What are the different surgical wound drains?

Surgical wound drains are medical devices used to remove fluids, such as blood, pus, or exudate, from a surgical wound. They help prevent infection and promote healing by allowing the wound to drain properly.

There are different types of surgical wound drains, each with its own specific design and purpose. Some of the most commonly used wound drains include:

Jackson-Pratt (JP) drains: These drains are made of flexible plastic tubing with a collection bulb attached at one end. The bulb is placed inside the wound and the tubing is connected to a suction device, which draws the fluids out of the wound. Jackson-Pratt drains are often used after surgeries involving extensive tissue dissection, such as mastectomies or abdominal surgeries.

Hemovac drains: Hemovac drains are similar to Jackson-Pratt drains but have a flat, rectangular shape instead of a round bulb. They are also made of flexible plastic tubing and are connected to a suction device. Hemovac drains are often used in wounds that are expected to produce a large amount of fluid, such as surgical sites involving the removal of large tumors.

Wound VAC therapy drains: Wound VAC (vacuum-assisted closure) therapy drains are a type of wound drain that uses negative pressure to promote wound healing. They consist of a foam dressing that is placed over the wound and connected to a vacuum pump. The negative pressure helps to draw fluids out of the wound and promotes the formation of new tissue. Wound VAC therapy drains are often used in complex wounds that are slow to heal, such as diabetic foot ulcers or pressure sores.

Closed suction drains: Closed suction drains are used to remove fluids from a surgical wound without exposing the wound to the outside environment. They consist of a collection canister connected to a suction device by tubing. The tubing is inserted into the wound and the canister is placed below the level of the wound to ensure proper drainage. Closed suction drains are often used after orthopedic surgeries, such as knee or hip replacements.

Penrose drains: Penrose drains are simple drains made of a thin, flat rubber tube. They are placed in the wound to provide a path for fluids to drain. Penrose drains are often used in superficial wounds or wounds that are not expected to produce a large amount of fluid.

Sump drains: Sump drains are large-bore drains that are used to drain large amounts of fluid from a surgical wound. They are made of a thick, corrugated plastic tube with a collection bag attached at one end. Sump drains are often used after surgeries involving the removal of large tumors or abdominal surgeries.

The type of surgical wound drain used will depend on the specific needs of the patient and the type of surgery performed. The surgeon will select the most appropriate drain based on factors such as the location and size of the wound, the expected amount of fluid production, and the patient's overall health.
