As power-assisted liposuction (PAL) gains in popularity, plastic surgeons operating these devices experience occupational exposure to hand-transmitted vibration, which can result in hand-arm vibration syndrome, a debilitating neurovasculopathy.
The objective of the study was to determine vibration exposure from the utilization of a PAL device during surgery to generate recommendations for safe use.
Vibration emission of a commonly utilized PAL system (MicroAire-650, Surgical Instruments, Charlottesville, VA) was examined employing a vibration data logger under both controlled laboratory conditions and during 13 typical liposuction cases. Data were analyzed and compared with established safety limits of vibration exposure.
The experiments demonstrated a mean vibration magnitude of typical liposuction surgeries to be 5.69 ± 0.77 m/s2 (range, 4.59-6.27 m/s2), which is significantly higher than the manufacturer declared value of 3.77 m/s2. Cannula size was shown to be the most significant contributor to vibration magnitude, with larger cannulas causing more vibration transmission.
These results indicate that recommendations must be made to prevent undue occupational exposure to vibration from PAL. The MicroAire-650 can generally be safely utilized for less than 1.5 h/d. At exposure levels >1.5 h/d, there is increased risk of developing vibration-related injuries, and vibration-reducing strategies should be implemented. At exposure levels >6 h/d, the safety limit is exceeded and there is significantly increased risk of developing hand-arm vibration syndrome and vibration exposure should be halted.
随着动力辅助吸脂术（PAL）的普及，操作这些设备的整形外科医生会接触到手传振动，这可能导致手部-手臂振动综合征，这是一种使人衰弱的神经血管病。
本研究的目的是确定手术中使用 PAL 设备时的振动暴露情况，从而为安全使用提供建议。
在受控实验室条件下和 13 例典型吸脂手术中，使用振动数据记录仪检查常用 PAL 系统（MicroAire-650，Surgical Instruments，Charlottesville，VA）的振动排放。对数据进行分析，并与已建立的振动暴露安全限值进行比较。
实验表明，典型吸脂手术的平均振动幅度为 5.69±0.77 m/s2（范围为 4.59-6.27 m/s2），显著高于制造商宣称的 3.77 m/s2。管腔尺寸被证明是振动幅度的最大贡献者，较大的管腔导致更多的振动传递。
这些结果表明，必须提出建议以防止 PAL 引起的不必要的职业性振动暴露。MicroAire-650 通常可以安全使用不超过 1.5 小时/天。在暴露水平>1.5 小时/天的情况下，发生与振动相关的损伤的风险增加，应实施减少振动的策略。在暴露水平>6 小时/天的情况下，安全限值被超过，发生手部-手臂振动综合征的风险显著增加，应停止振动暴露。
