The Effect of Acupressure on Acute Pain During Venipuncture in Children: Implications for Evidence-Based Practice.

AIMS: The study was conducted as a randomized controlled trial in order to determine the effects of acupressure on acute pain during venipuncture in children. METHODS: The population of the study consisted of children, aged between 9 and 12 years, who received venipuncture between September 2015 and June 2016 at a university hospital in Istanbul. The sample consisted of a total of 90 children, including 45 children in the acupressure group and 45 children in the control group, who met the sample inclusion criteria. The results of the study were obtained by using an information form, the State Anxiety Inventory for Children (STAIC), the visual analog scale (VAS), and the Faces Pain Scale-Revised (FPS-R). Acupressure was applied to the children in the acupressure group for 10 min before the venipuncture procedure. Pain, heart rate, and oxygen saturation levels of the children in the acupressure and control groups were evaluated both before and after the venipuncture procedure. RESULTS: The children in the acupressure and control groups were found to be similar in terms of age, gender, parents' educational levels and working status, number of venipuncture procedures, and mean anxiety scores. In the evaluation that was conducted before the venipuncture procedure, no statistically significant differences were observed between the heat rates, oxygen saturation levels, and expected pain scores from the venipuncture procedure in the children in the acupressure and control groups. On the other hand, it was observed that the children in the acupressure group (VAS: 19.51 ± 4.98; FPS-R: 2.08 ± 0.41) experienced less pain than the children in the control group (VAS: 47.37 ± 9.89; FPS-R: 4.84 ± 1.08), and there was a significant difference between the two groups (p< .000). LINKING EVIDENCE TO ACTION: Acupressure administration is effective in reducing the pain that is experienced by children during a venipuncture procedure.

Reduced risk of vasovagal reactions in Australian whole blood donors after national implementation of applied muscle tension and water loading.

BACKGROUND: A new national donor safety initiative was introduced in Australia in 2018, which aimed to encourage all whole blood donors to water load and to use applied muscle tension. This study evaluated the effect of this initiative on the rate of vasovagal reactions (VVR). STUDY DESIGN AND METHODS: Routinely collected data were used to identify whole blood donations and any associated VVRs before (n = 167,056 donations) and after implementation (n = 215,572 donations). Multivariate logistic regression analyses were performed to evaluate the differences in VVR rates. RESULTS: The total rate of VVRs declined from 22.5 per 1000 donations to 20.6 per 1000 donations after implementation, a reduction of 8% (p < 0.001). The rate of presyncopal reactions decreased by 8% in new donors and 12% in repeat donors. No impact was observed on the rate of syncope in any of the groups. The multivariate logistic regression analysis demonstrated the odds of experiencing a presyncopal reaction was reduced by 13% following implementation, with no significant effects on syncope. CONCLUSION: The findings of this study support the use of water loading and applied muscle tension in routine whole blood collection to reduce the incidence of VVRs.

The venodilation effects of tapping versus massaging for venipuncture.

AIM: To compare the effectiveness of tapping and massaging venodilation techniques by evaluating venous cross-sectional area, venous depth, venous palpation score, and questionnaire responses of study participants. METHODS: This study had a quasi-experimental design. Between August 2016 and October 2016, healthy adult volunteers (n = 30, mean ± standard deviation of age: 22.3 ± 2.2 years) were enrolled in this study. Three venodilation techniques were evaluated: the application of a tourniquet (Control Group), the application of a tourniquet and tapping of the participant's forearm (Tapping Group), and the application of a tourniquet and massaging of the participant's forearm (Massage Group). RESULTS: In all three groups, venous cross-sectional areas increased significantly after the application of the venodilation technique. The change ratio of venous cross-sectional area was significantly larger in the Massage Group than in the Control Group. Additionally, 83.3% of the participants selected massaging as their preferred venodilation technique, stating the technique was comfortable and provided a feeling of relief. CONCLUSIONS: No significant differences were observed between the degrees of venodilation that were achieved using the three investigated venodilation techniques. Nonetheless, massaging was deemed the most effective technique after considering the participants' subjective comments.

Haemochromatosis.

