The Use of ShotBlocker for Reducing the Pain and Anxiety Associated With Intramuscular Injection: A Randomized, Placebo Controlled Study

Effects of cold needle and ShotBlocker applied in the emergency department on pain and satisfaction in intramuscular injection pain: A randomized controlled trial

BACKGROUND

The most commonly reported side effect of intramuscular injection is pain. Cold needles and ShotBlocker can be used as non-pharmacological methods for pain relief. This study aims to determine the effect of cold needle and ShotBlocker on pain and satisfaction in intramuscular injection pain.

METHODS

This is a triple-blind, randomized controlled study. The study was conducted on 120 patients (40: control, 40: cold needle, 40: ShotBlocker) who presented to the emergency department of a university hospital in Turkey for cyanocobalamin injection in July-August 2024. Data were collected using a patient identification form, visual pain scale (VPS), and injection satisfaction scale. SPSS statistical package (version 22.0; SPSS, Inc., USA) was used to analyze the data.

RESULTS

In the study, the groups were found to be similar except for age and continuous drug use. The pain scores of the control group were significantly higher than those of the cold needle and ShotBlocker groups. Injection satisfaction was significantly higher in the cold needle and ShotBlocker groups than in the control group.

CONCLUSION

Both the Cold Needle and the ShotBlocker can be used as effective methods to reduce pain associated with intramuscular injections and improve injection satisfaction. Both methods are non-pharmacological, inexpensive, and easy to use, and they can be used safely and effectively in all clinical settings.

The Effect of Three Different Local Cold Applications on Pain Severity, Anxiety Level, and Physiological Parameters in Intra-Articular Injections for Knee Osteoarthritis Treatment

Minimizing pain and anxiety associated with intra-articular injection interventions is important for patient satisfaction and comfort. The sample of this quasi-experimental study consisted of 120 patients who received intra-articular knee injections for the first time. Patients were divided into four study groups before injection. The inter-group comparisons of the vital signs and mean pain and anxiety scores obtained immediately after the injection (0th minutes) and after 30 minutes indicated that mean systolic blood pressure, diastolic blood pressure, and pain scores were lower in the icepack application group, mean pulse rate score was lower in the cold spray group, and mean respiratory rate score was lower in the buzzy device group, with differences being statistically significant (p < .05). We conclude that icepack application is effective in reducing pain severity in intra-articular injections.

The effect of lavender oil use on pain and comfort level in intramuscular injection administration: A single blind randomized controlled study

CONTEXT

The fact that the concept of quality in health care services has come to the fore and that evidence-based practices have become widespread made such concepts as patient satisfaction and comfort important and priority parameters in determining the quality of health services.

OBJECTIVES

The aim of the study is to determine the effects of using lavender oil in intramuscular injection on injection pain, comfort level, blood pressure, pulse rate and respiratory rate.

METHODS

The study was designed as a prospective, single-blind randomized controlled trial. The research was conducted in accordance with the CONSORT Checklist guide. In our study, a total of 160 individuals were included in the sample, 80 of whom were control and 80 were intervention. Structured Information Form, Visual Analog Scale and Comfort Scale were used to collect the data of the research. Mann Whitney U, Kruskal Wallis test and Wilcoxon test were used to evaluate the data.

RESULTS

It was determined that the mean pain scores of the individuals who received intramuscular injection by applying lavender oil were statistically significantly lower than the individuals in the control group. Again, the comfort score averages of the individuals who were applied lavender oil were found to be statistically significantly higher than the control group. It was determined that the blood pressure, pulse rate and respiratory rate before the injection of the individuals in the control group increased statistically significantly according to the post-injection measurements, while the blood pressure, pulse rate and respiratory rate in the lavender oil group decreased significantly after the injection and remained within their normal values.

CONCLUSION

As a result, it was determined that the application of lavender oil in intramuscular injection had a positive and significant effect on the blood pressure, pulse rate and respiratory rate of the individuals on the injection pain and comfort level.

Effects of ShotBlocker® and the Helfer skin tap technique on pain and fear experienced during intramuscular injection among children aged 6-12 years in pediatric emergency units: A randomized controlled trial

BACKGROUND

In pediatric emergency units, intramuscular injection is one of the most common procedures that cause pain and fear in children. Reducing pain and fear is important for patient comfort.

OBJECTIVE

This randomized controlled experimental study aimed to determine the effects of ShotBlocker® and the Helfer skin tap technique on the pain and fear experienced by children aged 6-12 years during intramuscular injection in pediatric emergency units.

METHODS

This study was conducted from April 2022 to October 2023 among 177 children aged 6-12 years. ShotBlocker and the Helfer skin tap technique were applied during intramuscular injection among children in the intervention groups (ShotBlocker group: n = 59, Helfer skin tap technique group: n = 59), while children in the control group received routine injections. (n = 59). The levels of pain and fear were measured.

