Abstract
TECHNIQUE a sterilised drain set is used; small side holes are made in the tubes using scissors (average 6–10 holes) (Fig 1). The drip bag is emptied and a negative pressure is created (Fig 2). (Saline is used for the operation and is not discarded.) The drip set is connected to the bag to act as a suction drain. The roller clamp can be used to control flow and prevent the loss of negative pressure when changing the bottle. it can also be used as a simple drain. The closed drainage system helps to prevent infection. DISCUSSION We have used this technique in over 50 patients in Gadarif Teaching hospital. it is effective, cheap, removal is simple and we did not encounter any problems.
