人体血液pH值的极限,一般认为在6.8～7.8之间,超出此范图则难以生存。我们遇见1例重症肌无力并发急性呼吸性碱中毒者,动脉血pH值高达7.932,患者尚能耐受,且临床无特殊症状,现报告如下。患者女性,29岁,工人。反复眼睑、吞咽及四肢肌肉无力,新斯的明试验阳性,诊断为重症肌无力1年余。症状加重伴呼吸困难,气管切开7个月,一直使用抗胆碱酯酶药物及呼吸机以IPPV方式通气。为进一步诊治,以简易呼吸器吸入纯氧于1985年3月23日10时30分由他院用担架送入院。查体:T36℃,P64次,Bp96/60。发育正常,营养差,神清,表情呆
The limits of human blood pH value, generally believed that between 6.8 to 7.8, beyond this paradigm is difficult to survive. We met one case of myasthenia gravis complicated by acute respiratory alkalosis, arterial pH value up to 7.932, the patient is still able to tolerate, and no special clinical symptoms, are as follows. Patient female, 29 years old, worker. Repeated eyelids, swallowing and limb muscle weakness, neostigmine test positive, diagnosis of myasthenia gravis more than 1 year. Symptoms worse with dyspnea, tracheotomy for 7 months, has been using anticholinesterase drugs and ventilator IPPV ventilation. For further diagnosis and treatment, inhaled pure oxygen with a simple respirator was brought to hospital by a stretcher at 10:30 on 23 March 1985. Physical examination: T36 ℃, P64 times, Bp96 / 60.
