Nine treatments of 1000 mL therapeutic phlebotomy in a subject with polycythemia: A case report.

Large-volume therapeutic phlebotomy is the mainstay of hemochromatosis treatment and offers an opportunity to investigate the hemodynamic changes during acute hypovolemia. An otherwise healthy 64-year-old male with hemochromatosis participated. On nine separate visits, 1000 mL therapeutic phlebotomy was performed. On one occasion, pre- and post-phlebotomy orthostatic challenge with 27° reverse Trendelenburg position was administered. Mean arterial pressure, heart rate, and stroke volume were measured continuously during the procedures. The patient's tolerance to the interventions was continuously evaluated. The procedures were well tolerated by the patient. Mean arterial pressure was maintained during hemorrhage and following phlebotomy in both supine and reverse Trendelenburg positions, primarily through an increase in heart rate and systemic vascular resistance. The present study found that 1000 mL therapeutic phlebotomy in a patient with hemochromatosis may be acceptably and safely used to model hemorrhage. The approach demonstrates high clinical applicability and ethically robustness in comparison with volunteer studies.

Ultrasound-Guided Peripheral Venipuncture Decreases the Procedure's Pain and Positively Impacts Patient's Experience: The PRECISE Randomized Clinical Trial.

This study aimed to compare patients' experience of pain during ultrasound (US)-guided peripheral venipuncture versus conventional peripheral venipuncture. This randomized clinical trial was conducted at a public university hospital in 2021. Adult patients with indication for intravenous therapy compatible with peripheral intravenous catheters (PIVCs) were included: intervention group (IG), US peripheral venipuncture executed by specialist nurses; control group (CG), conventional peripheral venipuncture executed by clinical practice nurses. The primary outcome was patient experience of pain during the procedure and patient experience related to the PIVC placement method. Sixty-four patients were included, 32 for each group. The pain experienced was none-to-mild in the IG for 25 patients (78.1%) and moderate-to-severe in the CG for 21 patients (65.7%; P < .001). The overall pain rating was 2 (1-3) in the IG and 4 (3-6) in the CG (P < .001). The recommendation of the procedure in IG (net promoter score [NPS] + 90.6%) versus CG (NPS + 18.8%) was considered excellent and good, respectively (P < .001). Patients had less pain and significantly recommended the US-guided procedure. Patient experience with US-guided PIVC, performed by a specialist nurse, was superior to that of conventional peripheral venipuncture.

Feasibility, acceptability, and safety of a novel device for self-collecting capillary blood samples in clinical trials in the context of the pandemic and beyond.

BACKGROUND: Home blood self-collection devices can enable remote monitoring, but their implementation requires validation. Our objectives were to explore (i) the impact of sampling sites and topical analgesia on capillary blood volume and pain perception and (ii) the safety, acceptability, and failure of capillary self-collection among adults and children using the Tasso-SST device. METHODS: We conducted a two-phase study. The investigational phase consisted of two on-site cross-sectional studies in healthy adult participants (≥ 12 years) and children (1-17 years) with their accompanying parent. Adults received 4 capillary samplings, where puncture sites and topical analgesia were randomized in a factorial design, and a venipuncture; children (and one parent) had one capillary sampling. The two co-primary outcomes were blood volume and pain. The implementation phase was conducted in two multicentre trials in participants choosing remote visits; blood volume, collection failure, adverse events, and satisfaction were documented. RESULTS: In the investigational phase, 90 participants and 9 children with 7 parents were enrolled; 15 adults and 2 preschoolers participated in the implementation phase. In the adult investigational study, the device collected a median (25%, 75%) of 450 (250, 550) µl of blood with no significant difference between the puncture site, topical analgesia, and its interaction. Using topical analgesia reduced pain perception by 0.61 (95% CI: 0.97, 0.24; P <0.01) points on the 11-point scale; the pain reduction varied by puncture site, with the lower back showing the most significant decrease. Overall, combining all studies and phases, the median volume collected was 425 (250, 500) µl, and the device failure rate was 4.4%; minor adverse effects were reported in 8.9% of the participants, all were willing to use the device again. CONCLUSION: Capillary blood self-collection, yielding slightly less than 500 µl, proves to be a safe and relatively painless method for adults and children, with high satisfaction and low failure rates. The puncture site and topical analgesia do not affect blood volume, but topical analgesia on the lower back could reduce pain.

