Using CUS Words in the NICU
Authors: Simons Sherri Lee
Published: November 2011

THE NATIONAL AERONAUTICS AND Space Administration (NASA) has been known for having some of the best employees in various engineering and science disciplines over the years. NASA’s collective accomplishments and cutting-edge technology made it possible for humankind to explore the moon and outer space, a feat once thought impossible. Yet, despite all of NASA’s accomplishments, on February 1, 2003, seven astronauts died when the Columbia incinerated on reentry into Earth’s atmosphere. A key contributor to that tragedy was a culture that fostered ineffective communication of critical safety information and stifled professional differences of opinion.1,2
Prevention of Nasal Injuries Secondary to NCPAP Application in the ELBW Infant
Authors: Squires Amanda Jayne , Hyndman Marilyn
Published: November 2011

Improved technology and management approaches that have reduced bronchopulmonary dysplasia (BPD) have decreased mortality and morbidity in extremely low birth weight (ELBW) infants. Early extubation to nasal continuous positive airway pressure (NCPAP) decreases the complications associated with long-term oral/nasal endotracheal intubation, including BPD, ventilatorassociated pneumonia, volutrauma, subglottic stenosis, oral palatal grooves, and nasal septum erosion. Research and anecdotal evidence have shown that iatrogenic injuries to the nose also occur with extended time on NCPAP. Research observing associations between the patient interface and nasal injury has shown duration of therapy to be the most significant risk factor. Immature skin and developing nasal structures place ELBW infants at increased risk for injury. The challenge for NICU caregivers is maintaining the ELBW infant on NCPAP for extended periods without nasal injury. Appropriate protocols, practice guidelines, and staff education can decrease these injuries.
Blood Gas Analysis and the Fundamentals of Acid-Base Balance
Authors: Farmand Mary
Published: November 2011

UNDERSTANDING BLOOD GAS values and acid-base balance are fundamental skills of neonatal nursing. This is because, in the NICU, blood gases are probably ordered more than any other laboratory test. The bedside nurse not only obtains the specimen, but is also crucially involved in interpreting the results because blood gases cannot stand alone; they need to be evaluated in the context of the entire clinical picture. This article provides basic information on the components of a blood gas, acid-base balance, as well as a systematic approach to blood gas analysis.

In the November/December 2008 issue of Neonatal Network, a feeding care map for breastfeeding ELBW infants was presented by Dougherty and Luther. The aim of this document was described as providing caregivers with an instrument for assisting mothers in optimizing breast milk production, providing them with realistic expectations, and enhancing their chances of establishing breastfeeding. The authors must be commended for their systematic approach to this very important aspect of neonatal intensive care. However, the article left me very concerned about several crucial requirements that need to be met in the formulation of clinical guidelines.
Are You an Advocate for Your Patient?
Authors: Fraser Debbie
Published: November 2011

ADVOCACY HAS LONG BEEN DESCRIBED AS AN INHERENT PART of our role as nurses. Who better to speak for, or support patients and their families than nurses? For neonatal nurses this is especially true. Patient vulnerability is cited as a common reason that nurses take the role of an advocate.1 No population is more vulnerable than a sick or premature newborn, and, by extension, their parents.
Transthyretin (aka Prealbumin): Why Is It Part of TPN Labs?
Authors: Nash Patricia
Published: November 2011

AS IN OTHER NICUs, OUR PATIENTS on total parenteral nutrition (TPN) have routine labs done for monitoring. In our unit, these labs include electrolytes, hemoglobin, triglycerides, liver function studies, and transthyretin (TTR) (still called prealbumin). In polling the other neonatal nurse practitioners, I realized that none of us completely understood the utility of following the TTR level. That was the impetus for this column.
Helping NICU Families Through the Holidays

Staphylococcus aureusSepticemia with a Fatal Transmural Myocardial Infarction in a 27-Week-Gestation Twin Infant: A Case Study
Authors: Hines Amanda , Rawlins Patricia
Published: November 2011

