To evaluate the analgesic efficacy of ultrasound-guided erector spinae plane blockade (ESPB) at lumbar level with ropivacaine 0.2 % (2 mg/ml) in the control of postoperative pain during 24 hours in patients undergoing lumbosacral surgery compared to ESPB performed with ropivacaine 0.3 % (3 mg/ml) and ESPB performed with Physiological Serum 0.9 %. |
Evaluar la eficacia analgésica del bloqueo ecoguiado del plano del músculo erector de la columna (ESPB) a nivel lumbar con ropivacaína 0.2 % (2 mg/ml) en el control del dolor postoperatorio durante 24 horas en pacientes sometidos a cirugía lumbosacra comparado con ESPB realizado con ropivacaína 0.3 % (3 mg/ml) y ESPB realizado con Suero Fisiológico 0.9 %. |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate: • The intraoperative analgesic efficacy of ESPB • The use of ESPB to reduce the total intraoperative remifentanil dose. • The use of ESPB in the reduction of perioperative complications derived from the use of opioids. • The safety of the technique in the form of perioperative adverse events. • The usefulness of ESPB in early mobilisation without postoperative pain in patients who underwent lumbosacral spine • The sensory level achieved by performing the block at the L3 level. • A possible association between ESPB with the appearance of motor or sensory alterations at the lower limb level. - To determine: • The concentration of ropivacaine (0.2 % vs. 0.3 %) at which analgesic efficacy is achieved during the first 24h. • The level of patient satisfaction with the anaesthetic technique. |
- Evaluar: • La eficacia analgésica intraoperatoria del ESPB. • El uso del ESPB para reducir la dosis total de remifentanilo intraoperatorio. • El uso del ESPB en la reducción de complicaciones perioperatorias derivadas del uso de opioides. • La seguridad de la técnica en forma de eventos adversos perioperatorios. • La utilidad del ESPB en la movilización precoz sin dolor postoperatorio de los pacientes intervenidos de columna lumbosacra. • El nivel sensitivo alcanzado con la realización del bloqueo a nivel de L3. • Una posible asociación entre ESPB con la aparición de alteración motora o sensitiva a nivel de miembros inferiores. - Determinar: • La concentración de ropivacaína (0.2 % vs 0.3 %) a la que se consigue eficacia analgésica durante las primeras 24h. • El nivel de satisfacción del paciente con la técnica anestésica. |
