A study testing clamping group in people with Management of Lung Cancer Patients, run by Wu Nan at 1 site in China.
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. Read more about this study

About this study
Official title: The Impacts of Intermittent Chest Tube Clamping on Chest Tube Drainage Duration and Postoperative Hospital Stay After Lung Cancer Surgery: A Prospective Study
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.
Read the detailed 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 volume≤250 mL in 24 h, (b) absence of air leakage and intrathoracic hemorrhage, and (c) absence of signs of purulent pleural effusion and atelectasis.

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.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
chest tube drainage duration (time frame: From date of operation until the date of chest tube removal, assessed up to 10 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03379350, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2021.
