High- and low-pressure vacuum drains are commonly used after surgical procedures. High-pressure vacuum drains (ie, sealed, closed-circuit systems) are efficient and allow for easy monitoring and safe disposal of the drainage. Low-pressure vacuum drains use gentle pressure to evacuate excess fluid and air, and are easy for patients to manage at home because it is easy to reinstate the vacuum pressure. Perioperative nurses should be able to identify the various types of commonly used drains and their surgical applications. Nurses should know how to care for drains, how to reinstate the vacuum pressure when necessary, and the potential complications that could result from surgical drain use.
手术操作后通常会使用高压和低压真空引流装置。高压真空引流装置（即密封的闭路系统）效率高，便于监测引流液并安全处理。低压真空引流装置利用轻柔压力排出多余的液体和空气，患者在家中易于操作，因为恢复真空压力很容易。围手术期护士应能够识别各种常用的引流装置及其手术应用。护士应知道如何护理引流装置，如何在必要时恢复真空压力，以及使用手术引流装置可能导致的潜在并发症。
