About

In this study, we will assess the effect of combined Dexmedetomidine and Bupivacaine analgesia on the onset and duration of anesthesia in supraclavicular plexus block compared to Bupivacaine alone.

Full description

Participants who fulfill the inclusion criteria will be enrolled in this study to achieve sample size of 140 participants, 70 participants in each group.

Participants were blindly randomized into two groups: group A (Bupivacaine alone) and group B (Bupivacaine with Dexmedetomidine).

On the morning of the surgery day, and before performing the procedure on the targeted hand, a venous cannula 18gauze was secured on the opposite hand. Routine monitors like pulse oximetry, non-invasive blood pressure, and electrocardiogram were attached during the procedure.

Study medications were prepared for each group, which is Bupivacaine (30ml) only for group A and Bupivacaine (30 ml) with Dexmedetomidine (1 mcg /kg) for group B. Then, SCPB was done under ultrasound guidance which increases the safety due to improved monitoring of anatomy and needle placement. A needle was placed within the brachial plexus sheath posterior to the subclavian artery, and the local anesthetic injected to surround the trunks and divisions of the brachial plexus at this level.

Patients were evaluated for the onset of the sensory and motor block every 3 minutes after completion of injection till their onset, and, at 15, 30, 45, 60, 90, and 120 min; and then hourly (even after surgery), until they had resolved.
