Midline laparotomy is commonly used in emergency and elective cancer surgery and patients need effective and safe pain treatment after this type of surgery. Nowadays modern anticoagulant therapy may prevent use of central regional blocks in pain management. Therefore in the present study the efficacy and safety of rectus sheath analgesia is studied using different administration techniques. The primary aim is the efficacy of the rectus sheath analgesia measured with pain ratings and the amount rescue opioid used.

Secondary aims were concentrations of local anesthetic, rescue opioid and satisfaction to analgesia method used.