Haemochromatosis is defined as systemic iron overload of genetic origin, caused by a reduction in the concentration of the iron regulatory hormone hepcidin, or a reduction in hepcidin-ferroportin binding. Hepcidin regulates the activity of ferroportin, which is the only identified cellular iron exporter. The most common form of haemochromatosis is due to homozygous mutations (specifically, the C282Y mutation) in HFE, which encodes hereditary haemochromatosis protein. Non-HFE forms of haemochromatosis due to mutations in HAMP, HJV or TFR2 are much rarer. Mutations in SLC40A1 (also known as FPN1; encoding ferroportin) that prevent hepcidin-ferroportin binding also cause haemochromatosis. Cellular iron excess in HFE and non-HFE forms of haemochromatosis is caused by increased concentrations of plasma iron, which can lead to the accumulation of iron in parenchymal cells, particularly hepatocytes, pancreatic cells and cardiomyocytes. Diagnosis is noninvasive and includes clinical examination, assessment of plasma iron parameters, imaging and genetic testing. The mainstay therapy is phlebotomy, although iron chelation can be used in some patients. Hepcidin supplementation might be an innovative future approach.

Therapeutic recommendations in HFE hemochromatosis for p.Cys282Tyr (C282Y/C282Y) homozygous genotype.

Although guidelines are available for hereditary hemochromatosis, a high percentage of the recommendations within them are not shared between the different guidelines. Our main aim is to provide an objective, simple, brief, and practical set of recommendations about therapeutic aspects of HFE hemochromatosis for p.Cys282Tyr (C282Y/C282Y) homozygous genotype, based on the published scientific studies and guidelines, in a form that is reasonably comprehensible to patients and people without medical training. This final version was approved at the Hemochromatosis International meeting on 12th May 2017 in Los Angeles.

Exploring Holistic Comfort in Children Who Experience a Clinical Venipuncture Procedure.

PURPOSE: Children often experience the uncomfortable effects of invasive procedures as a part of primary care and during times of illness. Holistic comfort has been well documented in adult literature but little research exists on the understanding of holistic procedural comfort from the child's perspective. In this study, holistic comfort related to an invasive venipuncture procedure was explored in children age 5 to 7 years and their caregivers of all ages. DESIGN: A qualitative descriptive design described by Sandelowski was used. METHOD: The philosophical underpinnings of naturalistic inquiry of Guba and Lincoln were used. Semistructured interviews were conducted with 13 child and 15 caregiver participants. Children also drew pictures to help describe their perceptions. FINDINGS: Traditional thematic content analysis described by Hsieh and Shannon yielded four overarching themes of holistic comfort related to venipuncture procedures in children: Body Comfort, Cognitive and Emotional Comfort, Comfort in the Procedure Surroundings, and Comfort Play. CONCLUSIONS: Numerous recommendations for future research are included. Implications for nursing and related health sciences, organizational and administrative policy, invasive procedures, theory, and methods were found and are discussed. Findings from this study will assist nurses in providing procedure management for children from a holistic care perspective.

Comparison of Effects of Local Anesthesia and Two-Point Acupressure on the Severity of Venipuncture Pain Among Hospitalized 6-12-Year-Old Children.

The aim of the present study was to compare the effects of topical anesthesia and acupressure at the Yintang (Extra 1) and the Laogong (P-8) points on the severity of venipuncture pain among hospitalized 6-12-year-old children. A sample (n = 120) of 6-12-year-old hospitalized children was recruited from two teaching hospitals located in Rafsanjan, Iran. The children were allocated to the topical anesthesia, acupressure, and control groups. For children in the topical anesthesia and the acupressure groups, eutectic mixture of local anesthetic (EMLA) cream and two-point acupressure were used, respectively, prior to performing venipuncture, whereas children in the control group only received routine prevenipuncture care. The severity of venipuncture pain was evaluated 5 minutes after performing venipuncture by using the Face, Leg, Activity, Cry, and Consolability behavioral pain assessment scale. The findings revealed that pain severity in both experimental groups was significantly lower than that in the control group, whereas there was no significant difference between the experimental groups regarding pain severity. Although acupressure was as effective as topical anesthesia cream in alleviating children's venipuncture pain, nurses are recommending to use acupressure instead of pharmacological pain management agents because of its greater safety, cost-effectiveness, and applicability.

Improvement of chronic hepatitis B by iron chelation therapy in a patient with iron overload: A case report.

RATIONALE: This report describes seroconversion of hepatitis B surface antigen (HBsAg) in a patient with marked iron overload caused by chronic hepatitis B (CHB) after receiving iron chelation therapy and discusses the role of iron chelation therapy in CHB. PATIENT CONCERNS: Increased serum ferritin level for 2 months. DIAGNOSIS: Secondary iron overload and CHB. INTERVENTION: To relieve iron load of the body, the patient underwent regular phlebotomy therapy and deferoxamine (DFO) therapy. During the therapy, serum ferritin and hepatitis B virus (HBV) were monitored and the iron concentration of the liver and heart were followed by T2* of magnetic resonance imaging (MRI) scan. OUTCOMES: Serum ferritin gradually decreased. Approximately 1 year after the therapy, HBsAg turned persistently negative. LESSONS: Iron chelation therapy may attenuate HBV infection.

