ACIN, P. et al. Stability of parecoxib in dilution with other drugs and administered in continuous intravenous infusion for the management of postoperative pain. Rev. Soc. Esp. Dolor [online]. 2007, vol.14, n.3, pp.185-193. ISSN 1134-8046.

Objective: To evaluate the stability of parecoxib in a portable elasto-meric pump system for IV infusión in dilution with opioids (morphine chloride, pethidine or tramadol), antiemetics and saline solution during 24 hours in the postoperative period; as well as to verify the analgesic result, the incidence of side effects and the degree of satisfaction in patients undergoing major surgery that were eligible for treatment with these drugs. Material and Methods: The infuser pump is a light disposable device with an elas-tomeric deposit to administer the medication. Several tests combining parecoxib, opioids, antiemetics and saline solution were carried out and its stability was demonstrated during 24 hours. The mixture was then observed in several occasions and was shown that the dilution always remained stable, clear, with no particles and transparent; therefore it was decided to use that combination in the IV infuser for the treatment of postoperative pain, always under the anaesthesiologist supervisión. A total of 118 patients were studied, 46 women (39%) and 72 men studied (61%), ASA ITV, mean age 59.75 +/- 14.25 (18-89); 92 (78%) underwent general surgery procedures and 26 (22%) urologic ones. The filling of infuser according to ASA, age and type of surgery of the patient, was made with: parecoxib 80 mg + metoclopramide CL H 20 or 30 mg + saline solution for the 118 patients, morphine chloride was added in 65 patients, petidine in 30 and tramadol in 23, during 24 hours after surgery. Pain was assessed using a VAS in both at arrival in the PACU and 24 hours after the surgical procedures. Analgesic outcome, side effects and degree of satisfaction were re-corded. Results: The analgesic outcome was very good in 60 patients (50.85%); good in 40 (33.90%); regular in 12 (10.17%) and the treatment was interrupted 6 (5%) due to side effects. Side effects were present in 30 (25%) cases: 4 with perspiration (3%), 1 with disorientation (0.8%) and 7 with somnolence and dizziness (6%) 3 of them with interruption of the treatment. For nausea and vomiting, 18 patients needed antiemetics res-cue, and in 3 cases it was necessary to suspend the treatment. The degree of satisfaction reported by patients was: very satisfactory in 56 patients (47.5%); satisfactory in 46 (39%), inadequate in 10 (8.5%) and the treatment was suspended in 6 (5%) due to side effects. Conclusions: The possibility of using parecoxib alone or in combination with other drugs in continuous IV perfusión for acute postoperative pain is an important option to be considered.
