CONTINUOUS WOUND INFUSION

Continuous Wound Infusion (CWI) is a technique which uses a multi-holed catheter to deliver local anaesthetics or analgesics directly into the wound for postoperative pain relief.
It can be used as a single technique or as part of a multi-modal analgesic approach.

  • Effective Postoperative Analgesia
    The continuos wound infusion of local anaesthetics or analgesics has benn proven to provide effective postoperative analgesia for patients undegoing abdomina, gynecological1, thoracic 2-3 and orthopaedic surgeries4 – 7 as well as C section8 and hernia. 9
  • Reduces Opioid Usage
    Continuous wound infusion reduces the need for systemic opioids in the postoperative period.1 – 9
  • Safe Technique
    Continuous infusion of local anaesthetics or analgesics in the surgical wound for postoperative analgesia is a safe technique as it does not increase
    the number of wound infections5 – 7 – 8, does not impair the wound healing process 5 – 7 – 8, and does not generate toxic levels of local anaesthetics in the patient’s plasma.1-5-7-8
  • Reduces Hospitalisation
    Some studies found that continuous wound infusion can reduce a patient’s lenght of stay in hospital.1 – 2 – 5
  • Excellent Patient Satisfaction
    Contnuous wound infusion for postoperative analgesia provides excellent patient satisfaction. 5 – 6 – 8

  • Radioopaque catheter with advanced design feature
    to optimise uniform flow distribution
  • High tensile strength
    indicating low risk of breakage10
  • Convenient, easy to use system
    with peel-away Introducer needle, dressing and catheter fixation
  • Range of 19 gauge catheters
    to cover various incision lengths
  • Markings
    to allow identification of multi-holed section, distance from the beginning of the multi-holed section and catheter integrity
  • Preconnected hub and hub sleeve
    minimise the risk of disconnection or kinking after removal