RESULTS

In the analysis of the age distribution of the children, the average age of the Helfer skin tap technique group was found to be 8.54 ± 2.00 years; ShotBlocker group, 8.46 ± 1.99 years; and control group, 9.19 ± 2.01 years. There was a significant difference in the post-intervention Wong-Baker Pain Scale and Child Fear Scale scores based on the evaluation of the children, parents, and observer nurses between the groups (p < 0.05). The pain and fear scores of the ShotBlocker group were lower than those of the control group (p < 0.05).

CONCLUSIONS

ShotBlocker is more effective in reducing pain than the Helfer skin tap technique among children receiving intramuscular injection. These cheap and easy-to-use methods are recommended for use in emergency units.

OBJECTIVE

to map scientific evidence regarding the use of local pressure devices in pain relief during injection procedures in patients.

METHODS

scoping review, following the recommendations of the JBI Manual for Evidence Synthesis and PRISMA-ScR, with searches conducted in the PubMed, EMBASE, CINAHL, LILACS, and PsycINFO databases, without temporal restrictions and with a cutoff date of March 2023.

RESULTS

a total of 1,514 studies were identified, with 20 articles included in the final sample. The ShotBlocker® device was utilized during subcutaneous and intramuscular injections in children and adults, proving beneficial in reducing pain, anxiety, and fear associated with the procedure.

FINAL CONSIDERATIONS

the ShotBlocker® is a low-cost, easy-to-use device that can enhance nursing clinical practice during painful procedures. However, studies involving the Brazilian Pikluc® device are scarce. Further research involving both local pressure devices is recommended.

Efficacy of ShotBlocker device versus vapocoolant spray for spinal needle pain relief during spinal anaesthesia in elective caesarean section - A randomised controlled trial

Background and Aims

Apprehension of pain due to a spinal needle is often a cause of anxiety and refusal. ShotBlocker provides non-painful physical stimulation, inhibiting pain perception. The vapocoolant spray contains ethyl chloride vapours, rapidly raising the skin temperature and hampering the transmission of noxious stimuli. The present study compared the effectiveness of the ShotBlocker device and the vapocoolant spray in reducing spinal needle-associated pain in primigravida women undergoing elective lower-segment caesarean section (LSCS).

Methods

We enroled 144 primigravida women undergoing elective LSCS and were randomised to Group SB (the ShotBlocker device was firmly pressed over the skin, and the spinal needle was inserted through its slit), Group V (the vapocoolant spray was applied at the puncture site before spinal needle insertion), and Group C (received local infiltration before spinal anaesthesia (SA)). The groups were compared for needle-associated pain and patient satisfaction using a 10-point visual analogue scale (VAS) and a 3-point Likert scale.

Results

The mean (standard deviation) [95% confidence interval (CI)] VAS scores of Group SB 3.85 (0.74) [3.64, 4.07] and Group V 3.04 (0.74) [2.83, 3.26] were significantly lower than that of Group C 5.19 (0.92) [3.28, 3.62]). On the Likert scale, the maximum number of patients in the vapocoolant group (64.6%) responded satisfactorily, while in the control group, the majority (62.5%) of participants responded dissatisfied (P < 0.001).

Conclusion

Both the ShotBlocker and vapocoolant spray reduce needle puncture-associated pain before SA in primigravida patients undergoing elective LSCS. However, the vapocoolant spray is more beneficial in reducing spinal needle-associated pain than the ShotBlocker device.

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

AIM AND OBJECTIVES

The purpose of this study is to see how ShotBlocker® affects the pain and comfort level associated with short peripheral intravenous cannula (PIV) insertion.

METHODS

The study was conducted on a single sample group using a pre-post design. Individuals in the sample group who underwent a brief PIV insertion procedure served as both the study's control and intervention groups. In the sample group, the same nurse inserted a peripheral intravenous catheter into the cephalic veins of the right and left forearms using a standard insertion and ShotBlocker®. The pain and comfort levels were assessed using the VAS and Comfort Scale.

RESULTS

When the distribution of the average pain and comfort scores of the individuals treated with the peripheral intravenous catheter was examined, it was found that the average pain score of the peripheral intravenous catheter insertion using ShotBlocker® was statistically significantly lower than the peripheral intravenous catheter insertion using the standard method, and the comfort score averages were statistically higher. When the correlation between the pain and comfort score averages of individuals undergoing peripheral intravenous catheter insertions was investigated, a statistically significant and strong negative relationship (p = 0.001) was discovered.

