A single-needle single-site technique for bone marrow aspiration and core biopsy has been compared with a two-needle technique, using 30 randomly selected patients who required these two investigations. In addition, two single-needle techniques were compared, aspirating immediately after penetrating the cortex or, alternatively, aspirating after the needle (without the stilette) had been advanced 20-25 mm. The two-needle technique was found to be superior to either of the single-needle techniques, which often resulted in a biopsy specimen that was denuded of bone marrow cells.
采用单针单点技术进行骨髓穿刺和核心活检,并与双针技术进行了比较,研究选取了30名随机挑选的需要这两项检查的患者。此外,还比较了两种单针技术,一种是在穿透皮质后立即抽吸,另一种是在针(不带针芯)推进20 - 25毫米后抽吸。结果发现,双针技术优于任何一种单针技术,单针技术常常导致活检标本骨髓细胞缺失。
