Haemochromatosis.

Haemochromatosis is one of the most common genetic diseases affecting patients of northern European ancestry. It is overdiagnosed in patients without iron overload and is underdiagnosed in many patients. Early diagnosis by genetic testing and therapy by periodic phlebotomy can prevent the most serious complications, which include liver cirrhosis, liver cancer, and death. This Seminar includes an update on the origins of haemochromatosis; and an overview pathophysiology, genetics, natural history, signs and symptoms, differential diagnoses, treatment with phlebotomy, outcomes, and future directions.

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.

Adverse effects of therapeutic phlebotomies: Prospective study of 587 procedures.

BACKGROUND: Therapeutic phlebotomy (TP), a widely used medical procedure, can be performed on diverse patients with iron overload or polyglobulia. However, its adverse events are not well known as most of the information on phlebotomy is derived from healthy blood donors (0.1%-5.3%). In contrast, TP is applicable to a broader, more complex population with comorbidities and old age. To ascertain the incidence of adverse events in phlebotomies, we conducted a prospective study on patients who attended our Unit. STUDY DESIGN AND METHODS: We prospectively gathered data from patients referred to our Unit for TP. Data regarding demographics, health status, and adverse events within at least 24 h of phlebotomy were gathered via a structured questionnaire during each visit. RESULTS: Between August 2021 and September 2022, 189 patients underwent 587 procedures. Most patients were men, over 60 (57.3%) had comorbidities, and 93% underwent at least two procedures during the study period. Twenty patients (10.8%) presented 25 adverse events (4.3% of phlebotomies), usually vasovagal reactions, none of which were clinically relevant, and all were managed by nursing staff on site, with full patient recovery. DISCUSSION: The rate of adverse events (<5%) in patients undergoing TP was low and comparable to that seen in healthy blood donors. Consequently, even old patients and those with some comorbidities can safely undergo TP when the process is carefully managed.

Comparison of trace image colors for kids-book with two active distractions in reducing pain and fear of children during the venipuncture procedure.

This study investigated the effectiveness of trace image and coloring for kids-book (TICK-B), cough trick, and balloon inflation techniques in reducing pain and fear in children during venipuncture. The current study is a prospective, controlled, and randomized trial (RCT). School-aged children who required venipuncture were involved in the study. Pediatric patients were randomly assigned to four groups: the TICK-B group, the cough trick group, the inflation of balloons, and the control groups. Before and after the procedure, the children and their parents were interviewed. Wong-Baker (FACES) Pain Rating Scale was applied to measure the severity of pain. Children's Fear Scale was applied to measure children's fear. This study involved the 160 children (mean age, 8.39-2.18 years). The severity of pain and fear levels among the children during and after the procedure were significantly different (p = 0.001). Pain and fear were significantly decreased in children in the intervention groups compared with those in the control group (p < 0.05). In the TICK-B group, participants reported significantly less pain and fear during the venipuncture procedure than in the cough trick, balloon inflation, and control groups (P = 0.001, p = 0.001, p = 0.001) and after the procedure (p = 0.001, p = 0.002, p = 0.002). There was a similar significance found in the level of fear during the procedure (p = 0.001, p = 0.002, p = 0.006), and after the procedure (p = 0.001, p = 0.008, p = 0.015).    Conclusion: TICK-B was the most effective method for decreasing the pain and fear of children associated with venipuncture procedures. Furthermore, the distraction technique of coughing and inflating balloons also proved efficacious in decreasing the pain and fear of children during venipuncture.    Trial registration: The study has been registered with ClinicalTrials.org under the number NCT04983303. It was retrospectively registered on July 26, 2021. What is Known: • Venipuncture, one of the most painful and uncomfortable procedures for children, caused great fear and discomfort during the procedure. What is New: • The TICK-B technique, music listening, and cartoon watching techniques are effective, simple, and safe ways to reduce children's fear and pain. These interventions provide a good way for children and their parents to collaborate during painful medical procedures. • No studies have compared the impact of TICK-B during venipuncture.

