Chloroprocaine and lidocaine decrease hospital stay and admission rate after outpatient epidural anesthesia . Lumbar epidural anesthesia with 20 ml of either 3 % 2-chloroprocaine ( C ) , 1.5 % lidocaine ( L ) , or 1.5 % mepivacaine ( M ) with epinephrine was studied in 84 outpatients undergoing surgery ( extracorporeal shock wave lithotripsy ( ESWL ] . The average duration of the procedure was 31.9 minutes . The total duration of sensory anesthesia was 133 +/- 28 minutes ( C ) , 182 +/- 38 ( L ) , and 247 +/- 42 ( M ) ( p less than 0.05 ) . Times to discharge were 269 +/- 62 minutes ( C ) , 284 +/- 62 ( L ) , and 357 +/- 71 ( M ) . The time to discharge with M , almost six hours , was significantly longer than with C or L. There was a trend to an increasing rate of unplanned overnight hospital admission with increasing duration of the local anesthetic drug employed . Continuous epidural anesthesia with C , L or M appears safe and effective for outpatient surgical procedures such as ESWL . In contrast to previous understanding , mepivacaine produces significantly longer anesthesia and recovery times and may not be optimal for outpatient epidural use .
