ABSTRACT

Se realizó un estudio de tipo ensayo clínico-terapéutico, comparativo y prospectivo, aleatorizado y a ciegas, para evaluar la eficacia de la clonidina de producción nacional por vía intratecal en combinación con otros agentes, para el alivio del dolor posoperatorio (PO) y describir los efectos adversos atribuibles a su uso. Se seleccionaron a 100 pacientes programados para cirugía proctológica. Se conformaron 4 grupos de 25 casos: lidocaína hiperbárica (G-1), lidocaína hiperbárica más fentanyl (G-2), lidocaína hiperbárica más clonidina (G-3), lidocaína hiperbárica más fentanyl más clonidina (G-4). El tiempo de analgesia PO más prolongado se logró en G-4, también en él ningún paciente refirió dolor severo. El tiempo de analgesia menor se encontró en G-1, así como la mayor cantidad de pacientes con dolor severo. La hipotensión transoperatoria y la retención urinaria PO fueron los efectos adversos más frecuentes, aunque no significativos(AU)


A clinicotherapeutic comparative and prospective randomised blind study was conducted to evaluate the efficacy of clonidine of national production administered by intrathecal route in combination with other agents to relieve postoperative pain (PP) and to describe the adverse effects attributable to its use. 100 patients that were scheduled to undergo proctological surgery were selected and divided into 4 groups of 25 cases each: hyperbaric lidocaine hydrochloride (G-1), hyperbaric lidocaine hydrochoride plus fentanyl (G-2), hyperbaric lidocaine hydrochloride plus clonidine (G-3), and hyperbaric lidocaine hydrochloride plus fentanyl plus clonidine (G-4). The longest analgesia time (AT) was attained in G-4 and no patient had acute pain in this group. The lowest analgesia time was found in G-1 , as well as the highest number of patients with acute pain. Transoperative hypotension and postoperative retention of urine were the commonest adverse effects, although they were not significant(AU)
