Comparison of four different techniques of i-gel insertion by anaesthesia trainees in children undergoing daycare surgery: A single-blind, randomised, comparative study.

Different techniques of i-gel insertion have been described with variable success rates. This study aimed to assess the incidence of malposition of i-gel in children with 90° rotation, 180° rotation, jaw thrust-assisted and standard insertion techniques. The study included 132 children undergoing elective surgery under general anaesthesia without neuromuscular blockade after approval from the Institutional Ethics Committee. The i-gel was inserted using one of the four randomised techniques (90° rotation, 180° rotation, jaw thrust-assisted insertion or standard insertion technique) by anaesthesia trainees. The primary objective of this study was to assess device malposition using three alternative techniques compared to the standard insertion technique by flexible video bronchoscopy. The incidence of malposition was the least in the 180° rotation technique group (27%) versus 39% in the standard and 90° rotation technique groups and 70% in the jaw thrust technique group (P = 0.004). Oropharyngeal leak pressure (OLP) was highest in the 180° rotation technique group, that is, 27.1 (5.3) cm H2O in the 180° rotation technique group versus 23 (4.3), 25.8 (4.1) and 24.7 (5.6) cm H2O in the standard, 90° rotation and assisted jaw thrust groups, respectively (P = 0.006). The time to i-gel insertion was the least with the standard insertion technique, that is, 16.9 (3.3) s, compared to 18.4 (3.1) s in the 90° rotation group, 19.5 (3.2) s in the180° rotation group and 20.1 (3.4) s in the assisted jaw thrust technique group (P < 0.001). The 180° rotation technique for i-gel placement in children by anaesthesia trainees has the lowest incidence of malposition and the best OLP versus other techniques but lacks any clear advantage in clinical performance and ventilation.

Symmetry-aware Neural Architecture for Embodied Visual Navigation

AbstractThe existing methods for addressing visual navigation employ deep reinforcement learning as the standard tool for the task. However, they tend to be vulnerable to statistical shifts between the training and test data, resulting in poor generalization over novel environments that are out-of-distribution from the training data. In this study, we attempt to improve the generalization ability by utilizing the inductive biases available for the task. Employing the active neural SLAM that learns policies with the advantage actor-critic method as the base framework, we first point out that the mappings represented by the actor and the critic should satisfy specific symmetries. We then propose a network design for the actor and the critic to inherently attain these symmetries. Specifically, we use G-convolution instead of the standard convolution and insert the semi-global polar pooling layer, which we newly design in this study, in the last section of the critic network. Our method can be integrated into existing methods that utilize intermediate goals and 2D occupancy maps. Experimental results show that our method improves generalization ability by a good margin over visual exploration and object goal navigation, which are two main embodied visual navigation tasks.

Influence of aging of PEEK attachment inserts on the pull-off force of implant-retained overdentures - A laboratory study.

The aim of the current study is to investigate the influence of mechanical stress as well as cleaning agents on the performance of various polyether ether ketone (PEEK) inserts for implant-retained overdentures (IOD). Three different standard PEEK inserts were subjected to rapid artificial aging through storage in chemical denture cleaning agents (acetic acid, sodium hypochlorite, or sparkling denture cleaner) as well as demineralized water. The pre-aged PEEK inserts were then placed in unilateral IOD and subjected to 200,000 chewing loads (5 kg ~ 50 N), with 5000 thermal cycles (5/55°C), and 1100 removal/insertion cycles (vertical movement 2 mm). For all the PEEK inserts, the retention forces decreased significantly with an increasing number of mechanical load cycles and after exposure to all the cleaning agents. PEEK inserts aged by exposure to chemical cleaning agents showed a significantly higher decline in retention force than the inserts stored in water. Confocal laser scanning microscopy indicated that the decline in retention force might be caused by wear on the internal insert surface in contact with the patrix. Within the limitations of this study, it can be concluded that the application of chemical cleaning agents accelerates the decline in the retention forces of PEEK retentive inserts in IODs.

Decreasing the incidence of central line-associated bloodstream infection in a medical intensive care unit: a best practice implementation project.

