  Purpose

Infiltration of a local anesthetic into the surgical wound is a simple method to strive to control postoperative pain after surgery. In the investigators institution, this method is used quite often. However, there is a controversy regarding the analgesic efficacy. Moreover, the cost of the single use elastomeric pump used with this procedure is clearly higher than the costs of other routinely used analgesic methods.

According to the investigators observations, infiltration of a local anesthetic into the surgical wound after caesarean section seems to reduce the need for rescue analgesics. However, the scientific evidence of the efficacy of this technique is weak. The investigators decided to conduct a prospective, controlled, randomised, double blind trial on this topic.

The hypothesis is that wound infiltration with local anesthetic will reduce postoperative pain and opioid consumption after caesarean section without major adverse effects.

Primary Outcome Measures:
  • The demand of rescue analgesics [ Time Frame: 48 hours ]
    The amount of opiate analgesics requied 48 hours after operation. Rescue analgesics will be administred when the strength of pain is over 3 on numeric rating scale (NRS) 0-10.


Secondary Outcome Measures:
  • Strength of pain on numeric rating scale (NRS) [ Time Frame: 48 hours ]
  • Postoperative nausea and vomiting (PONV) [ Time Frame: 48 hours ]
    The vigor of nausea will be assessed on the numeric rating scale (NRS) 0-10. NRS values over 3 will be medicated with antiemetics.
