Abstract
Near-Infrared (NIR) light emitting metal halides are emerging as a new generation of optical materials owing to their appealing features, which include low-cost synthesis, solution processability, and adjustable optical properties. NIR-emitting perovskite-based light-emitting diodes (LEDs) have reached an external quantum efficiency (EQE) of over 20% and a device stability of over 10,000 h. Such results have sparked an interest in exploring new NIR metal halide emitters. In this review, several different types of NIR-emitting metal halides, including lead/tin bromide/iodide perovskites, lanthanide ions doped/based metal halides, double perovskites, low dimensional hybrid and Bi3+/Sb3+/Cr3+ doped metal halides, are summarized, and their recent advancement is assessed. The characteristics and mechanisms of narrow-band or broadband NIR luminescence in all these materials are discussed in detail. Also, the various applications of NIR-emitting metal halides are highlighted and an outlook for the field is provided.

Abstract
OBJECTIVES The study focused on developing a reliable real-time venous localization, identification, and visualization framework based upon deep learning (DL) self-parametrized Convolution Neural Network (CNN) algorithm for segmentation of the venous map for both lower and upper limb dataset acquired under unconstrained conditions using near-infrared (NIR) imaging setup, specifically to assist vascular surgeons during venipuncture, vascular surgeries, or Chronic Venous Disease (CVD) treatments. METHODS A portable image acquisition setup has been designed to collect venous data (upper and lower extremities) from 72 subjects. A manually annotated image dataset was used to train and compare the performance of existing well-known CNN-based architectures such as ResNet and VGGNet with self-parameterized U-Net, improving automated vein segmentation and visualization. RESULTS Experimental results indicated that self-parameterized U-Net performs better at segmenting the unconstrained dataset in comparison with conventional CNN feature-based learning models, with a Dice score of 0.58 and displaying 96.7 % accuracy for real-time vein visualization, making it appropriate to locate veins in real-time under unconstrained conditions. CONCLUSIONS Self-parameterized U-Net for vein segmentation and visualization has the potential to reduce risks associated with traditional venipuncture or CVD treatments by outperforming conventional CNN architectures, providing vascular assistance, and improving patient care and treatment outcomes.

Abstract
Recent advances in Raman spectroscopy have shown great potential for non-invasive analyte sensing, but the lack of a standardized optical phantom for these measurements has hindered further progress. While many research groups have developed optical phantoms that mimic bulk optical absorption and scattering, these materials typically have strong Raman scattering, making it difficult to distinguish metabolite signals. As a result, solid tissue phantoms for spectroscopy have been limited to highly scattering tissues such as bones and calcifications, and metabolite sensing has been primarily performed using liquid tissue phantoms. To address this issue, we have developed a layered skin-mimetic phantom that can support metabolite sensing through Raman spectroscopy. Our approach incorporates millifluidic vasculature that mimics blood vessels to allow for diffusion akin to metabolite diffusion in the skin. Furthermore, our skin phantoms are mechanically mimetic, providing an ideal model for development of minimally invasive optical techniques. By providing a standardized platform for measuring metabolites, our approach has the potential to facilitate critical developments in spectroscopic techniques and improve our understanding of metabolite dynamics in vivo.

Abstract
HyperSpectral Imaging (HSI) plays a pivotal role in various fields, including medical diagnostics, where precise human vein detection is crucial. HyperSpectral (HS) image data are very large and can cause computational complexities. Dimensionality reduction techniques are often employed to streamline HS image data processing. This paper presents a HS image dataset encompassing left- and right-hand images captured from 100 subjects with varying skin tones. The dataset was annotated using anatomical data to represent vein and non-vein areas within the images. This dataset is utilised to explore the effectiveness of dimensionality reduction techniques, namely: Principal Component Analysis (PCA), Folded PCA (FPCA), and Ward's Linkage Strategy using Mutual Information (WaLuMI) for vein detection. To generate experimental results, the HS image dataset was divided into train and test datasets. Optimum performing parameters for each of the dimensionality reduction techniques in conjunction with the Support Vector Machine (SVM) binary classification were determined using the Training dataset. The performance of the three dimensionality reduction-based vein detection methods was then assessed and compared using the test image dataset. Results show that the FPCA-based method outperforms the other two methods in terms of accuracy. For visualization purposes, the classification prediction image for each technique is post-processed using morphological operators, and results show the significant potential of HS imaging in vein detection.