Bloodstream infections are common in critically ill patients using central venous access devices (CVAD) in intensive care units (ICU). This project aimed to decrease the incidence of central line-associated bloodstream infections (CLABSI) by using evidence-based strategies. The project applied the JBI audit and feedback methods. Thirty-two nurses and five resident physicians from the medical ICU of a medical center participated in the project. Preintervention compliance was measured for the 11 key evidence-based criteria (six audit criteria of central venous catheter insertion and five audit criteria of dressing and catheter securement). Strategies were implemented to overcome the barriers identified in the baseline assessment. Impact evaluation and sustainability were conducted to change the CLABSI rate and the competence of healthcare professionals in providing CVAD care. The JBI Practical Application of Clinical Evidence System and Getting Research into Practice audit tools were used for the data collection, analysis, and implementation planning. Barriers included insufficient knowledge among nurses and physicians, poor compliance with the standard CVAD insertion procedure by physicians, inadequate cooperation among the CVAD care team members, and lack of CVAD-related equipment. The strategies included education and training in CVAD care, the establishment of a team resource management program, and the provision of appropriate equipment. Following project implementation, the CLABSI rate decreased from 8.38 to 3.9 BSIs/1000 CVAD-days. The project successfully decreased the CLABSI rate and increased the competence of healthcare professionals. Implementation of best practices in clinical care should focus on leadership, team resource management, education, monitoring, and innovation.

Revisiting the Influence of Contact Length and Surrounding Medium on Metal Cutting Tribology

Metal cutting processes involve severe frictional conditions at the tool-chip contact interface, physico-chemical phenomena that are not fully understood and theoretical models with a strong empirical basis. In the literature, it is common to find values for the friction coefficient which are higher than the unit, despite the inconsistency of these findings with the mathematical theory of plasticity used for accurate modelling of the chip formation mechanics. Thus, the present work seeks to contribute to a better understanding of metal cutting tribology based on well-controlled and specially designed experimental conditions. To enable the stress state at the contact interface to be determined and to provide a known real contact area, polished cutting inserts with prepared rake faces were used to restrict the contact length in orthogonal cutting tests under controlled atmospheres. These conditions also allowed the contribution of the sticking mechanisms to be minimized. Cutting tools of restricted contact lengths have been found to reduce process forces and the friction coefficient, while industrial standard inserts make cutting operation sensitive to the chemical composition of the surrounding atmosphere.

Revisiting the Anatomical Landmark-Guided Central Venous Access Device Insertion: A Retrospective Cohort Study.

Ultrasound (USG) guidance is superior to blind and open cut-down techniques for accurate puncture of the internal jugular vein (IJV) or subclavian vein, but it increases the cost and duration of the procedure. Here, we report our experience with the reliability and consistency of anatomic landmark-guided technique for Central Venous Access Device (CVAD) insertion in a low-resource setting. A retrospective analysis of the prospectively maintained database of patients undergoing CVAD insertion through one of the jugular veins was performed. Central venous access was achieved using a standardized anatomic insertion landmark (apex of Sedillot's triangle). Ultrasonography (USG) and/or fluoroscopy assistance was taken as and when required. Over 12months (October 2021 to September 2022), a total of 208 patients underwent CVAD insertion. Central venous access was successfully achieved using anatomic landmark-guided technique in all but 14 patients (6.7%), in whom USG guidance or C-arm was used. Eleven out of 14 patients who needed guidance for CVAD insertion had body mass index (BMI) of more than 25, one had thyromegaly while the remaining two had an arterial puncture during cannulation. CVAD insertion-related complications included deep vein thrombosis (DVT) in five, extravasation of chemotherapeutic agent in one, spontaneous extrusion related to a fall in one, and persistent withdrawal-related occlusion in seven patients. Anatomical landmark-guided technique of CVAD insertion is safe and reliable, and can reduce the need for USG/C-arm in 93% of the patients.

To what extent is education for urinary catheter insertion and management offered to registered nurses in the United Kingdom?

