Abstract
INTRODUCTION The insertion of a peripheral venous line is of paramount importance in the stabilisation of critically ill patients. It is a preferred method of venous access over more invasive techniques due to its immediacy and fewer complications. Difficulties of catheterisation can result in delays to treatment, increased complication risks and pain, and a waste of valuable time and healthcare resources. Our hypothesis is that infrared vein illumination could improve the success rate of peripheral venous catheterisation in critically ill patients at risk of difficult catheterisation. METHODS AND ANALYSIS This is a prospective, multicentre, randomised, open-label controlled trial. It will be conducted in France and will involve critically ill patients at risk of difficult peripheral catheterisation. Patients will be randomly assigned to usual care or infrared vein illumination. The primary outcome is the rate of successful peripheral venous catheterisation at first puncture. Secondary outcomes include time to placement, overall rate of successful peripheral venous catheterisation, number of punctures, quality (calibre of the catheter), replacement rate, need for central line and local complications (dysfunction, diffusion, haematoma and lymphangitis). ETHICS AND DISSEMINATION The study has been granted ethical approval (CPP Ile de France 1). Following the provision of informed consent, patients will be included in the study. The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03932214.

Abstract
Venipuncture for blood collection is frequently delegated to medical or nursing students, while their individual skills depend on the quality of teaching. The aim of this study was to evaluate the use of a near infrared imaging (NIR) system on the visualization of veins and its potential benefit for the education of medical personnel. Participants answered a questionnaire following standardized venipuncture for blood sampling with the help of an NIR device. Vein visibility with the NIR device and its ability to facilitate venipuncture were examined. Visibility of veins was significantly better with the NIR, and its direction was clearly delineated. Sixty-nine percent of the participants stated that they felt more secure with venipuncture after using the NIR device. Patients' individual factors limited the visibility of veins. The adjuvant use of an NIR system for venipuncture improves participants' subjective skills through visualization of veins and their direction.

Abstract
Extravasation, the unintended leakage of intravenously administered substances, poses significant challenges in cancer treatment, particularly during chemotherapy and radiotherapy. This comprehensive review explores the pathophysiology, incidence, risk factors, clinical presentation, diagnosis, prevention strategies, management approaches, complications, and long-term effects of extravasation in cancer patients. It also outlines future directions and research opportunities, including identifying gaps in the current knowledge and proposing areas for further investigation in extravasation prevention and management. Emerging technologies and therapies with the potential to improve extravasation prevention and management in both chemotherapy and radiotherapy are highlighted. Such innovations include advanced vein visualization technologies, smart catheters, targeted drug delivery systems, novel topical treatments, and artificial intelligence-based image analysis. By addressing these aspects, this review not only provides healthcare professionals with insights to enhance patient safety and optimize clinical practice but also underscores the importance of ongoing research and innovation in improving outcomes for cancer patients experiencing extravasation events.

Abstract
Peripheral venous catheter placement (PVCP) is difficult for children due to the small diameter of their veins in adipose tissue. The transilluminator device (TD) is proposed as the effective method for PVCP. Therefore, this meta-analysis aimed to assess the effect of TD on first attempt success rate (FASR), mean the number of attempts (MNA), and mean duration of successful PVC placement (MDSPP) in children. In a systematic review and meta-analysis, an extensive search of online databases including PubMed, Scopus, Science Direct, Web of sciences, Cochrane, Clinical trial.gov, ProQuest, and Google scholar search engine was conducted. Keywords were combined and searched from the earliest records up to December 2021. The current meta-analysis was performed using STATA V.14.0 software. Six studies (four RCTs and two non-RCTs design) were included in the present meta-analysis. Analysis showed using of TD significantly led to FASR to 34% in studies with RCTs design (RR = 1.34; CI = 1.18-1.53) although, non-RCT studies did not indicate it (RR: 0.95; CI = 0.50-1.79). Also, one RCT (WMD = -0.24; CI = -0.4 -0.08) and two non-RCTs 0.05 (WMD = -0.05; 95% CI = -0.46-0.37) reported the MNA. Two RCTs (WMD: -24.30; CI = -53.50-4.89) and one non-RCT (WMD: -295.20; CI = -359.34 to -231.06) found TD decreased MDSSP. RCTs and non-RCTs studies showed different results in terms of some outcomes. Based on the results of four RCTs studies, the use of TD significantly increased the FASR of PVCP. The results of two non-RCTs also showed TD insignificantly decreased the FASR of PVCP. More evidence (RCT design) is required for decision-making about the effectiveness of TD on successful PVCP.

