RESUMEN
AIM: To develop clinical practice recommendations for nurse-administered intramuscular injections in mental health. BACKGROUND: Intramuscular injection is the main route of long-acting injectable antipsychotics' administration that appear to improve the long-term prognosis of mental illness. Specific guidelines related to the nurse administration of intramuscular injections need to be updated and to explore not only the technical aspects of this procedure. DESIGN: A modified RAND/University of California Los Angeles (UCLA) appropriateness method Delphi study was conducted between October 2019 and September 2020. METHODS: A multidisciplinary steering committee conducted a literature review and developed a list of 96 recommendations. These recommendations were submitted in a two-round Delphi electronic survey to a panel of 49 experienced practicing nurses from five mental health hospitals in France. Each recommendation was rated for its appropriateness and applicability in clinical practice on a 9-point Likert scale. Consensus among nurses was evaluated. The steering committee discussed the results after each round and approved the final set of recommendations. RESULTS: A final set of 79 specific recommendations were accepted for their appropriateness and applicability in clinical practice. Recommendations were classified in five domains: legal and quality assurance aspects, nurse-patient relationship, hygiene, pharmacology, and injection technique. CONCLUSION: The established recommendations placed patients at the heart of the decisions concerning the intramuscular injection and underlined the need for specific training programs. Future research should focus on the integration of these recommendations in clinical practice, by both before-and-after studies and regular assessments of professional practices with relevant indicators. IMPACT: The recommendations developed for good nursing practices explored not only the technical aspects but integrated the nurse-patient relationship. These recommendations may impact usual practices of administration of long-acting injectable antipsychotics and most of them could be applied in many countries. NO PATIENT OR PUBLIC CONTRIBUTION: Due to the study design.

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.

AIMS AND OBJECTIVE(S): The objective of this systematic review was to determine the needle length required to reach the dorsogluteal muscle based on body mass index and sex. Our aim was to provide evidence-based recommendations to current intramuscular injection guidelines from the result(s) of this review. BACKGROUND: Studies worldwide are documenting reduced medication effectiveness due to improperly placed dorsogluteal intramuscular injections because of incorrect needle length, wrong site selection and/or obesity. Current intramuscular injection guidelines lack specific instructions according to weight or sex. While there are similar concerns with other injectable sites, this review focuses solely on adult dorsogluteal intramuscular injections. DESIGN: A systematic review of relevant literature of dorsogluteal intramuscular injections based on body mass index and sex. METHODS: This systematic review was reported using the PRISMA checklist 2020. The review protocol was registered with Center for Open Science (OSF). We analysed 1,412 articles from nine databases. We compared twelve studies that utilised computerised tomography or ultrasonography using The Johns Hopkins Evidence-Based Practice Model and Guidelines. RESULTS: A significant number of dorsogluteal intramuscular injections are administered into subcutaneous tissue rather than muscle because needles are too short for populations with body mass indexes over 25, especially women. Poor landmarking often results in improperly placed injections. CONCLUSIONS: To prevent administering a dorsogluteal intramuscular injection into subcutaneous tissue, women with a BMI of 25 and over require needles longer than 38 mm (1.5 inches). Men have less subcutaneous tissue in the dorsogluteal area and only require longer needles if BMI is 35 and over. If skin-to-muscle depth is questionable in either sex, an ultrasound-guided intramuscular injection is warranted for accurate dorsogluteal placement. Landmarking and needle length are key to appropriately placed IM injections. RELEVANCE TO CLINICAL PRACTICE: Dorsogluteal injections are often injected into subcutaneous tissue rather than muscle because needles are not long enough to reach muscle, especially in women. Critical elements that determine placement of intramuscular injections into muscle versus subcutaneous tissue are sex, BMI, needle length and landmarking. Medications delivered into subcutaneous tissue may have reduced bioavailability.