CONCLUSIONS

As a result, the use of ShotBlocker® during the short PIV insertion procedure is an effective method to reduce the pain caused by the peripheral intravenous catheter. It was determined that the comfort level of the individuals increased as the pain due to peripheral intravenous catheter insertion decreased.

Investigating 3D-printed disk compressing against skin for pain relief in intradermal infiltration anesthesia: a randomized controlled trial

BACKGROUND

Pain intensity may be varied during the needle advancing through different skin layers, injection into the intradermal layer may exclude mixed pain from deeper planes. This study aimed to investigate whether compressing a three-dimensional (3D)-printed disk against the skin may relieve pain associated with intradermal injection of local anesthetic which mimics the skin test procedure.

METHODS

After institutional review board approval, 3D-printed disks with projections were designed for this study. Enrolled patients were randomized to receive either a disk compressing against the axillary skin during the intradermal injection of local anesthesia (compressing disk group) or an intradermal injection of local anesthesia without any compression (no compressing disk group). The primary outcomes were pain intensity (100-mm visual analog scale) and satisfaction (5-point Likert scale) as assessed by patients.

RESULTS

Ninety patients with American Society of Anesthesiologists I-II physical status receiving intradermal local anesthesia prior to an ultrasound-guided axillary approach were included. Eighty-seven patients completed the study, with 44 and 43 patients in disk and no disk groups, respectively. Pain scores were significantly different (P < 0.001) in compressing disk (median, 10; IQR, 5-20) and no compressing disk (median, 30; IQR, 20-40) groups. The median satisfaction score was 5 in both groups. No complications occurred during follow-up.

CONCLUSION

Compressing a 3D-printed disk against the skin may reduce intradermal needle pain and offers an effective alternative for nerve block induction.

Effectiveness of physical stimulation for reducing injection pain in adults receiving intramuscular injections: a systematic review and meta-analysis

OBJECTIVE

The objective of this review was to synthesize the best available research evidence regarding the effectiveness of physical stimulation for reducing injection pain in adults receiving intramuscular injections.

INTRODUCTION

Pain associated with intramuscular injections continues to be a challenge for nurses. Various physical stimulation methods to alleviate pain and improve satisfaction for patients receiving intramuscular injections have been reported; however, the evidence surrounding the effectiveness of these methods remains inconclusive.

INCLUSION CRITERIA

This systematic review considered randomized and quasi-experimental studies that used any physical stimulation strategies (eg, skin tapping, manual pressure, massage, pinch, traction) for adults aged 18 years and over receiving intramuscular injections. Studies that evaluated pain using validated instruments were considered for inclusion.

METHODS

A three-step search strategy was conducted. MEDLINE, Embase, CINAHL, the Cochrane Library (Cochrane CENTRAL), Google Scholar, Dissertation Abstracts International, ProQuest Dissertations and Theses, and MedNar were searched from inception until 2020. We restricted the inclusion of studies to trials published in English. Two independent reviewers conducted the critical appraisal of eligible studies using the JBI checklists for randomized controlled and quasi-experimental trials. Data were extracted using the JBI data extraction tool, and meta-analysis and subgroup analysis were undertaken, where appropriate.

RESULTS

Twenty-five studies were included with a total sample size of 1956 patients. Pooled results demonstrated that pain was significantly less with the use of the Helfer skin tap technique compared to no intervention (two studies; RR 0.73; 95% CI 0.66, 0.81; P <0.00001) or standard intervention (three studies; SMD -2.25; 95% CI -3.65, -0.85; P =0.002). Intervention with acupressure using standard treatment as control showed significant reduction in pain intensity (MD -4.78; 95% CI -5.32, -4.24; P <0.00001). Similarly, pain was significantly lower with manual pressure (two studies; SMD -0.42; 95% CI -0.69, 0.15; P =0.002) when compared to standard treatment. Pain scores were significantly lower in patients who received pinch technique, ShotBlocker, massage, or combination intervention (skin traction, pressure, and rapid muscle release) compared with no intervention, standard treatment, or placebo control.

CONCLUSIONS

The evidence from this review demonstrates that physical stimulation - particularly the Helfer skin tap technique, acupressure, manual pressure, pinch technique, ShotBlocker, massage, and combination - can significantly lower intramuscular injection pain; however, this is based on low or very low certainty of evidence.

