True statement regarding Bupivacaine is:
Used intravenously along with lignocaine
More cardiotoxic than lignocaine
Contraindicated in pregnancy
All of the above
Bupivacaine is more cardio toxic than Lignocaine as it more prone to prolong QTc interval and induce ventricular tachycardia or cardiac depression- should not be used for intravenous regional anesthesia. It has high lipid solubility: distributes more in tissues than in blood after spinal or epidural injection . Therefore less likely to reach foetus. Hence used widely in obstetrics .