A survey on the practice of phlebotomy in Lithuania and adherence to the EFLM-COLABIOCLI recommendations: continuous training and clear standard operating procedures as tools for better quality.

Introduction: The aim of this study was to determine the level of compliance of venous blood sampling (VBS) in Lithuania with the joint recommendations of the European Federation of Clinical Chemistry and Laboratory Medicine and the Latin American Confederation of Clinical Biochemistry (EFLM-COLABIOCLI) and to analyse possible causes of errors. A survey was conducted between April and September 2022. Materials and methods: A self-designed questionnaire was distributed to the Lithuanian National Societies. Error frequencies and compliance score were computed. Differences between groups were analysed using Pearson's chi-square, Fisher's exact criterion, Mann-Whitney U (for two groups), or Kruskal-Wallis (for more than two groups) for categorical and discrete indicators. The association between ordinal and discrete variables was assessed using Spearman's rank correlation coefficient. Statistical significance was determined at P < 0.05. Results: A total of 272 respondents completed the questionnaire. Median error rate and compliance score were 31.5% and 13/19, respectively. Significant differences were found among professional titles, standard operating procedures availability, training recency, and tourniquet purpose opinions. A negative correlation was noted between compliance and time since training (rs = - 0.28, P < 0.001). Conclusions: The findings of this study indicate that there is a significant need for improvement in compliance with the EFLM-COLABIOCLI recommendations on VBS among specialists in Lithuania. Essential measures include prioritizing ongoing phlebotomy training and establishing national guidelines. Harmonisation of blood collection practices across healthcare institutions is crucial.

A Dried Blood Spot protocol for high-throughput quantitative analysis of SARS-CoV-2 RBD serology based on the Roche Elecsys system.

SARS-CoV-2 spreads pandemically since 2020; in 2021, effective vaccinations became available and vaccination campaigns commenced. Still, it is hard to track the spread of the infection or to assess vaccination success in the broader population. Measuring specific anti-SARS-CoV-2 antibodies is the most effective tool to track the spread of the infection or successful vaccinations. The need for venous-blood sampling however poses a significant barrier for large studies. Dried-blood-spots on filter-cards (DBS) have been used for SARS-CoV-2 serology in our laboratory, but so far not to follow quantitative SARS-CoV-2 anti-spike reactivity in a longitudinal cohort. We developed a semi-automated protocol or quantitative SARS-CoV-2 anti-spike serology from self-sampled DBS, validating it in a cohort of matched DBS and venous-blood samples (n = 825). We investigated chromatographic effects, reproducibility, and carry-over effects and calculated a positivity threshold as well as a conversion formula to determine the quantitative binding units in the DBS with confidence intervals. Sensitivity and specificity reached 96.63% and 97.81%, respectively, compared to the same test performed in paired venous samples. Between a signal of 0.018 and 250 U/mL, we calculated a correction formula. Measuring longitudinal samples during vaccinations, we demonstrated relative changes in titers over time in several individuals and in a longitudinal cohort over four follow-ups. DBS sampling has proven itself for anti-nucleocapsid serosurveys in our laboratory. Similarly, anti-spike high-throughput DBS serology is feasible as a complementary assay. Quantitative measurements are accurate enough to follow titer dynamics in populations also after vaccination campaigns.

