Background: Brachial plexus block is useful technique that serves as a valuable alternative to general anesthesia for procedures involving the upper limbs. It provides optimal muscle relaxation, stable intra-operative hemodynamics and effective post-operative pain control.
The purpose of this work was to assess the effectiveness of adding midazolam to local anesthetic mixture (lidocaine /bupivacaine) for analgesia and anesthesia in supraclavicular block with ultrasound-guidance during upper limb surgeries.
Patients and methods: 40 patients from those scheduled to unilateral upper limb surgery below the level of midarm.at our hospital. The patients were allocated into two equal groups. Group ''M'' (lidocaine bupivacaine) mixture + Midazolam, and group ''C'' (lidocaine bupivacaine). Results Our results showed that there was no difference between the two groups regarding sensory onset. In contrast, patients in group M showed an earlier onset of motor block. Furthermore, both sensory and motor block durations were longer in Midazolam than control group. There was no difference between the 2 groups regarding respiratory rate, ECG, blood pressure, pulse rate and oxygen saturation.
Conclusion: From of the findings of this study, we conclude that adding midazolam to mixture of bupivacaine 0.25 % and Lidocaine 1 % for supraclavicular brachial plexus block results in rapid onset of sensory block and prolongs both sensory and motor block duration.
