Comparison of the G and V methods for ventrogluteal site identification: Muscle and subcutaneous fat thicknesses and considerations for successful intramuscular injection

The ventrogluteal site is increasingly recommended for long‐acting antipsychotic intramuscular injections; however, it remains infrequently utilized due to nurses’ lack of confidence in site identification. The more recent G (geometric) method of ventrogluteal site identification is less subjective and likely more reliable than the V method for successful intramuscular injection outcomes. Knowledge of muscle and subcutaneous fat thicknesses, and...
