EFFECTIVENESS OF ICE APPLICATION AT SELECTED ACUPOINT (LI-4) PRIOR TO INTRAMUSCULAR INJECTION ON LEVEL OF PAIN AMONG CHILDREN IN A SELECTED HOSPITAL, CHENNAI, TAMIL NADU, INDIA.

Immunization is an effective and safest way to prevent vaccine-preventable diseases and thereby reduce morbidity and mortality in children. Injections given for immunization are the most usual ground in order to abstract agony or pain, which is the fifth vital sign leading to long-term physically and psychologically detrimental effects. A basic experimental (control group only for post-test) design using the technique of probability of simple random sampling in order to obtain sample size 105 was conducted in an Immunization Clinic at a selected PHC, Tamil Nadu, India. Ice cube was applied for about 30 seconds that is enfolded with gauze and then injected intramuscularly to administer the IM vaccine. In order to assess the pain level, an observation checklist based on Children's Hospital Eastern Ontario pain scale and Wong Baker's Faces pain scale was used. The study results manifest the higher statistical difference in the level of children's pain between the control groups and the experimental groups at a significance level of p<0.001. In order to reduce the pain level, the application of ice at LI-4 acupoint is effective. The children who are being vaccinated pass through stressful events through the application of an intramuscular injection. The findings revealed that ice application at LI-4 acupoint was very effective in pain reduction, which is a simple, safe, non-invasive, very efficient, easy-to-administer intervention and cost-effective without side effects than any other pharmacological pain intervention.

Effect of the Helfer skin tap technique on pain, anxiety, and fear in children undergoing intramuscular injection: An open-label randomized controlled study.

BACKGROUND: Intramuscular injections, which children frequently experience during hospitalization, are one of the most significant causes of pain. Pain control is an important part of care. Therefore, it is necessary to provide practical methods in the field of nursing care to reduce injection-related pain. AIM: This study aimed to determine the effect of the Helfer skin tap technique on pain, anxiety, and fear in children undergoing intramuscular injection. METHOD: This randomized controlled clinical study (NCT05250804) was conducted in a pediatric emergency department between January and July 2022. A total of 64 children aged 4-10 years were randomly divided into two groups: 32 children in the Helfer skin tap group (HG), and 32 children in the control group (CG). Data were collected using the Wong-Baker FACES Pain Rating Scale, the Child Anxiety Scale-State, and the Child Fear Scale. RESULTS: After the intramuscular injection, children in the HG had significantly lower levels of pain, anxiety, and fear than those in the CG, with mean scores of 3.25±1.50 versus 5.18±1.51, 5.87±1.56, versus 6.23±1.46, and 1.68±0.53 versus 3.15±0.76, respectively (p<0.001 for all scores). CONCLUSION: The Helfer skin tap technique has positive effects on pain, anxiety, and fear in children during intramuscular injection. This technique can be used by nurses to reduce the pain, anxiety, and fear felt by children receiving an intramuscular injection.

A 25-Year-Old Military Recruit with Isolated Myositis Following Routine Chemoprophylaxis with Intramuscular Benzathine Penicillin G.

BACKGROUND Myositis is an inflammatory myopathy that can be caused by a variety of drugs, diseases, and toxins. The U.S. military uses chemoprophylaxis with intramuscular penicillin G to prevent group A streptococcal infection. We present a case of penicillin G-induced myositis, a rare cause of drug-induced myositis with limited discussion in the medical literature. CASE REPORT A 25-year-old man with no pertinent medical history presented to the Emergency Department with right hip and leg pain after receiving a single dose of intramuscular penicillin G as part of standard prophylaxis for group A streptococcal infection during basic military training. He reported pain and leg weakness that was exacerbated by physical exertion and weight bearing but had no systemic symptoms, such as fevers or chills. Initial radiographs of the hip were normal; however, subsequent magnetic resonance imaging of the hip revealed intramuscular edema and features consistent with myositis of the right proximal thigh and hip musculature. He was admitted for isolated right gluteal myositis, attributed to his preceding local penicillin injection. He recovered with symptomatic care over the following 2 weeks, with return to baseline function. CONCLUSIONS This case highlights a rare complication of intramuscular penicillin G as a cause of acute isolated myositis. It serves to inform physicians of this rare complication and to recommend the consideration of intramuscular penicillin G as a causative etiology in individuals presenting with myositis and recent penicillin G exposure.

