Background: Despite importance of chest tube insertion in chest trauma, there is no ‎general agreement on the level of daily volume drainage from chest tube. This study ‎was conducted to compare the effectiveness and safety of chest tube removal at the ‎levels of 150 ml/day and 2oo ml/day.

Methods: Eligible patients (138) who needed replacement of chest tube (because of ‎trauma or malignancy) were randomized into two groups; control (removal of chest tube ‎when drainage reached to 150 ml/day) and trial (removal of chest tube at the level of ‎‎200 ml/day). All patients received standard care during hospital admission and a follow-‎up visit after 7days of discharge from hospital. Patients were then compared in terms of ‎major clinical outcomes using chi-squared and t-test.

Results:  From the total of 138 patients, 70 and 68 patients were randomized to control ‎‎(G150) and trial (G200) group, respectively. Baseline characteristics were comparable ‎between the two groups. Although the trial group had a shorter mean for length of ‎hospital stay (LOS) (4.1 compared to 4.8, p=0.04), their differences in drainage time ‎did not reach to the level of statistical significance (p=0.1). Analysis of data showed no ‎statistically significant differences between the rate of radiological reaccumulation, ‎thoracentesis and decrease in pulmonary sounds (auscultatory), one week after ‎discharge from hospital.‎‏

‏Conclusions: Compared to a daily volume drainage of 150 ml, removal of chest tube ‎when there is 200 ml/day is safe and will even result in a shorter hospital stay. This in ‎turn leads to a lower cost.‎
