected after delivery of the baby.

[Anesthetic management for a patient with anti-phospholipid antigen syndrome].

A 54-year-old man with anti-phospholipid antigen syndrome (APS) was to undergo artifitial vascular replacement for arteriosclerotic obliterans. APS is characterized by the presense of anti-phospholipid antibodies, hypercoagulability, and prolonged phospholipid dependent coagulation such as activated clotting time (ACT). Perioperative thrombotic complications are frequent among patients with anti-phospholipid antigen syndrome.

[Anesthetic management of concomitant off-pump coronary artery bypass grafting and complete pneumonectomy for lung cancer].

A 69-year-old man was scheduled for combined surgery involving off-pump coronary artery bypass grafting (OPCABG) for coronary stenosis and total pneumonectomy for lung cancer. Anesthesia was maintained with fentanyl, thiopental, sevoflurane, nitrous oxide, and epidural anesthesia using 1.0% mepivacaine.

[Anesthetic management for cesarean delivery in a patient with May-Hegglin anomaly].

May-Hegglin anomaly (MHA) is a rare hereditary disorder characterized by thrombocytopenia and giant thrombocytes and continuous appearance of inclusion bodies (Dohle like corpuscles) in the cytoplasm of granulocytes. A 26-year-old woman with MHA underwent cesarean delivery under general anesthesia, although she had no history of bleeding. The platelet count was 4.

[The effect of repeated sevoflurane anesthesia on hepatic function and immunological system].

Background: Sevoflurane is known as a useful and safe anesthetic because of its properties of fast uptake and elimination at the lungs and of no effects on hepatic function. In this study we examined the effect of repeated sevoflurane anesthesia on hepatic function and immunological system.

Methods: Eight patients (ASA, PS 2 or 3) received sevoflurane anesthesia three times in 6 months.
