  Purpose

Pre-emptive local anaesthetics are widely used in laparoscopic surgery, but there is no really consistent evidence that it is useful. Studies in the literature have shown contradicting results. At our hospital we are currently using pre-emptive local anaesthetics in the trocar areas, but as the literature does not give a clear and clinically relevant answer, we need to find out more. This study aims to see if pre-emptive local anaesthetics are useful in the setting of our day-case, laparoscopic surgery.

Primary Outcome Measures:
  • Postoperative movement-evoked pain [ Time Frame: 5 hours postoperative ] [ Designated as safety issue: No ]
    The primary outcome of the study will be movement-evoked pain (MEP) 5 hours after surgery, as half-life of bupivacaine is 4-6 hours. Movement-evoked pain is the most important outcome measure, because the goal is to get the patient back to normal, daily activities as soon as possible.


Secondary Outcome Measures:
  • Pain at rest [ Time Frame: 2 and 5 hours postoperative ] [ Designated as safety issue: No ]
    Secondary outcome measures will be pain at rest at 2 and 5 hours postoperative.

  • Rescue analgetics [ Time Frame: 5 hours postoperative ] [ Designated as safety issue: No ]
    Use of rescue analgesics postoperative.