The comparative effects of ball squeezing and cartoon watching in pain management in children during intramuscular injection: A randomized control trial

This study was designed as a randomized controlled trial to investigate the comparative effect of ball squeezing and watching cartoons on pain management in children during intramuscular injection. The population of the study was comprised of 6-12 years old children who came to emergency for intramuscular injection. Power analysis was performed by G*Power program. Approximately 147 protocols completed with 6-12 years old children (each group 49 children). In the study, a questionnaire including child and socio-demographic characteristics their experiences of hospitalization data and Facial Pain Scale- Revised (FPS-R), Visual Analog Scale (VAS), and ball (for squeezing) were used. According to the results of the study, the FPS-R score during the procedure was the lowest in the stress ball group and was statistically significant (p˂0.05). The lowest VAS scores during the procedure the lowest score was in the stress ball group and the differences between the relevant groups were statistically significant (p˂0.05). It was determined that squeezing the ball and watching cartoons were effective in reducing pain during injection, however, the ball squeezing group had the lowest pain level. Among non-pharmacological methods, ball squeezing can be preferred as a practical and effective method, especially by pediatric nurses, in reducing pain during intramuscular injection in children.

Comparative Study of the Effect of Lidocaine Spray and Ice Spray on the Pain Intensity During Intramuscular Injection: A Randomized Clinical Trial

BACKGROUND

Intramuscular injection is one of the most common, invasive, and painful ways to deliver medicine to the body.

AIM

Since one of the nurse's duties is to employ different methods to reduce pain caused by treatment procedures, this study was conducted to determine the effect of lidocaine spray and ice spray on pain intensity at the muscle injection site.

METHOD

A clinical trial was performed on 90 patients presenting to outpatient clinics of Neyshabur hospitals. The samples were selected using a computerized table of random numbers, and each participant was randomly assigned to one of the control, lidocaine spray, and ice spray groups. Pain severity was measured immediately after intramuscular injection using a numerical pain scale. Descriptive statistics along with statistical tests (chi-square, Fisher, etc.) were used to analyze the data in the R environment version 3.6.2. Ordinal logistic regression was used to compare pain intensity in the three groups by adjusting the effect of age variables and sensory disorders.

RESULTS

The mean pain intensity was 3.44 without intervention, 2.63 with lidocaine spray, and 2.27 with ice spray. Statistical tests indicated a significant difference in pain intensity of intramuscular injection between the ice group and the control group (p = .010). Although lidocaine spray reduced the pain intensity, its effect was insignificant compared with the control group.

CONCLUSIONS

Both ice and lidocaine spray can be effectively used to reduce the intensity of intramuscular injection pain; however, it seems that ice spray is a more effective, safe, and affordable method.

Comparison of cold spray and shotblocker to reduce intramuscular injection pain: A randomized controlled trial

WHAT IS KNOWN AND OBJECTIVE

It is important to identify effective, easy-to-use and cost-effective non-pharmacological methods in the management of pain caused by medical interventions. The purpose of this study is to compare the effects of cold spray and ShotBlocker on pain in adults in reducing pain caused by intramuscular injection in the adult emergency department.

METHODS

This is a randomized controlled trial with two experimental groups, two placebo groups and a control group. The study was conducted on 195 adults who received diclofenac sodium injections. In the study, the injection procedure was performed by following the same injection protocol in all five groups. In the injection process, cold spray or ShotBlocker was used in the intervention groups based on the group, and cold spray with distilled water or the smooth surface of the ShotBlocker was used in the placebo groups. Following the injection, the pain caused by the injection was evaluated using the Visual Analog Scale.

RESULTS AND DISCUSSION

The study was completed with the remaining 195 patients. In the study, the average pain scores due to injection of the individuals in the cold spray group were lower than those of the control group (p < 0.05). There was no statistically significant difference between the pain score averages due to injection of the individuals in the ShotBlocker group and cold spray, control, ShotBlocker placebo and cold spray placebo groups.

WHAT IS NEW AND CONCLUSION

The routine use of a fast-acting, cost-effective and easy-to-use method, cold spray, to reduce pain in the intramuscular injection will be beneficial in increasing patient satisfaction and quality of care.

A Comparison of Two Different Tactile Stimulus Methods on Reducing Pain of Children During Intramuscular Injection: A Randomized Controlled Study

INTRODUCTION

Pediatric patients in the emergency department often require intramuscular injection procedures, which may lead to pain, fear, and anxiety. The purpose of this study was to test a novel nonpharmacological intervention to reduce needle-related pain in the pediatric emergency department.

METHODS

The study was conducted as a parallel-group, randomized controlled design. The study population consisted of 159 children aged 7 to 10 years cared for in the emergency department who received an intramuscular injection of ampicillin/sulbactam. The children were randomly assigned to Palm Stimulator, ShotBlocker, or control groups. The children's preprocedure fear levels were evaluated using the Children's Fear Scale, and their perceived pain levels during the procedure were evaluated using the Faces Pain Scale-Revised and Visual Analog Scale. Parents and observers also completed the pain level scores.

