Brief Summary:
To evaluate the effects of bilateral dual transversus abdominis plane block on postoperative pain after robotic assited laparoskopic surgery and measure the plasma-level of ropivacain after the bilateral dual transversus abdominis plane block.

Condition or disease Intervention/treatment Phase
Pain Treatment Robotic Assisted Laparoscopic Surgery Bilateral Dual Transversus Abdominis Plane Block Drug: Ropivacaine Drug: Isotonic potassium chloride Not Applicable

Detailed Description:

After randomisation patients for robotic assisted laparoscopic surgery will receive bilateral dual transversus abdominis plane block containing either ropivacain or isotonic potassium chloride.

The investigators will record pain-score, opioid-consumption and sensibility on the abdominal wall in the postoperative periode.

Also a blood sample will be taken at 15, 30, 60, 120 and 240 minutes after the block in order to measure the plasma-level of ropivacain after bilateral dual transversus abdominis plane block.

The investigators assume that there will be significant effect on postoperative pain and that the level of plasma-ropivacain will be acceptable.