Abstract
Recent studies in transillumination imaging for developing an optical computed tomography device for small animal and human body parts have used deep learning networks to suppress the scattering effect, estimate depth information of light-absorbing structures, and reconstruct three-dimensional images of de-blurred structures. However, they still have limitations, such as knowing the information of the structure in advance, only processing simple structures, limited effectiveness for structures with a depth of about 15 mm, and the need to use separated deep learning networks for de-blurring and estimating information. Furthermore, the current technique cannot handle multiple structures distributed at different depths next to each other in the same image. To overcome the mentioned limitations in transillumination imaging, this study proposed a pixel-by-pixel scanning technique in combination with deep learning networks (Attention Res-UNet for scattering suppression and DenseNet-169 for depth estimation) to estimate the existence of each pixel and the relative structural depth information. The efficacy of the proposed method was evaluated through experiments that involved a complex model within a tissue-equivalent phantom and a mouse, achieving a reconstruction error of 2.18% compared to the dimensions of the ground truth when using the fully convolutional network. Furthermore, we could use the depth matrix obtained from the convolutional neural network (DenseNet-169) to reconstruct the absorbing structures using a binary thresholding method, which produced a reconstruction error of 6.82%. Therefore, only one convolutional neural network (DenseNet-169) must be used for depth estimation and explicit image reconstruction. Therefore, it reduces time and computational resources. With depth information at each pixel, reconstruction of 3D image of the de-blurred structures could be performed even from a single blurred image. These results confirm the feasibility and robustness of the proposed pixel-by-pixel scanning technique to restore the internal structure of the body, including intricate networks such as blood vessels or abnormal tissues.

Abstract
Biometric recognition techniques have become more developed recently, especially in security and attendance systems. Biometrics are features attached to the human body that are considered safer and more reliable since they are difficult to imitate or lose. One of the popular biometrics considered in research is palm veins. They are an intrinsic biometric located under the human skin, so they have several advantages when developing verification systems. However, palm vein images obtained based on infrared spectra have several disadvantages, such as nonuniform illumination and low contrast. This study, based on a convolutional neural network (CNN), was conducted on five public datasets from CASIA, Vera, Tongji, PolyU, and PUT, with three parameters: accuracy, AUC, and EER. Our proposed VeinCNN recognition method, called verification scheme with VeinCNN, uses hybrid feature extraction from a discrete wavelet transform (DWT) and histogram of oriented gradient (HOG). It shows promising results in terms of accuracy, AUC, and EER values, especially in the total parameter values. The best result was obtained for the CASIA dataset with 99.85% accuracy, 99.80% AUC, and 0.0083 EER.

Superficial vessel-based near infrared-assisted patient position recognition and real-time monitoring system (VIPS) for radiotherapy: A proof-of-concept study. Med Phys 2023; 50:7967-7979.

Abstract
BACKGROUND The accuracy and precision of patient position in radiotherapy process have dramatic impacts on the tumor local control and therapy-related side effects, and there exist demands to explore effective positioning solutions, particularly in the era with great progress in imaging recognition and matching. PURPOSE Superficial vessel-based near infrared-assisted patient position recognition and real-time monitoring system (VIPS) was proposed to develop an automated, operator-independent and skin marker-free imaging system to improve patient setup and intrafractional motion monitoring. METHODS VIPS includes two components, the imaging module and the image alignment software. Using a simulated blood vessel model, multiple NIR sources with various wavelength and bolus (pseudo-skin) were evaluated in terms of imaging quality to determine the optimal light source and the upper limit of superficial fatty tissue thickness. Then the performance of VIPS with reference to either CBCT or laser setup system was conducted using 3D phantom and clinical cases enrolled into the registered clinical trial. The position displacement from VIPS and laser system was compared, as well as the systematic and random errors of VIPS setup procedure. RESULTS The NIR light source with the combined wavelengths of 760 nm + 940 nm (S760+940 nm ) provided the best performance among multiple tested light sources. The bolus (superficial fatty layer) thickness over 5 mm could dramatically compromise the NIR detection of vessels beneath. In the phantom study, the translational positional displacements according to VIPS guidance were within the submillimeter level with reference to CBCT, indicative of high setup accuracy. The clinical trial showed the prototype VIPS could effectively detect and control position displacement of patients in translational and rotational directions within an acceptable range, which was non-inferior to conventional laser/skin marker system. CONCLUSION This proof-of-concept study validated the feasibility and reliability of VIPS in guiding radiotherapy setup. However, limitations and technical challenges should be resolved prior to further clinical evaluation, including isocenter alignment, potential NIR image distortion and the impact of the superficial tissues on the recognition of vessels.