Transcutaneous Bilirubinometry in Jaundiced Neonates: A Randomized Controlled Trial.

BACKGROUND: For evaluation of jaundiced neonates, serum bilirubin (SB) or transcutaneous bilirubinometry (TcB) is used. Few data are available on the quantitative reduction of blood sampling by using TcB. METHODS: We conducted a randomized controlled trial in hospitalized jaundiced neonates ≥32 weeks' gestational age. In the intervention group, TcB was used and in the control group the decision to obtain a blood sample for SB was based on visual and clinical assessment. Outcome measure was the number of blood samples before phototherapy. When TcB was <50 µmol/L below the threshold for phototherapy, SB was obtained. The decision to start treatment was always based on an SB value. RESULTS: A total of 430 were randomized and included in the intention-to-treat analysis: 213 in the TcB group and 217 in the control group. In the TcB group, 104 (48.4%) had at least 1 blood sample taken for SB, versus 172 (79.3%) in the control group (difference 30.5%, 95% confidence interval 21.5-38.7, P < .001). The number of blood draws was significantly reduced by 38.5% (0.9 ± 1.1 vs 1.3 ± 1.0, difference -0.5, 95% confidence interval -0.7 to -0.3, P < .001). Peak of bilirubin value, indications for phototherapy, or exchange transfusion and hospitalization length were not different between groups. CONCLUSIONS: The use of TcB in jaundiced neonates is feasible and safe, resulting in a reduction of more than one-third in blood draws.

[Treatment by bloodletting in the past and present].

INTRODUCTION: Therapeutic bloodletting has been practiced at least 3000 years as one of the most frequent methods of treatment in general, whose value was not questioned until the 19th century, when it was gradually abandoned in Western medicine, while it is still practiced in Arabic and traditional Chinese medicine. CONTENT: In modern medicine bloodletting is practiced for very few indications. Its concept was modeled on the process of menstrual bleeding, for which it was believed to"purge women of bad humours. "Thus, bloodletting was based more on the belief that it helps in the reestablishment of proper balance of body "humours" than on the opinion that it serves to remove excessive amount of blood as well as to remove toxic "pneumas" that accumulate in human body. It was indicated for almost all known diseases, even in the presence of severe anemia. Bloodletting was carried out by scarification with cupping, by phlebotomies (venesections), rarely by arteriotomies, using specific instruments called lancets, as well as leeches. In different periods of history bloodletting was practiced by priests, doctors, barbers, and even by amateurs. In most cases, between one half of liter and two liters of blood used to be removed. Bloodletting was harmful to vast majority of patients and in some of them it is believed that it was either fatal or that it strongly contributed to such outcome. In the 20th century in the "Western"medicine bloodletting was still practiced in the treatment of hypertension and in severe cardiac insufficiency and pulmonary edema, but these indications were later abandoned. CONCLUSION: Bloodletting is still indicated for a few indications such as polycythemia, haemochromatosis, and porphyria cutanea tarda, while leeches are still used in plastic surgery, replantation and other reconstructive surgery, and very rarely for other specific indications.

Iron is prioritized to red blood cells over the brain in phlebotomized anemic newborn lambs.

BACKGROUND: Critically ill preterm and term neonates are at high risk for negative iron balance due to phlebotomy that occurs with frequent laboratory monitoring, and the high iron demand of rapid growth. Understanding the prioritization of iron between red blood cells (RBCs) and brain is important given iron's role in neurodevelopment. METHODS: Ten neonatal twin lamb pairs (n = 20) underwent regular phlebotomy for 11 d. Lambs were randomized to receive no iron or i.v. daily iron supplementation from 1 to 5 mg/kg. Serum hemoglobin concentration and reticulocyte count were assayed, iron balance calculated, and iron content of RBCs, liver, brain, muscle, and heart measured at autopsy. RESULTS: Among phlebotomized lambs: (i) liver iron concentration was directly related to net iron balance (r = 0.87; P < 0.001) and (ii) brain iron concentration was reduced as a function of net iron balance (r = 0.63) only after liver iron was depleted. In animals with negative iron balance, total RBC iron was maintained while brain iron concentration decreased as a percentage of the iron present in RBCs (r = -0.70; P < 0.01) and as a function of reticulocyte count (r = -0.63; P < 0.05). CONCLUSION: Phlebotomy-induced negative iron balance limits iron availability to the developing brain.

Medical Clowns and Cortisol levels in Children Undergoing Venipuncture in the Emergency Department: A Pilot Study.

