Arterial hypoxaemia is observed during operation and also in the recovery room. Hypoxaemia during operation may be due to altered pulmonary mechanical conditions, drug-induced physiological changes and technical errors. Early postoperative hypoxaemia is frequently observed after general anaesthesia and may, among other things, be due to diffusion hypoxaemia, hyperventilation-induced hypoventilation, residual curarization, hypoventilation induced by sedatives or analgesics and ventilation/perfusion alterations. The clinical significance of peroperative and early postoperative hypoxaemia is not yet elucidated and treatment consists primarily of increasing the oxygen concentration in the inspired air.

Review[Therapeutic pleurodesis in spontaneous pneumothorax, malignant pleural effusion, heart insufficiency and chylothorax].
Treatment with pleurodesis is employed in spontaneous pneumothorax, in pleural effusion due to neoplastic disease, intractable transudate and chylothorax. When this treatment is employed in spontaneous pneumothorax, randomized studies show a lower recurrence rate when drainage is supplemented by a sclerosing agent. Pleurodesis alone scarcely alters the recurrence rate in pneumothorax. ⋯ No randomized studies of pleurodesis in congestive heart failure and chylothorax were found. Pleurodesis is not recommended in the treatment of congestive heart failure because of reports of development of contralateral pleural effusion after successful pleurodesis. In chylothorax, pleurodesis is the last resort.