Septicemia, one of the major causes of morbidity and mortality in the neonatal period, often has a rapid and fulminant course. Low-birth-weight infants with persistentStaphylococcus aureussepticemia, possibly associated with percutaneous central venous catheters, may develop metastatic infections including endocarditis with large vegetations. This article describes a neonate withS. aureusbacteremia that resolved with treatment who died secondary to decreased left ventricular function. At autopsy, organizing microthrombi were seen within both atria, the left ventricle, and the left coronary arterial system. Extensive infarcts were noted throughout the entire myocardium of the left ventricle. It was suspected, but not proven, that the thrombotic sequelae from septicemia caused this neonate’s death.
Ventricular Reservoir Punctures Performed by Nurses: An Improvement in Quality of Care
Authors: Brouwer Annemieke , Groenendaal Floris , van den Hoogen Agnes , de Vos Jannie , de Vries Linda
Published: November 2011

Management strategies in the treatment of infants with posthemorrhagic ventricular dilation include the placement of a ventricular reservoir. Traditionally, ventricular punctures of these reservoirs have been performed only by physicians. In the pilot project described in this article, we taught nursing staff to perform punctures of a cerebral ventricular reservoir in neonates with hydrocephalus to give nurses more control in their daily care of these infants.

All consecutive punctures performed between August 2006 and March 2007 (n = 302) were studied. The chart was reviewed for the infant’s state during the puncture, the caregiver who performed the puncture, and the timeliness of the puncture with respect to schedule and to infant state. During the day shift, there was no significant difference in timeliness, whether the puncture was performed by a physician, a nurse, a physician assistant (PA), or a nurse under the supervision of a physician. On the night shift, punctures were performed on schedule significantly more often when they were carried out by nurses (p>.001). This pilot project demonstrated that nurses can learn to perform cerebrospinal fluid removal from a ventricular reservoir. Because it increased the timeliness with which punctures were performed and gave nurses more control in planning rest periods for these infants, this policy change was judged a success.
When a Baby Dies: When Families Need You the Most
Authors: Discenza Deb
Published: November 2011

A NEONATAL NURSE SEES SOME truly stressful situations in the NICU. Day in and day out, infants are brought into the NICU, others are discharged to go home, and in between there are a lot of health care needs to tend to for each patient. Add to those demands caring for each patient’s family—helping them address the reality of their child’s special needs now and going forward. Although most nurses in the NICU love their jobs and thrive on the ever-changing environment, one of the most difficult tasks is likely working with the family of an infant who is dying. It is heartbreaking to see a child die and to watch family members go through such trauma. But you can help prepare grieving families for this stressful life event and support them so that they can handle it with dignity.

In the Critically Ill, Nothing-by-Mouth Infant, Would Enteral Administration of Simulated Amniotic Fluid Improve Feeding Tolerance Compared with the Current Practice of No Therapy? An Evidence-Based Review
Authors: Smith Caren G.
Published: November 2011

Necrotizing enterocolitis (NEC) can be a devastating disease in the NICU population. The current standard of practice of not providing enteral nutrition to the critically ill and the premature infant is thought to result in pathophysiologic changes of the gastrointestinal (GI) tract that may result in the development of NEC. Various methods of preventing or reducing the incidence of NEC in the NICU have been explored. One such method is the enteral administration of simulated amniotic fluid (SAF). This article compares, contrasts, and reviews the available evidence regarding the use of SAF feedings as a means of reducing GI tract changes associated with nothing-by-mouth (NPO) status.

Published: November 2011

The use of woody biomass feedstocks for bioenergy and bioproducts involves multiple sources of material that together create year round supplies. The main sources of woody biomass include residues from wood manufacturing industries, low value trees including logging slash in forests that are currently underutilized and dedicated short-rotation woody crops. Conceptually a ton of woody biomass feedstocks can replace a barrel of oil as the wood is processed (refined) through a biorefinery. As oil is refined only part of the barrel is used for liquid fuel, e.g., gasoline, while much of the carbon in oil is refined into higher value chemical products-carbon in woody biomass can be refined into the same value-added products.