BACKGROUND: A randomized, controlled, phase 3b study (ALPINE) evaluated efficacy and safety of a 2-month formulation of aripiprazole lauroxil (AL) using a 1-day initiation regimen in patients hospitalized for an acute exacerbation of schizophrenia. Paliperidone palmitate (PP) was used as an active control. Exploratory endpoint assessments included severity of illness, positive and negative symptoms, quality of life, caregiver burden, and satisfaction with medication. METHODS: Adults were randomly assigned to AL 1064 mg q8wk or PP 156 mg q4wk as inpatients, discharged after 2 weeks, and followed through week 25. Exploratory efficacy measures included the 3 original PANSS subscales, Clinical Global Impression-Severity (CGI-S) subscale, and caregiver Burden Assessment Scale. Exploratory patient-reported outcomes (PROs) included the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) and the Medication Satisfaction Questionnaire. Within-group changes from baseline through week 25 were analyzed for AL and PP separately. PROs were summarized based on observed data. RESULTS: Of 200 patients randomized (AL, n = 99; PP, n = 101), 99 completed the study (AL, n = 56; PP, n = 43). For AL, PANSS subscale and CGI-S scores improved from baseline through week 25 (mean [SE] change from baseline at week 25: Positive, -7.5 [0.70]; Negative, -3.9 [0.46]; General, -11.8 [0.83]; CGI-S, -1.3 [0.12]). Caregiver burden also improved (mean [SD] changes from baseline at week 9: -8.4 [10.15]; week 25: -8.9 [12.36]). Most AL patients were somewhat/very satisfied with treatment at each timepoint (70.8%-74.7%); mean Q-LES-Q-SF total scores were stable in the outpatient period. For PP, results were similar: PANSS Positive, -7.3 (0.67); Negative, -3.6 (0.69); General, -10.9 (1.22); CGI-S, -1.4 (0.16); caregiver burden, week 9: -8.8 (11.89) and week 25: -9.2 (14.55); satisfaction with treatment, 64.7%-69.3%; and stable Q-LES-Q-SF scores. CONCLUSIONS: ALPINE patients initiating the 2-month AL formulation using the 1-day initiation regimen as inpatients and continuing outpatient care experienced schizophrenia symptom improvement, sustained patient satisfaction with medication, stable quality of life, and reduced caregiver burden. A similar benefit pattern was observed for PP. These results support the feasibility of starting either long-acting injectable in the hospital and transitioning to outpatient treatment.

Skeletal muscle injuries in competitive sports cause lengthy absences of athletes from tournaments. This is of tremendous competitive and economic relevance for both the athletes and their respective clubs. Therapy for structural muscle lesions aims to promote regeneration and fast-track return-to-play. A common clinical treatment strategy for muscle injuries is the intramuscular injection of calf blood compound and the homeopathic drug, Tr14. Although the combination of these two agents was reported to reduce recovery time, the regulatory mechanism whereby this occurs remains unknown. In this in vivo study, we selected a rat model of mechanical muscle injury to investigate the effect of this combination therapy on muscle regeneration. Gene expression analysis and histological images revealed that this combined intramuscular injection for muscle lesions can enhance the expression of pro-myogenic genes and proteins and accelerate muscle regeneration. These findings are novel and depict the positive effects of calf blood compound and the homeopathic drug, Tr14, which are utilized in the field of Sports medicine.

OBJECTIVE: To compare low-fidelity simulation/model and hybrid simulation techniques for teaching how to perform intramuscular injections. METHODS: The case control study was conducted at the Department of Midwifery, Adnan Menderes University, Aydin, Turkey, from May 2 to 25, 2018, and comprised students enrolled in the course of Basic Principles and Practices in Midwifery II. The students were randomly divided into intervention group A and control group B. Those in group A were taught intramuscular injection at an assembly which was prepared through hybrid simulation method, while those in group B made use of the model routinely employed in the midwifery programme. Data was collected using a descriptive characteristics form, the General Self-Efficacy Scale, the State Trait Anxiety Inventory and the Guide to Performing Intramuscular Injections into the Ventro-gluteal Site. Data was analysed using SPSS 20. RESULTS: Of the 73 students, 37(50.7%) were in group A and 36(49.3%) in group B. There was no difference in terms of age between the groups (p>0.05). Group A had a better total General Self-Efficacy Scale scores compared to group B (p<0.05). Mean score of group A in State-Trait Anxiety Inventory was lower than that of group B (p<0.05). The mean score of group A was also higher in the Guide to Performing Intramuscular Injections into the Ventrogluteal Site compared to group B (p<0.05). CONCLUSIONS: Students using a hybrid simulation method had better levels of self-efficacy and skill as well as lower levels of anxiety compared to those trained on the conventional method.

