Continuous-flow cryotherapy units have been proved to decrease pain, inflammation, swelling, blood loss, and narcotic usage in the postoperative setting. Complications related to cryotherapy are extremely rare (estimated at 0.00225%) but can be devastating. Complications include frostbite, chronic pain, and loss of digits. Caution should be exercised when prescribing continuous-flow cryotherapy units to patients with known risk factors for cold injury. All members involved with care of the patient, including the physician, nursing staff, patient, and patient's family and caregivers, should take an active roll in monitoring the foot for signs and symptoms of cold injury. Continuous-flow cold therapy should be discontinued when capillary refill time is greater than 5 seconds.
连续流式冷冻治疗设备已被证明可在术后减少疼痛、炎症、肿胀、失血和麻醉药物的使用。与冷冻治疗相关的并发症极为罕见（估计为0.00225%），但可能是毁灭性的。并发症包括冻伤、慢性疼痛和手指缺失。对于已知有冷损伤风险因素的患者，在开具连续流式冷冻治疗设备处方时应谨慎。所有参与患者护理的人员，包括医生、护理人员、患者及其家属和护理人员，都应积极参与监测足部是否有冷损伤的迹象和症状。当毛细血管再充盈时间大于5秒时，应停止连续流式冷疗。
