Immediate screening method for predicting the necessity of massive transfusions in trauma patients: a retrospective single-center study.

Background: Hemostatic resuscitation might improve the survival of severely injured trauma patients. Our objective was to establish a simplified screening system for determining the necessity of massive transfusions (MT) at an early stage in trauma cases.

Methods: We retrospectively analyzed the cases of trauma patients who had been transported to our institution between November 2011 and October 2013.

Mean lung pressure during adult high-frequency oscillatory ventilation: an experimental study using a lung model.

In adult high-frequency oscillatory ventilation (HFOV), stroke volume (SV) and mean lung pressure (PLung) are important for lung protection. We measured the airway pressure at the Y-piece and the lung pressure during HFOV using a lung model and HFOV ventilators for adults (R100 and 3100B). The lung model was made of a 20-liter, airtight rigid plastic container (adiabatic compliance: 19.

Oxygen supersaturated fluid using fine micro/nanobubbles.

Microbubbles show peculiar properties, such as shrinking collapse, long lifetime, high gas solubility, negative electric charge, and free radical production. Fluids supersaturated with various gases can be easily generated using microbubbles. Oxygen microbubble fluid can be very useful for oxygen delivery to hypoxic tissues.

Evaluating the need for and effect of percutaneous transluminal angioplasty on arteriovenous fistulas by using total recirculation rate per dialysis session ("clearance gap").

The functioning of an arteriovenous fistula (AVF) used for vascular access during hemodialysis has been assessed mainly by dilution methods. Although these techniques indicate the immediate recirculation rate, the results obtained may not correlate with Kt/V. In contrast, the clearance gap (CL-Gap) method provides the total recirculation rate per dialysis session and correlates well with Kt/V.

Overheated and melted intracranial pressure transducer as cause of thermal brain injury during magnetic resonance imaging: case report.

Magnetic resonance imaging is used with increasing frequency to provide accurate clinical information in cases of acute brain injury, and it is important to ensure that intracranial pressure (ICP) monitoring devices are both safe and accurate inside the MRI suite. A rare case of thermal brain injury during MRI associated with an overheated ICP transducer is reported. This 20-year-old man had sustained a severe contusion of the right temporal and parietal lobes during a motor vehicle accident.

Humidification of base flow gas during adult high-frequency oscillatory ventilation: an experimental study using a lung model.

In adult high-frequency oscillatory ventilation (HFOV) with an R100 artificial ventilator, exhaled gas from patient's lung may warm the temperature probe and thereby disturb the humidification of base flow (BF) gas. We measured the humidity of BF gas during HFOV with frequencies of 6, 8 and 10 Hz, maximum stroke volumes (SV) of 285, 205, and 160 ml at the respective frequencies, and, BFs of 20, 30, 40 l/min using an original lung model. The R100 device was equipped with a heated humidifier, Hummax Ⅱ, consisting of a porous hollow fiber in circuit.

Picosecond master-oscillator, power-amplifier system based on a mixed vanadate phase conjugate bounce amplifier.

We demonstrate a high average power approximately 4 ps output from a phase conjugate laser system based on a diode-side-pumped Nd:Gd(0.6)Y(0.4)VO(4) bounce amplifier.
