简要总结
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.

研究组 & 干预措施
Ventrogluteal Intramuscular Injection
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 using real-time ultrasonography to assess its intramuscular position and its distances from relevant anatomical structures.

结局指标
主要结局
Percentage of Participants With Successful Intramuscular Placement of the 40 mm Needle
时间窗: During the injection procedure, immediately after full insertion of the needle and before medication administration
The percentage of participants in whom the 40 mm needle met the predefined intramuscular placement criteria was assessed using real-time ultrasonography. Successful intramuscular placement was defined as the needle tip being at least 10 mm beneath the superficial muscle fascia and at least 10 mm away from the iliac cortex.