Initial Efficacy of a Cardiac Rehabilitation Transition Program: Cardiac TRUST
Authors: Dolansky Mary A. , Zullo Melissa D. , Boxer Rebecca S. , Moore Shirley M.
Published: November 2011

The purpose of this pilot study was to test the initial efficacy, feasibility, and safety of a specially designed postacute care transitional rehabilitation intervention for cardiac patients. Cardiac Transitional Rehabilitation Using Self-Management Techniques (Cardiac TRUST) is a family-focused intervention that includes progressive low-intensity walking and education in self-management skills to facilitate recovery following a cardiac event. Using a randomized two-group design, exercise self-efficacy, steps walked, and participation in an outpatient cardiac rehabilitation (CR) program were compared in a sample of 38 older adults (17 Cardiac TRUST, 21 usual care). At discharge from postacute care, the intervention group trended toward higher levels of self-efficacy for exercise outcomes than the usual care group. During the 6 weeks following discharge, the intervention group had greater attendance in outpatient CR and a trend toward more steps walked during the first week. The feasibility of the intervention was better for the home health care participants than for those in the skilled nursing facility. The provision of CR during postacute care has the potential to bridge the gap in transitional services from hospitalization to outpatient CR for these patients at high risk for future cardiac events. Further evidence of the efficacy of Cardiac TRUST is warranted.

Authors: Roos Richard , Gorgolewski Dr. Mark
Published: November 2011

LEED Canada for Existing Buildings: Operations and Maintenance (LEED Canada EB:O&M) and Building Owners and Managers Association's Building Environmental Standards (BOMA BESt) are complex green rating systems that offer owners, managers, consultants, and tenants distinct value propositions for existing buildings. Upon close examination, significant variations between the systems are evident in certification process, cost, rigor, engagement, marketing, accessibility, transparency, management, and program philosophy. Despite the many differences between the systems, they are often seen to be complementary programs and are sometimes used in tandem for the same building. This paper reports on a survey of the industry perceptions of the value and strengths of the LEED Canada EB:O&M and BOMA BESt rating systems with respect to the above criteria. As a result of the fundamentally different nature of the programs, preferences for LEED Canada EB:O&M and BOMA BESt are determined by stakeholder values and the programs are used for a variety of reasons.

Antibiotic Utilization for Surgical Prophylaxis in a Tertiary Care Teaching Rural Hospital
Authors: Shah Amit , Gajjar Bharat , Shankar Ravi
Published: November 2011

Rational antibiotic prophylaxis reduces the incidence of surgical wound infection. Improper antibiotic prophylaxis leads to excessive surgical wound infection and increased drug resistance. There is an urgent need to establish and implement antibiotic policy but it cannot be done if baseline data is not available. In this study, the authors gathered baseline data about the pattern of surgical antibiotic prophylaxis in their institute. They found that most of the perioperative use of antibiotics was not as per standard guidelines in terms of choice of antibiotics and total duration of treatment. Interventions are warranted to promote the development, dissemination, and adoption of evidence-based guidelines for antibiotic surgical prophylaxis.
Towards a Mission-Critical Ambient Intelligent Fire Victims Assistance System
Authors: Feng Ling , Li Yuanping , Qiao Lin
Published: November 2011

While various ambient computing and intelligence techniques have been used to assist human beings in different aspects of their daily lives and work, this paper investigates potential ambient intelligence support in mission-critical scenarios such as firefighting. The paper reviews state-of-the-art ubiquitous techniques and tools assisting firefighting. Based upon these great research results, the authors then report the design and implementation of an ambient intelligent fire victims assistance application. By sensing the physical environment and occupants in a fire building, the system suggests the safest and fastest route along which the building occupants could evacuate; and when escaping from the building is not possible, the system tries to calm down and inform the trapped ones an action list. The channels to convey the guide assistance include traditional lights, speakers, and occupants’ mobile phones (if existing). The empirical experiments show that ambient intelligence in such a fire response guide can help improve the egress time performance of building occupants. The presented ambient smart fire victims’ assistance system is supposed to work at an early stage of fire in a building. As a complement of existing firefighting techniques, it still faces a number of open questions to be resolved in the future.
An Effective Hybrid Semi-Parametric Regression Strategy for Rainfall Forecasting Combining Linear and Nonlinear Regression
Authors: Wu Jiansheng
Published: November 2011

