ABSTRACT

Popliteal sciatic block is considered a good alternative analgesia for performing leg, ankle or foot’s fracture reduction at an emergency room. We hypothesized that performing the procedure in prone position rather than supine is better tolerated by the patients. Since 1995, we have used popliteal sciatic block carried out in both positions. Our study consists in 507 patients with fractures of the involved segment of the lower limb who presented at the emergency room from 1998 to 2008. All of them were treated with closed reduction and immobilization under popliteal sciatic block analgesia. The Procedure was performed by orthopedic surgeons guided by an anesthesiologist. 22.5 ml of lidocaine at 1.33 percent was used for obtaining paresthesia. Pain outcome was evaluated using the Visual Analog Scale (VAS) and by patient and surgeon questionnaire. Patient and surgeon’s satisfaction was 90 percent and 94 percent, respectively. Our series reports a simple, reliable and safe analgesia technique for closed fracture’s reduction of the lower limb at the emergency department.


Para reducciones de fracturas de pierna, tobillo y pie generalmente basta un bloqueo ciático, que realizado en la posición prona, produce dolor e incomodidad al paciente. Desde el año 1995 utilizamos en nuestro hospital el bloqueo poplíteo vía posterior en posición supina para estos procedimientos. Se analiza la experiencia de 10 años con 507 pacientes con lesiones del segmento a los cuales se les practicó reducción de su fractura con bloqueo poplíteo realizado por residentes de Ortopedia y Traumatología capacitados y supervisados por anestesiólogos. Se utilizó lidocaína 22,5 ml al 1,33 por ciento obteniéndose parestesias. La evaluación se realizó mediante escala EVA y encuesta al operador y paciente. El 90 por ciento de los pacientes y el 94 por ciento de los operadores dan una evaluación positiva del procedimiento. La técnica siendo simple, confiable y segura proporciona una excelente anestesia para reducciones de la extremidad inferior.
