An austere field amputation can be a life-saving procedure for an entrapped patient when standard equipment is not available or operable. The objective of this study was to use hand tools to perform cadaveric amputations in < 2 minutes.
Timed guillotine amputation of the extremities on three cadavers was attempted using four available hand tools: a multitool, a rescue tool, a hunting knife, and a fixedblade knife. The primary outcome was successful amputation of the extremity in < 2 minutes.
Amputation success was different among the tools. The multitool amputated 78% of attempts; the hunting knife, 67%; the rescue knife, 56%; and the fixed-blade knife, 44%. The distal tibia/fibula and radius/ ulna were amputated successfully in 100% of attempts, whereas none of the tools could amputate the femur. The multitool received the best subjective ranking - 1.4 (p = .001) - by amputators, with the fixed-blade knife receiving the worst score.
In the rare circumstance that an emergent field amputation requires a hand tool, the multitool is a capable instrument for a distal extremity amputation.
在标准设备不可用或无法操作的情况下，对被困患者进行简陋的野外截肢术可能是一种救生程序。本研究的目的是使用手动工具在<2 分钟内完成尸体截肢。
尝试使用四种可用的手动工具（多用工具、救援工具、猎刀和固定刀片刀）对三个尸体的四肢进行定时断头截肢。主要结果是成功地在<2 分钟内完成肢体截肢。
不同工具的截肢成功率不同。多用工具截肢成功率为 78%；猎刀为 67%；救援刀为 56%；固定刀片刀为 44%。100%的尝试都成功地切断了胫骨/腓骨和桡骨/尺骨，但没有一种工具可以切断股骨。截肢者对多用工具的主观评分最高-1.4（p=0.001），而固定刀片刀的评分最差。
在紧急野外截肢需要手动工具的罕见情况下，多用工具是一种用于远端肢体截肢的有效工具。