To determine the prevalence of SARS-CoV-2 antibodies among populations, the most effective public health tool is measuring specific anti-SARS-CoV-2 antibodies induced by infection or vaccination. However, conducting large-scale studies that involve venous-blood sampling is challenging due to the associated feasibility and cost issues. A more cost-efficient and less invasive method for SARS-CoV-2 serological testing is using Dried-Blood-Spots on filter cards (DBS). In this paper, we have developed a semi-automated protocol for quantifying SARS-CoV-2 anti-spike antibodies from self-collected DBS. Our laboratory has previously successfully used DBS sampling for anti-nucleocapsid antibody surveys. Likewise, conducting high-throughput DBS serology for anti-spike antibodies is feasible as an additional test that can be performed using the same sample preparation as the anti-nucleocapsid analysis. The quantitative measurements obtained are accurate enough to track the dynamics of antibody levels in populations, even after vaccination campaigns.

Challenges of Post-Venipuncture Jugular Venous Thrombosis in Patients with Secondary Hyperparathyroidism: A Case Report.

BACKGROUND Hyperparathyroidism is a common issue in patients on long-term hemodialysis, necessitating parathyroidectomy with deep venipuncture. These patients frequently exhibit a heightened incidence of vascular calcification, complicating deep venipuncture and increasing the risk of associated complications. Therefore, a crucial aspect of preoperative assessment in this population involves identifying vascular calcification, with a preference for ultrasound-guided intraplane puncture. Special care is required to prevent blood vessel injuries and postoperative complications such as deep vein thrombosis. CASE REPORT We present the case of a 66-year-old woman with secondary hyperparathyroidism who encountered challenges during an internal jugular vein puncture, leading to subsequent thrombosis. Initial attempts were hindered by calcification of the internal jugular vein's vascular wall, resulting in stratified damage to the vessel's wall. However, the ultrasound-guided in-plane puncture technique successfully allowed the insertion of a central venous catheter without further damage to the vascular wall. On the postoperative fourth day, thrombus formation was observed in the damaged vascular wall from the initial puncture. CONCLUSIONS The ultrasound-guided in-plane puncture technique is advantageous in overcoming the difficulties associated with puncturing through deep vein calcification in patients with secondary hyperparathyroidism. This technique also diminishes the likelihood of complications such as venous thrombosis.

Iatrogenic blood loss from phlebotomy during adult extracorporeal membrane oxygenation: A retrospective cohort study.

BACKGROUND: Adult extracorporeal membrane oxygenation (ECMO) patients are at high risk for allogeneic blood transfusion. Few studies have characterized iatrogenic blood loss from phlebotomy in adult ECMO patients. We hypothesized that iatrogenic phlebotomy would be a significant source of blood loss during ECMO. METHODS: Adults who had their entire ECMO run at our medical center between 2020 and 2022 were included. Average daily phlebotomy volume and total phlebotomy volume during ECMO were estimated based on the total number of laboratory tests that were processed. In addition, the crude and adjusted association between total phlebotomy volume during ECMO and RBC transfusion during ECMO was evaluated using linear regression and Loess curve analysis. RESULTS: A total of 161 patients who underwent 162 ECMO runs were included. Of the 162 ECMO runs, 88 (54.3%) were veno-arterial and 74 (45.7%) were veno-venous ECMO. Median duration of ECMO was 5 days [25th, 75th percentile = 2, 11]. Median daily phlebotomy volume was 130 mLs [25th, 75th percentile = 94, 170] and median total phlebotomy volume during ECMO was 579 mLs [25th, 75th percentile = 238, 1314]. There was a significant crude and adjusted association between total phlebotomy volume and RBC transfusion during ECMO (beta coefficient = 0.0023 and 0.0024 respectively, both p < .001) based on linear regression analysis. DISCUSSION: Phlebotomy for laboratory testing is a significant source of blood loss during ECMO in adults. Comprehensive patient blood management for adult ECMO patients should include strategies to reduce laboratory testing and/or phlebotomy volume during ECMO.

Evaluation of a scoring system for vein suitability in platelet apheresis donors.

