RESUMO

BACKGROUND: Peripheral intravenous catheterization is frequently performed in emergency units, but it is a procedure which is difficult for healthcare professionals and painful for patients. The primary objective of the present study was to examine the effect on venous dilation, procedure duration and pain severity of local heat, cold and vibration applications performed on the intervention area before peripheral intravenous catheterization in adults. The second objective of the study was to examine the effects of age and gender variables on the participants' pain intensity levels. METHODS: A single-blinded randomized controlled trial. The study included 120 adults who were randomly selected between March and August 2023. One application group (n = 30) received local heat application, one group (n = 30) received local cold application, and one (n = 30) received local vibration using the Buzzy® device. The applications, to the site of the peripheral intravenous catheterization, lasted one minute. The control group (n = 30) received standard peripheral intravenous catheterization application. The groups' vein dilation was assessed with the vein assessment scale, pain felt during catheterization with the visual analog scale, and the duration of the procedure with a chronometer. RESULTS: It was found that the venous dilation of the cold application group was significantly higher (p = 0.010, p = 0.015 respectively) and procedure duration was shorter (p = 0.013, p < 0.001 respectively) than that of the heat and vibration application groups, and its pain severity was significantly lower (p = 0.002, p = 0.001 and p = 0.001 respectively) than that of the control group and the heat and vibration application groups. CONCLUSIONS: It was determined that local cold application for one minute to the area of peripheral intravenous catheterization increased venous dilation, shortened application time, and reduced pain. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT06378424, retrospectively registered 20/04/2024.

RESUMO

BACKGROUND: Virtual reality (VR) distraction can be used during peripheral intravenous catheter (PIC) insertion. The vein imaging devices are recommended for increasing PIC success. OBJECTIVES: This study aimed to evaluate the effect of a Veinlite PEDI2 and passive VR distraction on the first attempt at PIC insertion success, duration of insertion, emotional behavior, pain, fear, and anxiety associated with PIC insertion in children aged 4-10 years in the pediatric emergency department. METHODS: The study was conducted with a total of 160 children who were assigned to groups (control, vein imaging, VR, and vein imaging with VR) through stratified randomization. The duration and number of attempts for PIC insertion were recorded. The children's emotional state, fear, and anxiety were evaluated before and after the procedure. After the procedure, pain was evaluated using the Wong-Baker FACES and Color Analog Scale. The mean scores obtained from the scales were compared using the Kruskal-Wallis test. RESULTS: The PIC success rate on the first attempt was 80-85% in the groups. A significant difference was found between the groups in terms of total emotional behavior scores (KW = 21.608, df = 3, p < 0.001). There were statistically significant differences among the groups in emotional behavior, pain, and anxiety scores after the procedure, while no difference was observed in fear scores (KW = 6.485, df = 3, p = 0.09). CONCLUSIONS: VR distraction effectively reduced pain and anxiety, while the Veinlite PEDI2 did not affect the first attempt at PIC insertion or duration. APPLICATION TO PRACTICE: VR and Veinlite PEDI2 can be used for PIC insertion-related pain and anxiety (ClinicalTrials.gov: NCT06243419).

RESUMO

INTRODUCTION: Distraction methods such as virtual reality and cold vibration device are recommended during intravenous interventions. Few studies have focused on the impact of nonpharmacological interventions on intravenous insertion success. METHODS: A randomized controlled study evaluated effect of virtual reality and cold vibration device application on first-attempt intravenous insertion success and procedure-related pain, fear, and anxiety during intravenous insertion in children. Children aged 4 to 10 years (N = 150) undergoing peripheral intravenous catheterization insertion in the pediatric emergency department were randomized to 1 of 3 groups: virtual reality, cold vibration (Buzzy), and control group. Distraction technique of talking and asking questions of children was used in control group. Primary outcome was first-attempt intravenous insertion success; secondary outcomes were procedure-related pain, fear, and anxiety. Study data were collected using Difficult Intravenous Access score, Emotional Appearance Scale for Children, Wong-Baker Faces Pain Rating Scale, Color Analog Scale, Children's Anxiety Meter-State, and Child Fear Scale. Data were analyzed using chi-square test, Fisher exact test, and Kruskal-Wallis test. RESULTS: There were no significant differences in first-attempt intravenous insertion success rates (virtual reality = 47.2%, Buzzy® = 50%, control = 46.9%), preprocedural emotional appearance scores, and procedure-related pain and anxiety scores. There was no difference between groups for vital signs before, during, and at fifth minute of procedure. DISCUSSION: Virtual reality and Buzzy may decrease procedure-related fear in children during intravenous insertion. This research has shown that pediatric emergency nurses can reduce pain and anxiety by talking to children, and simple distractions such as asking questions are as effective as more technological ones.

