Explanation · 中文詳解

氯化鉀具有高度刺激性,一旦發生靜脈炎或外滲(extravasation),必須立即停止輸注以防組織壞死。此為高警訊藥物(High-Alert Medication),任何滲漏都需採取保護組織的緊急應變,並考慮後續是否有解毒劑或熱敷/冷敷的指引,但首要動作永遠是中斷給藥。

KCl is highly irritating; phlebitis or extravasation requires immediate cessation of infusion to prevent tissue necrosis. As a high-alert medication, any extravasation requires urgent tissue-protective action and consideration of facility-specific antidote or compress guidelines — but the first action is always to stop the infusion.

✦ 台美臨床差異

美國護理師依據 PIV 外滲分級處理(如熱敷或特殊解毒劑),台灣臨床更強調移除管路並請醫師評估,對於高濃度鉀離子滲漏會特別警覺。
