Tourniquet cuff pressure | 合法醫療器材資訊網

Tourniquet use is effective in producing a bloodless field. It is recommended that the least effective pressures be used to minimize tissue microstructure and biochemical damage from tourniquet application. When applied at the thigh, the minimum effective tourniquet pressure is 90 to 100 mm Hg above systolic BP, and in a normotensive, nonobese patient, pressure of 250 mm Hg is sufficient. Similarly, an arm tourniquet pressure of 200 mm Hg is recommended. The purpose of this survey was to assess the tourniquet pressures used by orthopaedic surgeons, both academic and community based, and their familiarity with associated literature.

Materials: A Website-based survey was distributed to a random sample of academic and community-based surgeons. Respondents were asked the upper and lower-extremity tourniquet pressures they routinely use. They were asked if they were able to cite or were aware of literatu...