RESULTS

According to all raters (child, parent, and observer), the Palm Stimulator group had the lowest mean Faces Pain Scale-Revised score averages (P < .001). The Visual Analog Scale score averages of the children in the Palm Stimulator group (Visual Analog Scale: M = 27.94, standard deviation = 19.13) were statistically significantly lower than the ShotBlocker (Visual Analog Scale: M = 46.07, standard deviation = 24.96) and control group (Visual Analog Scale: M = 53.43, standard deviation = 29.01) score averages (F = 14.94, η² = 0.16, P = .001).

DISCUSSION

The results of this study support the effectiveness of the Palm Stimulator to reduce perceived pain in children during intramuscular injection administration in the pediatric emergency department.

The Effectiveness of a Non-Invasive Shot Blocking Device for Reducing Pain of In-office Injections in Hand Surgery

Background: The gate control theory asserts that non-painful stimuli can block pain perception. The ShotBlocker™ device is a plastic disk with blunt projections that rests on the skin, and we hypothesize that it will reduce pain during hand injections. Methods: This is a prospective randomized trial of 117 patients undergoing injections for common hand conditions. Patients were randomized into 3 groups: device, placebo (device with projections removed), and control. Patients recorded on an analog pain scale the pain severity of the injection, as well as their most recent tetanus shot. A normalized pain score was obtained from the difference between the injection and tetanus shot pain scores. The mean non-normalized and normalized scores for each treatment group were compared to the control group using the Wilcoxon signed rank test. Results: There were 91 women and 26 men. Common diagnoses included trigger finger (n = 53), DeQuervain's tendonitis (n = 33), and basal joint arthritis (n = 22). The groups did not differ significantly in age, gender, or diagnosis. Mean pain score in the device group was 5.2 out of 10, and it was 5.7 for the control group. The normalized pain score in the device group was significantly lower than the control group. Normalized and non-normalized pain scores for the placebo group were not significantly lower than the control group. Conclusions: The shot blocking device effectively reduced pain of injection versus controls when pain scores were normalized for pain tolerance. The modified device did not reduce the pain of injection, suggesting that gate control is the mechanism of action.

Effectiveness of Two Different Methods on the Perceived Pain and Satisfaction During Intramuscular Antibiotic Injection: ShotBlocker and Local Vibration

In this study aimed to examine the effectiveness of ShotBlocker and local vibration on the perceived pain and satisfaction during intramuscular antibiotic injection. The sample of the randomized controlled experimental study consisted of 100 patients (32 in vibration group, 35 in ShotBlocker group, 33 in control group) who applied to the adult emergency clinic for antibiotic (amoxicillin/cefuroxime sodium) injection between April and May 2021. The study data were collected using the Structured Information Form, VAS for Pain and VAS for Satisfaction. CONSORT statement was followed for reporting. After the intramuscular antibiotic injection, a significant difference was found between the groups in terms of the mean scores of VAS for Pain and VAS for Injection Satisfaction (p < .001). It was determined that local vibration application was more effective in reducing the pain and in increasing satisfaction that occurs during intramuscular antibiotic injection according to ShotBlocker and control groups.

Shotblocker Use in Emergency Care: A Randomized Clinical Trial

This study was conducted to evaluate the effect of ShotBlocker on the intramuscular injection pain and satisfaction in emergency adult patients. This research was designed as a randomized controlled, double-blind, experimental study. The study was conducted with 74 patients who applied to the adult emergency department. Patients were randomized to ShotBlocker and control groups. Patient Assessment Form, Visual Analog Scale, and Visual Analog Patient Satisfaction Scale were used. The mean scores of postinjection pain and satisfaction level were analyzed between the groups; it was determined that while postinjection pain mean score of the experimental group was statistically significantly lower than that of the control group (p = 0.0001), satisfaction scores were statistically significantly higher in the experimental group than in the control group (p = 0.004). When the correlation between the intragroup Pain Scores (VAS) and the Satisfaction Scores (VAS) of the groups after injection was examined, a statistically significant and inverse correlation was found (p < 0.05). It was determined that ShotBlocker was effective in reducing intramuscular injection pain and increasing satisfaction levels.

The Effect of ShotBlocker Application on Intramuscular Injection Pain in Adults: A Meta-Analysis

This meta-analysis study was conducted to determine the effects of ShotBlocker application during administration of intramuscular injections to adult patients for providing an evidence-based practice. The PubMed, Scopus, Science Direct, Ovid and Google Scholar databases were used for the literature review. The literature review was conducted by two researchers using the key phrases intramuscular injection AND ShotBlocker AND pain AND adults. According to the result of the meta-analysis, the pain levels in the experiment group in which ShotBlocker was used during IM injection to adult patients was found to be significantly different in comparison to the control group (SMD = -0.769, 95% CI = -1.449 to -0.090, p = .027). As a result of the meta-analysis, it was found that ShotBlocker application in IM injection in adult patients reduced patients' pain intensity. High-quality studies conducted with appropriate research methods are required for achieving a more comprehensive and effective result.