BACKGROUND: Medical clowns are increasingly used for diminishing pain and anxiety during painful procedures being performed on children in the hospital setting. Cortisol levels rise as a response to emotional distress. OBJECTIVES: To investigate whether medical clown-assisted interventions to reduce child's distress during venipuncture have an effect on cortisol levels. METHODS: During a 1 year period, children requiring blood work or intravenous access in the pediatric emergency department were prospectively randomized to either the presence or absence of a medical clown during the procedure. The child's distress was evaluated using the Faces Pain Scale - revised (FPS-R) for the 4-7 year age group and the visual analog scales (VAS) for those aged 8-15 years. Serum cortisol levels were measured in blood samples obtained by venipuncture. RESULTS: Fifty-three children aged 2-15 years were randomly assigned to the study group (with medical clown, n=29) or to the control group (without medical clown, n=24). Combined pain scores of the study group and control group were 2.2 and 7.5 respectively (P < 0.001). No difference in mean cortisol levels was found between the study group and the control group at all ages (16.4 µg/dl vs. 18.3 µg/dl, P = 0.65). CONCLUSIONS: In this pilot study, medical clowns reduced the distress from venipuncture in children. No effect on cortisol levels was observed.

The effect of medical clowning on reducing pain, crying, and anxiety in children aged 2-10 years old undergoing venous blood drawing--a randomized controlled study.

UNLABELLED: Recently, the utilization of medical clowns to reduce anxiety, stress, and even pain associated with hospitalization has become popular. However, the scientific basis of this benefit and outcome is scant. Venipuncture and IV cannulation are very common sources of pain in ill children. To reduce pain, one common approach is to apply a local anesthetic prior to the procedure. In the current study, we sought to compare the utilization of medical clowning in this process with two control groups: (1) local anesthetic cream (EMLA®, Astrazeneca, London, UK) applied prior to the procedure (active control) and (2) the procedure performed with neither clown nor EMLA (control group). We hypothesized that a medical clown will reduce pain, crying, and anxiety in children undergoing this procedure.Children aged 2-10 years who required either venous blood sampling or intravenous cannulation were recruited and randomly assigned to one of the three groups. Outcome measures consisted of the duration of the whole procedure (measured objectively by an independent observer), the duration of crying (measured objectively by an independent observer), subjective assessment of pain level (a commonly used validated scale), and anxiety level regarding future blood exams (by questionnaire). Analysis of variance (ANOVA) was used to compare between the groups. p < 0.05 was considered statistically significant.One hundred children participated. Mean age was 5.3 ± 2.5 years (range 2-10 years). The duration of crying was significantly lower with clown than in the control group (1.3 ± 2.0 vs 3.8 ± 5.4 min, p = 0.01). With EMLA, this duration was 2.4 ± 2.9 min. The pain magnitude as assessed by the child was significantly lower with EMLA than in the control group (2.9 ± 3.3 vs 5.3 ± 3.8, p = 0.04), while with clown it was 4.1 ± 3.5, not significant when compared with the other two modalities. Hence, duration of crying was shortest with clown while pain assessment was lowest with EMLA. Furthermore, with clown duration of cry was significantly shorter than in controls, but pain perception did not significantly differ between these groups. As expected, the duration of the entire process was shortest in the control group (5.0 ± 3.8 min), moderate with clown (19.3 ± 5.8 min), and longest with EMLA (63.2 ± 11.4 min, p < 0.0001 between all). Parental reporting of a beneficial effect was greater with clown than with EMLA (3.6 ± 0.8 vs 3.0 ± 1.1, p = 0.02). Parental assessment of child's anxiety related to future blood tests as evaluated by telephone the following day revealed that it was significantly lower with clown than in the control group or EMLA (2.6 ± 1.2 vs 3.7 ± 1.3 or 3.8 ± 1.6, p < 0.01 for both). CONCLUSIONS: Distraction by a medical clown is helpful in children undergoing blood tests or line insertion. Although pain reduction was better with EMLA, both duration of cry and anxiety were lower with a medical clown. These results strongly encourage and support the utilization of medical clowns while drawing blood in children.

The Effect of Distraction on Pain Level Felt by School-age Children During Venipuncture Procedure--Randomized Controlled Trial.