RESUMO

INTRODUCTION: Difficulty in accessing peripheral veins in emergency departments increases patients' discomfort and impedes their diagnosis. The objective of this study was to develop and test the prognostic accuracy of an easily applied scale to measure difficult venous access to peripheral veins in emergency departments, called the Adult-Difficult Venous Catheterization scale. METHODS: This prospective observational study was conducted in adults from the hospital catchment area attending the emergency department. Using the Delphi technique, 5 experts reached a consensus regarding a 3-item scale scored from 0 to 5. Concurrent validity and predictive validity were analyzed using a numeric rating scale and the number of access attempts, respectively. Internal consistency and interobserver reliability for 3 independent observers were analyzed using Cronbach alpha and Cohen kappa, respectively. RESULTS: In 392 participants, the concurrent and predictive validity scores pointed to positive relationships with the numeric rating scale (r = 0.82; P < 0.001) and the number of access attempts (r = 0.5; P < 0.001), respectively. The odds ratio for 1 to 2 access attempts versus more than 2 access attempts in relation to the Adult-Difficult Venous Catheterization scale score was 2.76 (95% confidence interval 1.86, 4.08; P < 0.001). Sensitivity and specificity values for the Adult-Difficult Venous Catheterization scale were good, at 93.75% and 78.99%, respectively, as were internal consistency (Cronbach alpha 0.81) and interobserver reliability (Cohen kappa 0.75). DISCUSSION: The Adult-Difficult Venous Catheterization scale is a valid and reliable instrument for predicting difficult venous access in emergency departments.

RESUMO

AIM: The aim of this study was to identify interventions associated with peripheral intravenous catheterization first attempt success in pediatric inpatients and emergency department patients who require vascular access for therapeutic interventions. BACKGROUND: Unsuccessful peripheral intravenous catheterization puts children at risk for increased pain and treatment delays. Effective interventions to increase peripheral intravenous catheterization first attempt success are unclear. DESIGN: Systematic review of randomized controlled trials according to the Cochrane Handbook for the Systematic Review of Interventions. DATA SOURCES: Through November and December 2014, we searched 10 databases including MEDLINE (OVID), EMBASE (OVID) and CINAHL (EBSCO) without date limits. The references of articles were also reviewed. We included full text reports of randomized controlled trials testing intervention first attempt success rates vs. standard of care. REVIEW METHODS: According to inclusion and exclusion criteria set a priori, data were extracted using a standardized tool. We assessed for risk of bias with the Cochrane Collaboration Risk of Bias Tool. Due to unclear reporting narrative synthesis was used to report results. RESULTS: Four cluster randomized control trials and ten randomized control trials involving 4539 participants ranging from 15·6 days to 16 years of age met our inclusion criteria. We excluded the four cluster trials from meta-analysis due to unclear reporting. Interventions did not increase first attempt success rate compared with standard of care. CONCLUSIONS: There was insufficient evidence to support the use of ultrasound, infrared light or transillumination. Interventions to reduce children's pain did not decrease first attempt success. Research examining between-clinician proficiency and persistence differences is absent.