AbstractRegistered nurses (RNs) competent in catheter insertion and management reduce catheter days and catheter associated urinary tract infections (CAUTIs). Guidelines suggest that education in catheter insertion and management should occur regularly to ensure competency. However, there is no evidence to suggest this occurs in the United Kingdom. The databases Cinahl and Medline databases and the grey literature were searched and revealed that CAUTIs account for ~40% of hospital acquired infections and are associated with increased mortality, morbidity, length of stay and hospital costs. Prevalence, however, can be reduced if all evidence‐based measures in insertion and management are carried out. The literature review demonstrated that clinical catheter related education improves nurses' knowledge which, translated into behaviour, results in reduced catheter days and CAUTI rates. A pragmatic, descriptive mixed methods convergent parallel approach was used to survey RNs from two professional associations through their mailing lists and social media platforms, using an online Qualtrics™ questionnaire. An online survey method was chosen to maximize geographical reach. Respondents confirmed their consent on accessing the online survey prior to commencing the questionnaire. All participants and their responses were anonymous. Results were saved on the Qualtrics™ platform and analysed quantitatively using descriptive statistics and qualitatively using a pragmatic approach to thematic analysis. Of the 72 responses, 61% (n = 44) worked in an acute hospital and 47% (n = 34) worked in the London area. There was representation from all over the United Kingdom except Scotland. 96% (n = 69) RNs were offered education in catheter insertion and management. Content of education included theory, practical, competency and ongoing education. 51% (n = 36) were offered education on a frequent basis. The results indicated that education in catheter insertion and management for RNs in the United Kingdom is not standardized. This may have implications for patient outcome measures such as CAUTI and on a macro level may be a symptom of wider organizational cultural inadequacies. Future research could inform the design of a standardized catheter insertion and management education package and measure its effect and impact on practice. The sampling method and subsequent response rate was a limitation of this study, and it may have been appropriate to use a more generic sampling frame to achieve representative results.

Damage Analysis of CFRP Hybrid Bonded-Bolted Joint during Insertion of Interference-Fit Bolt.

In this study, experiments and finite element analysis (FEA) were used to evaluate the impact of interference-fit sizes on CFRP hybrid bonded-bolted (HBB) joint damage during bolt insertion. The specimens were designed in accordance with the ASTM D5961 standard and bolt insertion tests were performed at selected interference-fit sizes (0.4%, 0.6%, 0.8%, and 1%). Damage to composite laminates was predicted using the Shokrieh-Hashin criterion and Tan's degradation rule via the user subroutine USDFLD, while damage to the adhesive layer was simulated by the Cohesive Zone Model (CZM). The corresponding bolt insertion tests were performed. The variation of insertion force with interference-fit size was discussed. The results showed that matrix compressive failure was the main failure mode. With the growth of the interference-fit size, more failure modes appeared, and the failure region expanded. Regarding the adhesive layer, it did not completely fail at the four interference-fit sizes. This paper will be helpful in designing composite joint structures and especially for understanding CFRP HBB joint damage and failure mechanisms.

The hybrid permanent cardiac pacing in a patient with high infection risk

Infective complications of permanent cardiac pacing severely influence long-term outcomes despite system removal and targeted antibiotics. In-hospital mortality reaches 4,6 % and 1-year 14-17%. A case of a 68-year-old patient was described. The patient suffered from infective endocarditis, which caused the extraction of a formerly implanted standard dual-chamber pacemaker and insertion of bioprosthesis of the aortic valve and epicardial DDD system implantation. After 9 years during follow-up increase of impedance and threshold on ventricular lead have been observed. Due to temporal pacemaker dependency, the decision was made to implant a leadless MICRA AV device with preservation of active atrial pacing through an epicardial DDD system programmed to AAI mode. No procedural complications were observed. There was no electrical interference between implanted systems.

Dynamic Behavior and Insertional Forces of a Precurved Electrode Using the Pull-Back Technique in a Fresh Microdissected Cochlea.

This study evaluated the utility of the pull-back technique in improving perimodiolar positioning of a precurved cochlear implant (CI) electrode array (EA) with simultaneous insertion force profile measurement and direct observation of dynamic EA behavior. Precurved EAs with perimodiolar positioning have improved outcomes compared with straight EAs because of lowered charge requirements for stimulation and decreased spread of excitation. The safety and efficacy of the pull-back technique in further improving perimodiolar positioning and its associated force profile have not been adequately demonstrated. The bone overlying the scala vestibuli was removed in 15 fresh cadaveric temporal bones, leaving the scala tympani unviolated. Robotic insertions of EAs were performed with simultaneous force measurement and video recording. Force profiles were obtained during standard insertion, overinsertion, and pull-back. Postinsertion CT scans were obtained during each of the three conditions, enabling automatic segmentation and calculation of angular insertion depth, mean perimodiolar distance ( Mavg ), and cochlear duct length. Overinsertion did not result in significantly higher peak forces than standard insertion (mean [SD], 0.18 [0.06] and 0.14 [0.08] N; p = 0.18). Six temporal bones (40%) demonstrated visibly improved perimodiolar positioning after the protocol, whereas none worsened. Mavg significantly improved after the pull-back technique compared with standard insertion (mean [SD], 0.34 [0.07] and 0.41 [0.10] mm; p < 0.01). The pull-back technique was not associated with significantly higher insertional forces compared with standard insertion. This technique was associated with significant improvement in perimodiolar positioning, both visually and quantitatively, independent of cochlear size.

