Abstract:
Objective To evaluate the feasibility of using lumbar plexus block for unilateral extremity artificial vascular graft between femoral artery and deep femoral artery in elderly patients.Methods Forty ASA physical status Ⅱ or Ⅲ patients,aged 67-81 yr,weighing 47-65 kg,scheduled for extremity artificial vascular graft between femoral artery and deep femoral artery,were randomly divided into 2 groups (n =20 each) using a random number table:spinal anesthesia group (group S) and lumbar plexus block group (group L).In group S,0.5 ％ hyperbaric ropivacaine 3 ml was injected into the subarachnoid space.In group L,lumbar plexus block was performed with 30 ml of 0.5 ％ ropivacaine under the guidance of a nerve stimulator.The onset time and duration of sensory block,anesthetic efficacy,and requirement for ephedrine and volume of fluid infused during operation,and development of lumbar plexus block-related adverse events were recorded.Results Compared with group S,the onset time and duration of sensory block were significantly prolonged,the requirement for ephedrine and volume of fluid infused during operation were decreased,and no significant change was found in anesthetic efficacy in group L.No lumbar plexus block-related adverse events developed in group L.Conclusion Lumbar plexus block can be used for unilateral extremity artificial vascular graft between femoral artery and deep femoral artery in elderly patients.
