Infraclavicular Brachial Plexus Block With Bupivacaine Alone or With Both Dexmedetomidine and Dexamethasone
- Conditions
- Upper Extremity Injury
- Interventions
- Registration Number
- NCT06356415
- Lead Sponsor
- Suez Canal University
- Brief Summary
Upper-extremity regional anesthetic techniques, using brachial plexus blockade, have been shown to reduce adverse effects related to opioid administration, improve patient satisfaction, and provide significantly improved analgesia immediately following these surgeries. Many medications have been investigated to extend and enhance long-acting local anesthetics' (LA) analgesic effects. Currently, dexamethasone and dexmedetomidine have been studied, looking for an optimal long-lasting single-shot nerve block. In general, adjuvants have been used in peripheral nerve blocks to accelerate onset, decrease plasmatic absorption and secondary toxic effects, and prolong the block effects.
- Detailed Description
Brachial plexus blockade-based upper-extremity regional anesthetic approaches have been demonstrated to lessen opioid administration side effects, increase patient satisfaction, and offer noticeably better analgesia right after these surgeries. A lot of drugs have been tested to prolong and improve the analgesic effect of long-acting local anesthetics (LA). Currently, dexamethasone and dexmedetomidine have been studied, looking for an optimal, long-lasting single-shot nerve block. Adjuvants have generally been employed in peripheral nerve blocks to lengthen the block effects, limit secondary toxic effects and plasmatic absorption, and speed the onset of the block. Objectives: To compare the effects of adding dexmedetomidine and dexamethasone to bupivacaine on the start of sensory blockade in an infraclavicular brachial plexus block. Patients and Methods: A prospective, randomized controlled trial will be conducted on patients who are undergoing hand or forearm surgeries. Patients who will be eligible for the study will be divided into 2 groups. The first group will receive dexmedetomidine and dexamethasone as adjuvants to bupivacaine, while the second group will receive bupivacaine alone. Expected Results: The success rate, onset time, duration of the block, and possible adverse events.

Group Intervention Description Bupivacaine+ Dexamethasone+ Dexmedetomidine Bupivacaine+ Dexamethasone+ Dexmedetomidine Patients will undergo an ultrasound-guided infraclavicular brachial plexus block using bupivacaine combined with dexmedetomidine and dexamethasone. Bupivacaine Bupivacaine injection Patients will undergo an ultrasound-guided infraclavicular brachial plexus block using bupivacaine alone.
- Primary Outcome Measures
Name Time Method Onset of sensory block Immediately after the performance of the infraclavicular block Comparing the number of minutes required to achieve total upper limb sensory blockade following the application of an infraclavicular brachial plexus block that includes both dexmedetomidine and dexamethasone in addition to bupivacaine, as opposed to merely using bupivacaine on its own.
