负压疗法治疗肢体缺血

目的：评价负压疗法对肢体缺血的治疗效果，方法：１９８５－０７￣１９９５－０３，我们应用自行研制的治疗机，对１６７例（２３１个肢体）肢体缺血患者进行了负压治疗，其中动脉硬化性闭塞症６２例（９１肢），血栓闭塞性脉管炎７５例（９３肢），雷诺综合征３０例（４７肢），治疗时将患肢置入密闭舱内，压力范围为－８．６６ｋＰａ￣－１７．３ｋＰａ，一般上肢为－１０．７ｋＰａ，下肢为－１３．３ｋＰａ。结果：显效１１７肢

Therapy of limb ischaemia with negative pressure

Aim: To evaluate the therapeutic effects of negative pressure on limb ischaemia. Methods: A total of 167patients (including 231 limbs) with limb ischaemia, ofwhom 62 (91 limbs) were afflicted with atherosclerosisobliterans, 75 (93 limbs) with thromboangiitis obliteransand 30 (47 limbs) with Raynaud's syndrome, were involvedin the study undertaken from July 1985 to March 1995.They received limb negative pressure treatment with the instrument designed by ourselves. The ischaemic limb to betreated was put into a sealed chamber, in which the pressure was adjusted within the range between-8. 6kpa~-17. 3kpa, usually,-10. 7 kpa for arms and -13. 3 kpa forlegs. Results: The significant effect was shown in 117 limbs(50. 64%), in which the symptoms disappeared completelyor nearly; the condition of 111 limbs (48. 05%)were improved to a certain degree; only 3 limbs (1. 31 % )remained unrelieved. The overall effective rate was up to98. 69%. Conclusion: The negative pressure therapy is effective and causes no pain or harm to patients. Therefore itis recommended as an alternative of non-operative clinicalapproach to limb ischaemia.
