[Supraclavicular plexus blockade using prilocaine in patients with chronic anemia].
It has not yet been clarified whether prilocaine-induced methemoglobinemia is a problem in patients with chronic anemia. We therefore performed supraclavicular brachial blockade for upper limb surgery (6 mg/kg prilocaine 2% + 0.1 IU vasopressin/ml) in ten female patients with chronic renal failure (mean Hb 8.19%) requiring hemodialysis. Before the blockade, a catheter was inserted into the opposite internal jugular vein and blood samples were drawn before and 10, 15, 20, 30, 45, 60, 90, 120 and 180 min after injection. Plasma prilocaine concentrations and methemoglobin levels were within the ranges measured by other authors in healthy patients. There was no correlation between plasma prilocaine levels and methemoglobinemia. We therefore consider prilocaine to be a safe local anesthetic in patients with renal failure and chronic anemia.
