Risk factors for reoperation,readmission, and early complications after below knee amputation

Background

Many patients undergoing below knee amputations (BKA) return for subsequent unplanned operations, hospital readmission, or postoperative complications. This unplanned medical management negatively impacts both patient outcomes and our healthcare system. This study primarily investigates the risk factors for unplanned reoperation following BKA.

下肢严重损伤截肢与保留的计量诊断

取２００例下肢严重损伤（截肢者与保留者各１００例），应用评分方法，根据年龄、休克、伤口污染，皮肤、肌肉肌腱、骨关节、血管及神经损伤程度进行多因素两类判别分析，对伤肢进行计量诊断．结果显示：截肢组平均２２．７４分（１７～２８分），保留组１５．７７分（１３～２１分）；判别方程Ｚ＝０．１４Ｘ１＋１．４８Ｘ２＋１．４３Ｘ３＋１．６３Ｘ４＋５．８４Ｘ５＋５．０９Ｘ６＋４．３４Ｘ７＋２．１９Ｘ８，Ｚ＊＝６７．５２．方差分析所建方程有高度显著意义（Ｐ＜０．００５）．各因素对方程的贡献率以肌肉严重损伤对肢体威胁最大，其次为血管损伤，再次为骨关节损伤．原资料回代验证准确率为９８％．由此认为，该方程对临床下肢严重损伤的伤情判断及决定伤肢保留与否有重要价值．     

Amputation in elderly and high-risk vascular patients

Fifty-eight patients underwent lower limb amputation for arterial disease over a 30-month period. Mean age of the patients was 72 years. Cardiopulmonary and metabolic risk factors were present in the majority of the patients. Postoperative one-year and three-year mortality rates were 24, 40, and 76%, respectively. Contralateral amputation was required in one-third of the patients after a mean period of eight months. Only younger and healthier patients returned to a meaningful social life after appropriate prosthetic fitting. In view of the high mortality and morbidity rates, above-knee amputation seems a better choice than below-knee amputation in these elderly and high-risk patients.     

Femoral Pseudoaneurysm in Drug Addicts—Excision without Revascularization is a Viable Option

PURPOSE: To present a series of patients presenting with femoral pseudoaneurysm. RESULTS: Seventeen patients who presented with a femoral pseudoaneurysm during a 1 year period were included in this study. Parenteral drug abuse was the most common aetiological factor. The femoral artery was most commonly involved at its bifurcation. Sixteen patients (94%) had excision of the pseudoaneurysm with ligation of vessel and debridement without any revascularization and one patient (6%) had reverse saphenous grafting after excision and ligation of vessels. Four amputations (23%) were performed. Three (17%) were major limb amputations, which included one above knee and two below knee amputations. Four patients (23%) developed intermittent claudication. CONCLUSION: Excision of the pseudoaneurysm with ligation of vessels and wide debridement without immediate revascularization in infected pseudoaneurysms is a safe and effective treatment.     

GustiloⅢB和ⅢC高能量胫骨骨折--截肢与保肢的比较

截肢和保肢患者长期的功能和心理结果相似。如果早期不截肢而采取保肢,就必须考虑到:二期截肢的风险(5%～14%)、潜在的并发症(保肢术通常更高)以及住院时间延长。由于胫骨骨折严重程度不同采取的治疗可能不同(G ustiloⅢC型比ⅢB型更可能截肢),这使得对比很困难,而且相关的队列研究文献很少。     

Amputation of a crossover 2nd toe in the presence of hallux valgus

Background: There are many surgical procedures for the correction of hallux valgus and crossover 2nd toe deformity. Amputation of a crossover 2nd toe is often performed as a salvage procedure if the primary 2nd toe corrective procedure fails.Aims: To assess the outcomes of amputating a crossover 2nd toe in the presence of hallux valgus in elderly patients above 70 years old; as a primary procedure.Materials and methods: Seven patients (8 ft) underwent amputation of their crossover 2nd toe. A disease specific questionnaire using a Visual Analogue Scale (VAS) was implemented measuring pain, deformity, discomfort, and walking distance.Results: The mean age of the patients was 82 years old, range 74–89 years old. Amputation of the 2nd toe significantly reduces pain, discomfort and the appearance of deformity, there was no difference in the patient’s walking distance after surgery.Conclusion: We recommend this type of surgery as a primary procedure in elderly patients above 70 years old, if the first ray is not causing symptoms.     

地震救援中现场截肢的探讨

目的探讨地震救援中现场截肢手术适应证、手术方法及伦理问题。方法映秀镇地震救援中现场截肢2例共3个肢体，采用局部麻醉，截肢平面靠近压迫物。术后补充等张盐水，补液速度1．5L／h，静脉滴注5％碳酸氢钠溶液150mL。口服头孢克肟胶囊，400mg顿服。结果截肢后2例患者均未出现严重并发症，次日送后方医院行二次截肢。结论灾难救援中现场截肢必须综合考虑，严格掌握适应证，必要的截肢可以挽救伤员生命。