Do repetitive botulinum neurotoxin injections induce muscle fibrosis? Sonographic observation of the masseter muscle.

OBJECTIVE: In the esthetic field, the masseter muscle is commonly targeted by botulinum neurotoxin for facial contouring. However, multiple botulinum neurotoxin injections have been reported to cause muscle fibrosis. Ultrasonography can be useful for clinical consideration in such cases. MATERIALS AND METHODS: This study presents nine cases of masseteric fibrosis caused by repeated botulinum neurotoxin injections with ultrasonographic analysis of full and partial masseteric fibrosis. RESULTS: Repetitive botulinum neurotoxin injections resulted in reduced masseter muscle volume, which frequently appeared hyperechoic on ultrasonography. The hyperechoic region was mostly located in the deep and posterior portions; however, in some cases, it was observed throughout the muscle, including the superficial, deep, or both areas. CONCLUSION: The fibrotic masseter muscles appear hyperechoic, and ultrasonography is necessary to analyze the degree and location of fibrosis. Predictions can be made for cases in which botulinum neurotoxin injections may have less of an effect after ultrasonography. Because muscle fibrosis can be localized, it is necessary to confirm the degree and location of fibrosis before determining the effective area of injection. In clinical practice, muscle fibrosis may be visible in a specific area where blind injections are administered.

Variation in the Guidelines for the Acute Management of Anaphylaxis in Pediatric Patients: An International Narrative Review.

OBJECTIVES: Evidence-based guidelines have been created and disseminated by multiple organizations to standardize the care of pediatric patients with anaphylaxis. Differences across these guidelines can cause confusion and potentially errors in clinical practice leading to patient harm. The aim of this study was to describe and identify patterns of variation in the current guidelines. METHODS: A narrative review with 3 major components was designed. First, a narrative review of current, peer-reviewed, guidelines published by national and international allergy and immunology, pediatric, and emergency medicine organizations was performed. That was followed by a gray literature review of guidelines by resuscitation councils and national health organizations. The third component focused on the translation of these guidelines at local and institutional levels by reviewing clinical pathways published by academic institutions. RESULTS: With regard to the fixed epinephrine autoinjector dosing, 50% (6 of 12) of the reviewed guidelines offered weight-based and 41.7% (5 of 12) age-based dosing recommendations. Furthermore, different weight cutoffs for the 0.15- and 0.3-mg autoinjectors were identified among guidelines. Variation was identified in the description of intramuscular epinephrine concentration ("1:1000," "1 mg/mL," or both), the recommended concentration for intravenous administration ("1:10,000" or "1:1000"), or the rate of infusion or titration. Eight of the 12 guidelines (66.7%) recommend a dose in milligrams, and 33.3% (4 of 12) in micrograms. Five of 12 (41.7%) used both milliliters and milligrams or micrograms. CONCLUSIONS: Notable variation in the current guidelines for the acute management of anaphylaxis in the pediatric population was identified. Flagging this variability could help inform a consensus-based approach toward harmonization of guidelines, which in turn could streamline the management of anaphylaxis in pediatric patients across the United States, Canada, Ireland, the United Kingdom, Europe, Australia, and New Zealand, and hopefully prevent errors and mitigate patient harm.

Three Episodes of Presumed Culture-Negative Septic Arthritis Following Intramuscular Antipsychotic Injections: A Case Report.

CASE: We present a male patient of low socioeconomic status and Maori ethnicity who experienced 3 episodes of presumed culture-negative septic arthritis of the native hip between ages 43 and 52 years. Each episode occurred within 3 weeks of intramuscular antipsychotic injection into the ipsilateral gluteal muscles. The right hip was involved in 2 presentations and the left hip in 1 presentation. No coexisting infection or underlying immune suppression was identified, and at follow-up 2 years after the last episode, he has no sequelae of septic arthritis. CONCLUSION: This report describes 3 episodes of presumed culture-negative septic arthritis after intramuscular antipsychotic injection.

Neuropathy following intramuscular injections: a clinical and neurophysiological study from a tertiary care centre in Pakistan.