Effectiveness of physical stimulation on injection pain in adults receiving intramuscular injections: a systematic review protocol

OBJECTIVE

The objective of this review is to evaluate the effectiveness of physical stimulation on injection pain in adults receiving intramuscular injections.

INTRODUCTION

Intramuscular injections are the most commonly used modality for administration of pharmacological treatments. Despite this, pain from intramuscular injections is the most commonly reported side effect. Reducing patients' pain from intramuscular injections is important; however, the challenge is in selecting from the current methods available to alleviate pain, which are varied. The findings of this review may identify the most effective physical stimulation method to reduce the side effect of pain from an intramuscular injection.

INCLUSION CRITERIA

This review will consider studies that include adults aged 18 years and over that use physical stimulation interventions during intramuscular injections. Any physical stimulation strategies used during intramuscular injections including devices, skin tapping, manual pressure, massage, pinch, and traction will be considered. Studies that evaluate pain using validated tools such as pain scales will be included.

METHODS

The review will undertake to find both published and unpublished studies. The key information sources to be searched are MEDLINE, Embase, CINAHL, the Cochrane Library, Cochrane Central Register of Controlled Trials, Google Scholar, Dissertation Abstracts International, ProQuest Dissertations and Theses, and MedNar. Two independent reviewers will conduct a critical appraisal of eligible studies, assess the methodological quality, and extract the data. Studies will, where possible, be pooled in a statistical meta-analysis.

The effect of intramuscular injection technique on injection associated pain; a systematic review and meta-analysis

AIM

To review the effect of different intramuscular injection (IMI) techniques on injection associated pain, in adults.

METHODS

The review protocol was registered on PROSPERO (CRD42019136097). MEDLINE, EMBASE, British Nursing Index and CINAHL were searched up to June 2020. Included studies were appraised and a meta-analysis, where appropriate, was conducted with a random effects model and test for heterogeneity. Standardised mean difference (SMD) with a 95% confidence interval in reported injection pain (intervention cf. control) was reported.

RESULTS

29 studies were included in the systematic review and 20 studies in the meta-analysis. 13 IMI techniques were identified. 10 studies applied local pressure to the injection site. Of these, applying manual pressure (4 studies, SMD = -0.85[-1.36,-0.33]) and Helfer (rhythmic) tapping (3 studies, SMD = -2.95[-5.51,-0.39]) to the injection site reduced injection pain, whereas the use of a plastic device to apply local pressure to the skin (ShotBlocker) did not significantly reduce pain (2 studies, SMD = -0.51[-1.58,0.56]). Acupressure techniques which mostly involved applying sustained pressure followed by intermittent pressure (tapping) to acupressure points local to the injection site reduced pain (4 studies: SMD = -1.62[-2.80,-0.44]), as did injections to the ventrogluteal site compared to the dorsogluteal site (2 studies, SMD = -0.43[-0.81,-0.06]). There was insufficient evidence on the benefits of the 'Z track technique' (2 studies, SMD = -0.20[-0.41,0.01]) and the cold needle technique (2 studies, SMD = -0.73[-1.83,0.37]) on injection pain. The effect of changing the needle after drawing up the injectate on injection pain was conflicting and warming the injectate did not reduce pain. Limitations included considerable heterogeneity, poor reporting of randomisation, and possible bias in outcome measures from unblinding of assessors or participants.

CONCLUSIONS

Manual pressure or rhythmic tapping over the injection site and applying local pressure around the injection site reduced IMI pain. However, there was very high unexplained heterogeneity between studies and risk of significant bias within small studies.

Meditation Monologue can Reduce Clinical Injection-Related Anxiety: Randomized Controlled Trial

Background.

Strategies to reduce anxiety prior to injection procedures are not well understood. The purpose is to determine the effect of a meditation monologue intervention delivered via phone/mobile application on pre-injection anxiety levels among patients undergoing a clinical injection. The following hypothesis was tested: patients who listened to a meditation monologue via phone/mobile application prior to clinical injection would experience less anxiety compared to those who did not.

Methods.

A prospective, randomized controlled trial was performed at an orthopedics and sports medicine clinic of a tertiary level medical center in the New England region, USA. Thirty patients scheduled for intra- or peri-articular injections were randomly allocated to intervention (meditation monologue) or placebo (nature sounds) group. Main outcome variables were state and trait anxiety inventory (STAI) scores and blood pressure (BP), heart rate, and respiratory rate.

