用高压氧（ＨＢＯ）疗法辅以常规方法治疗急性ＣＯ中毒并发自压伤２９例。具体方法是，在０．２５ＭＰａ压力下，戴面罩间歇吸纯氧两次，每次３０分钟，每日治疗一次，平均治疗３５次。结果：１７例治愈，４例好转，２例无效（其中１例死亡），６例因故中断治疗，有效率达７２％。本病易与外伤、血肿、骨拆、脓肿、蜂窝织炎、血栓性静脉炎、荨麻疹、烫伤等混淆，故需加以鉴别。急性ＣＯ中毒并发自压伤一经确诊，应早期、足量、首选高压氧治疗，并注意患处禁用扩血管药、热敷、按摩及红外线照射。 29 cases of acute CO poisoning complicated by self-pressure injury were treated with hyperbaric oxygen (HBO) therapy and conventional method. The specific method is, at 0.25MPa pressure, wearing a mask intermittent inhalation of oxygen twice, each time for 30 minutes, once daily treatment, the average treatment of 35 times. Results: 17 cases were cured, 4 cases improved, 2 cases were ineffective (including 1 case died), and 6 cases were treated by interruption. The effective rate was 72%. The disease easily with trauma, hematoma, bone demolition, abscess, cellulitis, thrombophlebitis, urticaria, scalds and other confusion, it needs to be identified. Acute CO poisoning complicated by injury Once diagnosed, early, adequate, preferred hyperbaric oxygen therapy, and pay attention to the affected area vasodilator, heat, massage and infrared radiation.