Abstract
Significance In recent years, the incidence rate of pulmonary embolism (PE) has increased dramatically. Currently, the correct diagnosis rate of PE in China is relatively low, and the diagnosis error rate and missed diagnosis rate were as high as about 80%. The most standard method of PE detection is pulmonary artery digital subtraction angiography (DSA), but pulmonary artery DSA is an invasive examination, and patients can have certain risks and discomfort. Noninvasive monitoring of PE remains challenging in cardiovascular medicine. Aim We attempt to study the light propagation in human thoracic tissues and explore the possibility of near-infrared spectroscopy (NIRS) in noninvasive detection of PE. Approach In this study, by utilizing the Monte Carlo simulation method for voxelized media and the Visible Chinese Human dataset, we quantified and visualized the photon migration in human thoracic region. The influence of the development (three levels) of PE on the light migration was observed. Results Results showed that around 4.6% light fluence was absorbed by the pulmonary tissue. The maximum signal sensitivity distribution reached 0.073% at the 2.8- to 3.1-cm light source-detector separation. The normalized light intensity was significantly different among different PE levels and formed a linear relationship (r 2 = 0.998 , p < 10 - 5 ). Conclusions The study found that photons could reach the pulmonary artery tissue, the light intensity was linearly related to the degrees of embolism, PE could be quantitatively diagnosed by NIRS. Meanwhile, the optimized distance in between the light source and detector, 2.8 to 3.1 cm, was recommended to be used in future potential noninvasive optical diagnosis of PE.

Abstract
Arm Venous Segmentation plays a crucial role in smart venipuncture. The difficulties faced in locating veins for intravenous procedures can be diminished using computer vision for vein imaging. To facilitate this, a high-resolution dataset consisting of arm images was curated and has been presented in this study. Leveraging the ability of Near Infrared Imaging to easily detect veins, ambient lighting conditions were created inside a small enclosure to capture the images. The acquired images were annotated to create the corresponding masks for the dataset. To extend the scope and assert the usability of the dataset, the images, and corresponding masks were used to train an image segmentation model. In addition to using basic preprocessing and image augmentation based techniques, a U-Net based algorithmic architecture has been used to facilitate the task of segmentation. Subsequently, the results of performing image segmentation after applying the preprocessing methods have been compared using various evaluation metrics and have been visualised in the study. Furthermore, the possible applications of the presented dataset have been investigated in the study.

Abstract
Managing medical procedures for children with problematic disorders is a challenging approach, especially in the case of blood withdrawal for autism spectrum disorder-affected children. Peripheral blood mononuclear cells (PBMC) represent an important cellular model to study immune responses and drug toxicity. The monocytic cells, a fraction of PBMC, are strongly involved in some pathophysiological processes, such as inflammation and immune system changes. Here, we propose a simple, reliable protocol for obtaining peripheral blood-derived mononuclear cells from small volumes of blood samples.

Abstract
Accessing blood vessels by medical professionals has been a challenge in healthcare centers worldwide. The main objective of this work is to investigate the localization of blood vessels in dark skin based on near infrared laser imaging. An 830 nm diode laser was used as a light source to irradiate dark skin mimicking optical phantoms. Phantoms were constructed to simulate dark skin with embedded polymer tubes filled with human blood to mimic subcutaneous veins. Appropriate image processing techniques were also used to enhance the detection and depth resolved differentiation of the vein phantoms. Results show that a linear regression model can represent the relation between the grey level in subcutaneous vein images and the depth of vessels down to 3 mm or deeper (n = 15, R2 = 0.88, P < 0.001). The effect of laser power on the system performance is also discussed. Analysis of the collected images demonstrates the feasibility of 830 nm laser imaging for differentiating vein depths under dark skin surface. The proposed method would enhance the localization of invisible subcutaneous veins. This, in turn, would further improve the success rate of related medical procedures such as blood sampling, drawing, in the dark skin population.

