Using radius hematoma block method can provide good anesthesia in distal radius fractures, but sometimes it is difficult to do it using anatomical landmarks. Performing the block procedure under ultrasound guidance can improve the success rate of the block and pain relief during delivery.

In this double-blind clinical trial study, 100 patients over 15 years of age with acute distal radius fracture were randomly assigned to two groups of hematoma block without ultrasound guidance and hematoma block with ultrasound guidance (47 people). Examining the amount of pain during block and insertion based on a Likert scale of 0 to 10 (0=no pain and 10=most pain) during insertion and half an hour after insertion was done and compared in two groups.

In this study, 69% of participating patients were women, the average age of patients in the group with ultrasound guidance was 47.25 years and in the group without ultrasound guidance was 55.16 years. The average number of VAS during descent in the group with ultrasound guidance and without ultrasound guidance was 5.42 and 5.81, respectively, and half an hour later, it was 1.91 and 2.33, respectively.

It seems that performing hematoma block under ultrasound guidance especially in cases where there are no suitable local landmarks or for reasons such as swelling of soft tissue, bone anatomy, crushing of fracture fragments, or the presence of interfering factors in diagnosing the exact location of the fracture. Hematoma block becomes complicated and difficult, it can be very helpful.

Forearm distal fractures are of the most common Fractures in the upper organs. To fix such deformities, hematoma block approach can be applied. Less time, costs, and side effects are of the advantages of this approach, but in some cases a full paninlessness may not be achieved. Thus, The study was purposed to add intravenous phentanil to this approach to provide a better painlessness. Material &

In a clinical experimentation, 40 candidates For surgical refixation of acate forearm under hematoma block aenesthesia were randomly investigated in two case and report groups. Lido caine 1% at 1 mg/kg in the hematoma site and 0.5 mg/kg round the osteoloied angle + intravenous Normal salin (plasbo) was used. Then the same lideocaine dose + 2µg/kg of intravenous Phentanil (5 minutes before the blockage) was injected. Afterward, the patient's tensity was assessed during the injection and fixation.

Both the groups, were under the same condition regarding age and sex. The finds showed that the pain during blocking as well as fixation was significantly more intense in the report group than the case one (P= 0.001).

It is concluded that applying the hematoma block method along with intravenous Phentanil decrease the pain all during the blocking as well as fixation process significantly, So more accepted by referring patients.