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.

Exploring Relations Between Unique Patient Characteristics and Virtual Reality Immersion Level on Anxiety and Pain in Patients Undergoing Venipuncture: Secondary Analysis of a Randomized Control Trial.

BACKGROUND: Virtual reality (VR) is a well-researched digital intervention that has been used for managing acute pain and anxiety in pediatric patients undergoing various medical procedures. This study focuses on investigating the role of unique patient characteristics and VR immersion level on the effectiveness of VR for managing pediatric pain and anxiety during venipuncture. OBJECTIVE: The purpose of this study is to determine how specific patient characteristics and level of immersion during a VR intervention impact anxiety and pain levels for pediatric patients undergoing venipuncture procedures. METHODS: This study is a secondary data analysis of 2 combined, previously published randomized control trials on 252 pediatric patients aged 10-21 years observed at Children's Hospital Los Angeles from April 12, 2017, to July 24, 2019. One randomized clinical trial was conducted in 3 clinical environments examining peripheral intravenous catheter placement (radiology and an infusion center) and blood draw (phlebotomy). Conditional process analysis was used to conduct moderation and mediation analyses to assess the impact of immersion level during the VR intervention. RESULTS: Significant moderation was found between the level of immersion and anxiety sensitivity when predicting postprocedural anxiety (P=.01). Patients exhibiting the highest anxiety sensitivity within the standard of care yielded a 1.9 (95% CI 0.9-2.8; P<.001)-point elevation in postprocedural anxiety relative to individuals with high immersion levels. No other significant factors were found to mediate or moderate the effect of immersion on either postprocedural anxiety or pain. CONCLUSIONS: VR is most effective for patients with higher anxiety sensitivity who report feeling highly immersed. Age, location of the procedure, and gender of the patient were not found to significantly impact VR's success in managing levels of postprocedural pain or anxiety, suggesting that immersive VR may be a beneficial intervention for a broad pediatric population.

Efficacy of Buzzy Device Versus EMLA Cream for Reducing Pain During Needle-Related Procedures in Children: A Randomized Controlled Trial.

OBJECTIVES: Several pain management tools exist but with limitations in their efficacy or applicability. The EMLA (eutectic mixture of local anesthetics) cream is currently used for pain relief for needle-related procedures; however, it needs a minimum of 30 to 45 minutes to be effective. The Buzzy is a device that generates vibrations with cold leading to quicker pain relief. Our aim was to evaluate the effect of the Buzzy device in pain and anxiety reduction compared with EMLA cream in children requiring intravenous cannulation or venepuncture. METHODS: This was a randomized clinical trial comparing pain and anxiety reduction by Buzzy device with the standard care (EMLA cream) in children aged 2 to 14 years who required blood extraction or intravenous cannulation based on their clinical needs. Eligible patients were randomized to either Buzzy device as the intervention or EMLA cream as the control. The outcome measures were the degree of pain scores and anxiety ratings at different stages of the needle-related procedures. RESULTS: A total of 300 patients with a mean age of 6.5 ± 3.1 years were enrolled. Baseline characteristics were similar between the Buzzy device and EMLA cream groups. The observed pain scores by research nurses and a parent were significantly lower in the EMLA group compared with the Buzzy device group; however, the pain scores by the self-assessment scale were not statistically significant with mean difference of -0.332, 95% confidence interval, -0.635 to -0.028 ( P = 0.062). The level of anxiety was significantly lower in EMLA compared with Buzzy device ( P = 0. 0.0001). Both staff and parents' satisfaction, success rate of cannulation, type of blood tests, and comment on the physician on the results were similar in both groups. CONCLUSIONS: Pain and anxiety relief using the Buzzy device is not as effective as EMLA cream in children requiring venepuncture. However, rapid onset of action of the Buzzy device is valuable in decreasing waiting time in a busy emergency department. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT05354739.

