Intrathecal Isobaric Bupivacaine Fentanyl Mixture Versus Hyperbaric Bupivacaine Fentanyl Mixture in Urological Procedures- A Comparative Study

Intrathecal Isobaric Bupivacaine Fentanyl Mixture Versus Hyperbaric Bupivacaine Fentanyl

Abstract

Background: Comparison of intrathecal isobaric bupivacaine fentanyl mixture and hyperbaric bupivacaine fentanyl mixture in urological procedures.  Subjects and Methods: One hundred ten patients undergoing urological procedures were divided into 2 equal groups was done. Group 1 patients received 3 ml of 0.5% isobaric bupivacaine with 25 g fentanyl and group 2 received 3 ml of 0.5% hyperbaric bupivacaine with 25 g fentanyl. Parameters such as blood pressure, onset and duration of motor and sensory blockade was recorded. Results: There was significant difference in mean systolic and diastolic blood pressure in both groups (P< 0.05). The mean onset of sensory block was 4.5 minutes in group 1 and 1.2 minutes in group 2, onset of motor block was 5.2 minutes in group 1 and 1.1 minutes in group 2, mean duration of sensory block was 2.4 minutes in group 1 and 3.6 minutes in group 2 and mean duration of motor block was 2.8 minutes in group 1 and 3.8 minutes in group 2. Conclusion: Intrathecal isobaric bupivacaine fentanyl mixture was associated with better haemodynamic stability and lesser duration of both sensory and motor blockade.
