ABSTRACT
BACKGROUND: Intravenous remifentanil may be the preferred analgesic when regional techniques are contraindicated. OBJECTIVE: To perform a systematic review on the use of remifentanil for analgesia in labor. METHODS: We searched MEDLINE (January 1995-August 2007) for studies on obstetric analgesia with remifentanil. RESULTS: We found 32 references representing the use of remifentanil in 257 women in labor. In most cases, patients reported relief of pain and a high level of satisfaction, with no severe side effects in mothers or neonates. When compared with meperidine and nitrous oxide in clinical trials, remifentanil provided better analgesia with fewer adverse effects. CONCLUSION: Analgesia with intravenous remifentanil is more effective and safer than other alternatives to regional analgesic techniques in obstetrics. Nevertheless, the optimum system for infusing the drug must b e established and further studies of maternal and fetal safety should be carried out.

Cancellation of scheduled surgery is undesirable for patients and an inefficient use of resources. We prospectively collected data for 52 consecutive months in a public general hospital to estimate the prevalence and causes. The overall cancellation rate was 6.5% (2559 of 39 115 scheduled operations). Cancellation by broad category was for 'medical reasons' in 50%, 'patient-related factors' in 23%, and due to 'administrative/logistic problems' in 25%. The commonest specific causes within these categories were respectively: infections/fever (18%), patient did not attend (20%) and lack of theatre time (23%). This data will help direct resources to target prevention of cancellations as a result of these main problems.

La analgesia con remifentanilo intravenoso podría serla primera alternativa a las técnicas regionales cuandoéstas se encuentran contraindicadas.OBJETIVO: Revisión sistemática de la bibliografía disponiblesobre el uso de remifentanilo como analgesia delparto. Método: Búsqueda en MEDLINE (enero 1995-marzo 2009) y revisión de bibliografía de las publicacionessobre la analgesia obstétrica con remifentanilo.RESULTADOS: Se encontraron 37 referencias con untotal de 281 embarazadas tratadas con remifentanilo. Enla mayoría de los casos las pacientes mostraron descensoen el dolor referido y alto grado de satisfacción, sinefectos secundarios graves en las madres o neonatos.Comparándolo en ensayos clínicos con meperidina y óxidonitroso, el remifentanilo obtuvo mejores resultados enanalgesia y menores efectos secundarios.CONCLUSIÓN: La analgesia con remifentanilo intravenosoes una alternativa más eficaz y segura que otras técnicasno regionales en la analgesia obstétrica. Aún debeestablecerse el sistema óptimo de administración y se precisanestudios más amplios de seguridad materno-fetal(AU)