Atraumatic care practice from the child and parent perspective: The case of a pediatric phlebotomy unit.

PURPOSE: This study aimed to determine the effect of the child's self-selected distraction methods used during the phlebotomy procedure on the feeling of fear and pain in children and parental satisfaction. METHODS: The study, planned as a randomized controlled trial, was conducted with 219 children aged 5-10 years and their parents in the pediatric phlebotomy unit between March and June 2023. Different distraction methods (foam balloon, stress ball, musical book) were applied to the children in the intervention group during the phlebotomy procedure. The data were analyzed with the SPSS 22.0 package program. RESULTS: There was a statistically significant difference between the scores of the children in the intervention and control groups on the Children's Fear Scale before the phlebotomy, and on the Wong-Baker Faces Pain Rating Scale after phlebotomy according to self- and parental assessment (p < 0.05). A statistically significant difference was found between the satisfaction levels of the parents after the procedure in the intervention and control groups with the health care service provided during the phlebotomy process (p < 0.05). CONCLUSION: Distraction methods, one of the atraumatic nursing interventions used before the phlebotomy procedure, were determined to be effective in reducing the child's fear and the pain experienced due to the procedure. The study also showed that the satisfaction of parents was positively affected by the atraumatic care provided to their children. PRACTICE IMPLICATIONS: The atraumatic care approach should be used to prevent anxiety and fear experienced by parents and children and to reduce the child's pain.

Effect of combining oral glucose solutions with supportive positions on pain during heel puncture blood sampling in premature infants: A randomized quadruple-blinded experimental study.

PURPOSE: The trial aimed to assess the impact on pain scores of the administration of oral glucose solutions at different concentrations and in combination with supportive positions during heel puncture procedures. DESIGN & METHODS: This trial was structured as a quadruple-blinded experimental study conducted at a single center - a Level II and IVa NICU between June 2022-2023. Included in the study were 128 premature infants born with a gestational age of between 33 and 36 weeks and a postnatal age of <7 days. For the heel puncture procedures, four distinct interventions were employed, each involving supportive positions and oral solutions. All interventions were recorded on video for analysis, and data were collected using the "Infant Information and Observation Form" and "Neonatal Pain, Agitation and Sedation Scale (N-PASS)". The N-PASS was rated by two independent nurses. The data were analyzed with the two-way repeated measures ANOVA and post-hoc Bonferroni tests. RESULTS: The descriptive and clinical characteristics were similar in all groups (p > 0.05). The pain scores, physiological variables and total crying times of the premature infants differed significantly depending on the interventional groups and times, and the interaction between the groups and times (p < 0.05). CONCLUSIONS: Combining glucose solutions with supportive positions led to a reduction in pain scores, a decrease in total crying time when compared to the use of supportive positions alone. PRACTICE IMPLICATIONS: Combining an oral 20% glucose solution with supportive positions can be recommended to reduce pain during unplanned heel puncture procedures in the absence of a parent in the unit.

Proposed dietary recommendations for iron overload: a guide for physician practice.

PURPOSE OF REVIEW: Iron overload disorders such as hemochromatosis involve unregulated absorption of dietary iron, leading to excessive iron accumulation in multiple organs. Phlebotomy is the standard of care for removal of excess iron, but dietary modification is not standardized in practice. The purpose of this article is to help standardize hemochromatosis diet counseling based on commonly asked patient questions. RECENT FINDINGS: The clinical benefit regarding dietary modification in iron overload patients is limited due to lack of large clinical trials, but preliminary results are promising. Recent studies suggest diet modification could reduce iron burden in hemochromatosis patients resulting in less annual phlebotomy as supported through small patient studies, concepts of physiology, and animal studies. SUMMARY: This article is a guide for physicians to counsel hemochromatosis patients based on commonly asked questions such as foods to avoid, foods to consume, use of alcohol, and use of supplements. The goal of this guide is to help standardize hemochromatosis diet counseling to reduce phlebotomy amount in patients. Standardization of diet counseling could help facilitate future patient studies to analyze the clinical significance.

