A novel technique for ultrasound-guided central venous catheterization under short-axis out-of-plane approach: "stepwise flashing with triangulation".

In ultrasound-guided central venous catheterization, there is no standard technique either for the needle tip visualization or for the adequate needle angle and entry to the skin with short-axis view under out-of-plane technique. In the present study, we propose a novel technique named "stepwise flashing with triangulation", and the efficacy of this technique is assessed. Before and after a didactic session in which the technique was explained, 12 novice residents were asked to position the needle tip on or into the imitation vessels and to avoid deeper penetration by using an agar tissue phantom with ultrasound guidance.

[Ischemic Changes in the Electrocardiogram and Circulatory Collapse Accompanied by Severe Anemia Owing to the Delay of Red Blood Cell Concentrate Transfusion in Two Patients with Intraoperative Massive Bleeding].

We present two patients developing intraoperative massive bleeding and showed ischemic changes in the electrocardiogram and circulatory collapse accompanied by severe anemia owing to the delay of red blood cell concentrate transfusion. One patient underwent hepatectomy and the other pancreaticoduodenectomy. Their lowest hemoglobin concentration was around 2 g x dl(-1), and they showed ischemic changes in the electrocardiogram and severe decreases in blood pressure.

[Effects of low dose colforsin daropate hydrochloride in patients undergoing off-pump coronary artery bypass grafting].

Background: We evaluated retrospectively the effectiveness of low dose colforsin daropate hydrochloride (CDH) in 12 patients undergoing off-pump coronary artery bypass grafting (CABG).

Methods: Low dose CDH was administered intravenously at a rate of 0.05-0.

[Present state of guidelines for perioperative management of deep vein thrombosis and pulmonary embolism in Japan].

To clarify the present state of local institutional guideline for perioperative deep thrombosis and pulmonary embolism in individual hospitals, a questionnaire was sent to anesthesia departments in Japan. According to the replies, 82 hospitals have original guidelines. Forty of them reported the contents of their guidelines.

[Evaluation of the different doses of olprinone for continuous infusion after cardiopulmonary bypass for coronary artery bypass surgery].

Background: We evaluated the hemodynamic efficacy of combined cathecholamine and three different continuous infusion doses of olprinone (0.05, 0.1, 0.

[Incidence and duration of hoarseness following endotracheal intubation].

The incidence and duration of hoarseness following tracheal intubation with general anesthesia were studied retrospectively from November 1998 to October 2000 in postanesthetic clinic of Nara Medical University. Total number of patients was 3977 and 37.1% of them complained of hoarseness.

[Paradoxical embolism during MIDCAB surgery].

A 36-year-old woman underwent MIDCAB surgery. During the exposure of LAD, the right ventricular wall was injured. The bleeding was controlled by compression.

[Effects of amrinone in patients undergoing off-pump coronary artery bypass grafting].

We evaluated the effect of amrinone in 41 patients undergoing off-pump coronary artery bypass grafting(CABG) retrospectively. Amrinone was intravenously administered at the rate of 5 mcg.kg-1.

[Sevoflurane can induce rhabdomyolysis in Duchenne's muscular dystrophy].

Rhabdomyolysis is one of the perioperative complications in patients with Duchenne's muscular dystrophy (DMD). It has been suggested that sevoflurane can be used safely for anesthesia in patients with DMD. In this report, we describe a case with DMD who received anesthesia with sevoflurane, in which rhabdomyolysis developed postoperatively.
