Abstract: 【Abstract】〓Objective〓To investigate the effect of chest surgical drainage by using modified catheter drainage in thoracic surgery. Methods〓Twenty-eight cases undergoing thoracic operation from July 2014 to December 2014 were included in the study. All patients received the intrathoracic drainage by using a narrow hose catheter with a negative pressure ball and pocket instead of traditional thick tube with water-sealed bottle. Pain degree, out-of-bed time, duration of catheter drainage, catheter obstruction, repeated thoracentesis were recorded and analyzed. Results〓Postoperative pain degree was concerned with mild pain in 15 cases, moderate pain in 11cases, and severe pain in 2 cases. And 13 cases took pain-killer, 1-2 times in 12 cases, more than 3 times in 4 cases. The fastest time to walk down bedding was 0.5-12 hours. Indwelling drainage tube stayed from 6 hours to 21 days. The volume of 24-hours-drainage ranged from 2 to 2800 ml. No catheter was found obstruction. None of patients need pleural puncture again after removal of the fine hose tube. Conclusion〓In our study, the fine hose catheter with a negative pressure ball and pocket device had a good clinical effect with small wound, free drainage, and could be indwelled for a long time.