BACKGROUND: Penicillin G Benzathine (PGB) is the cornerstone of syphilis treatment. However, its intramuscular (IM) administration is associated with pain at the site of injection. The dilution of PGB with local anesthetics is recommended in some guidelines, but the evidence that supports it, particularly in adults and in HIV infection, is scarce. Preliminary clinical experience also suggests that the IM administration of PGB through increased needle gauges might improve its tolerability. The aim of the study to identify less painful ways of administering IM PGB in the treatment of syphilis in adults. METHODS: Multicenter, randomized, double-blinded clinical trial in patients diagnosed with primary syphilis that required a single IM injection of PGB 2400,00 IU. Patients were randomized to receive PGB diluted with 0.5 mL mepivacaine 1% (MV) or PGB alone, and both groups either with a long 19G or short 21G IM needle. The primary objective was the effect on local pain immediately after the administration through a visual scale questionnaire on pain (0 to 10). RESULTS: One hundred eight patients were included, 27 in each group. Ninety-four (94.4%) were male, and 41.7% were also HIV-infected. Mean age 36.6 years (SD 11). Significant differences in immediate pain intensity were observed when comparing the long 19G group with anesthesia (mean pain intensity, [MPI] 2.92 [CI 95% 1.08-4.07]) vs long 19G without anesthesia (MPI 5.56 [CI 95% 4.39-6.73), p < 0.001; and also between short 21G group with anesthesia (MPI 3.36 [CI 95% 2.22-4.50]) vs short 21G without anesthesia (MPI 5.06 [CI 95% 3.93-6.19]), p = 0.015). No significant differences in immediate pain were observed between 19G and 21G in the presence or absence of anesthesia (p = 1.0 in both cases). No differences were found between study arms after 6 and 24 h. CONCLUSIONS: The IM administration of 1% mepivacaine-diluted PGB induces significantly less immediate local pain as compared to PGB alone. The needle gauge did not have any effect on the pain. Based on these results, we suggest anesthetic-diluted IM PGB as the standard treatment for primary syphilis. TRIAL REGISTRATION: EudraCT 2014-003969-24 (Date of registration 18/09/2014).

Several physiologically-based pharmacokinetic (PBPK) models have been reported for intravenous (IV) and subcutaneous (SC) injections, but there has been a paucity of work for intramuscular (IM) injections. The primary objective of this work was a wide-scale evaluation of the predictive performance of IM PBPK models of therapeutic proteins. PBPK models for all administration routes available in the literature have regarded muscle as the total muscle (TM) in the body; however, anatomically, the body is composed of discrete muscle groups. Clinically, IM is administered to a specific muscle (SM). We explored the predictive performance of IM PBPK models with an SM or TM dosing site. The plasma concentration-time profiles of seven therapeutic proteins after an IM dose in humans served as the clinically observed data for model evaluation - this was a diverse group ranging from 30 to 149 kDa from six protein classes. Pharmacokinetic parameters Cmax, tmax, AUC0-∞, and ka were estimated. SM and TM IM PBPK approaches were compared using Average Fold Error (AFE) and Pearson Chi-Square LineShape analyses. This work represents the first wide-scale validation of IM PBPK models and suggests that these models predict IM PBPK reasonably well. The SM and TM approach provided comparable performance.

BACKGROUND: Intramuscular injections (IMIs) remain a frequent practice in mental health. Few studies have examined the issue of nurses' practices concerning IMI in this domain, and none considered specifically hygiene. Finally, no study appears to have looked at emergency situations and their possible influence on practices. The principal objective of our study was to assess the practices associated with IMI in mental health, especially the hygiene-related practices. The secondary objectives were as follows: 1) to assess the practices for the preparation and administration of IMI in mental health for criteria other than hygiene and 2) to determine whether professional experience and emergency situations influence these practices. DESIGN: Single-centre cross-sectional study in a psychiatric Hospital and adherence to the STROBE guidelines. METHODS: The participating nurses all worked with inpatients, and all volunteered for the study. A self-administered questionnaire was sent to all participants. The questionnaire included questions about knowledge and practices associated with IMI, some considered in two different situations: emergencies and planned injections. The distribution of the responses was tested by the chi-squared test or Fisher's exact test, as appropriate, or by McNemar's chi-squared test or Friedman's nonparametric chi-squared test for matched data. RESULTS: Response rate was 48.6%. Overall, 81% of nurses reported correct handwashing before preparation, 87.5% responded that the dorsogluteal site is currently recommended for IMI, and 74.6% that they did not know the "Z track" technique. In planned injections, 58.7% reported that the choice of needle was determined, at least in part, by the patient's body mass index. In emergency situations, adherence to guidelines was less frequent for all types of practices. CONCLUSIONS: This study shows the need to improve practices for the frequently used procedure of IMI among mental health nurses. RELEVANCE TO CLINICAL PRACTICE: Better professional education appears necessary to develop optimal practices, especially in emergency situations.

