II. Indications
- Drains are placed within surgical wounds to remove excess fluid, blood or pus
- Decrease risk of infection, edema and generally decrease healing time
III. Mechanism
- Surgical Drain components (e.g. Jackson-Pratt Drain or JP Drain)
- Drain tubing with optional absorbent material on one end (placed in wound bed)
- Suction/Squeeze Bulb or spring reservoir serves as a collection device
IV. Management: Low Output Drain
- Consult surgical team if available
- Review drain history
- Placement date and indication (e.g. surgical procedure, complications)
- Logged drain output per day
- Evaluate drain site
- Skin entry site (e.g. signs infection, local edema)
- Evaluate drain tubing for integrity (e.g. holes, plugging)
- Evaluate collection bulb
- Empty the collection bulb, and squeeze the bulb to recreate vacuum effect
- Replace bulb if bulb does not hold suction (e.g. perforation, lack of seal)
- Strip the drain (to remove debris that may be obstructing flow)
- Secure the drain at skin entry site with non-dominant hand (ensuring it does not displace)
- Exercise caution to avoid dislodging the drainage tube
- If drainage tube is dislodged, do NOT attempt reinsertion
- Start at the skin end of drain tubing
- Apply Alcohol swab folded over the tubing (lubricating jelly may be used as an alternative)
- With dominant hand, squeeze the tubing (with interposed Alcohol swab) between thumb and index finger
- Slide your fingers with the Alcohol swab along the tubing toward the collection bulb
- Repeat the procedure until no further debris is visualized in the collection tubing
- Secure the drain at skin entry site with non-dominant hand (ensuring it does not displace)
- Consider drain removal if output consistently <30 ml/day
- See below
- Discuss with surgical team if available
V. Management: Surgical Drain Removal
- Indications
- Consistently <30 ml/day output for at least 24 hours AND
- Other causes of low output drain are excluded (see above) AND
- Surgical team agrees with removal (if available for Consultation)
- Contraindications
- Active infection with persistent fluid collection (e.g. abscess)
- Consider imaging (e.g. CT) to evaluate residual fluid pocket and tube positioning
- Consult surgery or Intervention Radiology for additional management
- Active infection with persistent fluid collection (e.g. abscess)
- Benefits
- Removal of non-functioning drains reduces risk of infection, pain and ADL barriers
- Technique
- Position patient to minimize tension or Muscle resistance at drain entry site
- Cut and remove Sutures securing drain
- Release collection bulb suction
- Apply gauze (e.g. folded 4x4 pad) to the drain entry site at skin
- Apply gentle pressure with one hand to the gauze throughout drain removal
- Remove the drain
- Use slow, steady force to remove drain
- Have patient try to relax if resistance is met
- Stop if significant resistance is met
- Consult surgery for possible adhesion to deeper tissue
- Apply dressing to the drain entry site
- Anticipate some small continued drainage at the entry site for 1-2 days
- Significant drainage (e.g. higher volume, pustular) should prompt return or reevaluation by surgeon
- Complications of drain removal
- Retained Foreign Body
- Seroma development