INTRODUCTION: Donor vein assessment for the selection of good quality veins is crucial for a successful apheresis procedure. This study intends to find out the effectiveness of a vein assessment scoring tool (VST) used and found to be effective in selecting whole blood donors to reduce the difficulty in identifying good quality veins for the plateletpheresis procedure. MATERIALS AND METHODS: This was a prospective observational study on platelet apheresis donors with the application of a VST consisting of three vein descriptor parameters (vein visibility, vein palpability, and vein size) with 5 Likert-type responses constituting a score of 0-12 for each arm. Two vein assessors independently evaluated the vein in both arms and marked their responses blinded from each other as well from the principal investigator. The scores were then calculated and analyzed at the end of the study for their association with phlebotomy and procedural outcomes. RESULTS: A total of 190 donors were recruited. The mean scores for the arms with successful and failed phlebotomy were 9.1 and 9.4 (SD 2.3), respectively. The intra-class correlation Alpha Cronbach value was 0.834 and 0.837 for total scoring in the left arm and right arm, respectively, between the two assessors. Scores neither showed a correlation with other outcomes like low flow alarms, hematoma formation, number of phlebotomy attempts, and procedure completion. CONCLUSION: The study showed that the vein score tool did not truly predict the phlebotomy outcome in apheresis donors, though there was a good degree of inter-assessor reliability.

Evaluating Nursing Students' Venipuncture and Peripheral Intravenous Cannulation Knowledge, Attitude, and Performance: A Two-Phase Evaluation Study.

Peripheral intravenous cannulation and venipuncture are among the most common invasive procedures in health care and are not without risks or complications. The aim of this study was to evaluate the current training provided to nursing and midwifery undergraduate students. Student knowledge, attitude, practice, and performance regarding these procedural skills were assessed. A knowledge, attitude, and practices survey was disseminated to final year nursing and midwifery students as the first phase of this study. For the second phase of the study, nursing students were video recorded and then observed performing the skill of peripheral intravenous cannulation in a simulated environment. Thirty-eight nursing and midwifery students completed the survey, and 66 nursing students participated in the observation study. Descriptive statistics were performed. The mean knowledge score was 7.2 out of 15.0, (standard deviation [SD] = 2.4), and the mean attitude score was 10.20 out of 18.00 (SD = 4.79). Qualitative data from the survey were categorized to demonstrate specific areas of focus for improving the training. The mean performance score was 16.20 out of 28.00 (SD = 2.98). This study provides valuable input to developing and enhancing evidence-based curricula. It can help educators and supervisors, in both academic and clinical settings, identify areas where clinical performance and education could be enhanced.

Phlebotomy-free days in children hospitalized with common infections and their association with clinical outcomes.

BACKGROUND: Phlebotomy for hospitalized children has consequences (e.g., pain, iatrogenic anemia), and unnecessary testing is a modifiable source of waste in healthcare. Days without blood draws or phlebotomy-free days (PFDs) has the potential to serve as a hospital quality measure. OBJECTIVE: To describe: (1) the frequency of PFDs in children hospitalized with common infections and (2) the association of PFDs with clinical outcomes. DESIGN, SETTINGS AND PARTICIPANTS: We performed a cross-sectional study of children hospitalized 2018-2019 with common infections at 38 hospitals using the Pediatric Health Information System database. We included infectious All Patients Refined Diagnosis Related Groups with a median length of stay (LOS) >2 days. We excluded patients with medical complexity, interhospital transfers, those receiving intensive care, and in-hospital mortality. MAIN OUTCOME AND MEASURES: We defined PFDs as hospital days (midnight to midnight) without laboratory blood testing and measured the proportion of PFDs divided by total hospital LOS (PFD ratio) for each condition and hospital. Higher PFD ratios signify more days without phlebotomy. Hospitals were grouped into low, moderate, and high average PFD ratios. Adjusted outcomes (LOS, costs, and readmissions) were compared across groups. RESULTS: We identified 126,135 encounters. Bronchiolitis (0.78) and pneumonia (0.54) had the highest PFD ratios (most PFDs), while osteoarticular infections (0.28) and gastroenteritis (0.30) had the lowest PFD ratios. There were no differences in adjusted clinical outcomes across PFD ratio groups. Among children hospitalized with common infections, PFD ratios varied across conditions and hospitals, with no association with outcomes. Our data suggest overuse of phlebotomy and opportunities to improve the care of hospitalized children.