Abstract
Multispectral photography offers a wide range of applications for forensic investigations. It is commonly used to detect latent evidence and to enhance the visibility of findings. Additionally, three-dimensional (3D) full-body documentation has become much easier and more affordable in recent years. However, the benefits of performing 3D imaging beyond the visible (VIS) spectrum are not well known, and the technique has not been widely used in forensic medical investigations. A multicamera setup was used to employ multispectral photogrammetry between 365 and 960 nm in postmortem investigations. The multicamera setup included four modified digital cameras, ultraviolet (UV) and near-infrared (NIR) light sources and supplemental lens filters. Full-body documentation was performed in conjunction with the use of a medical X-ray computed tomography (CT) scanner to automate the imaging procedure. Textured 3D models based on multispectral datasets from four example cases were reconstructed successfully. The level of detail and overall quality of the 3D reconstructions varied depending on the spectral range of the image data. Generally, the NIR datasets showed enhanced visibility of vein patterns and specific injuries, whereas the UV-induced datasets highlighted foreign substances on the skin. Three-dimensional multispectral full-body imaging enables the detection of latent evidence that is invisible to the naked eye and allows visualization, documentation and analysis of evidence beyond the VIS spectrum.

Abstract
Using near-infrared (NIR) light with 700-1200 nm wavelength, transillumination images of small animals and thin parts of a human body such as a hand or foot can be obtained. They are two-dimensional (2D) images of internal absorbing structures in a turbid medium. A three-dimensional (3D) see-through image is obtainable if one can identify the depth of each part of the structure in the 2D image. Nevertheless, the obtained transillumination images are blurred severely because of the strong scattering in the turbid medium. Moreover, ascertaining the structure depth from a 2D transillumination image is difficult. To overcome these shortcomings, we have developed a new technique using deep learning principles. A fully convolutional network (FCN) was trained with 5,000 training pairs of clear and blurred images. Also, a convolutional neural network (CNN) was trained with 42,000 training pairs of blurred images and corresponding depths in a turbid medium. Numerous training images were provided by the convolution with a point spread function derived from diffusion approximation to the radiative transport equation. The validity of the proposed technique was confirmed through simulation. Experiments demonstrated its applicability. This technique can provide a new tool for the NIR imaging of animal bodies and biometric authentication of a human body.

Abstract
BACKGROUND Pediatric nurses should be able to use techniques that increase the success rate or shorten the procedural duration of peripheral intravenous catheterization (PIVC). OBJECTIVES This study was performed to define the effect of the infrared vein visualization device support on the success of PIVC in pediatric patients aged 0 to 3 years. Success was determined based on the number of attempts per patient, the duration of the procedure, the success rate of first attempts, and the pain levels of the children. METHODS The study was a randomized, controlled experimental study on 54 children aged 0 to 3 years. RESULTS Peripheral intravenous catheterization in the study group was performed with fewer attempts (study group: 1.44 ± 0.85 [median, 1]; control group: 2.41 ± 1.99 [median, 2]; P = 0.016) and in a shorter period (study group: 44.37 ± 32.22 [median, 40 seconds]; control group: 168.89 ± 171.54 [median, 112 seconds; P = 0.001), and the first attempt success rate in the study group (74.1%) was higher than in the control group (40.7%; P = 0.028). Also, the pain level of the children in the study group was significantly lower than that in the control group (P < 0.05). CONCLUSIONS In conclusion, PIVC supported by the infrared vein visualization device reduces the number of attempts per patient, reduces the duration of the procedure, and increases the success rate of first attempts, and there is procedural pain; therefore, vein visualization improves the success of PIVC.

Abstract
PURPOSE To change pediatric oncology nursing management of peripheral intravenous catheter (PIVC) insertion and care based on current best evidence. DESIGN AND METHODS Practice change strategies were developed, and nurses completed education on proper PIVC insertion, dressing placement, and ongoing PIVC assessment with emphasis on preventing chemotherapy extravasation. Nurses also completed a chemotherapy course as part of their orientation program. The plan for PIVC practice change was based on evidence from published research and established PIVC care guidelines. Pre-assessment data revealed numerous PIVC attempts and a high incidence of extravasation (42%) in children with cancer receiving treatment in Malawi. RESULTS Post-assessment data nine months later resulted in a reduced extravasation rate from 42% to 4% using point prevalence assessments. PIVC insertion attempts reduced following education and guideline implementation; 81% of children required more than 3 PIVC insertion attempts before the practice change. Only 1% of PIVC insertions required more than 3 attempts after education and practice change implementation. Nurses completed a 32-item written examination before the chemotherapy course; the mean score was 50/100. Upon completion of the chemotherapy course, nurses obtained a mean score of 97/100 on the written examination. CONCLUSIONS Using an organized approach to nursing practice change improved PIVC care in children with cancer. PRACTICE IMPLICATIONS This project provides evidence that nursing practice change strategies can be used in any setting including countries like Malawi with limited resources.