RESUMO

BACKGROUND: Patients in the urology ward often require peripheral intravenous catheters for cancer chemotherapy, antibiotics to treat urinary tract infections, surgery, and other treatments. Moreover, as the elderly population within urology has a high incidence of cancer, many patients also have fragile vasculature. Proper intravenous catheter insertion and management are crucial in such cases. However, no observational studies have revealed specific practices and patient outcomes related to intravenous catheter insertion and management in urology wards. This study aimed to clarify the actual situation of peripheral intravenous catheter placements in patients hospitalized in a general urology ward and investigate the risk factors for patient outcomes such as difficult intravenous access (DIVA) and catheter failure (CF). METHODS: This was a prospective observational study. Medical record data were collected, and the actual catheter placement situation was described. A multivariate logistic regression analysis was performed to investigate the risk factors for DIVA and CF. RESULTS: This study analyzed 180 catheters in 99 patients. The median age of the group was 70 years. The prevalence of DIVA and CF were 9.9% and 35.2%, respectively. A history of intravenous chemotherapy for cancer was positively associated with both DIVA and CF. CONCLUSION: This study's results demonstrate the crucial need for careful insertion and management of intravenous catheters in patients admitted to urology wards. These findings can help identify patients at high risk of DIVA and CF, while hospitalized in the urology ward.

RESUMO

Successful insertion of a peripheral intravenous catheterization requires that veins be sufficiently dilated. This study aimed to clarify the venous dilation effect of including tapping or massaging to the application of a tourniquet at the cutaneous veins of healthy adults' forearms. This was a quasi-experimental study of 30 healthy adult volunteers. Each participant underwent all three venous dilation procedures, which included the tourniquet application (Control condition), the tourniquet application and tapping the participant's forearm (Tapping condition), as well as the tourniquet application combined with massaging the participant's forearm (Massage condition). To clarify the venous dilation effects, venous indices were measured, namely the venous diameter (mm), depth (mm), and palpation score. After applying all venous dilation procedures, the venous diameter and palpation score significantly increased. However, no significant difference was observed between the control condition and each intervention condition. The depth in the control and tapping conditions decreased significantly in contrast to the Massage condition. Moreover, a subgroup (nine participants with a venous diameter less than 3 mm after the control condition) had similar results. This study found that additional tapping or massaging after tourniquet application could be less effective in promoting dilation in the forearm veins of healthy adults. Future studies should examine the efficacy and effectiveness of venous dilation in a wide target population while considering intervention methods.

RESUMO

BACKGROUND: Peripheral intravenous catheterization (PIVC) is pivotal to pediatric medical care; however, it is a challenging technique for pediatricians, and the parameters affecting successful pediatric PIVC establishment have not been fully investigated. METHODS: This prospective observational study collected data from pediatric patients aged less than 18 years who required PIVC. The participants were categorized into five groups for subgroup analysis: newborn, infant, toddler, pre-school, and student (children and adolescent). Data on demography, biochemistry, and PIVC executors were examined to elucidate the most powerful factors affecting the success of PIVC. RESULTS: A total of 935 peripheral venous cannulations conducted within 1 year were studied. Age-subgroup analysis showed the highest failure rate (FR) of PIVC in the infant group (18.4%). No significant difference in BMI standard deviation score was noted among the groups (p-value = 0.430). Compared with those for the success group, more attempts, longer completion time, and more medical staff were needed for the failure group (all p-values < 0.05). A high serum procalcitonin level was correlated with an increased FR (p-value = 0.016). In addition, the success rate was positively associated with the seniority of the operators, except for the 3-year experienced R3 group (93.5%) showing a higher success rate than the 4-year experienced CR group (84.2%). CONCLUSIONS: Difficulty in setting up PIVC was the greatest in infants and even greater than that in newborns. Even though seniority was a cardinal factor in successful PIVC, a high FR was still noted despite the lack of continuous and steady practice.

RESUMO

BACKGROUND: YouTube™ has become a potential way to integrate technology into nursing curriculum and acquire skills. However, it is important to review the accuracy of the information contained in YouTube™. This study was conducted to evaluate the content validity, reliability and quality of YouTube™ videos on peripheral intravenous catheterization. METHODS: In this descriptive study, videos were searched using the keyword 'Peripheral Venous Catheter'. The content validity, reliability and quality of the videos were evaluated using the 'Peripheral Intravenous Catheterization Insertion Skill Form', 'DISCERN Questionnaire', 'Global Quality Scale', respectively. These videos were categorized by their theme, upload source, technical features and analysed statistically. RESULTS: Of the 48 videos, 38 (79.2%) classified as an useful video, 24 (50%) were uploaded by medical educational platforms and 28 (58.3%) had an average technical feature. There was a statistically significant difference between the reliability, quality, content validity scores by the video theme (p < 0.05). The content validity, reliability and quality score of useful videos were higher than misleading videos. In addition, pairwise comparisons indicated that there was a statistically significant difference between the content validity, reliability and quality scores of Peripheral Intravenous Catheterization demonstrated on a person or a mannequin were higher than those applied with ultrasonography (p < 0.05). CONCLUSIONS: As a result of the reviewing of the videos, it was determined that these videos provided useful content. Despite this positive result, some videos provide risky information for patient safety due to issues such as ignoring the asepsis principles and not including proper Peripheral Intravenous Catheterization steps. It may be recommended to consider the Peripheral Intravenous Catheterization steps and patient safety principles in international guidelines in the preparation of videos showing the Peripheral Intravenous Catheterization insertion.