Effect of using smaller blood volume tubes and closed blood collection devices on total blood loss in patients undergoing major cardiac and vascular surgery.

BACKGROUND: Diagnostic laboratory tests are an integral part of managing hospitalized patients. In particular, patients in the intensive care units (ICUs) can experience a concerning amount of blood loss due to diagnostic testing, which can increase the risk developing iatrogenic anemia. Several interventions exist to curtail avoidable blood loss, for example computerized decision support, smaller phlebotomy tubes, and other blood conservation devices. Nevertheless, use of these interventions is not standardized. Therefore, the objective of our study was to quantify the daily phlebotomy volume taken from patients who had undergone major cardiac or vascular surgery. METHODS: We estimated the number of blood analyses and volumes of drawn blood of 400 consecutive patients (≥ 18 yr) undergoing major cardiac or vascular surgery. The amount of blood saved using small-volume tubes and in combination with blood conservation device rather than standard-volume tubes was estimated for serum chemistry (serum), ethylenediaminetetraacetic acid (EDTA) tubes, sodium citrate coagulation (SCC) tubes, and arterial blood gas (ABG) analysis. RESULTS: The mean total blood loss due to phlebotomy drawing using standard-volume tubes during hospitalization was 167.9 mL (95% confidence interval [CI], 158.0 to 177.8), 255.6 mL (95% CI, 226.5 to 284.6), and 695.3 mL (95% CI, 544.1 to 846.4) for patients undergoing cardiac surgery with a hospital length of stay (LOS) of 0-10, 11-20, and ≥ 21 days, respectively. The mean total blood loss due to phlebotomy during hospitalization was 80.5 mL (95% CI, 70.5 to 90.6), 225.0 mL (95% CI, 135.1 to 314.8 mL) and 470.3 mL (95% CI, 333.5 to 607.1) for vascular surgery patients with LOS 0-10, 11-20, and ≥ 21 days, respectively. Patients with at least a two-day stay at the ICU had a mean blood loss of 146.6 mL (95% CI, 134.6 to 158.6 mL) and those with ≥ 11 days incurred a loss of 1,428 mL (95% CI, 1,117.8 to 1,739.2). The use of closed blood collection device and small-volume tubes (serum, EDTA, SCC, and ABG) reduced blood loss by 82.8 mL for patients with an ICU stay of 2 days and up to 824.0 mL for patients with a ICU stay of ≥ 11 days. CONCLUSION: Diagnostic laboratory tests are associated with significant patient blood loss, but are a modifiable risk factor. The use of small-volume tubes and closed blood collection devices decreases the volume of patient blood drawn for analysis and prevents blood waste.

