Suction drainage by means of a mechanical drainage apparatus may be ordered by the physician.

These suction devices are designed to provide controlled, low-pressure suction to avoid injury to mucous membranes.

Two commonly used electric powered pumps are the Gomco and Emerson pumps. Be certain to read the manufacturer’s instructions and local SOP before attempting to use this equipment. In hospital areas such as a recovery room or intensive care area, a special suction device may be available for use with a wall suction outlet.