Beyond fear: A longitudinal investigation of emotions and risk of a vasovagal reaction in first-time whole-blood donors.

BACKGROUND: Fear is a recognized predictor of vasovagal reactions (VVRs) in blood donors. However, less is known about the role of other emotions, including positive emotions, that donors might experience. The aim of this study was to identify the emotions experienced in center that predict onsite VVRs, and to determine at what point during the donation appointment, the experience of these emotions is most influential. STUDY DESIGN AND METHODS: A sample of 442 first-time whole-blood donors (57.7% female; mean ± SD age 30.7 ± 11.7 years) completed a survey in the waiting area and before venepuncture in the donation chair to assess their current emotional experience. The survey data were matched with routinely-collected demographic, donation, and donor adverse event information. A generalized estimating equations model was used to identify emotions associated with the occurrence of a VVR. RESULTS: A total of 56 (12.7%) participants experienced a VVR. The occurrence of a VVR was significantly associated with lower love/closeness/trust (OR: 0.53, 95%CI: 0.34-0.82) and higher scared/fearful/afraid (OR: 1.96, 95%CI: 1.18-3.25) states. Significant interaction effects suggested that the effect of scared/fearful/afraid decreased while stressed/nervous/overwhelmed increased from the waiting area to before venepuncture on the likelihood of a VVR. DISCUSSION: To effectively reduce donor VVR risk, blood collection agencies need to address a broader range of emotions at different points during the donation process.

Child Emotion Regulation Capacity Moderates the Association Between Parent Behaviors and Child Distress During Pediatric Venipuncture.

OBJECTIVES: Medical needle procedures are a common source of pain, distress, and fear for children, which can worsen over time and lead to needle noncompliance and avoidance, if unaddressed. Children's pain experience is multiply determined by external (e.g., parent behaviors) and internal (e.g., cognitive and affective) factors. Some parent behaviors (e.g., reassurance, giving control to child, empathy, apologies, criticism) have related to poor child pain experiences. No research has examined how children's internal emotion regulation, commonly measured via heart rate variability (HRV), may buffer, or strengthen this association. This study is the first to examine child HRV in relation to pain experiences, and as a moderator between a constellation of parent behaviors (reassurance, giving control, empathy) and child pain, fear, and distress. METHODS: Sixty-one children aged 7-12 years undergoing venipuncture and a parent participated. Child HRV was measured before the procedure. After venipuncture, children rated their pain and fear. Parent and child behaviors during venipuncture were coded using the "distress promoting" and "distress" composites of the Child-Adult Medical Procedure Interaction Scale-Revised. RESULTS: Children with lower HRV displayed greater distress. Child HRV moderated the positive association between parent behaviors (reassurance, giving control, empathy) and child distress such that the association was strongest among children with low HRV. CONCLUSIONS: Findings suggest children with lower HRV, indicative of lower emotion regulation capacity, may be at risk of experiencing higher levels of distress and may be more vulnerable to distress when facing parent reassurance, giving control, and empathy verbalizations during venipuncture.

Active production of music as distraction for venipuncture in children and adolescents: a randomized clinical trial.

