通常以肋间插管闭式引流术治疗自发性气胸。本文对此进行了前瞻性研究,以评价吸引引流的效果和拔除导管的最佳时间。1979～1980年间,对有症状的或肺压缩20%以上的53例自发性气胸患者,均经套管针插入A13FG 聚乙烯导管进行引流,每日胸透复查。病人随机分为两组,甲组立即进行负压吸引(先用8cmH_2O,若24小时后肺未复张,调整至20cmH_2O),乙组不用吸引。每组再随机分为早期拔管组(一经胸透发现肺复张即拔管)和延缓拔管组(肺复张后夹管观察2天,若肺不
Closed intracavitary drainage is usually used to treat spontaneous pneumothorax. In this paper, a prospective study to evaluate the effect of suction and drainage catheter removal and the best time. Between 1979 and 1980, 53 patients with spontaneous pneumothorax, who had symptomatic or pulmonary compression of more than 20%, were allotted to the A13FG polyethylene catheter through a trocar for daily chest thoracotomy. Patients were randomly divided into two groups, Group A immediately negative suction (first with 8cmH2O, if 24 hours after the lung is not Zhang Zhang, adjusted to 20cmH2O), Group B do not attract. Each group was then randomly divided into early extubation group (once the thoracodorsis was found pulmonary extubation that extubation) and delayed extubation group (pulmonary ducts observed after 2 days, if the lungs are not
