羅哌卡因

用途

• Analgesia (perineural, epidural, or intrapleural)
• Analgesia

給藥方式

可能的副作用

• Cardiac arrhythmias (if injected intravascularly)
• Systemic toxicity (CNS excitation followed by depression, seizures)
• Motor blockade (dose-dependent)

注意事項與禁忌

• Intravenous (IV) administration
• Intravenous regional anaesthesia (Bier block)
• > **Strictly avoid intravenous injection.** Inadvertent intravascular injection may precipitate cardiac arrhythmias that are refractory to treatment. * **Aspiration:** Always aspirate prior to injection to ensure the needle is not in a blood vessel. * **Systemic Absorption:** Lower doses should be used when systemic absorption is likely to be high (e.g., intrapleural analgesia). * **Dilution:** Small volumes can be diluted with normal saline to enable wider distribution for perineural blockade.

藥物相互作用

• Other local anaesthetics: Additive systemic toxicity; dose of ropivacaine should be reduced when used in combination.
• Adrenaline (Epinephrine): Unlike some other local anesthetics, the addition of adrenaline does not appear to significantly alter the duration of the ropivacaine block.