Results.

There were 16 participants who were allocated to intervention (meditation monologue) while 14 participants were assigned to placebo (nature sounds). There was no interaction effect. However, a main time effect was found. Both state anxiety (STAI-S) and trait anxiety (STAI-T) scores were significantly reduced post-intervention compared to pre-intervention (STAI-S: p = 0.04, STAI-T: p = 0.04). Also, a statistically significant main group effect was detected. The pre- and post- STAI-S score reduction was greater in the intervention group (p = 0.028). Also, a significant diastolic BP increase between pre- and post-intervention was recorded in the intervention group (p = 0.028), but not in the placebo group (p = 0.999).

Conclusion.

Listening to a meditation monologue via phone/mobile application prior to clinical injection can reduce anxiety in adult patients receiving intra- and peri-articular injections. Registration:ClinicalTrials.gov NCT02690194

Effect of family presence on pain and anxiety levels among patients during invasive nursing procedures in an emergency department at a public hospital in Western Iran

Introduction

It is widely accepted that pain is the most common complaint during invasive nursing procedures, which causes anxiety in patients. The purpose of this study was to determine the effect of family presence on the level of pain and anxiety of patients during invasive nursing procedures in an emergency centre in 2019.

Methods

The present non-randomized controlled clinical trial was conducted on 70 patients referred to emergency centre at selected hospital affiliated to Kermanshah University of Medical Sciences, Iran, in 2018, who were selected by convenience sampling method and then randomly assigned into two groups of intervention (even days) and control (odd days). The invasive nursing procedure was performed for the intervention group in the family presence for physical and psychological support and for the control group without the family presence. Data collection tools were the Spielberger State-Trait Anxiety Inventory (STAI) and the Visual Analogue Scale (VAS). SPSS version 23 software was used to compare the mean scores of pain and anxiety using independent t-test.

Results

The mean pain score after the invasive procedure had no significant difference between the intervention group (3.9 ± 1.5) and the control group (4.7 ± 1.9) (P = 0.073). In the intervention group, the mean score of anxiety after invasive procedure was significantly lower than before the invasive procedure (P = 0.028), whereas the control group showed no change (P = 0.556).

Conclusion

The family presence during the invasive nursing procedures reduced the anxiety of patients but had no effect on their pain. Emergency nurses can take advantage of family presence during invasive procedures as a non-pharmacological intervention to reduce patients' anxiety.

Virtual reality and distraction cards to reduce pain during intramuscular benzathine penicillin injection procedure in adults: A randomized controlled trial

AIM

The aim of this study was to determine the effect of using three-dimensional videos with virtual reality glasses and distraction cards including optical illusion pictures on patients' pain and satisfaction levels during intramuscular benzathine penicillin injection.

DESIGN

A randomized controlled trial.

METHOD

The study population consisted of 91 patients who were prescribed intramuscular benzathine penicillin medication. The participants were stratified by gender and assigned to three groups (control, virtual reality and distraction cards groups). The visual analogue scale was used to assess pain and patient satisfaction. A one-way analysis of variance and Dunnett's post hoc tests were used to compare the pain and satisfaction levels by group.

RESULTS

The mean pain was 6.67 (2.17) in the control group, 4.4 (2.71) in the distraction cards group and 4.93 (3.07) in the virtual reality group and the difference was statistically significant (F = 5.84, p ˂ .01). The average of the satisfaction levels in the groups was 3.57 (2.23) in the control group, 7.13 (2.86) in the distraction cards group and 8.07 (2.55) in the virtual reality group. The difference between the satisfaction levels was statistically significant (F = 25.77, p ˂ .01).

CONCLUSION

The three-dimensional videos with virtual reality glasses and distraction cards including optical illusion pictures were effective in reducing pain associated with intramuscular benzathine penicillin injection and increasing patient satisfaction.

IMPACT

The results of this study will contribute to evidence-based nursing practices for the pain associated with intramuscular benzathine penicillin injection.

Comparison of the efficacy of ShotBlocker and cold spray in reducing intramuscular injection-related pain in adults. A prospective, randomized, controlled trial

Objectives:

To compare the efficacy of ShotBlocker and cold spray in reducing intramuscular (IM) injection-related pain in adults.

Methos:

A prospective, randomized, controlled study carried out between January 2018 and March 2018 at the Department of Emergency Medicine, Acibadem Mehmet Ali Aydinlar University, School of Medicine, Istanbul, Turkey. Adult patients receiving IM injection of diclofenac sodium (75 mg/3 ml) were included. The patients were randomized into 3 groups: ShotBlocker, cold spray, and control. Each group comprised 40 patients. Patients were instructed to rate the intensity of IM injection-related pain using a 100-mm visual analog scale (VAS). Visual analog scale scores of the patients were statistically analyzed.