Keller Funnel Efficacy in "No Touch" Breast Augmentation and Reconstruction: A Systematic Review.

A systematic review of PubMed, Embase, the Cochrane database, and Google Scholar was performed between 2005 and 2021. All clinical-based, retrospective and prospective studies utilizing the Keller funnel method for breast implant insertion were selected. Six studies were identified for evaluation: five were retrospective cohorts and one was a prospective trial. No randomized controlled trials were found. Outcomes reported included lower rates of capsular contracture (RR, 0.42; P = 0.0006; 95% CI, 0.25-0.69), shorter incision lengths (35.5 ± 2.1 mm), less insertion time (mean = 6 seconds), and decreased complications, and one paper reported ultimately greater patient satisfaction with outcomes (BREAST-Q Score: 92%). This review suggests that the Keller funnel is a useful method for no-touch breast augmentation and reconstruction surgery. The Keller funnel reduces subsequent capsular contracture rate, surgical time, and incision length and allows for easier insertion. However, our findings support recommendation of a prospective randomized controlled clinical trial with larger population size and follow-up intervals.

A Comparison of Wear Patterns on Retrieved and Simulator-Tested Total Knee Replacements.

Aseptic implant loosening is the most common reason for revision surgery after total knee replacement. This is associated with adverse biological reactions to wear debris from the articulating implant components. To predict the amount of wear debris generated in situ, standard wear testing of total knee replacement (TKR) is carried out before its clinical use. However, wear data reported on retrievals of total knee replacement (TKR) revealed significant discrepancies compared with standard wear simulator studies. Therefore, the aim of the present study was to compare the wear patterns on identical posterior-cruciate-retaining TKR designs by analyzing retrieved and experimentally tested implants. The identification and classification of wear patterns were performed using 21 retrieved ultra-high-molecular-weight-polyethylene (UHMW-PE) inserts and four sets of inserts of identical design and material tested in a knee wear simulator. These four sets had undergone different worst-case conditions and a standard test in a wear simulator according to ISO 14243-1. Macroscopic and microscopic examinations of the polyethylene inserts were performed, including the determination of seven modes of wear that correspond to specific wear patterns, the calculation of wear areas, and the classification of the damage over the whole articulating area. Retrieved and standard wear simulator-tested UHMW-PE inserts showed significant differences in wear area and patterns. The total wear areas and the damage score were significantly larger on the retrievals (52.3% versus 23.9%, 32.7 versus 22.7). Furthermore, the range of wear patterns found on the retrievals was not reproducible in the simulator-tested inserts. However, good correspondence was found with the simulator-tested polyethylene inserts under worst-case conditions (third body wear), i.e., deep wear areas could be replicated according to the in vivo situation compared with other wear test scenarios. Based on the findings presented here, standard simulator testing can be used to directly compare different TKR designs but is limited in the prediction of their in situ wear. Preclinical wear testing may be adjusted by worst-case conditions to improve the prediction of in situ performance of total knee implants in the future.

P077Pilot study on a novel, alternative subdermal scapular insertion site for the etonogestrel contraceptive implant

<h3>Objectives</h3> To assess the pharmacokinetics and pharmacodynamics of the etonogestrel (ENG) contraceptive implant when inserted at an alternative scapular site. <h3>Methods</h3> We conducted a pilot study of healthy, reproductive-aged women who underwent subdermal insertion of an ENG implant over the inferior edge of the non-dominant scapula (scapular insertion). We measured serum ENG levels over one year at nine time points. Participants completed questionnaires on insertion site and bleeding side effects. We collected photographs and video recordings of insertion and removal techniques. <h3>Results</h3> We enrolled five participants (as prespecified): Their median age was 26.0 (range, 19.6–30.3) and their median BMI was 25.0 kg/m2 (range, 22.0–28.0). Among five scapular implant users, all serum ENG concentrations remained >90 pg/mL during the first year of use and demonstrated bioequivalence with published data for arm insertion of ENG implant at all time points. The mean serum ENG level was 511.7±168.2 pg/mL at one week and 130.3± 19.1 pg/mL at 12 months. During the first week of insertion, four of five participants noted insertion site pain with a median pain score of 2 (range, 1–3), but all noted resolution by week two. Participants reported bleeding patterns similar to standard ENG implant use. At the end of the study, all participants were satisfied with the implant and would recommend scapular insertion to a friend. <h3>Conclusions</h3> Scapular insertion of the ENG contraceptive implant has bioequivalent pharmacokinetics to arm insertion over one year of use. This novel, alternative site was well tolerated and demonstrated similar bleeding side effects to standard arm insertion.

