16.7 Drainage systems: changing the dressing around the drain site for both open and closed drains
Essential equipment
- Personal protective equipment
- Dressing trolley or other suitable surface
- Detergent wipe
- Sterile fluids for cleaning and/or irrigation, e.g. 0.9% sodium chloride
- Appropriate absorbent dry dressing (required special features of a dressing should be referred to in the patient's nursing care plan)
- Dressing pack, including sterile towel, gauze, gallipot and disposable bag
- Gloves: one disposable pair, one sterile pair
- Hypoallergenic tape
Optional equipment
- Any extra equipment that may be needed during the procedure, e.g. sterile scissors, forceps and microbiological swab
Pre‐procedure
ActionRationale
- 1.
Check the medical notes to identify which drain is to be removed. Introduce yourself to the patient, explain and discuss the procedure with them, and gain their consent to proceed.
- 2.Check patient comfort, for example position and pain level. Offer the patient analgesia as described on their chart or encourage self‐administration via a patient‐controlled analgesia pump (if applicable) and allow appropriate time for the medication to take effect.To promote patient comfort (NMC [152], C).
- 3.Clean the trolley/tray per local trust guidelines and gather the equipment, checking the sterility and expiry date of equipment and solutions, and place everything on the bottom of the trolley.To minimize the risk of infection (Loveday et al. [110], R).
- 4.Take the trolley/tray to the bed and adjust the bed to the correct height to avoid stooping.To promote good manual handling. E
- 5.Wash and dry hands thoroughly and put on a fresh an apron.To minimize the risk of infection (NHS England and NHSI [137], C).
Procedure
- 6.Remove the dressing pack from the outer pack and place it on top of the clean dressing trolley/tray. Using aseptic technique, open the packaging of the other equipment required during the procedure (sterile gloves, dressing, etc.) and place the contents onto the sterile field of the opened dressing pack.To minimize the risk of infection (Loveday et al. [110], R).
- 7.Expose the drain site, adjusting the patient's clothes to expose the wound, taking care to maintain their dignity.To minimize the amount of skin exposed; to maintain dignity. E
- 8.Wearing disposable gloves, remove the dressing covering the drain site and place it in a soiled dressing bag away from the sterile field.
- Closed drains may have a small sterile gauze dressing surrounding the exit site.
- Open drains will be covered with either a wound drainage bag (if copious exudate) or a small, absorbent, non‐adhesive sterile gauze dressing (if only minimal exudate). Once the drainage bag/dressing has been removed from an open drain, the volume and character of exudate should be measured and recorded. If requested by the surgical team, gauze dressings can be weighed once saturated to ascertain the volume of drainage.
To minimize the risk of infection (Loveday et al. [110], R). - 9.Observe the drain to ensure the skin suture holding the drain in position is intact.To ensure the drain is well secured and not withdrawn or retracted. Dislodgement can increase the risk of infection, erosion into adjacent structures (e.g. blood vessels or organs) and irritation to surrounding skin. E
- 10.Observe the skin surrounding the drain site for signs of excoriation, fluid collection or infection (inflammation of wound margins, pain, oedema, purulent exudate or pyrexia). Note: swabs of wound and drain sites should only be taken if infection is suspected.
- 11.Using aseptic technique, clean the surrounding skin with an appropriate sterile solution, such as 0.9% sodium chloride.
- 12.If appropriate, cover the drain site as follows.
- Closed drains should only be covered with a non‐adherent, absorbent dressing if there is exudate or to promote patient comfort.
- Open drains should be covered with a wound drainage bag (if exudate copious) or a small, absorbent, non‐adhesive sterile gauze dressing (if only minimal exudate).
To allow effluent to drain, prevent excoriation of the skin, promote patient comfort and contain any odour. E
Post‐procedure
- 13.If applicable, tape the dressing securely. If the drain is attached to a drainage bag or bottle, it should also be secured at one other point (e.g. with adhesive tape).To prevent the drain coming loose. E
- 14.If the drain is attached to a drainage bag or bottle, this should not be placed on the floor but placed below the level of the wound to allow drainage. If the drain is attached to a suction drain, ensure this is working correctly.To ensure continuity of drainage. Ineffective drainage can result in oedema or haematoma. To minimize the risk of cross‐infection (Hess [78], E).
- 15.Check dressing/bag is secure and comfortable for the patient.For patient comfort. E
- 16.Dispose of all clinical equipment in the clinical waste bag or sharps bin according to local trust guidelines.To ensure safe disposal. E
- 17.Document in the patient's notes that the dressing has been changed, and report any unusual signs or complications to surgical colleagues (NMC [152]). If the volume of exudate on the dressing has been measured, this should be documented on the fluid balance chart.To ensure effective communication and instructions for ongoing care. For accurate documentation of drainage (NMC [152], C).
