背景:有证据表明罗哌卡因导致的心脏毒性比相同剂量的布比卡因低,但布比卡因脂溶性高,且作用强度大,临床上只需较小的剂量即可.中枢神经系统明显的神经毒性作用(如惊厥)往往是心脏毒性产生的先兆,半数致死剂量和半数致惊厥剂量的比值能够反应局麻药的安全性.
BACKGROUND: It is demonstrated that ropivacaine has less toxicity than bupivacaine, but bupivacaine has higher liposolubility and efficacy, so a less dose of bupivacaine is needed in clinical comparing with ropivacaine. Serious convulsion is usually followed by cardiotoxicity induced by local anesthetics

半数致死剂量和半数致惊厥剂量的比值能够反应局麻药的安全性.目的:确定罗哌卡因、布比卡因、利多卡因的半数致惊厥剂量和半数致死量,比较在引起50%致惊厥反应率时3种酰胺类局部麻醉药对中枢神经系统的毒性作用

The ratio of medial lethal dose (CD50) and median convulsant doses (LD50) is usually used to assess the comparative safety of local anesthetics

罗哌卡因在临床麻醉中的使用剂量较少超过布比卡因,很少达到其致惊厥剂量,具有较高的安全性.但一旦发生中枢毒性反应,罗哌卡因导致的惊厥则会更加严重,It is indicated that if an accidental convulsion induced by ropivacaine, it may be more severe than that induced by correspondent either lidocaine or bupivacaine. It may be the reason that ropivacaine have less lipid solubility, absorbed easily from this tissue compartment, and to get a high concentration in blood.可能与其脂溶性低,吸收后分布容积小,血浆浓度高有关.

A physician know everything but can do nothing; a surgeon can do everything but know nothing; only the anesthetist know everthing and can do everything!
内科医师什么都懂却什么都不能做；外科医师什么都能做但什么都不懂；只有麻醉医师什么都懂而且什么都能做！

Electroshock therapy, which consists of running an electric current through a patient while under anesthetic, is administered only to those victims who are suicidal and require immediate treatment, or to those with severe refractory depression.
电疗法是将电流通过在麻醉状态下的患者，实施的对象仅限于有自杀之虞、需要立即治疗者，或是严重到难以医治的忧郁症患者。
