Efficacy and Safety of Dexmedetomidine to Bupivacaine in Supraclavicular Brachial Plexus Block

March 31, 2024 updated by: Gamal Hendawy Shams, Kafrelsheikh University

Efficacy and Safety of Dexmedetomidine to 20ml Bupivacaine in Supraclavicular Brachial Plexus Block

The study aims to evaluate the analgesic efficacy and safety of addition of 1µg/kg dexmedetomidine to 20ml bupivacaine compared to 20ml and 30ml bupivacaine without additives in ultrasound-guided supraclavicular brachial plexus block for anesthesia.

Study Overview

Detailed Description

Dexmedetomidine, a highly selective α2 adrenergic agonist, has been used as an adjuvant to local anesthetics. Various clinical trials performed have shown dexmedetomidine to be safe when used as an adjuvant to local anesthetic in subarachnoid, caudal, and epidural Different doses of dexmedetomidine are commonly used as an additive in Ultrasound-guided supraclavicular brachial plexus block, 1 μg/kg and 2 μg/kg in which a high dose of dexmedetomidine does not prolong the duration of analgesia, but it is associated with lower heart rate and blood pressure. Incidence of hypotension and bradycardia is also more. Hence, a lower dose of 1 μg/kg dexmedetomidine is a good balance between safety and efficacy

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Success rate.
Time Frame: 30 minutes after block performance
Sensory and motor block evaluation will be done every 3 min after giving the block until complete sensory and motor block or 30 min, whichever will be earlier.
30 minutes after block performance

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total pethidine consumption.
Time Frame: 24 hours postoperative.
Visual analog scale ≥ 4 indicates the analgesic requirements. The patient will be given supplementary pethidine I.V. injection in a dose of 0.5 mg as rescue analgesia. Total pethidine consumption postoperative in the 1st 24 hours will be measured.
24 hours postoperative.
Mean arterial blood pressure
Time Frame: From preoperatively till the end of surgery
Mean arterial blood pressure from preoperatively, after block, then every 15 minutes intraoperative till the end of surgery.
From preoperatively till the end of surgery
Heart rate
Time Frame: From preoperatively till the end of surgery
Heart rate from preoperatively, after block, then every 15 minutes intraoperative till the end of surgery.
From preoperatively till the end of surgery
Postoperative side effects.
Time Frame: 24 hours postoperative
Complication related to the block or adverse events of the administered drugs.
24 hours postoperative
Pain score.
Time Frame: 24 hours postoperative.

Pain score will be measured by visual analogue scale (VAS) at 30 minutes and then at 2, 4, 6, 12, 18 and 24 hours postoperative.

The VAS consists of a 10cm line, with two end points representing 0 (no pain) and 10 (pain as bad as it could possibly be).

24 hours postoperative.