Design evaluation of disk-type milling cutter with special inserts applying analytical simulation and the experimental verification in screw rotor milling

A milling cutter with inserted blades is designed for each screw rotor since the geometry profile is unique, corresponding to its purposes and function. Correctness in cutter design, including the cutting-edge insert profile, is necessary to achieve a precise rotor profile; therefore, it is essential to introduce an enhanced cutter design. This study proposes a design of a disk-type milling cutter with special inserts. The insert cutting edge was generated on the axial plane considering the cutter curve curvature and then positioned onto the cutter body according to the modified coordinate system with a revolve angle. The analytical cutting result indicates that the simulated profile is relatively even along the gear tooth profile and the normal deviation is significantly tinier than the insert arrangement area. In addition, the cutter design applying special inserts acquires better results than standard inserts. Finally, the experimental result, including the rotor surface topography, confirms that the proposed cutter design is reliable and realistic in CNC screw rotor milling.

Thicker polyethylene inserts (≥ 13 mm) increase the risk for early failure after primary cruciate-retaining total knee arthroplasty (TKA): a single-centre study of 7643 TKAs

PurposeThis study investigates whether thicker (PE) inserts lead to a greater risk for revision after TKA. The differences between the TKA designs of three manufacturers (NexGen, PFC Sigma, Triathlon) are also compared.MethodsA total of 7643 primary TKA surgeries were included. PE inserts were divided into two groups—“thick PE inserts” with a thickness of 13 mm (mm) or more and “standard PE inserts” with a thickness of less than 13 mm. Three cruciate-retaining (CR) TKA designs (NexGen, PFC Sigma, Triathlon) were included in the study. The differences in failure rates between groups were investigated using Kaplan–Meier survival curves and Cox regression model with hazard ratios (HR). Failure rates were investigated short-term (< 2 years) and long-term (the whole follow-up period). The TKA designs were analysed both together and separately.ResultsDuring the whole follow-up period, there were 184 (2.4%) aseptic revisions. The thick PE insert group showed an increased risk for revision compared to the standard PE insert group in both short-term (< 2 years; HR 2.0, CI 1.3 to 3.2) and long term (> 2 years; HR 1.6, CI 1.1 to 2.3) follow-up. The highest revision rate was observed in patients who received the Triathlon TKA with a thicker PE insert (HR 2.6, CI 1.2 to 5.7).ConclusionThe results indicate that thicker PE inserts are associated with increased risk for revision in primary TKA. Further research is required to ascertain whether more conformed PE inserts or constrained knee designs instead of thick CR inserts will ultimately lead to better clinical outcomes.Level of evidenceIII.

The Vacuum Cherenkov Detector (VCD) for γ-ray measurements in inertial confinement fusion experiments.

Inertial confinement fusion experiments at both the National Ignition Facility (NIF) and the Laboratory for Laser Energetics OMEGA laser facility currently utilize Cherenkov detectors, with fused silica as the Cherenkov medium. At the NIF, the Quartz Cherenkov Detectors improve the precision of neutron time-of-flight measurements; and at OMEGA, the Diagnostic for Areal Density provides measurements of capsule shell areal densities. An inherent property of fused silica is the radiator's relatively low energy threshold for Cherenkov photon production (Ethreshold < 1MeV), making it advantageous over gas-based Cherenkov detectors for experiments requiring low-energy γ detection. The Vacuum Cherenkov Detector (VCD) has been specifically designed for efficient detection of low energy γ's. Its primary use is in implosion experiments, which will study reactions relevant to stellar and big-bang nucleosynthesis, such as T(4He,γ)7Li, 4He(3He,γ)7Be, and 12C(p,γ)13N. The VCD is compatible with LLE's standard Ten-Inch Manipulator diagnostic insertion module. This work will outline the design and characterization of the VCD as well as provide results from recent experiments conducted at the OMEGA laser facility.