Abstract
BACKGROUND Peripheral intravenous catheterization is one of the most frequently encountered medical procedures for hospitalized children and is one that can often be painful. Pediatric nurses should therefore use techniques that increase the success rate or shorten the duration of peripheral intravenous catheterization. OBJECTIVES This study was performed with the objective of determining the effect of using a vein visualization device on the success of the procedure. Success was determined based on the number of attempts per patient, the duration of the procedure, and the first stick success rate. METHODS This was a randomized, controlled experimental study on 129 children aged 3 to 18 years. RESULTS The duration of peripheral intravenous catheterization was shorter in the study group (S) than in the control (C) patients (37.24 ± 20.07 vs 172.65 ± 153.21 seconds; P = 0.001), with fewer attempts (S, 1.08 ± 0.28; C, 2.23 ± 1.57; P < 0.01). The first stick success rate was higher than [corrected] the control group (S, 91.7%; C, 47.4%; P = 0.001). CONCLUSIONS Peripheral intravenous catheterization using vein visualization device support reduces the number of attempts per patient and the operation duration but increases the rate of first stick success. We may therefore state that vein visualization device support improves the success of peripheral intravenous catheterization.

Abstract
PURPOSE In this paper, we present a vein imaging system to combine reflectance mode visible spectrum images (VIS) with transmission mode near-infrared (NIR) images in real time. Clear vessel localization is achieved in this manner with combined NIR-VIS dual-modal imaging. METHODS Transmission and reflectance mode optical instrumentation is used to combine VIS and NIR images. Two methods of displaying the combined images are demonstrated here. We have conducted experiments to determine the system's resolution, alignment accuracy, and depth penetration. Vein counts were taken from the hands of test subjects using the system and compared with vein counts taken by visual analysis. RESULTS Results indicate that the system can improve vein detection in the human hand while detecting veins of a diameter < 0.5 mm at any working distance and of a 0.25 mm diameter at an optimal working distance of about 30 cm. The system has also been demonstrated to clearly detect silicone vessels with artificial blood of diameter 2, 1, and 0.5 mm diameter under a tissue depth of 3 mm. In a study involving 25 human subjects, we have demonstrated that vein visibility was significantly increased using our system. CONCLUSIONS The results indicate that the device is a high-resolution solution to near-surface venous imaging. This technology can be applied for IV placement, morphological analysis for disease state detection, and biometric analysis.

Abstract
Intravenous (IV) procedures are often difficult due to the poor visualization of subcutaneous veins. Because existing vein locators lack the ability to assess depth, and also because mis-punctures and poor vascular access remain problematic, we propose an imaging system that employs diffuse reflectance images at three isosbestic wavelengths to measure both the depth and thickness of subcutaneous veins. This paper describes the proposed system as well as proof-of-principle experimental demonstrations. We initially introduce the working principle and structure of the system. All measurements were based on the Monte Carlo (MC) method and accomplished by referring an optical density (OD) ratio to a multi-layer diffuse reflectance model. Results were all validated by comparative ultrasound measurements. Experimental trials included 11 volunteers who were subjected to both ultrasound measurements and the proposed optical process to validate the system's applicability. However, the unreliability of the "thickness" measurement of the vein may be due to the fact that the veins have collapsible walls - so excess pressure by the transducer will give a false thickness.

