Background and Objective: Percutaneous central venous cannulation is a common invasive procedure. In comparison with an external landmark technique, the advantages of ultrasound-guided venous access include direct visualization of the anatomy and in vivo visualization of venous cannulation. Methods: We evaluated an ultrasound-guided technique for infraclavicular axillary vein cannulation, focusing on its ease of use, success rate and complications rate. One hundred and twenty patients who submitted to central venous catheter placement were punctured using our technique. The patients were positioned so that their ipsilateral upper limb was abducted at 90˚ to the longitudinal axis, which makes it possible to visualize the infraclavicular vessels due to the elevation of the clavicle, thereby improving accessibility. Results: Cannulation was successful in all patients. The median time from the start of the first puncture (of the skin) until the aspiration of blood was 15 s (range 7 -135 s). Both infraclavicular axillary veins were cannulated, and the vein was punctured successfully at the first attempt in 95% of the patients, without complications during the procedure. Conclusion: We propose an ultrasound-guided infraclavicular approach of the axillary vein, with a high success rate and no complications in the present cohort.

RESUMENObjetivo: Comparar la eficacia y seguridad de la anestesia tópica-subconjuntival con la retrobulbar en la escleroctomía profunda no penetrante suplementada con 5-FU. Método: Se realizó un estudio prospectivo y aleatorizado de 30 pacientes consecutivos a los que se les practicó anestesia tópica-subconjuntival (n=14) o retrobulbar (n=16). Se evaluaron las condiciones operatorias, el confort del paciente, el dolor postoperatorio, el dolor total y el resultado quirúrgico en cuanto a bajada de presión intraocular. Resultados: No hubo diferencias en las condiciones quirúrgicas entre ambos grupos. El grupo con anestesia retrobulbar refirió más dolor durante la aplicación del anestésico (P= 0,00). El grupo con anestesia tópica-subconjuntival refirió más disconfort intraoperatoriamente (P=0,00). Sin embargo, esto no representó un problema para el cirujano. No hubo diferencias en el dolor postoperatorio entre ambos grupos. No hubo diferencias estadísticamen-te significativas en cuanto al dolor total. No hubo ARTÍCULO ORIGINAL ABSTRACT Purpose: To compare the safety and efficacy of topical plus subconjunctival versus retrobulbar anesthesia for primary non-penetrating sclerectomy supplemented with adjuntive 5-FU. Methods: A prospective study of 30 consecutive patients who were randomized to receive subconjunctival (n = 14) or retrobulbar (n = 16) anesthesia was performed. Operating conditions, patient comfort, postoperative pain, total pain and surgical outcomes were evaluated. Results: There were no differences in the operating conditions. The retrobulbar group reported significantly more pain during administration of the anesthetic agent than the subconjunctival group (P= 0.00). The subconjunctival group reported more discomfort during surgery than the retrobulbar group (P= 0.00); however, this feature was not a problem for the surgeon. No statistically significant differences were found in regard to the total pain experienced, the postoperative pain, nor the success rates of the operative procedure in either group.

RESUMENCaso clínico: Presentamos el caso de un paciente varón de 73 años que desarrolló un síndrome de efusión uveal en su ojo derecho un año después de cirugía de catarata. Tras descartar posibles condiciones asociadas, se llegó al diagnóstico de síndro-me de efusión uveal espontáneo. Con un tratamiento esteroideo sistémico adecuado, el cuadro presentó una respuesta favorable. Discusión: El diagnóstico de efusión uveal puede ser difícil de establecer. Para el diagnóstico y manejo de estos pacientes, se debe realizar un examen clínico detallado, junto con angiografía fluoresceí-nica (AFG), ultrasonografía, biomicroscopía ultrasónica (BMU) y resonancia magnética nuclear (RMN).Palabras clave: Efusión uveal espontánea, flujo transescleral, desprendimiento coroideo, biomicroscopía ultrasónica. COMUNICACIÓN CORTA ABSTRACTClinical case: This was a 73 year-old male patient who developed an apparent uveal effusion syndrome in his right eye one year after cataract surgery. Once possible associated conditions were discarded, a diagnosis of spontaneous uveal effusion syndrome was reached. With appropriate systemic steroid therapy, a favourable response occurred. Discussion: The diagnosis of uveal effusion may sometimes be difficult to establish. In order to diagnose and manage these patients, a detailed clinical examination along with fluorescein angiography, ultrasonography, ultrasound biomicroscopy (UBM) and magnetic resonance imaging (MRI) tests, must be carried out (Arch Soc Esp Oftalmol 2007; 82: 505-508).
