肺結核症による肺全切除術後長期経過例の検討

抄録

Management of respiratory insufficiency following sequela of pulmonary tuberculosis is one of the important problems to be solved. We carried out pulmonary function tests in 48 patients who had received pneumonectomy a long ago in order to make guidelines for management of such patients.
Subjective symptoms and blood gas level showed a good correlation with % VC. Since PaO₂was kept above 65 mmHg when % VC was above 40, this level of 40% VC was considered to be a functional lower limit for daily life. Electrocardiogram finding was a simple index for everyday management. However, as some cases with normal blood gas level showed pulmonary P, the blood gas level should be measured and used together to evaluate the capacity for daily life. Many of the patients who received thoracoplasty in combination with pneumonectomy and the remaining lung did not expand well fell in severe pulmonary insufficiency and some died. Prevention of infection as well as of overwork and early management of respiration will lead to longer survival of these patients.
