Abstract :
Aims: To compare the clinical efficacy of 1% 2-chloroprocaine and 0.5% bupivacaine heavy for saddle block in patients undergoing perianal day care surgeries.
Settings and Design: After obtaining Institutional ethical clearance and written informed consent, 80 patients posted for elective perianal surgeries at SNMC and HSK Hospital were allocated into two groups by computer generated random numbers (1:1 ratio). Group A received 2ml of 1% 2-Chloroprocaine and Group B received 2ml of 0.5% Bupivacaine heavy. Double-blinding was done where neither the patient nor the investigator knew about the drug.
Materials and Methods: In the OT standard anesthetic protocols were employed. Saddle block was given with bupivacaine heavy and 2-chloroprocaine and the following parameters, time to eligibility for discharge from hospital, length of stay in PACU, time to ambulate and void urine and any other complications were noted.
Statistical analysis used: Data were entered in MS-Excel and analysed in SPSS V22. Descriptive statistics were represented with percentages, Mean with SD. Chi-square test, Independent t-test were calculated. P
Results: Mean time for eligibility to discharge from hospital between groups were statistically significant with group A having less mean time (235.8 22.8 min) as compared to group B(337.1 16.4 min).
Conclusion: Saddle block with 2-Chloroprocaine in perianal day care surgeries provides adequate duration and depth of surgical anesthesia with the advantages of faster block resolution and earlier hospital discharge.