[PMID: 37960594 PMCID: PMC10650145 DOI: 10.3390/s23218895] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 10/25/2023] [Accepted: 10/26/2023] [Indexed: 11/15/2023]
Abstract
Blood vessel visualization technology allows nursing staff to transition from traditional palpation or touch to locate the subcutaneous blood vessels to visualized localization by providing a clear visual aid for performing various medical procedures accurately and efficiently involving blood vessels; this can further improve the first-attempt puncture success rate for nursing staff and reduce the pain of patients. We propose a novel technique for hyperspectral visualization of blood vessels in human skin. An experiment with six participants with different skin types, race, and nationality backgrounds is described. A mere separation of spectral layers for different skin types is shown to be insufficient. The use of three-wavelength indices in imaging has shown a significant improvement in the quality of results compared to using only two-wavelength indices. This improvement can be attributed to an increase in the contrast ratio, which can be as high as 25%. We propose and implement a technique for finding new index formulae based on an exhaustive search and a binary blood-vessel image obtained through an expert assessment. As a result of the search, a novel index formula was deduced, allowing high-contrast blood vessel images to be generated for any skin type.

Abstract
This work presented the design and fabrication of a blood vessel and breast tumor detection device (BKA-06) based on optical energy spectroscopy. The BKA-06 device uses red-to-near-infrared light-emitting diodes that allow physicians or physicians to visualize blood vessels and surface structures such as breast tumors with the naked eye. The device consists of a built-in current control circuit to have the appropriate brightness (maximum illuminance of 98,592 lux) for the examination of superficial tumors deep under the skin, with a scan time of 3-5 min. The device BKA-06 can facilely observe each layer of blood vessels at the depth of the skin. For breast tumors, the location, size, and invasive areas around the tumor can also be visualized with the naked eye using the BKA-06 sensor. The results show that the BKA-06 sensor can provide clear breast tumor and vascular images, with a penetration of up to 15 cm in the skin and tissue layers of the breast. The breast tumor scanning tests with the BKA-06 sensor gave patients quick results and compared them through cell biopsy and MRI, respectively. The device has the advantages of being simple and easy to use, providing potential practical applications in the medical field and reducing costs for patients when taking MRI or CT scans. Therefore, the BKA-06 device is expected to help doctors and medical staff overcome difficulties in infusion, as well as identify breast tumors to support early breast cancer diagnosis and treatment.

Abstract
Placement of peripheral intravenous catheters (PIVCs) is a frequent occurrence. Yet, PIVCs consistently require multiple attempts for successful cannulation, leading to an increased use of resources and risk of complications. Even though hospitals have established vascular access teams to improve outcomes and increase longevity of PIVCs, not every facility has one, and some struggle to meet demand. In these cases, PIVC placement depends on the confidence and skills of bedside nurses. Difficult access risk identification tools, as well as vein visualization technologies, like near infrared (nIR), have been developed to assist nurses with cannulation. This study sought to explore how hospitals are using vein visualization technology in nurse-driven protocols and to evaluate whether the technology is being meaningfully integrated into venous assessment and PIVC access protocols. In a survey sent to facilities utilizing nIR technology, 48% of respondents incorporated nIR in nurse-driven protocols. Of these respondents, 88% reported improvement in patient satisfaction, 92% saw a reduction in escalations, and 79% reported a reduction in hospital-acquired infections associated with PIVC placement. Integrating vein visualization technology into nurse-driven PIVC placement protocols has the potential to make a positive impact but requires future research to reproduce these findings in clinical studies.

Factors Affecting Peripheral Intravenous Catheter Placement During Pediatric Trauma Resuscitation. J Surg Res 2023; 283:241-248. [PMID: 36423472 PMCID: PMC9990681 DOI: 10.1016/j.jss.2022.10.048] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 09/16/2022] [Accepted: 10/18/2022] [Indexed: 11/22/2022]
Abstract
INTRODUCTION Intravenous access is required for resuscitation of injured patients but may be delayed in children because of challenges associated with peripheral intravenous (PIV) catheter placement. Early identification of factors predisposing patients to difficult PIV placement can assist in deciding strategies for timely intravenous access. METHODS We conducted a retrospective, video-based review of injured children and adolescents treated between April 2018 and May 2019. Patient demographic, physiological, injury, and resuscitation characteristics were obtained from the patient record, including age, race, weight, injury type, Injury Severity Score, initial systolic blood pressure, initial Glasgow Coma Score, intubation status, activation level, and presence of prearrival notification. Video review was used to determine the time to PIV placement, the number of attempts required, the purpose for additional access, and the reason for abandonment of PIV placement. Multivariable regressions were used to determine factors associated with successful placement. RESULTS During the study period, 154 consented patients underwent attempts at PIV placement in the trauma bay. Placement was successful in 139 (90.3%) patients. Older patients (OR [odds ratio]: 0.9, 95% confidence interval [CI]: 0.9, 0.9) and patients who required the highest level activation response (OR: 0.0, 95% CI: 0.0, 0.3) were less likely to have an attempt at PIV placement abandoned. Children with nonblunt injuries (OR: 11.6, 95% CI: 1.3, 119.2) and pre-existing access (OR: 39.6, 95% CI: 7.0, 350.6) were more likely to have an attempt at PIV placement abandoned. Among patients with successful PIV placement, the time required for establishing PIV access was faster as age increased (-0.5 s, 95% CI: -1.1, -0.0). CONCLUSIONS Younger age was associated with abandonment of PIV attempts and, when successful, increased time to placement. Strategies to improve successful PIV placement and alternate routes of access should be considered early to prevent treatment delays in younger children.