Abstract
Approximately 90% of hospitalized patients have a short peripheral intravenous catheter (SPC) placed. Methods of inserting the catheter have evolved over time and now include the use of ultrasound (US)-guided procedures for placement. Little is known about the impact that US-guided procedures have on the vein. This study compared the rate of venous thrombosis in patients with and without US-guided catheter placement. This prospective, single-blind, observational study assessed for venous thrombosis in 153 veins from 135 patients. Veins were evaluated by a research nurse blinded to the method of placement between 48 and 72 hours after the SPC was placed. The Fisher exact test showed a significant difference between vessel compressibility and catheter insertion method (P = .0012). The proportion of noncompressible veins was significantly greater when US was used in comparison with freehand SPC insertion. The Mantel-Haenszel chi-square value of 10.34 (P = .0013) showed that US insertion technique is associated with a higher likelihood of noncompressible veins. This pilot study provides compelling evidence that the use of US to assist with catheter placement is associated with a higher rate of noncompressible veins at day 2 or 3. Further studies are needed with a larger sample to determine the generalizability of the results from this pilot study.

Abstract
[abstFig src='/00290002/08.jpg' width='300' text='The VAID helps to select proper IV insertion sites' ] Peripheral intravenous (IV) line placement is one of the most invasive and painful procedures performed by nurses. Although it is a common nursing procedure, sufficient and effective skill training is necessary before nurses, especially new nurses, work with patients. Vascular access imaging devices (VAIDs) have been developed and put into use in hospitals. Many studies have been conducted to evaluate the effectiveness of the device in clinical settings such as in neonatal care, pediatric care, emergency care, etc., but the effectiveness of the device in training nurses who have just recently graduated has rarely been reported, especially in Japan. In this paper, we report on a quasi-experimental study that evaluated the effectiveness of the VAID for training recent nursing school graduates to successfully perform IV line placement. Eleven newly registered nurses participated in this study. Their preparations were video recorded for analysis. Students’<span class=”bold”>t</span>-tests were used to compare time and success rates of IV placement with VAID assistance and without it. Furthermore, subjects reported their feelings and the self-evaluation related to VAID use by answering a questionnaire, and their responses were analyzed. The results showed no significant change in the length of time needed nor in the success of peripheral IV line placement when the VAID was used; however, nurses indicated the VAID did help them in deciding where the IV should be inserted. These results suggest that the use of the VAID could be clinically meaningful as an IV training tool and that it could reduce the time needed to select venipuncture sites.

Abstract
This paper proposes a multisensory system for the detection and localization of peripheral subcutaneous veins, as a first step for achieving automatic robotic insertion of catheters in the near future. The multisensory system is based on the combination of a SWIR (Short-Wave Infrared) camera, a TOF (Time-Of-Flight) camera and a NIR (Near Infrared) lighting source. The associated algorithm consists of two main parts: one devoted to the features extraction from the SWIR image, and another envisaged for the registration of the range data provided by the TOF camera, with the SWIR image and the results of the peripheral veins detection. In this way, the detected subcutaneous veins are mapped onto the 3D reconstructed surface, providing a full representation of the region of interest for the automatic catheter insertion. Several experimental tests were carried out in order to evaluate the capabilities of the presented approach. Preliminary results demonstrate the feasibility of the proposed design and highlight the potential benefits of the solution.

Abstract
Introduction: Biomedical devices are tools used for locating invisible and impalpable peripheral veins. The purpose of this article is to give a systematic review and analysis of existing studies on the available biomedical devices used for locating peripheral veins and on their effectiveness in clinical practice. Methods: Databases CINAHL, Medline and ScienceDirect were used for the literature review and analysis. The search was performed with the following key words in English: devices, visualization, technology, cannulation, vein, nursing care, with Boolean operators 'AND' and 'OR'. The analysis included randomized and experimental clinical studies published in the English language in the period from 2000 to August 2016. From a total of 1,020 retrieved studies, 17 were included in the detailed analysis. Results: The results of the analysis have shown that the success rate of the first attempt of intravenous cannulation using biomedical devices in more than half of the studies was not significantly higher than when the process was performed using the conventional method. The success of the first attempt of intravenous cannulation mostly depends on the experience and skills of nurses. Biomedical devices are more helpful for novice nurses who do not perform cannulation on a daily basis, for beginners and nursing students. Discussion and conclusions: Based on research, we cannot affirm that biomedical devices significantly contribute to easier peripheral venous cannulation. Further research is required to validate the advantages of such an approach. However, this is limited due to the affordability issues of such biomedical devices.

