True statement regarding Bupivacaine is 
Select and explain. 
A. Used as intravenous along with lignocaine, B. More cardiotoxic than lignocaine, C. Contraindication in pregnancy, D. All of the above
B: More cardiotoxic than lignocaine
Answer: B: More cardiotoxic than lignocaine 
Explanation: (More cardiotoxic than Lignocaine)(326-KDT) (357-KDT6th)BUPIVACA1NE - long acting amide linked LA used for infiltration, nerve block, epidural and spinal anaesthesia of long duration* A 0.25-0.5% solution injected epidurally produces adequate analgesia without significant motor blockade. As a result it has become very popular in obstetrics (mother can actively cooperate in vaginal delivery).* ** Bupivacaine is more prone to prolong QTc interval and induce ventricular tachycardia or cardiac depression-should not be used for intravenous regional analgesia. (UP-2010)* It should not be used for Beir block (because of its cardiotoxicity)* Drug of choice for ventricular tachycardia produced by bupivacaine is bretylium