AIMS AND OBJECTIVES: This study aimed to determine the influences of gender, BMI and observed body shape on subcutaneous fat and muscle thicknesses, and theoretical injection outcome, at the ventrogluteal and dorsogluteal intramuscular injection sites. BACKGROUND: Debate continues as to whether the dorsogluteal or ventrogluteal injection site is more reliable for a successful intramuscular injection outcome. Subcutaneous fat and muscle thicknesses at the injection site are direct determinants of intramuscular injection outcome. BMI and observed body shape influence gluteal subcutaneous fat and muscle thicknesses, and therefore injection outcome, with potentially distinct effects at the ventrogluteal and dorsogluteal sites. DESIGN: This was a cross-sectional study. METHODS: Demographic data were collected, and subcutaneous fat and muscle thicknesses were quantified bilaterally at the dorsogluteal and ventrogluteal injection sites using ultrasound, for 145 participants (57% female). RESULTS: Subcutaneous fat and muscle were significantly thicker at the dorsogluteal than the ventrogluteal site, and 75% and 86% of participants would receive a successful intramuscular injection at these sites, respectively. There were significant effects of gender, BMI and observed body shape on subcutaneous fat thickness and theoretical injection outcome at both sites. Females, obese individuals and endomorph individuals had thicker subcutaneous fat and were more likely to have a subcutaneous injection outcome. CONCLUSIONS: Gender, BMI and observed body shape could be used to guide site and needle length selection when administering gluteal intramuscular injections to increase the likelihood of a successful intramuscular injection outcome. RELEVANCE TO CLINICAL PRACTICE: Both gluteal injection sites should be avoided in obese individuals and endomorph individuals. An intramuscular injection will be successful: using a 32-mm needle at the ventrogluteal site for all males and normal-weight females and using a 38-mm needle for all females at the ventrogluteal site, and for all males and at least 98% of females at the dorsogluteal site.

BACKGROUND: Gluteal muscle contracture (GMC), a debilitating disease, usually starts in early childhood after variable dose of injections around the buttock, if left untreated it worsens gradually and persists throughout the life. Because the disease mostly affects adolescents and adults, there is always an aesthetic concerns. Purposeof the study was to introduce the arthroscopic F and C method of GMC release, and to compare its clinical efficiency with conventional open surgery in terms of clinical outcome, rate of complications, patient's satisfactions, and recurrence. METHODS: Between Jan 2013 and July 2015, 75 patients received an arthroscopic release with F and C release method and 71 patients received conventional open release of GMC. Primary surgeries in 16 years or older patients were included in the study. Two groups were compared clinically using Hip Outcome Scores - Activities of Daily Living Subscale (HOS-ADL), Hip Outcome Scores - Sports Subscale (HOS-Sports), Visual Analogue Scale (VAS), and Ye et al. evaluation criteria. RESULTS: No statistically significant differences were observed in Hip Outcome Scores - Activities of Daily Living Subscale (HOS-ADL) (P = 0.078), Hip Outcome Scores - Sports Subscale (HOS-Sports) (P = 0.340), and Visual Analogue Scale (VAS) (P = 0.524) between the two groups. 74 (98.7%) patients in the arthroscopic surgery group had good to excellent results, whereas 69 (97.1%) patients in the conventional open surgery group had good to excellent results (P = 0.727). No statistically significant difference was observed in recurrence rate (P = 0.612). Statistically significant differences were observed in incision length, use of post-operative analgesia, post-operative off-bed activity, and hospital stay. Complications were significantly higher in the conventional open surgery group (n = 21) than in the arthroscopic surgery group (n = 10) (P = 0.016). More importantly, cosmetic satisfaction was 100% in arthroscopic release group, whereas only 71% had cosmetic satisfaction in conventional open surgery group (P < 0.001). CONCLUSION: Both, arthroscopic surgery and conventional open surgery, are highly effective tools for the GMC release in adolescent and adult patients. Arthroscopic GMC release with F and C method allows precise and selective release of contracture bands with small surgical trauma resulting fewer complications, high cosmetic satisfaction and minimal recurrence.

