Drains Show Bleeding Early
Captions available
The idea
Drain output gives an early signal of bleeding after surgery.
In practice
A moderate amount of fresh, bright red blood in a drain or on a dressing is one of the cues of postoperative bleeding the textbook describes.
Where people slip
Unusual drain output is reported promptly so the surgeon can evaluate it.
