We report, for the first time, the concept and generation of a novel Fresnel hologram called the digital binary mask programmable hologram (BMPH). A BMPH is comprised of a static, high resolution binary grating that is overlaid with a lower resolution binary mask. The reconstructed image of the BMPH can be programmed to approximate a target image (including both intensity and depth information)...

A new illumination system for mask aligner lithography is presented. The illumination system uses two subsequent microlens-based Köhler integrators. The second Köhler integrator is located in the Fourier plane of the first. The new illumination system uncouples the illumination light from the light source and provides excellent uniformity of the light irradiance and the angular spectrum. Spatia...

Some providers advocate using laryngeal mask airways (LMAs) for procedures performed in the prone position to meet the demands of quicker operating room turnover time requirements, staffing reductions and the desire to expedite patient recovery in the postoperative period. We provide an update to a 2010 systemic review examining the use of LMAs in patients in the prone position. Six peer-review...

AIM: Sedation regimens for toddlers and preschoolers are still open for further studies. Propofol is rapidly finding its way into medical routine. The aim of this pilot study was to re-evaluate the need for sedation in young children and to further investigate the use of propofol as an intravenous agent combined with the use of a flexible laryngeal mask for treatment of the youngest group of de...

IMPLICATIONS The ProSeal and classic laryngeal mask airways are equally effective ventilatory devices in healthy female patients at tidal volumes of 8 and 12 mL/kg with the cuff semi- or fully inflated, but leakage of small volumes of air from the mouth occurs more frequently with the laryngeal mask airway.

Received: February 11, 2016 Revised: June 24, 2016 Accepted: June 24, 2016 Abstract: Background: Supraglottic airway devices (SADs) are very useful airway adjunct in managing anticipated and unanticipated difficult airway and can be used as a ventilating aid and as a conduit for tracheal intubation. The new versions of SADs like i-gel and intubating laryngeal mask airway (ILMA), have advantage ...

OBJECTIVE To compare the ability of UK paramedics to intubate a simulated difficult airway using a Mackintosh laryngoscope versus an intubating laryngeal mask airway (ILMA). METHOD/DESIGN A randomised controlled trial. RESULTS 100% of the paramedics were able to intubate a simulated difficult airway using the ILMA versus 0% of those using the Mackintosh laryngoscope. CONCLUSIONS This stud...

The laryngeal mask airway (LMA) is an important new tool for managing the emergency airway. In a variety of emergency situations, the LMA may be considered instead of the face mask or the endotracheal tube. Furthermore, the LMA can be used as an aid to intubation and as a bridge to more secure means to control the airway. The primary risk with the LMA is aspiration of gastric contents. Anesthet...
