title: [Critical reevaluation of cyclooxygenase two inhibitors in perioperative pain therapy].
abstract: A significant increase in thromboembolic events (i.e. myocardial infarction and stroke) was demonstrated in multicenter studies after several months of treatment with cyclooxygenase 2 (cox-2) inhibitors. In February 2005, the European medical agencies (EMEA) substantially increased the number of contraindications for all cox-2 inhibitors. They are now contraindicated for patients with coronary artery disease. Furthermore, 2 out of 6 cox-2 inhibitors have been withdrawn from the market. In this review, the current state of knowledge on the use of cox-2 inhibitors in perioperative pain therapy is summarized: i) they are equally as potent as other non-opioid analgesics, ii) they decrease opioid consumption, iii) a reduction in postoperative nausea and vomiting (PONV) has not been adequately demonstrated. Regarding side-effects, it can be concluded that i) the incidence of thromboembolic events is increased in patients undergoing coronary artery bypass surgery, ii) perioperative blood loss is not affected, iii) ulcer formation is not promoted, iv) the risk for acute renal failure is probably increased to the same extent as for NSAIDs and v) severe bronchospasm can be triggered in patients with asthma and chronic obstructive pulmonary disease (COPD).
