The prophylactic effect of nicorandil on perioperative coronary spasm (CS) in CABG was examined retrospectively. The subjects were 313 patients who had undergone elective CABG. The patients were divided into two groups a control group receiving single administration of nitroglycerine (N = 196) and a nicorandil group receiving both nitroglycerine and(More)
Hemodilution with colloid solution is known to influence blood coagulation. To evaluate the effectiveness of hemodilution on ACT, 156 patients undergoing elective coronary artery bypass grafting were studied. Patients were divided into three groups (Group I of 52: without hemodilution, Group II of 52: normovolemic hemodilution with Dextran 40, Group III of(More)
BACKGROUND The level of arterial carbon dioxide partial tension (PaCO2) is a sine qua non for the determination of the adequacy of ventilation. The aim of this study was to assess the usefulness of SenTec Digital Monitor System in measuring transcutaneous arterial carbon dioxide partial tension (PCO2) non-invasively for the management of chronic respiratory(More)
We applied a continuous intra-arterial blood gas monitoring system (Paratrend 7) to a patient with pulmonary alveolar proteinosis during pulmonary lavage. Lavage was performed under general anesthesia with one lung ventilation. We inserted the sensor of Patatrend 7 through a 20 G catheter into the radial artery, and monitored pH, PaCO2 and PaO2 continuously(More)
The purpose of this study was to examine retrospectively the effect of amrinone on platelet counts and blood transfusion volume during CABG. Patients were divided into two groups. Amrinone group included 40 patients and for comparison another group included 33 patients who had undergone CABG without amrinone. Anesthesia and surgical procedures were(More)
In this study, we investigate the e ectiveness of an unknown word processing(UWP) algorithm, which is incorporated into an N-gram language model based speech recognition system for dealing with lled pauses and outof-vocabulary(OOV) words. We have already been investigated the e ect of the UWP algorithm, which utilizes a simple subword sequence decoder, in a(More)
We have recently encountered three patients who developed prolonged muscle paralysis after long-term infusion of muscle relaxants and administration of large doses of steroids. Among many factors implicated in the cause of this paralysis, steroids and muscle relaxants were suggested to be most likely causative agents. In order to avoid such muscle(More)
Twenty male volunteers, average age 24 years, participated in this study. Specimens were obtained by enamel biopsy using 5 microliters of 0.5 M HClO4 for 30 s. Using a regression curve, comparisons of fluoride concentrations were made at different depths. The fluoride concentrations (mean +/- SE) at a depth of 5 microns were highest in the distobuccal (1698(More)