OBJECTIVE: To assess the clinical and neurophysiological profile of peripheral nerve injuries in patients following intramuscular injections. METHODS: The descriptive, cross-sectional study was conducted at the Department of Neurology, Mayo Hospital, Lahore, Pakistan, from July 2019 to January 2021, and comprised adult patients of either gender with isolated peripheral nerve injuries following intramuscular injections. Nerve conduction studies were performed for each patient. Data was analysed using SPSS 26. RESULTS: Of the 99 patients, 59(59.6%) were males and 40(40.4%) were females. The mean age was 26.7+/-18.1 years, 34(34.3%) patients were under weight and 78(78.8%) were either illiterate or had low literacy level. Radial nerve was involved in 56(56.6%) cases, followed by sciatic in 39(39.4%) and axillary nerve 4(4.04%). Overall, 14(14.14%) injection had been administered by doctors, while the other 85(85.85%) were given by paramadics. Marked reduction in compound muscle action potential 72(72.7%) and sensory nerve action potential 82(82.8%) was noted, while re-innervation was seen in 78(78.7%). CONCLUSIONS: Intramuscular nerve injuries can be greatly minimised by spreading awareness regarding safe injection techniques and strict implementation of standard operating procedures in hospitals and clinics.

Adverse effects of dorsogluteal intramuscular injection versus ventrogluteal intramuscular injection: A systematic review and meta-analysis.

AIMS: To determine adverse effects of ventrogluteal intramuscular injections versus dorsogluteal intramuscular injections. DESIGN: A systematic review and meta-analysis. METHODS: MEDLINE, EMBASE, CINHAL, CENTRAL, LILACS(BVS), BDENF (BVS), WoS, IRCTP(WHO), ClinicalsTrials.gov and PROSPERO databases were searched with no restriction on year or language. Preferred Reporting items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: A total of 1429 participants from 17 studies were included. The meta-analysis found that ventrogluteal injection site had significant relation to lower pain in 9 studies (SMD = -0.63, 95% CI = -0.87, -0.39), bleeding in 4 studies (SMD = -3.46, 95% CI = -6.07, -0.86) and hematoma in 2 studies; after 48 h (SMD = -0.25, 95% CI = -0.39, -0.11), and after 72 h (SMD = -0.16, 95% CI = -0.26, -0.06), if it was compared with dorsogluteal site injection. No differences were found when comparing the possibility of intramuscular injections given into de subcutaneous tissue. In three studies, ventrogluteal site did not significantly reduce the risk of subcutaneous injection (OR 0,62, 95% CI = 0.16, 2.41).

Injection Site Reactions Before and After Intramuscular Injection Technique Revision: A Postmarketing Analysis of NALDEBAIN® From 2017 to 2022.

BACKGROUND: The NALDEBAIN® has been available since 2017, and high incidence of injection reactions in the phase 3 study has been reported. Since the first year in the market, the injection site reactions were still the majority of adverse drug reactions (ADRs) in pharmacovigilance reports. The new intramuscular (IM) instruction and package was introduced in the middle of 2018. In this retrospective study, we analyzed the pharmacovigilance data and published postmarketing studies to investigate the impact of IM injection-related reactions in Taiwan between the period of 2017-2022. METHODS: Individual case safety reports (ICSRs) and ADRs were classified by system organ class and preferred term. The reporting rate of ICSRs was used to evaluate the impact of the new IM instruction and package. RESULTS: A total of 37 ICSRs were identified from pharmacovigilance reports. Among them, 51% of IM injection-related reactions were reported after one single dose of NALDEBAIN administration. The reporting rate of IM injection-related reactions in pharmacovigilance data dropped from 125.00 to 3.56 per ten thousand exposures after IM instruction and package revision in 2018. In addition, the percentage of IM injection-related reactions also reduced in postmarketing studies from 27.5% to 4.5%. There were no serious IM injection-related reactions found in the pharmacovigilance and postmarketing dataset. CONCLUSION: Injection site reactions were common after intramuscularly administered oil-based agents during the first year which is later markedly reduced by changing the length of the needle and injection education.

Botulinum neurotoxin injection in the deltoid muscle: application to cosmetic shoulder contouring.

