Sequential compression devices (SCDs) reduce deep venous thrombosis in postsurgical patients, but the use is hindered by poor compliance.
General and orthopedic surgery patients (n = 67) were randomized to standard- or battery-powered SCDs. Compliance was documented hourly. Nurses and patients were issued a survey to assess barriers to compliance and device satisfaction.
Compliance with standard SCDs was 47% compared with 85% with battery-powered SCDs (P < .001). The most common barriers identified by nurses and patients were ambulation and transfers, which were mitigated with the battery-powered device. A majority (79%) of those issued a battery-powered device reported no major problems compared with only 14% of patients issued a standard device (P < .005).
The dual venous thromboembolism prevention strategies of early mobilization and SCD utilization can be met with the appropriate equipment.
序贯加压装置（SCDs）可降低术后患者深静脉血栓形成的风险，但因依从性差而使用受限。
将普通外科和骨科手术患者（n = 67）随机分为标准型或电池供电型SCDs组。每小时记录一次依从性情况。向护士和患者发放调查问卷，以评估依从性障碍和设备满意度。
标准型SCDs的依从率为47%，而电池供电型SCDs的依从率为85%（P < .001）。护士和患者指出的最常见障碍是行走和转移，而电池供电型设备可缓解这些问题。使用电池供电型设备的患者中，大多数（79%）报告无重大问题，而使用标准型设备的患者中只有14%报告无重大问题（P < .005）。
早期活动和使用SCDs的双重静脉血栓栓塞预防策略可通过适当的设备得以实现。