Abstract
Venipuncture is an important health diagnosis process. Although venipuncture is one of the most commonly performed procedures in medical environments, locating the veins of infants, obese, anemic, or colored patients is still an arduous task even for skilled practitioners. To solve this problem, several devices using infrared light have recently become commercially available. However, such devices for venipuncture share a common drawback, especially when visualizing deep veins or veins of a thick part of the body like the cubital fossa. This paper proposes a new vein-visualizing device applying a new penetration method using near-infrared (NIR) light. The light module is attached directly on to the declared area of the skin. Then, NIR beam is rayed from two sides of the light module to the vein with a specific angle. This gives a penetration effect. In addition, through an image processing procedure, the vein structure is enhanced to show it more accurately. Through a phantom study, the most effective penetration angle of the NIR module is decided. Additionally, the feasibility of the device is verified through experiments in vivo. The prototype allows us to visualize the vein patterns of thicker body parts, such as arms.

Abstract
UNLABELLED We investigated the utility of near-infrared (NIR) light devices for peripheral intravenous cannulation (PIVC) in pediatric patients. We searched three databases, MEDLINE, EMBASE, and the Cochrane CENTRAL. Randomized controlled trials that compared PIVC using NIR light devices and the "traditional" method (with no assistive device) were included. The primary outcome was a failure rate at the first attempt, and the effect size was measured by the risk ratio for failure. Subgroup analysis was performed according to control group risk for failure at first attempt as an indicator of difficult procedure (low vs. high). Eleven studies were included in the meta-analysis. There was no significant difference in the primary outcome between the two methods (risk ratio 1.03, confidence interval 0.89-1.20, I 2 = 48 %). In a subgroup analysis, the subgroup difference between subsets of low and high control group risk was significant (I 2 = 83 %). In the subset of the high control group risk, using NIR light devices showed a lower risk for failure than the traditional method (risk ratio 0.81, confidence interval 0.64-1.01, I 2 = 0 %). CONCLUSION Using NIR light devices did not have an impact on overall failure rate at the first attempt at PIVC in pediatric patients. What is Known: • Near-infrared light devices have been used to help vascular access especially for the pediatric patients. But, their utilities reported in previous studies were conflicting. What is New: • From this study, we could not find out overall benefit of using near-infrared light devices for pediatric peripheral intravenous cannulation. But, this device might be useful for the patients in a difficult condition of successful cannulation.

Abstract
Intravenous cannulation is the process of inserting a cannula into a vein to administrate medication, fluids, or to take blood samples. The process of identification and of locating veins plays an important role during the intravenous cannulation procedure to reduce health care costs and the suffering of patients. This paper compares the three technologies used to assess their suitability and capability for the detection of veins to support the cannulation process. Three types of cameras are used in this study; a visual, an infrared, and a near infrared. The collected images, 103 in total, from the three technologies have been analyzed using a wide range of image processing techniques and compared with identification templates to evaluate the performance of each technology. The results show that the near infrared technology supported by suitable LED illumination is the most effective for the visualization of veins. However, infrared thermography is found to be successful when followed by a cold stimulation.

Abstract
A novel 3D reconstruction and fast imaging system for subcutaneous veins by augmented reality is presented. The study was performed to reduce the failure rate and time required in intravenous injection by providing augmented vein structures that back-project superimposed veins on the skin surface of the hand. Images of the subcutaneous vein are captured by two industrial cameras with extra reflective near-infrared lights. The veins are then segmented by a multiple-feature clustering method. Vein structures captured by the two cameras are matched and reconstructed based on the epipolar constraint and homographic property. The skin surface is reconstructed by active structured light with spatial encoding values and fusion displayed with the reconstructed vein. The vein and skin surface are both reconstructed in the 3D space. Results show that the structures can be precisely back-projected to the back of the hand for further augmented display and visualization. The overall system performance is evaluated in terms of vein segmentation, accuracy of vein matching, feature points distance error, duration times, accuracy of skin reconstruction, and augmented display. All experiments are validated with sets of real vein data. The imaging and augmented system produces good imaging and augmented reality results with high speed.

