Disclosed are surgical drains for use in surgical wounds. The drains are placed in the wound in the body and draw in unwanted bodily material. The drains can be of any shape, but preferably have a generally circular cross section or include a generally flat top surface, a generally flat bottom-surface and two sides connecting the top surface and bottom surface. The drain has an outer surface, two ends, a length and an interior lumen that may extend substantially along the length. At least one row of openings is formed in the outer surface along the longitudinal axis. The openings in a single row may comprise large cross-sectional openings alternating with small cross-sectional openings. If a plurality of rows are utilized, the small cross-sectional openings may not be included. It is preferred that the large cross-sectional openings in one row be offset, or staggered, from the large cross-sectional openings in a neighboring row. The flat drain may include large openings on one or more of the flat surfaces and smaller openings on the sides. It is preferred, but not required, that at least some of the openings be formed in the base of a channel formed in the outer surface of the drain.