Abstract
Since several innovations have recently changed the criteria of choice and management of peripheral venous access (new devices, new techniques of insertion, new recommendations for maintenance), the WoCoVA Foundation (WoCoVA = World Conference on Vascular Access) has developed an international Consensus with the following objectives: to propose a clear and useful classification of the currently available peripheral venous access devices; to clarify the proper indication of central versus peripheral venous access; discuss the indications of the different peripheral venous access devices (short peripheral cannulas vs long peripheral cannulas vs midline catheters); to define the proper techniques of insertion and maintenance that should be recommended today. To achieve these purposes, WoCoVA have decided to adopt a European point of view, considering some relevant differences of terminology between North America and Europe in this area of venous access and the need for a common basis of understanding among the experts recruited for this project. The ERPIUP Consensus (ERPIUP = European Recommendations for Proper Indication and Use of Peripheral venous access) was designed to offer systematic recommendations for clinical practice, covering every aspect of management of peripheral venous access devices in the adult patient: indication, insertion, maintenance, prevention and treatment of complications, removal. Also, our purpose was to improve the standardization of the terminology, bringing clarity of definition, and classification.

Abstract
OBJECTIVE The literature describes many techniques to increase vein visibility and palpability that facilitate peripheral intravenous catheter insertion. However, there is only one study examining the effect of topical essential black pepper oil on veins. We aimed to determine the effects of topical application of black pepper essential oil on peripheral intravenous catheter insertion success. METHODS This randomized controlled trial was carried out on 60 patients randomly assigned to either the experimental group (n=30) or the control group (n=30) reporting to the endoscopy unit of the clinic between May 2019 and October 2019. The study results were evaluated using an information form, a catheter insertion form, and a visual analog scale (VAS). In the experimental group, black pepper essential oil was used to increase vein degree before the procedure, while in the control group, no extra interventions were applied. The time taken in determining an appropriate vein, time taken for successful catheter insertion, and the patient's and nurse's satisfaction after the process were recorded. RESULTS Significant improvements in vein degree were detected after the experimental group's oil application (p1<0.001). The period of appropriate vein selection and successful catheter insertion showed a statistically significant decrease in the experimental group (p<0.05). The satisfaction levels of patients and nurses in the control group were significantly lower than those of the patients from the experimental group (p<0.05). CONCLUSION Topical black pepper oil application can increase the vein degree and the success of the procedure.

Abstract
The widespread prevalence of obesity continues to rise. Obesity and dental disease share common risk factors and so the demand for dental care for obese patients is escalating. For some of these patients, there is a corresponding need to be able to provide intravenous sedation safely when it is necessary and appropriate to do so. However, obesity often presents with multiple comorbidities and airway complexities, leading to more challenging management and potentially increased risk. The risk assessment process as well as patient monitoring and management strategies will be explored in this article. By reviewing the literature from dentistry and other medical specialties, we also aim to establish the potential benefit in administering supplemental oxygen and the use of capnography in monitoring this cohort of patients.

Abstract
BACKGROUND AND AIM Transilluminator device allow healthcare professionals to visualize peripheral veins without using tourniquet. Aim of the study was to test the ability of three devices (Christie VeinViewer Flex (Christie, Lake Mary, Florida, USA), ICEN IN-G090-2 (ICEN Technology Company Limited, Guangdong, China) and AccuVein AV400 (AccuVein, New York, USA)) to present quality images thought defined criterion. MATERIALS AND METHODS Study was designed as a comparison of technical characteristics, evaluation of image quality and assessment of applicability in different conditions (different viewing angels, conditions of lightning and image visibility under interference of humidity and body lotions) in reference person on two venipuncture sites. RESULTS Devices have different technical characteristics and vary in optimal distance for good quality image (18-30 cm), number of presented veins (1-4), image dimension (6.0-90.3 cm2), length (1.5-8.0 cm) and thickness (2-5 mm) of the dominant blood vessel. Devices present different image visibility under different viewing angels, conditions of lightning and interference of humidity and body lotions (from good quality to unusable images). CONCLUSION Transillumination devices differ in their technical characteristics and performance. The choice of the device should be based on the needs of the particular patient population and the intended use of the device.