RESUMO

BACKGROUND: Heat application before peripheral intravenous catheterization is recommended for venous dilation. Hot pack application enlarges the venous diameter in healthy adults; however, hot towels (moist and dry heat) are used often in some medical cases. However, it is unclear whether hot towel application promotes venous dilation better than hot pack application. This study compared the venous dilation effect of using a hot towel (moist and dry heat) to a hot pack before applying the tourniquet at an access site for peripheral intravenous catheterization. METHODS: Eighty-eight healthy females aged 18-29 years were recruited for this quasi-experimental study. They underwent three types of heat applications (hot pack, moist hot towel, and dry hot towel [moist hot towel wrapped in a dry plastic bag], all of which were warmed to 40 ± 2 °C and performed for 7 min) to their forearm and tourniquet application for 30 s after each heating. Venous diameter and depth were measured using ultrasonography, and venous palpability and visibility (venous assessment score) was observed as venous dilatation effects. In addition, the skin temperature, stratum corneum hydration, and subjective evaluation of the warmth were measured. RESULTS: There were no significant differences in venous diameter and assessment scores after intervention between the dry hot towel and the hot pack groups, and the effect size was negligible (Cohen's d < 0.20). However, these measurements were significantly lower for the moist hot towel than for the other two heat applications (P < .001). Although there was no significant difference in skin temperature and warmth rating score between the dry hot towel and the hot pack, these were significantly lower for the moist hot towel than for the other two heat applications (P < .001). The amount of change in stratum corneum hydration of the dry hot towel was not significantly different from that of the hot pack; however, that of the moist hot towel was significantly larger than that of the other two heat applications (P < . 001.) CONCLUSIONS: A method in which a towel warmed in hot water is wrapped in a dry barrier may be an alternative to a hot pack. TRIAL REGISTRATION: This study was registered with University Hospital Medical Information Network in Japan (Registration No.: UMIN000048308. Registered on July 7, 2022).

RESUMO

The perioperative cardiac events may be brought about by a relative imbalance of autonomic activities due to excessive psychological and physical stress. The present case study focuses on the asystole that can occur as a serious cardiac adverse event associated with vasovagal reflex likely to be triggered by venipuncture for securing an intravenous line during dental care. In addition, we describe and discuss herein the management of intravenous sedation for a dental phobic patient who experienced the vasovagal reflex involved in an unexpected transient asystole. The patient with vasovagal reflex episodes in daily life, who had no past medical history relevant to cardiovascular disorders, was scheduled for dental extraction under intravenous sedation. Immediately after peripheral intravenous catheterization, she complained of discomfort and nausea, and a II-lead electrocardiogram revealed asystole following bradycardia associated with vasovagal reflex. Oxygenation and intravenous fluid loading in the supine position with elevation of the lower extremities restored sinus rhythm and normal hemodynamics without the intervention of cardiopulmonary resuscitation. With administration of intravenous atropine and betamethasone as premedication, she was uneventfully treated in stress-free psychosomatic conditions under optimal sedation with midazolam without any signs of cardiovascular disorders. After administration of flumazenil, the patient satisfactorily recovered from sedation without re-sedation. The present case suggests that an asystole associated with vasovagal reflex can be triggered by venipuncture for intravenous catheterization during dental anxiety likely to affect the imbalance between sympathetic and parasympathetic activities.

