The disadvantages of the peridu-ral technique in an urgent setting include prolonged latency time for the onset of action and inadequate blockade, higher rates of intraoperative pain and the need to add systemic agents and/or convert to a different anaesthetic technique.Another option is to use combined peridural-spinal techniques, which have the advantage of the profound block of the spinal technique plus the probability of anaesthetic support of the peridural catheter in the event the procedure is prolonged.
Otra opción es administrar una técnica peridural; sus desventajas en los escenarios urgentes están dadas por tiempo prolongado de latencia para su instauración y un bloqueo inadecuado, mayor tasa de dolor intraoperatorio y necesidad de suplementar con agentes sistémicos y/o pasar a otra técnica anestésica.
