Comparative Study of Small Dose Bupivacaine-fentanyl vs. Normal Dose of Bupivacaine in Spinal Anaesthesia for Patient Above 60 Years Old Undergoing Surgery

Abstract

The purpose of the study was to compare small dose bupivacaine - fentanyl and normal dose of bupivacaine
in spinal anaesthesia for patient above 60 years old undergoing femoral and tibial surgery 80 elderly patients
of either sex belonging toASAI, II & III undergoing elective orthopedic lower limb surgeries underspinal
anaesthesia were studied in this prospective, randomized double blinded study. First group A (n=40) wasgiven
inj. Bupivacaine hyperbaric 3 ml (15mg) & group B (n=40) was given inj. Bupivacaine (2 cc) + 25 mcg
fentanyl Parameters like time for adequate level of analgesia (T9), peak sensory level reached,beginning
of motor block to receed to L3-L4 level (modified bromage scale), how long sensory block continue and
number of complications are noted in both groups result: The time of adequate level of sensory block to be
started (T9) was longer for group Bthan group A. How long of sensory block to be started was slightly more
for group A. the time of motor block continue to work was more in A than group B. It is concluded that
subarachnoid block with 2cc bupivacaine 0.5%H and 25mcgfentanyl is a more safer and better option for
patient above 60 years of age undergoing femoral and tibial surgeries.