BACKGROUND: Although application of botulinum toxin type A (BTX-A) for the treatment of forehead rhytides has become very popular, the effects of its intramuscular injections on the skin mechanical properties remain unclear. OBJECTIVES: We prospectively investigated the alterations in the mechanical properties of the skin of patients who received intramuscular injections of botulinum toxin A (BTX-A) for forehead rhytides and compared two injection doses. METHODS: Of the 42 enrolled patients, one randomly assigned half received intramuscular injections of two units (group I), and the other half received four units (group II) of BTX-A in each injection point. The baseline and post-treatment skin mechanical parameters, including gross elasticity (R2), net elasticity (R5), viscoelastic ratio (R6) and biological elasticity (R7), were measured using the Cutometer(®) and compared. RESULTS: Treatment with BTX-A resulted in significant overall alterations in the mechanical properties of skin at the injection sites of both treatment groups during the 16-week period, and no significant differences were observed between groups. Significant decreases in biological elasticity, net elasticity and viscoelasticity properties were observed at 2 weeks follow-up and began to recover at that time. All of the skin mechanical properties recovered to baseline levels by 16 weeks of follow-up in both dosage groups, which indicates that the higher dosage (4 units) did not delay relapse compared to the two-unit dosage. CONCLUSIONS: We concluded that intramuscular injections of BTX-A significantly regulated the gross elasticity, net elasticity, functional elasticity and viscoelastic elasticity at the injection point over a radius of 1.5 cm at 2, 4 and 8 weeks follow-up. The alteration in the skin measurements had completely diminished by the 16-week follow-up. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

AIMS AND OBJECTIVES: To review the available evidence on aspirating when administering intramuscular injections and suggest recommendations for practice. BACKGROUND: The process of aspiration has been ingrained in the intramuscular injection procedure, and whilst many policies no longer recommend this practice, it often continues to be taught and practiced. The result is a variation in this procedure not always consistent with an evidence-based approach. DESIGN: A systematic literature review. METHODS: A systematic approach to searching the literature was undertaken using identified academic databases from inception to May 2014. Citation searching identified additional data sources. Six studies met the search criteria. RESULTS: The majority of health professionals do not aspirate for the recommended 5-10 seconds. Administering an injection faster without aspiration is less painful than injecting slowly and aspirating. The main influences on the decision of whether or not to aspirate are based on what health professionals are taught and fear of injecting into a blood vessel. CONCLUSIONS: In the paediatric vaccination setting, the practice of aspirating during the administration of an intramuscular injection is unnecessary and there is no clinical reason to suggest that these principles may not be applied when using the deltoid, ventrogluteal and vastus lateralis sites in other settings. Owing to its proximity to the gluteal artery, aspiration when using the dorsogluteal site is recommended. Nurses must be supported in all settings, by clear guidance which rejects traditional practice and facilitates evidence-based practice. RELEVANCE TO CLINICAL PRACTICE: Educators need to ensure that their knowledge is up to date so that what they teach is based on evidence. This may be facilitated via regular educational updates. Further research and subsequent guidance are needed to support evidence-based practice in intramuscular injection techniques in all nursing settings.

Identification of safe injections sites is a skill practised routinely by nurses, which, as with all nursing practice, is informed by empirical evidence. Despite this, discussion as to whether the dorsogluteal site should be eradicated from nursing practice in favour of the ventrogluteal site shows no sign of abating. Review of commonly cited evidence in this debate aimed to identify the validity of excluding the dorsogluteal site in favour of the ventrogluteal site by investigating the empirical evidence, which routinely informs this decision. Empirical evidence suggests a case to exclude the dorsogluteal site for children under age 10 for fear of damaging the sciatic nerve, but not so for adults. Recommendations are made for conclusive research into the viability of the dorsogluteal site and an authoritative decision based on empirical evidence, not hearsay, with regard to its continuance or eradication from nursing practice.

