Explanation · 中文詳解

Z 軌跡技術(Z-track technique)是一種特殊的肌肉注射方法,主要用於注射對皮下組織具有刺激性、可能導致皮膚變色(如鐵劑)或吸收不良的藥物。這種技術透過物理方式,在注射後將藥物「鎖定」在肌肉深層,防止其回滲到較淺的皮下組織中。正確執行 Z 軌跡技術對於減少病人不適、預防藥物引起的局部反應和確保藥物療效至關重要。

The Z-track technique displaces the skin and subcutaneous tissue before injection, creating a zigzag path that seals the medication within the muscle upon withdrawal. This prevents irritating substances from leaking into the subcutaneous tissue, reducing skin discoloration and tissue damage.
