To examine depth of subcutaneous fat at gluteal intramuscular injection sites.
Retrospective study.
General hospital.
100 consecutive adults who had computed tomography of the pelvis.
Minimum distance between the surface of the skin and the nearest edge of muscle at intramuscular injection sites.
12 patients had a ventrogluteal site depth of more than 35 mm, the maximum depth of a green needle, and 26 had a ventrogluteal depth of more than 25 mm, the maximum depth of a blue needle. 43 patients had a dorsogluteal site depth of more than 35 mm, and 72 had a dorsogluteal depth of more than 25 mm. The intramuscular site was likely to be deeper in women.
Standard green and blue needles do not reach the gluteal muscles in a considerable number of patients.
检查臀肌内注射部位皮下脂肪的深度。
回顾性研究。
综合医院。
100名连续接受骨盆计算机断层扫描的成年人。
肌肉注射部位皮肤表面与肌肉最近边缘之间的最小距离。
12例患者的臀中肌注射部位深度超过35毫米（绿色针头的最大深度），26例患者的臀中肌深度超过25毫米（蓝色针头的最大深度）。43例患者的臀大肌注射部位深度超过35毫米，72例患者的臀大肌深度超过25毫米。肌肉注射部位在女性中可能更深。
相当数量的患者使用标准的绿色和蓝色针头无法到达臀肌。
