護理師照護一名全髖關節置換術後的病人，哪項介入措施最能有效預防深部靜脈栓塞？
A nurse is caring for a client who is post-operative following a total hip arthroplasty. Which intervention is most effective in preventing deep vein thrombosis?
- AMaintaining strict bed rest for 48 hours嚴格卧床休息 48 小時
- BPlacing a pillow under the knees for comfort在膝蓋下放置枕頭以增加舒適度
- CApplying sequential compression devices (SCDs)✓ 正解應用連續性氣壓裝置 (SCDs)
- DRestricting fluid intake to decrease venous pressure限制液體攝取以降低靜脈壓力
— Explanation · 中文詳解 —
全髖關節置換術後病人血栓風險高。SCD 能透過機械性擠壓促進下肢血液回流，減少靜脈淤滯。長期臥床反而增加血栓風險；膝下墊枕會壓迫膕窩血管，阻礙血液循環；補充足夠水分有助於降低血液黏稠度，而非限制飲水。
Sequential compression devices (SCDs) are the most effective intervention for preventing deep vein thrombosis in post-operative hip arthroplasty clients because they mechanically promote venous return and reduce stasis. Prolonged bed rest increases clot risk, placing pillows under the knees restricts blood flow, and restricting fluids can lead to hyperviscosity rather than preventing clots.
✦ 台美臨床差異
美國醫院廣泛落實早期下床與機械性預防；台灣病患術後常有較長的臥床期，需加強衛教。
