This study was designed to determine whether the success rate in establishing intraosseous infusion (IOI) varied with four different types of needles--standard hypodermic, spinal, bone marrow, and Turkel intraosseous infusion needle. Twenty-four second-year residents from various specialties, without prior training or experience in the technique, participated in the study. Each participant attempted to establish an intraosseous infusion in a randomly assigned limb of an anesthetized piglet, using each needle in a randomly assigned order. The overall success rate was 67.7%. Success ratios varied between needles: hypodermic 54%, spinal 75%, bone marrow 75%, and Turkel 67%. Utilizing Cochran's Q-test, there was no statistical difference in success rates between needle types. However, in cases where the resident was successful with all four needles, the average time to successful infusion was significantly less for bone marrow needles.
本研究旨在确定使用四种不同类型的针头——标准皮下注射针、脊椎穿刺针、骨髓穿刺针和Turkel骨内输液针——建立骨内输液（IOI）的成功率是否存在差异。来自各个专业的24名二年级住院医师，此前未接受过该技术的培训或有相关经验，参与了这项研究。每位参与者尝试在一只麻醉小猪的随机分配的肢体上建立骨内输液，按照随机分配的顺序使用每种针头。总体成功率为67.7%。不同针头的成功率有所不同：皮下注射针为54%，脊椎穿刺针为75%，骨髓穿刺针为75%，Turkel针为67%。使用 Cochr an Q检验，不同类型针头的成功率之间没有统计学差异。然而，在住院医师使用所有四种针头均成功的情况下，骨髓穿刺针成功输液的平均时间明显更短。
