A Comparative Study of Two Different Doses of Hyperbaric 0.5% Bupivacaine on Saddle Anaesthesia for Perianal Surgeries ? A Prospective Study

This study was designed in a prospective manner to compare for effects of low dose4.5mg of bupivacaine over high dose 5.5mg used along with 30mcg buprenorphine for intra and post-operative analgesia in saddle block for perianal surgeries in patients admitted in shri aurobindo institute of medical sciences indore. Attempts have been made to tailor spinal anaesthesia dose for specific surgical procedures. Several studies targeting local anaesthetic at specific nerve roots supplying the surgical field have demonstrated successful results.2, 3 However, little research has been published concerning spinal saddle block. This study was designed to examine the efficacy of low dose 4.5mg bupivacaine for blockade of the nerve supply of the surgical field in perianal procedures compared with the dose 5.5mg use for saddle anaesthesia, both with 30ug buprenorphine in addition for post operative analgesia.4, 5 After overnight fasting, blood samples was drawn for complete hemogram, blood urea, serum creatinine, lipid profile. Descriptive and inferential statistical analyses were performed using SPSS version 20.0.
