Studies in the adult population have showed that using a digital system allows for objective criteria regarding when it is safe to remove the chest tube and thus decreased time of chest tube drainage. This has also translated into decreased length of stay and cost(2, 6-8). Early data suggests that these same benefits may apply to pediatric patients, however a prospective randomized trial comparing the two systems has not been performed(9, 10).",[13],"Device: Madela THOPAZ Digital Device",{"label":15,"type":10,"description":16,"interventionNames":17},"Atrium Dry Suction Control Water Seal Chest Drain","there are several limitations to this analog system. First, although the system can manually be set to a certain negative pressure, the actual pressure experienced by the patient varies dependent on the amount of fluid in the tube and the level of the device relative to the patient(2). This leads to inconsistency of pleural pressure which has been associated with an increased incidence of prolonged air leak(2). Second, the analog system relies on a water chamber where bubbles are visualized to indicate an air leak. Air leaks are a common cause of increased duration of chest tube drainage and subsequent length of stay(3). There is high interobserver variability in the subjective measurement of air leaks when using the analog system thus exacerbating the amount of time the chest tube remains in the patient as well as the length of stay(4, 5).",[18],"Device: Atrium Analog Device",[20,26],{"type":21,"name":22,"description":23,"armGroupLabels":24,"otherNames":25},"DEVICE","Madela THOPAZ Digital Device","Digital drainage systems use electronic sensors to measure changes in pressure and thus may allow for quantification of the degree of air leak continuously and provide a graphical representation of the trend over time.

The digital system allows for stored data, objective measurement of air leaks as well as maintaining a constant pleural pressure. The adult literature describes multiple benefits of using a digital drainage system, only two studies to date have looked at pediatric patients. In the adult literature, reported benefits include shorter chest tube drainage times, decreased length of stay, cost savings and fewer chest x-rays. To date, there have been no prospective randomized controlled trials comparing digital versus analog chest tube drainage systems in pediatric patients. In addition, the only two pediatric studies which looked at the potential benefits of a digital drainage system only looked at its use in patients who underwent pulmonary resection. Thus, a gap in the literature exists for a prospective trial determining if there is benefit to using a digital vs analog drainage system in pediatric patients requiring a chest tube. The investigators hypothesize that pediatric patients who are placed on the Thopaz+ digital drainage system will have decreased duration of chest tube drainage, fewer chest x-rays and shorter duration of air leaks compared to patients using a traditional analog chest tube drainage system. This will be the first prospective randomized study exploring the potential benefits of using a digital chest tube drainage system in pediatric patients.",[78],"Air Leakage",[80],"chest tube","2026-03-26",{"date":83,"type":84},"2026-04-01","ACTUAL",{"date":86,"type":84},"2023-08-15",{"date":88,"type":72},"2027-12-01",{"name":5,"class":6},1]
