Smart infusion pump technology is a mainstay in health care, and the integration and use of those pumps is crucial for patient safety. An institution purchasing smart infusion pumps has the ability to trial the various vendors before purchase, however literature that documents a conversion from one pump to another is lacking. This article describes the conversion from one smart infusion pump platform to another at a government institution and a large multisite facility. The differences in 2 smart infusion pumps are described as well as lessons learned following the conversion in both organizations...

Advances in microscopic three-dimensional (µ3D) printing provide a means to microfabricate an almost limitless range of arbitrary geometries, offering new opportunities to rapidly prototype complex architectures for microfluidic and cellular applications. Such 3D lithographic capabilities present the tantalizing prospect for engineering micromechanical components - for example, pumps and valves - for cellular environments comprised of smart materials whose size, shape, permeability, stiffness, and other attributes might be modified in real time to precisely manipulate ultra-low-volume samples...

Andrew A M Ibey, Derek Andrews, Barb Ferreira
The authors present a case in which a physical anomaly with an infusion pump resulted in an unforeseen fault that the nurse's attempts to resolve unknowingly exacerbated. This case study presents the first report in the literature to detail the difficulty in recreating a patient safety event using smart pump logs, support server continuous quality improvement (CQI) data, and the drug order entry system to elucidate the clinical scenario. A 75-year-old male patient presented to a major teaching hospital and was admitted to the intensive care unit (ICU) with a massive gastrointestinal bleed and myocardial infarction, then stabilized...

Simon A Bello, Sharad Malavade, Christopher L Passaglia
Animal models of ocular hypertension are important for glaucoma research but come with experimental costs. Available methods of intraocular pressure (IOP) elevation are not always successful, the amplitude and time course of IOP changes are unpredictable and irreversible, and IOP measurement by tonometry is laborious. Here we present a novel system for monitoring and controlling IOP without these limitations. It consists of a cannula implanted in the anterior chamber of the eye, a pressure sensor that continually measures IOP, and a bidirectional pump driven by control circuitry that can infuse or withdraw fluid to hold IOP at user-desired levels...

Fazil E Uslu, Kerem Pekkan
Hydrodynamic performance of the marine mussel, Mytilus galloprovincialis, is studied with time-resolved particle image velocimetry. We evaluated inhalant flow, exhalant jet flow, suction performance and flow control capabilities of the mussels quantitatively. Inhalant flow structures of mussels are measured at the coronal plane for the first time in literature. Nutrient fluid is convected into the mussel by three-dimensional sink flow. Inhalant velocity reaches its highest magnitude inside the mussel mantle while it is accelerating outward from the mussels...

C E Morris, B Joos
Sick excitable cells (ie, Nav channel-expressing cells injured by trauma, ischemia, inflammatory, and other conditions) typically exhibit "acquired sodium channelopathies" which, we argue, reflect bleb-damaged membranes rendering their Nav channels "leaky." The situation is excitotoxic because untreated Nav leak exacerbates bleb damage. Fast Nav inactivation (a voltage-independent process) is so tightly coupled, kinetically speaking, to the inherently voltage-dependent process of fast activation that when bleb damage accelerates and thus left-shifts macroscopic fast activation, fast inactivation accelerates to the same extent...

BACKGROUND: To reduce complications during coronary artery bypass grafting (CABG) off-pump CABG was introduced; however, results have been mixed. The aim of this work was to conduct a systematic review and meta-analysis of off-pump vs. on-pump CABG. METHODS: To identify potential studies systematic searches were carried out using various databases. The search strategy included the key concepts of "cardiopulmonary bypass" AND "coronary artery bypass grafting" AND "off pump"...

AIM: Wide scale implementation of paediatric standardised concentration infusions (SCIs) and the use of smart pump technology has been slow despite international safety agency recommendations. Implementation rates in European hospitals fall far below those in the United States, where for the last decade accreditation has been linked to implementation.1 2 Multidisciplinary collaboration is essential, with pharmacy input and the creation of a smart pump drug library recognised as often being limiting, yet crucial factors, to implementation...

A smart multi-pipette for hand-held operation of microfluidic devices is presented and applied to cytotoxicity assays and micro-droplet generation. This method enables a continuous-flow and accurate pumping simply by pushing the plunger of the smart multi-pipette, thereby obviating the need for auxiliary equipment and special expertise in microfluidics. We applied the smart multi-pipette to a cytotoxicity assay using a gradient-generating device and water droplet generation using a T-junction device. In combination with general microfluidic devices, the smart multi-pipette enables the devices to successfully perform their own functions...

Controllable liquid transport on surface is expected to occur by manipulating the gradient of surface tension/Laplace pressure and external stimuli, which has been intensively studied on solid or liquid interface. However, it still faces challenges of slow response rate, and uncontrollable transport speed and direction. Here, we demonstrate fast responsive and controllable liquid transport on a smart magnetic fluid/nanoarray interface, i.e., a composite interface, via modulation of an external magnetic field...

Health IT is becoming an increasingly powerful tool for improving medication safety. While errors may happen at all stages of the medication process, different tools have been developed to support the prescribing process (e.g. computerized prescribing with decision support), the dispensing process (e.g. barcoding or automated dispensing and unit-dose systems), or the administration process (e.g. electronic medication administration records and smart pumps). Health IT can reduce medication error and preventable adverse drug event rates by increasing documentation quality and transparency, enhancing accuracy and correctness of the medication process, and supporting information exchange and interlinking different stages of the medication process...

Regulation of Ca(2+) transport is vital in physiological processes, including lactation, proliferation and apoptosis. The plasmalemmal Ca(2+) pump isoform 2 (PMCA2) a calcium ion efflux pump, was the first protein identified to be crucial in the transport of Ca(2+) ions into milk during lactation in mice. In these studies we show that PMCA2 is also expressed in human epithelia undergoing lactational remodeling and also report strong PMCA2 staining on apical membranes of luminal epithelia in approximately 9% of human breast cancers we assessed...

The incidence of diabetes is increasing at an unprecedented pace and has become a serious health concern worldwide during the last two decades. Despite this, adequate glycemic control using an artificial pancreas has not been established, although the 21st century has seen rapid developments in this area. Herein, we review current topics in glycemic control for both the wearable artificial pancreas for type 1 and type 2 diabetic patients and the bedside artificial pancreas for surgical diabetic patients. In type 1 diabetic patients, nocturnal hypoglycemia associated with insulin therapy remains a serious problem that could be addressed by the recent development of a wearable artificial pancreas...

The enhancement of green upconverted emission from the Er<sup>3+</sup>/Yb<sup>3+</sup> co-doped (Pb,La)(Zr,Ti)O<sub>3</sub> ceramic powder under a pumping light with a wavelength of 1480 nm was observed to be greater than 30 times that from the bulk of the same sample. Weak localization of light supported by the spatial profile of scattered light facilitated the three-photon process contributing to stronger green upconverted emission. Significant backward light amplification was also observed and studied in detail...

BACKGROUND: Changeovers of norepinephrine infusion pumps (CNIPs) frequently lead to haemodynamic instability. The aim of this study was to identify risk factors for haemodynamic instability associated with CNIP, independent of the method used to perform the relay. METHODS: We performed a prospective study, in a university-affiliated intensive care unit. Over a 1-year period, all adult patients who had at least one CNIP were included. CNIPs were automatically performed using smart pumps, in accordance with a standardised protocol...