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
BACKGROUND As the vein structure gets damaged in patients receiving chemotherapy treatment, placement of peripheral intravenous catheter becomes difficult. To increase the success of peripheral intravenous catheter placement, a vein imaging device and fist clenching can be used. OBJECTIVE The aim of this study was to determine the effect of using a vein imaging device or fist clenching on the determination of an appropriate vein and successful catheter placement time in adult patients receiving chemotherapy. METHODS One hundred thirty-five patients receiving chemotherapy were randomly assigned to either the vascular imaging device group (n = 45), the fist clenching group (n = 45), or the control group (n = 45). In the vascular imaging group, a vascular imaging device was used to determine the appropriate vein; in the fist clenching group, the patients were asked to open and close their palms to determine the appropriate vein; and in the control group, no interventions except for the process steps were applied and the same nurse carried out the catheter insertion. RESULTS The durations of determining the appropriate vein and successful peripheral intravenous catheter insertion were shorter in the device group at a significant level (P < .05) compared with the control group. The satisfaction levels of the patients and the nurse were higher in the device group at a significant level (P < .05) compared with the control group. CONCLUSION The vascular imaging device was effective in determining the proper vein and in successful intravenous catheter insertion time in patients who were receiving chemotherapy. IMPLICATIONS FOR PRACTICE The use of vein imaging device will have positive results for patients and nurses.

Techniques to select site of insertion for a peripheral intravenous catheter with vessel locating devices using light, sounds or tactile actions (or palpations). J Clin Nurs 2021; 30:1091-1098. [PMID: 33440051 DOI: 10.1111/jocn.15654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 12/06/2020] [Accepted: 12/31/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Approximately 80% of patients admitted to acute hospitals have at least one peripheral intravenous catheter inserted during their admission, for the administration of fluids and medicines, and/or diagnostic tests, so the failure rate is concerning. New technology may decrease these rates even when used by inexperienced inserters. The choice of insertion site for an intravenous catheter is a known predictor of catheter failure. Therefore, the objective for this study was to evaluate the utility of vessel locating devices for novice clinicians to select catheter insertion sites in the forearm. METHODS An inter-subject incomplete counterbalanced research design was employed with healthy volunteers. Novice clinicians used either a vessel locating device using light or sound waves or they used palpation to identify relatively superficial veins in the forearm. This was compared to site selection performed by an expert clinician using palpation method only. Measurements of differences were analysed from photos of chosen sites. Bland-Altman agreement analysis was used to plot novice expert agreement. The STROBE checklist was followed in reporting this study (Techniques to select site of insertion for a peripheral intravenous catheter with vessel locating devices (Appendix S1)). RESULTS A total of 32 novice clinicians used three vessel locating devices and a palpation technique. Novice clinicians did not choose more veins for optimum catheter placement when assisted with vessel locating devices compared to palpation techniques. All methods had a similar mean difference between novice and expert measurements and a similar percentage difference in distance from the expert choice. Bland-Altman agreement analysis did not identify any advantage for the novice with vessel locating devices over palpation. CONCLUSION Vessel locating devices do not enhance the ability of novice clinicians any greater than palpation when selecting suitable forearm veins. If vessel locating device approaches are to be adopted in clinical practice to support better insertion outcomes then current PIVC teaching techniques should include structured vessel locating devices theory and practice. RELEVANCE TO CLINICAL PRACTICE Successful insertion of a peripheral intravenous catheter (PIVC) on the first attempt is a challenging procedure for nurses. Careful consideration of the selected site of insertion could modify this risk factor for catheter failure. The choice of PIVC insertion site by a novice clinician compared to an expert does not necessarily improve with the use of vein locating technology. While there is a range of technological devices available to assist with locating vessels, there needs to be more emphasis from educators on how to select an appropriate insertion site for intravenous therapy.

Abstract
AIM The purpose of this research is to estimate the efficiency of vein viewing device on 9-12 year-old children's pain and anxiety. METHODS The research has been designed as an experimental study including pre-and post-test and control groups. Data were collected with personal information form, facial expressions rating scale, state anxiety scale, vein viewing device and a peripheral cannula. Both groups were applied to the state anxiety scale before and after the procedure while the facial expressions rating scale was applied during the procedure. RESULTS Statistically significant difference was found between experimental and control groups regarding processing time, number of transaction attempts and facial expressions rating scale score averages. While there was no difference regarding the state anxiety scales average points of children in experimental and control groups before the procedure, a statistically significant difference was found in an advanced level regarding post-processing state anxiety levels. CONCLUSIONS Usage of vein viewing device during peripheral cannula intervention reduces children's pain and anxiety levels and shortens the durations of the initiative.