The experimental study that follows was planned to determine the effectiveness of distraction on the pain level in school-age children as they underwent venipuncture. The study sample consisted of children between the ages of 7 and 12 years who underwent venipuncture at the Training and Research Hospital in Istanbul, Turkey between February and May 2012. A total of 144 children were conveniently sampled and evenly randomized into two groups of 72 children each. The primary instrument used to test children's pain level was the Faces Pain Scale-Revised (FPS-R). During the blood draw, the experimental group was given a kaleidoscope and told to look through it and describe what they saw, then rate their pain level on the FPS-R. Results showed that during venipuncture, the pain level of the control group was significantly higher (FPS-R = 3.27 ± 2.87) than the experimental group (FPS-R = 1.80 ± 1.84; p = .001) suggesting that distraction with a kaleidoscope is effective in reducing the pain children experience during venipuncture.

Tapping but not massage enhances vasodilation and improves venous palpation of cutaneous veins.

This paper investigated whether tapping on the median cubital vein or massaging the forearm was more effective in obtaining better venous palpation for venipuncture. Forty healthy volunteers in their twenties were subjected to tapping (10 times in 5 sec) or massage (10 strokes in 20 sec from the wrist to the cubital fossa) under tourniquet inflation on the upper arm. Venous palpation was assessed using the venous palpation score (0-6, with 0 being impalpable). Three venous factors-venous depth, cross-sectional area, and elevation-were also measured using ultrasonography. The venous palpation score increased significantly by tapping but not by massage. Moreover, all 3 venous measurements changed significantly by tapping, while only the depth decreased significantly by massage. The three venous measurements correlated significantly with the venous palpation score, indicating that they are useful objective indicators for evaluating vasodilation. We suggest that tapping is an effective vasodilation technique.

Can presence of a dog reduce pain and distress in children during venipuncture?

The aim of this study was to investigate the effectiveness of animal-assisted intervention as distraction for reducing children's pain and distress before, during, and after standard blood collection procedure. Fifty children (ages 4-11 years) undergoing venipuncture were randomly assigned to the experimental group (EG; n = 25) or to the control group (CG; n = 25). The blood collection procedure was carried on the children in the EG arm in the presence of a dog, whereas no dog was present when venipuncture was conducted on children in CG. In both cases, parents accompanied the child in the procedure room. Distress experienced by the child was measured with the Amended Observation Scale of Behavioral Distress, while perceived pain was measured with a visual analog scale or the Wong Baker Scale (Faces Scale); levels of cortisol in blood also were analyzed. Parental anxiety during the procedure was measured with State Trait Anxiety Inventory. Children assigned to the EG group reacted with less distress than children in the CG arm. Furthermore, cortisol levels were lower in the EG group compared with the CG group. There were no significant differences in pain ratings and in the level of parental anxiety. It appears that the presence of dogs during blood draw procedures reduces distress in children.

Relaxation and guided imagery used with 12-year-olds during venipuncture in a school-based screening study.

Needle-related procedures are reported to be problematic for children. In a school-based celiac disease screening, 12-year-olds' experiences with relaxation and guided imagery (R-GI) during venipuncture were investigated. One group tried nurse-led R-GI (n = 60) and another group received standard care (SC; n = 49). A mixed method design was applied using short written narratives, facial affective scale (FAS), and visual analog scale (VAS) for pain intensity. Qualitative content analysis highlighted that diversity and contradictions when facing blood tests. FAS scores were significantly lower in the SC group before (p = 0.01), during (p = 0.01), and after (p = 0.01) venipuncture. VAS scores did not differ between the groups. The blood test was mostly experienced as unproblematic, and GI during venipuncture did not decrease pain or affect. However, the fact that a number of children scored high FAS indicates a need for effective methods to help children cope with needle-related school-based procedures.

Partial manual exchange reduces iron accumulation during chronic red cell transfusions for sickle cell disease.

Iron overload is an inevitable consequence of chronic red cell transfusions without erythrocytapheresis or chelation therapy. The effectiveness of partial manual exchange, a technique used to slow iron loading, has not been evaluated. We evaluated all children with sickle cell disease (SCD) receiving chronic transfusion to identify chelation-naive subjects who had quantitative liver iron concentration (LIC) studies. Seventeen chelation-naive children with SCD received a median of 29 transfusions before first LIC determination. Serum ferritin concentrations were assessed before each transfusion. The mean volume of blood phlebotomized before each transfusion was 5.1±1.8 mL/kg, which cumulatively resulted in a calculated median of 35.0 mg/kg iron removal. Using linear regression, pretransfusion phlebotomy resulted in a statistically significant reduction in ferritin (-8.8 ng/mL of ferritin for each mg/kg of iron phlebotomized, P=0.02). A reduction in LIC from pretransfusion phlebotomy could not be established (P=0.4). Partial manual exchanges appear to be an effective strategy for slowing the pace of iron loading in the setting of chronic transfusion for SCD.
