Resumo

Cette observation rapporte le cas d'une rachianesthésie totale compliquant un bloc du plexus lombaire par voie postérieure, effectué en phase postopératoire d'un remplacement prothétique de hanche réalisé en L4 avec neurostimulateur, sans signe d'effraction de la dure-mère ni signe vasculaire immédiat (reflux absent et dose test négative). Cette éventualité impose une injection lente et fractionnée de la solution anesthésique lors de la réalisation des blocs du plexus lombaire. We report a case of total spinal anaesthesia which occurred after a lumbar plexus block using a posterior approach. After total hip arthroplasty under general anaesthesia, a lumbar plexus block was performed according to Winnie's landmarks at the L4 interspace using a nerve stimulator. Aspiration test for blood and spinal fluid were both negative, as well as a test dose of 3 mL lidocaine 2 %-bupivacaine 0.5 %. One minute after the injection of 27 mL of the same mixture, a complete anaesthetic block occurred with hypotension and loss of consciousness requiring intubation and controlled ventilation during 3h30, without sequelae. Lumbar plexus block using a posterior approach must be performed cautiously and a slow and fractionated injection of the full dose is recommended.
