Limited hydration may reduce intraoperative blood loss in retropubic radical prostatectomy.

Retropubic radical prostatectomy (RRP) may involve major intraoperative blood loss. This study focuses on how limited intraoperative hydration, especially in the early part of the surgery, affects the total blood loss. Fifteen prostate cancer patients were enrolled in this study in which the RRPs were performed by a single surgeon with limited (no more than 1500 ml as a rule) intraoperative hydration in the first 2 hours of the surgery when ligation of intrapelvic lymph node, dorsal vein complex (DVC), neurovascular bundle (NVB) and cut of urethra are assumed to be finished, and were compared with the control group in which no intervention of hydration was undertaken.

Angle-resolved photoemission spectroscopy of the antiferromagnetic superconductor Nd1.87Ce0.13CuO4: anisotropic spin-correlation gap, pseudogap, and the induced quasiparticle mass enhancement.

We performed high-resolution angle-resolved photoemission spectroscopy on Nd1.87Ce0.13CuO4, which is located at the boundary of the antiferromagnetic (AF) and the superconducting phase.

Square vortex lattice at anomalously low magnetic fields in electron-doped Nd1.85Ce0.15CuO4.

We report here on the first direct observations of the vortex lattice in the bulk of electron-doped Nd1.85Ce0.15CuO4 single crystals.

Commensurate spin dynamics in the superconducting state of an electron-doped cuprate superconductor.

We report neutron scattering studies on two single crystal samples of the electron-doped (n-type) superconducting (SC) cuprate Nd2-xCexCuO4 (x=0.15) with T(c)=18 and 25 K. Unlike the hole-doped (p-type) SC cuprates, where incommensurate magnetic fluctuations commonly exist, the n-type cuprate shows commensurate magnetic fluctuations at the tetragonal (1/2 1/2 0) reciprocal points both in the SC and in the normal state.

[Persistent neurological deficit and adhesive arachnoiditis following spinal anesthesia with bupivacaine containing preservatives].

A 75 year-old female with osteoarthritis of bilateral knee joints was scheduled for right total knee replacement. Her medical history included coronary artery disease, bronchial asthma, and previous surgery of lumbar laminectomy, but she had no neurological deficit before the operation. A 22-gauge spinal needle was inserted at the L 4-5 level and 4 ml of 0.

[Permanent paraplegia following epidural and general anesthesia: two case reports].

Case-1: A 72-year-old woman with no past neurological history was scheduled for a rectum resection under general combined with epidural anesthesia. An epidural catheter was introduced at T11-12 interspace without any difficulties. During the operation, she had hypotensive episode needing dopamine, but waked up from anesthesia without any event.

Thyrotropin-releasing hormone produces different hemodynamic effects in vegetative and brain-dead patients.

To define a mechanism for the pressor effects of thyrotropin-releasing hormone (TRH), we evaluated changes in mean blood pressure (MBP) when a synthetic form of TRH (0.1 mg/kg, i.v.

[Changes in heart rate during and after enflurane-nitrous oxide anesthesia].

Changes in heart rate of 21 patients who received enflurane-nitrous oxide anesthesia were studied. They had no cardiac, pulmonary, nervous system and endocrine diseases. We measured coefficient of variation of R-R intervals (CV) and power spectrum of heart rate fluctuation in 6 periods, (1) control phase (the day before operation), (2) during operation under enflurane-nitrous oxide anesthesia, (3) ten minutes after endotracheal extubation, (4) sixty minutes after arrival in the recovery room, (5) the next morning and (6) the next evening.

[Anesthesia for surgical intervention in recurrent pneumothorax in a patient with one lung].

A 56 year old man was scheduled for partial resection of the right lung because of many spontaneous pneumothorax episodes. He had received left pneumonectomy for pulmonary tuberculosis and his respiratory function was severely depressed. During anesthesia, pulse oximetry, pulmonary arterial pressure monitoring, pulmonary arterial oximetry in addition to ordinary systemic arterial pressure and electrocardiogram monitoring were performed.

[Anesthetic management of a patient with dermatomyositis--clinical observation of the effect of muscle relaxants].

A 58 year old woman suffering from dermatomyositis underwent elective surgery for spinal caries. Concerning the anesthetic management of patient suffering from dermatomyositis, there is little information on the appropriate use of muscle relaxants. It is generally suspected that the patient is sensitive to nondepolarizing muscle relaxants.

Detection of air embolism by transesophageal echocardiography.

In this study transesophageal echocardiography was utilized for detecting air embolism in dogs in the supine position and in patients undergoing neurosurgery in the sitting position. In dogs, the threshold dose of venous air for detection was determined using either a bolus injection or continuous infusion of air via the jugular vein for up to three minutes. The ability to detect air in the aorta also was determined by a bolus injection into the left ventricular via an arterial catheter.