RéSUMé: CONTEXTE: Les tests diagnostiques de laboratoire font partie intégrante de la prise en charge des personnes hospitalisées. Plus spécifiquement, la patientèle des unités de soins intensifs (USI) peut perdre une quantité inquiétante de sang en raison des tests de diagnostic, ce qui peut augmenter le risque d'anémie iatrogène. Plusieurs interventions existent pour réduire les pertes de sang évitables, par exemple une aide à la décision informatisée, des tubes de phlébotomie plus petits et d'autres dispositifs de conservation du sang. Néanmoins, le recours à ces interventions n'est pas normalisé. Par conséquent, l'objectif de notre étude était de quantifier le volume quotidien de phlébotomie prélevée chez des patient·es ayant bénéficié d'une chirurgie cardiaque ou vasculaire majeure. MéTHODE: Nous avons estimé le nombre d'analyses sanguines et les volumes de sang prélevés de 400 personnes consécutives (≥ 18 ans) bénéficiant d'une chirurgie cardiaque ou vasculaire majeure. La quantité de sang économisée à l'aide de tubes de petit volume et en combinaison avec un dispositif de conservation du sang plutôt que des tubes de volume standard a été estimée pour la chimie sérique (sérum), les tubes d'acide éthylène-diamine-tétra-acétique (EDTA), les tubes de coagulation au citrate de sodium (CCS) et l'analyse des gaz du sang artériel (GSA). RéSULTATS: La perte sanguine totale moyenne due au prélèvement de phlébotomie à l'aide de tubes de volume standard pendant l'hospitalisation était de 167,9 mL (intervalle de confiance [IC] à 95 %, 158,0 à 177,8), 255,6 mL (IC 95 %, 226,5 à 284,6) et 695,3 mL (IC 95 %, 544,1 à 846,4) chez les patient·es bénéficiant d'une chirurgie cardiaque avec une durée de séjour à l'hôpital de 0 à 10, 11 à 20, et ≥ 21 jours, respectivement. La perte sanguine totale moyenne due à la phlébotomie pendant l'hospitalisation était de 80,5 mL (IC 95 %, 70,5 à 90,6), 225,0 mL (IC 95 %, 135,1 à 314,8 mL) et 470,3 mL (IC 95 %, 333,5 à 607,1) chez les patient·es ayant bénéficié d'une chirurgie vasculaire avec des durées de séjour de 0-10, 11-20 et ≥ 21 jours, respectivement. Les patient·es ayant séjourné au moins deux jours à l'USI ont eu une perte de sang moyenne de 146,6 mL (IC 95 %, 134,6 à 158,6 mL) et celles et ceux ayant séjourné ≥ 11 jours ont subi une perte de 1428 mL (IC 95 %, 1117,8 à 1739,2). L'utilisation d'un dispositif de prélèvement sanguin fermé et de tubes de petit volume (sérum, EDTA, SCC et gsa) a réduit la perte de sang de 82,8 mL pour les patient·es ayant séjourné à l'USI 2 jours et jusqu'à 824,0 mL pour les patient·es ayant séjourné en USI ≥ 11 jours. CONCLUSION: Les tests de laboratoire diagnostiques sont associés à une perte de sang importante chez les patient·es, mais constituent un facteur de risque modifiable. L'utilisation de tubes de petit volume et de dispositifs fermés de prélèvement sanguin diminue le volume de sang prélevé pour analyse et prévient le gaspillage de sang.

Anatomical variation of femoral vessels and ultrasound-guided femoral vein puncture for catheter ablation of arrhythmias.

OBJECTIVE: This study aims to investigate the anatomical variations in femoral vasculature and evaluate the clinical value of ultrasound-guided femoral vein puncture in catheter ablation procedures. METHODS: In this retrospective analysis conducted from January 2023 to March 2023, we examined data from patients who underwent catheter ablation with ultrasound-guided femoral venipuncture. We evaluated the anatomy of the femoral vasculature at both high and low inguinal levels. Based on the relationship between the femoral vein and artery, we classified the anatomy into four types: Type I (vein parallel to artery without overlap), Type II (vein medial to artery with lumen overlap ≤50%), Type III (vein posterior to artery with lumen overlap > 50%), and Type IV (vein lateral to artery). Additionally, we assessed procedure-related vascular complications that required interventions or prolonged hospital stays. RESULTS: A total of 254 patients were included in this study. At the upper inguinal level, most cases (92.5%) exhibited Type II, followed by Type I (6.5%), while Type III (0.6%) and IV (0.4%) were less common. At the lower inguinal level, Type II accounted for 70.7%, there was a significantly higher proportion of Type III (23.4%) and Type IV (5.9%). The overall complication rate was 0.4%, no pseudoaneurysm or hematoma was observed in our study. CONCLUSION: Our study revealed significant anatomical variations in the relationship between the femoral vein and femoral artery. Ultrasound-guided femoral venipuncture significantly reduced vascular complication rate, making it a valuable tool for guiding puncture procedures.

A Comparison of the Effects of Acupressure and Music on Venipuncture Pain Intensity in Children: A Randomized Controlled Clinical Trial.

