Early diagnosis of the extent of bone and soft tissue damage is a very important step in treating a frostbite victim. The diagnostic use of Tc-99m-phosphates in assessing the viability of soft tissue and bone in frostbite was evaluated in the early post-thaw period. Four patients were treated with a combination of warm baths, rehydration, vasodilators, epidural block, fasciotomy, and debridement. Six scans were done to stage involvement. In three of the four cases, final involvement could be determined as early as the third day. When a specific level of soft tissue or bone uptake was determined, future scanning showed either improvement, or no change in three of the four patients. In our experience, Tc-99m-phosphate scans represent an improvement over other diagnostic tests for viability of tissues.
早期诊断骨与软组织损伤的程度是治疗冻伤患者的非常重要的一步。在解冻后的早期阶段，对锝-99m磷酸盐在评估冻伤中软组织和骨骼活力的诊断用途进行了评估。4例患者接受了温水浴、补液、血管扩张剂、硬膜外阻滞、筋膜切开术和清创术联合治疗。进行了6次扫描以确定受累程度。在4例中的3例中，早在第三天就能确定最终受累情况。当确定了软组织或骨骼摄取的特定水平时，后续扫描显示4例患者中有3例病情改善或无变化。根据我们的经验，锝-99m磷酸盐扫描比其他组织活力诊断测试有所改进。
