Abstract
Introduction:Regional anaesthesia is a well accepted component of comprehensive anaesthetic care. Its role has expanded from the operating suite into the arena of postoperative and chronic pain management. Aims and objectives: comparative study was carried out to evaluate the analgesic efficacy and side effects of addition of fentanyl to levobupivacaine (0.5%) in Supraclavicular brachial plexus block. Materials and Methods:Patients were randomly divided into two groups: group I (control) and group II (study). All the patients were subjected to brachial plexus block with supraclavicular approach. After obtaining paraesthesia, drugs were administered as follows: Group 1 (control group):- 0.5%plain Levobupivacaine - 30cc+2cc NS.Group 2 (Study Group):- 0.50% levobupivacaine-30cc +(2ml) Fentanyl(100mcg). Observations were noted. All the relevant information was recorded. Regular monitoring of PR, BP and RR, side effects,degree of sedation were recorded. Results: The addition of fentanyl to local anesthetics caused a delayed onset of analgesia. We hypothesized that the changes in pH of anesthetic solutions could be responsible for this effect.Conclusion : It increases the success rate and prolong the duration of analgesia,but it delays the onset time of sensory blockade as compared with that achieved by the same doses of local anesthetics used in combination.
