Background: Ambulatory surgeries are increasing all over. While searching for an ideal anesthetic, the use of lidocaine was linked to a greater rate of transitory neurological symptoms and bupivacaine delays discharge due to a longer duration of motor blockade. 2-chloroprocaine (2CP) with a shorter duration of action is gaining popularity. We aimed to compare intrathecal bupivacaine and 2CP for the subarachnoid block for elective ambulatory gynecological surgeries. Methods: A single-blind study was conducted on 90 patients comparing 40 mg 2CP and 10 mg 0.5% bupivacaine heavy measuring pinprick sensation, motor block, time to ambulation, and voiding of urine so as to get ready for discharge. Results: In both groups, the beginning of sensory blockage occurred at a similar time, while motor blockade achieved was faster in the 2CP group. The resolution of motor blockade was 1.7 times faster in the 2CP group than in the bupivacaine group. Time taken for ambulation was delayed significantly in the bupivacaine group, i.e., 263.04 ± 29.08 min compared to the 2CP group, i.e., 225.44 ± 29.48 min which was a delay of almost 38 min. Voiding of urine was also delayed in the bupivacaine group by 60 min compared to the 2CP group and was significant finding leading to delay of discharge of patients. Adverse effects were comparable in both groups. Conclusion: Intrathecal preservative-free 2CP provides satisfactory surgical block, and has a considerably faster rate of block regression, resulting in earlier ambulation and voiding, allowing the patient to be discharged from the hospital sooner as compared to intrathecal bupivacaine.