Abstract
OBJECTIVE To determine the prevalence of difficult venous access in adult patients admitted to a surgical unit. METHOD This observational prospective cohort study included 235 patients from a Brazilian hospital. Clinical data were collected by direct observation and analyzed by descriptive, inferential statistics, and multiple binomial logistic regressions. Odds ratios were also calculated. RESULTS Most of the patients (66.4%) were men and self-reported as white (59.2%). The prevalence of difficult intravenous access was 32.8%. Predictors of peripheral intravenous cannula insertion failure were history of difficult intravenous access and nonvisibility of the vein. CONCLUSION History of difficult intravenous access and a nonvisible venous network were significant predictors of peripheral cannula insertion failure in adults undergoing clinical surgery. The prevalence of difficult intravenous access was 32.8%.

Abstract
PURPOSE This study was conducted to design services for improving the quality of care of hospitalized children with acute diseases. METHODS The service design process had four phases: discovery, definition, development, and delivery. The participants were 23 mothers of hospitalized children with an acute disease, and seven nurses and three doctors working at a pediatric hospital. Data were collected through self-report questionnaires, in-depth interviews, and observations. The data were analyzed using content analysis and descriptive statistics. RESULTS The participants reported needs for explanations about the treatment, skillful nursing, and environmental improvements. The concept of the services was familiarity and enjoyment, aimed at solving the problems of unfamiliarity and boredom. A six-guideline was presented for improving the quality of care of hospitalized children with acute diseases: improvement of awareness, development of educational materials, improvement of skills, environmental improvements, play activities, and evaluations of user satisfaction. CONCLUSION These findings indicate that nursing services should deliver familiarity and enjoyment to hospitalized children and their families. The findings of this study emphasize that the service design methodology can be used to improve the quality of care of hospitalized children with acute diseases.

Abstract
High recurrence and high costs of treatment are the main problems with venous ulcer management. Therefore, it is of utmost importance to target the exact pathological cause. The role of cutaneous microvalves reflux in the pathogenesis of these ulcers has been confirmed. In this study, 20 chronic venous leg ulcers were prospectively subjected to foam sclerotherapy injection into periulcer veins using direct visualization by AccuVein AV400. Patients having infected ulcers, acute deep vein thrombosis, hypercoagulability, Ankle-Brachial Index <0.9, pregnancy, and/or allergy to the sclerosant were excluded. Endpoints included rates of ulcer size reduction, complete healing, ulcer recurrence, and procedure-related complications. Aethoxysklerol 1% was used in all cases to produce foam employing the double-syringe system. The mean reduction in ulcer surface area, postinjection, was 75% after 8 weeks and 91% after 12 weeks. Nineteen ulcers (95%) healed in a median time of 8 weeks, range 3 to 17 weeks. At 1 year of follow-up, 18 patients (90%) were still ulcer-free, while 1 patient's ulcer (5%) recurred 19 weeks postinjection. No major complications were encountered. Periulcer foam sclerotherapy injection, guided by vein visualization technology, should be one of the main lines of treatment of venous leg ulcers. It offers good results with regard to rapid ulcer healing and low recurrence rate without major risk. Randomized controlled trials are needed to establish these conclusions.

SENSORS (BASEL, SWITZERLAND) 2019; 19:E3573. [PMID: 31426370 PMCID: PMC6719195 DOI: 10.3390/s19163573] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 07/21/2019] [Accepted: 08/13/2019] [Indexed: 12/30/2022]
Abstract
One of the most common means for diagnosis is through medical laboratory testing, which primarily uses venous blood as a sample. This requires an invasive method by cannulation that needs proper vein selection. The use of a vein finder would help the phlebotomist to easily locate the vein, preventing possible pre-analytical error in the specimen collection and even more discomfort and pain to the patient. This paper is a review of the scientific publications on the different developed low-cost vein finder prototypes utilizing camera assisted near infrared (NIR) light technology. Methods: Electronic databases were searched online, these included PubMed (PMC), MEDLINE, Science Direct, ResearchGate, and Institute of Electrical and Electronics Engineers (IEEE) Xplore digital library. Specifically, publications with the terms vein finder prototype, NIR technology, vein detection, and infrared imaging were screened. In addition, reference lists were used to further review related publications. Results: Cannulation challenges medical practitioners because of the different factors that can be reduced by the utilization of a vein finder. A limited number of publications regarding the assessment of personnel performing cannulation were observed. Moreover, variations in methodology, number of patients, type of patients according to their demographics and materials used in the assessment of the developed prototypes were noted. Some studies were limited with regard to the actual human testing of the prototype. Conclusions: The development of a low-cost effective near infrared (NIR) vein finder remains in the phase of improvement. Since, it is being challenged by different human factors, increasing the number of parameters and participants/human for actual testing of the prototypes must also be taken into consideration for possible commercialization. Finally, it was noted that publications regarding the assessment of the performance of phlebotomists using vein finders were limited.

