![]() ![]() However, because of their higher resistance, use of the Sentinel Seal and of the Thora-Klex was technically impractical even at air leaks of 4 to 5 L/min. Although uncommon, this may cause significant morbidity, resulting in dyspnea requiring repeated pleural drainage procedures. Previously demonstrated differences among the PDU in handling large air flows were not seen in this lower flow model of bronchopleural fistula. Rationale: Hepatic hydrothorax is a complication of cirrhosis in which hydrostatic imbalances result in fluid accumulation within the pleural space. An increase in suction to −40 cmH 2O did not significantly alter flow via the chest tube. Compared to water seal, −20 cmH 2O suction significantly increased the ability of all four PDU to evacuate air via the chest tube and abolished small differences in chest tube air leak seen among the PDU at water seal. ![]() The PDU were tested at 0 cm (water seal), −20 cm and −40 cmH 2O suction. After your procedure, you will have an X-ray to make sure that there is no more excess fluid or air in the space surrounding your lungs. Open a drainage kit and take out the blue emergency slide clamp. If it is: Pinch the catheter closed between your fingers. Check if your catheter is damaged, cut, or broken. Check for kinks (bends) in your catheter. In order to compare the performance of four pleural drainage units (PDU ), we created an animal model of bronchopleural fistula that simulated the type of air leak seen clinically (mean maximal flow = 5 L/min).
