Detailed Description
The investigators will conduct a randomized controlled trial enrolling patients undergoing elective VATS-lobectomy. Patients will be randomly assigned into two groups through web-based randomization. Air leak will be measured intraoperatively by submersion tests and postoperatively using standard electronic chest tube devices (Thopaz) with a regulated pressure of -10 cmH2O. If an air leak is present on the 1st postoperative day (20 ml/min or greater for at least 6 hours) patients will be invited to participate in this study.
Following informed consent, the patient is randomized on a web-based randomization module to receive intervention or observation. The intervention group will receive intrapleural instillation of autologous blood in accordance with the standard blood patch protocol at Odense University Hospital. In short, 120 ml autologous blood will be drawn from simple venous puncture and immediately injected through the drain into the pleural cavity followed by flushing with 50ml of saline. No anticoagulation or coagulating agents will be added. All other aspects of the patient's postoperative management will be according to the department's standard protocols.
Standard preoperative information on smoking status, medications, medical history of lung diseases, BMI, spirometry as well as DLCO measurements will be recorded. Detailed information about the surgical treatment will also be recorded (site of anatomical resection, adherences, standard perioperative assessment of air leakage, and type of mechanical linear staplers).
All chest drains will be connected to a standard electronic chest tube device (Thopaz) for continuous recording of air leakage and the drain is removed during daytime or evening shifts when air leakage has ceased to 20 ml/min or less for at least 6 hours according to the standard postoperative management. In addition, all included patients will undergo standard postoperative observations, including recording of vital signs (blood pressure, heart rate, fever, saturation-%) and standard blood samples (CRP and leukocyte count) on postoperative day 2 and subsequent daily if there is a suspicion of infection, pleural effusions, empyema and drain-site infections. Pain will be assessed twice daily using a standardized 0-10 visual analog scale (VAS) where 0 represents no pain and 10 the worst imaginable pain.
Electronic recordings of air leakage from the electronic chest tube device will be analyzed from drain placement in the operating room, until drain removal. If air leakage is still present on postoperative day 7, treatment is considered a failure and further management will be individualized by the responsible surgeon including the need for re-operation in accordance with the department's standard of care.
In the control group everything listed above will apply in the same manner except the intrapleural instillation of autologous blood.