Results:

Visual analog scale scores were lower in the ShotBlocker (11 mm) and cold spray (10 mm) groups than in the control group (31 mm) (p=0.001). There were no significant differences in VAS scores between the ShotBlocker and cold spray groups. The operators’ responses revealed that ShotBlocker was more difficult to administer than cold spray.

Conclusion:

ShotBlocker is an effective non-pharmacological method that reduces IM injection-related pain and is similar in efficacy, to cold spray.

Feasibility of a pilot intervention to reduce pain and syncope during adolescent vaccination

PURPOSE

Vaccines recommended for adolescents are considered safe and effective, however administration may occasionally result in acute pain at the injection site or syncope (fainting). These adverse effects pose a risk to patient safety and are potential barriers to adherence to future vaccinations. We assessed a novel intervention designed to help prevent acute pain and syncope associated with adolescent vaccinations.

METHODS

We conducted a 3-month pilot study to assess the feasibility and acceptability of a vaccination comfort menu within two Kaiser Permanente Northwest pediatric clinics. The menu offered a variety of comfort items (e.g., cold packs, squeeze balls) that children could select prior to their vaccination. We surveyed parents of recently vaccinated adolescents and interviewed providers to assess the implementation and effectiveness of the intervention.

RESULTS

Response rate for the parent survey was 33% (378/1136). Only 20% of the parents reported that their provider offered the comfort menu during the vaccination visit. Approximately 50% of the adolescents who were offered the menu selected a comfort item and most of these participants reported that the item was very (35%) or somewhat (38%) helpful in improving their vaccination experience. Per provider interviews, common barriers to implementing the intervention included lack of time and convenience, and the brevity of the pilot period.

CONCLUSIONS

The comfort menu may improve the vaccination experience of youth and increase the likelihood of adherence with future vaccinations. However, only 20% of the parents reported that their provider offered the menu during the vaccination visit. Additional research is needed to determine the feasibility of implementing this intervention on a larger scale, as well as assessing whether the intervention has a significant impact on reducing adverse events.

Effectiveness of ShotBlocker for Immunization Pain in Full-Term Neonates: A Randomized Controlled Trial

Nonpharmacologic strategies exist to manage procedural pain in healthy newborn infants. The aim of this prospective randomized controlled trial (RCT) was to examine the efficacy of ShotBlocker for managing injection pain associated with the first intramuscular hepatitis B vaccine given to healthy full-term neonates. This randomized controlled trial study was conducted in a private university hospital in Istanbul, Turkey, in which 100 healthy term neonates were randomly assigned to either a ShotBlocker (n = 50) or control group (n = 50). The Neonatal Infant Pain Scale scores of the neonates in the ShotBlocker and control groups were compared before, during, and after the injections, and the physiological parameters were compared before and after the procedure. The pain scores of the neonates during (ShotBlocker group: 1.64 ± 0.80; control group: 2.96 ± 0.73) and after (ShotBlocker group: 0.74 ± 0.66; control group: 1.42 ± 0.76) the injection procedure were lower in the ShotBlocker group than in the control group (P = .000). The postinjection heart rate in the infants in the ShotBlocker group (145.02 ± 13.50) was found to be lower than in those for whom ShotBlocker was not used (150.24 ± 13.36) (P = .05). The use of ShotBlocker during the hepatitis B vaccine in term neonates is effective in reducing the acute pain.

The effect of air-lock technique on pain at the site of intramuscular injection

OBJECTIVES

To investigate the effects of air-lock technique (ALT) on pain of intramuscular (IM) injection delivered to the ventrogluteal and dorsogluteal site (DS).

METHODS

A randomized controlled trial design was used to assess the pain intensity associated with IM injections administered using 2 different methods and injection sites. Recruitment of patients was carried out between April and August 2013 at the Department of Brain Surgery, Cekirge State Hospital, Bursa, Turkey. The sample comprised 60 patients who developed no complications at the IM site, and had no illness that could affect their perception of pain. The patients were randomly divided into 2 groups of 30 patients. Patients in the first group received injections in the ventrogluteal site (VS), while the DS was used for injections in the second group. Patients in each group received 2 injections, one using ALT and one not using the technique. After each injection, the pain felt by patients during the injection was immediately assessed using a visual analog scale.

RESULTS

The mean pain score after injections to the DS by the ALT was 3.30 ± 2.70, while the mean pain score after injections to the VS using the same technique was 2.53 ± 2.52.

CONCLUSION

Although the difference between groups was not significant, the results of the study supported the idea that injections delivered to the VS by ALT are less painful than those delivered to the DS.
