ABSTRACT: Long Acting Injectable (LAI)
medications for patients with schizophrenia is commonly administered to relieve
their symptoms. Through shared decision-making and clinical evidence-based, psychiatrists
should systematically offer LAIs to all patients requiring long-term
antipsychotic treatment as a first-line treatment. Gluteal intramuscular (IM)
injection requires accurate insertion of needles into the specific muscle area,
often the outer upper quadrant of the buttocks, in order to achieve the
required blood concentration. The purposes of this study were to compare the
“Distance from the Epidermis to the Under-Fascia (DEUF)” and “Distance from the
Epidermis to the Iliac Bone (DEB)” of the buttocks IM injection sites at the
dorsogluteal and ventrogluteal sites among healthy Japanese volunteer subjects,
and to identify the optimal insertion injection needle length. The DEUF and DEB
at the gluteal regions were measured by ultrasonography. Welch’s one-way
analysis of variance was used to compare the DEUF and the DEB at the gluteal IM
injection regions. There was no statistically significant difference observed
between the right and left mean values of DEUF for Hochstetter and Clark’s
point at the ventrogluteal sites, and the Four and Three-way split or Double
Cross point at the dorsogluteal sites. However in the DEB, the Hochstetter’s
point (P
