Ultrasound-Guided Assessment of Ventrogluteal Intramuscular Injection in Adults With High BMI

Sponsor: Marmara University

View on ClinicalTrials.gov

Summary

This study evaluated the ventrogluteal site for intramuscular injection in adults with a body mass index of 25 kg/m² or higher. Ultrasound was used to measure subcutaneous tissue, muscle, and total tissue thickness at the injection site and the distances from the injection point to anatomical landmarks and the sciatic nerve. During intramuscular injection with a 40 mm needle, real-time ultrasound was used to visualize the needle tip and assess its position within the muscle. The study also evaluated successful intramuscular placement, subcutaneous medication leakage, and injection-related complications. The findings were assessed across three body mass index groups.

PROCEDURE

Ventrogluteal Intramuscular Injection Using a 40 mm Needle

Participants received a ventrogluteal intramuscular injection of 1 mL cyanocobalamin (1000 mcg/mL) using a 40 mm, 21-gauge needle. The injection site was identified using the G method. During the injection, the needle tip was visualized in real time using ultrasonography to evaluate its intramuscular position, including its distance from the superficial muscle fascia and the ilium. The position of the needle tip relative to the sciatic nerve was also assessed.
