Comparing the effectiveness of adding dexmedetomidine to standard Walant solution in local anesthesia of patients with distal radius fracture on postoperative complications.

Comparison of the results of using Walant solution together with dexmedetomidine on block duration, block initiation and postoperative analgesia with Walant solution alone in distal radius fracture surgery

در یک گروه تکنیک های WALANT (بی حسی موضعی بیدار کامل بدون استفاده از تورنیکت) در محل جراحی و در گروه دیگر همین تکنیک که به آن محلول دکسمدتومیدین اضافه شده است تزریق می شود

After transferring the patient to the operation room of Shahada Tajrish hospital and standard monitoring and fluid therapy, oxygen 5 lit/min is prescribed through a mask and then Walant solution containing 20 ml of lidocaine 2% along with 2 CC of epinephrine vial 1000/01 to Along with 14 CC of normal saline and 4 CC of 8.4% sodium bicarbonate (40 CC in total) for the control group and the same solution plus 5 micrograms per kilogram of body weight of dexmedetomidine for the intervention group is injected at the operation site.

Patients aged 18 to 80 years with distal radius fracture are included in the study, and patients with active site infection, peripheral vascular disease, anxiety, severe fear of injection, impaired coagulation profile, open fracture, and fracture more than 3 weeks old are excluded

In the control group, surgery with local anesthesia of Walant solution containing 20 ml of lidocaine 2% along with 2 CC of epinephrine 01/1000 vial along with 14 CC of normal saline and 4 CC of sodium bicarbonate 8.4%, a total of 40 CC and in the group The intervention of this solution plus 5 micrograms per kilogram of dexmedetomidine is used

The amount of pain during and after surgery, the hemodynamic status during surgery, the amount of bleeding during surgery and the limitation of wrist movements after surgery

Block randomization will be done by dividing included patients into some blocks of size 2n( 2,4,6,8 and...), then randomizing patients in each block will be done such that n patients are allocated to the experimental group and control group. then we will choose the blocks randomly. This method ensures equal treatment allocation within each block when the complete block is used.