AIMS AND OBJECTIVES: To consider to what extent intramuscular injection technique can be described to remain entrenched in ritualistic practice and how evidence-based practice should be considered and applied to the nursing practice of this essential skill. BACKGROUND: The notion of rituals within nursing and the value or futile impact they afford to this essential nursing skill will be critically reviewed. DESIGN: Discursive paper. METHOD: Literature review from 2002-2013 to review the current position of intramuscular injection injections. RESULTS: Within the literature review, it became clear that there are several actions within the administration of an intramuscular injection that could be perceived as ritualistic and require consideration for contemporary nursing practice. CONCLUSIONS: The essential nursing skill of intramuscular injection often appears to fit into the description of a ritualised practice. By providing evidence-based care, nurses will find themselves empowered to make informed decisions based on clinical need and using their clinical judgement. RELEVANCE TO CLINICAL PRACTICE: For key learning, it will outline with rationale how site selection, needle selection, insertion technique and aspiration can be cited as examples of routinised or ritualistic practice and why these should be rejected in favour of an evidence-based approach. The effect on some student nurses of experiencing differing practices between what is taught at university and what is often seen in clinical practice will also be discussed.

OBJECTIVE: To compare the efficacy and safety of ketamine alone with those of ketamine-dexmedetomidine combination for sedation during brain CT in paediatric patients with head injuries. METHODS: We retrospectively analysed the data of paediatric patients who underwent sedation for brain CT at the ED. We included patients aged 6 months to 6 years with American Society of Anesthesiologists physical status I or II. The sedative protocol involved the administration of intramuscular (IM) ketamine 3 mg/kg (K), ketamine 2 mg/kg with dexmedetomidine 1.5 µg/kg (KD) or ketamine 1.5 mg/kg with dexmedetomidine 1.5 µg/kg (low-KD). The primary and secondary outcomes were sedation failure and adverse events, respectively. RESULTS: We included 77 patients; among them, 28, 23 and 26 were in the K, KD and low-KD groups, respectively. In multivariable analysis, the combination groups (KD and low-KD groups) were significantly associated with a lower possibility of sedation failure compared to the K group (adjusted odds ratio, 0.12; 95% confidence interval, 0.02-0.56). Moreover, there were no significant differences in adverse events between the groups, and the sedation-related time variables also did not significantly differ among the three groups. CONCLUSIONS: Our findings indicated that a combination of IM ketamine-dexmedetomidine provides effective sedation for paediatric patients undergoing brain CT without significant adverse events. Further research is needed to investigate the potential benefits of using lower doses of ketamine in combination.