More than 50% of children report considerable pain during venipuncture or intravenous cannulation. Despite the tools and techniques may be employed to reduce pain and distress in everyday clinical practice, the care offered is frequently insufficient. Music's potential effect in healthcare settings has received increasing attention. This study aimed to verify if the active production of music with a Leap Motion Controller could help decreasing pain and distress during venipuncture in children and adolescents. We conducted an open-label randomized controlled clinical trial with parallel arms. Children aged 8 to 17 were enrolled at the blood-drawing center of the Institute for Maternal and Child Health IRCCS Burlo Garofolo of Trieste, Italy. We hypothesized that in order to demonstrate an adequate improvement in the pain score in the intervention group, at least 200 children, 100 in each group, were needed, with alpha 5% and 1-beta 80%. Differences between the groups were evaluated with the nonparametric Mann-Whitney U-test. The subjects were randomly assigned either to the active production of music group or to the standard of care group. The primary outcome was the median self-reported procedural pain score between experimental and standard of care group. Secondary outcomes were: the median pain and distress scores according to parental judgment and operators' judgment between the experimental and control group. Three hundred subjects entered the study and were randomized, 150 in the active production of music group and 150 in the standard of care group. Median self-reported pain scores were 1 (0-2) in the active production of music group and 2 (1-2) in the standard of care group and this difference was statistically significant (p = 0.0016). Median procedural distress was 1 (0-3) in the active production of music group and 3 (1-6) in the standard of care group, according to parental judgment, and this difference was statistically significant (p = 0.0000016). CONCLUSION: This research showed that the active production of music is a valuable distraction technique to decrease venipuncture related pain and distress in children and adolescents. TRIAL REGISTRATION: The study protocol was registered with ClinicalTrial.gov (June 28[th] 2022, NCT05441241) before the start of the subjects' enrolment. WHAT IS KNOWN: • The benefits of music on pain and anxiety are well known and have been tested during different painful procedures. • The effect of active production of music has never been tested in children during venipuncture. WHAT IS NEW: • In our study median self-reported pain scores and median procedural distress, according to parental judgment, were lower in the active production of music group than in the standard of care group and these differences were statistically significant.

Therapeutic communication improves patient comfort during venipuncture in children: a single-blinded intervention study.

The aim of this study was to examine whether therapeutic communication improves children's comfort during venipuncture compared to standard communication. This study was registered in the Dutch trial register (NL8221), December 10, 2019. This single-blinded interventional study was carried out in an outpatient clinic of a tertiary hospital. Inclusion criteria were age between 5 and 18 years, use of topical anesthesia (EMLA) and sufficient understanding of the Dutch language. 105 children were included, 51 assigned to the standard communication group (SC group) and 54 patients to the therapeutic communication group (TC group). The primary outcome measure was self-reported pain based on the Faces Pain Scale Revised (FPS-R). Secondary outcome measures were observed pain (numeric rating scale (NRS)), self-reported/observed anxiety in child and parent (NRS), self-reported satisfaction in child, parent and medical personnel (NRS), and procedural time. No difference was found for self-reported pain. Self-reported and observed anxiety (by parents and medical personnel) was lower in the TC group (p-values ranged from p = 0.005 to p = 0.048). Procedural time was lower in the TC group (p = 0.011). Satisfaction level of medical personnel was higher in the TC group (p = 0.014).   Conclusion: TC during venipuncture did not result in lower self-reported pain. However, secondary outcomes (observed pain, anxiety and procedural time) were significantly improved in the TC group. What is Known: • Medical procedures, especially needle related procedures, cause anxiety and fear in children and adults. • In adults communication techniques based on hypnosis are effective in reducing pain and anxiety during medical procedures. What is New: • Our study found that with a small change in communication technique (called therapeutic communication or TC), the comfort of children during venipuncture improves. • This improved comfort was mainly reflected by reduced anxiety scores and shorter procedural time. This makes TC suitable for the outpatient setting.

Impact of Phlebotomy Volume Knowledge on Provider Laboratory Ordering and Transfusion Practices in the Pediatric Cardiac ICU.

