We describe a study made at two pediatric centers to test experimental lancets for blood collection by skin puncture of infants' heels or fingers. Our primary goal is to decrease the hazard of osseous injury while collecting adequate blood, by using three lancet widths at a constant length of 1.0 mm. The three widths used were 1.0, 1.25, and 1.5 mm. When success at skin puncture was defined rigidly on the basis of the blood volume obtained, the data show that success was related neither to the lancets' dimensions as tested nor to the age of the child, but rather to the phlebotomist's skill and experience, which improved with time.
我们描述了在两个儿科中心进行的一项研究，以测试用于通过穿刺婴儿足跟或手指皮肤来采集血液的实验性采血针。我们的主要目标是在采集足够血液的同时降低骨损伤风险，方法是使用长度恒定为1.0毫米的三种采血针宽度。所使用的三种宽度分别为1.0、1.25和1.5毫米。当根据获得的血量严格定义皮肤穿刺成功时，数据表明成功既与所测试的采血针尺寸无关，也与儿童年龄无关，而是与采血技师的技能和经验有关，而技能和经验会随着时间得到提高。
