Abstract This study compared a field versus reference laboratory technique for extracting (syringe vs. centrifuge) and analyzing sweat [Na(+)] and [K(+)] (compact Horiba B-722 and B-731, HORIBA vs. ion chromatography, HPLC) collected with regional absorbent patches during exercise in a hot-humid environment. Sweat samples were collected from seven anatomical sites on 30 athletes during 1-h cycl...

PURPOSE To describe an intravitreal injection technique using a commercially available 29-gauge insulin needle syringe (29GN syringe) and a 21-gauge (G) needle, comparing compound waste associated with this technique application and the one described in ranibizumab (Lucentis) kit instructions. METHODS Ten 0.3 ml doses of distilled water were aspirated using the 29GN syringe and 21G needle (PT...

OBJECTIVE Oral syringes are the preferred method for delivering paediatric enteral drugs; however, little is known about factors affecting accuracy, particularly at volumes <5 mL. We investigated volumetric accuracy for enteral syringes, using commercially available liquid drug formulations with various physicochemical properties at clinically relevant volumes. DESIGN In vitro experiment. I...

INTRODUCTION We evaluated the effect of different syringe volume, needle size and sample volume on blood gas analysis in syringes washed with heparin. MATERIALS AND METHODS In this multi-step experimental study, percent dilution ratios (PDRs) and final heparin concentrations (FHCs) were calculated by gravimetric method for determining the effect of syringe volume (1, 2, 5 and 10 mL), needle s...

In the fall of 2008, light was shed on the practice of syringe re-use occurring in western Canada (Government of Alberta, 2009). In this situation, syringes had been re-used between patients to administer sedating medication through patient intravenous (IV) lines (Government of Alberta, 2009). Later it was reported that other incidents of syringe re-use had occurred in Canada (CBC News-Edmonton...

Selection of high-quality sperm is crucial to assisted reproduction. However, conventional clinical methods for selection are manual and prone operator errors. This article presents ‘sperm syringe', a scalable technology that mimics the highly parallelized 3D process in vivo via network 560 microchannels select sperm. Sperm syringe retrieves more than 41% healthy from initial sample under 15 mi...
