A new closed-system device for the diagnosis and treatment of pneumothorax was evaluated in ten New Zealand white rabbits and compared with and open-system needle. The closed-system device proved to be safe for diagnostic thoracentesis. There were no pneumothoraces as a result of the procedure with the closed-system device as confirmed by chest roentgenograms and pleural pressure measurements. In contrast, 70% of the diagnostic thoracenteses with the open-system needle were associated with pneumothorax documented by x-ray films and a significant increase in mean pleural pressure. The new apparatus was more efficacious for evacuation of pneumothoraces because complete air removal occurred in 90% of the rabbits as compared with 60% of trials with the open-system needle. If the efficacy of the new closed-system device proves to be good in human infants, the pediatrician encountering a tension pneumothorax in the newborn can use a completely assembled system that is safe for diagnosing and treating this acute life-threatening condition.
一种用于气胸诊断和治疗的新型封闭系统装置在十只新西兰白兔身上进行了评估，并与开放式针头进行了比较。结果表明，该封闭系统装置用于诊断性胸腔穿刺术是安全的。胸部X光片和胸膜压力测量结果证实，使用封闭系统装置进行操作后未出现气胸。相比之下，使用开放式针头进行的诊断性胸腔穿刺术中，70%出现了X光片记录的气胸，且平均胸膜压力显著升高。这种新装置在气胸引流方面更有效，因为90%的兔子实现了完全排气，而使用开放式针头的试验中这一比例为60%。如果这种新型封闭系统装置在人类婴儿中被证明效果良好，那么遇到新生儿张力性气胸的儿科医生可以使用一个完全组装好的系统，该系统对于诊断和治疗这种危及生命的急性病症是安全的。
