BACKGROUND
This study aims to document the characteristics of caudal epidural block with lignocaine in adults undergoing anorectal surgeries, to assess the effect of adding ketamine as an adjuvant to lignocaine in caudal epidural block, in adults undergoing anorectal surgeries. We also wanted to compare the characteristics of caudal epidural block in lignocaine group and lignocaine with Ketamine group, along with the side effects of lignocaine group and lignocaine with ketamine group.
MATERIALS & METHODS
This was a Randomized control study conducted in the Department of Anesthesiology, Sri Venkateshwara Ramnarayan Ruia (SVRRGGH), Tirupati for 1 year from the date of approval from IEC and scientific committee. Total of 50 patients were selected and divided into two groups and were classified as Group L (n=25) (30 mL of 1.5% lignocaine caudal) and Group LK (n=25) (30ml of 1.5% lignocaine +ketamine 0.5 mg/kg). Patients of age between 20-60 years who were undergoing anorectal surgeries are included and classified as Grade 1 and 2. People who were hemodynamically and neurologically unstable, morbid obese patients, and who did not agree to give written informed consent are excluded.
RESULTS
The mean time to onset of anesthesia was 6.04 and 5.16 in Group C & Group T respectively. Both the groups were compared and found statistically significant (P value < 0.05).Group C had 2.56 and Group T had 3.08 as mean sedation score. Both the groups were compared and found statistically significant (P value < 0.05).
CONCLUSION
The caudal epidural block (CEB) using 30ml of lignocaine was demonstrated to be safe, reliable, and simple technique for anorectal surgeries in this study involving 50 adult patients. When administered as an adjuvant in sub- anesthetic doses, ketamine significantly enhances both quality and duration of the caudal block, as well as improves patient comfort.