Pain from injections is common in children of all ages, and more than 90% of hospitalized children experience invasive and painful procedures such as venipuncture. In light of the complications associated with pain relief medications, nonpharmacological and complementary medicine approaches have gained attention. This study aims to compare the effects of acupressure and music on venipuncture pain intensity in children. This randomized controlled clinical trial involved 180 children aged 3-6 years who sought treatment at the Children's Medical Center Hospital Emergency Department at Tehran University of Medical Sciences, Iran. The children were randomly assigned to one of three groups: acupressure, music, or control. The interventions were given within 5 minutes, starting 3 minutes before the venipuncture and continuing until completion. The interventions included playing music through headphones and applying acupressure to the Hugo point. Venipuncture was carried out under identical conditions using an Angiocath 24G needle. Pain intensity was assessed using the Oucher scale. Data were analyzed using SPSS 24, employing the Kruskal-Wallis, chi-square, and Bonferroni pairwise comparison tests, with a significance level of 0.05. The mean pain intensity was 3.32 ± 1.44 in the music group, 4.82 ± 1.51 in the acupressure group, and 8.32 ± 1.10 in the control group. Pain intensity significantly differed among the three groups (p < 0.001). Specifically, pain intensity was lower in the music group compared to both the acupressure (p < 0.001) and control (p < 0.001) groups. Furthermore, pain intensity was lower in the acupressure group than in the control group (p < 0.001). Based on the results, music and acupressure methods effectively reduce pain intensity during venipuncture in children. Considering that music demonstrated a more pronounced effect in alleviating venipuncture pain than acupressure, the recommendation is to utilize music as a method of pain management during venipuncture in children. Iranian Registry of Clinical Trials, Trial No. IRCT20120109008665N15, was registered on 6 December 2021.

Benefits to Clinicians of Nonpharmacological Distraction During Pediatric Medical Procedure.

CONTEXT: Nonpharmacologic distraction (NPD) during medical procedures in children is known to be beneficial to patients; however, no reviews have assessed their benefits to medical providers. OBJECTIVES: We aimed to assess the benefits of NPD to medical providers. DATA SOURCES: We searched 5 databases for relevant articles. STUDY SELECTION: Peer-reviewed published randomized controlled trials comparing NPD with standard care that included children who had undergone medical procedures were included. DATA EXTRACTION: Primary outcomes were procedure time, number of medical staff involved, and initial success rate of venipuncture. Two reviewers assessed the risk of bias by using the Cochrane Collaboration (Oxford, United Kingdom)'s Randomized Controlled Trials Risk of Bias Tool, and we performed a meta-analysis to assess efficacy. RESULTS: We included 22 trials with 1968 participants. The main NPD was audiovisual distraction, such as tablets. No significant difference was found in venipuncture procedure time (mean difference: -9.79; 95% confidence interval: -22.38 to 2.81; low certainty). We found no studies on the number of medical staff. CONCLUSIONS: Our review did not find any clear NPD-associated benefit for the medical provider. The review included a small amount of literature, analyzed a small number of cases, and had a low certainty of evidence regarding procedure duration; therefore, further studies are needed to conclude the benefits to clinicians of NPD.

Blood Samples from Midline Catheters: Clinically Equivalent to Venipuncture.

PowerGlide Pro™ Midline Catheters, manufactured by Becton Dickinson, are marketed as capable of obtaining blood specimens. However, there is insufficient research to validate the laboratory results collected from these specialty catheters. The purpose of this research study was to determine whether blood samples obtained via venipuncture and samples obtained directly from a midline catheter are clinically equivalent. A qualitative study was completed per recommendations published in Clinical and Laboratory Standards Institute (CLSI) standards EP-05-A3 to determine whether the 2 modalities are clinically equivalent. A 12-point correlation study was performed, comparing blood results from phlebotomy venipuncture and midline catheter blood draws for 20 successful participants. Results were compared with an EP Evaluator. Report interpretation was completed using the 2-instrument comparison module to determine whether the 2 methods were clinically equivalent. All correlated specimens resulted within the medically acceptable total allowable error, proving the 2 methods clinically equivalent. The study concluded that blood draws from midline catheters are clinically equivalent to venipuncture and are an acceptable form of specimen collection for laboratory studies.

