Vibration Exposure Safety Guidelines for Surgeons Using Power-Assisted Liposuction (PAL)
Aesthetic Surgery Journal
|December 18, 2020
Summary
Plastic surgeons using power-assisted liposuction (PAL) face occupational vibration exposure. Exceeding 1.5 hours daily increases hand-arm vibration syndrome risk, necessitating safety strategies.
Area of Science:
- Occupational health
- Biomedical engineering
- Plastic surgery
Background:
- Power-assisted liposuction (PAL) is increasingly popular among plastic surgeons.
- Surgeons using PAL devices risk occupational exposure to hand-transmitted vibration.
- This exposure can lead to hand-arm vibration syndrome (HAVS), a serious neurovascular condition.
Purpose of the Study:
- To quantify vibration exposure during surgical use of a PAL device.
- To establish recommendations for the safe utilization of PAL systems.
- To mitigate the risk of occupational health issues for surgeons.
Main Methods:
- Vibration emission from a MicroAire-650 PAL system was measured.
- Measurements were taken using a vibration data logger under laboratory and clinical conditions.
- Data from 13 liposuction surgeries were analyzed and compared to safety standards.
Main Results:
- Mean vibration magnitude during liposuction was 5.69 ± 0.77 m/s², exceeding the manufacturer's stated 3.77 m/s².
- Larger cannula size significantly increased vibration transmission.
- Cannula size was the primary factor influencing vibration magnitude.
Conclusions:
- PAL device usage necessitates recommendations to prevent excessive occupational vibration exposure.
- Safe utilization of the MicroAire-650 is limited to under 1.5 hours per day.
- Exposure exceeding 1.5 hours/day increases HAVS risk, requiring vibration-reducing strategies; exceeding 6 hours/day exceeds safety limits and mandates halting use.
