Postoperative pain and analgesic treatment still remains a challenge in daily perioperative medicine. Skin incisions, intraoperative tissue retraction and -dissection, intravasal cannulations and drainages, sternotomy and pericardiotomy are the most important reasons for postoperative pain. Poorly controlled pain can contribute directly or indirectly to postoperative complications, such as myocardial ischemia, pulmonary dysfunction like hypoventilation, pneumonia and atelectasis, a delayed return of gastrointestinal function and decreased mobility. In addition, prolonged acute pain also results in chronic pain.

Opioids are internationally recognized as the golden standard in the treatment of acute postoperative pain. On one side, the high potency of opioids in pain relief is clearly undisputed, but on the other hand, the administration of opioids is associated with nausea, vomiting, sedation and with the development of bowel dysfunction, which encompasses symptoms including bloating, abdominal spasm, cramps and constipation. Opioid-induced constipation is a frequently reported adverse effect and sometimes requires discontinuation of therapy, which results in analgesic under-treatment, severely impairing quality of life. However, there are many different regimes for the treatment of postoperative pain using opioids. Patient-controlled analgesia (PCA) using morphine is widely used, but requires trained staff and expensive equipment. Once patients are able to tolerate oral medications, the oral route is preferred postoperatively because it is more convenient, noninvasive and less expensive.

Arms Assigned Interventions
Active Comparator: Targin/OxyNorm
Patients randomized to this study arm will receive Targin as basis pain medication and additional OxyNorm (Oxycodone), if requested by the patients.
Drug: Targin
Other Name: Oxycodonhydrochlorid and naloxone hydrochloride dihydrate
Drug: Oxynorm
Other Name: oral medication consisting of Oxycodonhydrochlorid
Active Comparator: PCA
Patients randomized to this group will receive a PCA pump with morphine. The basic rate is 0.3 mg/h. Patients will be allowed to administer 1 mg each five minutes after a vesting period of five minutes, if subjectively needed.
Drug: Morphine