RESUMO

A significant number of adult oncology patients require at least one peripheral intravenous catheter to fulfill their therapeutic plan. Recent evidence indicates that catheter failure rates are high in this cohort, impacting care outcomes and patient experience during cancer treatment. This reality represents a challenge to nurses worldwide since in most international settings they are responsible for delivering quality care during the insertion and maintenance of such devices. This study aims to explore current nursing practices regarding the insertion, maintenance, and surveillance of peripheral intravenous catheters in oncology patients. A two-phase mix-method study was conducted with the nursing team from the surgical ward of a large oncology hospital in Portugal. In phase one (observational prospective study), nurses' practices during catheter insertion and maintenance were observed by the research team and recorded using standardized instruments and validated scales. In phase two, three online focus groups were conducted with the nursing team to present the results observed in phase one and explore their perceptions of current practices. All ethical principles were assured throughout the study. Significant divergent practices were observed and identified by the nurses, especially concerning patient involvement, nurses' adherence to the aseptic, non-touch technique, catheter stabilization and dressing, and catheter flushing and locking. Such practices may partially explain the high complication rate found (26%) and substantiate the need for future intervention in this field.

RESUMO

OBJECTIVES: Peripheral intravenous catheters (PIVC) are the most frequently used invasive devices in medicine. PIVC failure before treatment completion is a significant concern and occurs in 33-69% of patients. Partial dislodgement and accidental removal are some of the reasons for PIVC failure. The most effective dressing and securement method for preventing accidental removal remains unclear. It was the aim of this study to compare the force required to dislodge a PIVC with four commonly used dressing and securement methods. Additionally, costs were calculated. METHODS: Truncated 18-gauge i.v. cannulas were attached onto the forearm of 209 volunteers using four different dressings and securements (sterile absorbent wound dressing covered by two different types of elastic polyester fleece, bordered and non-bordered polyurethane). The force during continuously stronger pulling until dislodgement was recorded. RESULTS: The highest resistance against dislodgement forces could be observed with a sterile absorbent wound dressing covered by two incised elastic polyester fleece dressings. Commercially-manufactured bordered and non-bordered polyurethan film dressings were 20% to 75% more expensive than sterile absorbent wound dressings covered by elastic polyester fleece dressing. CONCLUSIONS: Elastic polyester fleece secured a PIVC against accidental removal by external force best, compared to commercially-manufactured bordered and non-bordered polyurethane film dressing.

RESUMO

BACKGROUND: The design of medical devices impacts upon the performance of healthcare professionals and patient safety. However, multiple devices serving the same function are often available. The purpose of this study was to use simulation as a means of examining the impact of differences in device design on (1) learning of, or attainment of behavioral fluency in, peripheral intravenous cannulation (PIVC); and (2) the generalization, or transfer, of learning on one device to performance of PIVC using an untrained device. METHODS: A total of 25 final cycle medical students participated in this study which used a randomized two-group design. Participants were randomly assigned to learn PIVC using either a closed PIVC device (a single device which consists of an intravenous cannula with a pre-attached extension tube; n = 14) or an open PIVC device (a two-piece device made up of an intravenous cannula and a separate extension tube which is attached following insertion of the cannula; n = 11). Task analyses were developed for the performance of PIVC using each device. Subsequently, simulation-based fluency training was delivered to both groups using their assigned PIVC device, and continued for each participant until the fluency criterion was achieved. Following achievement of fluency, participants were asked to perform PIVC using the untrained device (i.e., the PIVC device that they had not been trained on). RESULTS: All participants in both groups met the fluency criterion, and no significant differences were observed in the number of trials or total training required by groups to achieve fluency. Participants in both groups improved significantly from baseline (M = 11.69) to final training trial (M = 100). However, a significant decrement in performance (M = 81.5) was observed when participants were required to perform PIVC using the untrained device. CONCLUSIONS: Participants achieved fluency in PIVC regardless of the device used. However, significant decrements in performance were observed when participants were required to perform PIVC using a novel device. This finding supports the need for careful consideration of devices purchased and supplied in the clinical setting, and the need for training prior to the introduction of novel devices or for new staff members.