Flebotomía (sangría) terapéutica en domicilio / Therapeutic phlebotomy (bloodletting) at home

Introducción: Paciente de sexo femenino de 86 años de edad, seguida en la unidad de hematología de nuestro hospital por una anemia normocitica-normocromica que tras tratamiento con darbopoetina alfa 40 mcg subcutánea semanal durante tres meses, es diagnostica-da de poliglobulia. Se solicitó flebotomía terapéutica de 400 cc de sangre. Tras su realización, se realiza control analítico resultando hemoglobina: 14.8mg/dl y hematocrito:42.2% (valores en rango). Desarrollo de la experiencia: El procedimiento se llevó a cabo en casa de la paciente sin necesidad de movilizarla de su cama, pues se encuentra encamada. Extraemos la cantidad de sangre indicada en la prescripción(400cc), sin ninguna complicación. Conclusiones: En este caso pudimos realizar un procedimiento de rango hospitalario en el domicilio de la paciente, liberando, por un lado, a los familiares de la “carga” del desplazamiento al hospital, y por otro, protegiendo la paciente de complicaciones relacionadas con la asistencia hospitalaria (infecciones nosocomiales, desorientación entre otras).Así mismo, con menos recursos, pudimos realizar una atención humanizada y segura, logrando el objetivo terapéutico.

She was treated with a Therapeutic phlebotomy of 400 cc of blood. The post treatment blood analysis showed values within range, Hemoglobin 14.8mg/dl and Hematocrit 42.2%. Development of Experience: The procedure was carried out in the patient’s house avoiding to move her from her own bed since she is a bedbridden patient. The ammount of blood prescribed, 400 cc, was drawn without any com-plications.Conclusions: This time, we have been able to develop a procedure that ussually we have to perform in the hospital in the patient best enviroment, her house. Avoiding both, the patient to be expose to the potential complication from an hospital enviroment ( infeccions, desorientation as many others) and the family to move the patient from her own bed. In summary, we reach the terapeuthic goal with an holistic and safe care attention but using less resources. (AU)

Comparing the effect of aromatherapy with breast milk, Lavandula stoechas, and Rosa damascena on venipuncture pain in preterm infants.

INTRODUCTION AND OBJECTIVES: Since preterm infants frequently undergo painful diagnostic and therapeutic procedures, pain management, especially through non-pharmacological methods, will be extremely beneficial. Accordingly, the present study aimed to compare the effects of aromatherapy with breast milk, Lavandula stoechas, and Rosa damascena on venipuncture pain in preterm infants. METHODS: In this interventional study, preterm infants were randomly divided into four groups of aromatherapy with breast milk (25 infants), Lavandula stoechas (25 infants), Rosa damascena (25 infants), and sham (25 infants). One minute before, during, and two minutes after venipuncture, the Neonatal Infant Pain Scale (NIPS) as well as heart rate and SPO2 were measured. RESULTS: The results indicated that pain intensity was significantly lower during and after venipuncture in all the aromatherapy methods compared with the sham group (P < 0.001). Breast milk odor decreased the pain more than the other two odors during and after venipuncture (P < 0.001); however, there was no significant difference between Lavandula stoechas and Rosa damascena (P = 0.94). SPO2 was significantly higher in infants in the Lavandula stoechas (P < 0.001) and Rosa damascena (P = 0.03) groups compared with the sham infants. CONCLUSION: All three aromatherapy methods were effective in decreasing preterm infants' venipuncture pain. Since no study on the effect of aromatherapy with Rosa damascena was found in this regard, the effectiveness of aromatherapy with Rosa damascena is of great importance, and future studies are recommended to analyze this topic in greater depth.