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
The work describes features of the compressed sensing (CS) approach utilized for development of a wearable system for wrist vein recognition with single-pixel detection; we consider this system useful for biometrics authentication purposes. The CS approach implies use of a spatial light modulation (SLM) which, in our case, can be performed differently-with a liquid crystal display or diffusely scattering medium. We show that compressed sensing combined with above-mentioned means of SLM allows us to avoid using an optical system-a limiting factor for wearable devices. The trade-off between the 2 different SLM approaches regarding issues of practical implementation of CS approach for wrist vein recognition purposes is discussed. A possible solution of a misalignment problem-a typical issue for imaging systems based upon 2D arrays of photodiodes-is also proposed. Proposed design of the wearable device for wrist vein recognition is based upon single-pixel detection.

Abstract
Background Avoidance from palatal blood vessel rupture is a major concern during the palatal soft tissue graft surgery. There is no defined chair-side and case-specific palatal blood vessel detection approach to facilitate the harvesting process. The objective of this pilot study is to assess the feasibility of a near-infrared vein visualization system in the screening process of palatal blood vessels. Material and Methods An extraoral vein visualization device (AccuVein AV400) was applied to a total of 304 hemi-maxilla of 152 individuals by two blind examiners. The study groups were classified according to their maximum inter-incisal measurements. The distances between the coronal border of the vessel image and the mid-palatal gingival margins of the adjacent teeth were measured and in each group. The correlations among the measurements were evaluated within groups. Results The blood vessel to the adjacent teeth measurements exhibited no statistical difference between both examiners in all subjects (p<0.001). Correlations between the examiners gradually increased in all groups as the mouth opening rates of the subjects were increased (p<0.001). Conclusions In the current state, screening of the palatal blood vessels via near-infrared vein visualization technology seems to be not suitable for every individual due to the restrictive effect of mouth opening. However, the promising results of this preliminary study demonstrated increasing consistency between the measurements of the examiners as the inter-incisal distance increase which emphasized the need an intraoral version of the device. Considering the lack of local decision-making technology for the detection of palatal blood vessels, further studies are required for development and optimization of these systems. Key words:Near-infrared vein visualization, palatal graft harvesting, surgical complications.

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
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
Vascular access procedures are an important and frequent component of the day-to-day practice of the pediatric surgeon. Most access procedures can be performed percutaneously via Seldinger or modified Seldinger technique and are aided by technology, such as ultrasound and fluoroscopy. Complications, such as infection, do occur, and the pediatric surgeon should be able to diagnose and treat these when they arise. The indications, techniques, and complications of vascular access are covered in this article.

Eur J Pediatr 2016; 175:1975-1988. [PMID: 27785562 DOI: 10.1007/s00431-016-2796-5] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2015] [Revised: 10/09/2016] [Accepted: 10/17/2016] [Indexed: 11/25/2022]
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
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
Over the last four decades, as the rates of obesity have increased, so have the challenges associated with its anesthetic management. In the present review, we discuss perioperative anesthesia management issues that are modifiable by the early involvement of the surgical team. We sum up available evidence or expert opinion on issues like patient positioning, postoperative analgesia, and the effect of continuous positive airway pressure (CPAP) ventilation on surgical anastomosis. We also address established predictors of higher perioperative risk and suggest possible management strategies and concerns of obese patients undergoing same day procedures. Finally, a generalized pharmacological model relevant to altered pharmacokinetics in these patients is presented.

