Bloqueo continuo del grupo de nervios pericapsular como analgesia para fractura de columna y pared posterior de acetábulo, reporte de caso y descripción de régimen de infusión para ampliar la cobertura analgésica a la región femoral distal / Continuous pericapsular nerve group blockade as analgesia for fracture of the posterior column and wall of the acetabulum; a case report and description of infusion regimen for extending analgesic effect to the distal femoral area

El uso de bloqueos de nervios para cirugías de cadera tiene beneficios demostrados. El bloqueo del grupo de nervios pericapsular es una técnica nueva que ha demostrado proveer una analgesia más satisfactoria para fracturas y artroplastias de cadera, en comparación con otros bloqueos más comúnmente usados para este tipo de cirugía. Este permite bloquear la inervación de la cápsula anterior a través del nervio obturador y las ramas articulares del femoral y obturador accesorio. Existen escasas publicaciones que describan el uso de catéteres perineurales para proveer analgesia continua utilizando esta técnica. Presentamos un caso de bloqueo continuo para analgesia preoperatoria, en un paciente que sufrió una fractura de columna y pared posterior de acetábulo, por aproximadamente 120 h. Al aumentar la velocidad de infusión se logró agregar analgesia para la región femoral distal. A diferencia de lo descrito previamente, el bloqueo se realizó utilizando un transductor de ultrasonido lineal

The use of peripheral nerve blockade for hip surgeries has proved to be beneficial. The PEricapsular Nerve Group block is a new technique described for hip fracture and hip arthroplasty that has shown to provide better analgesia compared to other peripheral blocks commonly performed for this type of surgery. This technique blocks the obturator nerve and the articular branches of the femoral nerve and the accessory obturator nerve. There are few reports describing continuous analgesia using catheters inserted in the pericapsular nerve group area. We describe a case of continuous nerve block for preoperative analgesia that lasted up to 120 hours in an adult patient with a fracture of the posterior column and wall of the acetabulum. We found that by increasing the infusion rate, analgesia reached the distal femoral area. Unlike the original technique, a high-frequency linear probe was used in this case
