Zusammenfassung
Trotz einer Vielzahl von Therapieoptionen wird die Akutschmerztherapie nach onkologischen
Operationen häufig als unzureichend beschrieben. Neben einer unzureichenden Akutschmerztherapie
können weitere Faktoren eine Hypersensitivierung und Chronifizierung sowie den Verlauf
der Tumorerkrankung beeinflussen. Dieser Beitrag erklärt pathophysiologische Hintergründe
und erläutert geeignete Therapiemodalitäten.
Abstract
Due to preexisting pain or surgically induced sensitization patients undergoing oncological
surgery are predisposed for a postoperative high pain intensity with the risk of developing
persistent pain. In oncological surgery, pain therapy should be adapted to the underlying
pain mechanism. Different treatment principles should be applied in a graded concept
of acute pain therapy. The rationale implies the “conventional” use of the WHO step
scheme, the administration of opioids as PCA as well as regional analgesia and agents
with anti-hypersensitizing properties. Anti-hypersensitizing and anti-neuropathic
treatment principles may include the use of antidepressants, anticonvulsants, intravenous
lidocaine and s-ketamine. Before using such treatment, pain mechanisms should be verified
by an adequate pain diagnostic. The impact of perioperative regional analgesia on
the oncological outcome is subject to controversy. Opioids reveal both: tumor promoting
and tumor inhibiting properties.
