Clinical Trial Summary
All patients undergo lateral thoracotomy or video-assisted thoracoscopic surgery (VATS) and
are operated on by the same thoracic surgical team. All patients are managed with gravity
drainage (water seal only, without suction) on the day of operation. Eligible patients are
randomized to control group or clamping group at a 1:1 ratio before 3pm on the postoperative
day. Patients in control group and those in clamping group are managed with different
protocols after 3pm on the postoperative day.
Description:
All patients undergo lateral thoracotomy or video-assisted thoracoscopic surgery (VATS) and
are operated on by the same thoracic surgical team. At the end of operation, the lung
parenchyma is submerged in sterile saline to test for air leakage, and a single 24-Fr chest
tube is placed in each patient. All patients are managed with gravity drainage (water seal
only, without suction) on the day of operation.
Once a radiograph is confirmed re-expansion of the lung on the morning of the first
postoperative day and no air leak is detected, the patient is a candidate for inclusion in
the trial. Eligible patients are randomized to control group or clamping group before 3pm on
the postoperative day.
Patients in control group are managed with gravity drainage unchangeably, while patients in
clamping group are managed with clamping protocol after 3pm on the postoperative day as
follow: the chest tube will be clamped, and the nurses will check the patient every 6 h. If
the patient has no problems with compliance, the clamp will be removed for half an hour in
the morning to record the drainage volume every 24 h. If patients develops intolerable
abnormal symptoms, such as dyspnea, pneumothorax, and severe subcutaneous emphysema after
chest tube clamping, the clamp will be removed for 30 min and be reapplied after the symptoms
have been resolved. Such patients will be placed under more rigorous surveillance after
re-clamping, which requires the medical staff to check on the patients every 2-4 hours in
order to promptly detect abnormal symptoms. If abnormal symptoms occur frequently, this
clamping protocol will be continued until another radiograph excluded the presence of
pneumothorax.
The daily output of pleural fluid was recorded. The criteria for chest tube removal were as
follows: (a) drainage volumeā¤250 mL in 24 h, (b) absence of air leakage and intrathoracic
hemorrhage, and (c) absence of signs of purulent pleural effusion and atelectasis.
