[Anesthetic management of pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension--series of severe cases].

We report seven cases of anesthetic management for pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension (CTEPH) during past seven years in our hospital. All the patients were suffering from right heart failure and pulmonary hypertension, and the preoperative mean pulmonary artery pressure (mPAP) was 51.2 +/- 10.

Anesthetic management for severe aortic regurgitation in an infant repaired by Ross procedure.

We report the anesthetic management of a 7-month-old male infant with severe aortic regurgitation (AR) scheduled for the Ross procedure. To the best of our knowledge, this is the first report from the viewpoint of anesthetic management for the Ross procedure performed in an infant. He had been suffering from severe AR that occurred suddenly when he was 5 months old.

[Postoperative inflammatory reactions after coronary artery bypass grafting performed on-pump with preceding glucocorticoid therapy compared with those after grafting performed off-pump].

Background: Compared with conventional coronary artery bypass graft surgery (CABG) using cardio-pulmonary bypass, less postoperative acute inflammatory responses are expected in off-pump CABG. Therefore, we retrospectively studied the difference in postoperative inflammatory reactions between on-pump and off-pump surgical groups.

Methods: We selected 15 patients for on-pump and 19 for off-pump groups, respectively, from the past 3 years.

[Stored autologous blood from a pregnant woman showing a considerable amount of agglutinates].

A 30-year-old woman was admitted to our hospital to undergo simultaneous cesarean section and radical hysterectomy when the pregnancy became 30 weeks. An ultrasonic examination had found hypoechoic region at the cervix uteri. Because she wished autologous blood transfusion, 100 ml each of her own blood was obtained 3 times preoperatively.

Performance of a tonometer for arterial pressure measurement during anesthesia in the elderly.

We investigated performance of an arterial tonometer during anesthesia in the elderly. Thirty patients (17 men and 13 women), ranging from 70 to 86 years old, were included, and agreement between tonometric arterial pressure (TAP) and intraarterial pressure (IAP) was calculated. A total of 6487 paired points was sampled, and values for precision (mean absolute difference +/- SD) were 6.