Rainfall forecasting is an important research topic in disaster prevention and reduction. The characteristic of rainfall involves a rather complex systematic dynamics under the influence of different meteorological factors, including linear and nonlinear pattern. Recently, many approaches to improve forecasting accuracy have been introduced. Artificial neural network (ANN), which performs a nonlinear mapping between inputs and outputs, has played a crucial role in forecasting rainfall data. In this paper, an effective hybrid semi-parametric regression ensemble (SRE) model is presented for rainfall forecasting. In this model, three linear regression models are used to capture rainfall linear characteristics and three nonlinear regression models based on ANN are able to capture rainfall nonlinear characteristics. The semi-parametric regression is used for ensemble model based on the principal component analysis technique. Empirical results reveal that the prediction using the SRE model is generally better than those obtained using other models in terms of the same evaluation measurements. The SRE model proposed in this paper can be used as a promising alternative forecasting tool for rainfall to achieve greater forecasting accuracy and improve prediction quality.
Constructing and Utilizing Video Ontology for Accurate and Fast Retrieval
Authors: Shirahama Kimiaki , Uehara Kuniaki
Published: November 2011

This paper examines video retrieval based on Query-By-Example (QBE) approach, where shots relevant to a query are retrieved from large-scale video data based on their similarity to example shots. This involves two crucial problems: The first is that similarity in features does not necessarily imply similarity in semantic content. The second problem is an expensive computational cost to compute the similarity of a huge number of shots to example shots. The authors have developed a method that can filter a large number of shots irrelevant to a query, based on a video ontology that is knowledge base about concepts displayed in a shot. The method utilizes various concept relationships (e.g., generalization/specialization, sibling, part-of, and co-occurrence) defined in the video ontology. In addition, although the video ontology assumes that shots are accurately annotated with concepts, accurate annotation is difficult due to the diversity of forms and appearances of the concepts. Dempster-Shafer theory is used to account the uncertainty in determining the relevance of a shot based on inaccurate annotation of this shot. Experimental results on TRECVID 2009 video data validate the effectiveness of the method.

Published: November 2011

In order to improve the experimental evidence of hotoinitiator, the effects of various dose of photoinitiator on mechanical properties of nanohydroxyapatite composite were investigated. According to the light initiating system, CQ and DMAEMA accounted for 0.8wt％, 1.0wt％, 1.2wt％ of total resin matrix, respectively. And then NHA processed by KH-570 was mixed with resin matrix in the ratio of 55:45. Then three groups （A, B, and C） of light-cured nanohydroxyapatite composites were prepared. Karuisima composite resin was used as control group D. The cured depth, compressive strength, and flexural strength were determined in each group. The results showed that as the ratio of photoinitiator increased, the cured depth increased, while the mechanical function declined. In group B, there were no significant differences in compressive strength, and flexural strength as compared with control group,P>0.05. It is suggested that the quantity of CQ and DMAEMA in resin matrix were 1.0wt% respectively, the new light-cured nanohydroxyapatite composite has good qualities in both cured depth and mechanical property.

