A study on safe intramuscular injection skills by evidence-based nursing

目的：1.目的：1.评价肌内注射部位皮下组织厚度测量仪的临床应用价值.评估肌肉注射安全部位的位置方法：半结构式访谈和观察实际肌肉注射的护士在医院。获得的知识，从专家的解剖和观察肌肉注射部位。结果和讨论：根据我们对肌肉注射皮下组织厚度的回归公式的研究结果，我们制作了一种用游标卡尺测量皮下组织厚度的评估仪器。使用我们的评估仪器对37名受试者进行了测量，测量结果与超声测量结果几乎相同。然而，在肥胖患者中使用评估仪器时，由于护士的操作方式不同，也会出现错误。护士们表示：“我们想使用评估仪器，因为我们是循证护理，但是很难知道应该施加多大的压力。“我们需要在评估皮下组织时力求准确。护士在确定肌肉注射所需的针头长度时需要评估皮下组织厚度。我们需要评估皮下组织以开发此工具。我们从解剖学专家那里获得了知识，并观察了肌肉注射部位的静脉和神经。

Purpose :1. To assess the clinical application of an assessment instrument to measure subcutaneous tissue thickness at the site of intramuscular injection.2. To assess the location of safe sites for intramuscular injectionMethod :Semi-structured interviews and observation of actual intramuscular injections by nurses in hospitals.Obtainment of knowledge from a specialist of anatomy and observation of the site of intramuscular injection.Result and Discussion :We made an assessment instrument to measure subcutaneous tissue thickness from vernier calipers based on the results of our study using regression formulae to assess subcutaneous tissue thickness for intramuscular injection.Measurements obtained from 37 subjects using our assessment instrument were nearly equal to those obtained by ultrasonography.However, errors occurred when using the assessment instrument in the case of fat subjects and depending on how the nurses held the instrument.Nurses reported, "We want to use the assessment instrument because of evidence-based nursing, but it is difficult to know how much pressure to apply."We need to strive for accuracy in assessment of subcutaneous tissue.Nurses need to assess subcutaneous tissue thickness when determining needle length required for intramuscular injection.We need to assess subcutaneous tissue for the development of this toolWe obtained knowledge from a specialist of anatomy and observed veins and nerves at the site of intramuscular injection.
