— Explanation · 中文詳解 —
嗎啡(Morphine)作為中樞神經系統抑制劑,其最主要的致命副作用為呼吸抑制。在使用靜脈止痛幫浦(Patient-Controlled Analgesia, PCA)時,由於藥物直接進入血液循環,必須優先監測呼吸頻率與深度,以確保病人不會因藥物過量而導致呼吸衰竭。呼吸頻率下降往往是呼吸抑制的早期徵兆,故為護理評估之首要項目。
Respiratory depression is the most serious and potentially fatal side effect of morphine. Therefore, monitoring respiratory rate and depth is the highest priority assessment to detect early signs of overdose or respiratory failure.
