Presentation Transcript

  1. Prevention of Sepsis • Handwashing • Skin preparation • Tissue Handling • Minimise trauma • Avoid damage to blood vessels • Minimise blood loss • Obliterate dead space • Minimise foreign material • Antibiotic prophylaxis

  2. Surgical Drains • Indications: • Prevent accumulation of fluid • Blood • Pus • Infected fluids • Prevent accumulation of air/gas • Characterise fluid

  3. Surgical Drains • Types: • Open • Simple (corrugated tubes or sheets) • Can increase the risk of infection in non-infected cases • Closed • Reduce the risk of infection • Passive • Differential pressure or gravity • Active • Suction - low or high pressure (Redivac) • Rubber • Inflammatory - may encourage tract formation • Silastic • Inert

  4. Surgical Drains • Types • Penrose • Soft rubber tube • Dependent Drainage - gravity • Open • Jackson-Pratt • Closed • Collection bulb + low grade suction • Negative Pressure Wound Therapy • Enclosed foam + suction • Healing of large areas by granulation

  5. Surgical Drains • Practical Points • Drain must be secured (but removable) • Fluid drained must be measured (accurately) • Include fluid drained in fluid balance • Monitor changes in character of fluid drained

  6. Surgical Drains • Removal • Always use aseptic technique • As soon as possible • The longer in situ, the greater the risk of infection • When drainage < 25 ml/day • Shortening - gradual removal • Useful when draining part of the body that normally secrete fluid, e.g. peritoneum. • Analgesia may be needed • Send tip to lab. for culture, if available

  7. Surgical Drains • Evidence • Paucity • Remember: No evidence of effect is NOT the same as evidence of no effect. • Not recommended in uninfected or uncomplicated cases. • In complex cases, understand the problem and the benefits to be gained by using a drain. • Remove as soon as possible when job done to avoid introducing infection.

  8. Any Questions?

  9. Bacteriology Samples • Time of pyrexia • Pre-antibiotics • Sample taken properly (aseptic technique) • Specimen to lab ASAP (particularly anaerobes) • Swabs in transport media • Label correctly