Authors: Mu Zhen Wei , Zhang Zhi Yan
Published: November 2011

An experiment of a single particle movement in vertical spiral rectangular duct has investigated with the aim to study the rotational Coriolis force based on kinetic model of single granular. The results indicate that: the dominant forces upon the particle are the centrifugal force, rotational Coriolis force, effectual gravity and drag force. There is exponential relation between λ and ζ, where λ stand for the ratio of tangential velocity of particle and water velocity, ζ stand for the ratio of rotational the Coriolis force and the centrifugal force. The probability of rotational Coriolis force and centrifugal force in the same order of magnitude is three-quarter. Therefore, the rotational Coriolis force should not be ignored on force analysis of a particle in small-scale rotational flow.
Effects of Sb2O3 Addition on Dielectric Properties of Barium Strontium Titanate Based Ceramics
Authors: Zhang Chen , Qu Yuan Fang
Published: November 2011

The dielectric properties of Sb2O3-doped (Ba0.732Sr0.26Nd0.008)TiO3.004ceramics fabricated by conventional solid state method were investigated. The structure was identified by X-ray diffraction method and scanning electron microscope was also employed to observe the surface morphologies. It is confirmed that Sb2O3-doped (Ba0.732Sr0.26Nd0.008)TiO3.004ceramics exhibit perovskite structure and with increasing Sb2O3content Ba6Ti17O40(space group C2/c (15) ) forms as a secondary phase. The experimental results reveal that the addition of Sb2O3into (Ba0.732Sr0.26Nd0.008)TiO3.004ceramics reduce the dielectric constant and Curie temperature due to the substitution for A/B-sites with Sb3+ions. The standing voltage increases with increasing Sb2O3content while the dielectric loss and resistivity initially decrease and then increase with the increase of Sb2O3concentration. The temperature dependence of dielectric properties at different frequencies was studied as well. It indicates that the tetragonal-cubic phase transition peak is suppressed as the Sb2O3content increases and the peak value reduces with the increase of frequency.

Authors: Hsieh Kuen Chang , Chen Kuen Tsann , Kanjanaphachoat Choatponag , Yeh Ching Wen , Chen Yu Yawn
Published: November 2011

In this study, a finite element method was used to study force transducer anti-deviated load characteristics. Through the changes produced by different sizes of force transducer finite element models, modal analyses in linear static analyses of different biased loadings were applied to perform cross-validation. The results indicate that force transducers with same strain output but with high torsional stiffness have better anti-deviated load capacity. Increasing the torsional stiffness of the force transducer could reduce the loss of precision due to biased loading.

Published: November 2011

Owing to fluid characteristics of hydraulic structure seismic response, analysis method of this problem considering fluid-solid interaction is pointed out. And seismic response of vertical plate in the water was taken as an example to show how to solve this fluid-solid interaction system and analysis the features of it. In the analysis, effects of wave frequency and water depth were considered. The results indicate that incompressible fluid model based on Arbitrary Largrange Elurian description is enough to simulate motion of fluid domain and insure computing convergence in the analysis. It also shows that peak value of structure dynamic response is larger as the consideration of fluid-solid interaction. Water depth has great effect on fluid-solid interaction and has clear nonlinear feature.

Geometrical parameters of composite laminated plates in engineering structure tend to have stochastic properties. It would be very significant on how to study the random parameter laminated plates, and the parameters optimization analysis of mechanical properties, influencing on the correctly-estimated reliability of structure design. Based on the classical theory advocated by Kirchhoff, which indicates that with spline finite element method, cubic b-spline function constitutes the spline to antisymmetry multi-layer angle laid against laminated plates on the three independent displacement and the interpolation which can deduce composite laminated plate stiffness matrix, quality array type, the damping array type, and the dynamic equations of laminates is derived by Lagrange equation and a characteristic equation established by Rayleigh-Ritz theory.

Published: November 2011

On the basis of the differential equation governing small flexure of thin elastic vibrating plate, the formula for calculating the phase velocity and group velocity of ice sheet wave propagation under the air cushion load is induced. The minimum of the phase velocity is the critical speed about ice breaking by air cushion vehicle (ACV). If ACV moves at the critical speed, the energy causing the deformation of ice sheet is concentrated constantly, thus the amplitude of the wave is enlarged enough to break the ice by resonance.
