Question of the Day

An otherwise healthy 25-year-old G1P0 is taken emergently to the OR for cesarean delivery. She receives a bolus of 30 mL of 2-chloroprocaine through an existing epidural catheter. Which of the following is MOST correct regarding the use of 3% 2-chloroprocaine?

Question of the Day


2-Chloroprocaine is considered a safe and favorable choice for emergent/urgent dosing of an epidural for cesarean section. It is favorable because of its rapid onset, which is independent of its pKa (based on pKa alone, one would expect a very slow onset). The rapid onset is thought to be due to the high concentrations that are used. It is safe because it is metabolized by plasma cholinesterases (it is an ester local anesthetic), so intravascular injection is clinically inconsequential. A down side of its use is its relatively short duration; repeat boluses must be given about every 30 minutes to maintain surgical anesthesia. The use of 2-chloroprocaine is associated with a decreased efficacy of subsequent epidural opioids, rather than increased efficacy.
