Clinical Trial Summary

The etiology of tourniquet pain is complex, and the study team hypothesizes that blocking with Interscalene brachial plexus block (ISBPB) is more efficient in decreasing the incidence of tourniquet pain in comparison with other techniques. As there is a paucity of studies that evaluate the effect of intercostobrachial nerve (ICBN) block and ISBPB and Patient-Controlled Analgesia (PCA) with a supraclavicular brachial plexus block (SCBPB) on tourniquet pain in forearm surgery, Therefore, we established this randomized study to compare ISBPB and ICBN and PCA with fentanyl with SCBPB in terms of the incidence and severity of tourniquet pain in patients undergoing forearm surgery.

Intervention

Drug:
• bupivacaine, midazolam
Patients will be provided with midazolam (up to 2 mg) if requested. No opioids will be administered before the incision. At the first patient complaint of pain, the intraoperative anesthesia team will document the quality and location of pain, and 50 microgram of fentanyl will be administered if the patient requested it or pain score more than 3

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The incidence of tourniquet pain	The incidence of tourniquet pain will be assessed by the patient's VAS score. The Visual Analogue Scale (VAS) measures pain intensity. 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'). The patient is asked to rate their current level of pain by placing a mark on the line.	2 hours
Secondary	Hemodynamics	Hemodynamics up to 2 hours postoperative (heart rate, mean arterial blood pressure. Mean arterial blood pressure and heart rate will be recorded at baseline and every 5 min till the end of the procedure.	2 hours
Secondary	The incidence of adverse reactions	The incidence of adverse reactions (Pneumothorax, Horner's syndrome) will be evaluated.	2 hours
Secondary	Patients' satisfaction	Patients' satisfaction will be measured immediately postoperative and after 24 hours using a five-point Likert scale consisting of "very dissatisfied," "dissatisfied," "unsure," "satisfied," and "very satisfied.	24 hours