RESUMO

The risk of peripheral intravenous catheter failure varies according to the insertion site. This study examined catheter shape just after removal to evaluate the causes of catheter failure according to site. This study was a secondary analysis of previous study data. Our observational study was conducted during a 6-month period at The University of Tokyo Hospital. Participants were hospitalized adults who received infusion therapy via a short peripheral catheter. We acquired ultrasound images of blood vessels and surrounding tissues at the catheter insertion site before catheter removal and clinical images of the removed catheters. We analyzed 184 catheters from 142 participants. There were no significant differences in the catheter failure rate (29.9%) among insertion sites. Curvature in the middle of the catheter was present in 9.2% of cases; the median bend angle at the catheter base was 9.1° (range: 0.0°-68.3°). The bend angle of catheters inserted in the upper arm was significantly greater than of catheters in the forearm (p = 0.013). Catheter curvature was related to catheter failure (14.8% of failed catheters had curvature; p = 0.035) and occlusion (35.3% of occluded catheters had curvature; p = 0.008) in upper arm and forearm placements. The median distance from the elbow to the insertion site was shorter for failed catheters than for surviving catheters. To prevent catheter failure, especially occlusion resulting from catheter curvature, a catheter should be inserted at an appropriate insertion site far from the antecubital fossa.

RESUMO

Peripheral intravenous catheterization (PIVC) is frequently required for various medical treatments. Over 1 billion PIVC operations are performed per year in the United States alone. However, this operation is characterized by a very low success rate, especially amongst pediatric patients. Statistics show that only 53% of first PIVC attempts are successful in pediatric patients. Since their veins are small and readily rupture, multiple attempts are commonly required before successfully inserting the catheter into the vein. This article presents and evaluates a novel venous entry detection method based on measuring the electrical bio-impedance of the contacting tissue at the tip of a concentric electrode needle (CEN). This detection method is then implemented in the design of a clinical device called smart venous entry indicator (SVEI), which lights up a LED to indicate the venous entry when the measured value is within the range of blood. To verify this detection method, two experiments are conducted. In the first experiment, we measured the bio-impedance during the insertion of a CEN into a rat's tail vein with different excitation frequencies. Then three classifiers are tested to discriminate blood from surrounding tissues. The experimental results indicate that with 100 kHz excitation frequency the blood bio-impedance can be identified with accuracy nearly 100%, demonstrating the feasibility and reliability of the proposed method for venous entry detection. The second experiment aims to assess the impact of SVEI on PIVC performance. Ten naive subjects were invited to catheterize a realistic baby arm phantom. The subjects are equally divided into two groups, where one group does PIVC with SVEI and the other group uses an ordinary IV catheter. The results show that subjects using SVEI can achieve much higher success rates (86%) than those performing PIVC in a conventional way (12%). Also, all subjects assisted by SVEI succeeded in their first trials while no one succeed in their first attempt using the conventional unassisted system. These results demonstrate the proposed detection method has great potential to improve pediatric PIVC performance, especially for non-expert clinicians. This supports further investment towards clinical validation of the technology.

RESUMO

BACKGROUND: Peripheral intravenous catheterization (PIVC) is commonly performed on emergency departments and inpatient units. Unsuccessful PIVC first attempts increase pain, and lead to treatment and diagnostic delays. OBJECTIVE: To determine strategies associated with PIVC first attempt success in adult emergency department patients and inpatients. METHODS: We searched MEDLINE, EMBASE, CINAHL, TRIP, Cochrane Central Register of Controlled Trials (OVID), and grey literatures databases such as Proquest Dissertation and Theses Global, and Open Grey databases between November and December, 2014. The search was updated on January 28, 2016. We included full text reports of randomized controlled trials testing PIVC interventions versus standard of care. Risk of bias was assessed using the Cochrane Collaboration's tool. RESULTS: We included 14 randomized controlled trials involving 3201 participants. Interventions included the AccuVein™, AccuCath™ catheter system, ultrasound, safety catheters, and topical anesthetics. Three studies compared AutoGuard and Insyte catheters and were suitable for meta-analysis. There was no difference in first attempt success with a relative risk of 0.0 (95% CI, -0.04, 0.04). There was limited evidence to support the use of ultrasound to increase first attempt success. CONCLUSIONS: Well-designed and reported randomized controlled trials examining the effectiveness of ultrasound compared to standard of care are warranted.