OBJECTIVES: Phlebotomy can account for significant blood loss in post-surgical pediatric cardiac patients. We investigated the effectiveness of a phlebotomy volume display in the electronic medical record (EMR) to decrease laboratory sampling and blood transfusions. Cost analysis was performed. DESIGN: This is a prospective interrupted time series quality improvement study. Cross-sectional surveys were administered to medical personnel pre- and post-intervention. SETTING: The study was conducted in a 19-bed cardiac ICU (CICU) at a Children's hospital. PATIENTS: One hundred nine post-surgical pediatric cardiac patients weighing 10 kg or less with an ICU stay of 30 days or less were included. INTERVENTIONS: We implemented a phlebotomy volume display in the intake and output section of the EMR along with a calculated maximal phlebotomy volume display based on 3% of patient total blood volume as a reference. MEASUREMENTS AND MAIN RESULTS: Providers poorly estimated phlebotomy volume regardless of role, practice setting, or years in practice. Only 12% of providers reported the availability of laboratory sampling volume. After implementation of the phlebotomy display, there was a reduction in mean laboratories drawn per patient per day from 9.5 to 2.5 ( p = 0.005) and single electrolytes draw per patient over the CICU stay from 6.1 to 1.6 ( p = 0.016). After implementation of the reference display, mean phlebotomy volume per patient over the CICU stay decreased from 30.9 to 14.4 mL ( p = 0.038). Blood transfusion volume did not decrease. CICU length of stay, intubation time, number of reintubations, and infections rates did not increase. Nearly all CICU personnel supported the use of the display. The financial cost of laboratory studies per patient has a downward trend and decreased for hemoglobin studies and electrolytes per patient after the intervention. CONCLUSIONS: Providers may not readily have access to phlebotomy volume requirements for laboratories, and most estimate phlebotomy volumes inaccurately. A well-designed phlebotomy display in the EMR can reduce laboratory sampling and associated costs in the pediatric CICU without an increase in adverse patient outcomes.

Clinical Effect of Modified Ultrasound-Guided Subclavian Vein Puncture.

Objective: This study compared the effect of ultrasound-guided subclavian vein puncture with traditional blind puncture and the double-screen control method by evaluating the one-time puncture success and total success rates, the completion time for puncture and catheterization, and short-term complications. Methods: From January 2020 to January 2021, 72 patients with right subclavian venipuncture catheterization were collected, 12 of whom were excluded (including 3 cases of pneumothorax, 2 cases of hemothorax, 1 case of difficult positioning of thoracic deformity, 1 case of severe drug eruption, 3 cases of clavicle fracture, and 1 case of severe coagulation dysfunction). The remaining 60 cases were randomly divided into the traditional group (n = 30) and the improved group (n = 30). We record two sets of ultrasound localization time, puncture time, one-time puncture power, total puncture success rate, and short-term (24-hour) complications. Results: Compared with the traditional group, the ultrasound positioning time and puncture time in the improved group were significantly reduced and the puncture success rate was higher. There were no complications, such as incorrect arterial puncture and the occurrence of pneumothorax, in either group. Conclusion: The improved ultrasound-guided subclavian vein catheterization technique can greatly reduce the catheterization time and improve the success rate of puncture and catheterization. It can also reduce the occurrence of complications and damage to adjacent tissues. The operation is simple, fast, and easy to master, and it has a high popularization clinical value.

Small-volume tubes to reduce anemia and transfusion (STRATUS): a pilot study.

PURPOSE: Blood sampling for diagnostic testing causes blood loss. Small-volume tubes have the same cost, dimensions, and blood-draw techniques as standard-volume tubes, and are compatible with laboratory equipment; however, they are not commonly used. We sought to assess the feasibility of a stepped-wedge cluster trial to determine whether small-volume tubes reduce transfusion compared with standard-volume tubes in intensive care unit (ICU) patients. METHODS: We conducted a prospective mixed-methods pilot study (before-after design) in one ICU with a six-week control period (standard-volume tubes) and a six-week intervention period (small-volume tubes). All patients admitted to the ICU were included. Feasibility was assessed as successful switch to small-volume tubes; adherence to tube size; sufficient volume for testing; user acceptance; barriers and facilitators to implementation; and 95% transfusion collection. We explored end-user acceptability using focus groups. RESULTS: One hundred and sixty-five patients were included in the standard-volume and 204 in the small-volume periods. Transition to small-volume tubes was successful. Random audits showed 100% compliance. The proportion of samples with inadequate volume for testing was the same for both groups (both, 0.2%). Based on ten focus groups, small-volume tubes were acceptable with no barriers identified. Transfusion data collection was 100%. Median [interquartile range] estimated blood loss due to laboratory testing per patient per day in ICU was 11 [8-17] mL with standard-volume and 6 [4-8] mL with small-volume tubes. CONCLUSION: Small-volume tubes can be implemented with acceptability to end-users and without barriers. They did not result in an increased frequency of inadequate samples. These results inform a trial to determine whether small-volume tubes reduce transfusion. STUDY REGISTRATION: ClinicalTrials.gov (NCT03284944); registered 15 September 2017.

