【摘要】 目的:为婴幼儿肌内注射最佳部位的选择提供解剖学资料。方法:对20具婴幼儿尸体标本和4套幼儿断层标本的臀区、股外侧区和三角肌区的血管神经走行和毗邻关系进行解剖观察,测量各区皮肤、浅筋膜和肌的厚度。结果:臀区外上部的皮肤和浅筋膜厚(0.86±0.23)cm,肌厚(1.65±0.30)cm;股外侧区中部皮肤、浅筋膜厚(0.64±0.28)cm,肌厚(1.29±0.18)cm;三角肌区中部皮肤、浅筋膜厚(0.65±0.11)cm,肌厚(0.74±0.12)cm。以上各部肌质较厚,无重要血管神经。结论:从安全角度考虑,婴幼儿肌内注射以股外侧区中部作为首选部位为宜,次选臀区。更多还原

【Abstract】 Objective:To provide anatomic data for choosing optimal sites of intramuscular injection in infants.Methods:To observe the courser and adjacent relationship of the vascular nerve in gluteal region, vastus lateralis region and deltoid region on 20 infant corpses and 4 fault specimens. The thickness of skin-superficial fascia and muscles in various regions were measured respectively.Results:The thickness of skin-superficial fascia and muscles were (0.86±0.23)cm and (1.65±0.30)cm in medial-superior quadrant of gluteus region, (0.64±0.28) cm and (1.29±0.18) cm in central section of vastus lateralis region,(0.65±0.11)cm and (0.74±0.12)cm in middle section of deltoid region, respectively. Within above mentioned sections, the thickness of muscle was more generous, and without any important vascular nerve passing.Conclusion:Considering safety,the optimal site of intramuscular injection in infants locates at the central section of vastus lateralis region and the following site belongs to gluteal region.更多还原
