Abstract

CP is an amino-ester local anesthetic with a very short half-life. It was introduced and has been successfully used for spinal anesthesia since 1952. Sodium bisulfite was then added as a preservative after 1956 to the commercially available CP preparation. The drug was used as an epidural anesthetic for obstetric patients. After obtaining the approval from institutional review board and the ethical committee, 60 ASA Grade I and Grade II patients who met inclusion and exclusion criteria who were undergoing short duration urology, lower limb and perianal surgeries were selected. The independent ‘t’ test result shows that there is a significant difference in mean of return to bromage 0 (min) between the groups with Chloroprocaine with fentanyl group taking longer time to bromage 0(<0.001*). The independent ‘t’ test result shows that there is a significant difference in mean of time to rescue analgesia(min) between the groups with Chloroprocaine with fentanyl group requiring longer time for analgesia(<0.001*).
