護理師正在照護一位放置傑克森-普拉特（Jackson-Pratt）引流管的術後病人。下列哪項護理措施對確保引流裝置功能正常最為關鍵？
A nurse is caring for a postoperative client who has a portable wound suction device (Jackson-Pratt). Which nursing action is most critical to ensure the device functions correctly?
- ASecure the drainage tubing to the client's skin with sutures以縫線將引流管固定於病人皮膚上
- BEnsure the bulb is compressed and the cap is closed tightly✓ 正解確保引流球處於壓縮狀態且瓶蓋緊閉
- CClean the insertion site with hydrogen peroxide daily每日以雙氧水清潔插入部位
- DEmpty the reservoir every 8 hours regardless of volume無論容量多少，每 8 小時排空儲液槽
閉鎖式引流裝置（如 Jackson-Pratt）運作的核心在於維持負壓抽吸，移除傷口死腔內的滲液並促進組織癒合。這類裝置必須在排空液體後，將引流球擠壓（compress）使空氣排出，然後迅速蓋上蓋子鎖緊，才能創造持續的負壓環境。若瓶蓋未密封，空氣進入會導致負壓喪失，引流將完全失效，不僅無法減少傷口腫脹，還可能增加細菌逆行性感染的風險。護理師在每次清空引流液後，務必重新檢查負壓狀態是否維持，這不僅是機械運作的必要條件，更是減少術後感染與併發症最重要的防範措施。
Closed-suction wound drains (e.g., Jackson-Pratt) function by maintaining negative pressure to remove fluid from dead space and promote healing. After emptying, the bulb must be compressed to expel air and the cap quickly tightened to create continuous suction. If the cap is not sealed, air entry causes loss of negative pressure and drainage failure, increasing the risk of retrograde bacterial infection. The nurse must recheck the negative pressure after each emptying; this is essential not only mechanically but also to prevent postoperative infection and complications.
美國護理指引高度強調引流液性質與量的變化趨勢記錄（I&O），台灣臨床則常將引流管照護納入常規換藥程序，對於引流液顏色改變的判斷標準（如從漿液性變為鮮紅色），美國護理師常具備更明確的臨床判斷授權直接通知醫師。