BACKGROUND AND OBJECTIVES: This study describes the intramuscular nerve branching of the deltoid muscle in relation to shoulder surface anatomy, with the aim of providing essential information regarding the most appropriate sites for botulinum neurotoxin injection during shoulder line contouring. METHODS: The modified Sihler's method was used to stain the deltoid muscles (16 specimens). The intramuscular arborization areas of the specimens were demarcated using the marginal line of the muscle origin and the line connecting the anterior and posterior upper edges of the axillary region. RESULTS: The intramuscular neural distribution of the deltoid muscle had the greatest arborization patterns in the area between the horizontal 1/3 and 2/3 lines of the anterior and posterior deltoid bellies, and 2/3 to axillary line in middle deltoid bellies. The greatest part of the posterior circumflex artery and axillary nerve ran below the areas with the highest aborizations. CONCLUSION: We propose that botulinum neurotoxin injections should be administered in the area between the 1/3 and 2/3 lines of the anterior and posterior deltoid bellies, and 2/3 to axillary line on middle deltoid bellies. Accordingly, clinicians will ensure minimal dose injections and fewer adverse effects of the botulinum neurotoxin injection. Deltoid intramuscular injections, such as vaccines and trigger point injections, should ideally be adapted according to our results.

Long-acting antiretrovirals and HIV treatment adherence.

Intramuscular injection of long-acting cabotegravir and rilpivirine is a novel, long-acting antiretroviral therapy (ART) combination approved for use as a fully suppressive regimen for people living with HIV. Long-acting cabotegravir with rilpivirine ART has reduced required dosing frequency from once daily to once every month or every 2 months injections. This new era of long-acting ART, which includes other antiretrovirals and formulations in various stages of clinical development, holds tremendous promise to change the standard of HIV treatment. Although long-acting ART has high potential to be revolutionary in the landscape of HIV care, prevention, and treatment cascade, more data are needed to substantiate its efficacy and cost-effectiveness among patients at risk of non-adherence and across age groups, pregnancy, and post partum. Advocacy efforts and policy changes to optimise a sustained, high-quality, equitable reach of long-acting ART, especially in low-income and middle-income countries where most people living with HIV reside, are needed to realise the full benefits of long-acting ART.

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. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42020168586.

[Nicolau syndrome]. / Síndrome de Nicolau.

Nicolau syndrome is a rare complication of the parenteral application of various drugs. It is characterized by the appearance of pain, followed by edema, erythema, and then a necrotic plaque. We present the case of a 31-year-old male with this syndrome, after the application of intramuscular benzathine penicillin. The diagnosis was supported by the biopsy. He received treatment with enoxaparin and cilostazol with subsequent improvement.

El síndrome de Nicolau es una complicación infrecuente de la aplicación parenteral de diversos fármacos. Se caracteriza por la aparición de dolor, seguido de edema, eritema y luego una placa necrótica. Se reporta el caso de un hombre de 31 años que presenta este síndrome luego de la aplicación de penicilina benzatínica intramuscular. La biopsia apoyó el diagnóstico. Recibió tratamiento con enoxaparina y cilostazol con posterior mejoría.

Adverse effects following botulinum toxin A injections in children with cerebral palsy.

The study aimed to analyze the adverse events associated with botulinum toxin A (BoNT-A) injections in children with cerebral palsy (CP). The literature search was completed using the Medline, PubMed, Google Scholar, Scopus, and Cochrane Library databases from the earliest date possible up to December 2021. Search terms included 'botulinum toxin', 'cerebral palsy', 'spasticity', 'adverse effects', 'side effects', 'undesirable effects', 'complications', 'lower limb', 'upper limb', and 'children' including combinations of index and free-text terms. Fifty-five studies were included in the study. Data on 6333 pediatric patients and more than 14 080 BoNT-A injections were collected. Respiratory symptoms and respiratory tract infections were the most frequently registered adverse events (AEs). Other common AEs included procedural/focal AEs, flu-like symptoms, and asthenia. Sentinel events including four cases of death were reported. AEs were more frequent and severe in high-dose patients; however, the capacity of BoNT-A to spread systemically remains unclear. Since severe adverse events are not common, further research is needed to collect more definitive clinical and homogeneous data to support the findings of the present research and clarify the safety profile of BoNT-A, especially regarding the incidence of respiratory issues and complications in GMFCS IV or V patients.

