Abstract

Aims & Objective: The present study was designed to investigate saddle anesthesia with different doses of chloroprocaine at the same concentration (0.5%, w/v) in terms of extent of sensory and motor block, recovery from block, time for ambulation and time for urinary voiding.
Materials and Methods: The study was conducted in the department of Anaesthesiology of a tertiary healthcare centre of southern Rajasthan. 120 patients of either sex, aged between 20-50 years, with American Society of Anaesthesiologists grade I/II scheduled for elective perianal surgery in lithotomy position (duration < 40 n=40/group),> Results: All the three groups were comparable with no statistical difference in terms of age, weight, height, BMI, ASA grading and site of injection among the participants of the groups. Number of patients who were able to move from stretcher to operation table and again from operation table to stretcher without help did not differ significantly among all the three groups. Similarly, there was no statistically significant difference in pre operative and post operative Bromage scores of participants among three groups (p value > 0.05).
There was significant difference in the number of anaesthetized dermatomes both pre and post operatively among all the three groups (p value <0> Conclusion: 10 mg chloroprocaine may cause early post operative pain while 30 mg dose may cause delayed unassisted ambulation and urinary voiding postoperatively so 15 mg dose can be used as minimum optimal dose for saddle anaesthesia for ultra-short perianal procedures.
