Subjects were 40 adult subjects diagnosed with schizophrenia and treated with LAI [32 patients were risperidone LAI (RLAI) and 8 patients were aripiprazole LAI (ALAI)]. However, in this paper, only three cases (one RLAI case and 2 ALAI cases) were selected to illustrate the diffusion effects of both LAI. Dorsogluteal intramuscular (IM) injection sites were measured at prone position using the “double cross” method. Before LAI injection, the distance from the epidermis to the under-fascia (DEUF), and distance from the epidermis to the iliac bone (DEI) at the IM injection site were assessed by using ultrasonography: 1) the injection needle was inserted to the gluteus medius, and 2) observed the diffusion status within the muscle injected RLAI and ALAI were confirmed using the B-mode ultrasonography. Both RLAI and ALAI were depicted as high echogenicity with acoustic shadowing. It was considered that the diffusion states of LAIs by ultrasonography were important time course evaluations providing objective evidence.展开更多

The suggested site is the gluteal muscle with a needle length of two inches (50 mm) in Japan, which is longer than the ordinarily used needle for intramuscular injections. The aim of this study was to determine the optimal needle insertion length for accurate delivery of RLAI procedure among subjects who have normal body mass index (BMI: 18 to 25) and high BMI (>25). Thirty-seven patients with schizophrenia were administered RLAI intramuscularly into the dorsogluteal muscle. The standard procedure required inserting 80% of the two inch needle. By using data collected by ultrasonography, the findings confirmed that the median needle insertion lengths for subjects with normal and high BMI were 39.0 and 45.5 mm, respectively. To deliver RLAI effectively and safely, the authors strongly recommend that a specialized needle be used that is “marked” at the 40 mm point from the tip of the needle to the base. In this way regardless of subcutaneous fat content, the RLAI can be safely delivered into the muscle without causing untoward or side effects.展开更多

However, if needle insertion depth is deeper than anticipated, needle penetration may cause damage to nerves, arteries and veins. Few clinical studies were done to evaluate the depth of needle length insertion reaching the intended gluteal muscle. The aim of this study was to evaluate the suitable depth of injecting RLAI. Twenty-six patients with schizophrenia were treated with RLAI, and randomly divided into two groups: 50 mm needle inserted group (Group-D, deep insertion, n = 13) and 20 mm needle insertion group (Group-S, shallow insertion, n = 13). For Group-S, the needle length was marked with a spacer at exactly 20 mm. Injections were performed by the psychiatrist or nurse, alternating between the two gluteal sites by double-cross method every two weeks. Clinical psychotic symptoms and injection site reactions were recorded throughout the study period. Experienced psychologists who were blinded from the needle-length experimental variable evaluated patients’ psychotic symptoms using the Positive and Negative Syndrome Scale (PANSS) every two weeks. The plasma 9-hydroxyrisperidone (9-OH-RIS) concentrations were measured every two weeks;comparison data were determined on the 8th week and the 14th week. No significant difference was observed in 9-OH-RIS concentrations, psychotic symptoms, injection site skin reactions of subjects in both groups. However, in Group-D, injection site adverse reactions were confirmed in two subjects (15%). In Group-S, injection site reactions were confirmed in six subjects (46%). Although effective 9-OH-RIS concentrations were obtained with the insertion using both depth, it was concluded that the 50 mm insertion length was more suitable for dorsogluteal IM injections in adult patients with schizophrenia as demonstrated by the incidence of local adverse skin reactions.展开更多

Achieving maximum effects of medications through precise intramuscular (IM) injections must be assured and with certainty, particularly with long-acting injection drugs (LAI). The purpose of this study is to determine precision in IM LAIs of patients with schizophrenia. These evidences estimate “Distance from the Epidermis to the Under-Fascia” (DEUF) and “Distance from Epidermis to the Upper-Arm Bone” (DEB) of the deltoid muscle. Explanatory variables include body height, weight, body-mass index (BMI), deltoid-muscle circumference, fat percentage and muscle mass measured by body composition monitor. Sixty nine subjects are included based on the Diagnostic Statistical Manual of Mental Disorders (DSM-IV, 1994), and receive treatments of typical and atypical antipsychotic LAI. There are 46 males and 23 females with average age of 51.41 (Standard Deviation = 13.58) and ranging from 21 to 81 years who are all right-handed. Ultrasonographic data and those from explanatory variables are calculated using Spearman’s rank correlation coefficients. Multiple regression analysis (step-wise method/forced input method) is performed assuming DEUF or DEB as dependent variables. Significant correlations are found with highest adjusted R-square. Paired t-tests show differences in average values of actual ultrasonographic measurements assigned to DEUF or DEB, and the regression equations for accuracy. Ultrasonographic values are assigned multiple-regression equations as true values, and the calculated values are compared with those obtained by regression equations. There are no significant differences observed for either the right or left arm. The multiple regression equations for BMI and fat percentages (upper extremity estimation) of DEUF, and for BMI and injection site circumference of estimated DEB, successfully value the DEUF and DEB. By using these multiple regression equations for IM injection to the deltoid-muscle, DEUF can better ensure accurate LAI into the muscle through body monitor, DEB, and measured values of the deltoid-muscle injection site circumference.展开更多