An Anatomic Study of the Proximal Tibial Epiphysis With Relevance to Percutaneous Epiphysiodesis Using Transphyseal Screws (PETS).

Percutaneous epiphysiodesis using transphyseal screws (PETS) is a common procedure to correct lower extremity limb-length discrepancies in the pediatric population. A potential complication of this procedure is development of tibial valgus deformity, which may occur secondary to decreased screw purchase in the thinner medial proximal tibial epiphysis. The thickness of the proximal tibial epiphysis has not yet been well quantified, which was the aim of this study. Three-dimensional surface scans of 32 cadaveric proximal tibial epiphyses in specimens aged 3 to 17 years old were obtained and computer modeling software was utilized to measure the thickness of the proximal tibial epiphysis at 20 standardized potential screw insertion points according to a generated 5×4 map. When normalized to the total width of the proximal tibial epiphysis, the lateral side is thicker compared with the medial side. The positions with the greatest thickness are located at the midline in the sagittal plane and 33% of the total physeal width away from the medial and lateral edges in the coronal plane (0.265 and 0.261 normalized thickness, respectively). The proximal tibial epiphysis is particularly thin 25% from the medial edge (normalized thickness range: 0.196 to 0.221). Multiple regression analysis revealed a significant relationship between increasing age and female sex with thinner normalized medial and lateral heights. During PETS, areas for greater screw purchase are located centrally in the sagittal plane and 33% of the total width away from the medial and lateral edges of the proximal tibial epiphysis in the coronal plane. Caution should be taken when inserting screws in the medial 25% of the proximal tibial epiphysis as it is thinner relative to the lateral edge, particularly in females. This study provides quantitative, anatomic data on the thickness of the proximal tibial epiphysis, which can direct screw placement during PETS for correcting limb-length discrepancies. These data may help lessen the risk of developing tibial valgus deformity although future clinical studies are necessary to fully evaluate this possibility.

Prediction of EMI Filter Attenuation in Power-Electronic Converters via Circuit Simulation

This article investigates the conducted-emission (CE) suppression characteristics of electromagnetic interference (EMI) filters used in power-electronic equipment by time-domain circuit simulation. An operational definition of insertion attenuation is introduced by comparing the CE in the absence and in the presence of the EMI filter. For the sake of exemplification, the analysis focuses on switched-mode dc–dc converters. It is shown that the EMI-filter attenuation behaves differently from the standard insertion loss (IL) and exhibits peculiar properties in these circuits. Namely, its response is known at discrete frequencies where the converter generates CE and may strongly depend on the harmonic index so to jump between quite different levels from a harmonic component to the next one, with a pseudoperiodic behavior, which can be related to the duty cycle. This effect is caused by circuit nonlinearity and is partially mitigated if the simulation accounts for two practically relevant aspects: random instability of the duty cycle and resolution bandwidth of the EMI receiver. The dependence of the common-mode (CM) and differential-mode attenuations on the loading conditions and duty cycle is analyzed, and it is shown that linear IL models provide reasonable predictions of CM attenuation only. Finally, experimental evidence of the unveiled phenomena is presented.

The effect of new device on pain and comfort levels in individuals undergoing peripheral intravenous cannula insertion.

The purpose of this study is to see how ShotBlocker® affects the pain and comfort level associated with short peripheral intravenous cannula (PIV) insertion. The study was conducted on a single sample group using a pre-post design. Individuals in the sample group who underwent a brief PIV insertion procedure served as both the study's control and intervention groups. In the sample group, the same nurse inserted a peripheral intravenous catheter into the cephalic veins of the right and left forearms using a standard insertion and ShotBlocker®. The pain and comfort levels were assessed using the VAS and Comfort Scale. When the distribution of the average pain and comfort scores of the individuals treated with the peripheral intravenous catheter was examined, it was found that the average pain score of the peripheral intravenous catheter insertion using ShotBlocker® was statistically significantly lower than the peripheral intravenous catheter insertion using the standard method, and the comfort score averages were statistically higher. When the correlation between the pain and comfort score averages of individuals undergoing peripheral intravenous catheter insertions was investigated, a statistically significant and strong negative relationship (p = 0.001) was discovered. As a result, the use of ShotBlocker® during the short PIV insertion procedure is an effective method to reduce the pain caused by the peripheral intravenous catheter. It was determined that the comfort level of the individuals increased as the pain due to peripheral intravenous catheter insertion decreased.
