Ropivacaine is a member of the amino amide class of local anesthetics and is supplied as the pure S-(-)-enantiomer. Local anesthetics block the generation and the conduction of nerve impulses, おそらく神経の電気的興奮の閾値を高めることによって, 神経インパルスの伝播を遅らせることによって, そして活動電位の上昇速度を低下させることによって. 一般的に, the progression of anesthesia is related to the diameter, myelination and conduction velocity of affected nerve fibers. 臨床的に, the order of loss of nerve function is as follows: 痛み, temperature, touch, proprioception, and skeletal muscle tone.
(1) Surgical anesthesia:Epidural anesthesia (including epidural anesthesia during cesarean section);Local infiltration anesthesia.
(2) Acute pain control:For postoperative or labor analgesia continuous epidural infusion can be used can also be intermittent medication;Local infiltration anesthesia.