Abstract
OBJECTIVE To compare the performance on the detection of the invisible veins between our modified prototype device and an existing device in elderly hospitalized patients. METHODS A prospective, cross-sectional, and observational study was performed in the invisible veins in elderly patients. The major variables, skin color near the invisible veins, and diameter and depth of the invisible veins were measured. The vein visualization rate was calculated as the ratio of the visualized veins to the invisible veins by the visualization device. RESULTS We analyzed 53 invisible veins in the cubital fossa and 56 invisible veins in the forearm in a total of 72 patients (median age, 73 years). The visualization rate for our prototype device was higher than that for an existing device in the cubital fossa and the forearm sites. The visualized veins of the prototype device had a higher intensity ratio than that of an existing device. No significant differences were observed in the body mass index, vein depth, and vein diameter of the visualized veins at the cubital fossa and forearm sites. CONCLUSION The prototype surpassed the existing device in visualizing the invisible veins. However, the prototype was unable to visualize all the invisible veins. We need to look for ways to reduce noise and to visualize the invisible veins, and the visualization rate of devices needs to be investigated in further association with the percentage of success with actual intravenous access and locating time to vein.

Abstract
BACKGROUND Recently, various near-infrared vascular imaging devices aimed at facilitating peripheral intravenous cannulation (PIC) were introduced, all claiming to increase success rate of PIC. We evaluated the clinical utility of a near-infrared vascular imaging device (VascuLuminator(®)) in pediatric patients who were referred to the anesthesiologist because of difficult cannulation. METHODS There were 226 consecutive children referred to pediatric anesthesiologists by the treating pediatrician of the in- and outpatient clinic, because of difficulties with intravenous cannulation, were included in this cluster randomized clinical trial. The presence and use of the near-infrared vascular imaging device for PIC was randomized in clusters of 1 week. Success at first attempt (Fisher exact test) and time to successful cannulation (Log-rank test) were assessed to evaluate differences between groups. RESULTS Success at first attempt in the group with the VascuLuminator(®) (59%) was not significantly different from the control group (54%, P = 0.41), neither was the median time to successful cannulation: 246 s and 300 s, respectively (P = 0.54). CONCLUSIONS Visualization of blood vessels with near-infrared light and with near-infrared vascular imaging device did not improve success of PIC in pediatric patients who are known difficult to cannulate.

Abstract
Excessive venipunctures are both time- and resource-consuming events, which cause anxiety, pain, and distress in patients, or can lead to severe harmful injuries. We propose a low-cost mobile health solution for subcutaneous vein detection using near-infrared spectroscopy, along with an assessment of the current state of the art in this field. The first objective of this study was to get a deeper overview of the research topic, through the initial team discussions and a detailed literature review (using both academic and grey literature). The second objective, that is, identifying the commercial systems employing near-infrared spectroscopy, was conducted using the PubMed database. The goal of the third objective was to identify and evaluate (using the IEEE Xplore database) the research efforts in the field of low-cost near-infrared imaging in general, as a basis for the conceptual model of the upcoming prototype. Although the reviewed commercial devices have demonstrated usefulness and value for peripheral veins visualization, other evaluated clinical outcomes are less conclusive. Previous studies regarding low-cost near-infrared systems demonstrated the general feasibility of developing cost-effective vein detection systems; however, their limitations are restricting their applicability to clinical practice. Finally, based on the current findings, we outline the future research direction.

Abstract
Intravenous cannulation can be difficult in children. Recently, new devices using near-infrared light to make blood vessels visible have become available. We aimed to evaluate the effectiveness of three such devices in facilitating peripheral intravenous cannulation in children. In this cluster randomised clinical trial, daily operating rooms at a tertiary childrens' hospital were randomised to the use of the VeinViewer®, AccuVein® AV300, VascuLuminator Vision® or to a control group. We included 1913 children between birth and 18 years scheduled for elective surgery. Suitable veins for cannulation were more easily visible with the VeinViewer (307/322 (95.3%)) and AccuVein (239/254 (94.1%)) devices than with VascuLuminator (229/257 (89.1%)) (p = 0.03). However, success at the first attempt was not significantly different among groups, ranging from 73.1% to 75.3% (p = 0.93). We conclude that although vein visibility is enhanced, near-infrared devices do not improve cannulation.