Ultrasound-guided lateral pterygoid muscle botulinum toxin: an injection for recurrent temporomandibular joint dislocation in a brain injury patient.

Botulinum toxin type A (BTX-A) injection using nerve stimulation or electromyography for recurrent temporomandibular joint (TMJ) dislocation has been reported for several years. However, using the available equipment like a nerve stimulator or an electromyograph is uncommon, and ultrasound guidance is convenient and requires no additional resources. In this report, we used ultrasound as a tool to achieve BTX-A injections in a patient with a traumatic brain injury to treat her TMJ dislocation. One week after the injections, she had no more dislocation. She remained symptom free during the 3 months of follow-up, and her clinical symptoms improved without significant complications. This is the first report using ultrasound guidance for BTX-A injections to treat recurrent TMJ dislocation. This treatment is an effective and safe technique that could be performed timely and locally without referral to a center with electromyography facilities.

[How to treat spasticity after stroke ?] / Comment je traite la spasticité après un accident vasculaire cérébral.

Spasticity is a form of hypertonia frequently encountered in patients who suffered from stroke and is a cause of functional limitation, contractures, osteoarticular deformations, pain and wounds. The first-line treatment of focal or multifocal spasticity consists in intramuscular injections of botulinum toxin type A in the muscles concerned, in association with positioning measures and physical therapy. Despite the fact this pathology is common, there is often a delay in the diagnosis, and consequently the treatment, leading to harmful consequences for the patient. In some specific indications, surgery can also be a therapeutic option. Finally, spasticity should be distinguished from other types of hypertonia, e.g. dystonia.

: La spasticité est une forme d'hypertonie, fréquemment rencontrée dans les suites d'un accident vasculaire cérébral. Elle peut être à l'origine de limitations fonctionnelles, de rétractions tendineuses, de déformations ostéoarticulaires, de douleurs et de plaies. Le traitement de première ligne de la spasticité focale ou multifocale repose sur l'injection intramusculaire de toxine botulique de type A dans les muscles entrepris, en association à des mesures de positionnement et à une prise en charge kinésithérapeutique. Malgré la fréquence de cette affection, elle est encore trop souvent reconnue, et donc traitée, tardivement, ce qui aboutit à des conséquences délétères pour le patient. Dans certaines indications précises, la chirurgie a également une place dans l'arsenal thérapeutique de la spasticité. Enfin, la spasticité ne doit pas être confondue avec les autres formes d'hypertonie, comme la dystonie.

Epidemiology and treatment outcomes in pediatric patients with post-injection paralysis.

BACKGROUND: Post-injection paralysis (PIP) of the sciatic nerve is an iatrogenic paralysis that occurs after an intramuscular injection, with resultant foot deformity and disability. This study investigates the epidemiology and treatment of PIP in Uganda. METHODS: Health records of pediatric patients surgically treated for PIP at the CoRSU Rehabilitation Hospital from 2013 to 2018 were retrospectively reviewed. Pre-operative demographics, perioperative management, and outcomes were coded and analyzed with descriptive statistics, chi-square for categorical variables, and linear models for continuous variables. RESULTS: Four-hundred and two pediatric patients underwent 491 total procedures. Eighty-three percent of reported injection indications were for febrile illness. Twenty-five percent of reported injections explicitly identified quinine as the agent. Although ten different procedures were performed, achilles tendon lengthening, triple arthrodesis, tibialis posterior and anterior tendon transfers composed 83% of all conducted surgeries. Amongst five different foot deformities, equinus and varus were most likely to undergo soft tissue and bony procedures, respectively (p=0.0223). Ninteen percent of patients received two or more surgeries. Sixty-seven percent of patients achieved a plantigrade outcome; 13.61% had not by the end of the study period; 19.3% had unreported outcomes. Those who lived further from the facility had longer times between the inciting injection and initial hospital presentation (p=0.0216) and were more likely to be lost to follow-up (p=0.0042). CONCLUSION: PIP is a serious iatrogenic disability. Prevention strategies are imperative, as over 400 children required 491 total surgical procedures within just six years at one hospital in Uganda.
