To quantitatively and qualitatively evaluate the surgical waste produced from several common surgical procedures, define categories of waste that might be readily separated for alternative disposal practices or substitution, and determine the change in surgical waste output that elimination or alternative handling methods may effect.
A case series evaluating the surgical waste from five types of surgical procedures including operations of the back, heart, abdomen, hip and knee, and herniorrhaphies, prospectively identified and allocated at the availability of the investigator.
A single tertiary community teaching hospital.
Weight, volume, and percentage of disposable linen, paper, and plastic plus miscellaneous material from surgical waste with a later subset separating plastics from miscellaneous items to completely identify all categories.
Surgical waste weighing 610.5 lb (274.7 kg) and occupying 171.6 cu ft (5.1 m3) from 27 cases was examined. Disposable linens accounted for 39% of the weight; paper, 7%; plastic, 26%; and miscellaneous waste, 27%. By volume, disposable linen and paper accounted for 69%; plastic, 23%; and miscellaneous waste, 7%. Disposable linen, paper, and recyclable plastic accounted for 73% +/- 7% (mean +/- SD) by weight and 93% +/- 4% by volume of total surgical waste.
Nationally, annual surgical waste from these five procedures weighs 5.1 x 10(7) lb (2.3 x 10(7) kg) and occupies 1.4 x 10(7) cu ft (4.0 x 10(5) m3). By using reusable linen products and engaging in recycling methods currently available and feasible, we estimate that weight reductions of 73% and volume reductions of 93% in surgical waste are possible.
对几种常见外科手术产生的手术废弃物进行定量和定性评估，确定可轻易分离以便进行替代处置或替代的废弃物类别，并确定消除或采用替代处理方法可能对外科手术废弃物产量产生的变化。
一项病例系列研究，前瞻性地识别并分配了来自包括背部、心脏、腹部、髋部和膝部手术以及疝修补术在内的五种外科手术的手术废弃物，由研究者在可获取时进行研究。
一家三级社区教学医院。
手术废弃物中一次性亚麻制品、纸张、塑料以及其他杂物的重量、体积和百分比，随后对一个子集将塑料与其他杂物分开，以完全确定所有类别。
检查了来自27例手术的重达610.5磅（274.7千克）、体积为171.6立方英尺（5.1立方米）的手术废弃物。一次性亚麻制品占重量的39%；纸张占7%；塑料占26%；其他杂物占27%。按体积计算，一次性亚麻制品和纸张占69%；塑料占23%；其他杂物占7%。一次性亚麻制品、纸张和可回收塑料按重量占手术废弃物总量的73%±7%（均值±标准差），按体积占93%±4%。
在全国范围内，这五种手术每年产生的手术废弃物重达5.1×10⁷磅（2.3×10⁷千克），体积为1.4×10⁷立方英尺（4.0×10⁵立方米）。通过使用可重复使用的亚麻制品并采用目前可用且可行的回收方法，我们估计手术废弃物的重量可减少73%，体积可减少93%。
