“…In our case, the same described materials were used, but the pressure was modified due to a shortage of pressure generator and electric maintenance. For 30 min, a suction machine created negative pressure (-100 mmHg) and after ensuring that the system was sailing, suction diverged and continued by suction drain [ [7] , [8] , [9] ]. Suction drain was used to maintain negative pressure, and it allowed early discharge from hospital, therefore hospital stay was reduced significantly to 4 days if four-cycles were needed.…”
