Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of propacetamol and morphine in postoperative analgesia].
To compare the analgesic efficacy and tolerance of propacetamol and morphine, 80 patients in good clinical condition were included in a prospective, parallel, randomized double blind trial after elective surgery expected to elicit light to moderate postoperative pain. At the end of general anesthesia, 40 patients received 30 mg/kg propacetamol and 40 0.2 mg/kg morphine, as a 15-min intravenous infusion. The groups were similar for age, weight and duration of anesthesia. ⋯ No significant differences were observed in blood oxygen saturation, blood pressure, heart rate, body temperature and vigilance evaluated by the trailmaking test. Nausea was present in 4 cases under propacetamol and 3 under morphine, and pruritus in 2 and 7 cases, respectively. In conclusion, propacetamol may represent an alternative to morphine for pain prevention after mildly to moderately painful surgery in situations where the use of opioids is unsuitable.

Cancer pain can be effectively controlled in most patients by classical pharmacological treatment. We retrospectively studied the characteristics and factors associated with non responsive pain. Between 1989 and 1996, 1767 patients were referred to our pain center; 831 (47%) had cancer pain and from 787 evaluable cases 118 (15%) experienced non-controlled pain whereas good pain control was achieved within a few days in 669 (85%) patients. ⋯ On the other hand, diffuse pain, abdominal pain, terminal care, near death and doses of strong opioids were significantly different. Factors associated with therapeutic failure were conflicts, life and complications and breakthrough pain. In the presence of refractory cancer pain the factors predictive of therapeutic failure should be identified in order to optimize individual pain treatment.
