Tourniquet use during extremity surgery is commonplace and a relatively safe practice. The surgical team's knowledge of the patient history, proper assessment, and indications and contraindications for and risks of tourniquet use can prevent unwanted outcomes. Exploration of these critical areas reinforces perioperative nurses' awareness and understanding of safe tourniquet use. Additionally, a review of the physiological effect of tourniquets on the skin, the body's response to local compression, the risk of vascular compromise, and the effect of the tourniquet on postoperative pain and swelling provides insight into AORN recommended practice guidelines. This article summarizes the indications and assessments for and risks of tourniquet use for patients during extremity surgery. An understanding of these topics can improve surgical outcomes and promote safe perioperative care.
在肢体手术中使用止血带很常见，且是一种相对安全的做法。手术团队对患者病史的了解、恰当的评估以及止血带使用的适应证、禁忌证和风险，能够预防不良后果。对这些关键领域的探究强化了围手术期护士对安全使用止血带的认识和理解。此外，回顾止血带对皮肤的生理影响、身体对局部压迫的反应、血管受损的风险以及止血带对术后疼痛和肿胀的影响，有助于深入了解美国手术室注册护士协会（AORN）推荐的实践指南。本文总结了肢体手术患者使用止血带的适应证、评估及风险。了解这些主题可改善手术效果并促进安全的围手术期护理。
