Restart of draining after a pause of 3 consecutive hours.
mL = mililiter, No = numberWe defined “restart of draining” as a drained volume of minimum 5 ml after the pause of three consecutive hours to avoid misinterpretation or to count fluid within the drain tube that has been pushed into the draining bag e.g. because of air in the system. The volume drained after the pause in these 8 cases was 12–29% of the total volume drained, and the median drained volume after the pause was 17.5 ml. In group A, no drains started draining again after they had stopped.