Abstract
Background Excessive venipunctures are a significant problem both in emergency rooms and during hospital stays. Near-infrared (NIR) illumination devices improve venipuncture success rate but their usage is limited by their availability and economic cost. The objectives of this study were to develop a low-cost NIR spectroscopy prototype from a standard mobile device, to evaluate its efficacy and acceptance as an educational tool, and in a clinical setting. Methods Through a user-centric design process a prototype device was developed. Its educational efficacy was evaluated through a non-invasive, observational study (20 student clinicians, 25 subjects) and its acceptance was assessed using quantitative and qualitative analysis. A smaller clinical trial was performed by a group of 4 medical professionals over a period of 6 weeks that involved 64 patients. Results The prototype enables real-time visualization of peripheral veins on a variety of Android-based devices. The prototype was 35.2% more successful in visualizing and locating veins (n = 500 attempts) than the nursing students. The acceptance assessment revealed high perception of usefulness, satisfaction, and ease of use. In the clinical trial, 1.6 (SD 1.3) additional veins per patient were identified compared with the traditional visualization methods. Conclusions To the best of our knowledge this is the first study that describes the design, feasibility and application of an NIR spectroscopy prototype developed on a standard mobile device.

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
Although a serious impediment in haemophilia patients, difficulty accessing peripheral veins has received little attention in clinical studies. New peripheral vein visualization devices could potentially ameliorate difficult venous access (DVA), but their utility remains unproved. The study aim was to survey the frequency, causes and clinical manifestations of DVA and evaluate the clinical utility of a near-infrared (NIR) vein visualizer. In this multicentre prospective study, methods, difficulties and outcomes of venous access were assessed for a single venipuncture in consecutive patients. The impact of an NIR vein visualizer on vein localization, the number of venipuncture attempts and patient stress and pain was determined. Among 450 total patients enrolled, venous access was judged to be difficult in 165 (36.7%), most often because of poor vein condition, young patient age, overweight and difficulty in finding veins. Of the patients with DVA, difficulty in locating veins was encountered in 82.4%, and more than one venipuncture attempt was required in 24.8%. Veins were difficult to locate in significantly fewer DVA patients (P = 0.002) when the NIR vein visualizer was used (76.0%) than not used (92.3%). Pain during venipuncture in DVA patients was also significantly less common (P = 0.019) with use of the NIR vein visualizer (34.0% vs. 55.4%). No effect was observed on venipuncture attempts. DVA affects more than one-third of patients at haemophilia treatment centres. An NIR vein visualizer showed significant promise for facilitating vein location and mitigating patient pain in those patients.

Abstract
OBJECTIVES In the emergency department (ED), intravenous (IV) catheter placement is one of the most frequent interventions and may be a real challenge in some conditions. Improvement of the success rate with new technology represents a great opportunity. This randomized controlled trial aimed to show the superiority of AccuVein to cannulate veins in adults compared to routine care. METHODS After giving written consent, patients were randomized into two groups: routine IV catheter insertion or insertion guided by the AccuVein, which is a hand-held instrument displaying laser light to optimize visualization of veins. The primary outcome was the time to successful placement of catheters. Secondary outcomes included the number of attempts, the rate of failure, technique-related pain, occurrence of movements, and efficiency of IV cannulation as perceived by the operator when using the AccuVein device. Results are given as mean and bootstrapped 95% confidence interval (CI) and percentages. p-values of <0.05 were considered significant. RESULTS A total of 266 six patients were included, with 157 randomized to routine cannulation and 115 to AccuVein. Patient characteristics were similar. Time to successful placement of IV catheter (routine, 98 seconds, 95% CI = 85 to 113 seconds; and AccuVein, 119 seconds, 95% CI = 93 to 154 seconds) was not different between groups (p = 0.24). Secondary outcomes (failure and pain) did not significantly differ, except for movements, which were more frequent when using the AccuVein device (19.1% vs. 10.2%, p = 0.05). Evaluation of the AccuVein by operators was more often negative than positive. CONCLUSIONS Use of the AccuVein did not improve IV cannulation in nonselected ED patients.

Variation of Human Hairiness: A Possible Adaptation to Solar Radiation and Melanin. ANTHROPOLOGICAL REVIEW 2014.

Abstract
Many theories have been advanced to explain human hairlessness, however, there is no consensus. This study of 76 males observed that skin reflectance measuring skin colouration and melanin pigmentation correlated with hair size and follicle density. Individuals with a greater concentration of melanin within the superficial layer of the skin had a lower follicle density and smaller sizes of hairs. In contrast, individuals with a lower melanin concentration and lighter skin colour had a full range of hairiness. This leads to the suggestion that over the course of human evolution, high concentrations of melanin in consistently exposed to ultraviolet radiation areas developed first and that hair loss was a consequence of competition in the skin between melanin production and hair growth. Darker pigmented skin and lower follicle density are significantly correlated (R2=0.283; p<0.05). Individuals with darker skin had a mean of 4.91 follicles per cm2 whereas those with lighter skin reflectance had 11.20 follicles per cm2. This suggests that increased concentrations of melanin in the basal layer of the epidermis may limit hairiness by negatively influencing the skin’s ability to produce hair.

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.