Cabotegravir (CAB) and rilpivirine (RPV) is the first complete long-acting (LA) injectable regimen recommended by treatment guidelines for the maintenance of HIV-1 virologic suppression in people with HIV-1 who are virologically suppressed on a stable antiretroviral regimen that is administered monthly (Q1M) or every 2 months (Q2M). As an alternative regimen to lifelong daily oral antiretroviral therapy, Q1M or Q2M dosing schedules are associated with increased patient satisfaction and treatment preference. In addition, it may address challenges associated with daily oral dosing, including fear of treatment disclosure or stigma, anxiety related to oral dosing adherence, and the daily reminder of HIV disease status. Cabotegravir + RPV LA is administered by clinical staff as two intramuscular injections dosed Q1M or Q2M. In this review, we share practical dosing guidance for CAB+RPV LA injectable therapy, including how to initiate therapy, schedule injection visits, manage dosing interruptions due to missed or delayed injection visits, manage errors in dosing, and transition to alternative antiretroviral therapy after discontinuation. Practical guidance on the clinical management of CAB+RPV LA dosing, including a detailed discussion using case-based scenarios that may be encountered in clinical practice, is provided. The clinician-administered CAB+RPV LA regimen has dosing management considerations that are flexible and considerate of the patient and has the potential to provide a highly desirable and efficacious alternative to daily oral antiretroviral therapy for many people with HIV-1.
Guidance for clinicians on the management of long-acting Cabotegravir and Rilpivirine Injectable Therapy for HIV-1 Cabotegravir (CAB) and rilpivirine (RPV) is the first long-acting (LA) injectable therapy for people with HIV-1 who previously achieved undetectable virus levels using other HIV-1 medications. People with HIV-1 receive CAB+RPV LA as two injections given by their clinician every 1 month or every 2 months, providing an alternative treatment option to lifelong daily oral medications. People with HIV-1 receiving CAB+RPV LA every 1 or 2 months have higher levels of treatment satisfaction and often prefer CAB+RPV LA compared with daily oral medications. Cabotegravir+RPV LA may also address challenges associated with daily oral medications, including fear of inadvertently sharing HIV status, anxiety related to taking daily medications, and having a daily reminder of HIV. In this review, we provide guidance for clinicians on how to administer CAB+RPV LA injectable therapy, including how to start patients on CAB+RPV LA injections, schedule injection visits, manage missed or delayed injection visits, manage dosing errors, and switch patients to a different treatment if CAB+RPV LA is discontinued. This review also includes a detailed discussion of potential scenarios related to the administration and scheduling of CAB+RPV LA injections that may occur in clinical practice. Overall, this review serves as a practical guide for managing CAB+RPV LA injectable therapy in clinical practice that will be useful for HIV clinicians.
RESUMEN
A 61-year-old woman presented to the emergency ward complaining of low back pain for a month. She had undergone several spinal surgeries and a right radical nephrectomy 30 years before. A few days earlier she was injected with an intramuscular painkiller in her right buttock. An abdominal CT scan revealed multiple abscesses in the psoas muscle and the right posterior abdominal wall, including cellulitis in the adjacent subcutaneous tissue and the injection site. A diagnosis of pyomyositis from subcutaneous dissemination was made, and intravenous cefazolin was initiated. After five days of favorable progress, treatment was switched to oral cefadroxil to complete four weeks, leading to full recovery.
RESUMEN
The gluteal region is a frequent target for injecting high volumes. However, the safe intramuscular injection sites have been controversy in this region. This study was aimed to compare the subcutaneous fat and muscle thicknesses at the two gluteal injection sites and to determine the influence of sex and body mass index (BMI) on fat and muscle thicknesses. The ultimate purpose of this study is to suggest the most suitable intramuscular injection site among the ventrogluteal and dorsogluteal regions. Eleven fresh cadavers were injected with colored gelatin using syringes at the two gluteal injection sites. Seven variables were measured at both gluteal injection sites and analyzed relative to sex and the BMI. No variables showed statistically significant differences between the two gluteal injection sites according to sex. In a one-way analysis of variance, total length and muscle thickness had significant difference according to the BMI category. In obese cadavers, the injected gelatin core was located in the subcutaneous layer (average 109.0 percentile), and in the muscle layer (average 78.9 percentile) in the dorsogluteal region. These were found that the success rate of injection in the dorsogluteal region was higher than in the ventrogluteal region, especially when classed as obese. Also, it is suggested that nurses should use the traditional intramuscular injection method. It will also be necessary to consider expanding these findings to other ethnic groups in the Asia-Pacific region and then also education in universities and health providers on selecting the intramuscular gluteal injection site.
RESUMEN
PURPOSE: A case of embolia cutis medicamentosa (Nicolau syndrome) in a patient receiving monthly intramuscular fulvestrant injections is presented. SUMMARY: An 85-year-old woman receiving monthly fulvestrant injections in the outpatient setting developed a necrotic lesion at the fulvestrant injection site on her right buttock. Her medical history is notable for metastatic breast cancer with bone metastases. Prior to developing the necrotic lesion, the patient was receiving monthly fulvestrant injections for 6 years. Other potential causes such as infection and pressure necrosis were ruled out clinically. After 185 days of wound care involving multiple surgical debridements, topical therapy, and frequent follow-up appointments, the patient's wound resolved with 100% epithelialization. Nicolau syndrome has been reported with other non-vesicant, injectable medications such as antibiotics and corticosteroids; however, it has not been previously reported with fulvestrant. CONCLUSION: Nicolau syndrome developed in the right buttock of a patient with metastatic breast cancer following an intramuscular fulvestrant injection. Healthcare practitioners need to be cognizant of this adverse effect with intramuscular injections in order to recognize and refer patients for wound care evaluation early in the evolution of this syndrome. Proper injection technique is recommended to reduce the risk of this idiopathic adverse effect.