RéSUMé: OBJECTIF: Les prélèvements sanguins pour les tests diagnostiques provoquent des pertes de sang. Les tubes de prélèvement de petit volume entraînent le même coût, ont les mêmes dimensions et nécessitent les mêmes techniques de prélèvement sanguin que les tubes de volume standard, en plus d'être compatibles avec l'équipement de laboratoire; cependant, ils ne sont pas couramment utilisés. Nous avons cherché à évaluer la faisabilité d'un essai clinique à intervention échelonnée visant à déterminer si les tubes de petit volume réduisaient la transfusion par rapport aux tubes de volume standard chez les patient·es de l'unité de soins intensifs (USI). MéTHODE: Nous avons mené une étude pilote prospective à méthodes mixtes (conception avant-après) dans une unité de soins intensifs, avec une période de contrôle de six semaines (tubes de volume standard) et une période d'intervention de six semaines (tubes de petit volume). Tou·tes les patient·es admis·es à l'USI ont été inclus·es. La faisabilité a été évaluée comme étant la transition réussie vers des tubes de petit volume; le respect de la taille du tube; un volume suffisant pour les tests sanguins; l'acceptation de l'utilisateur·trice; les obstacles et les facilitateurs à la mise en œuvre; et une collecte de données de transfusion de 95 %. Nous avons exploré l'acceptabilité par l'utilisateur·trice final·e à l'aide de groupes de discussion. RéSULTATS: Cent soixante-cinq patient·es ont été inclus·es dans le groupe volume standard et 204 dans les groupes pour la période de petit volume. La transition vers des tubes de petit volume a été couronnée de succès. Les audits aléatoires ont montré une observance de 100 %. La proportion d'échantillons dont le volume était insuffisant pour l'analyse était la même dans les deux groupes (0,2 % dans les deux cas). D'après dix groupes de discussion, les tubes de faible volume étaient acceptables et aucun obstacle n'a été identifié. La collecte de données transfusionnelles était de 100 %. Les pertes de sang médianes estimées [écart interquartile] dues aux tests de laboratoire par patient·e et par jour à l'USI étaient de 11 [8 à 17] mL avec un volume standard et de 6 [4 à 8] mL avec des tubes de petit volume. CONCLUSION: Les tubes de petit volume peuvent être mis en œuvre en étant acceptés par les utilisateur·trices et sans obstacles. Ils n'ont pas entraîné une augmentation de la fréquence des échantillons inadéquats. Ces résultats procurent des informations pour une étude visant à déterminer si les tubes de petit volume réduisent la transfusion.

Pharmacological and non-pharmacological interventions in management of peripheral venipuncture-related pain: a randomized clinical trial.

