Supraclavicular Brachial Plexus Block During Upper Limb Surgeries

Status Completed

Clinical Trial Summary

Comparative Study Between Ketamine-Bupivacaine Versus Bupivacaine With Intravenous Ketamine Infusion In Supraclavicular Brachial Plexus Block During Upper limb Surgeries The techniques of regional anesthesia have become very popular as they provide several advantages in comparison with general anesthesia and systemic analgesia. They provide perfect pain control, decreased complications and reduced post-anesthesia care unit stay. Regional anesthesia provides more patient safety and better outcomes, which leads to the fact that ultrasound-guided regional anesthesia became more popular. Ultrasound provides clinicians with real-time images which are useful for better identification of the anatomical structures, safe needle placement and adequate local anesthetic spread. Brachial plexus blocks are commonly achieved via an interscalene, supraclavicular, infraclavicular or axillary approach. The supraclavicular level is an ideal site to achieve anesthesia of the entire upper extremity just distal to the shoulder as the plexus remains relatively tightly packed at this level, resulting in a rapid and high-quality block. For this reason, the supraclavicular block is often called the ''spinal of the arm'' Using the local anesthetics alone for supraclavicular brachial plexus block provide good operative conditions but have the disadvantage of shorter duration of postoperative analgesia. Various adjuvants such as opioids, dexmedetomidine, dexamethasone, midazolam, ketamine, etc., were added to local anesthetics in brachial plexus block to achieve quick and prolonged block. Ketamine is a noncompetitive antagonist of the N-methyl-D aspartate receptor(NMDAR). It is used as a premedication, and for sedation, induction and maintenance of general anesthesia. Local anesthetic and analgesic properties have been reported for ketamine. Intravenous administration of low-dose ketamine decreases postoperative opioid use and improves analgesia. Ketamine has been added to bupivacaine to prolong the duration of regional anesthesia and postoperative analgesia.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
