Abstract
Nous recourons au bloc du plexus lombaire et du nerf sciatique pour la chirurgie unilatérale du membre inférieur. Le but de cette étude est d’évaluer la 2-chloroprocaïne (2-CP) pour la chi rurgie ambulatoire de courte durée en association avec ces blocs. Vingt-cinq patients ASA I et II participent à l’étude. Les techniques de blocs utilisées sont celles décrites par Winnie et Labat. Une dose totale de 60 ml de 2-CP 3% est injectée. Le temps nécessaire à l’apparition du bloc est d’environ sept min pour le plexus lombaire et de 14 min pour le nerf sciatique. La durée moyenne du bloc moteur est de 71 ± 16 min pour le sciatique, 76,8 ± 15,3 min pour le fémoral, 75 ± 12,7 min pour l’obturateur. Quant au bloc sensitif, la durée moyenne est de 88,7 ± 20,9 min pour le sciatique, de 83,3 ± 16,4 min pour le fémoral, de 79,7 ± 17,8 min pour l’obturateur et de 93,7 ± 22 min pour le fémoro-cutané. Le succès obtenu est de 92% et aucune complication importante n’est survenue. Nous concluons que l’association des blocs du plexus lombaire et du nerf sciatique, en utilisant la 2-CP comme anesthésique local est une technique utile pour la chirurgie ambulatoire de courte durée intéressant le membre inférieur.
Abstract
A combination of the lumbar plexus and sciatic nerve blocks using 2-chloroprocaine (2-CP) for unilateral lower extremity anaesthesia was studied. The purpose of this work was to evaluate the efficacy of 2-CP for ambulatory surgery of short duration with this combination of blocks. Twenty-five patients ASA 1 and 2 were studied. The techniques used have been described by Winnie and Labat. A total dose of 60 ml of 2-CP 3% was injected. Latency time before anaesthesia was approximately seven min for the lumbar plexus and 14 min for the sciatic nerve. The mean duration of the motor block was 71 ± 16 min, 76.8 ± 15.3 min and 75 ± 12.7 min for the sciatic, femoral and obturator nerves respectively. The mean duration of the sensory block was 88.7 ± 20.9 min, 83.3 ± 16.4, 79.7 ± 17.8 min and 93.7 ± 22 min for the sciatic, femoral, obturator and lateral femoral cutaneous nerves respectively. Success rate was 92% and no major complication occurred. We conclude that a combination of the lumbar plexus and the sciatic nerve blocks with 2-CP is a useful technique for ambulatory surgery of short duration.