BACKGROUND: Venipuncture is a routine nursing procedure in the pediatric ward for blood collection and transfusion. However, this procedure can cause severe pain and distress if not adequately managed. METHODS: Children aged 3-16 years old were randomized into three groups: EMLA group, distraction group, and combined group. The primary outcome was children's self-reported pain scored using the Wong-Baker FACES® Pain Rating Scale. The parents-reported and observer-reported pain were scored using the Revised Face, Legs, Activity, Cry and Consolability Scale, and children's salivary cortisol levels, heart rate, percutaneous oxygen saturation, venipuncture duration and retaining time of IV cannulas were the secondary outcomes. RESULTS: A total of 299 children (167 male, 55.8%, median age 8.5) were enrolled: EMLA group (n = 103), distraction group(n = 96) and combined group(n = 100). There was no statistical difference in self-reported pain (P = 0.051), parent-reported pain (P = 0.072), and observer-reported pain (P = 0.906) among the three groups. All three interventions can decrease children's pain during IV cannulations. Additionally, the distraction group's salivary cortisol levels were lower than the combined group(P = 0.013). Furthermore, no significant difference was observed in the heart rate(P = 0.844), percutaneous oxygen saturation (P = 0.438), venipuncture duration (p = 0.440) and retaining time of IV cannulas (p = 0.843) among the three groups. CONCLUSIONS: All three groups responded with slight pain during the peripheral venipuncture procedure. Therefore, medical workers in pediatric settings can use the interventions appropriate for their medical resources and availability while involving parents and children's preferences whenever possible.

Effect of eye shield and ear muffs on pain intensity during venous blood sampling in premature infants: a clinical trial study.

BACKGROUND: Today, due to the side effects of drugs, there is a greater desire to use non-pharmacological interventions to relieve pain caused by painful procedures. Using non-pharmacological interventions in combination is more effective than using them alone in relieving the pain of infants. Reducing sensory and environmental stimuli such as visual and auditory stimuli is one of the non-pharmacological methods to relieve pain. The aim of this study was to investigate the effect of using eye shield and ear muffs on pain intensity during venous blood sampling of premature infants. METHODS: In this clinical trial study, 148 premature neonates admitted to the Neonatal Intensive Care Unit of Rouhani and Children Hospitals in Babol were randomly assigned to four groups of 37. Fifteen minutes before intravenous blood sampling until 15 min later, in the first group, eye shield; in the second group, ear muffs, and in the third group, eye shield plus ear muffs were used. In the fourth group (control), blood sampling was performed routinely. NIPS pain scale and demographic questionnaire were used to collect the data. RESULTS: The results showed that during the venous blood sampling was a significant difference between the mean pain intensity of neonatal in the eye shield plus ear muffs group (3.14 ± 0.71), the ear muffs group (4.43 ± 1.21), the eye shield group (5.41 ± 1.04).) and the control group (5.94 ± 0.84) (P = 0.001). Moreover, after the venous blood sampling, there was a significant difference between the mean neonatal pain intensity in the eye shield plus ear muffs group (1.19 ± 0.39), the ear muffs group (1.43 ± 0.50), the eye shield group (1.33 ± 0.37) and the control group (1.89 ± 0.90) (P = 0.001). CONCLUSIONS: In this study, the pain severity during and after venous blood sampling in the ear muffs plus eye shield was lower than in other groups. Therefore, a combination of ear muffs and eye shield is recommended as a better pain reliever when performing venous blood sampling in premature infants.

The Effect of Distraction Methods During Venous Blood Sampling on Pain Levels in School-Age Children: A Systematic Review.

OBJECTIVES: This systematic review was conducted to examine the available evidence on the effects of distraction methods during venous blood sampling on pain levels in school-age children. DESIGN: A systematic review. DATA SOURCES: Pubmed, Web of Science, Scopus, Science Direct were searched using search terms. REVIEW/ANALYSIS METHODS: A systematic review of all relevant articles published between June 2017 and June 2022, was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: The applied search strategy identified 612 articles in four databases. A total of 2,032 school-age children in the 15 studies who met the study inclusion criteria were included in the review. Four studies used active distraction, eight studies used passive distraction, and three studies used both distraction methods. CONCLUSIONS: Active and passive distractions are efficacious interventions during venous blood sampling in reducing pain in school-age children. However, more studies are needed to determine the superiority between these two methods.
